Description
The application is that application number is 99119257.5, the applying date is on August 27th, 1999, denomination of invention is divided an application for " printed matter with the shaped device of cutting blade ".
Technical field
Present invention relates in general to the shaped device of a kind of printed matter with cutting blade, though relate in particular to a kind of can the metal tape size, by associated working, by suitably crooked and the blade that metal tape cuts into requirement is made a kind of like this device of cutting blade.
Background technology
For producing various open and flat printed matters or printed apcksging material, as carton or thermoplastic film, need to cut open and flat printed matter or film,, need the line of cut cutting that before plate is made box, designs along printed paperboard to the box type packages material along the line of cut that designs.
Such single-blade cutting blade that must extend with the line of cut that the edge designs for the cutting operation of producing open and flat printed matter, carton or thermoplastic film be finished.Such cutting blade places has identical height on the flat plank.Under these circumstances, outside the single-blade sharpening of blade faces.Plank and cutting blade are installed to together and are used to cut the so open and flat printed matter or the forcing press of packaging material.
Typical cutting blade is by producing the thin steel band dicing of special use.A kind of like this steel band has band like form and is standing curved and cutting the Cheng Qian with sharpening on one side.Such metal tape must be bent and cut into the cutting blade that forms the line of cut that designs separately respectively, and open and flat printed matter or packaging material are cut by the line of cut cutting blade along above-mentioned.After metal tape is bent and cuts into cutting blade, one or more cutting blades are placed on the plank.So it is accurately crooked and cut into cutting blade that primary is with metal tape.In addition, metal tape is also handled by a plurality of as described below minute process.
For example, metal tape must so form the bridge mouth regularly at the following opening relative with the sharpening limit on the base.Such bridge mouth is used for firmly being the cutting blade location when blade places on the plank.That is, the bridge mouth is almost completely avoided the accidental change that the desired location of the cutting blade on plank causes owing to external impact.
Sometimes, be necessary to make a plurality of V-shaped parts, so make the cutting blade that is preferred on printed matter such as stamp, making line of perforation along the sharpening limit of metal tape.Sometimes, metal tape can be by right-angle bending.Under these circumstances, before pressing the quarter bend metal tape, on the side of metal tape, need laterally to make a curved groove.When metal tape must be accurately crooked, preferably manually rather than mechanically curved metal tape, this made before the artificial bending metals band, and metal tape is through the marking procedures of the curved point of system thereon.
Certainly, minute process of above-mentioned system bridge mouth, V-shaped part, curved groove and curved point is that industry technical staff knows.
Yet in known blade manufacturing installation, these processes are not to finish by associated working, but respectively with select to finish, so known devices do not reach permissible accuracy, and the production cost that reduces productivity ratio and increase cutting blade.
In known devices, the process that metal tape is cut into the cutting blade of requirement is separately finished by above-mentioned minute process, therefore greatly reduces productivity ratio and the production cost that has increased cutting blade.
For overcoming these shortcomings, the long metal tape that has the sharpening limit can be wrapped on the feed roller so as forcibly, continuously from feed roller to curved mouth feed.A position near curved mouth, metal tape requires a plurality of loopers of shape to contact with being used for metal tape curved.
Know as the insider, this BENDING PROCESS with looper is computer numerically controlled.That is, a plurality of loopers are arranged near the curved mouth, according to the control signal of computer output, accurately rotate by relative direction, and so the metal tape of curved mouth is come from bending.Such bending process is referring to for example Japanese patent application publication No. Heisei 899,123.
In typical blade shaped device, before metal tape arrives curved mouth, can be cut to a plurality of metal segments with the length of designing.In brief, can be before the curved metal tape with its segment.
In addition, can be disclosed as Japanese patent application publication No. heisei 8-243834, behind bending operation, metal tape can be cut into multi-disc.In this Japan Patent, the metal tape that comes from curved mouth repeatedly along opposite direction bending up to owing to fatigue fracture is cut off.Yet the typical blade shaped device exists them can not produce high-quality cutting blade and the problem that can not produce cutting blade by associated working.That is, the shape of cutting the bridge mould that is installed on the exemplary device is fixed, and the spacing or the shape that therefore change the bridge mouth of metal tape almost are impossible.And exemplary device must separately be finished the process of making this bridge mouth on metal tape, and the result reduces device productivity ratio and increases the production cost of cutting blade.
Another problem of typical blade shaped device requires the looper of shape to cause by being used for metal tape curved.That is, looper must be fixed by the fixture of complexity, and the structure of cutting blade shaped device is complicated.In addition, accurately adjust the bent angle of looper but do not cause that error almost is impossible.When metal tape at cutting action after when handling by bending, crooked in the middle of cutting blade accumulated error is arranged, this makes the cutting blade precision very low.
And when having the wearing and tearing of looper at least, just possible accuracy is determined the center of looper hardly.Under these circumstances, looper has to rearrange singly, when bending metal tape, has just reduced operating efficiency like this.In the BENDING PROCESS that adopts exemplary device, the sharpening limit of metal tape contacts with looper, therefore may damage the sharpening limit.
The sixty-four dollar question that the typical blade shaped device has results from cutting process.That is since the metal tape that comes from bending operation by repeatedly in opposite direction the bending metals band up to it because the fatigue fracture section of being cut into, the limit that cuts off metal tape institute edge is just unsmooth, but very coarse thorniness, has so just destroyed the profile of cutting blade.
For eliminating this burr on the cutting blade, the polishing that the blade of having to adds is handled.And, after the metal tape section of being cut into, be necessary these sections of final machined so that produce qualified blade, and this forces the metal tape that is cut into pieces to face the machining allowance problem.Because this machining allowance may be produced high-precision blade hardly.
So, preferably by associated working, when accurately adjusting the bent angle of looper and accurately metal being cut into cutting blade, finish the operation of on metal tape, making the bridge mouth, metal tape is curved the shape that designs and metal tape is cut into cutting cut into slices.Under these circumstances, cutting is produced cutting blade and can be avoided any additional machined.
In addition, the blade shaped device should be handled the metal tape with different size flexibly.If necessary, the blade shaped device also should be designed for effectively metal tape being curved difformity.
Summary of the invention
Therefore, the present invention has noticed the problems referred to above that existed in the former technology, an object of the present invention is to provide the shaped device of a kind of printed matter with cutting blade, the mould of this device is replaceable, therefore can make bridge mouth with different spacing and shape, no matter and this device metal tape size, by associated working, by suitably crooked and the blade that metal tape cuts into requirement made cutting blade.

For forming the recessed 1a of such bridge, cut bridge type mould 20 and must be contained on the device 100.For pattern 20 is installed on the device 100, one of guide pad 2 is movably, so that for being installed in opening of formation on the device 100 cutting bridge type mould 20.Perhaps, the shell top of cover guide pad 2 can will cut bridge type mould 20 and be installed to device 100 with front opening from installing 100 tops.
Certainly just should be understood that and cut the bridge type mould that device 100 can have two or more openings.Under these circumstances, two or more have a difference in functionality to the opening that is used to cut the bridge type mould cuts the bridge type mould near arranging and establishing simultaneously on device 100 mutually.
Shown in Figure 18 and 19, the shell of guide pad 2 comprises two plates: be oppositely disposed in top board and base plate 3 on the device 100, a vertically arranged curved piece 4 is arranged between two plates 3.Each plate 3 is all being had a fixedly elongated slot 3a by the surface, this makes the top side and the bottom side of curved piece 4 be fixed by the groove 3a of two plates 3.The above-mentioned shell that comprises two plates 3 and curved piece 4 is arranged on the device 100 in the flat this mode of a line of mouthful horizontal saliva of taking out of of curved piece 4 with two guide pads 2.
Above-mentioned curved piece 4 has a curved mouth 4a at front end, so that the metal tape 1 of the bridge type mould 20 of autotomying is introduced into curved mouth 4a.In the present invention, curved piece 4 can be with becoming according to the size of metal tape 1 and the other piece 4 of profile.That is, in device 100 of the present invention, curved piece 4 is variable, therefore the form that can change curved mouth 4a according to the size and the profile of metal tape 1.This variable curved piece 4 is fixing by the plate 3 of special use simultaneously, so plate 3 must change together with curved piece 4.
In device 100 work therebetween, metal tape 1 is curved preceding under the control of numerical control program, and constantly the curved mouth 4a from piece 4 is assigned with.One or more guiding loopers 31 are movably disposed within a side of the front end of curved piece 4 in vertical mobile this mode.Above-mentioned pin 31 is fixed by two gears of upper and lower end and can be driven backward rotation by reversible stepper motor 30.
Under these circumstances, two compressing rollers 60 and 60a are disposed in the appropriate location relevant with guide pad 2.In the present invention, preferably two rollers 60 and 60a are arranged in the entry and exit of guide pad 2.Two rollers 60 and 60a are with the guide portion of suitable pressure pressure metal tape 1, and this feasible metal tape 1 from guide pad 2 moves but keeps a height.
Two guide rails 11 that each all has a predetermined length are erected at a curved mouth 4a place in addition vertically oppositely.One first actuating cylinder 41 is arranged vertically between two guide rails 11.First actuating cylinder 41 can be worked according to the BENDING PROCESS termination signal.The piston of above-mentioned actuating cylinder 41 connects with removable supporting plate 40, so supporting plate 40 can vertically slide under the guiding of two guide rails 11.Admittedly be with device 42 to be fixed on center, 40 end of above-mentioned supporting plate for one by screw, in order that be with admittedly device 42 can with an other replacing.Above-mentioned device 42 cutting perpendicularly that makes progress from the lower end of being with admittedly forms a vertical incision like this, and the width of this otch is similar with width with the thickness of metal tape 1 with the degree of depth.Swing cutter 43 and supporting plate 40 are hinged and be formed at cutter 43 and be arranged in above-mentioned admittedly with the front of device 42 admittedly with the minim gap between the device 42 with one.Above-mentioned swing cutter 43 drives by horizontally disposed second actuating cylinder 44 in supporting plate 40 1 sides.
Above-mentioned actuating cylinder 44 drives swing cutter 43 according to the angle or the preset program of the metal tape 1 that detects.When supporting plate 40 descends under the guiding of guide rail 11, admittedly be with at first fixing metal band 1 of device 42.Under these circumstances, admittedly fix with the position of device 42, so almost completely avoid metal tape 1 to move in the cutting process.
Admittedly be with device 42 for fixing, the front end of stand 10 is shaped on slit 45.The front end of slit 45 is shaped on horizontal guide slot 46.An end face has the displaceable member 48 of locked groove 47, designs above-mentioned gathering sill 46 movably.The lower end of displaceable member 48 fixing swing cutter 43 at locked groove 47 places.
Above-mentioned displaceable member 48 connects by an actuating cylinder in link motion and the stand 10, so as part 48 can be in gathering sill 46 move left and right.Swing cutter 43 like this by second actuating cylinder 44 along the relative direction quick rotation and at last metal tape 1 is cut into blade.
Fig. 3 is that demonstration has a plurality of metal tape roller unit perspective views that are arranged in the guide roller 52 of roller unit front according to the present invention.
As shown in Figure 3, guide roller 52 comprises a plurality of horizontally-guided roller 52a and a plurality of vertically-guided roller 52b.Guide roller 52 carries in the gap between metal tape 1 guiding two guide pads 2 of roller unit 50 in the future.Roller 52c between horizontally-guided roller 52a flattens the metal tape 1 that carries roller unit 50 by move left and right.Roller 52d above vertically-guided groove 52b flattens the metal tape 1 that carries roller unit 50 by moving up and down.
Fig. 4 is one and shows an opening of being located between two guide pads 2, the removable bridge type mode structure perspective view of cutting.Fig. 5 A and 5B are the profiles that the typical case cuts the bridge mould, and Fig. 6 A and 6B show according to the profile of cutting the shape and the operating mode of bridge mould of the present invention.
As shown in the figure, the bridge mould 21 of cutting of the present invention is spring bias voltages, while is inserted the gathering sill 20a that cuts bridge type mould 20 with every side of every side of the front 21a of mould 21 by the fixing mode of slit 20a is initial, so mould 21 is almost completely avoided undesirable the moving in pattern 20.In view of the above, mould 21 inserts pattern 20 fast and fully.
Under these circumstances, mould 21 slided reposefully in the separated while of the sidewall that is directed to groove 20a, therefore almost completely avoided friction to scratch.So mould 21 high-efficiency long-lifes of the present invention use.
Yet typically cut the bridge mould and have following problem.If typical mould is inserted into when cutting the bridge type mould at first, mould does not have or only has a side to insert the gathering sill 20a of pattern 20, and therefore, when mould inserted pattern 20 fast and fully, the sidewall of mould and groove 20a formed CONTACT WITH FRICTION.
So because CONTACT WITH FRICTION, mould abrades serious or snaps, like this, die life can not be very long.
The bridge type mould 20 of cutting of the present invention is loaded on the device replaceably, cut like this bridge type mould 20 can with other one freely change so that pattern mould 21 and other mould transposing that can make bridge mouth 1a with requirement width.If use a undersized mould with metal tape 1 otch repeatedly by when cutting bridge type mould 20, make on metal tape 1 that to have the bridge mouth 1a that strengthens width be possible at moving metal strip 1 accurately and slightly.
Fig. 7 A is to show to lean on different moulds of the present invention by die-cut process to have along the figure with 1 shape that makes different bridge mouth 1b with 1 sharpening limit to 7C.According to such clicking technique that uses mould 21, a plurality of bridge mouth 1b with preset width form along the sharpening limit with 1.
For example, such one have a bridge mouth 1b be with 1, be preferred on printing material such as ticket and receipt, making line of perforation.Certainly, can in the die-cut process of bridge mouth 1b, adjust the eyelet gap of line of perforation by the die-cut interval of control mould.
Device 100 of the present invention also has a unit that is used for laterally forming a vertical curved groove on a side surface of metal tape.According to a preferred embodiment of the invention, so curved groove 1d can make on a side of metal tape 1 with the emery wheel of a Fig. 8 or the cutter head of a Fig. 9.Below comment the structure and the work of emery wheel and cutter head.
Figure 10 is the plane along the metal tape 1 of a vertical curved groove 1d right-angle bending.Figure 11 is the V-type mouth 1c that a plurality of regular distribution are arranged on the sharpening limit, has shown the perspective view of the metal tape 1 of a V-shaped part among the figure.
As shown in figure 11, a plurality of V-shaped part 1c can make on the sharpening limit of metal tape 1 regularly.A cutting blade that has such V-shaped part 1c is preferred for forming line of perforation on printed matter so that make the line of perforation or the stamp of the V-shaped part 1c perforation that has the regular gap distribution.If the metal tape 1 of band V-shaped part 1c need curve acute angle or obtuse angle, curved groove 1d just immediately and laterally accurately curved with 1 before in the formation of the side of metal tape 1.
Be to form on metal tape 1 so curved groove 1d, it is fixing that metal tape 1 is directed to piece 2 in such a way, be with 1 partly to expose on 2, one motor-driven of guide pad/following actuating cylinder 70 is arranged in the position with the requirement in 1 top, sees Fig. 8.Stepper motor 71 be installed on the piston rod of above-mentioned actuating cylinder 70 and according on the piston rod of above-mentioned actuating cylinder 70/motion starts selectively down.An emery wheel 72 is enclosed within on the driving shaft of stepper motor 71 regularly, is used for being with 1 side laterally to make so curved groove 1d.Above-mentioned emery wheel 72 also is used for making V-shaped part 1c on the sharpening limit of metal tape 1.
On above-mentioned/following actuating cylinder 70 is fixing from the extended supporting pillar of stand one 73 by one, so that along being arranged in guide pad 2 tops well.Cylinder 70 is controlled by control program.
Above-mentioned stepper motor 71 is installed on the piston rod of cylinder 70 with meeting at right angles, and therefore, motor-driven emery wheel 72 is made V-shaped part 1c or made curved groove 1d in its side on the sharpening limit of metal tape 1.
Certainly, such V-shaped part 1c can be made by the pattern (not shown) that has with V-shaped part 10 identical appearance, in order to replace emery wheel 72.Under these circumstances, curved groove 1d can be made by the cutter sweep that separates.
According to another embodiment of the invention, cutter head 74 and last/following actuating cylinder 70 coaxial installations to replace emery wheel 72, are seen Fig. 9.According on the actuating cylinder 70/down motion, above-mentioned cutter head 74 is laterally made a curved groove 1d on the side of metal tape 1.
Before Figure 12 A shows to 12C in the technology, owing to be formed on the mark of the groove in the metal tape bottom so that form a bottom of bending the metal tape of putting and being destroyed gradually on tape.Figure 13 shows one two system mark mold work situations that are used for making a plurality of curved points on two sides of metal tape according to the present invention.
Be perfectly clear as the person skilled in the art, before an artificial bending operation, a system marking procedures is used for making curved point on metal tape 1.That is, if require a metal tape 1 is accurately curved the shape of requirement, bending operation is not to be finished by bending machine but preferably manually finish.
For artificial bending metals band 1, before carrying out bending operation, make a curved point on 1 being with at least.In the former technology, make labeled slots in the bottom of metal tape 1 by a mould, see Figure 12 A, so just make a curved point on 1 being with.Yet in the former technology, a plurality of labeled slots of possibility concentrate on the bottom of metal tape 1 sometimes, see Figure 12 B and 12C, and this make the bottom of metal tape 1 be badly damaged or is out of shape.
Yet this problem is almost made two devices of bending point by the mark mould by Figure 13 of the present invention and is solved fully in each side of metal tape 1.As shown in figure 13, two removable marking mould 80 and 80a that work with actuating cylinder respectively are arranged in the both sides of metal tape 1, in order that directly facing to being with 1.
Two numerical control moulds 80 and 80a by the bias voltage pin respectively bias voltage to metal tape 1.Partially husband's pin is worked with actuating cylinder respectively, and therefore, the both sides with 1 shifted mould 80 and 80a onto fast by the bias voltage pin.Therefore each mark mould 80 and 80a make two curved points in each side of metal tape 1, and do not make metal tape 1 impaired or distortion.
Figure 14 be a demonstration according to the present invention, be used for metal tape 1 is curved the perspective view of the shape of the guiding looper that requires shape.Figure 15 is a plane that shows the looper cross section of Figure 14.Figure 16 is the perspective view that has first gear of looper and pin protection guide pin bushing simultaneously.Figure 17 is the perspective view that shows above-mentioned looper working condition.
Shown in Fig. 2,16,17, an opening, a preferred circular open 12 forms on a position below the curved piece 4 on the stand 10.First gear 33 with a bearing 32 rotatably just in time is installed in opening 12 belows, and is installed in opening 12 tops with the second gear 33a of a bearing 32a, so that relative with first gear 33.
First and second gears 33 and 33a have a cushion hand-hole 33b respectively in the relevant position, and looper 31 inserts the cushion hand-hole 33b of first gear 33 movably.Certainly, pin 31 also inserts the cushion hand-hole 33b of the second gear 33a, is so just maintained movably by two gears 33 and 33a at top and bottom.Pin guider 29 with a semi-circular cross-section and one and corresponding height of width of metal tape 1 is arranged in each cushion hand-hole 33b place.
One or several cushion hand-hole 33b and semi-circular pin guider 29 can be determined according to the quantity of looper 31.Since the size of looper 31 can be according to the curved degree and the wide or high selection of strip material, crooked work can easily be carried out.Preferably use 2 to 4 loopers.
As Figure 14 and the clear finding of Figure 15, looper 31 has roughly semi-circular cross-section of a special graph cross section or, and relative side is protruding and recessed respectively.Above-mentioned looper 31 is arranged in such a way, and promptly pin 31 forms with metal tape 1 with any relative fillet between protruding and the concave surface and contacts.
Each fillet along pin 31 all is shaped on two recess 31a.If contact with metal tape 1 formation at bending operation pin 31, two recesses 31 just are in around the position on the upper and lower limit of metal tape 1, and this just makes fillet closely contact with the side of metal tape 1 in the mid portion formation of two recess 31a.So if when the pin 31 of bending operation rotation is pressed on the metal tape 1, looper 31 can not cause any destruction to the sharpening limit of metal tape 1.
Because above-mentioned recess 31a arranged, looper 31 is just pressed metal tape 1 and equably with respect to being with 1 to be easy to accurate location.
The lower end of looper 31 is connected with the piston of the actuating cylinder 34 that is fixed on first gear, 33 lower ends, so pin 31 can move up by actuating cylinder 34.That is, drive if pin 31 activated cylinder 34, pin 31 is just dashed forward and is inserted the cushion hand-hole 33b of the second gear 33a from opening 12.Looper 31 comes to this and is kept by two gears 33 and 33a securely.
Sometimes, the cushion hand-hole 33b of the second gear 33a may be not and the cushion hand-hole 33b of first gear 33 being aligned accurately.And under such situation, the position of the cushion hand-hole 33b of the second gear 33a needs to adjust, and this point, by suitably reaching at an easy rate to gear-box forward and backward, left or the second gear 33a that moves right.
For looper 31 can be rotated in the opposite direction, first and second gears 33 are connected with the driving wheel 35 or the 35a of reversible stepper motor 30 respectively by a driving-belt with 33a.Therefore two gears 33 can rotate with identical speed in the identical time with 33a.Above-mentioned stepper motor 30 is arranged on the bottom surface of device 100 as mentioned above.Certainly, no matter motor 30 still is an actuating cylinder 34, all works under computer control.
Given when coming by two guide blocks 2 by the band roller unit when metal tape 1, looper 31 rotates with first and second gears 33 and 33a at the curved mouth 4a place of curved piece 4, like this metal tape 1 is curved the shape of requirement.Change the bending direction of metal tape 1 if necessary, looper 31 moves down with respect to metal tape 1 before the position that changes oneself.Thereafter, looper 31 moves up, and contacts with the selected face of metal tape 1 thereby form.
As shown in figure 16, a plurality of loopers 31 are arranged, so that selected at the bent angle of metal tape 1 and the wide and high looper 31 that is fit to.That is, require shape for the top from curved mouth 4 curves metal tape 1, first looper 31 with appropriate size is chosen and move to implement bending operation in the upper vertical of curved mouth 4.After first looper 31 moved down, one second looper (not shown) or one the 3rd looper (not shown) were chosen, under the control of predefined computer program, with the 31 same way as work of first looper.
Under these circumstances, be located at movably on the device 100, so can regulate the gap (a) of bending between piece 4 and the looper 31 according to the thickness of metal tape 1 owing to bend piece 4.For example, index zone is thin if metal tape 1 compares, and curved piece 4 just moves forward, thereby reduces the gap (a) between curved piece 4 and the pin 31.On the contrary, the standard tape thickness if metal tape 1 compares, curved piece 4 just moves backward, thereby increases the gap.This motion that curved piece 4 is regulated gap (a) is easy to find out from Figure 18 and 19.
Figure 20 shows solid band device that is respectively applied for fixing and cutting metal band and the front view of swinging the device of cutter.Figure 21 shows admittedly with the view of device with the work of swing cutter.
Shift to the front portion of stand 10 continuously through the metal tape 1 of bending process.Under these circumstances, swing cutter 43 moves to the cutting position that a cutter 43 is cut into metal tape 1 requirement of blade.Be positioned at the above-mentioned swing cutter 43 of curved piece 4 fronts, be hinged on the movable carriage 40 and rotationally and fixed by movable carriage 40.Above-mentioned carriage 40 is fixing slidably and work with first actuating cylinder 41 by two vertical guide rails 11 two side edge, like this, vertically slides selectively along two guide rails 11 in relative direction.
The dismantled and assembled device 42 of being with admittedly that is used for fixing metal tape 1 is arranged in the bottom of carriage 40.Figure 23 and 24 respectively above-mentioned admittedly with the perspective view and the cross-sectional view of device 42.
The above-mentioned device 42 of being with admittedly comprises two blocks, and these two blocks are of similar shape and when two blocks unite two into one, form a solid trough of belt 42a between two blocks.The above-mentioned width that is designed to consolidate according to the thickness adjustment of metal tape 1 trough of belt 42a admittedly with device 42.
That is, admittedly form by the gap between two block inner surfaces with the solid trough of belt 42a of device 42.
Gu inner end or the belly of trough of belt 42a are V-shaped, can fixedly secure the sharpening limit of metal tape 1 like this but can not cause any damage it.Above-mentionedly be with device 42 and curved piece 4 admittedly both form an external member, in order that be with device 42 to change together admittedly with curved piece 4.
Gu there is chamfering on the inlet limit of trough of belt 42a, in order that even from curved mouth 4a be with 1 not with groove 42a accurately during being aligned, and also can with metal tape 1 effectively lead-in groove 42a do not slip up.
Under these circumstances, swing cutter 43 is rotated by second actuating cylinder 44, temporarily like this is maintained at cutting action holding fix of solid band device 42 1 sides and moves down with carriage 40, sees Figure 27 A and 27B.Under these circumstances, thus the displaceable member 48 that is arranged in groove 45 fronts of stand 10 moves horizontally the lower end of the swing cutter 43 that is fixed on locked groove 47.
The swing cutter 43 that is fixedly secured by the locked groove 47 of displaceable member 48 is cutting metal band 1 accurately.That is, will be with 1 to cut into cutting blade if desired, displaceable member 48 just activated cylinder and drives, and therefore, part 48 slides in gathering sill 46 along relative direction and causes well and accurately cutting metal band 1 of swing cutter 43.Certainly, swing cutter 43 can one near or the control of sliding electric transducer under be moved to the bending operation holding fix, this sensor is verified the portion that finally is bent of metal tape 1 advising before cylinder sends enabling signal to being used for causing of cutter 43.
Figure 25 and 26 shows that the present invention swings the view of cutter 43 shapes.As shown in the figure, the bottom of cutter 43 narrows down at the middle part that has an inclined cut face 43a, forms an eel-like figure thus.It is oblique that above-mentioned cut surface 43a presses the β angle lapping.Thereby when swing cutter 43 when being rotated cutting metal band 1, cutter 43 at first contacts with the bottom of metal tape 1 with cut surface 43a, thus cutter 43 from 1 bottom to top cutting metal band 1.So swing cutter 43 vertical cut metal tapes 1 are accurate.
That is, if metal tape 1 is cut from the top to the bottom by the swing cutter, just be with admittedly on the device 42 by the cutting force biased downward of swing cutter 43 with 1, the result is with device 42 firmly not maintain admittedly and is with 1, is with 1 by unexpected and oblique cutting and this makes.,, be with 1 therebetween, therefore be with device 42 to fix admittedly more firmly with regard to the bias voltage that makes progress if metal tape 1 is cut from the bottom to the top by swing cutter 43 as mentioned above, and simultaneously by accurate vertical cut.
Figure 28 shows that two or more are produced by device of the present invention, places the view of the cutting blade on the flat plank.The sharpening limit of blade 1 as shown in the figure,, two or more cutting blades places on the plank, owing to just can form the gap in the junction of 1 of cutting blade if being right after by the right angle mutually with blade end together.That is, might form the gap between the inclined plane on the sharpening limit of a blade end and another blade.Such gap can reduce the cut quality of cutting blade, therefore need eliminate such gap from placing the cutting blade on the plank.
For eliminating such gap from the junction between cutting blade, the end of the cutting blade 1 that end is connected with the side of another blade 1 is accurately processed so that make the end on the inclined plane on the actual sharpening limit that can satisfy other blade 1.So, place any gap of 1 junction of cutting blade on the plank to be eliminated usually.
As mentioned above, the invention provides a kind of device of printed matter that be used to make with cutting blade.No matter blade shaped device metal tape size of the present invention is by associated working, by suitably crooked and the blade that metal tape cuts into requirement made cutting blade.Device also has replaceable mold, therefore can make the bridge mouth with different spacing and shape.Device has a vertically moving looper and a swing cutter.Looper can curve metal tape the shape of requirement fast, and the swing cutter cuts into cutting blade with metal tape like clockwork.
Therefore other advantage of the present invention is, installs quick production high accuracy cutting blade, has improved production efficiency and has reduced the cost of cutting blade.
Although the preferred embodiments of the present invention have been owing to the reason that illustrates is revealed, the person skilled in the art knows, under situation about not breaking away from as the said scope and spirit of the present invention of claims, multiple improvement, to replenish and replace all be possible.
