15 Claims. l
Ihis invention relates to Ia machine for bending rods, wire and simi-lar sections, and particularly, for example, lead-in wire for vacuum tubes.
It -is an object of the invention to provide a machine for simultaneously producing a double bend in a rod or wire by means of a machine having a double slide of which one slide is mov able in one direction and the other is movable in a direction at right angles thereto. A further object of the -invention resides in the provision of a connecting link pivotally secured to one of the slides to exert a pull thereon at an angle to the movements of yboth slides. Another object resides in the provision of meansto' heat, preferably by electr-ic resistance, and before the bending operation, that part of the wire which is to be bent.
The machine thus aims to provide a slide which is so mounted that it is capable o f moving either in -a vertical or horizontal direction or both, or at any Yangle determined by the desired bend to be imparted in the rod. Another object resides in the provision of means -for adjusting the extent of movement of the slides.
Further objects will lie-apparent from the following description when considered in connection with the accompanying drawings in which,
Figure l is la planview of the wire bending machine showing the `position of the parts just before' the bending operation,
Fig. 2 is a plan view ofthe machine showing the position .of the parts after completion of the bending operation,
Fig. 3 -is a cross Asectional view of the machine taken yon li-neV 3 3 of Fig. `1 -in the direction of the arrows, and
Fig. 4 is -a cross .sectional View oi the machine taken' on line 4 4 of Fig. 1in the direction of the arrows.
The -nfachi-ne illustrated by way of example includes -a base frame or plate `I having a square or rectangular slidewayy provided therein de-v ned by side faces -or surfaces |2 Vand |3. The base frame has a pair of upstanding lugs I4, one adjacent each side vface `|12 and each lug has a threaded `hole thereinetoreceive adjustable stop bolts I5 andl6, the purpose -of Awhich will A.be explained.
Ay rectangular mai-nslideplate or member Il is slida-bly mounted in the slideway E|| -in the di'- rection of the arrows and guided by the side faces II3. AsFWill 'be .seen Vlfrom Figs. l and 2, the vslidevplate |-1 has alength rvjustsufiicient-to contact `the side iaces lf3 but #the Vwidth is narrower than the length-of the vfaces iI3 soA that 55 2 the slide plate will reciprocate from right to left and Vice versa toward the faces |'2. lhe slide plate is provided with a rectangular lslideway i8 defined by side faces or surfaces I3 and and this slideway I8 is provided with an auxiliary slide plate or member 2|. The `slide plate 2| is slideble in the diregten ,Qf .the err-,WS which is at right angles relative to the reciproeating movement of the slide plate Ifl and such sliding movement is guided by the side faces 29 toward the side faces |9.
An adjustable stop -bolt 2'2 is threaded in the slide plate ll against which the slide plate 2| abuts during the bending operation.
The slide plate 2| i s provided with a pivot pin 23 to which a connecting link 24 is secured which operates the slide plates. This linl; has one en d of the spring 25 secured thereto by p in 26, the other end of the spring being secured to a 21 secured in the base frame |0. YrPhe slide plate 2| is also provided with a pair of clamping jaws 28 and -2 9`of which jaw 28 is stationary but jaw 29 is slidable in a slot 30. A cam 3| contacts the jaw -29 to adjust it against the work and thus securely hold the work between the jaws.
Another pair of clamping jaws -32 and 33 are mounted on the base yframe I0 of which jaw 32 is stationary but jaw 33 Yis slidable in a slot 34. vA. cam 35 is pivotally mounted to adjust the jaw 33 toward the work to thereby clamp thev Work between the jaws.
On the drawings the work is indicated by a wire or rod 36 which is clamped in the jaws 28, 29, 3 2 and 33. In o rder to lprovide for the resistance heating of ythe rod 36 in its length -be-l tween the jaws, the latter are suitably insulated from each other and from the frame |0 and slides |f| and 2| and the rod may also be linsulated by any suitable means such as an insulation s trip, not shown, provided under the wire and on the parts of the machine. Wires 3l and 38 carry electric current to the jaws -23 and 3 2, the latter of which are preferably made of copper` The machine operates as follows:
'The wire 38 is clamped between both jaws' 28, 29 and 32, 33 by means `of vthe cams 3| and 35 to lhold the wire securely in the machine. The electric current is then turned on by any suitable switch, not shown, toheat vthe wire by resistance in vthat portion of its length which'isbetween the jaws and which is to be bent. After heating the wire to a desired degree, such for instance where it becomes almose incandescent, theconnecting link 24 isy pulled in the direction indi-v cated `by its arrow, by means of a pneumaticV plunger, not shown, whereby the jaws 28 and 29 are moved relative to the jaws 32 and 33. Both slides |1 and 2| may move simultaneously in the direction indicated by their arrows at right angles relative to each other or the auxiliary slide 2| may move rst until its abuts against the stop bolt 22 and then the slide plate moves to the left until it abuts against the stop bolt I6. Thus when slide 2| moves rst and then slide the movement of slide 2| determines the 01T- set in the wire. Furthermore the slide 2| is capable of moving either vertically or horizontally or at any angle determined by the desired bend in the rod. 1
The duration of the heating time for the rod 36 may be controlled by a time switch, not shown, and the time switch in turn may operate the pneumatic plunger for the link 24 to produce the bending operation.
After the bending operation, Fig. 2, the wire is removed from the machine by operation of the cams 3| and 35 and the spring 25 will move the parts back to the initial position shown in Fig. 1.
The machine is of course capable of various modifications within the scope of the invention and the appended claims. For instance the slides I1 and 2| may have any desired thickness and both sli-des may have the same thickness so that the slide 2| will contact the surface of the slideway It would also be possible to provide the slideways and |8 and the slides with tongue and groove slide surfaces in order to `securely maintain the parts in their working positions during the bending operation.
