The specific embodiment
Among Fig. 1, but slide block 3 easy on and off that are arranged on the framework 2 of punching machine 1 move, bolster 4 is fixed on the framework 2 of slide block 3.A vibration proof device 5 is fixed to the bottom side of framework 2, is used for the vibration and the plant bottom case of punching machine are kept apart.
Among Fig. 2, crank axle 8 is by framework 2 supportings.Crank axle 8 is rotatably mounted by the bearing that is arranged in the framework 2, and is arranged on the fore-and-aft direction with respect to framework 2.
A master gear 9 is fixed on the crank axle 8.On the other hand, flywheel 11 can be rotatably set in the framework 2.Flywheel 11 comprises a clutch-brake, and drives rotation by a motor (not shown).A pinion 10 forms on the axle that above-mentioned clutch-brake is set thereon.Pinion 10 and above-mentioned master gear 9 engagements.
With reference to Fig. 3 and Fig. 4 to regulating element 12 and make more detailed description on every side.Fig. 3 is similar to Fig. 4, and difference is that it is a perspective view.Slide block 3 only partly is shown among Fig. 3.It is the system of 180 degree that degree in crank angle all is shown in these accompanying drawings, and slide block 3 is positioned at bottom dead center.
Slide block guide mechanism 6 and position adjusting mechanism 7 are wholely set.Slide mechanism 6 is arranged on regulating element 12 tops, and position adjusting mechanism 7 is arranged on regulating element 12 belows.Regulating element 12 is covered by lid 13, and lid 13 is fixing by dividing plate 15 usefulness bolts 14.Regulating element 12, dividing plate 15,15 and cover 13 and constituted the framework that a space is arranged at the middle part.
Above-mentioned space holds the eccentric part 8a of crank axle 8, a upper slips 16 and a bottom sliding part 17.Upper slips 16 and bottom sliding part 17 cooperate with eccentric part 8 with the below respectively up, and upper slips 16 is free to slide on lid 13, and bottom sliding part 17 is free to slide on regulating element 12.Slide block guide mechanism 6 comprises upper slips 16, bottom sliding part 17, regulating element 12, lid 13, dividing plate 15 etc.
A threaded rod 12a is formed on the bottom of regulating element 12.A nut 21 is fixed on this threaded rod 12a.Nut 21 is packed in the slide block 13 by this way, and it can rotate freely, but constrains in vertical direction.Keeper 22 of nut 21 usefulness remains on the slide block 3.
A worm gear 20 is formed on nut 21 outsides.Worm gear 20 and worm screw 19 engagements that are rotatably provided in the slide block 3.Worm screw 19 is driven by a motor (not shown).Threaded rod 12a, nut 21, worm gear 20, worm screw 19 etc. have constituted position adjusting mechanism 7, and it is corresponding to the slidable adjustment mechanism of routine.
What the position adjusting mechanism 7 of present embodiment used is screw mechanism, but also can be made of hydraulic mechanism.In other words, it can be constructed like this, and a hydraulic cylinder is provided below regulating element 12, thereby moves regulating element 12 by regulating oil mass with respect to slide block 13.Replacedly, a circular cone can be set below regulating element 12, thereby move regulating element 12 with respect to slide block 13.
Among Fig. 4, when worm screw 19 rotations, worm gear 20 and nut 21 rotations promote regulating element 12 up and down by bolt mechanism.Thereby regulating element 12 can move forward and backward with respect to slide block 13.
Prevent regulating element 12 unexpected rotations by a guiding device.In other words, above-mentioned guiding device has such function, prevents that the rotation owing to regulating element 12 causes the slidable adjustment amount to change in the pressing operation process.
In Fig. 4 and Fig. 5, piece 27 is configured among the guide hole 3a of slide block 13.Piece 27 is fixed on the slide block 3 by cam pin 28 and bolt 29.Ball type device 26 is between piece 27 and regulating element 12.Ball type device 26 comprises a spherical member and a flat component, and forms the part of ball.The height of ball type device 26 is approximately 3% of bulb diameter.Ball type device 26 is stored in the spherical chamber that is arranged in the regulating element 12, and above-mentioned plane surface contacts with piece 27.Piece 27 has a guiding face.
In the present embodiment, the angle [alpha] that the contact surface between piece 27 and a pair of spherical 26 the plane surface forms is 120 degree.As seeing that from piece 27 1 sides angle is protruding.This angle is selected on the eccentrically loaded basis that acts on the regulating element 12.It is based on following hypothesis and selects: the eccentric load of left and right directions is greater than fore-and-aft direction.If α is 120 degree, then because triangle relation, the ratio of above-mentioned projected area is (3) 1/2: 1, in other words, and about 1.7: 1.
The position of piece 27 can be regulated at fore-and-aft direction (axial direction of the eccentric part 8a of crank axle 8) by cam pin 28.Piece 27 is regulated, thereby the guiding face of regulating element 12 is regulated with respect to the inclination angle of slide down moving part 16 and 17 (particularly sliding part 17) at fore-and-aft direction.In other words, the outer periphery of guaranteeing the eccentric part 8a of crank axle 3 is distinguished surperficial the contact with the interior periphery of bottom sliding part 17 and the bottom surface of bottom sliding part 17.
Because regulating element 12 is fixed on the slide block 3 by threaded rod 12a, the correspondingly swing of horizontal plane (end face) that makes regulating element 12 is regulated in the front and back of piece 27.
Among Fig. 9, the cylindrical parts that is positioned at cam pin 28 left end is with respect to the eccentric amount " E " of the cylindrical parts that is positioned at the center.By unclamping bolt 29 slightly, with special tool(s) with reverse hole 35 and join and be incorporated in the arrow B direction and rotate cam pin 28, piece 27 moves at direction A, after having regulated piece 27, bolts on 29, and piece 27 is fixed on the slide block 13.
Shown in Fig. 6 corresponding to another embodiment of above-mentioned Fig. 5.Under the situation of Fig. 5, the guiding face angulation α of a pair of ball type device 26, this angle [alpha] sees it is protruding from piece 27 1 sides.On the other hand, the angle beta corresponding to angle [alpha] sees it is protruding from piece 30 and 31 1 sides among Fig. 6.As a result, the cross sectional shape of regulating element 12 ' is protruding towards piece 30 and 31.The same with the situation of piece 27, piece 30 and 31 can be regulated by a cam pin 28.
Fig. 7 illustrates other embodiment that ball type device 26 is had different assembly models with Fig. 8.Under the situation of Fig. 7, a receiving element 32 is arranged on the regulating element 12, and receiving element 32 receives ball type device 26.In other words, receiving element 32 is between ball type device 26 and regulating element 12.Receiving element 32 is fixed on the regulating element 12 by bolt 33.By this structure, needn't on regulating element 12, form the spherical surface of a depression, and make its manufacturing easier.
Under the situation in Fig. 8, lid 34 is positioned on the ball type device 26 ', and allow to cover 34 and piece 27 relative to each other slide.Lid 34 spherical surfaces with a projection that cooperates with the spherical surface of ball type device 26 '.Ball type device 26 ' is fixed on the regulating element 12 by bolt 33.Ball 26 ' is arranged in regulating element 12.
The invention effect
The present invention becomes the element corresponding to coupling bar and there is no need, thereby can be higher The position arranges slide block. So just shortened the height of punching machine. Consider this point, hanging down Nogata to rigidity also increased, the rigidity of horizontal direction has also increased. Can also reduce like this The height that holds the building of punching machine, and the operation of improvement forcing press. In addition, because Regulating element 12 is by a more rational guide member guiding, and the present invention also provides a kind of to have more Stability and more long-life punching machine.
