Therefore, highly flexible and efficient automated stamping equipment has become the main trend in the development of sheet metal forming equipment; There are still the following defects in specific use: 1. During the manufacturing process, if the metal plate has poor grip, it is easy to slide or shift during the cutting, stamping, bending and other processes, resulting in reduced processing accuracy and affecting the size and shape accuracy of the product. At the same time, poor grip may cause scratches, indentations or deformation of the metal plate during processing, affecting the appearance quality and performance of the product.

[0022] The complete working principle and steps of the above embodiment are as follows: Initial qualification: Figure 1 As shown, the operator feeds the metal plate or strip into the working area of ​​the punching machine 1, usually through an automatic feeding system. Then, the punching machine 1 fixes the metal plate inside the die table 214 through a clamp or a clamping device to ensure that it does not move during the punching process. Next, the controller 13 is started to drive the punching machine 1 to move downward and press down through the pressure plate 11 to apply pressure to the metal plate to complete cutting, forming or other punching operations. In addition, the lower die table 12 inside the punching machine 1 is usually matched with the upper die table 14 to realize the specific operation of punching, which determines the shape and size of the punching. When using: Auxiliary engraving mechanism used as a positioning reference mark during production and assembly 2 steps: like Figure 3 to Figure 4As shown, when the punching machine 1 is in the process of pressing downward through the pressure plate 11, since the lower end of the pressure plate 11 is fixedly connected to the upper die table 14, and the external plate 21 is fixedly connected to the outer wall of the upper die table 14, the downward movement of the pressure plate 11 will synchronously drive the external plate 21 to move downward, and then the convex shaft 23 engaged in the arc groove opened inside the external plate 21 will be pushed by the external plate 21 to move downward, so that the slider 22 fixedly connected to the outer wall of one side of the convex shaft 23 will be pulled downward together, thereby rotating the convex shaft 23 away from the slider 2 The transfer rod 24 on the outer wall of one side will deflect downward, and the downward deflection of the transfer rod 24 will drive the longitudinal bevel gear 25 fixedly connected to one end of the transfer rod 24 to rotate, so the longitudinal bevel gear 25 meshing with the transfer rod 24 will rotate along with the rotation of the transfer rod 24, and the sleeve shaft 28 fixedly connected to one side of the transverse bevel gear 27 will rotate along with the rotation of the transverse bevel gear 27, and the outer sleeve plate 29 connected to the outer wall of the sleeve shaft 28 and the slide plate 210 slidably connected to one end of the outer sleeve plate 29 and the upper end of the slide plate 210 are fixedly connected The engraving rod 211 will rotate along with the rotation of the transverse bevel gear 27, so the barrier rod 216 fixedly connected to the bottom end of the engraving rod 211 will also rotate together, so that the rotation of the engraving rod 211 will make the end of the engraving rod 211 that is in contact with the outer wall of the mold table 214 move in a circular track to engrave the outer wall surface of the mold table 214, and the outer wall of the mold table 214 is provided with a square opening, so the circular track movement of the engraving rod 211 can indirectly engrave the outer wall surface of the metal plate of the mechanical parts placed in the mold table 214. The upper end of the connecting plate 29 is also fixedly connected with the longitudinal bevel gear 25, and the end of the connecting block 215 away from the external connecting plate 29 abuts against the inner wall of the diamond guide plate 213, and when the external connecting plate 29 rotates, the end of the connecting block 215 away from the external connecting plate 29 will slide along the inner wall of the diamond guide plate 213, and when sliding to the angle of the diamond guide plate 213, it will push the slide plate 210 to move inside the external connecting plate 29, so as to play a positioning and guiding role for the outer wall of the metal plate of the mechanical parts placed inside the engraving rod 211 engraving the mold table 214; Edge tapping mechanism for locally heating and softening metal edges by tapping 3 steps: like Figures 5 and 6As shown, when the engraving rod 211 rotates until the obstacle rod 216 contacts the outer wall of the connecting plate 35, since the obstacle rod 216 and the connecting plate 35 are at the same level, the rotation of the engraving rod 211 will cause the obstacle rod 216 to push the connecting plate 35 to drive the outer connecting rod 34 to deflect downward, and then the deflection of the outer connecting rod 34 will drive the obstacle wheel 33 connected to one side of the outer connecting rod 34 to rotate clockwise, so that the clockwise rotation of the obstacle wheel 33 will cause one end of the obstacle wheel 33 to push the outer wall of the inner connecting rod 37 that contacts, so that the inner connecting rod 37 drives the rotating block 3 6 deflects downward, so that the hammer block 38 fixedly connected at one end of the rotating block 36 deflects upward, until the obstacle rod 216 rotates to leave the outer wall surface of the connecting plate 35 that is in conflict, and the obstacle wheel 33 rotates to the outer wall away from the inner connecting rod 37, so that the rotating block 36 deflected downward will reset upward, and the hammer block 38 will deflect downward and reset, and then knock the outer wall surface of the diamond guide plate 213, so that the edge of the metal plate of the mechanical accessory clamped in the diamond guide plate 213 can be knocked by the reciprocating deflection of the hammer block 38; Apply friction at the clamping point to more accurately position the metal plate. 4 steps: like Figures 7 and 8 As shown, when the engraving rod 211 is attached to one end of the outer wall of the mold table 214 to perform a circular trajectory movement to engrave the outer wall surface of the mold table 214, the L-shaped push plate 41 fixedly connected to the outer wall of one end of the engraving rod 211 will be pushed to slide on the outer wall of the diamond guide plate 213, and then the pulley 48 that passes through the L-shaped push plate 41 and is fixedly connected to one side of the camshaft 45 will slide on the surface of the friction shaft 49 as the L-shaped push plate 41 moves. As a result, the movement of the pulley 48 will rub the friction shaft 49 to make the friction shaft 49 rotate counterclockwise, thereby rubbing the clamping point of the metal plate of the mechanical accessory clamped into the diamond guide plate 213. In addition, when the L-shaped push plate 41 moves to the diamond guide plate 213 When the camshaft 45 is at the angle, the turning of the L-shaped push plate 41 will cause the camshaft 45 to deflect until the short-circuit block 46 contacts the inner wall of the fixed column 47, and then the camshaft 45 squeezes the protrusion 43, so that the protrusion 43 moves to the side away from the camshaft 45 and squeezes the spring 44, and then the deflection and turning of the camshaft 45 will cause the rotation direction of the pulley 48 fixed at the lower end to deflect together, so that the pulley 48 moves and rubs on the surface of the friction shaft 49, causing the friction shaft 49 to rotate clockwise. In summary, the deflection and rotation of the pulley 48 and the friction with the friction shaft 49 cause the friction shaft 49 to rotate, so as to rub the clamping point surface of the metal plate of the mechanical accessory, thereby providing flexibility in adjusting the friction force; Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
