[0004] The above technology can effectively solve a series of problems such as the hole is too small to complete the punching and edge collapse, and the size is unstable, and can ensure a higher hole position and shape accuracy. However, after the punching and bending of the workpiece are completed, the mold will directly push the finished workpiece to the ground. The collision between the workpiece and the ground will cause a certain degree of dents and wear on the surface, so innovation is made in this technology. Summary of the invention

[0005] The purpose of the present invention is to provide a continuous punching die to solve the problem that the die proposed in the above background technology will directly push the finished workpiece to the ground, and the collision between the workpiece and the ground will cause a certain degree of dents and wear on the surface.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. A continuous punching and cutting die of the present invention is provided with a telescopic column, an inclined frame, a roller, an auxiliary sleeve rod, a limiting rod and a protective plate. The inclined frame is always at a specific angle. After the workpiece is pushed to the surface of multiple rollers by the stamping upper die, the multiple rollers rotate continuously, thereby accelerating the sliding speed of the workpiece, and the workpiece will move to the inside of the collection box with inertia. Since the sponge pad is made of sponge, the surface is relatively soft. Therefore, after the workpiece collides with the surface of the sponge pad, it will not cause wear to the surface of the workpiece, and a downward force is applied to the protective plate, thereby driving the multiple auxiliary sleeve rods to move downward at one end of the support column, so that the shielding height of the protective plate can be adjusted according to the thickness of the workpiece, and one end of the limiting rod is embedded into the inside of the corresponding circular hole for threaded connection, so that the support column and the auxiliary sleeve rod can be limited and fixed.

The top of a collection box is connected to the bottom of the abutment plate by a plurality of springs. As the number of workpieces stored in the collection box increases, the height of the collection box will gradually decrease, and the bottom of the collection box will gradually press the plurality of silicone strips. The silicone strips will gradually deform after being subjected to force, thereby preventing the bottom of the collection box from being directly squeezed against the top of the shelf.

Since the sponge pad 17 is made of sponge, its surface is relatively soft. Therefore, after the workpiece collides with the surface of the sponge pad 17, it will not cause wear to the surface of the workpiece, and a downward force is applied to the protective plate 13, thereby driving the plurality of auxiliary sleeve rods 11 to move downward at one end of the support column 9. Embodiment 2:

[0020] Based on the first embodiment, Figure 1 and Figure 4 As shown, the positions of the multiple circular holes 10 are arranged at equal intervals, and the two limit rods 12 are respectively threadedly connected to the multiple circular holes 10. Two abutment plates 14 are fixedly installed on one side of the stamping lower mold 1, and the bottom ends of the two abutment plates 14 are fixedly installed with multiple springs 15, and one end of the multiple springs 15 is fixedly installed with a collection box 16, and a sponge pad 17 is placed inside the collection box 16. A shelf 18 is fixedly installed at the bottom ends of the two abutment plates 14. The present invention provides a continuous punching mold, by arranging abutment plates 14, springs 15, sponge pads 17, shelf racks 18 and silicone strips 19, the top end of the collection box 16 is connected to the bottom end of the abutment plate 14 through multiple springs 15, and as the number of workpieces stored in the collection box 16 increases, the height of the collection box 16 will gradually decrease.

[0021] Working principle: the workpieces that need to be continuously stamped are placed on the surface of the stamping lower die 1 in turn. When the workpiece moves, the stamping upper die 2 will gradually lower, so that the surface of the workpiece can be stamped. The stamping lower die 1 and the stamping upper die 2 are continuously punched and cut, and the workpiece can be moved to the bending position. The stamping upper die 2 can not only stamp the next workpiece, but also bend the previous workpiece, and can continuously process the workpiece, saving time and effort. The tilting frame 7 is always at a specific angle. After the workpiece is pushed to the surface of multiple rollers 8 by the stamping upper die 2, the multiple rollers 8 rotate continuously, so as to speed up the sliding speed of the workpiece. The workpiece will move to the inside of the collection box 16 with inertia. Since the sponge pad 17 is made of sponge, its surface is relatively soft. Therefore, after the workpiece collides with the surface of the sponge pad 17, it will not be The surface of the workpiece is worn, which increases the service life of the workpiece. A downward force is applied to the protective plate 13, which will drive multiple auxiliary sleeve rods 11 to move downward at one end of the support column 9, so that the shielding height of the protective plate 13 can be adjusted according to the thickness of the workpiece. One end of the limiting rod 12 is embedded in the corresponding circular hole 10 for threaded connection, so that the support column 9 and the auxiliary sleeve rod 11 can be limited and fixed. The top of the collection box 16 is connected to the bottom of the abutment plate 14 by multiple springs 15, and as the number of workpieces stored in the collection box 16 increases, the height of the collection box 16 will gradually decrease, and the bottom of the collection box 16 will gradually press the multiple silicone strips 19. The silicone strips 19 will gradually deform after being subjected to force, thereby avoiding the bottom of the collection box 16 directly squeezing the top of the shelf 18.
