In domestic production, stamping technology is increasingly used due to its advantages over traditional machining, including material and energy conservation, high efficiency, low operator skill requirements, and the ability to create products that are not possible through the use of various molds. Stamping production primarily targets sheet metal. Using molds, it can produce blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting, and extrusion, among other applications, with wide application across various fields. The stamping process requires the design of a punch and die tailored to the desired part's structure. The punch and die work together to produce the desired part, and then remove the stamped part to ensure a continuous stamping process.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4 A punching machine that can reduce burrs on a tearing surface includes a workbench 1, an L-shaped connecting plate 2 is installed on the workbench 1, a stamping mechanism 3 is installed on the L-shaped connecting plate 2, a stamping material 4 is placed on the workbench 1, and the stamping material 4 is located directly below the stamping mechanism 3. A stamping hole 5 is opened on the workbench 1, and a grinding layer 6 is provided on the inner wall of the stamping hole 5. An L-shaped supporting plate 7 is slidably connected to the bottom of the workbench 1, and a transmission motor 8 is installed at the bottom of the L-shaped support plate 7. A rotating seat 9 is connected to the output shaft of the transmission motor 8. The rotating seat 9 is located at the top of the L-shaped support plate 7 and corresponds to the position of the stamping hole 5.

[0021] When the device is in use, the stamping material 4 is stamped through the stamping mechanism 3. The bottom of the mold formed after stamping is located on the rotating seat 9, and the position above the bottom is in the stamping hole 5. Then the transmission motor 8 is started, and the transmission motor 8 drives the rotating seat 9 to rotate, so that the mold rotates synchronously, causing the position where the mold contacts the grinding layer 6 on the stamping hole 5 to repeatedly rub, thereby achieving the purpose of grinding the cut surface of the mold edge to reduce burrs. The device is simple to operate and occupies a small area. It can grind the mold while stamping it, and can effectively process the burrs at the edge of the mold, further improving the stamping effect and reducing production costs.

[0022] Specifically, in this embodiment, a bidirectional screw rod 11 is rotatably installed on the rotating seat 9, one end of the bidirectional screw rod 11 is located outside the rotating seat 9 and is connected to the output end of the servo motor 12, and the servo motor 12 is installed on the side wall of the rotating seat 9. Both ends of the bidirectional screw rod 11 are threadedly connected to clamping blocks 13, and the two clamping blocks 13 are arranged opposite to each other, so that after the mold formed after stamping falls on the rotating seat 9, the operation of the servo motor 12 can drive the two clamping blocks 13 to approach the mold and confine it to the rotating seat 9, so that when the rotating seat 9 rotates, it can drive the mold to rotate synchronously, which facilitates repeated friction between the mold and the grinding layer 6.

[0023] Specifically, in this embodiment, a mounting groove 10 is opened on the rotating seat 9, and the bidirectional screw rod 11 is rotatably installed on the mounting groove 10, so that the bidirectional screw rod 11 can be rotatably installed inside the rotating seat 9 through the mounting groove 10, thereby reducing the distance between the rotating seat 9 and the bottom of the workbench 1, and further increasing the contact area between the mold after stamping and the stamping hole 5.

[0024] Specifically, in this embodiment, a cylinder 14 is installed on the bottom wall of the workbench 1, and the output shaft of the cylinder 14 is connected to the L-shaped support plate 7, so that when the cylinder 14 is running, it can drive the L-shaped support plate 7 to slide on the workbench 1, thereby completing the polishing of the mold after stamping and the unloading of the mold after polishing by moving the position of the L-shaped support plate 7 on the workbench 1.

[0025] Specifically, in this embodiment, a combination plate 15 is installed on the lower wall surface of the workbench 1, and the combination plate 15 is adapted to the end close to the L-shaped support plate 7, so that the L-shaped support plate 7 can be movably connected with the combination plate 15 when it moves toward the combination plate 15, thereby providing partial support for the L-shaped support plate 7 through the combination plate 15, thereby improving the stability of the L-shaped support plate 7.

[0026] Specifically, in this embodiment, a barrier strip 16 is installed on the bottom wall of the workbench 1. The barrier strip 16 is located on the side of the outer periphery of the punching hole 5 close to the servo motor 12, and the barrier strip 16 does not contact the upper surface of the clamping block 13. When the L-shaped support plate 7 moves toward the end away from the combination plate 15, it drives the post-stamping mold located thereon to move synchronously. When the mold contacts the barrier strip 16, the mold is restricted by the barrier strip 16 and cannot move. The L-shaped support plate 7 is in a normal moving state, so that the mold is removed from the L-shaped support plate 7, thereby completing the unloading work of the mold.

[0027] Specifically, in this embodiment, a slide groove 17 is opened on the bottom wall of the workbench 1, and a connecting block 18 is installed on the top of the L-shaped support plate 7. The connecting block 18 is adapted to the slide groove 17, so that the L-shaped support plate 7 can be slidably connected to the workbench 1 through the adaptability of the connecting block 18 and the slide groove 17. At the same time, the L-shaped support plate 7 can only move along the direction of the slide groove 17, thereby avoiding displacement of the L-shaped support plate 7 when moving.

[0028] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
