Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1-4 shown, the present utility model provides a technical solution: including a mold assembly 1, an automatic centering assembly 2 is arranged at the inner bottom of the mold assembly 1. The mold assembly 1 includes a bottom plate 101, an L-shaped plate 102 is fixedly installed on the back of the bottom plate 101, and a lower mold 105 is fixedly installed at the front edge of the top surface of the bottom plate 101;

[0021] The automatic centering assembly 2 includes a mounting plate 201. Side plates 202 are fixedly installed at the edges on both sides of the front surface of the mounting plate 201. A round shaft 203 is fixedly installed between the front ends of the two side plates 202. Sliders 204 are slidably sleeved at both ends of the shaft body of the round shaft 203. Centering plates 205 are fixedly installed on the front surfaces of the two sliders 204. Chute grooves 206 are formed on the opposite surfaces of the two side plates 202. Slide rods 207 are slidably installed in the two chute grooves 206. A moving plate 208 is fixedly installed between the two slide rods 207. Two first rotating seats 209 are fixedly installed in the middle of the front surface of the moving plate 208. Transmission rods 210 are rotatably connected to the front surfaces of the two first rotating seats 209. The other ends of the two transmission rods 210 are rotatably installed with second rotating seats 211. The two second rotating seats 211 correspond to the two sliders 204 one by one. The second rotating seats 211 are fixedly installed on the back surfaces of the sliders 204. A linear motor 212 is fixedly installed on the bottom surface of the mounting plate 201.

[0022] In this embodiment, the slider of the linear motor 212 is fixedly connected to the bottom surface of the moving plate 208. The two centering plates 205 and the two transmission rods 210 are both symmetrically arranged. The linear motor 212 can drive the moving plate 208 to move. The movement of the moving plate 208 can drive the two first rotating seats 209 to move. The movement of the two first rotating seats 209 can drive one ends of the two transmission rods 210 to move. The movement of one ends of the two transmission rods 210 can drive the second rotating seats 211 and the sliders 204 at the other ends to move on the slide rods 207. By controlling the synchronous movement of the two sliders 204, their mutual approach and separation can be controlled. The mutual approach and separation of the two sliders 204 can adjust the distance between the two centering plates 205.

The centering plate 205 is located on the top surface of the lower die 105. By controlling the cylinder 103 to lower the hammer head 104, the stamping sheet located on the top surface of the lower die 105 can be stamped accordingly.

[0025] During use, the stamping sheet to be processed is taken out and placed flat on the top surface of the lower die 105. Subsequently, the linear motor 212 is started. The linear motor 212 can drive the moving plate 208 to move. The movement of the moving plate 208 can drive the movement of the two first rotating seats 209. The movement of the two first rotating seats 209 can drive one end of the two transmission rods 210 to move. The movement of one end of the two transmission rods 210 can drive the second rotating seats 211 and the sliders 204 at the other end to move on the sliding rods 207. By controlling the synchronous movement of the two sliders 204, their approaching and separating from each other can be controlled. The approaching and separating of the two sliders 204 can adjust the distance between the two centering plates 205. Furthermore, by the approaching of the two centering plates 205, the centering of the stamping sheet to be processed can be conveniently achieved. At the same time, the distance between the two centering plates 205 can also be adjusted in advance according to the size of the stamping sheet to be processed, so that the stamping sheet to be processed is aligned between the two centering plates 205 and inserted therein to achieve the centering effect of the stamping sheet to be processed. The operator can select the appropriate centering method according to actual needs.

[0026] In summary, the automatic centering mechanism for the stamping die can control the approaching and separating of the two centering plates 205 through the linear motor 212. Furthermore, by the approaching of the two centering plates 205, the centering of the stamping sheet to be processed between the two centering plates 205 can be conveniently achieved. At the same time, the distance between the two centering plates 205 can also be adjusted in advance according to the size of the stamping sheet to be processed for adaptation, so that the stamping sheet to be processed is aligned between the two centering plates 205 and inserted therein to achieve the centering effect of the stamping sheet to be processed, effectively improving the centering efficiency of the stamping sheet to be processed and having stronger practicability.
