[0002] Stamping parts rely on presses and dies to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation. The forming of metal sheets is usually achieved by stamping.

[0003] For example, the Chinese utility model patent with patent publication number CN220462005U includes a lower mold, an upper mold, a lower mold base, an upper mold base, a stamping block, and a stamping cylinder. This patent can use an air pump to fill the inside of the support base with gas pressure, so that thrust is generated at the air hole, so that the stamping part adhered to the top of the support base can be demolded from the lower mold base, and the telescopic end of the lifting cylinder can drive the push block to be ejected from the through groove, and the tightly connected stamping part can be ejected from the lower mold base. However, when the push plate is pushed by the electric push rod to align the stamping part, it can only be done in two directions, left and right, and it is impossible to ensure that the stamping part is located in the center, which makes the stamping precision have certain deficiencies. In view of this, we propose a stamping die for stamping parts. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) For this stamping part stamping die, when aligning and positioning the stamping part, the electric push rod drives the displacement plate to move synchronously. When the displacement plate moves, the two driving plates are driven to approach each other through the linkage assembly arranged thereon. When the driving plate moves, the alignment plate is pushed by the spring to move. When the alignment plate moves, it aligns and positions the stamping part.

At the same time, when the threaded rod rotates, it will move vertically synchronously. When the threaded rod moves, it will drive the locking plate to move. After the locking plate moves, it contacts the first limiting rod and is fixed by the friction between the two, so that the connection between the driving plate and the alignment plate is temporarily fixed, and there is no need to push by the spring. Through the above structure, it can be realized that the connection between the driving plate and the alignment plate can be adjusted by the threaded rod, and then the final movement distance when the driving plate is driven to move can be adjusted, increasing the application range of the overall device.

The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0023] Please refer to Figures 1-4The utility model provides a technical solution: a stamping die for stamping parts, including a bottom plate 1, a support rod 2 is fixedly connected to the upper surface of the bottom plate 1, a top plate 3 is fixedly connected to the upper end of the support rod 2, a stamping assembly 4 is arranged on the lower surface of the top plate 3, a lower die 5 is fixedly connected to the upper surface of the bottom plate 1, through grooves are respectively provided on the front and rear side surfaces of the lower die 5, a swiping plate 6 is slidably connected to the inner wall of the through groove, a first limiting rod 7 is respectively fixedly connected to the opposite side surfaces of the two swiping plates 6, a driving plate 8 is slidably sleeved on the outer surface of the first limiting rod 7, a spring 9 is fixedly connected to the side surface of the swiping plate 6 close to the driving plate 8, two mounting plates 10 are fixedly connected to the upper surface of the lower die 5, and an electric push rod 11 is fixedly connected to the side surface of the two mounting plates 10 close to each other. One end of the two electric push rods 11 that is close to each other is fixedly connected with a displacement plate 12, and a linkage component is arranged on the displacement plate 12. The stamping component 4 described in the article is an existing structure. For details, please refer to patent publication number CN220462005U. When the stamping part is centered and positioned, the displacement plate 12 is synchronously driven to move by the electric push rod 11. When the displacement plate 12 moves, the linkage component arranged thereon drives the two driving plates 8 to approach each other. When the driving plate 8 moves, the spring 9 is used to push the aligning plate 6 to move. The aligning plate 6 aligns and positions the stamping part during movement. Through the above structure, when the stamping part is centered and positioned, the front and rear aligning positioning can be automatically completed as the electric push rod 11 pushes, without adding additional drive, thereby improving energy utilization.

[0024] Furthermore, the linkage component includes two inclined plates 13. The two inclined plates 13 are fixedly connected to the surface of the displacement plate 12 close to the lower die 5. The adjacent surfaces of the two inclined plates 13 are arranged in an inclined shape. Oblique grooves 14 are respectively formed on the left and right side surfaces of the driving plate 8. The oblique grooves 14 are adapted to the inclined plates 13. Two second limiting rods 15 are respectively fixedly connected to the front and rear side surfaces of the lower die 5. The driving plate 8 is slidably sleeved on the outer surface of the second limiting rods 15. A second spring 16 is fixedly connected to the surface of the driving plate 8 close to the lower die 5. Connecting rods 17 are respectively fixedly connected to the adjacent surfaces of the two displacement plates 12. The adjacent ends of the two connecting rods 17 slidably penetrate into the interior of the lower die 5. A second alignment plate 18 is fixedly connected to the adjacent ends of the two connecting rods 17. A cavity 19 is formed inside the driving plate 8. A locking plate 20 is slidably connected to the inner wall of the cavity 19. An arc-shaped groove adapted to the arc-shaped outer surface of the first limiting rod 7 is formed on the lower side surface of the locking plate 20. A threaded rod 21 is rotatably connected to the upper side surface of the locking plate 20. The upper end of the threaded rod 21 rotatably penetrates out of the upper side surface of the driving plate 8. When the displacement plate 12 moves, it will drive the second alignment plate 18 to move by means of the connecting rod 17. At the same time, the displacement plate 12 will also drive the inclined plate 13 to move horizontally. When the inclined plate 13 moves, it cooperates with the oblique groove 14 to squeeze the driving plate 8, thereby driving the driving plate 8 to displace. When the driving plate 8 moves, its movement track is restricted by the second limiting rod 15, and the second spring 16 for resetting the driving plate 8 is compressed. At the same time, when the threaded rod 21 rotates, it will synchronously move in the vertical direction. When the threaded rod 21 moves, it will drive the locking plate 20 to move. After the locking plate 20 moves, it contacts the first limiting rod 7 and is fixed by the friction between the two, so that the driving plate 8 and the alignment plate 6 are temporarily fixedly connected, without the need to be pushed by the spring 9. Through the above structure, the connection between the driving plate 8 and the alignment plate 6 can be adjusted by using the threaded rod 21, and then the final movement distance when the driving plate 8 is driven to move can be adjusted, increasing the applicable range of the overall device.

[0025] Working principle: When aligning and positioning the stamping parts, the electric push rod 11 drives the displacement plate 12 to move synchronously. When the displacement plate 12 moves, the linkage assembly arranged on it drives the two driving plates 8 to approach each other. When the driving plates 8 move, the alignment plate 6 is pushed to move by the spring 9. When the alignment plate 6 moves, it aligns and positions the stamping parts. When the displacement plate 12 moves, it drives the second alignment plate 18 to move by means of the connecting rod 17. At the same time, the displacement plate 12 also drives the inclined plate 13 to move horizontally. When the inclined plate 13 moves, it cooperates with the inclined groove 14 to squeeze the driving plate 8, thereby driving the driving plate 8 to displace. When the driving plate 8 moves, its movement trajectory is restricted by the second limiting rod 15, and the second spring 16 for resetting the driving plate 8 is compressed. At the same time, when the threaded rod 21 rotates, it will move vertically synchronously. When the threaded rod 21 moves, it drives the locking plate 20 to move. After the locking plate 20 moves, it contacts the first limiting rod 7 and is fixed by the friction between the two, so that the driving plate 8 and the alignment plate 6 are temporarily fixedly connected, without the need to be pushed by the spring 9.

Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
