Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, specifically a stamping die for metal processing. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies, or simply cold stamping dies. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts.

[0003] Metal processing refers to the use of various processing techniques to process metal into products of certain shapes, sizes, and specifications. In the metal processing process, stamping dies are used. By placing the metal in the stamping die and applying pressure to the metal using a die mounted on a press, the metal is separated or plastically deformed, thereby obtaining the desired parts. However, during the pressing process of the stamping die, when the metal separates, debris will fly out at the moment of separation. These debris can easily fly out of the die through the gap when the stamping die closes, which means that if a worker is nearby, the flying debris can easily scratch the worker's skin, thus posing a safety hazard.

[0004] In summary, this utility model provides a stamping die for metal processing to solve the above-mentioned problems. Utility Model Content

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1-4 As shown, this utility model provides a stamping die for metal processing, including a base 1, a stamping die 2 is provided at the top of the base 1, and a fixing component for the stamping die 2 is provided inside the base 1. The stamping die 2 includes a lower die 201 and an upper die 202. The upper die 202 is located at the top of the lower die 201. A guide sleeve 203 is connected to the bottom of the upper die 202. A stamping head 204 is installed at the bottom of the upper die 202. A guide post 205 is installed at the top of the lower die 201. A stamping plate 206 is installed at the top of the lower die 201. A protective component is installed on the outer wall of the upper die 202.

[0023] Please refer to Figure 1-4 The fixing assembly includes a bidirectional threaded rod 3, a bearing 4, a threaded sleeve 5, a clamping block 6, and a fixing pin 7. The bidirectional threaded rod 3 is installed horizontally inside the base 1. The bearing 4 is connected to one end of the bidirectional threaded rod 3 and located inside the base 1. The threaded sleeve 5 is threadedly connected to the surface of the bidirectional threaded rod 3. The clamping block 6 is located at the top of the base 1. The fixing pin 7 passes through the rotating handle of the bidirectional threaded rod 3 and is connected to one side of the base 1. By using the fixing assembly, the stamping die 2 can be replaced according to the different metal processing, thus facilitating replacement.

[0024] Please refer to Figure 1-4 The opposing threads on the surface of the bidirectional threaded rod 3 correspond to each other. The bidirectional threaded rod 3 is rotatably connected to the base 1 through the bearing 4. The bidirectional threaded rod 3 and the bearing 4 are rotatably connected to the base 1, so that the bidirectional threaded rod 3 can rotate stably inside the base 1 through the bearing 4, reducing the deviation caused by the rotation of the bidirectional threaded rod 3.

[0025] Please refer to Figure 1-4The bottom end of the clamping block 6 is connected to the top end of the threaded sleeve 5. The clamping block 6 forms a threaded transmission connection with the bidirectional threaded rod 3 through the threaded sleeve 5. The bidirectional threaded rod 3 rotates to drive the threaded sleeve 5 to move, and at the same time the threaded sleeve 5 drives the clamping block 6 to move together to clamp and fix the stamping die 2.

[0026] Please refer to Figure 1-4 The bidirectional threaded rod 3 is fixedly connected to the base 1 through the fixing pin 7. The bidirectional threaded rod 3 and the fixing pin 7 are fixedly connected to the base 1. After the bidirectional threaded rod 3 is working, the fixing pin 7 can be removed and connected to the base 1, thereby preventing the bidirectional threaded rod 3 from rotating and improving the stability of the bidirectional threaded rod 3 in use.

[0027] Please refer to Figure 1-4 The protective components include a protective cover 8, a fixing block 9, a spring 10, and a limiting block 11. The protective cover 8 is located outside the upper die 202. The fixing block 9 is installed on the outer wall of the upper die 202. The spring 10 is installed inside the fixing block 9, and one end of the spring 10 is connected to the inner wall of the fixing block 9. The limiting block 11 is connected to the other end of the spring 10. By using the protective components, the metal processing of the stamping die 2 is reduced, and the debris generated during the stamping separation is reduced, thereby playing a protective role.

[0028] Please refer to Figure 1-4 The protective cover 8 is made of PVC. A protrusion is connected to the bottom of the protective cover 8. The protrusion at the bottom of the protective cover 8 is elastically connected to the fixing block 9 through the limiting block 11 and the spring 10. The protrusion, the limiting block 11, the spring 10 and the fixing block 9 form an elastic connection. The protrusion is squeezed by the spring 10 driven by the limiting block 11, so that the protective cover 8 can be fixed to the top of the fixing block 9. This makes it easier to reduce the flying of debris generated when the metal is separated by stamping.

[0029] Specific working principle: such as Figure 1-4As shown, when using this metal processing stamping die, first take out the corresponding metal processing stamping die 2, then place the stamping die 2 at the bottom of the base 1. Next, rotate the bidirectional threaded rod 3 so that the bidirectional threaded rod 3 rotates along the inner ring of the bearing 4 inside the base 1. Then, the threaded sleeve 5 moves along the thread on the surface of the bidirectional threaded rod 3. Then, the clamping block 6 moves together with the movement of the threaded sleeve 5, and then the clamping block 6 is fixed close to both sides of the lower die 201 of the stamping die 2, so that the stamping die 2 is stably installed at the top of the base 1. Then, take out the fixing pin 7 and screw it into the opening of the rotating handle of the bidirectional threaded rod 3, so that the fixing pin 7 is screwed into the side wall of the base 1 to fix the bidirectional threaded rod 3, so as to prevent the rotation of the bidirectional threaded rod 3 from affecting the fixation of the stamping die 2. At the same time, when different metals need to be processed, the above steps facilitate the disassembly and replacement of the stamping die 2, thus playing a convenient replacement role. Next, take out the protective cover 8 near the opening at the top of the fixing block 9, and then insert the protrusion at the bottom of the protective cover 8 into the fixing block. In the opening at the top of the 9th layer, the protrusion at the bottom of the protective cover 8 presses against the limiting block 11, causing the limiting block 11 to cause the spring 10 to contract and deform. After the protective cover 8 is installed, the limiting block 11 quickly rebounds due to the elasticity of the spring 10 and then locks into the opening on the side wall of the protrusion at the bottom of the protective cover 8. Immediately afterwards, the stamping die 2 is fixed on the worktable of the press by the base 1. Then the metal is placed on the stamping plate 206 at the top of the lower die 201. Then the press is started to press down, causing the upper die 202 to descend, while the guide sleeve 203 moves along the... The guide post 205 moves along the surface, and the stamping head 204 at the bottom of the lower die 201 cooperates with the stamping plate 206 at the top of the lower die 201 to stamp the metal. When the stamping die 2 processes the metal, the protective cover 8 is shielded between the upper die 202 and the lower die 201. The protective cover 8 reduces the amount of debris that splashes out when the metal is separated by stamping, thus playing a protective role. At the same time, the height of the protective cover 8 will not collide with the base 1. This is the characteristic of the stamping die for metal processing.
