Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die capable of quickly replacing stamping shapes. Background Art

[0002] At present, a stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method in which, at room temperature, a die installed on a press applies pressure to a material to cause separation or plastic deformation, so as to obtain the required parts. Since most parts production will use stamping dies, it is necessary to optimize the processing of stamping dies.

[0003] For example, in the Chinese utility model patent with the publication number CN212190981U, a stamping die for metal sheet processing is disclosed. In the above-mentioned prior art, although a blanking port is opened on the workbench of the stamping machine, so that the finished products and waste materials can slide down to the lower part of the workbench through the blanking port of the workbench, when processing different products, it is necessary to disassemble and replace the stamping die, and the process of disassembling and replacing the stamping die is not only cumbersome but also wastes a lot of time and affects the processing efficiency. Therefore, it is necessary to design a stamping die that can change the stamping shape without disassembling the stamping die. Summary of the Utility Model

[0004] To solve the technical problem that it is relatively cumbersome to change the stamping shape by disassembling and replacing the stamping die, the utility model provides a stamping die capable of quickly replacing stamping shapes.

[0005] The utility model is realized by the following technical solutions: A stamping die capable of quickly replacing stamping shapes includes a lower die plate, an upper die plate is arranged on one side of the lower die plate, deformation components capable of quickly replacing stamping shapes are arranged on one side of both the lower die plate and the upper die plate, and a plurality of fixing components for fixing the deformation components are arranged on each deformation component. The deformation component includes a fixed frame fixedly installed on one side of the lower die plate, a die block arranged inside the fixed frame, and fixing strips arranged on both sides of the die block.

[0006] Through the above technical solutions, when the stamping shape needs to be replaced, the fixing effect of the deformation component is cancelled by using the fixing component, and then the deformation component is replaced to complete the replacement of the stamping shape.

[0007] As a further improvement of the above solution, fixing grooves adapted to the adjacent fixing strips are opened on both sides of each die block, both ends of the fixing strip penetrate through the adjacent fixed frame and extend to the outside thereof, and fixing ports are opened at both ends of each fixing strip.

[0008] Through the above technical solution, the fixing bar will cooperate with the fixing groove to replace and fix the die block.

[0009] As a further improvement of the above solution, the fixing component includes a fixing block fixedly installed on one side of the fixing frame, a pushing spring fixedly installed on one side of the fixing block, and a clamping block fixedly installed at one end of the pushing spring. Each clamping block is adapted to the fixing port of the adjacent fixing bar.

[0010] Through the above technical solution, the clamping block will be stuck into the fixing port of the fixing bar, so that the fixing bar will be fixed and unable to move.

[0011] As a further improvement of the above solution, limiting bars with sliding grooves are provided on both sides of each clamping block. Each limiting bar is fixedly installed with the fixing frame, and each clamping block is slidably matched with the adjacent limiting bar through the sliding groove.

[0012] Through the above technical solution, the limiting bar will limit the movement of the clamping block to prevent the clamping block from moving and deviating and being unable to fix and limit the fixing bar.

[0013] As a further improvement of the above solution, insertion slots are provided on both sides of the inner wall of the fixing frame. An extrusion block is provided inside each insertion slot. A rotating groove is provided on one side of each extrusion block, and a roller is rotatably installed inside each rotating groove.

[0014] Through the above technical solution, the roller will closely adhere to the die block to prevent the die block from shaking left and right.

[0015] As a further improvement of the above solution, a limiting plate is provided on one side of each extrusion block. A limiting plate fixedly installed with the fixing frame is slidably sleeved on each limiting plate, and the limiting plate is arranged in a "C" shape.

[0016] Through the above technical solution, the limiting plate will prevent the extrusion block from shaking and causing the die block to be unstable.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a deformation component and a fixing component in the present utility model, when it is necessary to replace the stamping shape, the fixing component is moved, so that the fixing effect of the deformation component is released. Then, the die block in the deformation component is replaced, and finally, the deformation component is fixed again by using the fixing component to complete the replacement of the stamping shape. Such a setting can not only replace the stamping shape but also accelerate the replacement speed of the stamping shape and improve the processing efficiency of parts. Description of the Drawings

[0024] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0025] Please refer to Figures 1 - 3 , A stamping die capable of quickly replacing the stamping shape in this embodiment includes a lower die plate 1. One side of the lower die plate 1 is provided with an upper die plate 2. Deformation components capable of quickly replacing the stamping shape are provided on one side of both the lower die plate 1 and the upper die plate 2. A plurality of fixing components for fixing the deformation components are provided on each deformation component. The deformation component includes a fixing frame 301 fixedly installed on one side of the lower die plate 1, a die block 302 arranged inside the fixing frame 301, and fixing strips 303 arranged on both sides of the die block 302. Fixing grooves adapted to the adjacent fixing strips 303 are opened on both sides of each die block 302. Both ends of the fixing strip 303 penetrate through the adjacent fixing frame 301 and extend to the outside thereof. Fixing openings are opened at both ends of each fixing strip 303. When replacing the stamping shape, use the fixing component to cancel the fixing effect of the deformation component, and then replace the deformation component to complete the replacement of the stamping shape.

[0026] Refer to Figures 1 - 3, the fixing component includes a fixing block 401 fixedly installed on one side of the fixing frame 301, a pushing spring 402 fixedly installed on one side of the fixing block 401, and a clamping block 403 fixedly installed at one end of the pushing spring 402. Each clamping block 403 is adapted to the fixing port of the adjacent fixing strip 303. Limiting strips 5 with sliding grooves are provided on both sides of each clamping block 403. Each limiting strip 5 is fixedly installed with the fixing frame 301. Each clamping block 403 is slidably matched with the adjacent limiting strip 5 through the sliding groove. The clamping block 403 will snap into the fixing port inside the fixing strip 303, so that the fixing strip 303 will be fixed and unable to move. The limiting strip 5 will limit the movement of the clamping block 403 to prevent the clamping block 403 from moving and offsetting and being unable to fix and limit the fixing strip 303.

[0027] Combined Figures 1 - 3 , insertion slots are provided on both sides of the inner wall of the fixing frame 301. An extrusion block 6 is provided inside each insertion slot. A rotating groove is provided on one side of each extrusion block 6. A roller 7 is rotatably installed inside each rotating groove. A limiting plate 8 is provided on one side of each extrusion block 6. A limiting plate 9 fixedly installed with the fixing frame 301 is slidably sleeved on each limiting plate 8. The limiting plate 9 is arranged in a "C" shape. The roller 7 will closely adhere to the die block 302 to prevent the die block 302 from shaking left and right.

[0028] The implementation principle of a stamping die capable of quickly replacing the stamping shape in the embodiment of the present application is as follows: When it is necessary to replace the stamping shape, slide the clamping block 403 to release the fixing effect of the fixing strip 303. Then, the fixing strip 303 can be slid left and right, and the fixing strip 303 can be pulled out from the inside of the fixing frame 301. In this way, the limiting effect of the die block 302 will be released. Then, take down the die block 302 and replace it with the required die block 302. The replaced die block 302 will be located in the middle position under the extrusion of the two rollers 7 to prevent the die block 302 from shifting left and right. Then, insert the fixing strip 303 into the fixing frame 301 to cooperate with the fixing groove of the die block 302 to limit the die block 302. In this way, together with the two rollers 7, the position of the die block 302 can be completely fixed. Finally, insert the clamping block 403 back into the fixing port inside the fixing strip 303 to complete the fixing of the fixing strip 303. Finally, the die block 302 will be completely fixed and can be used for stamping operations. Moreover, the roller 7 can also be replaced according to the size of the die block 302. Only need to slide the limiting plate 8, and then take out the extrusion block 6 and replace it with a suitable extrusion block 6 to realize the replacement of the roller 7. Such a setting can quickly replace the stamping shape and improve the processing efficiency.

[0029] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention belong to the scope required to be protected by the present invention.
