Description

Technical Field

[0001] The utility model relates to the technical field of metal part stamping dies, and particularly relates to a metal part stamping die. Background Art

[0002] In modern manufacturing, the demand for metal parts is increasing day by day, and their application scope is extensive, covering many fields such as automobiles, electronics, aerospace, machinery, etc. In order to meet the requirements of high-precision, high-efficiency and high-quality production of metal parts, a metal part stamping die has emerged. After retrieval, the publication (announcement) number: CN220717383U, discloses a metal part stamping die. In this device, a collection part is provided. By sliding the lower support plate on the fixed bottom frame, it is convenient to demold the stamped metal parts, and then it is convenient for them to fall on the raw material plate. And by inserting the raw material plate into the restraint frame, it is assisted to adjust the raw material plate, and then it is convenient for its use. And by fixing the collection frame on the restraint frame, it is kept stable under the action of the support frame, and it is convenient to slide the metal parts down through the inclined plane, avoiding collecting them by the way of dropping, and thus avoiding damage during the dropping process, making it convenient for use. However, there are deficiencies: after the metal parts are demolded, they will fall on the raw material plate. After the upper stamping die and the lower stamping die are fully unfolded, it is still necessary to push the stamped metal parts to make them slide into the collection frame, which delays the stamping of the next metal part, affects the continuity of processing, and thus also affects the production efficiency. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a metal part stamping die is proposed.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By providing the support rod, the frame body, the upper mold, the lower mold, the top block, the first spring, the second spring, the hydraulic cylinder, the flange, the guide rod, the short rod, the second spring, the long rod, the short board and the long board, after placing the raw material plate to be stamped on the lower mold, the hydraulic cylinder drives the flange, so that the upper mold connected to the flange presses downward. During the stamping process, the upper mold will press the short board to rotate on the long rod.

This method of using the long board to push the stamped metal part after the upper mold is lifted can push the metal part onto the slideway before the upper mold is fully lifted, and the next stamping can be carried out immediately after the upper mold is lifted, improving the stamping efficiency and further improving the production efficiency;

[0014] 2. By providing the support rod, the frame body, the water tank, the pump body, the pipe body and the nozzles, the pump body sucks the cooling water in the water tank into the pipe body, and then sprays the coolant in a spray manner onto the left and right edge areas of the lower mold for cooling. This can reduce the heat generated by friction during stamping and prevent the lower mold from deforming due to excessive temperature. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1, refer to Figures 1 to 5, A stamping die for metal parts, including support columns 1. A frame 2 is fixedly connected to multiple groups of support columns 1. The frame 2 supports the upper die 21 and the lower die 3 for stamping work. The lower die 3 is installed on the frame 2. The lower die 3 is slidably connected to a top block 4. The top block 4 is fixedly connected to a first spring 5. The top block 4 can lift the stamped metal part through the first spring 5 to complete the demolding function. The first spring 5 is fixedly connected to the frame 2. Two short rods 6 are fixedly connected to the frame 2. The two short rods 6 are rotatably connected to the same long rod 8 through a connecting shaft. Second springs 7 are fixedly connected to both ends of the two short rods 6 and the long rod 8. The second spring 7 is a torsion spring. A short board 9 and a long board 10 are fixedly connected to the long rod 8. The overall process is that after placing the raw material plate on the lower die 3, the hydraulic cylinder 19 drives the flange 20, so that the upper die 21 connected to the flange 20 presses downward. During the process, the upper die 21 will press the short board 9, thereby driving the long rod 8 to rotate on the two short rods 6. The edge of the upper die 21 will push aside the short board 9 and make the short board 9 fit against the upper end of the upper die 21. When the stamping is completed and the upper die 21 rises, the top block 4 will demold the metal part through the resilience of the first spring 5. The upper die 21 will press against the edge of the short board 9, allowing the long board 10 to rotate to push the just-demolded metal part, so that it is pushed onto the slideway 11 and slides into the collection box 12 to complete the collection. By lifting the upper die 21 and using the long board 10 to push the stamped metal part, the metal part can be pushed onto the slideway 11 before the upper die 21 is completely lifted. After the upper die 21 is lifted, the next stamping can be carried out immediately, thereby improving the production efficiency.

[0023] In this embodiment, a water tank 13 is installed on the frame 2. A pump body 14 is installed on the frame 2. The model of the pump body 14 is selected according to the actual working requirements. The water tank 13 is connected to the pump body 14. The pump body 14 is connected to a pipe body 15. Multiple spray nozzles 16 are installed on the pipe body 15. The spray nozzles 16 can spray cooling water in the form of mist on both sides of the lower die 3. The frame 2 is fixedly connected to the pipe body 15. A slideway 11 is fixedly connected to the frame 2. Guardrails are provided on both sides of the slideway 11 to prevent the metal parts from falling outside. One end of the slideway 11 is in contact with the lower die 3. A collection box 12 is placed at the other end of the slideway 11. The collection box 12 can collect all the metal parts. The collection box 12 is placed in contact with the frame 2. An inlet 17 is fixedly connected to the water tank 13. A drain 18 is fixedly connected to the water tank 13. Multiple spray nozzles 16 are evenly distributed on both sides of the pipe body 15. A hydraulic cylinder 19 is installed on the frame 2. A flange 20 is installed on the hydraulic cylinder 19. An upper die 21 is installed at one end of the flange 20. Multiple guide rods 22 are fixedly connected to the upper die 21. The multiple guide rods 22 are slidably connected to the frame 2.

[0024] Working principle of this embodiment: During use, place the raw material plate on the lower die 3, and then use the hydraulic cylinder 19 to push the flange 20 to make the upper die 21 press downwards. During the downward movement, the upper die 21 will push the short plate 9 and drive the long rod 8 to rotate on the two groups of short rods 6. Then, the short plate 9 will fit on the upper end of the upper die 21. After the stamping is completed, use the hydraulic cylinder 19 to raise the upper die 21. The ejector block 4 will first demold the metal part using the resilience of the first spring 5. Then, the upper die 21 will push the short plate 9 and the long plate 10 to rotate on the long rod 8, so that the long plate 10 can dial the just-demolded metal part onto the slideway 11 and finally enter the collection box 12 to complete the collection. Then, suck the coolant in the water tank 13 into the pipe body 15 through the pump body 14, and spray the mist from the nozzle 16 on the left and right edges of the lower die 3, which can effectively take away the heat generated by the friction of the lower die 3 and prevent the deformation of the lower die 3.
