[0035] Referring to Figure 1 and Figure 2 ,a hardware stamping die for facilitating the replacement of a stamping head according to the present utility model includes a fixing plate 1. One end of a water tank 2 penetrates and is fixedly connected with heat dissipation fins 3. The top of the water tank 2 penetrates and is slidably connected with an end cover 6. A fixing ring 10 is fixedly connected to the inner wall of the upper circulation groove 9. A stamping head 11 is threadedly connected to the inner wall of the fixing ring 10. The end cover 6 can protect the coolant inside the water tank 2, and rotating the stamping head 11 can replace the stamping head 11.

[0036] Referring to Figure 1 and Figure 3 ,one side of the fixing plate 1 is fixedly connected with a water tank 2. Both sides of the bottom of the fixing plate 1 are fixedly connected with support columns 8. The bottom of the support columns 8 is fixedly connected with a bottom plate 7. A collection groove 19 is arranged on the inner wall of the bottom plate 7. Both sides of the middle of the top of the fixing plate 1 penetrate and are rotatably connected with upper brackets 15. Both sides of the collection groove 19 are rotatably connected with lower brackets 16. A connecting rod 17 penetrates and is rotatably connected between the lower bracket 16 and the upper bracket 15. One side of the lower bracket 16 penetrates and is rotatably connected with a threaded rod 18, and the threaded rod 18 penetrates and is threadedly connected with one side of the collection groove 19. A pull rod 14 is arranged on the outer ring of the connecting rod 17. A die spring 4 is fixedly connected to the top of the fixing plate 1. The top of the die spring 4 is fixedly connected with a top plate 5. The bottom of the top plate 5 is fixedly connected with an upper circulation groove 9. A cooling device is arranged inside the water tank 2. The collection groove 19 collects the pressed and dropped waste materials, and there are baffles beside the collection groove 19 to prevent the waste materials from sliding off from both sides of the collection groove 19 when the collection groove 19 moves.

[0037] Referring to Figure 1 and Figure 4 and Figure 5 ,the cooling device includes a water pump 20. The water pump 20 is fixedly connected to the bottom of the inner wall of the water tank 2. The output end of the water pump 20 is fixedly connected with a delivery water pipe 21, and the delivery water pipe 21 penetrates and is fixedly connected with the top of the water tank 2. The upper delivery water pipe 21 penetrates and is fixedly connected with one side of the outer ring of the upper circulation groove 9. The other side of the outer ring of the upper circulation groove 9 penetrates and is fixedly connected with an input water pipe 22. The top of the lower input water pipe 22 penetrates and is fixedly connected with a lower circulation groove 13, and the lower circulation groove 13 is arranged inside the lower die 12. The upper circulation groove 9 is beside the stamping head 11 and can dissipate heat from the stamping head 11. The lower circulation groove 13 is arranged inside the lower die 12 and can dissipate heat from the lower die 12 and the pressed and formed material.

[0038] Working principle: The stamping head 11 presses the lower die 12. The scrap materials pressed off will fall into the collection groove 19 inside the bottom plate 7. By pulling the pull rod 14, the pull rod 14 enables the upper bracket 15 and the lower bracket 16 to rotate through the connecting rod 17. The upper bracket 15 and the lower bracket 16 move forward and approach each other, driving the collection groove 19 at the bottom to rise and move forward, discharging the scrap materials inside the collection groove 19. There is no need to grab the scrap materials in the groove, preventing the harm of the scrap materials to the human body. The coolant is sent from the conveying water pipe 21 into the upper circulation tank 9 and the lower circulation tank 13 through the water pump 20. The coolant inside the upper circulation tank 9 and the lower circulation tank 13 is pumped into the water tank 2 through the input water pipe 22. The heat dissipation fins 3 dissipate the heat of the coolant sent by the input water pipe 22, ensuring that the coolant is always in a low-temperature state, and can efficiently cool the stamping head 11, the lower die 12 and the pressed and formed materials.
