[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-7 This utility model provides a technical solution: a high-utilization punching die; specifically, it consists of an upper die base 1 and a lower die base 2. The essential structures on the upper die base 1 and lower die base 2, such as guide fixing seats, guide sleeves, safety level sleeves, and outer guide pillars, are all existing well-known technologies and will not be described in detail here. An adjustment mechanism is provided on the end face of the upper die base 1 near the lower die base 2. A pad 11 is provided between the upper die base 1 and the lower die base 2, located on the end face of the lower die base 2 near the upper die base 1. The end face of the pad 11 near the upper die base 1... A second toothed plate 10 is fixed to the surface, and the second toothed plate 10 is matched and correspondingly set with the adjustment mechanism. The position of the adjustment mechanism is adjusted to allow for misalignment and engagement with the second toothed plate 10. When the adjustment mechanism is misaligned with the second toothed plate 10, the product between the upper die holder 1 and the lower die holder 2 is not trimmed or punched. When the adjustment mechanism is engaged with the second toothed plate 10, the product between the upper die holder 1 and the lower die holder 2 can be trimmed and punched simultaneously. This can improve the punching efficiency between the upper die holder 1 and the lower die holder 2 and increase the utilization rate.
[0024] The adjustment mechanism includes a cylinder 6, with a first toothed plate 8 rotatably connected to the end of the cylinder 6. The first toothed plate 8 and the second toothed plate 10 are positioned and matched. A limit block 4 is provided on the side of the first toothed plate 8, and a guide block 5 is provided at the end of the first toothed plate 8. When the upper mold base 1 and the lower mold base 2 are closed, the cylinder 6 drives the first toothed plate 8 to be misaligned and engaged with the fixed second toothed plate 10. This allows the upper mold base 1 and the lower mold base 2 to perform slicing and punching, improving the utilization rate.
[0025] A sensor 9 is fixed on the upper mold base 1. When the sensor 9 approaches the lower mold base 2, a signal is output through the computer to control the cylinder 6, thereby providing power to combine the mold closing of the upper mold base 1 and the lower mold base 2 to slice and punch the product.
[0026] A pressure plate 19 is fixed to the end face of the pad 11, and a cutting punch 18 is fixed to the side end of the pressure plate 19. Combined with the upper die base 1 and the lower die base 2, the cutting punch 18 can be used to punch the corresponding product. At the same time, combined with the fixing plate 12 fixed to the end face of the lower die base 2, a die cutting edge 13 is fixed on the fixing plate 12, and a cutting edge plate 14 is fixed at the position corresponding to the cutting punch 18. Thus, the die cutting edge 13 and the cutting punch 18 can be used to cut edges and punch holes at the same time, thereby improving efficiency.
[0027] A nitrogen spring 16 is fixed at the upper edge of the lower mold base 2. The nitrogen spring 16 passes through the pad 11 and is correspondingly set with the upper mold base 1. A nitrogen spring 7 is fixed on the upper mold base 1. The nitrogen spring 7 is offset from the nitrogen spring 16, which facilitates material feeding between the upper mold base 1 and the lower mold base 2.
[0028] A floating block 15 is fixed on the upper end face of the blade plate 14. The floating block 15 can further increase the lifting height of the product, making it easier for the operator to take the product out.
[0029] A guide post 17 is fixed to the lower end edge of the pad 11. The guide post 17 is fixed to the end face of the pad 11 near the upper mold base 1. The guide post 17 can make the upper mold base 1 more stable when the upper and lower molds are closed.
