[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. During manufacturing, hinges are often produced by punching holes in the surface of the workpiece using a punching machine, followed by subsequent machining.
[0003] In existing technology, both the upper and lower die holders of the hinge punching equipment will wear during use. Therefore, after a period of use, the upper and lower die holders need to be disassembled and replaced. Currently, the lower die holder is mostly fixed to the punching equipment with bolts. During installation, the threaded hole needs to be aligned with the mounting hole, which increases the installation time of the lower die holder and makes the installation slow. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that in the existing hinge punching equipment, both the upper and lower die bases will wear during use. Therefore, after a period of use, the upper and lower die bases need to be disassembled and replaced. Currently, the installation between the lower die base and the punching equipment is mostly fixed with bolts. During installation, the threaded hole needs to be aligned with the mounting hole, which increases the installation time of the lower die base and makes the installation slow. Therefore, a punching equipment for hinge processing is proposed.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] Example 1: As Figures 1-3 As shown, this utility model provides a punching device for hinge processing, including a loading seat 1. A limiting groove 21 is provided in the middle of the upper end of the loading seat 1. A through groove 22 is provided in the middle of the limiting groove 21. A limiting base 7 is engaged inside the limiting groove 21. A lower die base 6 is fixedly connected to the upper end of the limiting base 7. A limiting inclined groove 16 is provided in the middle of both sides of the upper end of the limiting base 7. An electric telescopic rod 9 is provided in the middle of both sides of the upper end of the loading seat 1. An assembly side plate 18 is fixedly connected to the output end of the electric telescopic rod 9. A limiting pressure block 11 is fixedly connected to one side of the assembly side plate 18. One side of the lower end of the limiting pressure block 11 is inclined. A limiting protrusion 8 is fixedly connected to the upper end of the loading seat 1 and at the edge of the limiting groove 21.
[0022] The specific settings and functions of this embodiment are described in detail below. By setting the limiting pressure block 11 and the limiting inclined groove 16, the limiting base 7 is compressed and limited by the inclined extrusion method. The limiting base 7 is limited by the limiting slot 21. In this way, the lower mold base 6 can be quickly disassembled and assembled, making the replacement of the lower mold base 6 more convenient and quick. By setting the limiting protrusion 8, the movement direction of the limiting base 7 can be limited when the lower mold base 6 is installed, which can facilitate the guiding installation of the limiting base 7. At the same time, it increases the contact area with the limiting base 7 after it is installed in the limiting slot 21, ensuring the stability of the limiting base 7 during operation.
[0023] Example 2: Figures 1-3As shown, the lower end of the loading seat 1 and both sides of the through groove 22 are fixedly connected with second reinforcing ribs 23. Restricting seats 14 are fixedly connected to both sides of the middle section between the two second reinforcing ribs 23. A collection box 13 is slidably connected between the two restricting seats 14. Magnets 19 are fixedly connected to both sides of the upper end of the collection box 13. A filter frame 20 is installed inside the collection box 13. A first reinforcing rib 15 is fixedly connected between one side of the mounting side plate 18 and the upper end of the restricting pressure block 11. An end plate 17 is provided above the loading seat 1. Guide rods 2 are fixedly connected between the four corners of the loading seat 1 and the end plate 17. An upper mold base mounting plate 3 is provided between the loading seat 1 and the end plate 17. Sliding seats 5 are fixedly connected to the four corners of the upper and lower ends of the upper mold base mounting plate 3. The sliding seats 5 are slidably connected to the guide rod 2. Assembly seats 10 are fixedly connected to both sides of the middle part of the upper end of the loading seat 1. The assembly seats 10 are fixedly connected to the electric telescopic rod 9. A support base 12 is fixedly connected to the lower end of the loading seat 1. A hydraulic cylinder 4 is fixedly connected to the upper end of the end plate 17. The output end of the hydraulic cylinder 4 passes through the end plate 17 and is fixedly connected to the upper mold base mounting plate 3. The lower end of the collection box 13 is fixedly connected to a connection port for connecting to the air extraction equipment, which can promote the entry of waste materials.
[0024] The overall effect of this embodiment is that the collection box 13 and the limiting seat 14 are installed in a sliding manner to facilitate the cleaning of the collection box 13. The magnet 19 is used to limit the collection box 13 by magnetic attraction, which can ensure the stability of the collection box 13 during use. The filter frame 20 is used to prevent waste from flowing out of the connection port and damaging the air extraction equipment.
[0025] The usage and working principle of this device are as follows: During punching, the hinge blank is placed in the lower die base 6, and the hydraulic cylinder 4 is extended to push the upper die base mounting plate 3 to move, so that the upper die base mounted on the upper die base mounting plate 3 punches the blank and punches holes in the hinge blank. The waste material after punching falls into the collection box 13. As needed, an air extraction device can be selectively installed at the connection port. When the air extraction device is connected, the waste material falls into the collection box 13 through the flow of air. When the lower die base 6 needs to be replaced, simply control the two electric telescopic rods 9 to retract, so that the limiting pressure block 11 is disconnected from the limiting inclined groove 16. Then, the lower die base 6 can be taken out. The new lower die base 6 is placed in the limiting protrusion 8, so that the side of the limiting base 7 contacts the inner wall of the limiting protrusion 8. Push the lower die base 6 until the limiting base 7 is inserted into the limiting slot 21. Then, control the electric telescopic rods 9 to extend, so that the limiting pressure block 11 is connected to the limiting inclined groove 16, and the limiting base 7 is squeezed.
[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
