[0018] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0019] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0020] The following will be combined with specific embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] See Figures 1 to 5 As shown, the structure of the utility model is as follows: a hardware punching die, comprising an upper die base 1, a lower die base 2 and a guide column 3 connected between the upper die base 1 and the lower die base 2, a profile male 4 is fixedly provided on the lower die base 2, and a accommodating hole 5 is opened on the profile male 4; a clamping plate 6, a pad 7 and a fixed plate 8 are sequentially provided at the bottom of the upper die base 1; a receiving cavity 10 is provided on the clamping plate 6, a top plate 11 is movably provided in the accommodating cavity 10, and a first spring 12 is provided on the top of the top plate 11; a blanking plate 9 is provided at the bottom of the fixed plate 8, a profile cavity 13 corresponding to the profile male 4 is provided on the blanking plate 9, a stripping plate 14 is movably provided in the profile cavity 13, and a pull rod 15 is provided on the stripping plate 14, which passes through the fixed plate 8, the pad 7 and the top plate 11 in sequence The plate 11 is connected; a punch 16 is installed on the fixed plate 8, and the punch 16 passes through the stripper plate 14 and corresponds to the accommodating hole 5. Specifically, the plate is placed on the profiling pin 4, and then the upper die seat 1 moves down. The stripper plate 14 contacts the plate first under the action of the spring. As the upper die seat 1 moves down, the first spring 12 is compressed, pressing the plate tightly against the profiling pin 4. Then, the profiling cavity 13 on the blanking plate 9 cooperates with the profiling pin 4 to punch out the required shape and size of the plate. At the same time, the punch 16 cooperates with the accommodating hole 5 to punch out the required hole on the plate. Then the upper die seat 1 moves up, and under the action of the first spring 12, the stripper plate 14 is pushed to push the punched hardware out of the profiling cavity 13, so as to facilitate the removal of the punched hardware.

[0022] like Figure 3 、 Figure 5 As shown, a supporting plate 17 is movably provided on the outer side of the profiler 4, and a second spring 18 is provided at the bottom of the supporting plate 17. Specifically, the supporting plate 17 is used to support the sheet before punching. During punching, the second spring 18 is compressed as the punching plate 9 moves downward, thereby avoiding interference with the cutting of the sheet by the punching plate 9 during punching.

[0023] like Figure 3 、 Figure 5 As shown, a positioning pin 19 is movably provided on the supporting plate 17, and a third spring 20 is provided at the bottom of the positioning pin 19. Specifically, the positioning pin 19 is used to position the plate. Before punching, the positioning pin 19 is extended under the action of the third spring 20 to position the plate. During punching, the punching plate 9 presses down the positioning pin 19 to shrink the third spring 20, thereby avoiding interference between the positioning pin 19 and the punching plate 9 during punching.

[0024] like Figure 3 、 Figure 5 As shown, a material guide plate 21 is provided on the supporting plate 17, and a stopper 22 is provided on one side of the material guide plate 21. Specifically, the material guide plate 21 is used to facilitate guiding the plate into the mold, and the stopper is used to position the plate.

[0025] like Figure 2 、 Figure 3 、 Figure 5 As shown, the accommodating hole 5 is communicated with the lower die base 2, and a waste box 23 is provided at the bottom of the lower die base 2 corresponding to the accommodating hole 5. Specifically, the waste box 23 is used to collect waste cut when punching the plate.

[0026] like Figure 2 、 Figure 3 As shown, both the upper die base 1 and the lower die base 2 are provided with buffer rods. Specifically, the buffer rods are used to reduce the impact and noise during mold closing.

[0027] During specific use, the plate is placed on the profiling pin 4, and then the upper die base 1 moves down. The stripper plate 14 contacts the plate first under the action of the spring. As the upper die base 1 moves down, the first spring 12 is compressed, pressing the plate tightly against the profiling pin 4. Then, the profiling cavity 13 on the punching plate 9 cooperates with the profiling pin 4 to punch out the required shape and size of the plate. At the same time, the punching needle 16 cooperates with the accommodating hole 5 to punch out the required hole on the plate. Then, the upper die base 1 moves up, and under the action of the first spring 12, the stripper plate 14 is pushed to push the punched hardware out of the profiling cavity 13, making it easy to remove the punched hardware.

[0028] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
