Description

Technical Field

[0001] This utility model relates to the field of handle manufacturing technology, and more specifically, to a handle punching die. Background Technology

[0002] In manufacturing such Figure 1 When making the handle shown, punching and cutting are required. Since the handle is not a plane, it is difficult to support it. Therefore, the existing technology uses a step-by-step processing method, that is, punching and cutting are performed separately. The above processing method requires the handle to be processed multiple times, resulting in low production efficiency. Utility Model Content

[0003] This invention provides a handle punching die that overcomes some or all of the defects of the prior art.

[0004] According to the present invention, a handle punching die includes an upper die assembly and a lower die assembly that mutually compress and separate. The upper die assembly includes an upper die base, an upper clamping plate, and a stripper plate arranged sequentially from top to bottom along the height direction. The upper clamping plate is provided with multiple guide posts, and springs are sleeved on the guide posts. The stripper plate is used to move closer to and away from the upper clamping plate along the axial direction of the guide posts. The upper clamping plate is provided with multiple cutting punches and punching punches. The lower die assembly includes a lower die plate and a lower die base arranged sequentially from top to bottom along the height direction. Multiple mating components are provided between the stripper plate and the lower die plate, and the multiple mating components are used to clamp the handle.

[0005] Preferably, the mating assembly includes a first mating plate disposed on the side of the stripper plate away from the upper clamping plate, and a second mating plate disposed on the side of the lower mold plate away from the lower mold base. The side of the second mating plate close to the first mating plate forms a mating groove, which is used to mate with the handle.

[0006] Preferably, a plurality of first mating holes are formed at the upper clamping plate, the plurality of first mating holes being used to mate with the plurality of cutting punches, a limiting block is formed at the first mating hole, and a corresponding limiting protrusion is formed at the cutting punch, the limiting protrusion being used to abut against the limiting block.

[0007] Preferably, a first stripping hole is formed at the stripping plate corresponding to the mating hole, and the first stripping hole is used to slide with the cutting punch.

[0008] Preferably, the lower template forms a second mating hole corresponding to the first mating hole, and the lower mold base forms a third mating hole corresponding to the second mating hole.

[0009] Preferably, the punching punch includes a mounting part and a punching part. The upper clamping plate forms a countersunk hole corresponding to the mounting part. The mounting part is used to thread with the countersunk hole. The stripper plate forms a guide hole corresponding to the punching part. The guide hole is used to slide with the punching part.

[0010] Preferably, the lower template forms a fourth mating hole corresponding to the guide hole, and the lower mold base forms a fifth mating hole corresponding to the fourth mating hole.

[0011] Preferably, the lower mold base is provided with a plurality of first pads at intervals at the end away from the lower mold plate.

[0012] Preferably, a second pad is provided on the side of the first pad away from the lower mold plate, and at least one screw is provided at the second pad, which is used to pass through the second pad and the first pad and to engage with the lower mold base threadedly.

[0013] Beneficial effects: The cooperating components can clamp the handle blank, and the upper die component moves to the lower die component, so that the cutting punch and the punching punch can simultaneously squeeze the handle, thereby completing the cutting and punching operations at both ends of the handle. The spring can keep the stripper plate away from the upper clamping plate. That is, after the cutting and punching are completed, when the upper die component moves away from the lower die component, the stripper plate moves away from the upper clamping plate under the action of the spring, and the cutting punch and the punching punch retract into the stripper plate.

[0014] Furthermore, the cutting punch can be easily suspended at the first mating hole and fixed against the upper die holder. Since the cutting punch is prone to damage after long-term operation, this structure facilitates the replacement of the cutting punch without the need to replace the upper clamping plate, thereby improving production efficiency.

[0027] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0028] Seen in Figure 1-12 This embodiment provides a handle punching die, which includes an upper die assembly and a lower die assembly that squeeze and separate each other. The upper die assembly includes an upper die base 1, an upper clamping plate 2, and a stripper plate 3 arranged sequentially from top to bottom along the height direction. The upper clamping plate 2 is provided with a plurality of guide posts 4, and springs 41 are sleeved on the guide posts 4. The stripper plate 3 is used to move closer to and away from the upper clamping plate 2 along the axial direction of the guide posts 4. The upper clamping plate 2 is provided with a plurality of cutting punches 5 and punching punches 6. The lower die assembly includes a lower die plate 7 and a lower die base 8 arranged sequentially from top to bottom along the height direction. A plurality of mating components are provided between the stripper plate 3 and the lower die plate 7. The plurality of mating components are used to clamp the handle.

[0029] According to the solution provided in this embodiment, the cooperating component can clamp the handle blank and move the upper die component to the lower die component, so that the cutting punch 5 and the punching punch 6 can simultaneously squeeze the handle, thereby completing the cutting and punching operations at both ends of the handle. The spring 41 can keep the stripper plate 3 away from the upper clamping plate 2. That is, after the cutting and punching are completed, when the upper die component moves away from the lower die component, the stripper plate 3 moves away from the upper clamping plate 2 under the action of the spring 41, and the cutting punch 5 and the punching punch 6 retract into the stripper plate 3.

[0030] Seen in Figure 3 The mating components include a first mating plate 91 located on the stripper plate 3 away from the upper clamping plate 2, and a second mating plate 92 located on the lower template 7 away from the lower mold base 8. The second mating plate 92 forms a mating groove 921 on the side near the first mating plate 91, and the mating groove 921 is used to mate with the handle.

[0031] Specifically, the first mating plate 91 can clamp the handle, thereby facilitating the cutting punch 5 and the punching punch 6 to punch the handle.

[0032] Furthermore, a plurality of first mating holes 21 are formed at the upper clamping plate 2, the plurality of first mating holes 21 being used to mate with the plurality of cutting punches 5, a limiting block 211 is formed at the first mating hole 21, and a corresponding limiting protrusion 51 is formed at the cutting punch, the limiting protrusion 51 being used to abut against the limiting block 211.

[0033] With the above structure, the cutting punch 5 can be easily suspended at the first mating hole 21 and fixed against the upper die base 1. Since the cutting punch 5 is prone to damage after long-term operation, this structure facilitates the replacement of the cutting punch 5 without replacing the upper clamping plate 2, thereby improving production efficiency.

[0034] Among them, the stripper plate 3 forms a first stripper hole 31 corresponding to the mating hole, the first stripper hole 31 is used to slide with the cutting punch 5, the lower template 7 forms a second mating hole 71 corresponding to the first mating hole 21, and the lower mold base 8 forms a third mating hole 81 corresponding to the second mating hole 71.

[0035] In this embodiment, the punching punch 6 includes a mounting part 61 and a punching part 62. The upper clamping plate 2 forms a countersunk hole 22 corresponding to the mounting part 61. The mounting part 61 is used to thread into the countersunk hole 22. The stripper plate 3 forms a guide hole 32 corresponding to the punching part 62. The guide hole 32 is used to slide into the punching part 62.

[0036] With the above structure, the punch 6 can be installed on the upper clamping plate 2, and the punching part 62 can be telescopically engaged with the guide hole 32 to perform punching operations on the handle.

[0037] Furthermore, the lower template 7 forms a fourth mating hole 72 corresponding to the guide hole 32, and the lower mold base 8 forms a fifth mating hole 82 corresponding to the fourth mating hole 72.

[0038] Seen in Figure 2 Multiple first pads 101 are provided at intervals at one end of the lower mold base 8 away from the lower mold plate 7.

[0039] Furthermore, a second pad 102 is provided on the side of the first pad 101 away from the lower mold plate 7, and at least one screw is provided at the second pad 102. The screw is used to pass through the second pad 102 and the first pad 101 and to engage with the lower mold base 8.

[0040] Specifically, by setting the first pad 101 and the second pad 102, the upper die assembly and the lower die assembly can be buffered, thereby reducing the impact on the stamping equipment.

[0041] Working principle:

[0042] The upper die assembly is installed at the lifting part of the stamping equipment, and the lower die assembly is installed at the base of the stamping equipment. When punching the handle, the handle blank is first placed at the second mating plate 92 so that it fits with the mating groove 921. Then, the upper die assembly is controlled to move to the lower die assembly. When the first mating plate 91 abuts against the second mating plate 92, the upper clamping plate 2 continues to descend against the elastic force of the spring 41, so that the cutting punch 5 and the punching punch 6 extend out of the stripper plate 3 to cut and punch the handle. After that, the upper die assembly moves away from the lower die assembly, and the processed handle can be taken out. After that, the cutting waste is cleaned up, and the next handle processing operation can be carried out.

[0043] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0044] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
