Description

Technical Field

[0001] This utility model relates to the technical field of punching devices, and in particular to a punching device for wrench production. Background Technology

[0002] A wrench is a common tool for installation and disassembly. It uses the lever principle to tighten or loosen bolts, screws, nuts, and other threaded parts. Wrenches typically have openings or sockets at one or both ends of the handle to hold the threaded parts. When using a wrench, external force is applied to the handle in the direction of thread rotation to tighten or loosen the threaded parts. Currently, manufacturers generally punch holes in wrenches during the production process. A punching device is a mechanical device that, after the wrench is fixed in place, uses a power mechanism to drive a punching die (such as a punch) to apply pressure to the wrench and complete the punching process.

[0003] Chinese utility model CN217018201U discloses a punching device with a protective structure for easy fixing in wrench processing. The protective structure is designed with a connecting block on the outside of the hydraulic rod. By controlling the protective cover to fit on the outside of the hydraulic rod, and then using the disassembly and connection plate, the protective cover can be fixed on the outside of the hydraulic rod, which can play a protective role during the punching process.

[0004] However, the existing device obstructs the stamping block during use, making it difficult to observe whether the wrench is aligned with the stamping block. Therefore, a sliding protective cover was designed to address the above-mentioned problem, making it easier to use. Utility Model Content

[0026] The current technology involves a connecting block on the outside of the hydraulic rod. A protective cover is fitted over the hydraulic rod, and then fixed to the outside of the hydraulic rod by a detachable connecting plate, providing protection during the stamping process. However, this existing device obstructs the stamping block, making it difficult to observe whether the wrench is aligned with the stamping block.

[0027] As shown in the attached drawings, this embodiment of the invention provides a punching device for wrench production.

[0028] The device includes: a workbench 11 with a support 12 fixedly mounted on its top; a stamping rod 13 fixedly mounted on the support 12; a protective assembly 2 on the top of the workbench 11, the protective assembly 2 including: a slide groove 21 formed on the top of the workbench 11; a slider 22 slidably disposed inside the slide groove 21; a first protective cover 23 disposed on the top of the workbench 11 and fixedly connected to the slider 22; a second protective cover 24 disposed on the top of the workbench 11 and fixedly connected to the slider 22; one end of a connecting rod 25 rotatably connected to both the first protective cover 23 and the second protective cover 24; and one end of a telescopic motor 26 passing through the support 12 and fixedly connected to the support 12, with its output shaft rotatably connected to the other end of the connecting rod 25.

[0029] Specifically, the stamping rod 13 consists of a hydraulic rod and a stamping block. The hydraulic rod controls the stamping block to move downward, which can stamp the workpiece. The hydraulic rod is used in conjunction with an oil pump, which is existing equipment and is not shown in the attached drawings.

[0030] In use, simply place the wrench workpiece to be stamped on the top of the worktable 11. The protruding block restricts its position, aligning it with the stamping rod 13. Then, connect the telescopic motor 26 to an external power source, extending the motor and pushing the connecting rod 25 to rotate. As the connecting rod 25 rotates, it pulls the first protective cover 23 and the second protective cover 24 closer together. At the same time, the slider 22 slides inside the groove 21 until the first protective cover 23 and the second protective cover 24 align, enclosing the bottom end of the stamping rod 13 and one end of the workpiece. Then, use the stamping rod 13 to stamp the workpiece. Scrap will fall from the bottom of the worktable 11. Then, control the telescopic motor 26 to retract, causing the connecting rod 25 to rotate, separating the first protective cover 23 and the second protective cover 24, and removing the workpiece.

[0031] In some embodiments, both the first protective cover 23 and the second protective cover 24 are made of transparent material.

[0032] The transparent material design makes it easier to observe the inside of protective shield 1 23 and protective shield 2 24.

[0033] In some embodiments, the protective component 2 further includes a ball bearing 221 disposed on the inner side of the slider 22.

[0034] The design of ball 221 can reduce the friction between slider 22 and groove 21.

[0035] In some embodiments, the protective component 2 further includes a rubber strip 27 fixedly disposed on the inner sidewall of the top of the first protective cover 23 and the second protective cover 24.

[0036] The design of the rubber strip 27 can prevent the stamping rod 13 from being scratched when the protective cover 1 23 and the protective cover 24 are connected.

[0037] In some embodiments, the protective component 2 further includes: a groove 28 formed on one side of the first protective cover 23; and a protrusion 29 fixedly disposed on one side of the second protective cover 24.

[0038] The design of the groove 28 and the ridge 29 allows the ridge 29 to be inserted into the groove 28 to reduce the gap when the protective cover 1 23 and the protective cover 24 are connected.

[0039] In some embodiments, a collection assembly 3 is provided at the bottom of the workbench 11. The collection assembly 3 further includes: an L-shaped plate 31 fixedly disposed at the bottom of the workbench 11; a collection box 32 disposed at the bottom of the workbench 11; and protrusions 33 disposed on both sides of the collection box 32, through which the collection box 32 is slidably connected to the L-shaped plate 31.

[0040] Before use, the collection box 32 is slidably connected to the L-shaped plate 31 using the protrusion 33, and the collection box 32 is installed at the bottom of the workbench 11 for easy collection of waste materials.

[0041] In some embodiments, the protrusion 33 is rotatably connected to the collection box 32.

[0042] The rotating connection reduces friction, making installation and disassembly smoother.

[0043] In some embodiments, the collection assembly 3 further includes: a positioning plate 34 fixedly disposed on one side of the collection box 32; and a pin 35 with its bottom end penetrating through the workbench 11 and inserted into the inner side of the positioning plate 34.

[0044] The connection between the positioning plate 34 and the pin 35 can stably restrain the collection box 32 at the bottom of the worktable 11.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
