Description

Technical Field

[0001] The utility model relates to the technical field of punching holes in hardware products, in particular to a punching device for hardware products. Background Art

[0002] Hardware products refer to tools made by processing and casting metals such as gold, silver, copper, iron, and tin, which are used to fix objects, process objects, and decorate. The manufacture of hardware products usually adopts the casting method, but the casting method of non-standard hardware products is more cost-effective. Usually, the blank is obtained by casting and then processed. During the processing, the punching device is one of the components of the processing mechanism. The punching device plays the role of opening holes in the hardware products during the processing of hardware products.

[0003] For example, the Chinese patent "A Punching Equipment for Hardware Moulds" with announcement number CN219233999U includes a workbench, and a moving mechanism and a flushing mechanism are arranged on the top of the workbench. The moving mechanism includes a first motor, and a screw is arranged on the right side of the output end of the first motor. Two groups of first threaded sleeves are screwed on the outer wall of the screw, and a support plate is arranged on the front side of the first threaded sleeve. Water leakage holes are evenly opened on the top of the support plate, and a slide groove is opened through the top of the support plate. A bidirectional screw is arranged in the slide groove, and two groups of second threaded sleeves are evenly screwed on the outer wall of the bidirectional screw. Both groups of second threaded sleeves are arranged in the slide groove, and a clamping plate is arranged on the top of the second threaded sleeve, a guide block is arranged at the bottom of the support plate, and a second motor is arranged on the left side of the support plate. The flushing mechanism is located on the outer wall of the support plate and cooperates with the support plate.

[0004] Although the above-mentioned existing technology can realize punching of hardware products, in actual use, on the one hand, the debris generated after the punching of the hardware products is difficult to clean, and the debris will accumulate and adhere to the hardware products, resulting in dents and flaws on the surface of the hardware products, thereby affecting the appearance of the hardware products. On the other hand, after completing one punching of the hardware products, it is necessary to manually push the hardware products for the next punching. Manually pushing the hardware products is difficult to avoid errors in the punching position due to the deviation of the hardware products. Therefore, it does not meet the existing needs. In this regard, we propose a hardware punching device. Utility Model Content

At the same time, the rotating rod is moved in the vertical direction inside the fixed rod through the external thread of the rotating rod. At the same time, the rotating rod drives the mounting rod and the brush to move in the vertical direction together, so that the height of the brush can be adjusted according to the thickness of the hardware products, thereby improving the adaptability of the cleaning device.

[0019] 3. The utility model can adjust the position of the drill bit in the horizontal direction through the linear guide rail and the sliding block. When one punching is completed, when the next punching operation is performed on the same piece of hardware, the first motor is turned on, so that the output shaft of the first motor drives the pulley to rotate on the linear guide rail. At this time, the pulley drives the sliding block to move, and the sliding block drives the drill bit to move in the horizontal direction, which is convenient for the movement of the drill bit and prevents the situation where the punching position has errors due to the deviation of the hardware products caused by manual pushing of the hardware products.
