Description

Technical Field

[0001] The utility model relates to the technical field of hardware product production, in particular to a clamping device for hardware product production. Background Art

[0002] Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting. They are used to fix objects, process objects and decorate. The manufacture of hardware usually adopts casting, but it is more cost-effective to cast non-standard hardware. Usually, the blank is obtained by casting and then processed. During the processing, the clamping device is one of the components of the processing mechanism, and the clamping device plays a fixing role in the hardware processing process.

[0003] For example, the Chinese patent "A convenient hardware clamping device" with announcement number CN213615798U includes a box body, a box cover is arranged on the top of the box body, a moving plate 1 and a moving plate 2 are arranged on the top of the box cover, a moving slider is arranged on the bottom of the moving plate 1 and the moving plate 2, a slide groove matching the moving slider is arranged on the top of the box cover, and the moving slider is arranged inside the slide groove. The motor drives the screw rod 1 and the screw rod 2 to rotate, and then drives the moving plate 1 and the moving plate 2 to slide inside the box.

[0004] Although the above-mentioned prior art can achieve fixation during hardware processing, in actual use, on the one hand, after the hardware plate is pressed, it is necessary to manually push the hardware plate for the next pressing. Manually pushing the hardware plate cannot avoid errors in the finished product due to the deviation of the hardware plate, thereby reducing the yield rate. On the other hand, the adjustment of the clamping device is not flexible enough, and it is difficult to adjust the clamping device according to the size of the hardware plate, thereby reducing the adaptability of the clamping device. Therefore, it does not meet the existing needs. In this regard, we propose a clamping device for the production of hardware products. Utility Model Content
