Background Art

With the development of materials and technology, chairs have been made of various materials. However, metal is more popular due to its durability and smooth texture, which can better meet people's demand for durability. In the process of chair processing, a punching machine is needed to punch holes in the metal plate. The current chair production punching machine does not have the function of positioning the metal plate, which leads to inaccurate punching position and cannot feed the metal plate at a uniform speed. The staff has to load the materials, which is labor-intensive, time-consuming and inefficient. In addition, the punching head of the current chair production punching machine is fixed and cannot be adjusted as needed, which leads to a fixed punching position and cannot be flexibly adjusted, causing inconvenience in use. In view of this, in-depth research was conducted on the above-mentioned problems, and this case was created.
