[0002] Screws are also called screws. Screws are tools that use the physical and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually fasten objects and parts. Screws are a general term for fasteners and a daily colloquialism. Screws are indispensable industrial necessities in daily life: such as very small screws used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large screws and nuts are used; transportation equipment, airplanes, trams, cars, etc. use both large and small screws.

[0003] In the process of processing large screws, a heading machine is needed to shape the screw head. However, the existing equipment needs to continuously move the screws when shaping the screw heads, and the screws need to be taken and placed manually. If such a transfer method is not timely, it is very easy to cause waste, affecting the processing efficiency of the screws. For this reason, we propose a heading machine with a low scrap rate for processing screws. Utility Model Content
