Description

Technical Field

[0001] The utility model relates to the technical field of cold heading machines, in particular to a cold heading machine for processing steel balls. Background Art

[0002] A cold heading machine is a machine used to process metal materials. It is used to create threads and other shapes of metal parts. The working principle of a cold heading machine is to press the metal material into the desired shape at room temperature, rather than by heating the material to shape it. This makes the cold heading process more energy-efficient, more cost-effective, and more suitable for workpieces of certain shapes and sizes;

[0003] In the prior art, when the cold heading machine is started, the workpiece is pushed to the position of the upsetting pin, and the upsetting pin molds the metal material into the desired shape by applying pressure. This process is completed at room temperature, so it is called "cold" upsetting. After upsetting, the metal material is formed into the desired shape. The accuracy and quality of these shapes depend on the design of the upsetting pin and the adjustment of the machine. After upsetting, the workpiece is removed from the cold heading machine and further processed to meet the requirements of the final product.

[0004] In the prior art, the cold heading machine does not screen the steel balls. The unscreened steel balls will have different degrees of surface roughness. Due to uneven pressure and wear during the processing, the surface quality of some steel balls is not ideal, affecting the appearance and performance of the product. Therefore, a cold heading machine for steel ball processing is proposed to solve the above problems. Utility Model Content
