Problems solved by technology

[0002] With the development of society, the demand for thin-walled and deep-hole parts is increasing. At present, most of the thin-walled and deep-hole parts are processed by forging. Apply deformation force to deform the round steel to obtain thin-walled deep-hole parts with certain shape, size and performance. However, the punches of most forging dies on the market are fixed connections, which cannot be flexibly installed, disassembled and replaced. The following problems are caused: first, different forging dies must be used when processing thin-walled deep-hole parts with different wall thicknesses, resulting in a large number of forging dies being idle, resulting in waste of resources; second, when the punch is worn or deformed and cannot be used, only Replacing the whole forging die, and changing the whole forging die at the same time causes a lot of waste of resources; third, when the punch is maintained, because the punch is connected with the whole forging die, it brings great inconvenience to the maintenance of the punch, which is not conducive to Post maintenance of punch
