[0002] A cold heading machine is a special equipment mainly used for batch production of fasteners such as nuts and bolts. It is a special cold heading equipment for producing hexagonal nut blanks. The material on the bar stock is fed through roller wheels, and then undergoes five processes of cutting, ball pressing, angle pressing, punching, and forming in sequence, which can be automatically completed by one machine. It is suitable for batch or professional production of nut standard part manufacturers and large and medium-sized enterprises that use a large number of standard nut parts.

[0003] For a cold heading machine, since it needs to perform five processes of cutting, ball pressing, angle pressing, punching, and forming, the dies are all installed in a linear arrangement, and generally the outer tube of the die is cylindrical.

[0004] When installing the die of the existing cold heading machine, generally, the die is directly fixed horizontally on the mounting base through bolts. At this time, the end of the die faces the stamping end, and the distance between the two is small. Therefore, when installing and disassembling, the operating space is small and the loading and unloading are very laborious. Summary of the Utility Model
