The working principle of screw head machine

Date:2021-08-04Browse:127

The screw heading machine is a kind of cold heading equipment for manufacturing screws. Its main function is to form a metal processing machine for the basic shape of screws. It has the advantages of strong flexibility, easy length adjustment, and is suitable for mass production. The quality of the product is mainly related to the efficiency of its production and the technical proficiency of the operators.

There are two types of screw shape forming and thread forming: the equipment used for shape forming is a heading machine, which adopts cold heading forming method; the equipment used for thread forming is a thread rolling machine, which adopts extrusion forming method. It has better surface quality and higher dimensional accuracy. Because of the cold work hardening in the upsetting process, the amount of deformation should not be too large. Reduce cracking.
