Introduction
Is a non cutting processing equipment, which has the advantages of high production efficiency, simple process, easy operation, saving raw materials, stable quality and so on. It uses hydraulic technology to send the diameter reducing part of round steel into the inner cavity of special die for cold shrinkage and compression molding. The steel density of the shrinkage part can be greatly improved, so as to improve the tensile strength of the material. The plasticity and impact toughness are not reduced, so that the strength of the screw thread part and the rod body part is consistent, which solves the disadvantage of reducing the tensile force and impact toughness due to lathe peeling.
