Cold heading technology of cold heading machine

Cold heading machine is a special equipment mainly used for batch production of nuts, bolts and other fasteners

Cold heading process of cold heading machine:

(1) According to the theory of metal plastic deformation, a certain pressure is applied to the metal blank at room temperature to make it plastic deformation in the mold cavity, forming according to the specified shape and size.

(2) High quality metal materials with good "plastic deformation" must be selected, such as screw riveting steel, whose chemical composition and mechanical properties have strict standards.

(3) There are many models and series of cold heading bolt and nut forming machines. The equipment has reliable performance, high efficiency and stable product quality.

(4) The product has large forming and upsetting force, powerful configuration, and large input of equipment at one time. Therefore, the production specification below M24 is the most economical.

(5) It has good surface quality and high dimensional accuracy. Due to the cold work hardening in the upsetting process, the deformation should not be too large. Reduce cracking.

(6) Cold heading process is applicable to products with large batch and various specifications, so as to reduce costs.
