Wenzhou Ouhai Sanyang Transmission Machinery Factory cold upsetting machine is a special equipment mainly used for batch production of nuts, bolts and other fasteners

(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 regular shape and size.

(2) It is necessary to select high-quality metal materials with outstanding "plastic deformation", such as rivet screw steel, whose chemical composition and mechanical function have strict standards.

(3) There are many types and series of cold heading bolt and nut forming machines. The equipment features reliable functions, high efficiency and stable commodity quality.

(4) The product has large upsetting force, powerful equipment, and large investment in equipment at one time. Therefore, the production standard below M24 is the most economical.

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

(6) The cold heading technology is applicable to the products with large batches and various standards, so as to reduce the cost.
