Basic Introduction Of Cold Heading Machine

Cold forging bolts and nuts forming machines have many models and series. The equipment has reliable performance, high efficiency and stable product quality.

Within the allowable range of the cold heading diameter of the cold heading machine, the position of the clamp (screw in or out) can be adjusted according to the required size of the anchoring head to obtain a suitable amount of rebar (wire) extension; ) The area of 120～130mm of the cold heading part must be derusted and straightened.

Basic introduction of cold heading machine:

• The product has high forming and upsetting force, equipped with power, and large equipment investment at a time. Therefore, the production specification of cold heading machine below M24 is the most economical.

• The cold heading machine 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.

• The cold heading process is applicable to products with large batches and various specifications, so as to reduce costs.

• According to the theory of metal plastic deformation, a certain pressure is applied to the metal blank at room temperature to cause plastic deformation in the mold cavity, and the cold heading machine is shaped according to the specified shape and size.
