Cold heading machine cold heading process

Cold heading machineIt is a special equipment mainly used for mass production of fasteners such as nuts and bolts.

Cold heading machine cold heading process:

(1) According to the metal plastic deformation theory, apply a certain pressure to the metal blank at room temperature to cause plastic deformation in the mold cavity and form according to the specified shape and size

(2) It is necessary to select high-quality "plastic transformation" metal materials, such as riveted screw steel, with strict standards for their chemical composition and mechanical properties.

(3) Cold heading bolts and nut forming machinery have multiple models and multiple series of machine types. The equipment performance is reliable, the efficiency is high, and the product quality is stable.

(4) The product forming and forging force is large, the configuration power is high, and the equipment is invested at one time. Therefore, the production specifications below M24 are the most economical.

(5) Have good surface quality and high dimensional accuracy. Due to the cold hardening during the upsetting process, the deformation should not be too large and cracking should be reduced.

(6) The cold heading process is applicable to products of large batches and various specifications, so as to reduce costs.

Modern cold heading machines have been added from the past simple 2 stations to multiple stations. Currently, the newer varieties in China are 5-mode 6-mode 6-mode lengthened cold heading machines.
