Cold heading machine technology
Release time:2019/6/21 17:23:40
Modern cold heading machine has been increased from simple two-station to multi-station. At present, there are 5-mode, 6-mode and 6-mode lengthened cold heading machines in China.
(1) The upsetting force of the product is large, the power is in the configuration, and the equipment is put in a large amount at one time. Therefore, the production specifications below M24 are economical.
(2) Cold upsetting machine technology can be applied to large-scale products of various specifications, so as to reduce costs.
(3) There are many models and series of cold heading bolt and nut forming machines. The equipment has high efficiency, reliability and stable product quality.
(4) According to the theory of metal plastic deformation, a certain pressure is applied to the metal blank at room temperature to produce plastic deformation in the die cavity, and the blank is shaped according to the prescribed shape and size.
(5) It is necessary to select high quality metal materials with good plastic deformation, such as rivet steel, whose chemical composition and mechanical properties have strict standards.
(6) It has better surface quality and higher dimensional accuracy. Because of cold work hardening in upsetting process, the deformation should not be too large. Reduce cracking.
