The cold heading machine is a special equipment mainly used for mass production of nuts, bolts and other fasteners. The earliest cold heading machine in the world originates from Germany. At that time, the purpose of the cold heading machine was mainly for the mass production of bullet shells during World War II.
Cold heading processing
(1) According to the theory of metal plastic deformation, a certain pressure is applied to the metal blank at normal temperature to cause plastic deformation in the mold cavity, and is shaped according to the prescribed shape and size.
(2) Choose high-quality "plastic deformation" good metal materials, such as rivet screw steel, because of its strict standards of chemical composition and mechanical properties.
(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 upsetting force, and the configuration power is large. Therefore, the production size below M24 is the most economical.
(5) It has better surface quality and higher dimensional accuracy. Because of the cold work hardening during the upsetting process, the amount of deformation should not be too large. Reduce cracking.
(6) The cold heading process is applicable to products with large batches and various specifications, so as to reduce costs. The modern cold heading machine has been increased from the simple two stations in the past to multi-stations. The newer domestic varieties are the 5 mode 6 mode 6 mode extended cold heading machine.
