What is the difference between hydraulic press and cold extrusion forming hydraulic press?
cold extrusion forming hydraulic pressIt is a kind of hydraulic press. Cold extrusion is to put the metal blank in the cold extrusion die cavity. At room temperature, the punch fixed on the hydraulic press applies pressure to the blank to make the metal blank produce plastic deformation. Obviously, the cold extrusion is to control the metal flow by the die and to form the part by a large number of metal volume transfer.
In terms of extrusion equipment, China has the ability to design and manufacture all levels of tonnage extrusion press. In addition to the general mechanical press, hydraulic press, cold extrusion press, but also successfully used friction press and high-speed high-energy equipment for cold extrusion production.
如果毛坯不经加热就进行挤压，便称为冷挤压。冷挤压是无切屑、少切屑零件加工工艺之一，所以是金屑塑性加工中一种先进的工艺方法。山东众友重工机床有限公司可根据用户需求量身定制专用冷挤压成形液压机设备。冷挤压成形液压机定制热线13562463338（同微信号）。
At present, cold extrusion technology has been widely used in fasteners, machinery, instruments, electrical appliances, light industry, aerospace, shipbuilding, military and other industrial sectors, and has become one of the indispensable important processing means in metal plastic volume forming technology. With the progress of science and technology and the continuous improvement of product technology requirements in automobile, motorcycle, household appliances and other industries, cold extrusion production technology has gradually become the development direction of fine production of small and medium forgings.
