一、基本概念冷挤压是机械制造工艺中少切削、无切削加工新工艺之一。它是将冷挤压模具装在压力机上,利用压力机简单的往复运动,使金属在模腔内产生塑性变形,从而获得所需要的尺寸、形状及一定性能的机械零件;冷挤压是在室温条件下进行的,不需要对毛坯进行加热。冷挤压工作可以在冷挤压压力机上进行,也可以在一般的机械压力机(冲床)上 First, the basic concept of cold extrusion machinery manufacturing process less cutting, non-cutting one of the new process. It is the cold extrusion die mounted on the press, the use of simple reciprocating presses, the metal in the cavity plastic deformation, resulting in the required size, shape and mechanical properties of a certain performance; cold extrusion is in the Room temperature conditions, the blank does not need to be heated. Cold extrusion work can be carried out in the cold extrusion presses, but also in general mechanical presses (punch)
