Background

The extrusion die is a press working method in which a punch or a punch is used to press a billet placed in a die to cause plastic flow, thereby obtaining a product corresponding to the shape of a hole or a female die of the die. The extrusion, especially the cold extrusion, has high material utilization rate, improved structure and mechanical property of the material, simple operation and high production efficiency, can be used for manufacturing long-rod, deep-hole, thin-wall and special-shaped section parts, and is an important machining process with few or no cutting. Extrusion is mainly used for forming metal, and can also be used for forming nonmetal such as plastic, rubber, graphite and clay blanks. France in the 17 th century uses a manual screw press to extrude a lead pipe which is used as a water pipe and starts cold extrusion. The cold extrusion of zinc, copper and copper alloys was achieved at the end of the 19 th century, expanding to the extrusion of aluminum and aluminum alloys in the early 20 th century. The German people in the 30 s invented phosphorized and saponified surface antifriction lubricating treatment technology to make cold extrusion of steel successful, and originally used for extruding steel cartridge case. After the second world war, cold extrusion of steel has been generalized to other countries and expanded the range of applications. Hot extrusion of steel was applied and developed in the metallurgical and mechanical industries, starting in the 50 s with the molten glass lubrication method.
