Abstract
According to the relationship between the direction of metal flow and punch heading,the extrusion can be divided into forward extrusion,inverted extrusion and compound extrusion.This passage discusses the metal flow features of extrusion and the influencing factors,the structure and performance of the extrusion workpiece.Take the pole compound extrusion as the example,the article studies the stress-strain of the pole compound extrusion,then calculates the extrusion pressure in details by using the engineering law.On these basises,analysis the process of the extrusion product and make its technology program.Finally,design the corresponding die,draw its diagram,and selects the materials of some important part of the die.
