I. Introduction
Production practice proves that hot extrusion is a metal pressure processing method with high production efficiency, low labor intensity, good processing quality, material saving, labor saving and low cost. This advanced processing method can replace or partially replace the metal cutting process, creating conditions for machining to achieve less cutting. Now, the CA10B universal joint bearing sleeve is taken as an example to introduce its hot extrusion die design.
Figure 1 is a product part drawing of the CA10B universal joint bearing sleeve, the material is 15Mn. From the shape of the part, the part should be back-extrusion process; from the dimensional accuracy and surface roughness requirements of the part, it exceeds the requirements that can be achieved by hot extrusion. Therefore, a certain machining allowance should be placed to keep it. Machining after hot extrusion.
