Abstract：
|
|
The forming characteristics of the location eccentric shaft was analyzed.According to the characteristics of cold and warm extrusion,the forming technology plan combining cold with warm extrusion was adopted.The extrusion forming drawing was made and the extrusion procedure route was confirmed.The deformation degree of each extrusion procedure was checked.The cold and warm extrusion dies were introduced.The conclusion is that the forming technology combined cold with warm extrusion can be used for the parts with high dimension precision and large deformation degree.Meanwhile,before warm extrusion,it must prearrange material rationally so as to guarantee the full forming of the part.Considering the blank was influenced by many factors during warm extrusion,the cold push-extrusion procedure can be adopted for assuring the high dimension precision of key positions of the part.
