The Research of the Cold Extrusion Shaping Technology of the Tubular Component with Oral Part Having Flange

摘要

In the basis of researching the shaping methods to the tubular component with oral part having flange, the varieties of feasible forming process schemes are analyzed comprehensively under the premise of ensuring not rupture, with combination of many forming processes such as cold extrusion, cold stamping and upsetting. In the middle of cold extrusion shaping of the tubular component with oral part having flange, in the light of solid blank selected, the varieties of technology schemes that are utilized flexibly in the production are proposed and the problems existed in the schemes are compared and analysed and the corresponding prevention and improvement measures are put forward. In the production of the tubular component with oral part having flange, the cold extrusion technology is used to give the reference to a certain extent to the similar parts of forming process and die design.
