| Abstract: | This paper is devoted to the basic principle of plastic forming .The finite element analysis was fully utilized to the research of three issues ,namely the variation of the load on the screw drilling tool joint with the change of the deformation of the work-piece in heat upsetting extrusion ,the surface stress of the work-piece ,as well as the metal flow of the work-piece in the process of forming .And then ,the requisite upsetting extrusion pressure and molding temperature of screw drilling tool joint concerning heat upsetting extrusion were defined .The basic structure of the upsetting extrusion forming device was subsequently designed .In short , it is concluded that the processing method of screw drilling tool joint is highly feasible by experiment . |
