Abstract:Abstract. Based on the characteristic distortion and the influence factors of cone parts by cold extrusion, cold extrusion process of a center hole conical part is simulated by Abaqus software, then the shape of the hole generatrix after cold extrusion is obtained by this method. According to simulation, the relation between the initial parameters of a center hole conical part with the hole generatrix after cold extrusion is built, and it provides a theoretical basis for the application of cold extrusion proce… Show more
