| Abstract: | The position of the first support of a workpiece in a die cavity and maximum deflection of the workpiece are obtained based on the specific features of plastic deformation of the metal in a die. The minimum depth of conical die and the relationship between coning of die cavity and workpiece length are determined;By the conditions of plastic stability of a column, the critical coning of die cavity is derived. conditions under which plastic instability can be avoided during upsetting are proposed. |
