Abstract:

As servo deep drawing technology produces a great impact on the deep drawing effectiveness and efficiencyof 304 stainless steel,a servo deep drawing process curve of 304 stainless steel is established by extractingthe constraint conditions of the curve based on the mechanical and servo deep drawing properties of press.Then,the orthogonal simulation experiment of the curve meeting conditions is performed,thus achieving an ideal targetprocess curve.Finally,the deep drawing experiments of 304 stainless steel are performed through the servo controlsystem and the process-programming free curve mode on a servo crank press,thus verifying the feasibility of freecurve mode.The results show that，under the conditions of servo and programming the proposed free curve modecan produce an ideal deep drawing effect on the materials which are difficult to mold .

Key words: 304 stainless steel, servo deep drawing, process curve planning, free curve mode
