Study on Mapping of Forming Precision of Workpiece to Stiffness of Hydropress Frame
Determination of the stiffness specification is essential to subsequent structure design of a hydropress. Through the analysis of the press-die-workpiece system, it is found that the forming precision of the workpiece is significantly affected by the deflection of the lower beam of press frame. According to this finding, a mapping model between the forming precision of the workpiece and the stiffness of the lower beam is established. With this mapping model, the forming precision of the workpiece can be mapped into the stiffness requirement of the lower beam to form the stiffness specification of the hydropress frame.
