摘要

1. A method for the design of parts, containing! a first step in which the computer performs the analysis punching based on the shape extruded article or shape of the part, the pressing force preform, friction coefficient, material strength tensile yield strength ratio between stress and strain and the sheet thickness as a forming conditions for calculating the distribution of sheet thickness and strain distribution after punching in a stamped product, and! a second step in which the computer analyzes the operating characteristics based on the distribution of the plate thickness, strain distribution after punching and form extruded articles or shape of the part as a state extruded product parameters for calculating operating characteristics of the items,! wherein the computer repeats the calculation performed during the first phase of the second stage, a predetermined number of times to change at least one of the conditions for forming the optimum output forming conditions, which gives the maximum value or the target value of the operational characteristics. ! 2. A method of designing parts according to claim. 1! wherein forming conditions further include at least one kind or two kinds or more selected from the shape of the material before forming, the tool shape and the stroke length. ! 3. The method of designing parts according to claim. 1! wherein the computer performs the analysis for additional punching calculating stress distribution after punching and! wherein the computer analyzes the operating characteristics of the extruded product to further Ba
