Title: Method of determining outline of jig for self- hardening mold
Inventor: HARORUDO EMU BURUWAA JIYUNIA
IPC: B21D26/047
Filed: 1992-01-14
Abstract: PURPOSE: To reduce residual stresses in age-formed parts by predicting from a stress relaxation curve, the value of an applied strain applicable to an unformed member at the time of age-forming, and thereby obtaining a residual strain for manufacturing a member of a desired shape. CONSTITUTION: Test piece sets of the same thickness are each restrained for age-forming on the forming jigs 58 having different radii of curvature. A residual strain value is positioned on a graph for each test piece. A stress relaxing curve is formed on the graph and expressed as a numerical formula. At age- forming, the value of an applied strain to be applied to an unformed member is determined by the strain relaxation curve, thus, the value necessary for manufacturing a member in a desired complex shape is obtained. For the formation, a die 54 with a cavity 56 is fitted and used by combining it with the forming jigs 58. Individual parts 20 are placed on the die 54 and formed. As a result, the contour of the age-forming jigs can be determined for the purpose of improving for example the yield of formed articles.
