Abstract

PURPOSE: To stably form the shell of high accuracy by adding reciprocative ironing to the process of redrawing of shell working to apply reiterative tensile stresses over the both sides at the loading and releasing.
CONSTITUTION: Along with the progression of loading process, the surface of a shell 1 is smoothly finished as in burnishing by a die 11 having been set with an ironing weight 10 of a die, by which the surface layer is hardened and the fatigue characteristic of the blank is enhanced. At the releasing of load, the die 11 gives the deformation resembling to indentation in the form of slip contact to the material, thereby trimming the roughness of the shell 1 surface, evening the micro-undulations of the front and back surfaces such as shock lines observed at the re-drawing, and transferring the accuracy of a punch 12 accurately to the shell 1. This method yields the shell of higher dimensional accuracy and reduces the cost in work.
