PART FORMING METHOD Russian patent published in 1997 - IPC

FIELD: plastic metal working, namely, part shaping in motor industry and other branches of machine engineering. SUBSTANCE: method involves distributing deformation on small radius portions of part according to technological stages determined by calculation of deformation deformation intensity for each technological transition; calculating radius value according to deformation intensity , where R_final is radius of final dimension (according to drawing); ε_еfinal is deformation intensity at final forming operation; εре

_trans is designed deformation intensity on radius portion determined for each transition εре = ε_e/m; εadm.efinal is admissible deformation intensity on radii portion determined for each technological transition and at calculation ε^е/m; n is number of operation used for deformation distribution; m is quantity of transitions for which deformation distribution is used. EFFECT: enhanced efficiency. 2 dwg, 1 tbl
