METHOD FOR FORGING AXIALLY SYMMETRICAL BLANKS AND APPARATUS FOR ITS EMBODIMENT Russian patent published in 2001 - IPC

FIELD: plastic metal working, possibly in machine engineering for making axially symmetrical blanks by hot forging. SUBSTANCE: method comprises step of transporting blank along circular path by means of transporting member. Blank is moved from transporting member to die by means of punch, and blank is preliminarily clamped between punch and knocking out member. Then blank, punch and knocking out member are moved in common to die while simultaneously releasing transporting member and forging blank. After that forged blank is moved in reverse direction from die to transporting member remained in released state. Apparatus for performing the method includes upper plate with punch, lower plate with dies and knocking out members, walking disc with transporting members in the form of pair of spring-loaded jaws with fixing opening, and fixing members. Axis of fixing member is shifted relative to fixing opening at drawing jaws together. EFFECT: enlarged manufacturing possibilities. 3 cl, 11 dwg, 1 tbl, 1 ex
