METHOD OF HOT SIMULTANEOUS STAMPING OF ROUND IN PLAN FORGED UNITS

摘要

The inventive method includes heating the initial blank, pellet, forming double placed one inside the other forging, trimming the outer oblo forgings and forgings inner cutting, punching holes in the inner forgings. After precipitation lead preforming dual forgings, finally forming an outer and forging to give semifinished inner cylindrical shape forgings predetermined volume with N, 1-2,5, where aspect ratio H - semifinished size adjustment; d - the inner diameter of the outer forgings. In this final forming of the inner forging is carried out in the additional stream die simultaneously with pre-draft subsequent original billet. 1 z.p.f BACKGROUND 9 yl. Since CO
