PURPOSE:To enable transferless forging by moving vertically the upper and lower dies with the state of the burr part being borne one a base stand after closed die forging then by trimming with progressing the forging article to the next stage with its suspension on the base stand by the burr part. CONSTITUTION:The bar stock 21 heated by a heater 18 is transferred among the roughing dies 6', 6 of the upper and lower bolsters 1, 2, finishing dies 7', 7 and burr drawing dies 8', 8 at fixed stroke by transfer rolls 12, 14' and forging is performed in order. The forged bar stock 22 is propressed to the next stage with being suspended on the base stand with the burr part and finally the burr part is cut off by burr cutting edges 9', 9 and fallen into burr chute 11. The transferless forging of bar stock is thus enabled.
