Upper forming method of free forging hammer with angle long rod type forge piece

The invention discloses an upper forming method of a free forging hammer with an angle long rod type forge piece. The method comprises the following steps of 1, designing a forge piece; 2, designing atire mold; and 3, forging a round bar on the free forging hammer, and finally obtaining a qualified forge piece. In the step 2, in the design process of the forge piece, the machining allowance is uniformly given along the shape of a part and the part is designed into a cuboid forge piece with a certain angle which is consistent with the appearance of the part, the angle of the forge piece and the angle of the part are a degrees, and namely, the forge piece is absolutely parallel to the part; and in the step 2, the tire mold comprises an upper tire mold and a lower tire mold, the lower end ofthe upper tire mold is provided with a protruding angle, the upper end of the lower tire mold is provided with a recessed angle, the angles of the upper tire mold and the lower tire mold are both a degrees, the protrusion is
