Novel finish forging die for end face tooth flange yoke forge piece

Abstract

The utility model discloses a novel finish forging die for an end face tooth flange yoke forge piece, which comprises an upper pressing die and a lower fixed die, a finish forging die cavity is defined between the bottom surface of the upper pressing die and the top surface of the lower fixed die, the finish forging die cavity comprises an upper cavity arranged on the bottom surface of the upper pressing die and a lower cavity arranged on the top surface of the lower fixed die, an upper bulge is arranged in the middle of the upper cavity along the left-right direction, and a lower bulge is arranged in the middle of the lower cavity along the left-right direction. Upper pressing blocks are arranged on the left side and the right side of the upper bulge on the bottom surface of the upper pressing die; a lower protrusion is arranged in the middle of the lower cavity in the front-back direction, a left fork lug cavity and a right fork lug cavity are formed in the finish forging die cavity and located on the left side and the right side of the lower protrusion respectively, and lower pressing grooves are formed in the top face of the lower fixed die and located on the left side of the left fork lug cavity and the right side of the right fork lug cavity. The upper cavity of the upper pressing die and the lower cavity of the lower fixed die are optimized and improved, demolding is easier, it is guaranteed that the outer side face of the fork lug is free of material shortage, the strength of the fork lug is improved, the area of the tooth face structure of the disc part is larger, and the service life of the end face tooth flange fork is prolonged.
