Half shaft blank forging and pressing die

The invention belongs to the technical field of forging dies, and particularly relates to a half shaft blank forging and pressing die which comprises a large-diameter die and a small-diameter die and is characterized in that the large-diameter die comprises a first upper casting die and a first lower casting die, the small-diameter die comprises a second upper casting die and a second lower casting die, and a forge piece guiding and positioning device is arranged between the first lower casting die and the second lower casting die. According to the forging and pressing die, the two falling dies are combined, the guide devices are arranged on the side faces of the two falling dies, the coaxiality of forgings is increased, meanwhile, the extrusion and stretching device is used for reducing the movement amount of the axis of the forgings during forging and pressing, and the movement amount of the surfaces of the forgings is increased. 本发明属于锻造模具技术领域，具体是指一种半轴坯件锻压模具，包括大径模具和小径模具，其特征在于：大径模具包括第一上摔模和第一下摔模，小径模具包括第二上摔模和第
