The company has developed a die forging hydraulic press for the wheel axle of an integral upsetting motor car, which is composed of an upper bending die, a lower bending die, an upper bending cylinder, a lower bending cylinder, an upsetting cylinder, a movable beam, a left and right upper function box, a left and right lower function box, a left and right lower function box moving cylinder, and a movable workbench. Its characteristics are: the lower bending cylinder is fixedly connected with the center of the lower beam, and the top of the piston of the lower bending cylinder is fixedly connected with a connecting nut, The upper end of the connecting nut is radially provided with a T-shaped through groove, and the T-shaped through groove of the connecting nut is inserted with the T-shaped block at the lower end of the top mold rod. Beneficial effect: it meets the technological requirements of upsetting the whole train axle, and provides a special hydraulic press for precision die forging the train axle. It can not only realize the upper and lower vertical mold locking protection force controlled by hydraulic pressure, but also realize two opposite horizontal force increases.
