Abstract
The invention discloses a forging device and a forging method of a braking piston. The forging device of the braking piston comprises a guide die sleeve, a forming punch, a die and a material-returning punch. The forming punch is assembled into the guide die sleeve. The guide die sleeve is matched with the die in order to ensure coaxiality of a product. Coaxiality is achieved between the material-returning punch and the forming punch. The material-returning punch is arranged at the lower end of the forming punch. The forging device and the forging method of the braking piston have following beneficial effects: an air outlet groove of the braking piston is formed by machining during forging so that groove-milling operation to forged blanks is reduced; production efficiency is increased; and manufacture cost is decreased.
