摘要： Four-die forging device for forging presses can be employed to forge ingots and billets in a variety of steels and alloys on forging presses and is intended to provide for a longer repair-free service life of the device, a higher reliability, an increased forging process output and a better quality of forged parts. The holders (3, 4) of the side dies (5, 7) have a shape approximating to that of a truncated pyramid with the center of mass (47) of the "side die holder - side die" system located within the longitudinal section of the side die holder. The apart-guiding ways (9-12) are arranged either on the side surfaces of the die holders (1, 2), or on the inclined planes (22-29) of the holders (1-4) of the dies (5-8) in the longitudinal symmetry plane of the device, or on both of them. Internal planes of the apart-guiding ways are formed to enclose the planes of adjacent die holders thus creating a clutch-type connection. Provided in the bottom part of each side die holder are ledges (48, 49) whereagainst the antifriction plates (30-37) thrust. Working surface of each die at its cross-sectional area consists of a central working zone (52) and two side zones (53, 54). Maximum width of the die working surface (bmax) and the antifriction plate sliding surface length (1) are in a ratio of bmax/1 ≤ 1.5. The device is characterized by a longer repair-free service life, higher reliability, increased forging process output and better quality of forged parts.
