Four-die forging device for forging presses comprising: - top- and bottom die holders (1, 2) for holding a top and a bottom die having inclined planes for operationally interconnecting thereto side die holders (3, 4) having inclined planes which correspond to the respective inclined planes of the top- and bottom die holders (1, 2) and being arranged so that they are movable relative to top- and bottom die holders (1, 2) while being interconnected thereto by means of the apart-guiding ways; - antifriction plates arranged on the inclined planes of the die holders and four dies with working surfaces; wherein the side die holders (3, 4) have a shape approximating to that of a truncated pyramid; - in a first alternative, apart-guiding ways are arranged on the side surfaces of die holders, which amounts at least four apart-guiding ways; - in a second alternative, apart-guiding ways are arranged on the inclined planes of the die holders in the longitudinal symmetry plane of the device, which amounts at least two apart-guiding ways; - in a third alternative, apart-guiding ways are arranged on the side surfaces and on the inclined planes of the die holders in the longitudinal symmetry plane of the device, which amounts at least six apart-guiding ways; - internal planes of said apart-guiding ways being formed to enclose the planes of adjacent die holders or elements rigidly secured on said die holders thus creating a clutch-type connection; characterized in that - the centre of mass of the "side die holder (3, 4) - side die " system is located within the limits of a side die holder (3, 4) longitudinal section; - in the bottom part of inclined plane of each side die holder (3, 4) respective ledges (48, 49) are provided, whereagainst the antifriction plates thrust; - a working surface of each die at its cross-section consists of a central working zone and two side zones (53, 54) with the maximum width of the die working surface (b max) and the antifriction plate sliding surface length being in a ratio of b max /l ≤ 1.5. - top- and bottom die holders (1, 2) for holding a top and a bottom die having inclined planes for operationally interconnecting thereto side die holders (3, 4) having inclined planes which correspond to the respective inclined planes of the top- and bottom die holders (1, 2) and being arranged so that they are movable relative to top- and bottom die holders (1, 2) while being interconnected thereto by means of the apart-guiding ways; - antifriction plates arranged on the inclined planes of the die holders and four dies with working surfaces; wherein the side die holders (3, 4) have a shape approximating to that of a truncated pyramid; - in a first alternative, apart-guiding ways are arranged on the side surfaces of die holders, which amounts at least four apart-guiding ways; - in a second alternative, apart-guiding ways are arranged on the inclined planes of the die holders in the longitudinal symmetry plane of the device, which amounts at least two apart-guiding ways; - in a third alternative, apart-guiding ways are arranged on the side surfaces and on the inclined planes of the die holders in the longitudinal symmetry plane of the device, which amounts at least six apart-guiding ways; - internal planes of said apart-guiding ways being formed to enclose the planes of adjacent die holders or elements rigidly secured on said die holders thus creating a clutch-type connection; characterized in that - the centre of mass of the "side die holder (3, 4) - side die " system is located within the limits of a side die holder (3, 4) longitudinal section; - in the bottom part of inclined plane of each side die holder (3, 4) respective ledges (48, 49) are provided, whereagainst the antifriction plates thrust; - a working surface of each die at its cross-section consists of a central working zone and two side zones (53, 54) with the maximum width of the die working surface (b max) and the antifriction plate sliding surface length being in a ratio of b max /l ≤ 1.5.
