Summary:FIELD: forging press production, namely error compensation system for providing forging size of radial forging machine with pulsation type hydraulic drive of strikers. ^ SUBSTANCE: system includes boosters, pickups for measuring displacement of outlet links of main hydraulic cylinders and pistons of boosters, electrically-controlled four-way three-position throttling hydraulic distributors, electrically-controlled four-way guiding hydraulic distributors and electronic control unit. Inlets of said unit are connected with outlets of displacement pickups; outlets of unit are connected with electric inlets of four-way three-position hydraulic distributors. Actuating ducts of each hydraulic distributor are connected with inlet cavities of respective booster; pressure duct is connected with hydraulic liquid source and draining duct is connected with drainage. Each of two outlet cavities of booster is connected with power hydraulic line between working stroke cavity of main hydraulic cylinder of radial-forging machine and working chamber of respective pulsating pump and with pressure hydraulic tank through two-way two-position locking devices. ^ EFFECT: enhanced accuracy and efficiency of forging. ^ 4 cl, 1 dwg
