FIELD: machine building.
SUBSTANCE: clamping cartridge with pressure rollers includes a cartridge base, a cartridge and a drive mechanism a, a drive mechanism b, a first clamping mechanism, a second clamping mechanism, a third clamping mechanism and a fourth clamping mechanism located on the cartridge. Cartridge is installed in base of cartridge by means of antifriction bearing and is connected with step motor by means of gear transmission. At that, drive mechanism a is intended for actuation of the first clamping mechanism and the second clamping mechanism, and drive mechanism b is intended for actuation of the third clamping mechanism and the fourth clamping mechanism.
EFFECT: achieving lateral clamping of steel pipes with provision of accurate centring and application for rectangular pipes of different sizes; elimination of damage and oscillations of the processed part at clamping due to accurate control of clamping force by the step motor.
