Hydraulic straightening machine is suitable for straightening,

processing kinds of steel pipes, also for calibration. It is equipped with special straightening workbench, lifting movable and rotary roller, U shape pressing head, external conveyor roller.

This machine has independent power system and electrical system, adopt button centralized

control mode, with inching and semi-automatic function. In auto mode, can realize fast down, slow down, pressure maintaining , pressure relief and return stroke automatic cycle In inching mode, it can realize the action at each press a button, loosen the button to stop action.

Oil system uses cartridge valve system, equipped with large flow rate high pressure variable axial plunger pump, low noisy, small power loss and with slow system temp rise. Equipped with high-quality Rexroth electromagnetic directional valve, high accordingly, reliable and compact structure, no leakage. Equipped with fine and coarse two-stage filter, strictly control the oil clean degree, provide reliable working environment for the stable operation of the system. Pipeline is connected by high pressure hose tube, fully eliminate vibration and slow down the leakage possibility.

Electrical system adopts PLC semi-automatic control system, main circuit voltage according to user requirements. Electrical elements uses Siemens or Schneider product. Control voltage DC24V. Equipped with induction position switch, with pressure maintaining, pressure relief and time delay function, the time can be adjusted.
