3-roller Hydraulic Plate rolling machine
The device is hydraulic 3-roller rolling machine, it used to bend plate into cylinder-shape, arc-shape in normal temperature. The up roller of the device can lift up and down, level left and right. Level move up roller to pre-bend the plate, let the up roller in asymmetrical location relative two bottom rollers. Up roller’s lift movement adopts hydraulic driven, and level move adopts mechanical driven.
