This machine belongs to the mechanical transmission three roll plate rolling machine, which is used to roll steel plates into cylindrical, curved, and conical shapes.The upper roller presses down and is driven by an attached motor through a reducer to transmit power to the worm gear, screw and nut pair, causing the plate to bend and deform. The rolling transmission is driven by the main motor through the main reducer and open gear to rotate the lower roller, and becomes the main power source during plate rolling.
