Four-Roller Rolling Machine

The machine adopts the four-roller structure with the upper roller as the main
drive,Both upward and downward movement Through hydraulic motors powered.The
lower roller makes vertial movements and imposes a force on the piston through
the hydraulic oil in the hydraulic cylinder so as to clamp the plate tight.Side
rollers are arranged on the two sides of the lides of the lower roller,and make
inclining movement along the guide rail,and provide drive through the screw,the
nut,the worm and the lead screw.The advantage of the machine is that the
preliminary bending and rolling of the top ends of the plates can be conducted
on the same machine.
