■ This machine is a special equipment to roll the plate into curve, cylinder, conical in the principle of three point circle. The action as below.

■ Top roller move by vertical. Power: hydraulic oil tank. Role: put the pressure on the plate to make the plate bending deformation.

■ Top roller move by horizontal. Power: electromotor. Role: adjust the horizontal distance between the top and bottom roller to make the top and bottom roller position in asymmetrical to pre-bend the sheet edge and decline the length of the flat zone.

■ Bottom roller rotate, Power: electromotor. Role: supply the torque for bending plate.

■ Opening device drop down and reset. Power: hydraulic oil tank. Role: take out the finished workpiece.
