China supplier bending and rolling machine(CNC Upper Roller Universal Three-Roll Rolling Machine):
Product Features :
1.This machine is a hydraulic three-roll rolling machine used to roll steel plates into cylindrical, conical, and corrected circular shapes.
2.The upper roller can move both vertically and horizontally.
3.During pre-rolling, the upper roller achieves asymmetrical positioning relative to the lower roller through horizontal movement.
4.For conical rolling, the upper roll tilts at both ends to complete the rolling of the cone.
5.In circular correction, the upper roll is positioned in the center to press and roll the stress zone of the cylinder, eliminating welding stress and improving the roundness of the cylinder.
6.During rolling, the lower rolls are driven by an electric motor and gearbox to provide torque for the rolling of the cylinder.
7.Key technical parameters: (taking a plate with a yield strength of 245Mpa, thickness of 30/100/150mm, and width of 3000mm as an example).

China supplier bending and rolling machine(CNC Horizontal Lowering Three-Roll rolling Machine)
Main features :
1.This machine belongs to the hydraulic type three-roll rolling machine, used for rolling steel plates into cylindrical, arc-shaped, conical, and corrected circular shapes.
2.The upper roll can move vertically.
3.Pre-rolling is achieved through the horizontal movement of the lower roll, which positions it asymmetrically relative to the upper roll.
4.During rolling and circular correction, the working rolls are driven to provide rolling torque for the rolled plate.
5.The elevation of the lower roll remains unchanged, facilitating feeding and operation.
