Product Description

China manufacturer 4 roll bending 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 manufacturer 4 roll bending 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.

6.Technical parameters :(Taking a plate with a yield strength of 245 MPa, plate thicknesses of 20/60/100mm, and a plate width of 3000mm as an example.)

China manufacturer 4 roll bending machine (Fully Hydraulic CNC Four-Roll Plate Rolling Machine)

Product Features :
1.This machine is a fully hydraulic CNC dual-drive four-roll plate rolling machine, capable of rolling metal sheets into cylindrical, arc, and conical workpieces. It can simultaneously satisfy processes such as pre-rolling , rolling, circular correction, and conical rolling. The machine can complete the pre-rolling  and rolling of the ends of the sheet metal without the need for auxiliary devices, and it leaves minimal straight edges.

2.This equipment is designed reasonably, with a simple and compact structure, flexible and convenient operation, high reliability, long service life, low energy consumption, and high processing/control accuracy.

3.This equipment features fully hydraulic dual-drive upper and lower rolls with digital control.

4.This equipment has conical rolling functionality and can roll conical cylindrical bodies.

5.This equipment has conical rolling functionality and can roll conical cylindrical bodies.
