Overview :
The process of a rolling machine rolling metal shee ts involves the continuous bending of the sheets at three points. Depending on the rolling temperature, it can be classified into cold rolling, hot rolling, and warm rolling. This machine is primarily used to bend metal sheets of a certain thickness into cylindrical, arc, rectangular, or other curved shapes. It is an essential piece of equipment in industries such as metallurgy, construction materials, petroleum, chemicals, hydropower, bridges, war, coal, mining, shipbuilding, boilers, aviation, and the manufacturing of electrical transmission and transformation equipment.The upper roller serves as the main driving roller on this machine, which features pre-bending and CNC rolling functions for the end portions of the metal sheets. It can feed the metal sheets once, completing both pre-bending at the sheet ends and the rolling of the workpiece without the need to turn around. The hydraulic motor on the upper roller is equipped with an instant brake, allowing the rollers to accurately stop rotating during the bending and rolling process. The lifting and lowering of the lower roller and side rollers are all hydraulically driven, with displacement controlled by the computer. The displacement of the lower roller and side rollers can be directly observed through CRT display by using encoders for detection. The machine offers advantages such as simple operation, convenience, and high efficiency.
The machine can automatically level, with screen display and synchronous accuracy of ±0.2mm. The tilting and resetting of the flipping bearing housing are hydraulically driven, and the tail of the upper roller is equipped with a balancing mechanism for easy removal of the rolled workpiece and cylinder. It includes a movable independent operating platform for flexible movement. The machine is equipped with safety interlock devices, ensuring good safety.

Accuracy :≤±0.2mm
When synchronously controlling the position of the working rollers, the synchronization accuracy is ±0.2mm.
CNC Upper Roller Universal Three-Roll Rolling Machine
(Upper Roll Adjustable in Vertical and Horizontal Directions)
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).

CNC Horizontal Lowering Three-Roll rolling Machine
(Upper roll adjustable vertically, lower roll center distance adjustable horizontally.)
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.
