Product Introduction
On the slanting four-roll plate bending machine, the two side rolls move up and down in a slanting linear motion. The top roll, or both the top and bottom rolls, are driving rolls. The bottom roll and the two side rolls are hydraulically driven for lifting, and their lifting displacement is computer-controlled. The pressing control and the tilting device are NC or CNC controlled. It features pre-bending of plate ends, allowing pre-bending to be completed with a single loading of the plate without turning it around. Compared with three-roll plate bending machines, it provides higher efficiency in double-side pre-bending. The top and bottom rolls clamp the plate to prevent slipping, ensuring high roundness quality and proper material alignment, avoiding edge misalignment during rolling, and enabling one-pass forming with CNC control.
(Note: Output varies depending on the automation level of the equipment and the diameter of the workpiece being rolled. Rolling of special workpieces may affect output due to the particular nature of the rolling process.)
