Описание

W12-10*3000 CNC Hydraulic Roll Bending Machine Automatic Four Roller Sheet Metal Plate Rolling for Stainless Steel

Четырехвалковый листопрокатный станок серии W12CNC

This machine is a four-roller plate rolling machine. Its operational principle involves the coordinated movement of four rollers:

Top Roller: Acts as the main drive, rotating to pull the plate through.
Lower Roller: Moves vertically to clamp the plate and generate the necessary feeding friction.
Side Rollers: Adjust up and down at an angle to the vertical axis, applying precise force to bend the plate to the desired curvature.

The significant advantage of this configuration is its ability to adjust the side rollers for both symmetric and asymmetric bending. This process minimizes the un-bent flat ends at the plate’s leading and trailing edges. Consequently, unlike three-roller machines, it eliminates the need for a separate pre-bending operation and dedicated equipment, while also providing a rough leveling function.

Due to these efficiencies, this machine is widely used in critical sectors including petroleum, chemical, boiler and pressure vessel manufacturing, shipbuilding, hydroelectric power, metal structure, and machinery industries.

Standard Plate Rolling Procedure
1. Position and Clamp: Align the leading edge of the plate with the front main roller. Raise the lower roller to clamp the plate securely.
2. Set for Pre-bending: Retract the plate so its leading edge is near the nip point of the upper and lower rolls. Lower the front side roller and raise the rear side roller to their pre-bending positions.
3. Pre-bend the Edge: Drive the main rolls to rotate the plate. Pre-bend the leading edge to the required curvature.
4. Set for Rolling: Lower the rear side roller and raise the front side roller to their starting positions for the full rolling cycle.
5. Roll the Plate: Drive the main rolls to continuously roll the plate into a cylinder.
6. Finish the Roll: Once the trailing edge of the plate approaches the nip point, stop rotation to complete the rolling process.
