W12NC-50x2500 4 Roller Plate Rolling Machine


W12NC-50x2500 4 roller plate rolling machine with international advanced technology, controlled by PLC programmable numerically, is hydraulic equipment in advanced and reliable technology architecture, with sufficient rigidity, and other key parts of the work roll for reasonable selection, precision manufacturing, high-performance, precision long retention period for long-term continuous processing, stable and reliable operation control, simple operation, is a high-precision, high efficiency in rolled sheet metal with unique advanced equipment.

4 Roller Plate Rolling Machine
W12NC-50x2500 4 roller plate rolling machine

It's a heavy duty CNC rolling machine which can come true automatic bending, can finish material’s ending pre-bending and rolling with one times feeding of metal material.The machine is suitable for bending work of sheet metal. It can roll round, arc and tapered workpiece in a certain range, and has prebending function at the end of the board. The remaining straight side is small and the working efficiency is high, and the metal plate can be roughly leveled on the machine.

W12NC-50x2500 4 roller plate rolling machine which has many advantages:small residual straight edge.It's the ideal equipment of rolling round,arc,cone workpiece, its the nesy equipment for bending multi section curved, square, round, conical and other special shape working piece.

Compared with 3 roller bending machine:

Full CNC control when rolling coiling block;

High bending precision;

Improve work efficiency, save prdoction time and labor--save cost;

Can do cones with smaller diameter.

The machine belongs to the hydraulic type four-roll bending machine for steel plate at room temperature to roll into a cylinder shape.

The top roll can be fixed, and bottom roll and both side rolls can be moved up and down both sides of the roll.

Top and bottom roll are main driven rolls through its rotation torque to provide a sheet roll, and both sides of the roll are passive roll.

For pre-bending, the top and bottom roll are holding the plate, and side roll lift to deform the panels to achieve.

Work and lift function are hydraulically driven.

It is easy roll-circular cylindrical and the tapered barrel shape capacity.

To facilitate the cone rolling, this device can roll and tilt adjustment for bottom roll and both side roll.
