Plate Bending Rolls CNC Roll Bending Machine Sheet Metal Rolling Equipment

W11S series plate rolling machine is a new type and produced by advanced foreign technology, the machine can pre-bend and roll plate at one time, with high accuracy of rolling plate, no auxiliary equipment, investment less. Widely used in petroleum, chemical, boiler, shipbuilding, hydropower, metal structure and machinery manufacturing industries.

Economical and practical fully hydraulic 3-roll bending machine with pre-bending
Rolls length up to 6.000mm, plate thickness up to 150 mm, we can design and manufacture special rolling machine according to customer request.

User's manual in English

1. The wide based frame construction is designed to bring increased stability to the whole structure

2. hydraulic systems and components studied to reduce the pressures of work and have a longer life

3. Rolls driving by motor, speed-reducer

4. Hardened and polished rolls and conical device

5. Separate control desk on wheels

6. 3-roll plate bending machines covers plate thicknesses from 6mm to 150mm and widths from 1,000mm to 6,000 mm

7. The top rolls move up and down by hydraulic

8. The 3 rolls bending machine utilizes 2 driven rolls to ensure the rolling torque power transfer

9. All rolls journalled in spherical roller bearings (Long life lubricated)

10. Roll camber is required to counter act roll deflection



 

Step 1: Feeding the board and matching materials;

Step 2: The upper roller moves horizontally to the -X position and descends to the Y1 position;The lower roll is reversed to bring the steel plate to the forming position.

Step 3: The lower roller rotates forward while the upper roller presses down;

Step 4: the upper roller is pressed down to the Y2 position to stop, and the lower roller continuously rotates forward;

Step 5: Stop at the end of the board, stop by pressing Y3 under the upper roller, and directly press and pre-bend the end of the board;

Step 6: Lift the upper roller Y2-α, move horizontally + X position, press the same position Y2, the lower roller rotates forward;

Step 7: Stop at the end of the board, stop at position Y3 when the upper roller is pressed, and directly press and pre-bend the end of the board;

Step 8: Move the upper roller to X = 0, press down to the Y4 position, the lower roller is forward and reverse, and compensate for bending.

1. The drum-shaped upper roller and supporting roller of bottom rollers are adjusted together to achieve high-precision product straightness

The drum-shaped upper roller is adopted, and drum-shaped preset amount is generally at 70% of the roller load. smaller diameter bottom roller, the lower part of the lower roller is supported by an adjustable idler roller. According to the load of the rolled product, the idler roller at the lower part of the lower roller is adjusted, which greatly improves the straightness of the product.


2. Rear bending and rolling, high-precision product roundness

The plate rolling machine adopts backward bending (the feeding direction of the plate is opposite to the moving direction of the upper roll), the upper roll is pressed down while the lower roll is rotating, continuous bending, the end of the plate is pre-bent and directly pressed and pre-bent , to avoid the generation of front curved rear corners, and can control the length and shape of the remaining straight sides.
