Hydraulic 4 roll plate roller

Description

1. 4-roller type for bending the plate into a cylinder or arc or cone shape product

2. One time to finish the process as pre-bending and rolling.

3. Top roller as the drive roller driven by the hydraulic motor

4 Roll Plate Bending Machine Working Process

4. Bottom roller works up and down to clamp the material by hydraulic

5. Side Roller can work separately

6. PLC NC control and overload protect

Features:

1 The standard range covers plate thicknesses from 6mm to 100 mm and widths from 1000 mm to 6000 mm.

2 Machines are suitable machines for production of cylinders, ovals and square shaped objects

3 Hydraulically driven top and bottom rollers

4 Steel rolls with optimal crown

5 Hydraulic inclination of lateral rolls for conical bending directly from control desk through selectors

6 Minimum residual flat edges

7 Separate control desk on wheels

8 Pre-bending and bending in one operating step

Advantage

1 Simple cone bending

2 Simple calibrating of apple- or pear-shaped welded tubes

3 Can be controlled by CNC numerical control

4 Minimal wear on guide ways for long-lasting machine precision

5 High strength steel rolls are very crack-resistant

Configuration

1.Description Frame

Fully welded and stress relieved before machining to have sufficient strength

2.Description of hydraulic pressure

100% Hydraulic, 4 Rolls driven,synchronised rolls

3.Description motor

Hydraulic motors / planetary gearboxes are directly mounted onto each driving roll to ensure a smooth feed through of the plate

Application

(1) Wind towers

Wind towers are slightly conical metal tubular structures obtained by rolling plates of different thicknesses. we offer 3-roll and 4-roll bending rolls ideal in the production of wind towers and foundations. The angle rolls are an excellent solution for hot bending the flanges used in wind turbines.

(2) Aerospace / aircraft

Wing edge bending machines. Bending of small radii at long part lengths, complicated asymmetric geometries, high-ductile materials with extreme back spring etc.

(3) Energy industry

Plate bending machines are being used by leading power plant manufacturers for many bending and forming processes including reactor production.

(4) Truck containers, Road/railway tankers
