High performance 4 rolls hydraulic plate bending machine, Model: W12-20×3000, bending thickness 20mm, pre-bending 16mm, width 3100mm, top roller 360mm, top crane, two sides supports, cone bending standard.

 

Features

1 Roll plates from 6 mm, up to 80-100 mm thick

2 Fully welded and stress relieved before machining to have sufficient strength

3 Single unit high torque hydraulic motor and planetary gear box are directly mounted onto each driving roll to ensure a 4smooth feed through of the plate

4 Easily Complete Pre-Bending, Elliptic, Polycentric & Conical Bent Shapes

5 Hydraulic parallelism of lateral and pinching rolls managed by plc and valve

6 Easy operation with mobile control panel

7 World standard electrical and hydraulic components

8 Minimum residual flat edges

 

Advantage
1 Work piece only needs to be aligned once at the start of the bending process
2 Automatic minimization of flat ends
3 Secured rolling traction throughout the process
4 High strength steel rolls are very crack-resistant
5 The plate is kept squared without slipping during the pre-bending and bending cycle

 

application

(1) Wind towers
4 rolls along with our exclusive support system is the most widely purchased by top wind tower manufacturers to produce wind tower cylinders and cones, in semi-automatic mode, compact and easy operation.
(2) Off-shore platforms
4 rolls plate bending machine is the good choice to build monopiles and tripods, in thick plate and high resistance steel.
(3) Aerospace / aircraft
We can provide machines which can be used to produce aircraft and aerospace components such as wing and fuselage sections, and components for aerospace vehicles, capsules, nacelles, etc.

 

FAQ:
1. Why Using a 4-Roll Plate Bending Machine
The plate is kept square without slipping during both pre-bending and rolling because of the constant secure clamping of the top and bottom rolls. Bending the back edge takes place after the cylinder is rolled, for a one direction, single pass operation
