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.
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
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
(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.
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
