High performance 4 rolls hydraulic plate bending machine, Model: W12-16×2000, bending thickness 16mm, pre-bending 13mm, width 2100mm, top roller 270mm, PLC control, cone bending standard, short flat ends, different shapes.
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
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
Fully welded and stress relieved before machining to have sufficient strength
2.Description of hydraulic pressure
100% Hydraulic, 4 Rolls driven，synchronised rolls
Hydraulic motors / planetary gearboxes are directly mounted onto each driving roll to ensure a smooth feed through of the plate
(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
It is good choice to produce truck tanks, with different thickness, material, and length, can be in manual and CNC different mode.
1. Why choose swing arm technology bending?
Our plate bending rolls use swing arm technology for the movement of the side bending rolls. Each swing arm is manufactured from a solid steel profile this ensures rigidity. This design solution offers a smooth friction free movement for each side roll, a friction less system has the advantages of; more pre bending power, a maintenance free longer life unit.
2. 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
