W12 4-roll plate bending machine adopts with mechanically-driven up-roll, and hydraulically-driven low-roll and side-roll, is electrically controlled. The machine can finish pre-changing of two ends of plates, rolling of cylindrical or arc parts, levelling and pre-bending of metal plates at one time.
W12NC-20x3000 4 Roll Plate Roller widely used in petroleum, chemical industry, cement, boiler, shipbuilding, aviation, water conservancy, power transmission towers and other machinery and equipment. Its working principle is rotating bending deformation. For the upper roller can be moved no matter up and down, but also horizontally, so no need additional press or equipment, can realize pre-bending, bending, as well as correction of the workpiece.
The whole structure of Hydraulic Plate rolling machine :
1.Totally European design,streamlined looking,frames of our machines are fabricated, welded steel (ST-52). Roll shafts, materials and bearings used in production are European quality. Also the torque limit of the machines is very high. NC playback and NC graphic control systems are available as optional accessory.
It is curved and calibration equipment, which specialized in sheet metal bending work.
It can roll a variety of specifications of cylindrical, and curved work pieces.
The sheet metal can be shaped and flattened on the four roller bending machine.
Appropriately adjusting the relative position between the side roller and the top roller, by repeatedly roll bending, cylinder can be shaped, the minimum diameter of the cylinder is up to the diameter of top roller.
Four-roller bending machine are with a wide range of needs and functions in the petroleum, chemical, shipbuilding and machinery manufacturing industry.
