Precision Plate Bending Machine with 4 Rollers for Heavy Fabrication

Product Description

W12NC 4-roller rolling machine

Introduce:
The machine adopts the four-roller structure with the upper roller as the main drive.
The equipment has the function of pre-bending the end of the plate. The metal sheet can be loaded at one time, and the plate end pre-bending and the roll forming of the workpiece can be completed without turning.
The upper working roller of this machine is the main driving roller. The lower roller and both sides of the roller adopt hydraulic transmission. The lifting displacement is controlled by the computer, automatic leveling, screen display, and the tilting and resetting of the turning bearing body to adopt hydraulic transmission. The tail of the upper roller Equipped with a balance mechanism to facilitate the unloading of the rolled workpiece and cylinder. Equipped with a mobile independent operating table, which can be moved and operated at any time, and the machine is equipped with a safety interlock device. The machine has a high technical level, complete functions, high precision, and easy operation. It is the most ideal model for rolling round, arc, and conical workpieces in industries such as energy, transportation, petroleum, chemical industry, boilers, shipbuilding, hydropower, and metal structures.
