Roll Bending Machine

W11 roll bending machine 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 bending, as well as correction of the workpiece.

And this 3 roller sheet bending machine is designed to roll flat plate into round or canister shape, which in turn can be used for the manufacture of ventilation, or sewage pipes also chimneys for the exhausting of air. This type of pipe is especially suited for buildings that have environmental regulations

The working area required for the bending machine is not large, while its operation is simple. Adjustment for different diameter materials is an easy task to perform. The machine is constructed with welded steel plate to give a rigid working platform in which is housed the drive system for the rollers.

Designed to function by a symmetrical 3-roller unit, which is driven by two motors. The rolling speed is appropriate to the diameter of the plate to be rolled. Transformation of the flat plate into the round is performed without the surface or the tensile quality being affected. The operation and adjustment of the machine is very easy.

Our 3 roll plate bending machines offers many advantages. They are reliable and tested bending machines, with three rollers pinching that guarantee a precise and constant drag of the material.

Side wheel for angle steel/steel pipe bending are available (supplied on customers request).

 

Basic Information

Descriptions

Driving System

The machine has three round rollers with the downward two rollers being the main rollers. The lower roller is chain driven. The transportation of flat steel plate through the rolling system will produce a cylindrical shape.

Operation and Adjustment.

Place flat steel plate between the upper and lower rollers. Then start the up and down motor 2, the upper roller presses down onto the work piece. Start the main motor 1. The lower roller will start to rotate driving the upper roller.

In steps increase the pressure of the upper roller. The right roller rotates, while the opposite roller turns to give a cylindrical work piece or can shape.

The work piece is on the upper roller, unload the work piece loosen the securing wheel, open the upper cover, loosen the stud, then press the ball bush of the upper roller. Start the up and down motor 2 the upper roller will rise. You can now remove the work piece.

When you find the upper and lower rollers are not parallel you need to adjust the rollers. First loosen the left connecting rod four screws, then rotate wheel by hand in order to adjust the upper roller right end by 0.1mm with every rotation of the drive belt wheel.
