EZHONG CNC 4 roll bending machine has the function of pre-bending the end of the sheet. This kind of heavy rolling machine has four work rolls. The work roll is one of the most important components of the 4 roller plate bending machine. The quality and performance of the work roll directly affect the service life and rolling accuracy of the 4 roller plate rolling machine. Therefore, the selection and processing of the work roll have always been the most important part of the company.

Material: 42CrMo alloy steel, quenching and tempering treatment makes the work roll strength reach HB241-260, comprehensive mechanical properties, high strength, strong wear resistance, suitable for high-load work, long service life. The lifting displacement is controlled by sensors and PLC, automatically leveled, and displayed on the screen.

4 roller plate rolling machine for sale at ezhong group with jaw weights of 20x2000mm, 60x4200mm, and 80x3000mm are widely welcomed by customers. With a high technical level, complete functions, high precision, and convenient operation, a 4 roll plate bending machine is an ideal model for rolling round, arc, cone, and special-shaped workpieces.

4 Rolls Plate Bending Machine Working Principle

1

Very durable spherical roller bearings are used on each roller of 4 roll plate bending machines.

The roll plate bending machine adopts the brand's spherical roller bearing on each roller so that it can well offset the pressure caused by the deviation of the shaft during the rotation of the roller.

Since each roller can move freely and flexibly, the risk of scratches and cracks on the roller is avoided.

2

The adjustable center bearing's internal design allows it to withstand the deflection and tilt of the roller rod. Foldable activity prevents the reverse force from damaging the 4 roll plate bending machine design when it is fixing the external force.

Advantage of this bearing: the used 4 roll plate bending machine for sale can move smoothly and safely along the tilt table of the roller shaft and return to its original position finally no matter where the shaft has deviated. The relative requirements of the conical coil are much more demanding because it requires the 4 roll plate roller shaft to be able to tilt, the load on the roller shaft is not well balanced.

3

The sheet metal roll forming machine puts a lot of pressure on the bearing, and use of an adjustable center bearing can make this load enter the "axial" mode, which effectively control the influence of folding and can rotate on its own smoothly and safely.

Solution: Use two adjustable bearings on each roller shaft, so that our clients can enjoy the benefits of "permanent lubrication technology". And the bearings do not need to be frequently lubricated during the entire working life of the 4 roll plate roller.
