4 Rolls Plate Bending Machine

EZHONGis located in the ancient city of Wudu - Ezhou City, Hubei Province. It is one of the heavy forging and shaping equipment enterprises designated by the former First Machinery Department to produce plate bending rolling machines and plate straightening machines. It is a manufacturing company with an independent legal personality established after reform, reorganization and restructuring.

EZHONG CNC 4 roll plate bending machinehas the function of pre-bending the end of the sheet. The 4 roll plate rollermachine has four work rolls. The work roll is one of the most important components of the bending machine. The quality and performance of the work roll directly affect the service life and rolling accuracy of the bending 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 salewith jaw weights of 20x2000mm, 60x4200mm, and 80x3000mm are widely welcomed by customers. With a high technical level, complete functions, high precision, and convenient operation, it is an ideal model for rolling round, arc, cone, and special-shaped workpieces.

Working Principle Of 4 Rolls Plate Bending Machine

1

Very durable spherical roller bearings are used on each roller of four roller bending machines.

The product 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 roller when it is fixing the external force.

Advantage of this bearing: It 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 roller shaft to be able to tilt, the load on the roller shaft is not well balanced.

3

It 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.

4

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 product.

Advantage of EZHONG 4 Rolls Plate Bending Machine

The Control system adopts the PLC programmable controller of an internationally renowned company. The system has parameter settings, data editing, good alarms, power-off memory, man-machine interface, status display, real-time calculation, file storage, debugging mode, manual mode, program control mode, file editing, fault self-diagnosis, the intelligent judgment of operating errors, and other protection functions; Also has advantages of strong anti-interference ability, long working life, earthquake resistance, and stable operation, etc.

The hydraulic system ensures the cleanliness of the system with oil suction and return oil filters. An air filter ensures the normal breathing of the fuel tank and the evaporation of water. The system has dual safety protection devices which ensure the machine's safe use. Also equipped with a centralized refueling device.

The tipping frame is equipped with a tipping cylinder, the tipping head can be tipped and upright which is convenient for the workpiece to pick up. The turning and resetting of the turning bearing body are equipped with an interlocking device. The movement can be resumed after the bearing body is reset, which plays a role in safety protection.

The 4 roll plate bending machine designadopts an integral base, which is strong in rigidity, easy to hoist and install. The frame and base are welded and processed with annealing aging treatment which eliminate internal stress and improve the bending machine precision. The whole machine structure is composed of building blocks, which is beautiful in shape and more convenient for maintenance.
