Product Details

Up roller is the main driven , the motor works with planetary reducer to drive, to ensure the exact accuracy when make rolling and pre-bending process. In addition, there also equipped super electrical hydraulic push rod brake on the high-speed bearing of the speed reduction gear.

All above these things is to ensure the whole body has enough strength, the main joints connected reasonable , it’s easy to install and repair.

The hydraulic system consists of gear pump, valve group, fluid connectors, hydraulic auxiliary parts, etc. Besides, we choose superposition valve series for the hydraulic valve. Simple pipe arrangement, make it convenient to maintenance and debugging.

The hydraulic system is composed of three kinds of circuit, there are over pressure protection and pressure regulating circuit, synchronization loop, and speed loop components. The pressure regulating circuit system works through the main relief valve pressure.The system working pressure is 19.5Mpa.

Synchronous circuit through the shunt throttle valve on roller rise and fall of coarse step shunt synchronization, throttle exam up and down regulating displacement sensor detection, and the upper roller synchronous positioning accuracy is 0.20mm.

The speed loop control overturning side machine overturned, reset, and adjust circuit with throttle speed through the throttle valve.

Overflow valves are adopt to protect limited rise and fall of upper roller.

The main valve groups in the hydraulic system use YUKEN products. The valve group is a casting flow channel which has large flow rate, small resistance, small pressure loss and small heat.So that the performance of the machine is more reliable. The hydraulic system has suction and return oil filter.

The hydraulic pipe joints are all equipped with the new technology, which is a quick fitting joint for metallurgical mines. The joint has a reliable radial seal to ensure that the hydraulic system does not leak oil during the operation.
