200mm Hydraulic Shearing Bending Machine , 3000mm 3 Roller Sheet Bending Machine

Pedestal and rack for equipment, welded structure, in strict accordance with process annealing to eliminate internal stress, has enough strength and rigidity to ensure work at full load under normal working status.
Upper roller for drive roll, by hydraulic motors drive hydraulic station, on the realization of work rolls drive. Machine overall assurance of sufficient strength and stiffness, mechanical parts are mainly key and pin connection for easy installation and maintenance.

2,Hydraulic system
The hydraulic system of the equipment to complete the following functions: actuating cylinder so that the lower roller for uplift; drive rollers on either side tilt movement; controlling the dumping of oil tanks in the movement.
By electro-hydraulic directional control valves may be under the control of the movement and on the sides of the roll roll tilt movement through hydraulic control valve, roller stay in any position.
Dump cylinder circuit equipped with a one-way valve, the actuator speed can be adjust.
Hydraulic system design is reasonable, reliable, and equipped with high-precision oil and oil filters, to ensure cleanliness of the oil. Pipe arrangement and tidy and easy to operate, flexible and ensure that the whole system no leakage phenomenon.
