4, inspection

Composed of electrical box, operation table , manual button . the power is 380V50HZ adopted PLC control system code with longevity easily operate. Whole bending process can read from the indicator setting on the control box.

3-3 electricity system

Max pressure is 20 Mpa , testing pressure is 24 Mpa , pressure adjusted by overflow valve, system working pressure 0-19 MPa , normal pressure is 15Mpa . the valves adopted from Taiwan.

Composed of Y series motor, gear pump , valves , oil tank, pipe and so on.

3-2 hydraulic system

7) lubricate device composed of lubricate pipe and lubricate pipe attachment, adopted GB7323-1994 NO 2 lithium grease.

Composed of balance compact, screw

6) balance device

Composed of ram, bearing, tuning cylinder

5) tuning device

It composed of motor, hard gear speed reducer, output gear, main motor can tuning in two direction and provide bending pitch of strand.

4) main drive device

Composed of sloping block device, support device, support rolls bearing pedestal, support lifting device, support rolls can adjust up and down. The adjustment depend on plate speciation. The material of support is 45# heat treat HB 217-240, it made up in helix sharp to protect the surface.

3) support device

Level motion motor supply the power, through the strap drive to CWU worm wheel and pole speed reducer. Upper roll level motion drove by worm wheel and pole to finish bending in dissymmetry form.

The material of down roll is 42CrMo, heat treatment is HB220-280. it composed of down of roll, down roll bearing pedestal, down roll input gear, down roll, glide bearing. Down bearing adopt SF-2 oil glide bearing.

2) down roll and level motion device.

1) upper rolls device composed of main cylinder, upper bearing pedestal, upper rolls, double self-aligning bearing .two cylinders provide the pressure for upper roll bending , main cylinder working pressure is 20 Mpa ,max pressure of upper roll multiply 0.8 times to compensate for pre-bending. Upper roll two ends fit with double self-aligning bearing to reduce the friction and motor power. The material of upper roll is 42CrMo , heat treatment is HB220-280.

3-1 main machine part composed of top rolls , down rolls and level motion device support rolls device , tuning device , balance device, lubricate device , left and right work frame and bottom plate.

  This equipment composed of main machine part, hydraulic system , electricity control system.
