Main motor power
This equipment composed of main machine part, hydraulic system, electricity control system.
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.
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 20Mpa. Max pressure of upper roll multiplies 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 45# steel; heat treatment is HB220-280.
2) Down roll and level motion device
The material of down roll is 45# steel; heat treatment is HB220-280. It composed of down roll, down roll bearing pedestal, down roll input gear, down roll, glide bearing. Down bearing adopt SF-2 oil glide bearing.
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.
3) Support device
Composed of sloping block device, support device, support rolls bearing pedestal, support lifting device, support rolls can adjust up and down. The adjustment depends on plate speciation. The material of support is 45# heat treat HB217-240, it made up in helix sharp to protect the surface.
4) Main drive device
It composed of motor, hard gear speed reducer, output gear, and main motor can turning in two directions and provide bending pitch of strand.
5) Turning device
Composed of ram, bearing, turning cylinder
6) Balance device
Composed of balance compact, screw
7) Lubricate device composed of lubricate pipe, and lubricate pipe Attachment, adopted GB7323-1994 NO 2 lithium grease.
2. Hydraulic system
Composed of Y series motor, gear pump, valves, oil tank, pipe and so on.
Max pressure is 20Mpa, testing pressure is 24Mpa, and pressure adjusted by overflow valve, system working pressure 0-19Mpa, and normal pressure is 15Mpa.
The valve adopted from Taiwan.
3. Electricity system
Composed of electrical box, operation table, and manual button. The power can be required by customers, adopted PLC control system code with longevity easily operate. Whole bending process can read from the indicator setting on the control box
1. Upper roll can move in vertical and level include pre-bending function
2. Adopted many points to lubricate.
3. Mechnical, hydraulic, electricity all system set over loading protect device.
4. Fitted quality CNC system fault check itself automatically, error give an alarm, mistake protection and so on
5. Adopt hand switch button box easily operate.
6. Simple foundation equipment, it can move to operate.
