Precision of the superior products
Unique crooked craft , the high-accuracy tip is curved in advance, the crooked angle after not having in succession, the crooked course is digital control.
Man-machine dialogue controls the high-efficient intelligence of interfaces to operate
Peculiar crooked craft software, the interactive window, the automatic compensation of the crooked course, operate singly, high-efficient and safe and convenient!

Abundant crooked form
Have rolls of form to make O type, U type, many sections of R ,etc. different forms.

Choice of many modelsAccording to the use or users' enquiry, count and show the model economily, TC numerical control model chooses.

3.The Main Structure:

This equipment should be composed of main structure, hydraulic system , electricity control system and cone device.

3-1. The main structure

The main structure is composed of upper roller , down rollers and level motion device support rolls device , tuning device , balance device, lubricate device , left and right work frame and bottom plate.

1) The upper roller

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. HRC 45-55

2) Down roll and level motion device.

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.

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 depend on plate speciation. The material of support is 45# , heat treatment is HB220-280, it made up in helix sharp to protect the surface.

4) Main drive device

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

5) Overturn device

Composed of ram, bearing, tuning cylinder

6) Balance device

Composed of balance compact, screw

3-3. Hydraulic system

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

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.

3-4. Electricity system

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.

3-5. Digital display system

This machine adopts two sets of digital instrument and displacement sensor formed a reliable digital display and control system.
