Description:

1. The mechanical roll bender for sale integral structure, the foundation is simple, the movement is convenient。The bending machine adopts an integral chassis, without anchor bolts, the basis is simple, convenient mobile workplace.

2. The shape of the curved roll formed steel workpiece is abundant. This machine can rolling type O, U, R, auxiliary cones device. Type O bending: the rear bending mode.Type U bending: the forward bending mode. Multi segment R bending: a combination approach

3. The high precision of the end of the pre bending, free to set the straight edge length. Direct pressing and pre bending of the upper roller can finish high precision end pre bending.

4. The technological parameters of the rolling products are NC, the operation is simple, and the efficiency is greatly improved.

5. The roller is in a drum shape, and the lower part of the lower roller is provided with a supporting roller to adjust, continuous bending, and the ideal product can be rolled out from a wide range of thin plate and thick plate.

6. The safety of the operation: On the two bottom rollers fixed, roll up and down, move around, don't over work roll movement of workpiece, the operators safety.

3 roller bending machine

Structure and main parts:

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 42CrMo; 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 is 380V50HZ, adopted PLC control system code with longevity easily operate. Whole bending process can read from the indicator setting on the control box.
