2.2 Product specification  

3. Full - Automatic U shape  roll forming machine

Hydraulic following feeding---> Leveling---> Punching ---> forming ---> Hydraulic cutting---> output    

Machine main parts specification 

The decoiler foundation is welded by steel plate, automatic parts is including the taper adjusted block, hydraulic cylinder, and cylinder joint lever, etc.

Operating principle: Via hydraulic motor drive to hang main shaft, main shaft extension via the hydraulic cylinder to drive the joint lever, via the taper adjustment block to realize extension the coil.

Feeding and stop is via photoeletric controller

The feeding car is via bottom two cylinders shrink to realize the car lifting.

Feeding car power is driven by gearbox and motor in the bottom of the car. 

2，leveling and pinching

The leveling roller is four rollers for feeding, four rollers for guiding, five rollers for leveling. It is including leveling rollers, mobile slider, rack leveling gap adjustment device, etc. the roller is arrangement with 2 top rollers and 3 bottom rollers. The bottom rollers are installed on the machine foundation via roller base, the top rollers are installed on the moving beam via the roller base.

The coil is via decoiler to pass the left and right roller guide to the pinch roller, which transfers to 5 roller leveling device to level. Leveling device power is 5.5KW, 2 pinch rollers are with clutch, after the steel is pre-leveling, via left and right guide roller and top and bottom pinch rollers to transfer the steel to the forming machine, the clutch break away, the feeding power is closed.

6，PLC system

The whole line is used PLC to control, using man-machine interaction mode to input and modify the parameter, Operating cabinet is located in the output in order to operate the machine, easy to operate and match the jerk button. Electronic cabinet is close to the motor in order to reduce the energy consumption.

Setting : “Automatic , manual “ picture, setting “monitor” picture in order to know the production situation. Setting the parameter display function, input and editing function, accumulative function and fault display.

Safety function:

1） Under the mode of manual or commissioning, operating panelswitch can order the each component to operate.

2） Setting short range back off function

3） For using the electrical appliance in steady working condition, the electronic cabinet installs the A/C. 

7，Production precision
