Two master cylinders provide the pressure required to roll the sheet, and the working pressure of the master cylinder is 19.5MPa.
Double row aligning bearing adopts low speed and heavy duty aligning roller bearing.
The upper roll is shaped like a drum, which is used to compensate for the deformation deflection of the upper roll.
The upper roll is made of 42CrMo, tempered after rough processing, HB260-300; After finishing, medium frequency quenching HRC45-50.

Lower roller and horizontal moving device

The lower roller device is composed of a lower roller, lower roller bearing seat, lower roller sliding bearing, lower roller input gear, etc.
The lower roll device provides positive and negative torque for the coil sheet. Through the main drive output gear and lower roller input gear, transmission torque.
The lower roller is made of 45# steel, tempered and processed, and the surface of the roller body is mechanically strengthened.
The lower roller sliding bearing is made of SF-1 self-lubricating composite material.
The horizontal moving device is powered by the horizontal moving motor and drives the frame and upper roll components to move horizontally through the worm transmission mechanism and the spiral transmission mechanism to realize the pre-bending of the workpiece and the asymmetric winding.

Lower roller and horizontal moving device

The idler device is composed of an idler combination, oblique wedge mechanism, and spiral mechanism.
The adjusting screw drives the two groups of inclined wedges close to or separate, thereby raising or lowering the idler combination.
The roller is made of 45 steel, tempered treatment, and hardness is lower than the lower roller.

Main drive system

The main drive system is composed of the main motor, reducer, output gear, etc.
The system can rotate positively and negatively to provide working power, and transfer torque to the lower roll through the main reducer, output gear, and lower roll gear, so that the lower roll rotates, and relies on friction to drive the plate feed to complete the winding work.

Tipping device

The tipping device is composed of a pin shaft, a ram, a tipping hydraulic cylinder, a support, etc.
The tipping hydraulic cylinder drives the tipping frame to tip over or reset. When the frame is tipped over, it is easy to remove the product along the tip end.

◆ Balancing device： The balancing device consists of two pull rods and a balancing beam.
After the tipping side frame is overturned, the balancing device presses the tail of the upper roll to maintain the balance of the upper roll.

◆ Rack： Fixed and overturned frame for welding parts, after welding vibration aging to remove stress treatment. The frame is used to mount the hydraulic cylinder and move the upper roll components horizontally.

◆ Base plate： The chassis is a box welded structure, an annealing treatment. Used to install components.

Electrical control system

The electrical control system consists of an electrical control cabinet, an operation table, and a hand-held button box.
Main technical indicators of the system:
The system operating voltage is 380V/50Hz.
The ambient temperature is -5 degrees to 45 degrees.
The control circuit adopts a PLC programmable controller system, fewer relays, reliable operation, and long life.
The control cabinet is equipped with all the buttons and indicators to complete the entire winding process, which can control the working state and operation of the whole machine. The handheld button box provides convenience for the control of key operations in the flow operation.

Numerical control system

The CNC system has the functions of real-time monitoring, in-place control, and short electrical memory in the rolling process.
Real-time monitoring: The touch screen displays the displacement Y up and down the main cylinder of the upper roll and the horizontal movement X of the upper roll at any time.
In-place control function: the number and function keys on the touch screen can set the process parameters, which can realize the in-place control of the upper roll up and down and the horizontal movement.

Wireless remote controller

Control the plate rolling machine by handheld remote control, easy to operate.

Tipping device

The tipping device is composed of a pin, a ram, a tipping hydraulic cylinder, a support, etc. The tipping hydraulic cylinder drives the tipping frame to tip over or reset. When the tipping frame tips over, it is convenient to take out the product along the tipping end.
