Four-roller plate bending machine

Work Roll

• The upper and lower work rolls are made of high-strength roll steel (42CrMo roll steel), which is completed by forging, quenching and tempering, quenching, tempering, stress relief and precision lathe machining; 
• Strictly guarantee the high contact strength of the work roll surface , There is no indentation on the surface of the roller when rolling the steel plate, which can meet the requirements of long-term rolling of the steel plate.

Hydraulic system

• The lower and side lifts are driven by hydraulic cylinders, which can lift quickly when no-load and slow when loaded, making it more energy-saving.
• Ensure that there is no leakage point in static or dynamic work, and achieve stable dynamic operation without shock, crawl.It is required that the valve group has large flow rate, small resistance, small pressure loss and low heat generation.

PLC programmable controller + touch screen + Omron displacement sensor 

• Strong anti-interference ability,
• Long service life, shock resistance, stable operation;
• Sensor displacement resolution is 0.055mm ;Display accuracy is 0.1mm.

Screw 

• The screw height adjustment mechanism is a mechanism that can adjust the height through a screw. 
• The mechanism is composed of a screw and a nut. By rotating the screw, the nut is driven to move up and down, so as to realize the height adjustment of the working surface such as the workbench.

Hydraulic motor

• The main drive is composed of a hydraulic motor, a planetary reducer, etc. The motor rotates forward and reverse to realize the forward and backward movement of the plate, which mainly provides torque for the rolled plate. The equipment has measures to prevent the steel plate from slipping. Each motor is equipped with an instant brake, which enables the rollers to accurately stop rotating during bending operation, ensuring precise positioning of the plate end, preventing the steel plate from slipping off the machine, and minimizing the remaining straight edges.

Electrical components

• Electrical components are famous brands, which is popular in market.
• Stable work ability.

Reducer

• The lowest backlash.
• The maximum output torque.
• The highest torsion rigidity 
• High efficiency high quality low noise , lift time lubrication 
• High precision, long life.
