2000mm 2500mm 3000mm Hydraulic CNC Four Roll Plate Bending Machine

GENUO hydraulic CNC HC4R Series 4 roller plate rolling machine has the pre-bending function of the plate end and the CNC rolling function.It can feed the metal plate at a time, and can complete the pre-bending and the roll forming of the workpiece without turning the head.

The upper working roll of the machine is the main drive roll, and the lower roll and both sides of the roll are hydraulically driven. The lift displacement is controlled by the computer and is automatically leveled. The screen display shows the synchronization accuracy of ±0.1mm. The tilting and resetting of the rollover bearing body is hydraulic transmission, the balance of the upper roll is equipped with a balance mechanism, which can easily take out the rolled workpiece. It has a mobile stand-alone console that can be moved at any time; the machine is equipped with a safety interlocking device and is safe.

Due to its full-featured, high-precision, and easy-to-use operation, this device is the ideal contemporary CNC coiling device. It is the ideal model for rolling circular and arc-shaped workpieces in energy, transportation, petroleum, chemical, boiler, shipbuilding, hydropower, and metal structure industries.

Working Roller   Roller is the most important components of the rolling machine, its quality and performance has a direct impact on the service life of the rolling machine and the precision of rolling. Working rollers are made of high-strength high-quality steel 42CrMo material, after forging, roughing, quenching and tempering, HB240 ~ 300, finishing after the intermediate frequency quenching HRC47-58, according to JB/ZG4289-86 roll steel standards. Strictly in roller manufacturing, to ensure its comprehensive mechanical properties.

Electrical Components   Germany SIEMENS electrical components ensure the stable operation of the machine. Reasonable line connection and arrangement greatly reduces the failure rate. The integrated control module of hydraulic valve group makes the sliding block move smoothly and accurately. And the operator and all parts of the machine played a good protection. It's safe, stable and not easy to break. Low Noise and Powerful Force Siemens motor guarantee the machine service life and improve the machine working stability.

CNC Control System

Thanks to the CNC control and PLC of SIEMENS. Excellent HMI operation interface. Make our bending machine run at will. SIEMENS Smart Line provides a friendly interface for users to monitor the operation of machines in the control system.
GENUO Rolling machine equipped with special independent operation panel and automatic rolling program so that can realize one-button operation. This machine can automatically rolling and forming at one time.
Powerful data storage and recall functions. Hundreds of programs for arious specifications of automated rolling. The system is compatible with manual operation programs and can be manually operated when needed.
At the same time, the configuration software also provides users with a variety of functions, such as formula management, security level management, language management, etc.

Roller Rotation

Hydraulic Motor - Planetary Gearbox - Working Roll

The upper roller is a driving roll of 4 roller bending machine. The independent hydraulic motor on the upper roll and the high-powerbox are directly coupled(straight), not through the intermediate gear transmission, which is the most energy-saving drive method.

The hydraulic motor is equipped with an immediate brake to allow the roll to stop accurately in the pre-bending state.

Hydraulic System

Each oil circut is routed with two relief vaive to control pressure.the maximum set pressure for each oil circuit is 25 MPa. which is mainly to control the main cylinder pressure. and the other relief valve is set to 16 MPa, mainly to control the overturning cylinder and balancing cylinder pressure.In order to ensure the synchroni-zation accuracy of the main oil cylinders at both ends of each moving working roll,high-precision displacement sensors are installed on the left and right racks and the tilting frames. Through the pressure sensors, the microcomputer control system detects and adjusts the movements of the main oil cylinder pistons to achieve the precison of the both working roller ends.

Advantage of our hydraulic system:
a. The unique pre-discharge technology is adopted to effectively avoid hydraulic shock and improve the life
of the pipeline and seals.
b. The hydraulic components are adopt Japan YUKEN and NO.K brand,hight qauality parts to ensure the
stability of the hydraulic system.
c. Each input and output port of the hydraulic system is provided with correspondina detection points, which
are convenient for maintenance and fault checking. The oil pump adopts a lower mounted type and positive pressure oil absorption. At the same time the filters, level gauges, and all transmitting devices can automatically warn of faults.

The machine is four roller plate bending machine, its structure shown as drawing, upper roller as initiative roller, down roller and side rollers as driven rollers; upper roller is fixed, down roller does up and down movement; upper roller is mechanical initiative, while down roller and side rollers are driven by friction from plate and rollers. Down roller and side rollers are driven by hydraulic oil tank to do lifting movement.
Upper roller’s ventro-bearing overturn and reset are also driven by hydraulic oil tank. Rollers’ bearing and oil tank are installed on left and right side of machine frame.
