rolling Machine(horizontal Down-type)
three roll / four roll bending Machine
This machine is a hydraulic three-roll plate bending machine, designed to roll steel plates into cylindrical, circular-arc, conical shapes and perform circle straightening.
For the processes of rolling and circle straightening, all three work rolls are driven to provide the rolling torque required for plate forming.
The equipment is controlled by a PLC system, with a synchronization accuracy of �±0.20 mm.
A cone rolling device is installed on the bearing block of the lower roll. The schematic diagram of cone rolling is shown below.
The hydraulic control system adopts an integrated valve block design for easy maintenance, ensuring excellent functionality and operational reliability of the equipment. It is equipped with an oil filtration system and an industrial chiller cooling system.
The system pipelines are neatly arranged for convenient operation; the metal oil pipes in the hydraulic circuit feature natural and rational bending.
The hydraulic system is equipped with a monitoring function that tracks all key pressure output points and oil temperature of the hydraulic system. In the event of a fault, the system will automatically shut down and trigger an alarm, while indicating the fault location.
The entire machine is configured with both CNC and manual control systems that can be switched conveniently, boasting strong anti-interference performance, a long service life, vibration resistance and stable operation. The control system is integrated with screen display, calculation, program control, process parameter storage, soft protection and human-machine interaction functions. Two operation control cabinets are provided, one of which is movable around the equipment.
