Product Description Experience the pinnacle of engineering with this cutting-edge Hydraulic Four Roll Machine, a true marvel in plate rolling technology. At its heart lies the top roller, the critical driving force that delivers the precision and sophistication that our esteemed clientele demand and deserve. It serves as the cornerstone of the drive mechanism, gracefully executing rotational movements with unmatched elegance. The lower roller, in a symphony of motion, ascends and descends, guiding the steel plate with unparalleled precision while ensuring meticulous friction alignment. The two side rollers, with their seamless up-and-down angular motion, masterfully sculpt the steel plate into the desired form. With an innovative adjustable side roller, this machine excels in achieving both symmetric and asymmetrical bending with minimal flat ends, far surpassing traditional three-roller machines by eliminating the need for cumbersome pre-bending procedures and devices. Additionally, it provides rough leveling of the steel plate, making it an indispensable asset across various industries, including petroleum, chemical production, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.Machine construction:The sophisticated architecture of this machine is defined by its upper roller device and driving unit, lower roller device,side roller apparatus,hydraulic drop end system, lubrication unit, resilient left and right frames, a robust chassis, and additional components.(body frame drawing)top roller and driving assemblyThe Top roller device is equipped with a top roller, an advanced hydraulic drop end, fixed bearing, hydraulic motor, and bearing, all harmoniously synchronized. The top roller transmits torque through a precisely connected hydraulic motor, initiating its smooth and efficient rotation. The hydraulic drop end is meticulously equipped with a protective steel bushing to ensure seamless operational integrity.movement. This hydraulic drop end is expertly equipped with a protective steel bushing to ensure seamless operation.lower roller and position inspection unitThe lower roller device is engineered with a lower roller, an oil cylinder, a lower roller bearing, and a self-aligning bearing, all meticulously designed for peak performance.Each sliding bearing block, crucial in supporting the lower roller, aligns perfectly with the frame guide rail. Mounted on dual oil cylinders, the hydraulic system empowers the lower roller's up-down movement. Operating at a rated pressure of 16Mpa, the primary oil cylinder ensures precision, with sensors accurately tracking the up-down distance, displayed on an LCD for real-time monitoring. This adjustable hydraulic system offers precise power to achieve the desired rolling force, enhancing accuracy to a superior level.(hydraulic drivers drawing)side roller apparatusThe side roller device is masterfully crafted, incorporating the side roller's main oil cylinder, self-aligning bearing, and essential bearings.Bearing blocks provide steadfast support to the side roller, with each side effortlessly coordinating with the frame's guide rail for optimal functionality.The side roller bearing block's up-down movement is driven by four strategically placed oil cylinders within the frame. Sensors, installed on both the side rollers and frame, provide precise measurements of movement, displayed on an LCD for easy and intuitive monitoring.To create a stunningly refined cone shape, self-aligning bearings are crucial for both side and lower rollers. With meticulous adjustments to the lower roller level and alignment, the rollers incline, achieving a snug fit and inducing a precise degree of inclination relative to the horizontal plane.3-4, hydraulic drop endThe hydraulic drop end device is fortified with robust oil cylinders, joints, bearing blocks, and more, ensuring efficiency and reliability.The hydraulic drop end system ensures effortless product removal along the Roller shaft, streamlining the operational workflow.Upon completing hydraulic drop closure or opening, the oil cylinder's stroke is ingeniously reset to zero, maintaining exceptional precision.A state-of-the-art hydraulic station reliably powers the system, ensuring consistent and optimal performance.Balance device Ingeniously crafted to revolutionize balance, our state-of-the-art device boasts a cutting-edge, compact structure that ensures unparalleled performance. As the tipping rack elegantly pivots from the bearing face of the top roller and begins its graceful tipping motion, this advanced balance apparatus steps into action. When gravity naturally tugs the top roller's end downward, this expertly designed mechanism maintains perfect equilibrium, strategically positioned on the fixed side. This precise placement, at a meticulously calculated distance from the fixed frame, is securely anchored by premium screws, guaranteeing unwavering stability and exceptional operational efficiency.(plate rolling drawing)Hydraulic SystemOur hydraulic system is nothing short of a masterpiece. Meticulously assembled with a high-precision gear pump, an intricate valve group, and premium auxiliary pipelines, it ensures flawless operation.The hydraulic valve incorporates the renowned Yuken superposition series, ingeniously ensuring that the pipeline layoutisremarkably intuitive, dramatically reducing leakage and simplifying maintenance, culminating in exceptional efficiency.This sophisticated architecture boasts three distinct loops: the pressure adjusting loop, synchronization loop, and speed loop, each meticulously contributing to harmonious and efficient operations.The pressure adjusting loop skillfully modulates the system’s working pressure via the main overflow valve, achieving a robust pressure of 16Mpa, ensuring consistent performance.The synchronization loop deftly fine-tunes the synchronized movement of the lower roller through precise flow dividers and throttle valves, allowing impeccable speed adjustments.The speed loop artfully governs frame descent, reset operations, and speed calibrations with precision, utilizing the adept throttle valve.Electric Control System Our electric control system is a marvel of engineering, featuring a seamlessly integrated electric cabinet, an advanced operation control table, and a versatile portable button box, all operating at 380V/50Hz. It is equipped with robust short circuit and overload protection for the main motor, employing an AC contactor for managing both positive and reverse rotations. Through the power of PLC programmable control technology, this system minimizes relay usage, enhancing stability and longevity. Strategically placed buttons and indicator lights on the control table ensure the entire rolling process is streamlined, efficiently managing every operational aspect with precision.CNC System The NC system is a paragon of reliability, featuring a rotational encoder and a high-reliability industrial controller, creating a steadfast and dependable control platform. CNC Function CThis advanced NC system provides unparalleled real-time monitoring, effortless data transmission, and dependable power-off memory throughout the entire rolling process, ensuring efficiency and reliability. The industrial control PLC meticulously inspects the lower position and both ends of the side roller, guaranteeing synchronization precision with an impressive ±0.15mm accuracy.The state-of-the-art programmable display offers comprehensive real-time visibility of the lower roller and side roller end positions,and these parameters can be effortlessly configured and set to meet precise requirements.With an extraordinary displacement transducer resolution of 0.10mm, the display precision achieves an impressive ±0.10mm accuracy.Automatic Self-Judge Function Manufacturer of the Standard PartsNAMEManufactureBearingsType Double row aligning bearing Manufacture WafangdianRollers Material 42CrMo forging upper roller and 45# steel other rollersManufactureNangang/Warwick Steel Body frameMaterial Q235AProcessing methods Welded structural parts, annealing stress - shot blasting, CNC boring and milling machine machining ManufacturePully Hydraulic driverJieshite Hydraulic motor Nantong tongdeMain electrical elementSIEMENSHydraulic systemPump Type Gear pumpManufactureChangyuan Valve Manufacture YUKENcylinderPiston rod45 Forgings, Heat treatment HRC48-52 ManufactureNantong Sealing Yx Manufacture NOK/dingjiElectric system digital control systemHydraulic motorNantong tongdeTouch screenHaiwei 15.6'PLCXINJE Sensor Milante Main electrical elementSchneiderElectric/Siemens
