Universal upper roll plate rolling machine/Universal upper roll plate banging machine

The main drive system of this plate rolling machine adopts a hydraulic motor combined with a planetary reducer to directly drive the rotation of the upper working roll and provide the torque required by the plate rolling machine, and the speed can be adjusted according to the plate rolling process requirements. Compared with the traditional transmission mode, it not only greatly reduces the floor space, but also avoids the inconvenience in installation and adjustment of the traditional transmission mode, facilitating the installation of the machine and transportation during site relocation. At the same time, it also avoids the transmission instability caused by inconsistent pressure resistance between the main machine and the transmission part during the foundation construction.

Working Principle

The upper roll can realize vertical lifting and horizontal movement. The vertical displacement is driven by hydraulic transmission, which provides strong and stable pressure to ensure that the plate is subjected to uniform force during the rolling process. The horizontal movement is realized by mechanical transmission to ensure the accuracy of positioning. The lower roll is a driving roll driven by a motor reducer, which provides stable driving force during round rolling. The elevation of the lower roll remains unchanged, facilitating the feeding and operation of the plate.

Performance Features

Versatile Functions: It integrates both pre-bending and round rolling functions. After a single feeding, it can complete the pre-bending and forming of both ends of the plate without turning the plate around, and can also be used for the correction of formed workpieces.

High Bending Precision: Digital display devices are equipped for the vertical and horizontal movement of the upper roll, enabling convenient operation and accurate control, and the straight edge length can be set freely. The upper roll applies direct pressure for pre-bending, achieving high-precision end pre-bending.

Superior Product Precision: The upper roll is drum-shaped, and the two lower rolls are driving rolls with fixed positions. An arc is formed by three tangent points where the three rolls contact the metal plate to bend the flat plate, making it possible to roll ideal products within a wide range.

Rich Bending Shapes: It can roll workpieces of various shapes such as O-shape, U-shape and multi-segment R-shape. It can also realize multiple bending forms including backward bending, forward bending and combined bending by adjusting the position of the upper roll and the rotation of the lower rolls.

The whole machine is equipped with CNC and manual control systems that can be switched conveniently, featuring strong anti-interference, long service life, shock resistance and stable operation. The control system has the functions of screen display, calculation, program control, process parameter storage, soft protection and man-machine interaction. Two operation control cabinets shall be provided, one of which is movable around the equipment.

Application Fields

It is suitable for the manufacturing industries of mechanical equipment such as petroleum, chemical industry, cement, shipbuilding, boiler, aerospace, water conservancy and power transmission tower. It can roll steel plates into cylinders, cones, multi-R, U and R shapes at room temperature, and is used for the

processing and rolling of parts such as circular and conical tanks.
