At the forefront of innovation, this state-of-the-art machine stands as a four-roller plate rolling marvel, where the top roller reigns supreme as the pivotal component. It serves as the primary drive, executing rotational movements with precision. The lower roller gracefully moves up and down to guide the plate with elegance, ensuring that friction aligns seamlessly lengthwise. The two side rollers ascend and descend at an angle to impart the desired plastic deformation to the steel plate. With its adjustable side roller, this machine adeptly achieves both symmetric and asymmetrical bending, resulting in minimal flat ends, outperforming three-roller machines by eliminating the need for pre-bending procedures and devices. Furthermore, it provides rough leveling of the steel plate, making it indispensable across industries such as petroleum, chemical, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.
Machine construction:
The refined core structure of this sophisticated machine includes an upper roller device and driving unit, lower roller device, side roller apparatus, hydraulic drop end system, lubrication unit, left and right frames, chassis, and more.
