Explanation of the use of four-roller rolling machine

        Plate rolling machine is a kind of public forging machine equipment that can bend non-metallic plate into cone, sphere, cylinder or other shapes. Construction and machine building.

        The four-roller plate rolling machine is suitable for the bending and forming of sheet metal. It can roll round, arc, and conical workpieces within a certain range. The metal plate can be roughly leveled on this machine.


        The function of the four-roller plate rolling machine is the same as that of the ordinary plate rolling machine, that is, it is used to roll the plate. Generally, it can be rolled into cones, spheres, and cylinders. Very extensive. In this machine, there are four rollers. Therefore, the form of roller movement is different from that of the three-roller plate rolling machine, but the working principle of these two is the same. Both use the three-point fixed circle. It is rolled on a principle to form different radii. The upper and lower rollers perform linear motion to clamp the plate, while the rollers on both sides perform linear or arc motion, and move closer to the upper roller to adjust the roll curvature radius.

        The four-roll rolling machine is used for the pre-bending and rounding of cylinders in pressure vessels, machinery, hydropower, construction and other industries, and has the functions of rounding and leveling. The main drive of the upper roller hydraulic motor drives the lower roller and the side roller to rotate by the friction between the steel plate and the roller, providing torque for rounding. The lower roller, side roller and tipping frame are hydraulically driven. The lower roller is raised and lowered vertically, and the side roller is inclined to rise and fall. The pre-bending clamps the steel plate by raising the lower roller, and the side rollers are inclined to rise to realize the pre-bending of the end of the plate.

        Plate rolling machine is an important equipment in industrial production. Today, our special manufacturers will explain the knowledge about plate rolling machine for everyone. I hope that everyone can learn by new knowledge to improve themselves, so that they can have more understanding and harvest.
