HOGI CNC 4-roller plate rolling machine has the function of pre-bending at the end of the plate, which can load the metal plate at one time and complete the pre-bending at the end of the plate and the rolled shape of the workpiece without adjusting the head. The upper working roller of the machine is the main driving roller, the lifting and lowering of the lower roller and both side rollers adopt hydraulic transmission, the lifting and lowering displacements are controlled by computer, automatic leveling and screen display, the tipping and resetting of the overturning bearing body adopts hydraulic transmission, and the tail of the upper rollers is equipped with a balancing mechanism, so that it is easy to unload the rolled up workpiece and the cylinder body. It is equipped with a mobile independent operating table, which can be moved and operated at any time, and the machine is equipped with a safety interlocking device, which is of high technical level, full-featured, high-precision and easy to operate. It is the ideal machine for rolling round, arc and cone-shaped workpieces in energy, transportation, petroleum, chemical, boiler, shipbuilding, ventilation, metal structure and other industries.

HOGI 4-roll CNC plate rolling machine is suitable for bending and forming work of metal plates, it can roll round, arc and a certain range of conical workpieces, and has the function of pre-bending at the end of the plate, the remaining straight edge is small, and the working efficiency is high, and it can be roughly calibrated to the metal plates on this machine.

Four-roller plate rolling machine consists of four rollers, the upper roller is the main drive and the position of the upper roller is fixed, and the two ends of the lower roller are driven by hydraulic cylinders to lift. Then the lower roller down, the two side rollers rise, plate bending rolled into a cylindrical shape. Two side rollers straight line or arc to the upper rollers close to the movement to adjust the curvature radius of the roll.

Advantages of four-roller CNC plate rolling machine:

Can pre-bend the plate end of the metal plate, and the remaining straight edge is small, without the need for additional equipment such as presses pre-bending has a good process adaptability and high efficiency.

Compared with the 3-roller coiler, it can not use other equipment to directly pre-bend the end of the plate, and the remaining straight edge is smaller. This not only improves the quality of the workpiece, but also the process is simple and easy to operate. Rolling machine manufacturers tell you that the four-roller plate shearing machine is a hydraulic transmission, than the mechanical transmission, low noise, high efficiency, low energy consumption, compact structure, maintenance and easy to use. Suitable for heavy workpiece rolling and automation level and high technology level occasions.

HOGI Four-roller plate rolling machine has the function of aligning and clamping the plate, the plate will not slide and run out of shape; it has the function of anti-overload and hydraulic protection; it is easy to be operated with high speed and high efficiency in rolling the plate.

The working principle of the four-roller plate rolling machine, for the plate processing of material properties and shape of the different problems, designed based on machine vision of the four-roller plate rolling machine of the numerical control system, able to detect the curvature of the rolled plate online, and the required shape for comparison, real-time correction of the processing parameters, to solve the problem of changes in the rebound coefficient of the differences in the performance of the plate material in the processing of rolled plate; to complete the linkage of the upper roll and the side roll to solve In addition to round, such as elliptic, parabolic and other anisotropic parts of the rolled parts, to realize the CNC rolled plate processing.
