Four-roll plate function will be a metal sheet material once on the material does not need to turn to finish the sheet end of the bending and roll forming, the remaining straight edge small, is a roll round, curved, conical workpiece ideal equipment.
According to the arrangement of the two sides roll adjustment position, can be symmetrical or asymmetrical bending, so the machine can be rolled into the theoretical residual straight edge is very small ideal cylinder, compared with the symmetrical three-roll plate machine does not need to use the pressure machine to the plate end of the bending.
The bending is raised by the lower roller, the end of the plate is clamped, and the side roll is tilted up to realize the bending of the plate end.
The lower roller and side roll displacement of the machine is controlled by the Intelligent PLC programmable controller, the automatic leveling, the screen digital display, the synchronous precision ±0.15㎜.
The lower roller and the side roll can be tilted at one end, and the same can be lowered in the inclined state.
The upper roller is mainly driven by the friction between the steel plate and the roller to rotate the side roll to provide torque for the coil. Hydraulic drive form, with synchronous hydraulic system to automatically speed balance between rollers, automatically compensate the upper and lower working rolls surface speed. Each hydraulic motor with an instant brake, so that the roller in the pre-bending state to achieve accurate stop rotation, and the remaining straight edge of the smallest.
The brakes should react quickly to ensure accurate positioning of the plate end and prevent the plate from slipping off the machine. The upper roller drive adopts hydraulic motor plus planetary deceleration drive, which has the advantages of small volume, light weight, compact structure, small footprint, high transmission efficiency and strong environment adaptability.
