The machine has pre-bending function for plate edge ,and can bend roll the plate one time without any thing re-rolling with combined procedure or prebending and bending roll into shape. The upper roller is the main drive roll, the down roller and two side rolls up-and-down movement is controlled by hydraulic drive. The up-and-down displacement of the down and side rollers are controlled by computer..Automatic leveling,display by screen , high synchronization precision ±0.2MM.Turnover bearing body dumping and reset is done through hydraulic transmission.The upper roll end has balance equipment to be convenient take of the rolled cylinder and workingpieces.There are moveable independent operation table for easy moveable operation.
Main structural features
1,The four-roller bending machine adopts a torsion-axis synchronous structure, and the four-roller coiling machine has high precision and roundness after being rolled up!
2,Full hydraulic motor drive, four-roller coiling machine is environmentally friendly and energy efficient.
3,Straight side is short and the pre-bending effect is good! More suitable for roll cones .
4,The four-roller reeling process is completed in one pass, including bilateral pre-bending. The four-roller reeling machine is fast, efficient, and easy to operate, requiring only one operator .
5,With automatic alignment and clamping function, the plate will not slide and run off.
6,The four-roller bending machine has anti-overload and hydraulic protection functions.
7,With anti-wear, permanent lubrication-free features.
8,The diameter of the reel is small (the four-roll bending machine can roll a cylinder that is less than 1.1 times the diameter of the upper roller, and the linear sliding-guided rolling machine can have a diameter of 1.4-0.5 times the diameter of the upper roller).
The machine is suitable for bending and forming of metal plate,and can do rounding cambering word,and coning work in a certain rang,The machine has a plate-end pre-bending function,and the width of remaining straight edge is small,and has high word efficiency. It can do rough plane calibrating of metal plate. It is ideal bending roll machine for all kinds of metal working industry like energy, transportation ,petroleum, chemical, shipping-building, boiler with high technology, full function, high precision and easy in operation character.
