4-roller plate bending machine GJW12H-25X2500

hydraulicautomaticwith mobile control panel

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 pre-bending and bending roll into shape. The upper roller and the down roller are the main drive rolls, 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 working pieces.There are moveable independent operation table for easy moveable operation.  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.
