Max. Thickness of plate
Max. Pre-bending thickness
Max. Width of plate
The length of working rolls
Up roller diameter
Bottom roller diameter
Side roller diameter
Minimum bending diameter
φ480mm (non-full loading)
It’s easy to operate,rich shape bending
Double pre-bending without return
Aligning the material is convenient and accurate,avoid wrong side phenomenon
Once forming,the productivity is higher 50%-80% than three rolls plate bending machine
The top and bottom roller clamp the plate during rolling without slipping
The minimum bending diameter of cylinder can get to 1.5times the diameter of top roller,there almost no flat edge.
W12 Series is 4-ROLLER rolling machine. The up roller is main drive roller ,through the output gear of the reducer connected with the upper gear to provide torque when rolling. The down roller make vertical movement ,the force is collected through the hydraulic oil force with the piston in the hydraulic tank to tight the plate and hydraulic transmission. There are side roller in the two sides of the down rollers who make inclined movement along the make guide, it is hydraulic drive. The machine has large advantage is the pre-bending and the rolling can be achieved in one machine.
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 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 working-pieces.
There are moveable independent operation table for easy moveable operation. The machine has been equipped with security linked equipment. 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.
The machine is equipped by four working rollers, left-right machine shaft, basement, cone rolling equipment , dumping parts, transmission part and relate sensor section, hydraulic system and electrical system
