1. High precision pre-bending, freely setup the width of plate.
Upper roller presses the plate end for pre-bending.
2. Upper roller likes drum with collaboration of carrier roller permit continual bending of any thickness of plate.
3. Safe work, fixed two down roller, upper roller does horizontal and vertical movement, and the plate don’t move during upper roller moving.
4. Unitary structure, convenient to move the whole machine as machine has a hardy under pan. No need to anchor bolt.
5. Different use has different control way, like top numerical control and below numerical control.
6.Through exclusive technology, Krrass can develop cones as easily as competitive machines can develop cylinders. And it eliminates scarring on the surface of shell or roll and also eliminates, in most cases, the need for grinding the lamination (bullnosing) on the minor diameter edge.
"YUKEN" from Japan
"NOK" from Japan
* High performance
* High efficiency
* High quality with low price
* Easy control
* CE & ISO9001:2000 certification
* Can bend many material such as carbon steel, stainless steel, aluminum, alloy and etc.
The upper roller rotates of four roller rolling machine for the mechanical rotation, the lower roller and the side roller in plate bending machine of 4-rolls are driven by the hydraulic drive, and the operation is controlled by electric centralized control. The machine can complete a feeding plate at both ends of the pre deformation and rolling cylindrical workpiece, arc, but also on the sheet metal shaping and leveling work, has a direct effect of pre bending, easy, material.
