DESCRIPTION
Universal W11S Hydraulic rolling machine with prebending
1.The Feature of Hydraulic Plate Rolling machine :
-The machine widely used in petroleum, chemical industry,
cement, boiler, shipbuilding, aviation, water conservancy, power transmission
towers and other machinery and equipment. Its working principle is rotating
bending deformation.
– A cylinder can be rolled, including the pre-bending of
both ends, feeding the plate forward through the rolls, one time only. The
operator should find one only position for each side roll, to get part
finished. Permanent lubrication technology(bearing life period without
refueling).
2.The whole structure of Hydraulic Plate rolling machine
:
-Totally European design,streamlined looking,frames of
our machines are fabricated, welded steel (ST-52). Roll shafts, materials and
bearings used in production are European quality. Also the torque limit of the
machines is very high. NC playback and CNC graphic control systems are
available as optional accessory.
– The main structure of the equipment includes upper
roller, lower roller and horizontal movement mechanism, supporting
mechanism,main drive mechanism,downturn system, left and right machine frame,
chassis and balance mechanism, hydraulic and electrical control systems.
– It allows for excellent roundness, thanks to the
Planetary movement of the side rolls (PRIMA patent), moving them to the center
of the machine (the tightest geometry available), compared to the inclined
linear guides of other brands that, especially on large diameters, move farther
away from the central roll and the plate clamping.clamping pressure is
adjustable(no-existent skidding,productivity is 80% than three roller plate
rolling machine).
3.The Feature of Hydraulic Plate Rolling machine :
– High precision pre-bending, freely setup the width of
plate. Upper roller presses the plate end for pre-bending.
– Upper roller likes drum with collaboration of carrier
roller permit continual bending of any thickness of plate.
-Safe work, fixed two down roller, upper roller does
horizontal and vertical movement, and the plate don’t move during upper roller
moving.
-Unitary structure, convenient to move the whole machine
as machine has a hardy under pan. No need to anchor bolt.
– Different use has different control way, like top
numerical control and below numerical control.
-Through exclusive technology, PRIMA 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 (bull nosing) on the minor diameter edge.
