Plate 3 Roller Bending Machine / Sheet Metal Roller Machine Mechanical
The machine widely used in petroleum, chemical industry, cement, bioler, shipbuilding,
aviation, water conservancy, power transmission towers and other machineary and
equipment. Its working principle is rotating bending deformation. For the upper roller
can be woved no matter up and down, but also horizontally, so no need additional press
or equipment, can realize bending, as well as correction of the workpiece
Main Working Principle :
this plate rolling machine is upper roller adjust type, and upper roller in middle of two
down rolls and drove by lead screw to move up/down and to bend the steel plate.
the equipment composed of working parts and drive system two parts. The working parts
composed of right and left bearing plate , one upper roll, two down rolls (these three rolls
material is 45# steel with heat treatment), lifting screw and worm wheel and other accessory
parts. Down rolls drive upper rolls to move. Upper rolls can adjust up/down. Drive system
composed of main motor, main speed reducer gear and other accessory parts.
down rolls were drove by main motor and main speed reducer gear, the spindle of main
speed reducer drive two down rolls by one group gears, the direction adjusted by the
upper rolls lifted by accessory motor and vice speed reducer drive worm pole and worm
where of right/left rolls bearing plate.
unloading device is used for bending circle type to remove the work piece. while unloading
the upper rolls move to up limit position, the balance device on upper rolls ends hit upper
rolls to remove the work piece.
Machine Usage Range:
This plate bedning machine is three rolls machine, upper roller can adjust. It is used to
bend different diameter of steel into circle sharp. And it is widely used in chemical industry,
ships industry and so on.
