Steel Forged Plate Rollers For Boiler , Chemical Industry /
The Function and Application Scope of the Machinery
This is threeroller symmetric rolling equipment. It is mainly used
in the process of cold working in which the sheets within
the thickness of 12mm can be bent into different diameter
It is widely used in boiler, chemical industry, mining,
construction, shipbuilding and other machinery industry.
Main Structure and Working Principle of Machinery
1, This is symmetric bending machine. The cylinder rolling is
completed by the upper roller which pressing to the lower one and
the mutual rolling.
2,The machine consists of two parts, the operation part and the
transmission part which are welded at the whole
bottom pallet. The operation part consists of left and right
bearing housing, one upper roller, two lower rollers,
lifting gears and some accessories. The lower roller is the main
one, upper roller can be adjusted at the height.
The transmission part consists with the main motor, speed-reducing
motor and other accessories.
3,The lower roller is driven by the main motor through the main
reduce. The main reductor output shaft transmits
to the two lower rollers through a group of gear wheel. The roller
driving direction is switched by the main motor.
4,The elevation movement of the upper roller is realized by the
auxiliary motor through the auxiliary reductor,
which drives worm and worm wheel under the left and right roller
bearing to move automatically, makes the steel
wire nut which is fixed on the worm wheel rotating, and completed
by up and down movement of ball bearing
5,The offloading device is used after the round cylinder have been
finished. Before leaving the left bearing seat,
raises the upper roller to standard height, and make the upper
roller stop with balance pull rod at the bottom of
upper roller. Then draw out pin shaft on the tilting bearing seat,
overturn the tilting bearing seat, then the coiled
product can emerge from one end of the upper roller.
6, The main components are: three 45 steel forged rollers,
HRC35-45, support frame is welded, process after being welded, the
lower pallet is a welded part. Ball bearing screw
andworm gear are 45 steel forged parts.
7, Electrical parts is adopted famous apparatus, steady
performance, durable, safe and reliable, operates conveniently.
