1.Machine use variety
This device is 3 rollers symmetrical mechanical rolling equipment. It is utilised to bend metal into drums
shape with different diameters. And it is commonly employed in boiler business, chemical industry, mine industry, constructing industry, shipbuilding sector.

three.Main structure and operate basic principle
A.This equipment is symmetrical rolling equipment, down up roller and then enable up and down roller do
reverse roll to bend steel plate.
B. This machine composed of two components individuals are working component welded in complete chassis and moving part. Doing work part composed of still left and appropriate bearing base, one up roller, two bottom rollers (the substance of the three rollers is 45#metal and do warmth treatment), lifting screw and turbine and other accent elements. Down rollers generate up roller to move, up roller can do up and down transfer by peak way. Generate portion composed of principal motor, principal speed reducer and other accessory components.
C. Bottom rollers had been drove by major motor by means of main pace reducer, output spind
le of primary pace reducer pushed to two down rollers by one team gears, the revolve direction of rollers adjusted by principal motor.
D. Higher roll lifted by accessory motor by means of vice velocity reducer drive worm and worm wheel mechanism of appropriate/still left rolls bearing base. That to enable the lifting pole do up and down transfer.
E. Unloading device is developed to eliminate the workpiece following drums bended into shape. Before unloading the upper rolls move to up limit situation, the equilibrium device on upper rolls ends strike upper rolls, draw out the spindle of the pin, then to take away the workpiece.
