Main structure and work principle
This machine is symmetrical rolling machine, down up roller and then let up and down
rollers do opposite roll to bend steel plate.
B. This machine composed of two parts those are working part welded in whole chassis and moving part. Working part composed of left and right bearing base, one up roller, two bottom rollers (the material of the three rollers is 45#steel and do heat treatment), lifting screw and turbine and other accessory parts. Down rollers drive up roller to move, up roller can do up and down move by height way. Drive part composed of main motor, main speed reducer and other accessory parts.
C. Bottom rollers were drove by main motor through main speed reducer, output spindle of main speed reducer driven to two down rollers by one group gears, the revolve direction of rollers adjusted by main motor.
D. Upper roll lifted by accessory motor through vice speed reducer drive worm and worm wheel mechanism of right/left rolls bearing base. That to let the lifting pole do up and down move.
E. Unloading device is designed to remove the work piece after drums bended into shape. Before unloading the upper rolls move to up limit position, the balance device on upper rolls ends hit upper rolls ,draw out the spindle of the pin ,then to remove the work piece.
IV. Material and quality of roll shaft and process art
A. The material of rollers-- 45# steel.
B. Manufacturer-China
C. Process art- cast steel ingot—forge semi finished product­—fire treatment after forge—rough treatment by lathe—heat treatment—accurate treatment by lathe—quench in surface.
D. Requirements of heat treatment: quench in surface--osmosis depth of quench≥ 3mm (single side), strength≥HRC45-50.
Welding joint components
Includes--rack of machine, base,and other steel components.
Art-flow of welding components
Inspect plate—pre-handle plate—provide material—process the mouth of slope—
welding—inspect weld bead—anneal treatment—rough prose­­—vibrate limitation—accurate treatment—rust cleaning in surface, corrosion prevent—paint.
