Obvious abnormal noise, loud running sound and obvious vibration are common running faults of roll forming machines.
Main causes are worn and aging roller bearings, excessive fitting clearance of worn bushings, loose body fixing bolts caused by long-term vibration, and unreasonable chain tension.
Standard solutions: Check all forming roller bearings one by one and replace damaged ones in time; fully fasten all fixing bolts of machine frame and side plates; precisely adjust drive chain to moderate tension; replace severely worn bushings to completely eliminate abnormal noise and loud operation sound.
