Note the use of rolling a wheel, rolling machine accuracy, vibration, does not operate under normal service; 2, rolling the die-bit errors on the rolling wheel is rolling occurs axially displaced by the cut-and-tooth pattern squeeze two stress; 3, is uneven rolling green silk thread size, the surface is not clean, there is foam wheel, scale and filth; 4, is unevenly rolled pieces of hardness (8.8 bolts should be at 27 ~ 30HRC; 10.9 level applications in 35 ~ 37HRC), sometimes because of mismanagement will prevent without tempering high hardness (50 ~ 55HRC) quenching and tempering pieces blend into pieces in Dongguan rolling wheel supplier, its hardness and rolling wheel tooth pattern cutting edge hardness similar wholesale Dongguan rolling wheel, causing chipping. 5, did not join when rolling lubricant, causing friction, so cusp rapid temperature rises above the temperature of the fire rolling rolling wheel of reincarnation process, excessive temper softened tooth pattern, the occurrence of back teeth, dental heap failure; 6 before rolling round the factory must be fully demagnetized, leaving residual magnetism, work fine iron absorption due to tooth pattern foam will accelerate wear failure. Rolling wheels rolling machine common problems and treatment of common problems rolling machine and processing method, not silk or floss roll rolling head rotation is incorrect; rolling head size and reinforced inconsistent positioning sleeve incorrect order ; rolling head is correctly installed in the order; wheel positioning sleeve damage; 2, do not start the open air, inverted total stop to the closing; power phase; thermal protector for protection, insurance burn; wiring off, transformers have been burned bad. Control circuit contacts are damaged or bad. Check the stop-start button, whether the dropped loose; button contact is good; check the device in front of the limit contact is good, whether the contact line, insurance damage (transformer into and out of the insurance) MassMutual rolling wheel Wantong rolling round (certified), rolling wheels provided by the Dongguan City Hengli Huai Hardware electronic processing.
