Abstract
The invention provides a process for remanufacturing a corrugator roll. The process comprises the following steps: (1) early treatment: (a) degreasing and removing oil; (b) removing rust; (c) phosphorizing; (d) blasting sand; (2) spraying: spraying an Ni-Cu-W coating by adopting high velocity oxygen fuel spraying equipment; (3) post-treatment, namely polishing by a fiber grinding wheel. By adopting the Ni-Cu-W coating, the microscopic tissues of the coating on the surface of a material can be improved, the abrasion resistance of the material surface can be integrally improved, and the process has a remarkable effect of enhancing the corrective comprehensive mechanical performance; cubic boron nitride is a hard material second to diamond, has excellent physical and chemical properties, the hardness and abrasion resistance of the surface of the corrugator roll can be greatly improved by adopting a cubic boron nitride auxiliary, so that the service life of the corrugator roll can be prolonged and the maintenance cost can be reduced.
Description
Technical field
The present invention relates to re-manufacturing technology field, specifically a kind of Corrugator roller manufacturing process again.
Background technology
Corrugator roller is most important integral part in corrugated board production device, and it generally all adopts 48CrMoA steel, and through medium frequency quenching or nitriding treatment, its hardness is general all at more than HRC55.Corrugator roller is the important vital part of single-side machine.Corrugator roller is divided into upper corrugated roller and lower corrugated roller, and upper and lower roll surface is female shape, and two roller mating engagement assemblings, its meshing mechanism is different from common geartransmission.Lower corrugated roller is drive roll, and axle head is equipped with gear, and electric motor drives lower corrugated roller to rotate through deceleration device.Upper corrugated roller is driven roll, relies on the roller tooth of top roll and the roller tooth of lower roll to engage each other transmission.May be there are some defects in Corrugator roller, such as pit etc. after use after a while, if Corrugator roller occurs these defects, will likely cause manufactured quality of corrugated low, but also likely cause Corrugator roller to use.If scrapped for some defective Corrugator rollers, very large waste will be caused, so manufacture extremely important again to the reparation of defective Corrugator roller, the work-ing life of Corrugator roller can not only be extended like this, and can also maintenance cost be reduced.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Corrugator roller manufacturing process again.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of Corrugator roller manufacturing process again, comprises following processing step:
