Method for processing antiwear texture of polyoxymethylene support ring

Abstract

The invention discloses a method for processing the antiwear texture of a polyoxymethylene support ring, which belongs to the technical field of surface engineering. A pulsed laser surface treatment device is adopted in the method and composed of a controller, a pulsed laser, a holophote, an extender lens, a focusing mirror, the polyoxymethylene support ring, a rotating table, an X-direction translational device, a Z-direction translational device, a stepping motor and a computer. The method comprises the steps: after the deoiling processing of the polyoxymethylene support ring, the polyoxymethylene support ring is installed on the rotating table, and the surface of the polyoxymethylene support ring is in the height range of texture processing by the adjustment of the Z-direction translational device; average laser power is adjusted in the range of texture processing, and the computer controls the scanning track of a laser focus on the surface of the polyoxymethylene support ring by controlling the X-direction translational device and the rotating table; and the pulsed laser surface treatment device is started to process the polyoxymethylene support ring. The invention has the advantages of high processing precision, convenience for processing, high efficiency, wide range of application, improvement of antiwear performance for the polyoxymethylene support ring and prolonging of service life of the polyoxymethylene support ring.

Description

technical field

[0001] The invention belongs to the technical field of surface engineering, in particular to an anti-wear texture processing method for a polyoxymethylene support ring, which uses laser processing technology to prepare a predetermined surface geometry on the surface of the polyoxymethylene support ring, which can be used for polyoxymethylene support rings and other materials Anti-wear texture processing. Background technique

[0002] Polyoxymethylene is a smooth, shiny, hard and dense material, and its wear resistance and self-lubricating properties are also superior to most engineering plastics. At a lower cost, polyoxymethylene is replacing some markets traditionally occupied by metals, such as replacing zinc, brass, aluminum and steel to make many parts. At present, polyoxymethylene is widely used in industrial machinery, automobiles, electrical and electronic, pipe fittings and irrigation supplies.

[0003] Polyoxymethylene has excellent comprehensive p...
