Abstract
The invention provides a nitriding method of slip sheets of a compressor. The nitriding method comprises the following steps of: (1) washing, namely washing out oil stains and dirt on the surfaces of slip sheet parts of the compressor by using alcohol; (2) loading, namely selecting different special working position apparatuses for vertically holding workpieces according to the slip sheets of different sizes and specifications; (3) treating, namely treating the slip sheets in a salt bath at the temperature of 650-780 DEG C for 100-200 minutes, wherein NH3 gas is introduced in the treating process and the NH3 flow is 2.1-3.2L/min in terms of 1000kg of salt bath solution; (5) cooling, namely after discharging, directly dipping the slip sheets in water and cooling for about 20 minutes; (6) washing, namely dipping the cooled slip sheets in clear water and washing for 5 minutes; and (7) polishing, carrying out roll polishing on the cleaned slip sheets for 150 minutes by a vibratory polisher to remove the superficial loose layer. According to the invention, the superficial wear resistance of the slip sheets, which are made of conventional stainless steel materials, of the compressor can be improved by adopting a liquid nitriding method on the basis of keeping the original rigidity, and therefore the service life of the compressor is prolonged.
Description
Technical field
The present invention relates to a kind of nitriding method of compressor part, particularly the nitriding method of compressor sliding blade.
Background technology
Rotating air conditioner compressor gets a lot of applications because it has efficient height, compact construction, volume is little, lightweight, important original paper slide plate as compressor, need to be close to the eccentric rolling piston of compressor, therefore the contact part of blade and piston is is very easily worn and torn, and needs preferably sliding capability, resistance to fatigue and erosion resistance.Slide plate is generally made by steel, and its hardness of common iron, resistance to abrasion etc. all are difficult to satisfy the job requirement of compressor, for wear resistance, anti ageing property and the erosion resistance of the sliding surface that improves slide plate, need to do surperficial nitriding and process.
But along with environmental protection, energy-conservation and consumption reduction are required to improve constantly, the pressure of low fluorine, floride-free refrigerant is used on the referred agenda.To requirements at the higher level are arranged in intensity, wear resistance, resistance to fatigue and work-ing life of slide plate, without surface Hardening Treatment slide plate can't satisfy the high loading compressor to its wear resistance and the requirement in complete machine work-ing life.
Summary of the invention
Technical problem to be solved by this invention is that the operating pressure that solves existing compressor of air conditioner increases substantially the problem that compressor sliding part that rear existing employing rapid steel makes can't be satisfied the demand.
The present invention solves the problems of the technologies described above the technical scheme that adopts:
A kind of nitriding method of compressor sliding blade, described compressor sliding blade prepares with the following method,

(2) cutting, setting: the shape according to slide plate cuts out slide plate with wire cutting method, mills out groove with milling cutter again;
(3) vacuum heat treatment;
(4) grinding, polishing: six faces according to slide plate carry out respectively grinding, polishing;
(5) gas nitriding: the slide plate after grinding, the polishing is carried out the ammonia nitriding;
(6) grinding: the slide plate after the nitriding is ground to the surface again and meets the requirements;
Described stainless steel is C 0.8-0.9, Cr14-15.5, V 1-3, Mo≤0.65, Ni≤0.55, Mn≤0.85, Si≤0.2, P≤0.01, the stainless steel of S≤0.02 (weight percent);
Described nitriding method concrete steps are:
(1) clean: with greasy dirt and the foul of alcohol flush away except the compressor sliding blade piece surface,
(2) load: according to the slide plate of different size, specification, select the vertical place work piece of different Special station tools,
(3) process: the temperature of salt bath is 650～780 ℃ during processing, and the time is 100～200 minutes, passes into NH during processing
3Gas, by per 1000 kilograms of salt bath solutions, NH
3Airshed is 2.1～3.2 liter/mins of clocks,
(5) cooling: after coming out of the stove, directly be immersed in the water cooling, about 20 minutes of cooling time,
(6) clean: after the cooling, immerse clear water and cleaned 5 minutes,
(7) polishing: the slide plate after cleaning, through vibratory finishing machine roll cast 150 minutes, remove the surface porosity layer;
The salt bath treatment solution is comprised of following constituent and weight percent:
