Abstract
The invention provides a surface treatment technology of an air-conditioning bearing lining. The surface treatment technology mainly comprises the following steps: cleaning the surface of the air-conditioning bearing lining to be treated; performing carburizing treatment; performing laser surface modification; and coating glaze on the surface of the air-conditioning bearing lining for performing rust prevention and the like. The surface treatment technology is simple and easy to operate. The air-conditioning bearing lining after surface treatment has high wear resistance, high corrosion resistance and good metal luster, and is suitable for large-scale production and manufacturing.
Description
Technical field
The present invention relates to wrapping film manufacturing process, particularly relate to a kind of process of surface treatment of air-conditioning bearing inner sleeve.
Background technique
Bearing inner sleeve be through harden and precision machining form.The tolerance of size of standard level inner ring and geometric accuracy meet P0 class precision.When using needle bearing, use inner ring that bearing can be made to reach normal working gap after mounting.Workpiece processing, transport, the process such as to deposit, surface is often with residual molding sand, welding slag, dust and the oil of scale, iron rust molding and other dirts.Coating is wanted to adhere on the surface of the workpiece securely, just must clear up workpiece surface before application, otherwise, not only affect combination force and the corrosion resistance of coating and metal, even if but also parent metal can be made also to continue corrosion under coating protection having, make disbonding, affect mechanical property and the working life of workpiece.Therefore the surface treatment before workpiece japanning obtains superior in quality protective coating, extends important guarantee and the measure in product working life.
Summary of the invention
The invention provides a kind of process of surface treatment of air-conditioning bearing inner sleeve.For realizing object of the present invention, technological scheme of the present invention is as follows:
A process of surface treatment for air-conditioning bearing inner sleeve, is characterized in that, its concrete steps are:
(1) surface cleaning is carried out on the surface of pending air-conditioning bearing inner sleeve, the attachment on the surface of removing air-conditioning bearing inner sleeve;
(2) in dust free room, with electrostatic gun, carbon dust is sprayed onto the surface on the surface of air-conditioning bearing inner sleeve, forms carbon-coating;
(3) with laser, laser remolten and laser transformation hardening process are carried out to the carbon-coating that the surface of air-conditioning bearing inner sleeve is formed;
(4) with spray gun or sprayer, glaze atomization is sprayed onto the surface of air-conditioning bearing inner sleeve, forms even oil reservoir.
Preferably, in step (1), surface cleaning mainly adopts Ultrasonic Cleaning, and remove the oil of tank surface, wax and oxide layer, ultrasonic time is 30-50min.
Preferably, in step (4), oil reservoir is a kind of in the antirust oil reservoir of water dilution type, solvent cutback rust preventing oil layer, the dual-purpose oil reservoir of anti-rust and lubrication or sealed anti-rust oil layer.
Beneficial effect: the process of surface treatment that the invention provides a kind of air-conditioning bearing inner sleeve, its key step comprises surface cleaning-Carburization Treatment-laser surface modification-scribble antirust treatment etc., this manufacturing process is simple, surface treated air-conditioning bearing inner sleeve has higher wear resistance and antiseptic property, and there is good metallic lustre, be applicable to mass production manufacture.
