Embodiment Construction

[0015] A production process for enameled wires for R134a compressors according to the present invention, the entire production process is: extrusion→painting, baking→on-line detection→winding, the specific steps are as follows:

[0016] Extrusion process: Oxygen-free copper rods produced by continuous casting and rolling process, check that the water pressure of the outer circulation is not less than 0.3Mpa, and the air pressure is above 0.4Mpa. After turning on the main power supply, check whether the hydraulic pump, lubricating pump, tooling cooling pump, product cooling, etc. are working normally. Close the boot seat, press the compression cylinder, check that the system pressure is about 10Mpa, and the boost pressure is about 40Mpa. Start the main machine, adjust the spindle to 4-5 revolutions per minute, feed the short material, and connect the copper rod after the product is extruded normally. Control spindle speed between 5.5~10rpm per minute, mold cavity temperature 4...

Abstract

The invention discloses a process for producing an enameled wire for a compressor. The process comprises the following steps of: an extrusion procedure: extruding an oxygen-free copper rod produced by the continuous casting and rolling process to obtain a bare copper wire; cleaning the bare copper wire, removing oil stain and attachments on the surface of the bare copper wire to achieve the surface cleanness required by a painting procedure; and a painting and baking procedure: painting the bare copper wire in a manner of supplying paint by a metering pump and painting by a plurality of moulds, wherein the primer is polyesterimide and the finish paint is polyamideimide composite insulation paint; carrying out secondary baking by using hot air circulation and catalytic combustion, and sufficiently combusting solvent in the insulation paint; and gathering the wire to obtain the enameled wire for a compressor. The process disclosed by the invention has simple process, small investment and short time for refitting the current equipment; and the produced enameled wire can fully meet the requirements of the R134a compressor.

Description

technical field [0001] The invention relates to an enameled wire for a compressor, in particular to a production process for an enameled wire for an R134a compressor. Background technique [0002] At present, most of the compressors used for refrigeration appliances such as refrigerators and freezers use R12 as the refrigerant, which belongs to CFCs (Freon series) substances. Due to the extensive use of R12, it causes damage to the atmospheric ozone layer and produces a greenhouse effect, which in turn endangers the survival of human beings. Therefore, the International Convention Organization concluded the "Montreal Convention", which requires countries to gradually reduce and eventually stop the production and use of R12. At present, manufacturing companies in most countries and regions have chosen R134a and hydrocarbons as substitutes for R12. Although hydrocarbons do not cause environmental pollution, the refrigeration effect is not ideal, and the safety protection requi...
