Extrusion process for manufacturing enameled wires

Abstract

The invention discloses an extrusion process for manufacturing an enameled wire. The extrusion process for manufacturing the enameled wire comprises the following steps: selecting raw materials, wherein a trial-manufactured conductor is a copper round wire with the nominal diameter of 1.00, the thickness of a PEI insulating layer is 0.07-0.09 mm, the PEI insulating layer is extruded on the copperround wire through an SJ-45 plastic extruder, then a polyethylene layer is extruded, and a nylon sheath is extruded; cooling, blow-drying, inspecting, winding and arranging the PEI insulating layer, the polyethylene and the extruded nylon sheath which are prepared in the above steps in sequence; and finally performing metering, packaging and warehousing. According to the extrusion process for manufacturing the enameled wire, the extruded product mainly uses a sub high-frequency electronic transformer, a partition plate, interlayer adhesive tape and insulation adhesive tape in the transformer can be omitted, the production cost is reduced, the size and the weight of the transformer are reduced, lightness, thinness and shortness are realized, the use of an organic coating in the production and application process of a conventional insulation system can be reduced and avoided, and the insulation system is an environment-friendly green material.

Description

technical field [0001] The invention relates to the field of enameled wire preparation, in particular to an extrusion process for manufacturing enameled wire. Background technique [0002] Enameled wire is the main raw material of products such as motors, electrical appliances and household appliances. Especially in recent years, the electric power industry has achieved sustained and rapid growth, and the rapid development of household appliances has brought a wider field of application of enameled wire, followed by Higher requirements are put forward for enameled wire. For this reason, the product structure adjustment of enameled wire is inevitable, and the raw materials (copper, lacquer), enamelling process, process equipment and detection methods that are matched with it are also urgently needed to be developed and researched; [0003] At present, there are more than a thousand enameled wire manufacturers in my country, and the annual production capacity has exceeded 250...

Problems solved by technology

[0004] The enameled wire produced by the traditional preparation process cannot be light, thin and short, and cannot reduce and avoid the use of organic coatings in the production and application of conventional insulation systems. Therefore, we propose an extrusion process for manufacturing enameled wire
