[0002] Enameled wire is a main variety of winding wire. Winding wire is a conductive metal wire with an insulating layer. It is used to wind the coil or winding of electrical products. It is composed of two parts: conductor and insulating layer. After the bare wire is softened by annealing, After many times of painting and baking, it is not easy to produce products that meet both standard requirements and customer requirements, because it is affected by factors such as raw material quality, process parameters, production equipment, and the environment. Therefore, various The quality characteristics of enameled wires are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. During processing, in order to strengthen flat copper wires, it usually needs to go through various processes. The processes are: wire and straighten; extrude to make round wire; extrude to make flat wire; ultrasonic cleaning; soften; cool; wash and dry; 7 times; the finished high-strength precision flat enamelled copper wire can be obtained by pulling the wire, but the general copper wire extrusion equipment can only be extruded once, and can process copper wires of different diameters. Both need to be cooled, and the existing cooling and extrusion are carried out on different equipment, which affects the efficiency. Therefore, we propose an extrusion strengthening equipment for high-strength flat copper wire to solve the above-mentioned problems
