Abstract
Description
technical field
[0001] The invention relates to the field of enameled wire production, in particular to a wire-drawing device and a wire-drawing method for ultra-fine wires used in enameled wire production. Background technique
[0002] Enameled wire refers to a metal wire that uses insulating varnish as an insulating coating and is used to wind electromagnetic coils, also known as electromagnetic wire. It is a main variety of winding wire, which is composed of conductor and insulating layer. After the bare wire is annealed and softened, it is painted and baked many times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and the environment. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, thermal properti...
