Embodiment 1

[0042] A method for manufacturing a high temperature resistant enameled wire, comprising the following steps:

[0043] A: To make the inner core, first select the copper wire, detect the burr on the outer surface of the copper wire and remove the burr. When inspecting the outer surface of the copper wire, ensure that the copper wire has no oxidation and no cracks on the surface. Both ends of the copper wire are fixed, and the copper wire is straightened by stretching equipment. The copper wire is selected as pure copper with a high conductivity of more than 99.5%;

[0044] B: wire drawing, the copper wire is drawn by drawing equipment, the number of drawing is 7 times, and the copper wire is drawn to the required diameter;

[0045] C: Cleaning, clean the oil on the surface of the copper wire to keep the copper wire flat, clean the surface of the copper wire with clean water, and filter and recycle the waste water after use;

[0046] D: Annealing, place the copper wire in the ...

Abstract

The invention discloses a manufacturing method of a high-temperature-resistant enameled wire, and relates to the related technical field of enameled wire production, which comprises the following steps: step A, manufacturing an inner core; b, wire drawing; step C, cleaning; step D, annealing; e, cooling is conducted; f, paint spraying is conducted; and G, lubricating and taking up. The invention is advantageous in that the production is time-saving and labor-saving, detection of copper wires, the use stability of the enameled wire after production is stronger; post annealing, the annealed copper wire is cooled through the drying furnace; the temperature of the copper wire is kept at 150-230 DEG C; the subsequent insulation paint spraying and copper wire connection is more stable; the stability of the overall high-temperature resistance of the produced enameled wire is further improved; the copper wire spraying device is simple in structure, longer in service life and higher in stability, insulating paint can be sprayed to copper wires passing through the middles of the first spraying parts and the second spraying parts through cooperation of the first spraying parts and the secondspraying parts, and inner-layer paint and outer-layer paint of the copper wires can be sprayed through the multiple sets of first spraying parts and second spraying parts correspondingly.

Description

technical field [0001] The invention relates to the technical field related to the production of enameled wires, in particular to a method for manufacturing high-temperature resistant enameled wires. Background technique [0002] Enameled wire is the most representative product in electronic wire. Enameled wire is a main variety of winding wire. It is composed of two parts: conductor and insulating layer. It is not easy to produce products that meet both standard requirements and customer requirements. [0003] Affected by environmental factors, the quality characteristics of various enameled wires are different, but they all have good mechanical and chemical properties. However, in high-temperature environments, the current enameled wires have a short service life and poor high-temperature resistance. The medium loss is serious, the use is not stable enough, and the normal use of the wire is easily affected during use. [0004] Therefore, it is necessary to propose a manu...
