Winding wire manufacturing technology

Abstract

The invention relates to a manufacturing process of a winding wire, characterized in that the process comprises the steps that: the element billet wire of an electrolytic copper is put into a vacuum non-oxygen annealing furnace for vacuum annealing; the annealed element billet wire is flatted by a flattening roll; the material flattened in the second step is put into the vacuum non-oxygen annealing furnace for the second time for vacuum annealing ; the material annealed in the third step is stretched by a drawbench; the material stretched in the fourth step is put into the vacuum non-oxygen annealing furnace for the third time for vacuum annealing; the material annealed in the fifth step is stretched by the drawbench for the second time for forming a 0.55mm thick winding wire; and finallythe winding wire is put into the vacuum non-oxygen annealing furnace for the fourth time for vacuum annealing. The manufacturing process can produce 0.55mm winding wire, which reaches the localizationdegree.

Description

Technical field [0001] The invention relates to a manufacturing process of a winding wire, which can be used to manufacture a generator of an automobile, and belongs to the technical field of manufacturing processes. Background technique [0002] With the increase in the degree of localization in the automobile industry, the materials required for the manufacture of automobile parts are close to foreign materials. Foreign automobile generators are small and light. The reason is that the thickness of the winding wires for certain automobile generators is only 0.55mm. At present, the minimum national standard for the production of automobile generator winding wires in China is 0.8mm. Due to the insufficient toughness of the material, if the traditional rolling process is used to roll 0.55mm thick winding wires, the product performance cannot meet the technical requirements. . Summary of the invention [0003] The purpose of the present invention is to provide a manufacturing proces...

Problems solved by technology

[0002] With the enhancement of the localization of the automobile industry, the materials for manufacturing automobile parts are required to be close to foreign materials, and foreign automobile generators are small and light. At present, the minimum national standard for the domestic production and manufacture of automotive generator winding wires is 0.8mm. Due to the insufficient toughness of the material, if the traditional rolling process is used to roll out winding wires with a thickness of 0.55mm, the product performance cannot meet the technical requirements.
