Abstract

The invention relates to a high-speed continuous large-capacity take-up production process for a small-sized enameled wire. The process comprises the following steps: step S1: coarse wire drawing; step S2: intermediate wire drawing and annealing; step S3: coating wire drawing; step S4: coating; in the step S4, the core of a painting mold used for applying the insulating varnish by the painting mold is made of a polycrystalline material; in the step S4, the taper of the leading-out terminal of the painting mold is 7.5 degrees; in the step S4, a baking traction wheel used for baking and a pre-painting branching large guide wheel corresponding to the baking traction wheel are cones, and the cones have a taper of 3.39 degrees. The high-speed continuous large-capacity take-up production processhas the advantage that the mold core of the paint mold is made of the polycrystalline material, so that wear resistance is realized; the taper of the leading-out terminal of the painting mold is 7.5degrees, 3.75-degree swinging is formed between a mold base and the leading-out terminal, which is favorable for an enameled wire to self-center, and reduces the probability of wire disconnection; andthe taper of the baking traction wheel and the pre-painting branching large guide wheel is 3.39 degrees, so that the tension of the enameled wire is constant in the oven, and the doubling and chaoticwires are avoided.

Description

technical field

[0001] The invention relates to the technical field of enameled wires, in particular to a high-speed continuous large-capacity winding production process for small-sized enameled wires. Background technique

[0002] Small-sized enameled wire refers to enameled wire with a conductor specification of Φ0.10mm to Φ0.30mm. In order to improve production efficiency, customers often use production equipment with a high degree of automation, requiring enameled wire: 1) large capacity for take-up and release, and a single-axis enameled wire weight of at least 60-90kg; 2) high product performance consistency, so enameled wire manufacturers must It is produced by the continuous drawing and packaging equipment integrating continuous wire drawing and coating, and adopts the mold coating process to achieve the requirements of uniform thickness of enameled wire paint film, good consistency of conductor and outer diameter; at the same time, with the increase of environmental...
