A kind of enameled wire production process

Abstract

The invention belongs to the technical field of enamelled wire production, in particular to an enameled wire production process. The process comprises a blank preparation step, a wire drawing step, acleaning step, an annealing step, a cooling step, a painting and baking step, a lubricating step and a take-up step. In the take-up step, the tensioning control assembly comprises a horizontal slidingguide rail, a guide block, a swing wheel and a follow-up rotating rod; A spiral groove is arranged at the body of the follower lever around the axis of the follower lever, the guide block extends toward the spiral groove and is provided with a shift arm, and an extension of the shift arm extends into the spiral groove cavity; A rotary switch for monitoring the magnitude of rotation of the follower lever is arranged at the lever end of the follower lever. The enameled wire produced by the production process has the advantages of good uniformity of the paint film, high breakdown resistance, reasonable process steps and high processing efficiency, and can effectively improve the production efficiency and the finished product quality of the enameled wire.

Description

technical field [0001] The invention belongs to the technical field of enameled wire production, and in particular relates to an enameled wire production process. Background technique [0002] Enameled wire is the most representative product in electronic wire. Enameled wire is a main variety of winding wire, which is composed of conductor and insulating layer. It is formed by annealing and softening the wire, and then painting and baking for 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 properties four major properties. The enameled wire has to undergo multiple heat treatments and other processes during the produ...

Problems solved by technology

The above-mentioned structure has the following problems: On the one hand, due to the large impact force when the ball screw moves, after a long period of use, it is easy to cause work wear and thus reduce its service life, and the gap caused by wear will increase the operating noise of the machine sharply

On the other hand, since the proximity switch is fixed on the guide wheel seat and moves with the guide wheel seat, not only the proximity switch needs to be connected to the external wire, but the external wire will be rubbed and worn with the frequent movement of the guide wheel seat or even the wire body will be broken. At the same time, because the wire base is inevitably affected by the ball screw during work, there is a vibration problem, and the proximity switch is fixed on the wire base, which makes the proximity switch accompanied by vibration, resulting in poor sensitivity of the proximity switch. The failure rate increases, and the service life and work reliability decrease sharply
