155-grade polyester enameled copper wire production process

Abstract

The invention relates to a 155-grade polyester enameled copper wire production process. A painting device comprises a rack and a painting pool arranged on the rack, a sliding groove is formed at the upper end of the rack and along the width direction of the rack and penetrates through the rack, and a sliding base slidably inserted into the sliding groove is arranged at the lower end of the painting pool. A control assembly for controlling the sliding base to move is arranged on the rack, and the sliding base is inserted into the sliding groove in a sliding mode. According to the present invention, the detachable installation of the painting pool on the rack is achieved, during the actual paint changing process, the painting pool is directly detached from the rack, then a new painting poolis installed on the rack, and the paint does not need to be changed in the painting pool, so that the paint utilization rate is increased, and the wire painting machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of enameled wires, in particular to a production process of 155 grade polyester enameled copper wires. Background technique [0002] Enameled wire 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. [0003] The patent of the existing notification number CN107240464B discloses a production process of a flat enamelled copper wire with a large aspect ratio, and the steps are roughly as follows: A. laying out and straightening; B. extruding round wire; C. extruding flat wire Ⅰ; D. Extruded flat wire Ⅱ; E. Extruded flat wire Ⅲ; F. Cooling; G. Ultrasonic cleaning; H. Annealing; I. Cleaning and drying; J. Paint baking; K. Cooling traction Wire. [0004] Among them, in step J, the patent disclosed as CN204375500U discloses an enamelled copper wire painting device, which includes a bottom plate, wh...

Problems solved by technology

[0006] When it is necessary to set a paint layer of different materials on the outside of the copper wire, it is necessary to release and clean the paint in the paint tank, and then send the required paint into the paint tank, resulting in waste of paint and loss of copper wire. The preparation time before painting is long, which affects the painting efficiency of copper wire
