Enamelled rectangular wire painting assembling die and enamelled rectangular wire painting method

Abstract

The invention relates to an enamelled rectangular wire painting assembling die and an enamelled rectangular wire painting method, and belongs to the technical field of enamelled rectangular wire painting tool dies of transformers. According to the technical scheme, the enamelled rectangular wire painting assembling die comprises fixing adjusting rods (5), rolling sleeves (2) and bolts (6), the rolling sleeves are arranged on the axes of the corresponding fixing adjusting rods through the bolts, the surface of each rolling sleeve is provided with a thread, the rolling sleeves rotate on the fixing adjusting rods, two adjacent dies are connected through the fixing adjusting rods, the rolling sleeves on the fixing adjusting rods form the four edges of a rectangle, the fixing adjusting rods are arranged on a spring ring (4), a channel of a conductor is a rectangular channel of the assembling die after stretching, the conductor (3) sequentially penetrates through the rectangular channel and the center of the spring ring, and the conductor is painted through the threads on the surfaces of the rolling sleeves. The enamelled rectangular wire painting assembling die and the enamelled rectangular wire painting method have the advantages that uniformity of film painting of enamelled rectangular wires is improved, the performance of the enamelled rectangular wires is optimized, production efficiency is improved, raw materials are saved and production cost is lowered.

Description

technical field [0001] The invention relates to an enamelled flat wire painting combination mold and a painting method, and belongs to the technical field of transformer enamelled flat wire painting tooling molds. Background technique [0002] At present, the production of enamelled flat wire in my country is mainly based on fixed molds for painting. The disadvantages of this process are: the size of the painting mold is fixed, and the requirements for the conductor size are relatively high; at the same time, because the fixed mold is changing the wire gauge, adjusting the paint When the film thickness needs to be replaced, the mold must be stopped. Because the furnace body of the vertical enameled furnace is relatively high and there are many passes, the line of a furnace should range from 470 meters to 540 meters. Therefore, the waste of waste lines for parking and hanging molds is relatively high. At the same time, due to the high temperature in the furnace, which is abou...

[0002] At present, the production of enamelled flat wire in my country is mainly based on fixed molds for painting. The disadvantages of this process are: the size of the painting mold is fixed, and the requirements for the conductor size are relatively high; at the same time, because the fixed mold is changing the wire gauge, adjusting the paint When the thickness of the film needs to be replaced, it is necessary to stop the machine

Because the furnace body of the vertical enameled furnace is relatively high and there are many passes, the line of a furnace should range from 470 meters to 540 meters. Therefore, the waste of waste lines for parking and hanging molds is relatively high

At the same time, due to the high temperature in the furnace, which is about 400 degrees, it takes a long time to stop, hang the mold, start the car, etc., and the furnace temperature can be reduced to about 80 degrees, which will cause a large loss of heat in the furnace

When changing the mold, more than 2 people need to cooperate to complete it, and the working time is about 3 hours, which is time-consuming and laborious

In addition, it also has a great impact on product performance: when the conductor is not perpendicular to the mold, the amount of paint on the four surfaces of the bare wire will be uneven, causing the paint film to be eccentric; although the performance of the enamelled flat wire meets the user's requirements, the Line performance is not optimal
