An Improved Movable Painting Die for Enameled Wire

Abstract

The invention discloses an improved enameled-wire movable painting mould. The mould comprises a wire drawing apparatus, an annealing apparatus, the painting mould, a magnetic mould and a paint providing apparatus. The painting mould comprises a painting mould sleeve and a painting mould core. The painting mould sleeve comprises a first substrate, a second substrate and an adjusting handle. Two sides of the first substrate and two sides of the second substrate are vertically and detachably connected so as to form a third cavity. The first substrate is provided with an adjusting hole. The adjusting handle is penetrated into the second substrate and enters into the third cavity so as to fix the painting mould core. The painting mould core is fixed in the painting mould sleeve. A sizing cavityis formed between the painting mould sleeve and the painting mould core. Inner cavities of the third cavity, the sizing cavity and the painting mould core are connected. One side of the painting mould sleeve is provided with a paint inlet. The mould sleeve in the painting mould can be movably adjusted so that the painting mould can be suitable for painting of different specifications of leads anda rejection rate of a bare copper wire can be greatly reduced. Materials are saved, dismounting is convenient, worker labor intensity is effectively reduced and production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of enameled wire painting, in particular to an improved movable enameled wire painting mold. Background technique [0002] With the development of enameled wire painting technology in the world, mold method painting has been more and more widely used and developed, especially in recent years, the birth of various enamelling machines with high D value has made mold method painting technology obtain more Broad development and application; mold method painting technology has the incomparable advantages of low cost, high efficiency, stable quality and other painting methods, and has been favored by major enameled wire factories at home and abroad. Paint technology, expand the scope of mold paint wire diameter, and strive to find new economic growth points for enterprises. [0003] The traditional painting process of bare wire generally includes felt painting and mold painting. Among them, the felt painting has ...

Problems solved by technology

[0003] The traditional painting process of bare wire generally includes felt painting and mold painting. Among them, the felt painting has the advantages of convenient operation and convenient exchange of wire gauge, but the felt painting requires relatively high viscosity of the paint, and the paint The film is not easy to control, and the felt needs to be replaced frequently, and the insulating paint is easily polluted, which affects the insulation performance of the bare wire; while the mold method uses a fixed mold, which has the following defects: each specification of the bare wire has to go through more than ten Each painting and baking process needs to be equipped with a corresponding painting mold, and the corresponding molds for different specifications and sizes of bare wires are different, so the reuse rate of molds is low, and the number of molds required in actual production Large size, high production cost; when processing bare wires of different specifications, it is necessary to replace the corresponding painted molds. Generally, the bare copper wires are cut off at each mold, and then the corresponding molds are replaced, and then the cut bare copper wires are welded connection, the replacement of the mold is cumbersome and complicated, the labor intensity of the workers is high, and the efficiency is low, and the bare copper wire is cut off and then welded when the mold is replaced, which directly leads to the scrapping of the bare copper wire, resulting in a large amount of waste of the bare copper wire. Therefore, it is necessary to set up a A movable paint mold is suitable for processing bare wires of different specifications
