Description

Painting mold support capable of flexibly adjusting levelness

Technical Field

The utility model belongs to the technical field of enameled wire painting dies, and particularly relates to a painting die support capable of flexibly adjusting levelness.

Background

The painting mold used in the enamelled wire painting process is used by being fixed to a mold support installed between a painting roller and a baking oven of an enamelling machine.

The metal conductor wire passes through the groove on the rotating painting roller, paint with certain viscosity and solid content attached in the groove is adhered to the surface of the metal conductor, the metal conductor attached with paint liquid passes through the diamond inner hole in the painting mold, and the excessive paint liquid exceeding the diameter of the inner hole is scraped off from the surface of the metal conductor and flows back to the paint liquid collecting device. The metal conductor which passes through the painting mould and is adhered with paint liquid with certain thickness enters a baking oven, and the paint liquid on the surface of the conductor is subjected to cross-linking and curing at high temperature in the baking oven to form an insulating paint film.

The metallic conductor with the thin paint film passes through the roller again, adheres a new layer of paint liquid, and then passes through the next painting die, repeating the previous process. After N times of coating, paint scraping and baking, the required total thickness of the paint film is achieved, and the painting production process is completed.

In the painting process, the center of the cross section of the moving metal conductor is coincided with the center of the cross section of the diamond inner hole of the painting mold in each pass, so that the finally formed paint film is uniformly adhered to the surface of the conductor, and the thickness of the paint film is consistent. Thereby ensuring that all indexes of the insulating layer are consistent.

If the center of the cross section of the metal conductor is not concentric with the cross section of the diamond inner hole in the painting mold, the coating of the insulating layer is not concentric, and the metal conductor is rubbed to the inner side surface of the diamond inner hole of the painting mold in severe cases, so that the painting mold is worn quickly. Fig. 7 and 8 are schematic views illustrating the formation of a uniform insulating layer and a non-uniform insulating layer, respectively.

According to the traditional large-aperture (more than 0.200 mm) painting mold, a used mold support is relatively extensive in technical management, multiple sets of painting molds are arranged on the same mold support, left-right and front-back horizontal adjustment of a single set of painting mold cannot be realized, local fine adjustment cannot be carried out due to unreasonable installation positions of one or more sets of painting molds caused by the fact that a base is not horizontal or deformed, and various abnormal painting problems such as uneven painting, paint film surface scratch, quick wear of the painting molds and the like caused by the fact that the central axis of the painting mold is not coincident with the central axis of a metal conductor often occur.

The requirements on the tolerance control precision of the outer diameter of a large-size enameled wire paint film of more than 0.20mm are low, and the requirements on the consistency of the physical, chemical and electrical properties of the paint film are not high, so that the paint film can meet the use requirements, but cannot meet the requirements on the consistency and surface quality of a fine enameled wire paint film with the diameter of less than 0.10 mm.
