Abstract

The invention relates to electrical engineering and can be used in the manufacture of transformers and chokes. The purpose of the invention is to simplify the technology. In the manufacture of chokes, the surfaces of the magnetic core preform are activated, cut into pieces at the junction, paint the magnetic core surfaces by dipping a coating solution (except for the junction surfaces), attach a bonding agent to the junction surfaces, collect parts of the magnetic core with a coil, and glue them together joint while compressing and heating.

Description

I1 acquisitions are electrical and can be used in the manufacture of transformers and drosses, for example, ballast drossejiLJii and gas discharge lamps.

The purpose of the invention is to simplify

The method is custom; this is followed in the next way.

The billet of the twisted magnetic core is degreased, the active 1C {its surface is made, the blank is cut into two parts and painted by auto-deposition of the magnetic core surface, while the non-activated interface surfaces are not painted. Then, the surfaces of the STIS ({lnos t adhesive agent, collected by the mouth of the magnetic conductors with an aperture cup and put them in place of the junction with simultaneous compression and heating.

Example. The workpiece of the twisted magnetic core is degreased in an alkaline detergent solution of the following composition, g / l:

Caustic soda 10-15

Tririat phosphate 10-15

Metasilicate sodium 5-10

Sintanol APS 12

Phenoxol VIS-15 2

18-25 ° C and phosphate in a zinc-phosphate solution of the following composition, g / l: Monotone monophosphate 28-36 Nitrous acid zinc 42-58 Orthophosphoric acid 9-14 Phosphate time 7-10 million, solution temperature 85-90 C.

After washing in hot industrial water, the preform of the magnetic core is dried with compressed air.

After activating the surface, the preform magnetopropod is cut into two halves, which are then dyed by the auto-deposition method, o into a solution of an autophoretic material, for example VD-KCh-0178, at 18–25 ° C for 30–40 s, at a material pH of 1.1–2 ,one. The composition is adjusted to the required RP value with a 10% orthophosphoric acid solution. The deactivated npi interface dipping into autophoresis- Hbrii material remains unpainted.

Next, the halves of the magnetic conductor are floated in cold water, blown with ropHiniM with air and dried at 135-145 ° C for 20-25 minutes.

The painted halves of the magnetic core with the adhesive material carried at the joint surface are assembled with the compressed coil while compressing and heating. As a gluer

material use premix PSK-5RM according to TU 6-11-544-82. Coloring of chokes can also be done assembled from katui coy.

The invention allows to simplify the technology due to the fact that there is no need to protect the interface surface in the process of painting the surfaces of the magnetic conductor, since the painting by the method of auto-deposition of the coating is carried out only on the activated surfaces.
