Abstract

The use of electrical engineering, instrumentation technology, manufacturing ring coils The essence of the invention is laying the wire from two supply coils and through two pulse mechanisms, thus connecting and fix the ends of the wire from both coils on the core, and when rewinding the spool is rotated in opposite directions 2 or 3

Description

The invention relates to the technology of manufacturing electrical machines and apparatus, in particular for the manufacture of ring transformers and chokes, and can be used in the electrical, instrument-making industry

There is a method of laying the winding in the closed grooves of the magnetic circuit, including the simultaneous layout of the turns of the two bobbin mechanisms, reciprocating movement of the wire through the hole of the magnetic circuit

However, the laying of the winding by this method is not sufficiently productive, as it requires a wire of decreasing length through the holes of the magnetic conductor to sweep the wire stock in proportion to the number of turns wound on the magnet wire.

A known method of manufacturing ring coils, comprising laying the wire stock on the ring core using a two-barrel mechanism of the ring winder

The disadvantage of this method is that it does not allow simultaneous winding of the ring coil by two bobbin mechanisms.

The closest to the present invention is a method for manufacturing ring coils, which includes laying a margin of wire on the ring core from the supply coil through the bobbin mechanism of the ring coil

The disadvantage of the prototype is the need to periodically flip the wire output through the winding plane during the axial rotation of the ring core

The aim of the invention is to increase labor productivity by dividing the magnetized stock of wire into two parts.

Compared with the prototype, the laying of the wire on the ring core is carried out from two feed coils and through two bobbin mechanisms rotated in opposite directions, having previously connected and fastened the ends of the wire from both coils to the core

The implementation of the method of manufacturing the ring coils is carried out using an annular winding machine containing two bobbin mechanisms. 1 Mechanism

It contains concentric spools 2 and 3, each of which consists of two coaxial rings 4-5 and 6-7 with removable sectors (not shown). The ends of the rings 4 and 6 are made with annular protrusions 8 and 9 and together with the ends of the rings 5 and 7 form a groove 10 and

I1 variable cross-section for laying wires .12. Rings 4 and 6 are fixed on the body (not shown) of the mechanism 1 with a constant clearance between the ends of the rings 4 and 6 and connected to the drive, which ensures the rotation of the ring 4 clockwise, and the rings 6 - counterclockwise. The ring 5 is spring-loaded axially relative to the body and the ring 6.

The method of manufacturing the ring coils is carried out as follows.

Preliminary, on the open winding machine, they sweep from one supply coil 13 to an empty supply coil 14 half of the supply of wire 12 of the winding. Coils 13 and 14 are installed in a coil holder (not shown). The ring core 15 is secured in an axial rotation mechanism (not shown) of the machine between the spools 2 and 3 with detachable sectors removed from them. The branches 16 and 17 of the wire 12 from the coils 13 and 14 pass between the pairs of rings 4-5 and 6-7 spools 2-3 and set removable sectors on the rings 4-7 so that they acquire a closed circular shape. The midpoint 18 of the wire 12 is fixed to the ring core. Pass the branch 16 of the wire 12 over the groove 10, through the roller 19, and the branch

17 wires 12 - over the groove 11 and through the roller 20 and remove the slack of the branches 16-17 by winding the wire 12 on the coils 13 and 14.

The machine drive is driven into rotation around section 21 of the core 15, spool 2 clockwise and spool 3 counterclockwise. When coiling the wire 12 from the coils 13-14 with each turn of the spools

2-3, two turns of winding are laid on the core 15, and the supply of wire 12 on each spool 2-3 in the grooves 10-11 is increased by a loop. With the passage of the wire 12 coiled onto the core 15 between the projections

8-9, the rings 4 and 6, at the vanishing points of the wire 12, spring out axially from the rings 5 and 7 by an amount equal to the diameter of the wire 12.

After coiling the wire from the coil

14, the end of the wire 12 is cut off from the supply coil 13 in the area between the coil 13 and the roller 19, and the winding of the wire 12 formed in the grooves 10 and 11 continues 2-3. At the end of the winding

decorate the lead ends of the winding and remove the coil from the machine.
