Description

one

The invention relates to process equipment for manufacturing electric coils and can be used in the radio electronic and instrument-making industry.

A universal tensioning device is known to the machines for winding electric coils, ensuring that it is wound in an axial way with a rotary connection, to her coils 1.Y

However, this device does not rewind the wire and, therefore, does not eliminate the overlap of turns on the coil.

It is also known a device for axially winding 55 wires containing its bar, guided by a loop, its ring fixed on the bar, the base, the donating coil, mounted on the base for rotation, the drive of the donating coil, and 20 a balloon-limiting device, in the case of which is installed with the possibility of - the available movement of the pin entering the groove made on the guide cone 2. Such a device is the closest to the invention in its technical essence and the result achieved. However, the design of the known device does not provide for the rewinding of the wire to the giving coil of its equal

dimensional layout along the entire length of this coil. In this device, during rewinding, the entire wire accumulates in the upper part of the reeling roll, which can lead to an overlap of the coils, as a result of which wire breakage can occur when winding it from the reeling coil.

The purpose of the invention is to eliminate overlaps when rewinding the wire.

This is achieved by the fact that in the Axial Cable Winder, which contains a mechanism for fixing the returning roll, a rotational drive of the return coil and guide elements for the wire, a mechanism for fixing the return coil is made in the form of a hinged bracket on which the eccentric is attached. with shtanga.

FIG. 1 depicts an axial winder; in fig. 2 - brackets in the position when rewinding the wire to the giving coil with the layout in direction from “a to“ b on the giving coil; in fig. 3 - brackets in position when laying the wires from “b to“ a.

The device comprises a bar 1 with a guide ring 2 and a clip 3, on which a bracket 4 is hinged.

The base 5. On the base, there is a retracting coil 6 with a wire 7, a rewind electric motor 8, and an eccentric 9 in contact with the rod when the bracket is rotated.

The device works as follows.

In the event of an overlap on the product, violation of the winding pitch, loop, etc., the operator turns off the winding machine and turns the bracket 4 together with the sending coil 6 and the electric motor 8 up to the stop of the eccentric 9 with the rod 1, setting the initial position and direction of the eccentric rotation depending on from the required direction of the layout of the bridge 7 when rewinding it to the outgoing coil 6 (see Fig. 2 and 3).

After that, the winding machine switches back and the electric motor 8 is turned on at the same time, which turns on the distributing roller 6. The eccentric 9 is manually rotated around its axis, as a result of which the angle of the secondary coil 6 and the actuator 7 is tilted to the original roller. 6 with the layout but its entire length.

Removing the overlap on the product, the operator turns on the winding machine and the electric motor 8. Then the bracket 4 with the coil 6 and the electric motor 8 returns to its original position (see Fig. 1), in which the electric coils are further wound when axially winding the wire 7 from the fixed source coils 6.

The co-structuring of the device for axial winding of wires, in which the locking mechanism of the sending coil is made in the form of a hinged bracket mounted on the rod, on which the eccentric is in contact with the rod, allows to rewind the wire to the giving coil with a lay-out of turns on it evenly.
