The invention relates to manufacturing equipment for manufacturing electric coils and can be used in winding machines in the electrical, electronic and other industries.

A known machine for winding electric coils, containing a faceplate mounted in an axially movable quill, is fitted on the faceplate a leash on which the guide and unfolding rollers with a movement limiter m are fixed. However, the limiter is attached to the folding roller at the side and prevents the wire from falling out of the folding roller groove, does not remove excessive cable thread during winding, which leads to a decrease in the quality of winding, i.e. it can be an overlap of turn on a turn.

The aim of the invention is to improve the quality of manufactured products by eliminating the overlapping of the turns in the layer.

The goal is achieved by the fact that in the device for winding electric coils containing a lead mounted on a faceplate on which the guide and folding rollers are located, and a wire movement limiter, the latter is made in the form of two plates between which the bearing is installed, and is located under the folding roller.

FIG. 1 shows the proposed device, a general view; in fig. 2 view A in FIG. one; in fig. 3 — wire movement restrictor, general view; in fig. 4 shows a multi-spindle unit with several rotating faceplates, a general view.

The device (Fig. 1) contains a leash 1 mounted on the faceplate, on which a guide 2 and folding 3 rollers are fixed with a limiter 4 of wire displacement, located 3888

Placed under the folding roller 3, Limiter 4 (Figs. 2 and 3) has clamping cheeks 5 forming the groove 6 located along the wire feed direction 7. The groove 6 has a directional bearing 8. The winding machine can be equipped with several rotating faceplates spindle unit, while

10 axes of the leads of the faceplates and the longitudinal axis of the spindle unit are located in the same plane (Fig. 4). The mandrel 9 serves to secure the frame of the electric coil. The spindle 15 unit is kinematically coupled to the actuator 10.

The device works as follows.

Pass the wire 7 through the guide 2, folding the 3 rollers and the stop 4, and then fix the wire on the mandrel 9. Then the mandrel 9, on which the frame of the electric coil is fixed, is fed to the position

25 winding. The actuator 10 is turned on, and through a kinematic filter, the rotational movement is not given to the faceplate and together with it the leash 1, the guide 2 and the folding 3 rollers. Wire 7

30 is wound on the mandrel 9. With the help of the stopper 4, along the channel 6 of which a wire 7 is laid through the guide bearing 8 along the direction of its supply, the wire 7 is wound on the mandrel 9 in exactly the same way, since this prevents its deviation to one side or the other. the slipping of the wire along the guide bearing 8 is also avoided.

e. The efficiency of application consists in increasing the quality of the winding by reducing the vibrations of the wire, since its deviations to one side or the other are limited by the groove of the limiting bodies, and also by eliminating

wire slippage along the guide bearing. All this provides a clear wire length during winding and eliminates the overlap of the turn on the turn.
