Description

FIELD OF THE INVENTION The invention relates to devices for a series winding of products such as filaments, in particular, they can be used for winding thin-wire high-voltage disk electric coils of large diameter with a winding thickness significantly exceeding its width.

In the proposed device for winding coils containing a mandrel with a rotation drive, a leash device of a leash and a driver, a tension device, a transmitting roller is introduced between the leash device and the mandrel, the forming surface of which is in contact with the forming surface of the mandrel, the axis of the roller is fixed on the swivel bracket . The diameter of the roller (D) is determined from the ratio:

2H + B D S A-C + B where I is the thickness of the winding.

In - the diameter of the axis of the transmitting roller ;.

A-t maximum diameter of the coil wound on the machine;

C is the inner diameter of the coil.

Thanks to the use of a transfer roller with the indicated ratios, the coils from the overlying layers are prevented from falling into the underlying layers, the insulation of the wire itself operates under lighter voltage conditions, which makes it possible to increase the voltage by one turn in devices using electric coils, reduce the number of turns in the coil, reduce wire consumption, reduce the dimensions of the device.

A structural diagram of a device for winding coils is shown in the drawing.

The device for winding coils includes a mandrel 1 with a rotation drive for winding coils 2, a lead 3, a driver A of wire 5, a transmitting roller 6 mounted on an arm 7, rotating on an axis 8. The arm 7 together with the roller b can rotate about an axis 9. Thickness the transfer roller 5 is equal to the width of the winding coil 2. The forming surface 10 of the transfer roller 6 is constantly in contact with the forming surface 11 of the mandrel 1 and the winding coils of the coil 2 by means of a clamping device 12 ..

The tensioning device 13 provides a constant tension of the wire 5 when it is removed from the reel 14.

The device operates as follows. After filling the wire 5 into the driver 4 of the wire, the mandrel 1, the transfer roller 6 enveloping its wire 5 is inserted into the slot of the mandrel 1 until the forming surfaces 10 and 11 of the roller 5 come in contact with the mandrel 1, The lead 3 is moved to one of the extreme positions, the mandrel rotation drive is turned on 1, the movement of the leash 3 is coordinated using the mechanism of coordination with the rotation of the mandrel 1. The leash 3, after winding one layer of wire 5 of the coil 2, moves to another extreme position. Then the leash 3 moves in the opposite direction, the next layer of wire is wound, etc. The wire 5, with the help of the driver 4, is laid on the transfer roller 6 with an offset equal to the diameter of the wire 5, by one revolution of the mandrel 1. Rotating, the transmitting roller b, due to the constant clamping to the mandrel 1 and the constant tension of the wire 5 device tension ha, will transfer wire 5 to mandrel 1 with a given driver 4 wires 5

in a strictly oriented place on the mandrel 1.

The minimum diameter of the transfer roller b is determined by the thickness of the winding of the coil 2 and the diameter of the axis 8 on which it rotates. It is impractical to make a smaller diameter of the transfer roller 6 due to the fact that its forming surface 10 during the initial winding period cannot be in contact with the forming surface 11 of the mandrel 1, and the wire 5 will not be orientedly laid by the transfer roller b in the layers of the coil 2.

The maximum diameter of the transfer roller b is determined by the maximum diameter of the coil wound on the machine and the diameter of the axis 8 on which it rotates, but the coils wound in the mandrels must have a starting forming surface from which the winding starts, so the diameter of the transfer roller 6 can be reduced by the value of the inner diameter of the coil.
