Description

The invention relates to process equipment for the preparation of electrical wires for installation and can be used in the electrical, electronic and instrument-making industries.

The purpose of the invention is to increase the reliability and quality of wire processing.

The drawing shows a device for stripping insulation from wires (in a compressed state), a general view.

The device for stripping insulation from wires comprises a housing consisting of two parts 1 and 2 connected by an axis of rotation 3 and a return spring 4. In the case holders are mounted — thermal screens 5 and 6, on which by means of straps 7-9. and brackets 10 fixed corrugated tapes 11 - 13. Of electrically conductive material with inserted between: corrugations machining 14 and 15 and insulating 16 plates. The processing plates are covered with an insulating layer 17, for example, with a sieve, Cement, In the first processing plate 14 there is a round hole 18 for ring-burning the insulation. The remaining processing plates 15 have an i-shaped groove 19 for fixing the wire 20. The power supply wires 21 are connected to the ends of the corrugated tapes 11-13.

The device works as follows.

In the initial position between the two rows of processing plates 15, there is a gap necessary for insertion of the wire 20. The end of the processed wire 20 is introduced into the device through the opening 18 to the required depth.

Squeezing the device by hand and breaking the resistance of the spring 4, the wire 20 is fixed in the U-shaped grooves 19 of the processing plates 15. After the power supply circuits are closed, resistive heating of the corrugated strips 11 - 13 occurs, and from them - the processing plates 14 and 15 to the required temperature.

Thanks to the separate chains, the feeding of the firing tape 11 and the tapes 12 and 13

softening insulation (in a three-wire scheme with one common wire) separate temperature control for firing and softening insulation is possible.

The part of the wire 20 protruding from the device is diverted from the axis of the device and rotated one turn so that from the movement of the wire 20 along the heated wall of the hole 18 on the insulation of the wire an annular groove is formed. Then, by applying the force applied to the wire 20 along the axis of the device, the wire is removed from the cut off section of the insulation fixed in the device.

Introducing machined insulated plates from a construction material into the device eliminates the possibility of electrically closing the supply circuits during operation and increases the rigidity of the softening and securing unit, which reduces the mechanical wear of the corrugated tape and increases the failure of the device.

The implementation of the firing element of the insulation of wires with the use of heat-resistant structural materials ensures the safety of the smooth edge of the hole in the firing element, which reduces damage to the current-carrying veins of the wires being processed, improving the quality of processing.
