Abstract

A device for removing insulation from wires containing a heater including a nichrome spiral and a unit for removing insulation residues, characterized in that a tube of heat-resistant insulating material is installed inside the nichrome spiral, and a unit for removing insulation remains is made in the form of rotating sleeves made of porous elastic material , while the device is equipped with a power supply and a time relay.

Description

DEVICE FOR REMOVING INSULATION FROM WIRES

The business modem is dedicated to the field of electrical engineering and can be integrated into any branch of the national economy, where there is a need to remove the volition from the wires.

A device for removing insulation from wires containing a gas burner is known (see P.I. Yoftifeev Welding and soldering of insulated wires, Leningrad, Mashmoetroenie, 1985, p. 1718, Fig. 1.6 gd).

A disadvantage of the known device is the need to organize a specially equipped workplace that meets safety requirements, as well as the cost of receiving and storing gas.

Closest to the claimed utility model is a device for removing the insulator from the wires, containing a heater including a straight spiral and a unit for removing residual insulation (see AS USSR 756532, class N02 & 1/12, 1980), taken as a prototype .

The disadvantages of the prototype include low productivity, because due to the need to insert and turn off the heater in each Ш1кл wire firing, as well as wring out the reservoir with coolant, the cycle time of firing and cleaning the wire increases. In addition, the prototype does not allow to clear the conps of the wire at a distance of 10 mm from the body of the product due to Heo6xo | i | fttiop input of the wire into the heater through the node for removing insulation. At the same time, the use of asbestos, from which the cleaning unit is made, is undesirable due to the release of substances harmful to health,

The task of this fashioned modem is to provide a simple device for removing electric wires from wires in the serial production of electrical equipment.

The technical result is the provision of high quality wire cleaning from I8olash1i, elimination of overheating of the meaogs wire, saving electrical energy, reducing firing time.

The specified technical result in the implementation of the polarized model is achieved by the fact that in the device for removing insulation from wires containing a heater including a nichrome spiral and removed to remove insulation residues, the peculiarity lies in the fact that a tube of heat-resistant insulating material is installed inside the nichrome spiral, and the unit for removing insulation residues is made in the form of a rotating B17lock of porous elastic material, while the device is equipped with 1 {power supply and time relay

 A useful mod is represented by a drawing, which shows a diagram of a device for stripping wires.

A device for removing insulation from drives contains a heater including a nichrome spiral I e with an inner diameter

 6 mm, inside of which a tube 2 is installed made of heat-resistant insulating material (for example, ceramic), which excludes the closure of spiral coils by a wire and creates a uniform stable temperature in the firing; a unit for removing residual insulation in the form of rotating sleeves 3 from a spongy elastic material (for example, felt), a power supply 4, providing adjustable heating of the spiral I, a timer 5, turned on by a push button switch 6, a bulb 7.

The operation of the device for stripping the wires is as follows.

Vdda 8 regulates the filament of the spiral with the nomoci of the regulator of the power unit 4. By doing this, the burner burns or the wire overheats (in the case of firing a very thin wire). The connecting wire 8 is placed inside the ceramic tube 2. At the same time, using the pushbutton 6, turn on the time switch 5, which is configured depending on the thickness of the wire 8, and which includes a light indication at the end of the firing. As a result of firing, the insulation of the wire is burned. At this moment, the light indication turns on (lamp 7 lights up) and wire 8 is immediately removed from tube 2. The presence of a time relay 4 allows you to accurately record the end time of firing, which eliminates overheating of the copper wire, saves energy and reduces the time of removing insulation. After cooling, wire 8 is run between rotating felt sleeves 3, as a result of which it is cleaned of scale and insulation residues. Now the wire is ready for connection in the product, for example, in the relay coil.
