Wire winding machine winding skills on the characteristics of the type of wire being wound, the number of turns and the appearance of the material, winding speed to have such as self-adhesive wire, enameled cotton wire, etc., the diameter of the set wire to increase a lot, because the outer skin is not too smooth, more non-inertial characteristics. The winding speed of fine wire should not be too slow, but start with a slow crawl to avoid pulling the wire off. Coarse wire should not be too fast (over speed), but pay attention to whether the low and medium speed torque is sufficient. When using aluminum wire, please note that the up force should be adjusted to the same thickness than the copper wire is much smaller, so as not to pull the wire diameter thin, the outer insulation paint burst, affecting product quality. When using aluminum wire because of the reduction in up force, the set wire diameter should be increased appropriately. Combined with their own up force needs can go less.

Slip ring heat treatment methods

(1) slip ring coaxial cooling air volume is not enough to deal with the method. Take measures to increase the cooling ventilation, such as external installation of axial fan cooling. Brush or slip ring temperature is high when you can start the fan to strengthen the surface heat exchange, cooling effect is ideal. Regularly use dry, clean compressed air to blow the accumulated dust and powder of the slip ring, slip ring outer cover dust, check and unclog the slip ring small hole after shutdown, check and clean the air inlet screen.

(2) Improve the quality of brush maintenance, timely elimination of heat defects as far as possible using the manufacturer’s original brush and brush box. Carbon brush in the brush grip should move up and down freely, the gap between the carbon brush and brush grip should be 0.1 ~ 0.2mm, the brush should not jump, shake or stuck; brush grinding surface is bright and free of impurities, the spring pressure should be adjusted to 11 ~ 12N, the pressure is too small should be replaced by a new brush or adjust the pressure, the surface temperature of the slip ring should not be greater than 120 ℃. In addition, when the brush wears away 2/3 of its height or poor contact, it should be changed. Brush frame should be free of accumulated dirt, slip ring surface oxide film is too thick or rough surface is not smooth, apply fine abrasive cloth or white cloth polishing, prohibit the use of rough abrasive cloth polishing.
