Embodiment １

[0022] The enameled wire is wrapped with 360 twists and wires for single-layer eccentric wrapping. After the wrapping is completed, no oven is used for baking, and high-frequency heating equipment is used for high-frequency heating and baking. The actual temperature measurement is required to be around 350°C. Cooling, the surface of the outer insulating layer is cooled to 20-30°C within 5 seconds, and circulating water can be used for cooling. Products made according to this processing technology have stable voltage, smooth surface, and excellent mechanical and electrical properties. Shown in table 1 is process technology parameter:

[0025] Note: The furnace temperature refers to the temperature of the oven. After the electromagnetic wire is cooled by water, it is dried in the oven. The speed of the vehicle refers to the speed of the electromagnetic wire.

[0026] The proper furnace temperature can not only dry the water on the electromagneti...

Abstract

The invention discloses an enameled sintered wire processing technology. According to the enameled sintered wire processing technology, a paint layer, polyester yarn and glass silk are firmly bonded to form an integral outer insulating layer by means of high-frequency transient heating, and wrapping is conducted through matching of 360 twisted yarn. According to an enameled sintered wire produced with the processing technology, a paint film of an enameled wire is not damaged at all during sintering, the surface of a product is free of fuzzing, smooth and glossy, and the adhesiveness of the insulating layer, breakdown voltage and other performance of the product are improved greatly.

Description

technical field [0001] The invention relates to the technical field of enamelled sintering line processing, in particular to an enameled sintering line processing technology. Background technique [0002] The traditional processing technology is to use the proportioned twisted wire to wrap the qualified enameled wire, and use the oven to heat repeatedly, so that the polyester wire in it melts and adheres to the enameled wire through bonding, mainly to protect the enameled wire insulation layer and a certain voltage. role. However, due to the continuous high temperature environment of the paint film, it will cause certain damage to the paint film itself, which directly reduces the withstand voltage of the enameled wire itself. Excessive voltage fluctuations range from a few hundred volts to several thousand volts. [0003] At the same time, during the baking process, it is necessary to stop the machine and start the machine to replace the silk balls, which is most likely to...
