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
The present invention relates to enamel-cover sintering line processing technique field, be specially a kind of enamel-cover sintering line processing technique.
Background technology
Conventional machining process is that the twisted filament winding using proportioning to cross wraps on qualified enamel-covered wire, uses baking box repeatedly to heat, causes dacron thread therein to dissolve, be attached on enamel-covered wire by bonding, act primarily as protective paint envelope curve insulating barrier and the effect of certain voltage.But owing to paint film is continuing in an environment of high temperature, paint film itself can be caused certain damage, directly reduce the proof voltage of enamel-covered wire itself.The excessive minimum of voltage pulsation is at several hectovolts, and height then arrives several kilovolts.
Need in baking process to shut down, clusters is changed in start simultaneously, and after most easily causing shutdown, product surface turns white, and after start, color recovers again normal etc..Cause a dish interiors of products color inconsistent.
The product produced under this technique has a paint film cracking being curved experiment, and tack experiment has insulating barrier obscission, and conforming product rate can not get improving always.
Moreover there will be the phenomenon such as wildness, rough, obfuscation with the product of traditional twisted silk processing, greatly reduce the quality of product itself.
Summary of the invention
The purpose of the present invention is aiming at the defect of tradition enamel-cover sintering line production technology existence and improves, it is provided that a kind of enamel-cover sintering line processing technique.This enamel-cover sintering line technique uses high frequency transient heating to make enamelled coating form an overall external insulation layer with dacron thread, glass fiber strong bond, uses 360 twisted silk proportionings to carry out wrapped.The enamel-cover sintering line that present invention process produces, to the paint film of enamel-covered wire without any damage in sintering process, product surface is without fluffing, smooth, shinny, and the performance such as the insulating barrier tack of product, breakdown voltage is all greatly improved.
A kind of enamel-cover sintering line technology scheme of the present invention is, a kind of enamel-cover sintering line processing technique, it is characterised in that comprise the following steps:
(1) 360 twisted silks (360 i.e. 360 dacron threads of twisted silk/glass fiber composite fibre, 360 refer to model) are used to carry out proportioning wrapped；Proportioning is wrapped is two processes, and proportioning refers to the proportioning of silk, wrapped refers to filament winding on conductor.
(2) heating
High frequency transient heating is used to make enamelled coating form an overall external insulation layer with dacron thread, glass fiber strong bond；
(3) heat complete cooling down, make external insulation layer more firm with bonding lacquered wires；
(4) dry.
Step (1) is 360/1+30D silk union by silk specification, adds the mixing of 5%-10% dacron thread；The silk union quantity of configuration is according to copper conductor size proportioning silk union, and copper conductor is the biggest, and the silk union quantity of configuration is the most.
Step (2) heats, and uses HF induction heating apparatus to heat, and temperature is 340-360 DEG C.
Step (3) heats complete cooling down, makes external insulation layer surface cooling to 20-30 DEG C, can be selected for circulating water in 5 seconds.
Step (4) is dried furnace temperature and is 65-95 DEG C.
In step (4) drying course, speed is 3.5-4.5 m/min.
Preferably, in step (4) drying course, speed is 4 ms/min
The invention have the benefit that this enamel-cover sintering line technique uses high frequency transient heating to make enamelled coating form an overall external insulation layer with dacron thread, glass fiber strong bond, use 360 twisted silk proportionings to carry out wrapped.Have employed the enamel-cover sintering line that present invention process produces, its voltage performance improves about 2000-4000V, and voltage performance is stable at 4000V-5500V.The appearance property of product is obviously improved, and product surface is without fluffing, smooth, shinny.To the paint film of enamel-covered wire without any damage in sintering process, the performances such as the physical and mechanical properties of product does not has any reduction, and the insulating barrier tack of product is stable, breakdown voltage are all greatly improved, after carrying out stretching and bend test, the insulating barrier of product is without significantly cracking and obscission.
Detailed description of the invention:
In order to be more fully understood that the present invention, describe technical scheme in detail with instantiation below, but the invention is not limited in this.
Embodiment 1
It is wrapped that enamel-covered wire uses 360 sth. made by twisting and silk to carry out monolayer bias, wrapped complete after do not use baking oven to toast, high-frequency heating apparatus is used to carry out high-frequency heating baking, require that actual thermometric is at about 350 DEG C, the product sintered cools down, in 5 seconds, make external insulation layer surface cooling to 20-30 DEG C, can be selected for circulating water.The product voltage stabilization made according to this processing technique, any surface finish, every mechanical performance and electrical property are excellent.It is technical data shown in table 1:
Table 1
。
Note: furnace temperature refers to the temperature of baking oven, electromagnetic wire is after water cooling, through oven for drying.Speed refers to the Trace speed of electromagnetic wire.
Suitably furnace temperature can dry the water on electromagnetic wire, will not bake again the insulating barrier of bad electromagnetic wire.The size of speed affects the electromagnetic wire time through high-frequency apparatus, the time that i.e. electromagnetic wire heats on high frequency.
Carried out the enamel-cover sintering line produced by above-mentioned technique, the properties of product has remarkable improvement than in the past.Concrete as shown in table 2:
Table 2
。
