Abstract
The present invention discloses an enamel-removing method for enameled wire of coil lead-out position, namely, sodium hydroxide saponification enamel-removing method. Said method includes the following steps: fixing the coil having need of removing enamel on a special-purpose spring clamp apparatus, placing its lead-out portion into an enamel-removing pot containing sodium hydroxide to dissolve enamel, then placing said lead-out portion into boiling water, then placing it into running water and flushing, finally drying in baking oven.
Description
One, technical field
The present invention relates to a kind of coating removal method of enamelled wire, relate to the coating removal method that a kind of coil is drawn the position enamelled wire in particular.
Two, background technology
Coil is meant the assembly that is made of one or more windings and bobbin, wrapping layer etc., and various types of electromagnetic systems all be can't do without coil, and it is relay " heart ", and the reliability of its work has directly influenced the reliability of relay.The lead-out mode of relay coil is that the pure nickel line with φ 0.2mm welds again after will drawing the enamelled coating removal of enamelled wire.The coating removal method that the existing relay coil is drawn enamelled wire adopts the manual sand of abrasive paper for metallograph to remove paint film always, because the enamelled wire line of relay coil footpath is little, major part is between φ 0.025mm～φ 0.08mm, in sand the end of a thread enamelled coating, sand coating removal layer not only, simultaneously also sand to the copper cash of enamelled wire inside, sand to the position copper wire diameter attenuate, and because rubber is coarse, the position copper line surface that sand arrives is uneven, very easily cracks.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of coil to draw the coating removal method of position enamelled wire, adopt NaOH saponification coating removal method with chemical reagent removal enamelled coating.
The coating removal method that a kind of coil of the present invention is drawn the position enamelled wire is:
After being wound on enamelled wire on the skeleton, two enamelled wires of fixedly drawing with polytetrafluoroethylraw raw material band, with special purpose spring clamping alignment circle, the enamelled wire of pre-coating removal is wrapped in special purpose spring folder bottom, melt and maintenance filling to be heated on coating removal pot (casting iron pan of surface-coated 10 μ m～thick nickel dam of 30 μ m) the placement electric furnace of concentration greater than 96% above NaOH, thereafter in the NaOH after clamping is good coil immersion is melted, 5-20 takes out after second, 90 ℃ of-100 ℃ of boiling water are put at position behind the coil coating removal immediately, the remaining hydrogen sodium oxide molybdena at coating removal position is disposed in dissolving, after put into running water flushing 5-15 number minute, thoroughly to clean up residual NaOH, after put into baking oven and dry, enamelled wire behind the coating removal and nickel wire welding are put into coil clamp again and the coil of anchor clamps behind bonding wire put into alcohol are carried out soaking and washing, after put into baking oven and dry, two nickel wire bendings are put, fixing with the polytetrafluoroethylene film wrapping, finish whole winding coating removal process.
The invention has the beneficial effects as follows that having solved traditional enamelled wire coating removal internal copper line loss hinders, the coil breakage problem has satisfied the requirement of relay coil work high reliability.Solved the bottleneck of production expansion amount, coil output is brought up to 70,000 of monthly outputs by about 30,000 of original monthly outputs.
Four, description of drawings
Five, embodiment
Coil of the present invention is drawn the concrete implementation step of coating removal method of position enamelled wire for enamelled wire is wound on the skeleton, two enamelled wires of fixedly drawing with polytetrafluoroethylraw raw material band;
Coil is inserted in the circle of special purpose spring folder, upwards tightens up the copper wire of special purpose spring folder, coil can not be swung in the special purpose spring folder, two enamelled wires of pre-coating removal are wrapped in the lower end of special purpose spring folder;
Concentration is not less than 96% NaOH (in right amount) and puts into coating removal pot (casting iron pan of the thick nickel dam of surface-coated 20 μ m), then the coating removal pot is placed and be heated to thawing (300 ℃) and maintenance on the electric furnace, coil is penetrated special-purpose coating removal anchor clamps, form a row, the sodium hydroxide solution of putting into the coating removal pot took out after 10 seconds, finished and removed the requirement of drawing enamelled wire surface enamelled coating;
Boiling water is put at position behind the coil coating removal immediately, is disposed the remaining hydrogen sodium oxide molybdena at coating removal position with dissolving, after put into running water flushing several minutes, thoroughly to clean up the remaining hydrogen sodium oxide molybdena.Putting into baking oven at last dries.
With the welding of the enamelled wire behind the coating removal and nickel wire, put into coil again and put anchor clamps, the coil of anchor clamps behind bonding wire put into alcohol carries out soaking and washing, after put into baking oven and dry;
Two nickel wire bendings are put, fix, finish the production process of whole winding coating removal with the polytetrafluoroethylene film wrapping.
Because coating removal technology is to adopt the NaOH liquefaction solvent of high temperature, human body skin is burnt seriously, if adopt traditional while winding the line the production model of coating removal, the operator accidentally will produce danger, for this reason, and the principle that adopts operation to disperse, fixing local to the coating removal procedure arrangement, specify special messenger's operation, and safety devices such as air draft, temperature control are arranged, to solve the processing safety problem.
Claims (2)
1. a coil is drawn the coating removal method of position enamelled wire, it is characterized in that: this method is coil to be drawn the position immerse in the NaOH coating removal pot and remove enamelled coating, and its step comprises:
A. coil is inserted in the circle of special purpose spring folder, upwards tightens up the copper wire of special purpose spring folder, coil can not be swung in the special purpose spring folder, two enamelled wires that need coating removal of reserving are wrapped in the lower end of special purpose spring folder;
B. concentration is not less than 96% NaOH and puts into the coating removal pot that surface-coated has nickel dam, the coating removal pot is placed be heated on the electric furnace then and melted and maintenance, coil is penetrated special-purpose coating removal anchor clamps, form a row, put into the sodium hydroxide solution of coating removal pot, treat lacquer dissolving back taking-up, finish and remove the requirement of drawing enamelled wire surface enamelled coating;
C. boiling water is put at the position behind the coil coating removal immediately, melting the remaining hydrogen sodium oxide molybdena at coating removal position, after put into running water flushing several minutes, thoroughly to clean up the remaining hydrogen sodium oxide molybdena, put into baking oven at last and dry.
2. a kind of coil according to claim 1 is drawn the coating removal method of position enamelled wire, it is characterized in that: described coating removal pot is a casting iron pan, and scribbles the nickel dam that thickness is 10-30 μ m on the surface.
