Abstract
The invention is suitable for the technical field of an earphone. The invention discloses an earphone wire forming method which comprises a wire shaping step on a cut wire which comprises a wire middle layer that wraps an enameled stranded wire and a wire outer layer that wraps the wire middle layer. The wire shaping step comprises processes of performing pre-shaping on the wire with an appropriate length so that the wire is preset to a required shape; and performing heating forming, namely performing heating forming on the pre-shaped wire. Because pre-shaping is performed on the wire and the pre-shaped wire is placed into boiled water or a baking furnace for performing baking for further shaping, a controllable heating temperature is realized. Not only can secondary injection molding forming in a high-temperature high-pressure mold be saved for preventing production process increase, but also core wire damage or core wire contact caused by the high temperature and high pressure in secondary injection molding forming can be prevented. Furthermore the earphone wire forming method has advantages of improving quality of an earphone wire, reducing process difficulty, and improving product yield rate and production efficiency.
Description
Technical field
The present invention relates to the manufacturing technology field of earphone products, more particularly to a kind of forming method of earphone wire.
Background technology
When existing earphone wire makes, the first step, pulling brass wire make copper rod under external force by mould (pressure
Wheel) required size copper wire is obtained, it is such as a diameter ofSecond step, copper wire annealing, will copper wire be heated to certain temperature
When spending, the toughness of copper wire is improved in the way of recrystallization, reducing the intensity of copper wire；3rd step, conductor process, using 14Copper wire rule is stranded for a branch of, meets requirement on electric performance；4th step, insulation paint immersion coating complete enamelled stranded-wire；5th
Step, silica gel extrusion cladding, extrudes solid type gel coated enamelled stranded-wire using silica gel extruding machine；6th step, cutting suitable length
Wire rod；7th step, is molded two end line shelves, wire rod one end is put in injection mold and is correctly put, get togather mould, using injection machine
Injection high temperature resistant PP plastic rubber shaping line shelves；8th step, compression molding wire rod silica gel outer layer first will be using silica gel moulding press mould
Molding half wire rod silica gel outer layer, the silica gel knead 70A silica gel using high resiliency, then one-shot forming silica gel outer layer is put into second
In mold, the wire of two end line shelves of injection formed is put in the reserved wire casing of one-shot forming silica gel outer layer, the filling toward in mould
Silica gel materials, compression molding second half silica gel outer layer；8th step, wire rod wicking, by the enamelled stranded-wire end wicking for reserving, pass through
Above-mentioned steps complete earphone wire making.
Earphone wire made by above-mentioned technique suffers from the drawback that one is to need Multi-step injection molding molding, and its manufacturing process is multiple
It is miscellaneous.Two, silica gel injection mo(u)lding needs to carry out under high-temperature and high-pressure conditions, and easily melting easily insulating lacquer layer causes to go out between heart yearn
Now contact, produce signal of telecommunication interference.Three, single enamel-covered wire cannot coat thin silicon glue, can only all cores formed it is a branch of after coat
(as silica gel wants high-temperature molding, enamel-covered wire coat the flexible glue protective layer of non-refractory), earphone also causes line using in
Rub between core, the interference of generation makes loudspeaker show obvious noise.Four, enamel-covered wire does not set protective layer and easily scatters, outer layer silica gel
Core is broken by mould easily during molding.Five, silica gel material is easily covered with dust, and spraying rubber oil can improve but be that cost enters
One step increases.Six, silica gel product tears side open certainly is substantially layered wire surface, and whole line outward appearance is not good.
The content of the invention
The invention mainly solves the technical problem of providing a kind of earphone line structure gill machine line forming method, the earphone cord
Forming method can avoid occurring heart yearn during Multi-step injection molding molding and melt to be close to causing to interfere noise, reduce technology difficulty and
Fraction defective, improve production efficiency.
In order to solve the above problems, the present invention provides a kind of earphone cord forming method, and the earphone cord forming method includes, right
The wire rod of cutting carries out wire rod fixating shape step, and the wire rod fixating shape step includes, first the wire rod to being adapted to length carries out pre-setting, makes
Wire rod is set in advance as the shape for needing；Hot briquetting is carried out again, and hot briquetting is carried out to the wire rod of pre-setting.
Further say, the hot briquetting includes the wire rod of pre-setting is put in boiling water boiled after 2 minutes, line taking material
Being put into 2-3 minutes in normal-temperature water cools down, and completes sizing.
Further say, the hot briquetting includes the wire rod of pre-setting is put in 110-130 ovens toasts 20 minutes
Afterwards, line taking material is put into 2-3 minutes in normal-temperature water and cools down, and completes sizing.
Further say, the pre-setting includes wire rod is fixed in the forming tank on tool, in wire rod ear-hang position
It is provided with the compact heap fixed with tool.
Further say, the compact heap includes block rubber.
Further say, the wire rod includes the wire rod middle level being coated on outside enamelled stranded-wire and is coated on the line in wire rod middle level
Material outer layer.
Further say, in the wire rod, layer material includes TPEE plastic cement.
Further say, the wire rod cladding material includes TPE/TPU plastic cement.
