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 makes copper rod pass through mold (pressure under external force
Wheel) size copper wire needed for acquisition, it is such as a diameter ofCopper wire, i.e., is heated to certain temperature by second step, copper wire annealing
When, the toughness of copper wire is improved in a manner of recrystallization, reduces the intensity of copper wire；Third walks, conductor process, using 14It is a branch of that copper wire rule, which is twisted, meets requirement on electric performance；4th step, insulation paint immersion coating complete enamelled stranded-wire；5th step,
Silica gel squeezes out cladding, and solid type gel coated enamelled stranded-wire is extruded using silica gel extruding machine；6th step cuts suitable length line
Material；7th step, injection two end lines gear, wire rod one end is put into injection mold and is correctly put, gets togather mold, is noted using injection molding machine
Mould high temperature resistant PP plastic moldings line gear；8th step, compression molding wire rod silica gel outer layer, first will use silica gel moulding press mold into
Type half wire rod silica gel outer layer, which is kneaded 70A silica gel using high resiliency, then one-pass molding silica gel outer layer is put into second set
In mold, the conducting wire that two end line of injection formed is kept off is put into the wire casing that one-pass molding silica gel outer layer reserves, toward mold in fill silicon
Collagen material, the other half silica gel outer layer of compression molding；8th step, wire rod wicking, the enamelled stranded-wire end wicking that will be reserved, by upper
It states step and completes earphone wire making.
Earphone wire made of above-mentioned technique has the following disadvantages, first, Multi-step injection molding is needed to be molded, manufacturing process is answered
It is miscellaneous.Two, silica gel injection molding needs carry out under high-temperature and high-pressure conditions, and insulating lacquer layer thawing is easily easily made to cause to go out between core wire
It now contacts, generates electric signal interference.Three, single enameled wire can not coat thin silicon glue, can only all cores formed it is a branch of after coat
(since silica gel wants high-temperature molding, enameled wire can not coat the flexible glue protective layer of non-refractory), earphone also leads to line in
It rubs between core, the interference of generation makes loudspeaker show apparent noise.Four, enameled wire does not set protective layer and easily scatters, outer layer silica gel
Core is easily broken by mold during molding.Five, silica gel material is easily covered with dust, spraying rubber oil can improve but be cost into
One step increases.Six, silica gel product tears side open certainly is significantly layered wire surface, and whole line appearance is bad.
Invention content

Core wire occurs in machine wire forming method when can be molded to avoid Multi-step injection molding, which melt to approach, causes to interfere with each other noise, reduces technique
Difficulty and fraction defective improve production efficiency.
To solve the above-mentioned problems, the present invention provides a kind of earphone wire forming method, the earphone wire forming method packet
It includes, wire rod fixating shape step is carried out to the wire rod of cutting, which includes, and first the wire rod for being suitble to length is made a reservation for
Type makes wire rod be set in advance as the shape of needs；Hot briquetting is carried out again, and hot briquetting is carried out to the wire rod of pre-setting.
It further says, the hot briquetting is included after the wire rod of pre-setting is put into boiling water boils 2 minutes, line taking material
It is put into 2-3 minutes in normal-temperature water and cools down, complete sizing.
It further says, the hot briquetting includes the wire rod of pre-setting being put into 110-130 ovens toasting 20 minutes
Afterwards, line taking material is put into 2-3 minutes in normal-temperature water and cools down, and completes sizing.
It further says, the pre-setting includes wire rod being fixed in the forming tank on jig, in wire rod ear-hang position
Equipped with the fixed compact heap of jig.
It further says, the compact heap includes rubber block.
It further says, the wire rod middle level that the wire rod is coated on outside enamelled stranded-wire and the line for being coated on wire rod middle level
Material outer layer.
It further says, layer material includes TPE plastic cement in the wire rod.
It further says, the wire rod cladding material includes TPE/TPU plastic cement.
Earphone wire forming method of the present invention includes, and to the wire rod middle level being coated on outside enamelled stranded-wire of cutting and is coated on
The wire rod of the wire rod outer layer in wire rod middle level carries out wire rod fixating shape step, which includes, first to the line of suitable length
Material carries out pre-setting, and wire rod is made to be set in advance as the shape of needs；Hot briquetting is carried out again, and the wire rod of pre-setting is heated
Molding.Due to first carrying out pre-setting to wire rod, then the wire material of pre-setting is put into Baking out in boiling water or oven and is determined
Type, the temperature-controllable of heating had not both been needed to through high temperature and pressure mode secondary injection molding, increased production process, and can be with
High temperature and pressure during secondary injection molding is avoided to be contacted to core wire equivalent damage or core wire, and then improve the quality of earphone wire, is reduced
