Ubwino wa Kuwotcherera ndi Laser mu Makampani Opanga Zodzikongoletsera

Kuwotcherera kwa laserimapereka mphamvu yowotcherera komanso liwiro lalikulu, komanso chiŵerengero chochepa chokana, zomwe zimapangitsa kuti igwiritsidwe ntchito kwambiri popanga zinthu zamakono. Mu makampani opanga zodzikongoletsera, poyerekeza ndi njira zachikhalidwe zowotcherera, kuwotcherera ndi laser kuli ndi ubwino waukulu.

1. Liwiro lapamwamba, mphamvu yayikulu, kupotoza kochepa - sikufunika kuwongola kapena kuyeretsa pambuyo pa weld
Chifukwa chachikuluopanga zodzikongoletseraKugwiritsa ntchito kwambiri laser welding ndiko kuthamanga kwake kowotcherera komanso kusokoneza kochepa, zomwe zimachotsa kufunikira kowongoka ndi kuyeretsa pambuyo pa welding. Ngakhale kuti laser welding ndi yachangu kuposa lawi lachikhalidwe, wogwiritsa ntchito nthawi zambiri amagwira ntchito ndi manja kapena zida, kuwotcherera chidutswa chimodzi panthawi. Popeza malo ambiri ogwirira ntchito a laser welding a zodzikongoletsera ndi ang'onoang'ono ndipo sangathe kukonza magulu akuluakulu nthawi imodzi, nthawi yowotcherera ingawonjezere pang'ono. Komabe, kuchepa kwa ntchito yoyeretsa pambuyo pa welding kumakwaniritsa nthawi yowotcherera. Laser welding ikhoza kuchitika pansi pa mpweya wopanda mpweya, osasiya madontho a moto pa chinthucho. Chifukwa chake, palibe kusuntha komwe kumafunika, ndipo palibe kusankhidwa kwa asidi pambuyo pa welding. Ponseponse, laser welding imapangitsa kuti pakhale ntchito yabwino kwambiri yopanga.

2. Yoyenera kulumikiza ziwalo zolondola, kuonetsetsa kuti ntchitoyo ndi yabwino.
Popeza kuwala kwa laser kumatha kuyikidwa pamalo ang'onoang'ono kwambiri ndikuyikidwa bwino, ndikwabwino kwambiri popanga zinthu zokha zokha. Izi zimathandizira kwambiri kupanga bwino, zimachepetsa malo omwe kutentha kumakhudza, komanso zimasunga zinthu zodetsa zomwe zimasungunula, zomwe zimapangitsa kuti ubweya ukhale wabwino kwambiri komanso zimachepetsa kuchuluka kwa zolakwika. Mwachitsanzo, polumikiza zodzikongoletsera za 14K alloy ndi 58% Au ndi 2% Ag ndi kulemera, siliva amasungunuka, zomwe zimachepetsa kuuma konse kwa chidutswacho kuyambira pafupifupi HV 145 mpaka pafupifupi theka. Ngati chagwetsedwa kuchokera kutalika kwa m'chiuno kupita pansi, chingasweke. Pogwiritsa ntchito welding ya laser yothamanga kwambiri, kutentha kumakhala kochulukira, kotero kuti chogwirira ntchitocho sichimasungunuka, motero chimakhalabe ndi mphamvu.

3. Kukonza bwino kwambiri, zomwe zimathandiza kupanga njira zatsopano zopangira zodzikongoletsera.
Chiyambi chakuwotcherera ndi laserKulowa mu makampani opanga zodzikongoletsera kwasintha malingaliro achikhalidwe pakupanga zodzikongoletsera. Ndi kuwotcherera kwa laser, mitundu yapadera ya kapangidwe kake imatha kupangidwa. Kale, mapangidwe apadera awa anali ovuta kapena osatheka kupangidwa ndi kuwotcherera kwachikhalidwe. Kuwotcherera kwa laser kumatha kuchitika m'malo opapatiza kwambiri, zomwe zimapangitsa kuti zikhale zosavuta kuwotcherera mitundu yosiyanasiyana ya zinthu za alloy pamodzi. Chifukwa chake, mtundu kapena kapangidwe pakati pa zigawo ziwiri zimatha kusintha mwadzidzidzi popanda kusakanikirana. Malo ogwirira ntchito ochepa a kuwotcherera kwa laser amachititsa kusiyana kwa kunyowa, umphumphu wa majoini, ndi kukula kwa tirigu m'dera lomwe lakhudzidwa ndi kutentha poyerekeza ndi kuwotcherera kwachikhalidwe.

4. Kukhazikika bwino komanso kukhazikika.
Kawirikawiri, sipafunika chitsulo chodzaza kapena madzi oundana - chogwirira ntchitocho chikhoza kusungunuka m'deralo ndikuwotcherera mwachindunji.

5. Kumafewetsa ntchito yokonza zinthu zina.
Mwachitsanzo, kukonza zitsulo pafupi ndi miyala yamtengo wapatali, kuchotsa mabowo oponyera zinthu, ndi kuwotcherera m'malo okwana 0.2 mm ku zinthu zovuta komanso zosavutikira kutentha monga ma hinges, ma hook, ma clasp, ndi malo okonzera.

6. Palibe kuipitsa chilengedwe.
Pakuwotcherera ndi laser, sipagwiritsidwa ntchito solder kapena solvent, komanso mankhwala oyeretsera safunikira, kotero palibe vuto lotaya zinyalala.

7. Kusunga zinthu zamtengo wapatali zachitsulo.
Kuwotcherera kwachikhalidwe nthawi zambiri kumafuna makulidwe achitsulo pafupifupi 0.2 mm, pomwe kuwotcherera kwa laser kumatha kuchepetsa izi kufika pa 0.1 mm. Izi zimachepetsa kulemera kwa chokongoletsera ndi pafupifupi 35–40%, zomwe ndizofunikira kwambiri pazinthu zopangidwa ndi magetsi. Kuwotcherera kwa laser sikuti kungopulumutsa zinthu zamtengo wapatali zachitsulo komanso kumasunga solder, ndipo pa ma weld angapo, mitundu yosiyanasiyana ya solder sikufunika.

8. Makhalidwe
Makina ochapira zitsulo pogwiritsa ntchito laser omwe amagwiritsidwa ntchito popanga zodzikongoletsera ndi otsika mphamvu, amakhala otetezeka kwambiri, opapatiza, komanso osavuta kuyenda, zomwe zimathandiza wogwiritsa ntchitoyo kugwira ntchito bwino atakhala pansi.
Makina ogwiritsira ntchito laser odzola zodzikongoletsera amatha kusungunula zitsulo ndi ma alloy ambiri mwachangu, modalirika, komanso molondola, ngakhale kuti kugwira ntchito bwino kumadalira kwambiri momwe zinthuzo zimagwirira ntchito. Kukonza kapena kusonkhanitsa zinthu mosalekeza kumatha kuchitika motsogozedwa ndi laser imodzi kapena zingapo, nthawi zambiri kugunda kulikonse kumatha 1-20 ms. Pogwiritsa ntchito microscope ya stereo yokhala ndi ma crosshairs, malo olumikizirana amatha kuyikidwa bwino, ndipo chogwirira ntchitocho chikhoza kusinthidwa bwino mkati mwa malo owonera. Malo ogwirira ntchito nthawi zambiri amakhala amlengalenga; kulowetsa mpweya kapena mpweya wopanda mpweya pamalo ogwirira ntchito kumapereka kuziziritsa, ndipo mpweya wopanda mpweya umathandizanso kuti ma alloy azizire.

9. Mphamvu ya Zipangizo za Alloy pa Laser Welding Effect
Zipangizo zosiyanasiyana za aloyi zimakhala ndi zotsatira zosiyana za kuwotcherera ndi laser. Pansi pa magawo ofanana owongolera a makina owotcherera ndi laser komanso ndi kutentha komweko komwe kumasamutsidwa pa kuwotcherera, mphamvu yosungunula pa kuwotcherera imasiyana chifukwa cha kusiyana kwa kuchuluka kwa kutentha komwe kumayamwa (m'malo mowonetsedwa) ndi pamwamba pa zinthu za aloyi. Zinthu zina zomwe zimakhudza zimaphatikizapo mphamvu ya kutentha kuyambira kutentha kwa chipinda mpaka kutentha, kutentha, kutentha kobisika kwa fusion, ndi kutentha. Zipangizo zosiyanasiyana zimakhala ndi kutentha kosiyana, kutentha kosungunuka, ndi kutentha kobisika kwa crystallization. Zonsezi pamodzi, zinthuzi zimakhudza kwambiri mphamvu yofunikira kuti kuwotcherera kugwire ntchito bwino. Kuyamwa kutentha kokwanira pamwamba ndikofunikira kuti kuwotcherera kugwire bwino ntchito.
