Njira yowotcherera laser
Ndiwofunika kwambiri komanso amagwiritsidwa ntchito kwambiri m'makampani opanga magalimoto, pomwe mapanelo amagalimoto ndi amodzi mwamagulu akulu asanu a kuwotcherera kwa laser.
Imagwiritsidwa ntchito pamagalimoto, imatha kuchepetsa kulemera kwagalimoto, kukonza kulondola kwa gulu lagalimoto, kukulitsa kuuma kwa thupi lamagalimoto, ndikuchepetsa kupondaponda ndi kusonkhanitsa ndalama popanga magalimoto.
Zida zowotcherera za Xinfa zili ndi mawonekedwe apamwamba komanso otsika mtengo.Kuti mudziwe zambiri, chonde pitani:Opanga Kuwotcherera & Kudula - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Laser self-fusion stack kuwotcherera kwa magawo agalimoto yamagalimoto
Pamene mtengo wa laser wokhala ndi kachulukidwe ka mphamvu kamene kafika pamtundu wina (106 ~ 107 W / cm2) umayatsa pamwamba pa zinthuzo, zinthuzo zimatenga mphamvu zowunikira ndikuzitembenuza kukhala mphamvu ya kutentha.Zinthuzo zimatenthedwa, zimasungunuka, ndi kutenthedwa, kutulutsa mpweya wambiri wachitsulo, womwe umatuluka pamwamba.Pansi pa mphamvu yomwe imapangidwa ndi laser, madzi osungunuka achitsulo amakankhidwa mozungulira kuti apange maenje.Pamene laser ikupitiriza kuyatsidwa, maenjewo amalowa mozama.Laser ikasiya kuyatsa, madzi osungunuka ozungulira maenjewo amabwereranso ndikuzizira ndi kukhazikika.Wonjezerani zida ziwirizo pamodzi.
Zinthu zomwe zimakhudza kuwotcherera kwa laser
1. Mphamvu ya laser
Pali kachulukidwe kamphamvu ka laser mu kuwotcherera kwa laser.Pansi pa mtengo uwu, kusungunuka kwapamwamba kokha kwa workpiece kumachitika, ndipo kuya kwake kumakhala kosazama kwambiri, ndiko kuti, kuwotcherera kumachitidwa mumtundu wokhazikika wa kutentha;mtengo uwu ukafikiridwa kapena kupitirira, plasma idzapangidwa, chomwe ndi chizindikiro cha Kupita patsogolo kwa kuwotcherera kwakuya kokhazikika, kuya kwake kudzawonjezeka kwambiri.Ngati mphamvu ya laser ndi yotsika kuposa pakhomo ili ndipo mphamvu ya laser ndiyochepa, kulowetsa kosakwanira kudzachitika ndipo ngakhale ndondomeko yowotcherera idzakhala yosakhazikika.
2. Kuwotcherera liwiro
Liwiro kuwotcherera ali ndi chikoka chachikulu pa malowedwe kuya.Kuwonjezeka kwa liwiro kumapangitsa kuti kulowako kusakhale kozama, koma ngati liwiro liri lotsika kwambiri, limayambitsa kusungunuka kwambiri kwa zinthu ndi kuwotcherera kwa workpiece.Choncho, pali oyenera kuwotcherera liwiro osiyanasiyana zinthu yeniyeni ndi mphamvu laser ndi makulidwe enaake, ndi malowedwe pazipita akhoza analandira pa lolingana liwiro mtengo.
3. Defocus kuchuluka
Kuti mukhalebe kachulukidwe kamphamvu kokwanira, malo olunjika ndikofunikira.Pa ndege iliyonse yomwe ili kutali ndi cholinga cha laser, kugawa kwamagetsi kumakhala kofanana.Pali mitundu iwiri ya defocus: positive defocus ndi negative defocus.Pamene ndege yoyang'ana ili pamwamba pa chogwirira ntchito, imakhala yabwino, ndipo ikakhala pamwamba pa chogwirira ntchito, imakhala yosokoneza.Kusintha kwa defocus kumakhudza mwachindunji m'lifupi ndi kuya kwa weld.
4. Gasi woteteza
Pakuwotcherera kwa laser, mipweya ya inert imagwiritsidwa ntchito kuteteza dziwe losungunuka, koma nthawi zambiri, mipweya monga argon, nayitrogeni, ndi helium nthawi zambiri imagwiritsidwa ntchito poteteza chogwirira ntchito ku okosijeni panthawi yowotcherera ndikuwotcherera. plasma.
