Ukadaulo wozimitsa wa laser ndi njira yomwe imagwiritsa ntchito mtengo wokhazikika wa laser kuti itenthetse mwachangu pamwamba pazida zachitsulo, ndikupangitsa kuti isinthe magawo ndikupanga wosanjikiza wozimitsa wa martensite. Laser quenching ali ndi kachulukidwe kwambiri mphamvu ndi liwiro kuzirala mofulumira. Sichifuna kuzirala media monga madzi kapena mafuta. Ndi njira yaukhondo komanso yofulumira kuzimitsa. Kenako, mkonzi adzakufotokozerani kugwiritsa ntchito ukadaulo wa laser quenching. Poyerekeza ndi kuzimitsa kulowetsedwa, kuzimitsa lawi, ndi kuzimitsa moto, kuzimitsa kwa laser kumakhala ndi yunifolomu yowuma, kuuma kwakukulu (nthawi zambiri 1-3 HRC yokwera kuposa kuzimitsa induction), kusinthika pang'ono kwa chogwirira ntchito, kuwongolera kosavuta kwa kuya kwa kutentha ndi kutentha. trajectory, komanso automation yosavuta, palibe chifukwa chopanga ma coil ofananirako molingana ndi kukula kwa magawo osiyanasiyana monga kuzimitsa kwa induction, ndipo kukonza kwa zigawo zazikulu sikuyenera kuchepetsedwa ndi kukula kwa ng'anjo panthawi yochizira kutentha kwamankhwala monga carburizing ndi kuzimitsa. Chifukwa chake, m'mafakitale ambiri, pang'onopang'ono m'malo mwa induction. Njira zachikhalidwe monga kuzimitsa ndi kutentha kwa mankhwala. Chofunikira kwambiri ndikuti mapindikidwe a workpiece isanayambe komanso itatha kuzimitsa kwa laser kumakhala kocheperako. Choncho, makamaka oyenera mankhwala padziko mbali ndi mkulu mwatsatanetsatane zofunika. Kuya kwa wosanjikiza laser-oumitsa zimadalira chigawo zikuchokera, kukula ndi mawonekedwe, ndi magawo laser ndondomeko, ndipo zambiri mu osiyanasiyana 0.3-2.0mm. Mwa kuzimitsa malo a mano a magiya akuluakulu ndi magazini a zigawo zazikulu za shaft, kuuma kwapamwamba kumakhalabe kosasinthika ndipo kumatha kukwaniritsa zofunikira zenizeni zogwirira ntchito popanda kufunikira kwa makina otsatila.

Ukadaulo wosungunula ndi kuzimitsa kwa laser ndi njira yomwe imagwiritsa ntchito mtengo wa laser kutenthetsa pamwamba pa gawo lapansi pamwamba pa kutentha kosungunuka. Chifukwa cha kuziziritsa kwa kutentha kwapakati pa gawo lapansi, pamwamba pazitsulo zosungunuka zimakhazikika mofulumira ndikukhazikika. Mapangidwe osungunuka ndi kuzimitsa omwe apezeka ndi owuma kwambiri, ndipo kapangidwe kamene kakuyenda mozama ndi gawo losungunuka losungunuka, kusintha kwa gawo lowumitsa, malo okhudzidwa ndi kutentha, ndi zinthu zoyambira. Wosanjikiza wosungunuka wa laser amakhala ndi kuya kwakuya kowumitsa, kuuma kwakukulu, komanso kukana kuvala bwino kuposa kusanjika kwa laser quenching. The kuipa kwa luso limeneli ndi kuti roughness wa workpiece pamwamba kuonongeka kumlingo, ndipo wotsatira makina processing zambiri chofunika kubwezeretsa. Pofuna kuchepetsa roughness pamwamba mbali pambuyo laser kusungunuka mankhwala ndi kuchepetsa kuchuluka kwa processing wotsatira, wapadera laser kusungunuka ndi quenching zokutira akhoza anakonza kuchepetsa kwambiri roughness pamwamba pa wosanjikiza anasungunuka. Pamwamba roughness a masikono ndi workpieces zina za zipangizo zosiyanasiyana mu makampani zitsulo kuti panopa akudwala laser kusungunuka mankhwala ali pafupi mlingo wa laser quenching. Kuzimitsa kwa laser kwagwiritsidwa ntchito bwino pakulimbitsa thupi kwa zida zamakina opanga zitsulo, mafakitale amakina, ndi mafakitale a petrochemical. Makamaka pakusintha moyo wautumiki wovala zida monga zodzigudubuza, akalozera, magiya, ndi lumo, zotsatira zake ndi zodabwitsa ndipo zopambana zachitika. Lapeza phindu lalikulu lazachuma ndi chikhalidwe cha anthu. M'zaka zaposachedwa, yakhala ikugwiritsidwa ntchito kwambiri pakulimbitsa zinthu zapamtunda monga nkhungu ndi magiya. Ukadaulo wozimitsa wa laser ndi njira yomwe imagwiritsa ntchito mtengo wokhazikika wa laser kuti itenthetse mwachangu pamwamba pazida zachitsulo, ndikupangitsa kuti isinthe magawo ndikupanga wosanjikiza wozimitsa wa martensite. Ndikukhulupirira kuti zomwe zatulutsidwa lero zingakuthandizeni.

Laser quenching makamaka ntchito pochiza chitsulo-based zipangizo. Njira yake yayikulu ndikusanthula pamwamba pa chogwirira ntchito ndi mtengo wamagetsi wamagetsi wamagetsi. Pamwamba zinthu workpiece zimatenga laser cheza mphamvu ndi kuwasandutsa kutentha mphamvu. Kenaka, kupyolera mu kuyendetsa kutentha, kutentha kwa zinthu zozungulira kumawonjezeka mofulumira kwambiri. Pamwamba pa kusintha kwa gawo la austenite ndi pansi pa malo osungunuka, kupyolera mwa kudziletsa kuzizira kwa masanjidwe azinthu, zinthu zotentha pamtunda zimakhazikika mofulumira pamlingo woposa kuzizira kwakukulu kwa kusintha kwa gawo la martensite, ndiyeno kusinthika kwa gawo kumatsirizika. Chifukwa cha kuchuluka kwa kutentha kwakukulu komanso kuzizira kwambiri panthawi yozimitsa laser, njere za wosanjikiza zimakhala zabwino kwambiri, kachulukidwe kameneka kamakhala kokwezeka kwambiri, ndipo kupsinjika kumapangidwa pamwamba, zomwe zimatha kusintha kwambiri kukana kuvala, kukana kutopa. , kukana dzimbiri, ndi kukana dzimbiri kwa workpiece. Anti-oxidation ndi ntchito zina zimakulitsa moyo wautumiki wa workpiece. Ubwino wa laser quenching:

1. Zigawo zozimitsa laser sizimapunduka. The matenthedwe mkombero ndondomeko laser quenching ndi mofulumira. Chitsulo chapakati cha carbon. Masamba akuluakulu.

2. Pafupifupi palibe kuwonongeka kwa roughness pamwamba. Gwiritsani ntchito anti-oxidation chitetezo zokutira zopyapyala. Chitsulo cha nkhungu. Mitundu yosiyanasiyana.

3. Laser kuzimitsa popanda kusweka Zolondola ndi kuchuluka CNC kuzimitsa Cold ntchito nkhungu zitsulo Zimaumba ndi kudula zida

4. Kuzimitsidwa kwa zigawo, ngalande, ndi poyambira CNC kuzimitsa ndi malo olondola Medium carbon aloyi zitsulo Kugwedera absorber

5. Kuzimitsa kwa laser ndi koyera komanso kothandiza ndipo sikufuna sing'anga yozizira. Zida zachitsulo. Masilinda a injini.

6. The quenching kuuma ndi apamwamba kuposa ochiritsira njira. Chotsitsa chozimitsa chimakhala ndi mawonekedwe abwino komanso mphamvu yabwino komanso kulimba. High carbon alloy steel. Mpukutu waukulu.
