Kubwezeretsa moyo wa nkhungu pogwiritsa ntchito njira zopangira zinthu mwanzeru: Kuphimba ndi laser kwayambitsa nthawi yatsopano yopanga nkhungu yapamwamba

Mu makampani opanga magalimoto omwe akupikisana kwambiri, thanzi ndi magwiridwe antchito a nkhungu zimatsimikiza mwachindunji mtundu wa zida zosindikizidwa, magwiridwe antchito a mizere yopangira, komanso mtundu womaliza wa magalimoto. Poyang'anizana ndi kutsekedwa ndi kuchotsedwa kwa nkhungu chifukwa cha kuwonongeka, mikwingwirima, ndi dzimbiri, kodi mukukumana ndi mavuto otsatirawa?

Kupanga nkhungu zatsopano ndi kokwera mtengo komanso nthawi yayitali?

Kodi kuwotcherera kwachikhalidwe kumataya kulondola ndi malo osalala, zomwe zimafuna kupukutidwa kwambiri ndi manja?

Kodi nthawi ya nkhungu si yofanana ndi momwe amayembekezera ndipo kusintha nthawi zambiri kumabweretsa kukwera kwa ndalama zopangira?

Tsopano, njira yothetsera mavuto yakula - njira yolumikizirana ya 'kukonza matrix yolumikizira + kulimbitsa molondola kwa laser cladding'. Izi sizimangokonza zokha, komanso ndalama zoyendetsera bwino ntchito ya nkhungu, ndipo ukadaulo wa laser cladding ndiye chinsinsi chowonjezera kawiri mtengo wa nkhungu.

I. Kuphatikiza Kwagolide: Unyolo Wabwino Wokonzanso Wamphamvu ndi Wosinthasintha

Gawo 1: Kulukira Maziko - Kulimbitsa Umphumphu wa Kapangidwe ka Nkhungu

Pa zolakwika zazikulu, ming'alu kapena kutayika kwa mawonekedwe pa nkhungu, choyamba timagwiritsa ntchito njira yowotcherera yogwira ntchito kwambiri kuti tidzaze ndikumanganso. Gawo ili lili ngati "kumanganso mafupa", cholinga chake ndi kubwezeretsa kapangidwe kake ka macro geometric ndi mphamvu yonse ya nkhungu, ndikupereka maziko olimba komanso okhazikika kuti tigwiritse ntchito molondola.

Gawo 2: Kumaliza kwa laser cladding - kupanga 'malo apamwamba kwambiri' a nkhungu

Nthawi imene ukadaulo wathu waukulu—kuphimba ndi laser—umayamba kuonekera pa chinthu cholimba cholumikizidwa. Iyi si njira yachilendo yophikira; imagwiritsa ntchito kuwala kwa laser kwamphamvu kwambiri kuti isungunule nthawi yomweyo ufa wapadera wa alloy womwe mwasankha (monga cobalt-based, nickel-based, kapena metal-ceramic composites), nthawi yomweyo imapanga mgwirizano wolimba wa zitsulo ndi chinthu chopangidwa ndi nkhungu.

Kukongola kwa njirayi ndi:

Kuwongolera kolondola: Mpeni wa laser uli ngati "mpeni woduladula pang'ono", womwe ungapangitse kuti utoto woonda kwambiri wa 0.1-2mm ukhale woonda kwambiri, kubwezeretsa mosavuta kulondola kwa mawonekedwe a nkhungu, ndikuchepetsa kwambiri kapena kuchotsa njira yotopetsa yopera molondola pambuyo pake.

Kudumpha kwa magwiridwe antchito: Chophimbacho chimapereka kuuma pamwamba kuposa chitsulo cha nkhungu (mpaka HRC 60+), kuuma kochepa kwambiri, komanso kukana bwino kuwonongeka ndi dzimbiri.

Malo osalala: kapangidwe ka chipinda cholumikizira ndi kolimba komanso kofanana, komwe kumatha kupangitsa kuti malo osalala akhale osalala kwambiri, kuthetsa mavuto a ma pores ndi ma pockmarks pambuyo pa kuwotcherera kwachikhalidwe, ndikukweza mwachindunji mawonekedwe a pamwamba pa zinthu zosindikizidwa.

II. N’chifukwa chiyani tiyenera kusankha njira yathu yolumikizirana ndi laser? Mtengo wake ndi wodziwikiratu

Kuphatikiza makina athu opangira ma laser mu njira zanu zopangira ndi kukonzanso nkhungu kumatanthauza kuti mudzapindula ndi izi:

1. Kusintha kwa kayendetsedwe ka nkhungu kuchoka pa "zogwiritsidwa ntchito" kupita ku "katundu"
Chikombolecho sichilinso gawo logwiritsidwa ntchito lomwe liyenera kusinthidwa nthawi zonse. Kudzera mu laser cladding reinforcement, moyo wa ntchito ya pamwamba pa ntchito ukhoza kuwonjezeka ndi nthawi 2-5, zomwe zimafalitsa mwachindunji ndalama zogulira chikole ku moyo wonse, ndikusunga ndalama zambiri kwa nthawi yayitali.

2. Kugwirizana kwa kulondola kwambiri ndi kugwira ntchito bwino kwambiri
"Kukhazikitsa kamodzi, kumaliza magawo awiri." Kugwira ntchito kogwirizana kwa kuwotcherera ndi kuphimba kumachotsa zolakwika zoyikira zomwe zimachitika chifukwa cha kusokoneza ndi kusonkhanitsa mobwerezabwereza. Ukadaulo wopanga mawonekedwe a neti wa laser cladding umakumasulani ku kupukuta kosasangalatsa ndi kuyeza mobwerezabwereza, kuchepetsa nthawi yokonza ndi 70% ndikupangitsa kuti nkhungu zibwerere ku mizere yopangira mwachangu.

3. "Konzani zakale, osati zatsopano" —— Magwiridwe antchito opitilira kapangidwe koyambirira

Mungathe kusintha zinthu zoyenera kwambiri zophimba nkhungu pansi pa mikhalidwe inayake yopangira (monga mbale zachitsulo zolimba kwambiri kapena aluminiyamu). Izi zikutanthauza kuti nkhungu zokonzedwazo zipambana zatsopano pamlingo wofunikira kwambiri, zomwe zimawathandiza kuthana ndi mikhalidwe yovuta yogwirira ntchito pomwe akupereka magwiridwe antchito abwino komanso mtundu wabwino wa zinthu.

4. Yambitsani zinthu zomwe zilipo kale

Zinyalala zakale komanso zakale zomwe zili mu workshop, zomwe "sizikoma kudya koma zamtengo wapatali kwambiri kuti zitayidwe", ndi "mgodi wagolide" womwe ukuyembekezera kukumba. Ukadaulo wathu ukhoza kuwapangitsa "kubadwanso" ndikukhala ndi "thupi lamphamvu", zomwe zimapangitsa kuti katundu wanu akhale wofunika kwambiri.

III. Gwirizanani manja kuti mupange tsogolo la kukonzanso nkhungu mwanzeru

Tikumvetsa kuti seti iliyonse ya nkhungu imagwirizana kwambiri ndi kamvekedwe ka mzere wanu wopanga. Sitimapereka zida ndi zipangizo zapamwamba zokha, komanso yankho lathunthu la kukulitsa moyo wa nkhungu ndikuwongolera magwiridwe antchito, kuphatikiza chitukuko cha njira, maphunziro aukadaulo, ndi ntchito yopitilira yogulitsa pambuyo pogulitsa.

Chitanipo kanthu tsopano, tiyeni tichite limodzi:

Sinthani mtengo wokwera wosinthira nkhungu kukhala ndalama zogwirira ntchito bwino.

Sinthani zoopsa zosayembekezereka za nthawi yopuma kukhala mapulani opanga zinthu okhazikika komanso osinthika.

Sinthani nkhungu wamba kukhala zida zofunika kwambiri kuti muwonetsetse kuti zinthu zili bwino komanso kuti msika ukhale wopikisana.

Tiyeni tigwirizane, ndi kuwala kwa laser, kuti tiphimbe nkhungu yanu ndi "unyamata" wosatha, ndikupita ku tsogolo la kupanga zinthu mwanzeru!
