Ukadaulo wa laser cladding ndi wothandiza kwambiri pakukonza mota

Pa nthawi yokonza ndi kukonza ma mota, ziwalo nthawi zambiri zimakhala zosayenerera chifukwa cha ntchito yayitali, kuwonongeka, kapena kusakanizidwa bwino. Mwachitsanzo, mpando woperekera bere wa shaft ya mota umakhala wochepa chifukwa cha kuwonongeka, ndipo chipinda choperekera bere chimakula chifukwa cha kumasuka. Pa mayunitsi okonza ndi kukonza akatswiri, ukadaulo wokonzanso wakomweko ndi wofunikira kwambiri chifukwa satha kukonza ndikusintha ziwalo zonse. Njira zokonzera zachikhalidwe monga kupukutira burashi, pamwamba, ndi kuwotcherera kozizira zimagwiritsidwa ntchito kwambiri, koma chilichonse chili ndi zofooka zake. M'zaka zaposachedwa, ukadaulo wopaka laser wakhala ukugwiritsidwa ntchito kwambiri pantchito yokonza zigawo zamagalimoto chifukwa cha magwiridwe ake abwino okonzanso komanso kusinthasintha kwa njira. Nkhaniyi ifotokoza mwatsatanetsatane mfundo, mawonekedwe a njira, ubwino, ndi kugwiritsa ntchito ukadaulo wopaka laser pakukonza magalimoto.

1. Makhalidwe a njira yopangira laser cladding

Ukadaulo wa laser cladding ukhoza kugawidwa m'mitundu iwiri: synchronous powder feeding cladding ndi pre-set powder cladding, kutengera njira yogwirira ntchito. M'zaka zaposachedwapa, kubuka kwa ukadaulo wa ultra-high-speed laser cladding (EHLA) kwapititsa patsogolo magwiridwe antchito ndi ubwino wa njirayi.

Kuphimba kwa Laser Kwachizolowezi vs. Kuphimba kwa Laser Kwachangu Kwambiri

Chophimba cha laser chothamanga kwambiri chingapangitse kuti chikhale chofanana chifukwa cha dziwe lake losungunuka kwambiri komanso kuzizira mwachangu kwambiri, ndipo chimakhala ndi mphamvu zochepa pa substrate, zomwe zingapewe kusintha kwa ntchito. Ndi choyenera kwambiri kukonza malo olumikizirana molondola monga ma bearing a mota ndi ma journal.

2. Kugwiritsa Ntchito Kwachizolowezi kwa Laser Cladding Pokonza Magalimoto

Mu ntchito yokonza magalimoto, ukadaulo wa laser cladding umagwiritsidwa ntchito makamaka pazochitika zotsatirazi:

1) Kukonza mabearing a mota

Pambuyo pa ntchito yayitali, ma bearing a ma motor shaft nthawi zambiri amachepa kukula chifukwa cha kuwonongeka. Njira zachikhalidwe monga brush plating kapena thermal spray zimakhala ndi mphamvu yochepa yolumikizira, pomwe cladding imayambitsa kusintha mosavuta. Laser cladding imatha kuvala molondola zinthu zolimba kwambiri (monga nickel-based alloys kapena cobalt-based alloys) pazinthu zosweka, kubwezeretsa kukula ndikuwonjezera kukana kuwonongeka.

2) Kukonza kuvala kwa chipinda chosungiramo zinthu

Chipinda chonyamulira chimakhala chachikulu chifukwa cha kutayikira kwa mabearing kapena kusakanizidwa bwino. Njira zachikhalidwe monga kuyika manja kapena cladding zimakhala ndi nthawi yayitali yokonzanso komanso mtengo wake ndi wokwera. Kuphimba kwa laser kumatha kuphimba mwachindunji gawo lachitsulo pamwamba pake, kenako ndikubwezeretsa kukula koyambirira kudzera mu makina opangidwa bwino, zomwe zimafupikitsa kwambiri nthawi yokonza.

3) Kukonza kuwonongeka kwa malo osungiramo zinthu zakale, msewu waukulu, ndi zina zotero.

Chojambulira cha injini, keyway, ndi zina zotero zingawonongeke m'deralo chifukwa cha kugwedezeka kapena kutopa. Kuphimba ndi laser kumatha kuzikonza molondola, kupewa kufunikira kosintha ziwalo zonse za shaft ndikuchepetsa ndalama.

3. Ubwino wa laser cladding kuposa njira zachikhalidwe zokonzera

Poyerekeza ndi njira zachikhalidwe zokonzera (monga kuwotcherera pamwamba, kuyika maburashi, ndi kuwotcherera kozizira), kuphimba ndi laser kumapereka zabwino zotsatirazi:

Mphamvu Yaikulu Yogwirizanitsa: Kugwirizana kwa zitsulo kumatsimikizira mgwirizano wolimba pakati pa cladding wosanjikiza ndi substrate, zomwe zimapangitsa kuti isachotsedwe.

Mphamvu Yotsika ya Kutentha: Kutentha kochepa kumachepetsa kusintha kwa substrate, zomwe zimapangitsa kuti ikhale yoyenera kwambiri kukonza zigawo zolondola.

Kugwirizana kwa Zinthu Zambiri: Imatha kuphimba zinthu zosiyanasiyana, kuphatikizapo chitsulo chosapanga dzimbiri, zitsulo zopangidwa ndi nickel, ndi tungsten carbide, kuti ikwaniritse ntchito zosiyanasiyana.

Kukonza Kwambiri Mwachangu: Kuwongolera kwa micron-level kumachitika, zomwe zimachepetsa ntchito zochizira pambuyo pake.

Yogwirizana ndi chilengedwe komanso yogwira ntchito bwino: Palibe kuipitsa kwa magetsi, ufa wambiri umagwiritsidwa ntchito, komanso imagwirizana ndi njira zopangira zinthu zobiriwira.

4. Zofooka ndi Zochitika Zamtsogolo Za Chitukuko cha Laser Cladding

Ngakhale kuti ukadaulo wa laser cladding uli ndi ubwino waukulu, udakali ndi zofooka zina:

Mtengo Wapamwamba wa Zipangizo: Makina ophimba a laser ndi okwera mtengo, zomwe zimapangitsa kuti zida zokonzera zizikhala zofunika kwambiri.

Zofunikira pa Njira Yogwirira Ntchito: Magawo a laser ayenera kuyendetsedwa bwino, apo ayi zolakwika monga ma porosity ndi ming'alu zingachitike.

Zoletsa Kukula: Kukonza zinthu zazikulu kwambiri (monga ma rotor olemera) kumadalirabe njira zachikhalidwe.

Mtsogolomu, chifukwa cha kugwiritsa ntchito kwambiri zida zanzeru zophimba ma laser komanso kuphatikiza kwake ndi ukadaulo wokonzanso zosindikizira za 3D, chophimba ma laser chidzagwiritsidwa ntchito kwambiri pokonza magalimoto ndipo chingakhale ukadaulo wofunikira kwambiri popanganso magalimoto.

5. Mapeto

Ukadaulo wa laser cladding, wokhala ndi kulondola kwake kwakukulu, kutentha kochepa, komanso mphamvu zabwino zomangira, ukuwonetsa kuthekera kwakukulu kokonzanso zigawo zamagalimoto. Poyerekeza ndi kuwotcherera kwachikhalidwe ndi burashi, umabwezeretsa bwino miyeso yosweka ndikuwonjezera kukana kwa dzimbiri kwa zigawo. Ngakhale kuti pali mitengo yokwera ya zida komanso zopinga za njira, ndi kupita patsogolo kwaukadaulo, laser cladding ikuyembekezeka kukhala yankho lofunikira kwambiri pakukonza magalimoto, kupereka chitsimikizo chodalirika cha magwiridwe antchito a mota kwa nthawi yayitali komanso okhazikika.
