Ukuvuselela impilo yesikhunta ngokukhiqiza okuhlakaniphile: Ukufakwa kwe-laser kuphayona inkathi entsha yokukhiqizwa kwesikhunta okuthuthukisiwe
Embonini yokukhiqiza izimoto encintisana kakhulu, isimo sempilo kanye nokusebenza kwesikhunta kunquma ngqo ikhwalithi yezingxenye ezigxiviziwe, ukusebenza kahle kwemigqa yokukhiqiza, kanye nekhwalithi yokugcina yezimoto. Uma ubhekene nokuvalwa nokukhuhla kwesikhunta ngenxa yokuguga, imihuzuko, kanye nokugqwala, ingabe ubhekene nalezi zindawo ezilandelayo ezibuhlungu?
Ukukhiqizwa kwesikhunta esisha kuyabiza futhi kuthatha isikhathi eside?
Ukushisela kwendabuko kulahlekelwa ukunemba kanye nobuso obuqinile, okudinga ukugaya okuningi ngesandla?
Ingabe impilo yesikhunta ayinjengoba ilindelwe futhi ukushintshwa njalo kuholela ekukhuphukeni kwezindleko zokukhiqiza?
Manje, ikhambi eliphazamisayo selivuthiwe - inqubo ehlanganisiwe 'yokulungisa i-welding matrix + ukuqinisa ukuchaneka kwe-laser cladding'. Lokhu akusikho nje ukulungisa, kodwa kuyindlela yokutshala imali ehlelekile ekusebenzeni kwesikhunta, futhi ubuchwepheshe be-laser cladding buyisihluthulelo sokuphinda kabili inani lesikhunta.
I. Inhlanganisela Yegolide: Uchungechunge Oluphelele Lokulungisa Lwamandla Nokuguquguquka
Isinyathelo 1: Ukushisela Isisekelo – Ukuqinisa Ubuqotho Besakhiwo Sesikhunta
Uma kukhona amaphutha amakhulu, imifantu noma ukulahlekelwa okukhulu kwesikhunta, siqala sisebenzisa inqubo yokushisela esebenza kahle kakhulu ukugcwalisa nokwakha kabusha. Lesi sinyathelo sifana "nokwakhiwa kabusha kwamathambo", sihlose ukubuyisela isakhiwo sejometri enkulu kanye namandla aphelele esikhunta, futhi sinikeze isisekelo esiqinile nesizinzile sokwelashwa okunembile okulandelayo.
Isinyathelo 2: Ukuqeda ukumbozwa nge-laser – ukudala 'indawo ethambile kakhulu' yezibunjwa
Isikhathi lapho ubuchwepheshe bethu obuyinhloko—ukumbozwa nge-laser—buthola ukukhanya kwaso sivela phezu kwe-substrate eqinile ehlanganisiwe. Lena akuyona inqubo evamile yokumboza; isebenzisa imisebe ye-laser enamandla aphezulu ukuze incibilikise ngokushesha izimpushana zakho ezikhethekile ze-alloy (ezifana nezinhlanganisela ezisekelwe ku-cobalt, ezisekelwe ku-nickel, noma zensimbi-ceramic), ngasikhathi sinye zakha isibopho esiqinile se-metallurgical ne-substrate yesikhunta.
Ubuhle bale nqubo yilokhu:
Ukulawula okunembile: Ugongolo lwe-laser lufana "nommese oqoshiwe omncane", ongafinyelela ungqimba oluncane kakhulu lwe-0.1-2mm, ubuyisele kalula ukunemba kwephrofayili yokuqala yesikhunta, futhi unciphise kakhulu noma uqede inqubo eyisicefe yokugaya ngokunemba kamuva.
Ukugxuma kokusebenza: Isendlalelo sokumboza sinikeza ubulukhuni bomphezulu obudlula kakhulu obensimbi yokubumba ngokwayo (kufika ku-HRC 60+), i-coefficient ephansi kakhulu yokungqubuzana, kanye nokumelana okuhle kakhulu nokuguguleka.
Ubuso obubushelelezi: isakhiwo sesendlalelo sokumboza siminyene futhi sifana, esingathola ngqo ukushelela okuphezulu kobuso, sixazulule ngempumelelo izinkinga zama-pores nama-pockmark ngemva kokushisela kwendabuko, futhi sithuthukise ngqo ikhwalithi yobuso bezingxenye ezigxiviziwe.
II. Kungani kufanele ukhethe ikhambi lethu le-laser cladding? Inani lisobala
Ukuhlanganisa uhlelo lwethu lokubopha nge-laser ezinqubweni zakho zokukhiqiza nokuvuselela isikhunta kusho ukuthi uzothola izinzuzo zalokhu:
1. Uguquko ekuphathweni kwesikhunta kusuka "kokusetshenziswayo" kuya "empahleni"
Isikhunta asiseyona ingxenye esetshenziswayo edinga ukushintshwa njalo. Ngokuqiniswa kwe-laser cladding, impilo yesevisi yendawo yokusebenza eyinhloko ingandiswa ngokuphindwe kabili kuya kahlanu, okusabalalisa ngokungaqondile izindleko zokuthenga isikhunta kuwo wonke umjikelezo wokuphila, futhi kufezwe ukonga okukhulu kwezindleko zesikhathi eside.
2. Ubunye bokunemba okukhulu kanye nokusebenza kahle okukhulu
"Ukusetha okukodwa, ukuqedwa kwezinyathelo ezimbili." Ukusebenza okuhlanganisiwe kokushisela kanye nokumboza kususa amaphutha okubeka abangelwa ukuhlukaniswa nokuhlanganiswa okuphindaphindiwe. Ubuchwepheshe bokwakha ukuma kwe-laser cladding obuseduze nenethi bukukhulula ekugayweni ngesandla okukhathazayo kanye nokulinganisa okuphindaphindiwe, kunciphisa imijikelezo yokulungisa ngamaphesenti afinyelela ku-70 futhi kuvumela isikhunta ukuthi sibuyele emigqeni yokukhiqiza ngokushesha.
3. "Lungisa okudala, hhayi okusha" —— Ukusebenza okungaphezu komklamo wokuqala
Ungakwazi ngisho nokwenza ngokwezifiso izinto zokumboza ezifanele kakhulu zezikhunta ngaphansi kwezimo ezithile zokukhiqiza (njengezingcwecwe zensimbi ezinamandla aphezulu noma ama-aluminium alloys). Lokhu kusho ukuthi izikhunta ezilungisiwe zizosebenza kangcono kunezintsha ngezilinganiso zokusebenza ezibalulekile, okuzenza zikwazi ukubhekana nezimo zokusebenza ezidinga kakhulu ngenkathi ziletha ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo.
4. Sebenzisa izimpahla ezikhona
Izikhunta eziphelelwe yisikhathi neziphelelwe yisikhathi eshabhu, "ezingenambitheki ukuthi zingadliwa kodwa ezibaluleke kakhulu ukuthi zingalahlwa", "zimayini zegolide" ezilindele ukumbiwa. Ubuchwepheshe bethu bungenza "zizalwe kabusha" futhi zibe "nomzimba oqinile", okwandisa inani lempahla yakho ekhona.
III. Bambisanani ukuze nidale ikusasa lokukhiqiza kabusha isikhunta ngobuhlakani
Siyaqonda ukuthi yonke isethi yesikhunta ihlobene kakhulu nesigqi somugqa wakho wokukhiqiza. Asinikezi nje kuphela imishini nezinto zokwakha ezithuthukisiwe ze-laser, kodwa futhi nesixazululo esiphelele sokwandiswa kokuphila kwesikhunta kanye nokuthuthukiswa kokusebenza, okuhlanganisa ukuthuthukiswa kwenqubo, ukuqeqeshwa kobuchwepheshe, kanye nensizakalo eqhubekayo yangemva kokuthengisa.
Thatha isinyathelo manje, ake sikwenze ndawonye:
Guqula izindleko eziphezulu zokushintsha isikhunta zibe utshalomali olusebenzayo oluphumelelayo.
Guqula izingozi ezingalindelekile zesikhathi sokungasebenzi zibe izinhlelo zokukhiqiza ezizinzile nezilawulekayo.
Thuthukisa izikhunta ezivamile zibe amathuluzi ayinhloko ukuqinisekisa ikhwalithi yomkhiqizo kanye nokuncintisana emakethe.
Masihlangane ngezandla, ngokukhanya kwe-laser, ukuze simboze isikhunta sakho "ngobusha" baphakade, bese sihamba siye ekusaseni lokukhiqiza okuhlakaniphile!
