Izibonelo eziningiliziwe ze-Shaft Machining Technology

Ukuphendula izidingo ezingenhla, okulandelayo kuyisibonelo. Uthi lokuphotha (oluboniswe ngenhla), izingcezu ezingama-40 ngeqoqo ngalinye, okokusebenza okungu-20Cr, ngaphandle kwemicu yangaphakathi nangaphandle engu-S0.9 ~ C59. Inqubo ye-carburizing inzima kakhulu, futhi umdwebo wenqubo kumele udwetshwe ngenqubo yokuganga (okufanekiselwa).

Ukwakhiwa kokucaciswa kwenqubo ezingxenyeni ze-shaft kuhlobene ngqo nekhwalithi yomsebenzi, ukukhiqizwa kwabasebenzi kanye nezinzuzo zezomnotho.

Ingxenye ingaba nezindlela zokucubungula ezahlukahlukene, kepha yinye kuphela yazo enengqondo kakhulu. Ekubunjweni kwe- inqubo machining incazelo, amaphuzu alandelayo kufanele aqashelwe.

• 1.Ekuhlaziyweni kwenqubo yezingxenye zokudweba, kuyadingeka ukuqonda izidingo zobuchwepheshe zezici zesakhiwo, ukucacisa, okokusebenza, ukwelashwa kokushisa, njll, nokufunda umdwebo womhlangano womkhiqizo, umdwebo womhlangano wezinto kanye nenqubo yokwamukela.
• 2.Umzila wokucubungula wezingxenye ze-carburizing ngokuvamile: ukusika → UKWAKHA → ukujwayela → ukujija → ukuqeda semi → ukuqeda ukukhishwa kwekhabhoni (engxenyeni engadingi ukuthuthukisa ubulukhuni) → ukucima → ukuchusha, ukubhola noma ukugaya iGroove → ukugaya okunamandla → ukuguga okushisa okuphansi → ukuqeda okuncane → ukuqeda izinga lokushisa eliphansi → ukuqeda.
• 3.Ukukhethwa kwesithenjwa esibi: Uma kukhona indawo engenamishini, indawo engeyona imishini kufanele ikhethwe njengereferensi enokhahlo. Okwenziwe izimbazo okudingeka kwenziwe ngomshini kuzo zonke izindawo, indawo encane ilungiswa ngokuvumelana nesabelo semishini. Futhi ukhethe indawo ebushelelezi, vumela isango. Khetha indawo eqinile nethembekile njengesethenjwa esibi, kuyilapho ireferensi ekhululekile ingasetshenziswa kabusha.
• 4.Ukukhethwa kwesilinganiso esihle: ukuhlangabezana nomgomo wokuqondana okuyisisekelo, ngangokunokwenzeka ukukhetha isisekelo sokuklama noma ibenchmark yomhlangano njengebhentshi lokuma. Ngokuhambisana nomgomo wokumaka. Sebenzisa ireferensi efanayo yokuma ngangokunokwenzeka ekusebenzeni okuningi. Ngokusemandleni, ireferensi yokuma iqondane nesethenjwa sesilinganiso. Ukukhethwa kobuciko obuphezulu, obuzinzile futhi obunokwethenjelwa yisilinganiso esihle.

Okuvamile

Inqubo yokuqukethwe: ukuhlanza nokugcoba uwoyela olwa nokugqwala, isitoreji esime mpo silenga ku-workpiece

Amanye amaphuzu ekusetshenzisweni komshini kushaft:

• Imigodi emibili yesikhungo isetshenziswa njengereferensi yokuma, ehambisana nomgomo oshiwo ngenhla wenkomba yokuqondanisa kanye nokuma kwezilinganiso.
• 2.Ingxenye yokuqala isebenzisa umbuthano wangaphandle njengesethenjwa esibi, ubuso bokugcina bemoto nomgodi ophakathi nendawo wokuprakthiza, bese isiyingi sangaphandle semoto esime kahle sinezimbobo zombili zesikhungo njengereferensi yokuma, futhi imbobo ye-taper icutshungulwa ngombuthano wangaphandle wemoto enjengesithenjwa sokuma, okuyisimiso senkomba efanayo. Imishini ine-datum yokuma enembile kakhulu kunangesikhathi esisodwa. Cha. 3 Izidingo zokunemba kwesigaxa se-Mohs ziphakeme kakhulu. Ngakho-ke, isakhiwo esenziwe ngo-V siyadingeka ukufeza imfuneko yokubekezelelana kwejometri nombuthano wangaphandle we-2-ф30js5 njengesethenjwa sokuma. Lapho isigaxa singaphakathi emotweni, uhlangothi olulodwa lubhajwe ngozipho, bese kuthi uhlangothi olulodwa lugxile ohlakeni oluphakathi nendawo, futhi isiyingi sangaphandle sisetshenziswa futhi njengesethenjwa esihle.
• 3. Lapho kuqedwa futhi kuqedwa isiyingi esingaphandle, kusetshenziswa ipulaki lesigaxa, futhi imbobo emaphakathi yesigaxa isetshenziswa njengereferensi yokuma yokuqedela indawo engaphandle eyisiyingi.

Ngezidingo zokufaka izigaxa:

• Ipulaki le-1.Cone linokunemba okuphezulu, okuqinisekisa ukuthi indawo yokuthinta iplagi yesigaxa inezinga eliphakeme lokugxila nomgodi wayo wethiphu.
• I-plug ye-cone akufanele ithathelwe indawo ngemuva kokufakwa ukunciphisa iphutha lokufaka elidalwe ukufakwa okuphindaphindwayo.
• 3. Ububanzi bangaphandle bobubanzi obungaphandle bepulaki lesigaxa kufanele benziwe ngasekupheleni komphetho ukuze kususwe futhi kususwe isigaxa.
• I-4 imishini shaft i-carburized futhi iqine insimbi engu-20Cr low-carbon alloy, futhi into yokusebenza ayidingeki ukuthi iqine (M30 × 1.5-6g kwesokunxele, M30 × 1.5-6g, M12-6H, M6-6H), kusale ukususwa kwekhabhoni okungu-2.5-3mm ungqimba ebusweni. .
• 5.After intambo icishiwe, ayikwazi ukucutshungulwa ku-lathe. Uma intambo iqale yajijwa bese icinywa, intambo izokhubazeka. Ngakho-ke, intambo ngokuvamile ayikuvumeli ukuqina, ngakho-ke ungqimba lwekhabhoni kufanele lushiywe kububanzi nobude besabelo esinezintambo ku-workpiece. Kwemicu yangaphakathi, ungqimba we-3 mm decarburization nawo kufanele ushiywe ku-orifice.
• 6.Ukuze kuqinisekiswe ukunemba komgodi wesikhungo, umgodi ophakathi nendawo yokusebenza awuvunyelwe ukuba uqine. Ngalesi sizathu, ubude bento engenalutho bungu-6 mm.
• 7.Ukuze uqinisekise ukunemba kokugaya kombuthano wangaphandle womsebenzi, inqubo yokugaya imbobo yesikhungo kufanele ihlelwe ngemuva kokwelashwa kokushisa, futhi kudingeka indawo enobuso obuhle. Lapho indingilizi yangaphandle ingumhlabathi, ukuzungeza okuthinta okokusebenza ikakhulukazi kungenxa yobumbano lwezimbobo ezimbili eziphezulu nephutha lokuzungeza lomgodi ophezulu.
• 8.Ukuze uqede ukucindezela kokugaya, inqubo yokuguga yokushisa okuphansi (ukubhaka) ihlelwe ngemuva kokugaya okunzima.
• 9.Ukuze uthole umbuthano ongaphandle wokunemba okuphezulu, ukugaya kufanele kuhlukaniswe kube ukugaya okunokhahlo, ukuqeda semi, nokugaya okuhle. Ukugaya okuhle kuhlelwe kumshini wokugaya ophakeme kakhulu.
