Uma kwakheka kudayi eqhubekayo, ingcindezi yesibambi esingenalutho, izimo zengcindezi, kanye nezinto zokusetshenziswa konke kuthinta ikhono lokuthola imiphumela yokwelula ehambisanayo ngaphandle kokushwabana.
U: Sidonsa izinkomishi ngensimbi engagqwali yebanga lama-304. Esitobhini sokuqala sedayi yethu eqhubekayo, sidonsa cishe amasentimitha angu-0.75 ukujula. Uma ngihlola ubukhulu bomphetho we-flange wesikhala, umehluko kusukela ohlangothini kuya kolunye ungaba amasentimitha angu-0.003. Ukushaya ngakunye kuhlukile futhi akuveli endaweni efanayo. Ngitshelwe ukuthi kuhlobene nokucutshungulwa kwezinto zokusetshenziswa, mhlawumbe umkhawulo wangaphandle wekhoyili eyinhloko. Singayithola kanjani indebe enomumo ohlala njalo ngaphandle kokushwabana?
A: Ngiyabona ukuthi umbuzo wakho uphakamisa imibuzo emibili: okokuqala, izinguquko ozitholayo enkambisweni yelotho, kanti okwesibili, izinto zokusetshenziswa kanye nemininingwane yazo.
Umbuzo wokuqala uphathelene namaphutha ayisisekelo okuklama amathuluzi, ngakho-ke ake sibukeze izisekelo. Ukushwabana okungapheli kanye nokushintsha kobukhulu ngemuva kokudweba kuma-flange endebe kubonisa ukunganele kwezikhala zamathuluzi esiteshini sakho sokudweba nge-die esiqhubekayo. Ngaphandle kokubona umklamo wakho we-die, kuzodingeka ngicabange ukuthi i-draw punch yakho ne-die radii yakho kanye nezikhala zazo zihlangabezana nazo zonke izilinganiso zokuklama ezijwayelekile.
Ekudwebeni okujulile, isikhala sibanjwa phakathi kwedayi yokudweba kanye nesiphathi esingenalutho, kuyilapho isipikha sokudweba sidonsela izinto kudayi yokudweba, sizidwebe sizungeze irediyasi yokudweba ukuze sakhe igobolondo. Kunokungqubuzana okuningi phakathi kwedayi kanye nesiphathi esingenalutho. Phakathi nale nqubo, izinto zicindezelwa eceleni, okuyimbangela yokuminyana kanye nokwelulwa kwe-radial kwesiphathi esingenalutho ngokumelene nokugeleza kwezinto. Uma ingcindezi yokubamba iphezulu kakhulu, izinto zizophuka ngaphansi kokudonsa kwesipikha sokunwebeka. Uma iphansi kakhulu, kuzokwenzeka imibimbi.
Kukhona umkhawulo phakathi kobubanzi begobolondo nobubanzi obungenalutho obungenakudlulwa ukuze kusetshenziswe ngempumelelo ukudweba. Lo mkhawulo uyahlukahluka ngokwezinga lobude bezinto ezibonakalayo. Umthetho ojwayelekile uphakathi kuka-55% kuya ku-60% kokudweba kokuqala kanye no-20% kokudweba ngakunye okulandelayo. Umfanekiso 1 uyifomula ejwayelekile yokubala ingcindezi yesibambi esingenalutho edingekayo ukuze kwelulwe (ngihlala ngengeza okungenani amandla engeziwe angu-30% njengesici sokuphepha, singancishiswa uma kudingeka, kodwa kunzima ukukhuphula ngemva kokuba umklamo usuqediwe).
Ingcindezi yesibambi esingenalutho p ingu-2.5 N/mm2 yensimbi, 2.0 kuya ku-2.4 N/mm2 yezinsimbi zethusi kanye no-1.2 kuya ku-1.5 N/mm2 yezinsimbi ze-aluminium.
Ukwehluka kobukhulu be-flange kubonisa nokuthi umklamo wamathuluzi akho awuqinile ngokwanele. Amabhuzu akho esikhunta kumele abe makhulu ngokwanele ukuze amelane nokudonswa ngaphandle kokugoba. Ukusekelwa ngaphansi kwesicathulo se-die kumele kube yinsimbi eqinile, kanti izikhonkwane zokuqondisa i-die kumele zibe nkulu ngokwanele ukuvimbela noma yikuphi ukunyakaza kwe-die ephezulu nephansi ngesikhathi sokwelula.
Hlola nezindaba zakho. Uma iziqondiso zokucindezela zigugile futhi zingahlelekile, akunandaba ukuthi ithuluzi lakho liqinile - ngeke uphumelele. Hlola islayidi yokucindezela ukuqinisekisa ukuthi ubude obugcwele bokucindezela buyiqiniso futhi buyisikwele. Qinisekisa ukuthi i-lubricant yakho yokudweba ihlungiwe kahle futhi inakekelwe, nokuthi inani lokusetshenziswa kwethuluzi kanye nendawo ye-nozzle kuzinzile. Hlola kahle wonke amathuluzi okuphrinta ukuqinisekisa ukuthi indawo iqediwe kahle, ukumbozwa, kanye nokulingana. Futhi unake kakhulu i-radii yokudweba; i-geometry yabo kanye nendawo yayo kumele kube okuphelele.
Futhi, yize amakhasimende evame ukubheka i-304L kanye ne-304 ejwayelekile njengezingashintshaniswa, i-304L iyindlela engcono yokudweba. I-L imele ikhabhoni ephansi, enikeza i-304L amandla okukhiqiza angu-0.2% we-35 KSI kanye no-304 we-0.2% we-42 KSI. Ngokuncipha kwe-16% kwamandla okukhiqiza, i-304L idinga amandla amancane okukhiqiza lapho yakha futhi ibeka isimo esakhiwe. Kulula ukuyisebenzisa.
