Lapho kwakheka kufa okuqhubekayo, ingcindezi yesibambi esingenalutho, izimo zengcindezi, nezinto ezingavuthiwe konke kuthinta ikhono lokuthola imiphumela yokwelula engaguquki ngaphandle kokushwabana.
Q: Sidweba izinkomishi zensimbi engagqwali yebanga elingu-304. Esitobhini sokuqala sokufa kwethu okuqhubekayo, sidonsela cishe amayintshi angu-0.75 ukujula. Uma ngibheka ukujiya kwepherimitha ye-flange yokungenalutho, umehluko ukusuka ohlangothini ukuya kwelinye ungaba amayintshi angu-0.003. Konke okushaywayo kuhlukile futhi akubonakali ekucubunguleni okuthile okutshelwe endaweni efanayo. unqenqema olungaphandle lwekhoyili eyinhloko.Singayithola kanjani inkomishi emise okwesikhathi eside ngaphandle kokushwabana?
IMP: Ngibona umbuzo wakho uphakamisa imibuzo emibili: okokuqala, izinguquko ozitholayo ohlelweni lwelotho, okwesibili, izinto zokusetshenziswa kanye nokucaciswa kwazo.
Umbuzo wokuqala uphathelene namaphutha ayisisekelo edizayini yamathuluzi, ngakho-ke ake sibuyekeze izinto eziyisisekelo.Ukushintsha kokushwabana okungapheli kanye nokushuba kwangemuva kokudweba kubonisa izikhala zamathuluzi ezinganele esiteshini sakho esiqhubekayo sokudweba.
Emdwebeni ojulile, okungenalutho kuhlanganiswe phakathi kwefa lomdwebo kanye nesibambi esingenalutho, kuyilapho i-punch yokudweba idonsa into efasiteleni lomdwebo, iyidwebe eduze kwendawo yokudonsa ukuze yakhe igobolondo. Kukhona ukungqubuzana okuningi phakathi kwefa kanye nesibambi esingenalutho. Phakathi nale nqubo, izinto ezisetshenziswayo zicindezelwa eceleni, okuyisizathu sokushwabana nokuphakama kwe-radial elongation ye-radial elongation ngokumelene nento engenalutho, uma ingcindezi ibamba ukuphakama kwento engenalutho. izophuka ngaphansi kokudonsa kwe-stretch punch.Uma iphansi kakhulu, ukushwabana kuzokwenzeka.
Kukhona umkhawulo phakathi kobubanzi begobolondo kanye nobubanzi obungenalutho obungeke budlulwe ukuze kwenziwe umsebenzi wokudweba ngempumelelo. Lo mkhawulo uyahlukahluka ngephesenti lokwelulwa kwezinto. Umthetho ovamile uwukuthi 55% kuya ku-60% ekudwebeni kokuqala kanye no-20% kumdwebo ngamunye olandelayo. okudingekayo, kodwa kunzima ukwanda ngemva kokuqedwa komklamo).
Ukucindezela kwesibambi esingenalutho p ngu-2.5 N/mm2 kwensimbi, 2.0 kuya ku-2.4 N/mm2 kuma-alloys ethusi kanye no-1.2 kuya ku-1.5 N/mm2 kuma-alloys e-aluminium.
Ukwehluka kogqinsi lwe-flange kuphinde kubonise ukuthi ithuluzi lakho eliklanywe ngalo aliqinile ngokwanele.Amabhuzu akho esikhunta kufanele abe aminyene ngokwanele ukuze amelane nokudonsa ngaphandle kokubopha.Ukwesekwa ngaphansi kwesisekelo se-die kumele kube insimbi eqinile, futhi izikhonkwane zegayidi yamathuluzi kufanele zibe zinkulu ngokwanele ukuvimbela noma yikuphi ukunyakaza kwe-lateral kwamathuluzi aphezulu naphansi ngesikhathi sokwelula.
Hlola izindaba zakho futhi.Uma imihlahlandlela yokushicilela igugile futhi inobudlabha, akunandaba ukuthi ithuluzi lakho liqinile - ngeke uphumelele.Hlola isilayidi sokushicilela ukuze uqiniseke ukuthi ubude bomshini wokunyathelisa buyiqiniso futhi buyisikwele.Qinisekisa ukuthi okokugcoba kwakho komdwebo kuhlungwe kahle futhi kugcinwe kahle, nokuthi inani lethuluzi lokusebenzisa kanye nendawo ye-nozzle kulungisiwe.Futhi uhlole ngokucophelela amathuluzi ukuze uhlole futhi uhlole ngokucophelela indawo yokunyathelisa. qaphela ngokukhethekile ukudweba i-radii; i-geometry ne-surface finish kufanele iphelele.
Futhi, ngenkathi amakhasimende ejwayele ukubuka i-304L kanye ne-304 ejwayelekile njengezishintshashintshayo, i-304L iyindlela engcono yokukhetha ukudweba. ukusetha umumo owenziwe.Kulula ukuyisebenzisa.
