Xa kusenziwa kwidayi eqhubekayo, uxinzelelo lwesibambi esingenanto, iimeko zoxinzelelo, kunye nezinto eziluhlaza zonke zichaphazela amandla okufumana iziphumo zokunwebeka ezingaguqukiyo ngaphandle kokushwabana.
U: Sitsala iikomityi ngentsimbi engagqwaliyo yebanga lama-304. Kwindawo yokuqala yokumisa idayisi yethu eqhubekayo, sitsala ukuya kutsho kwiisentimitha ezingama-0.75 ubunzulu. Xa ndijonga ubukhulu bomda weflegi yesithuba esingenanto, umahluko ukusuka kwelinye icala ukuya kwelinye unokuba phezulu njengeesentimitha ezingama-0.003. Ukubetha ngakunye kwahlukile kwaye akubonakali kwindawo enye. Ndixelelwe ukuba kunento yokwenza nokulungiswa kwezinto eziluhlaza, mhlawumbi umda ongaphandle wekhoyili ephambili. Singayifumana njani ikomityi emile ngendlela efanayo ngaphandle kokushwabana?
A: Ndiyabona ukuba umbuzo wakho uphakamisa imibuzo emibini: okokuqala, utshintsho olufumanayo kwinkqubo yelotho, okwesibini, izinto ezisetyenzisiweyo kunye neenkcukacha zazo.
Umbuzo wokuqala ujongene neziphene ezisisiseko zoyilo lwezixhobo, ngoko ke makhe sijonge iziseko. Ukushwabana okungapheliyo kunye notshintsho lobukhulu emva kokutsalwa kwiiflange zekomityi kubonisa ukungonelanga kwezixhobo kwisitishi sakho sokuzoba idayisi esiqhubekekayo. Ngaphandle kokubona uyilo lwakho lwedayi, kuya kufuneka ndicinge ukuba i-draw punch kunye ne-die radii yakho kunye nezikhewu zazo ziyahlangabezana nazo zonke iiparameter zoyilo oluqhelekileyo.
Kwimizobo enzulu, isithuba esingenanto sibanjwa phakathi kwedayi yokudweba kunye nesibambi esingenanto, ngelixa isitshixo sokudweba sitsala izinto kwidayi yokudweba, sizitsale zijikeleze iradiyo yokutsala ukuze zenze iqokobhe. Kukho ukungqubana okukhulu phakathi kwedayi kunye nesibambi esingenanto. Ngexesha lale nkqubo, izinto zicinezelwa ecaleni, nto leyo ebangela ukushwabana kunye nokwandiswa kwe-radial yesibambi esingenanto ngokuchasene nokuhamba kwezinto. Ukuba uxinzelelo lokubamba luphezulu kakhulu, izinto ziya kuqhekeka phantsi kokutsalwa yidayi yokwelula. Ukuba iphantsi kakhulu, kuya kubakho ukushwabana.
Kukho umda phakathi kobubanzi beqokobhe kunye nobubanzi obungenanto obungenakudlulwa ukuze kusetyenziswe umzobo ngempumelelo. Lo mda uyahluka ngokwepesenti yokwandiswa kwezinto. Umgaqo jikelele yi-55% ukuya kwi-60% kumzobo wokuqala kunye ne-20% kumzobo ngamnye olandelayo. Umfanekiso 1 yifomyula eqhelekileyo yokubala uxinzelelo lwesibambi esingenanto olufunekayo ekusoluleni (ndihlala ndongeza ubuncinane amandla ongezelelweyo angama-30% njengento yokhuseleko, inokunciphisa ukuba kuyimfuneko, kodwa kunzima ukunyusa emva kokuba uyilo lugqityiwe).
Uxinzelelo lwe-blank holder p yi-2.5 N/mm2 yentsimbi, 2.0 ukuya kwi-2.4 N/mm2 yee-alloys zobhedu kunye ne-1.2 ukuya kwi-1.5 N/mm2 yee-alloys ze-aluminium.
Utshintsho kubukhulu beflange lubonisa nokuba uyilo lwesixhobo sakho alunamandla ngokwaneleyo. Izihlangu zakho zokubumba kufuneka zibe nkulu ngokwaneleyo ukumelana nokutsalwa ngaphandle kokujijeka. Inkxaso engaphantsi kwesihlangu sokubumba kufuneka ibe yintsimbi eqinileyo, kwaye izikhonkwane zesikhokelo sokubumba mazibe nkulu ngokwaneleyo ukuthintela nayiphi na intshukumo ecaleni kwe-die ephezulu nesezantsi ngexesha lokusolula.
Jonga iindaba zakho. Ukuba izikhokelo zokushicilela zigugile kwaye zingcolile, akunamsebenzi ukuba isixhobo sakho siqinile - awuyi kuphumelela. Jonga islayidi yokushicilela ukuqinisekisa ukuba ubude obupheleleyo bokucinezela buyinyani kwaye buyi-square. Qinisekisa ukuba i-lubricant yakho yokudweba ihluziwe kwaye igcinwe kakuhle, kwaye ubungakanani bokusetyenziswa kwesixhobo kunye nendawo ye-nozzle zizinzile. Hlola ngokucokisekileyo zonke izixhobo zokushicilela ukuqinisekisa ukugqitywa komphezulu ngokuchanekileyo, ukugquma, kunye nokulingana. Kwaye nikela ingqalelo ekhethekileyo kwi-radii yokudweba; i-geometry kunye nokugqitywa komphezulu wazo kufuneka zigqibelele.
Kwakhona, nangona abathengi bethanda ukubona i-304L kunye ne-304 eqhelekileyo njengetshintshiselanayo, i-304L lolona khetho lungcono lokuzoba. I-L imele ikhabhoni ephantsi, enika i-304L amandla okuvelisa angama-0.2% e-35 KSI kunye nama-304 e-0.2% e-42 KSI. Ngokunciphisa amandla okuvelisa angama-16%, i-304L ifuna amandla amancinci okuvelisa xa isenza kwaye imisela imo eyenziweyo. Kulula ukuyisebenzisa.
