Xa kusenziwa ukufa okuqhubekayo, uxinzelelo lomnini olungenanto, iimeko zoxinzelelo, kunye nezixhobo ezikrwada zonke zichaphazela ukukwazi ukufumana iziphumo ezilula ngaphandle kokushwabana.
Q: Sitsala iikomityi ukusuka kwibakala 304 steel stainless. Kwi-stop yokuqala yokufa yethu progressive, sitsalela malunga 0.75 intshi ubunzulu.Xa ndikhangela ubukhulu beperimitha flange engenanto, umahluko ukusuka kwelinye icala ukuya kwelinye unokuba phezulu 0.003 intshi.Into yonke hit yahlukile kwaye ayibonakali kwi-procession of the samest has been told to the same material of the radge out of the same. Ikhoyili engundoqo.Singayifumana njani ikomityi emile kakuhle ngaphandle kokushwabana?
A: Ndibona umbuzo wakho uphakamisa imibuzo emibini: okokuqala, utshintsho olufumanayo kwinkqubo yelotho, kwaye okwesibini, izinto eziluhlaza kunye neenkcukacha zabo.
Umbuzo wokuqala ujongene neziphene zoyilo lwesixhobo esisisiseko, ngoko ke makhe sihlolisise ukushwabana okusisiseko.Okunyakazayo kunye nokutshintsha kobunzima bekomityi kwiiflange zendebe zibonisa izikhewu ezingonelanga zesixhobo kwisikhululo sakho somzobo esiqhubekayo sokufa.Ngaphandle kokubona uyilo lwakho lokufa, bendiya kufuneka ndicinge ukuba umzobo wakho we-punch kunye neredidi yokufa kunye nezikhewu zazo zidibana nazo zonke iiparamitha zoyilo eziqhelekileyo.
Kumzobo onzulu, i-blank sandwiched phakathi komzobo wokufa kunye nomnini ongenanto, ngelixa i-punch yokudweba idonsa izinto kwi-drain die, ukuyisondeza kwi-radius yokudweba ukuze yenze i-shell.Kukho ukungqubuzana okukhulu phakathi kwe-die kunye nomnini ongenanto.Ngeli xesha, le nkqubo ixinzelelwe ngasecaleni, isizathu sokuba ukushwabana kunye ne-radial elongation phantsi kwe-radial elongation phantsi kwe-blank elongation. ye punch yolula.Ukuba iphantsi kakhulu, ukushwabana kuya kwenzeka.
Kukho umda phakathi kwedayamitha yeqokobhe kunye nedayamitha engenanto engenakugqithiswa kumsebenzi ophumeleleyo womzobo.Lo mda uyahluka ngepesenti yokwandiswa kwezinto.Umgaqo jikelele ngu-55% ukuya kwi-60% kumzobo wokuqala kunye ne-20% kumzobo ngamnye olandelayo.Umfanekiso we-1 yifomula esemgangathweni yokubala ingcinezelo yomphathi ongenanto efunekayo ukuze kunwenwe (i-30 isoloko iyancipha, kodwa i-30 yongeza i-force eyongeziweyo, i-30 iphinda idityaniswe, kodwa i-30 iphinda ihlanjululwe ngokukhawuleza, kodwa i-30 iphinda ihlanjululwe, kodwa i-30 iyancipha. uyilo lugqityiwe).
I-blank holder pressure p yi-2.5 N / mm2 yensimbi, i-2.0 ukuya kwi-2.4 N / mm2 ye-alloys zethusi kunye ne-1.2 ukuya kwi-1.5 N / mm2 ye-aluminium alloys.
Ukwahluka kwi-flange ubukhulu ikwabonisa ukuba uyilo lwakho lwesixhobo alunamandla ngokwaneleyo.
Khangela kwakhona iindaba zakho.Ukuba izikhokelo zeendaba zigugile kwaye zi-sloppy, akunamsebenzi ukuba isixhobo sakho sinamandla-awuyi kuphumelela.Jonga isilayidi sokushicilela ukuqinisekisa ukuba ubude obugcweleyo bokushicilela buyinyaniso kwaye buyisikwere.Qinisekisa ukuba i-lubricant yakho yomzobo ihluzwe kakuhle kwaye igcinwe, kwaye ukuba isicelo sesixhobo kunye nesikhundla sombhobho zilungisiwe.Kwaye qwalaselo olukhethekileyo lwezixhobo, printa ngokucophelela kwaye uhlolisise kakuhle. umzobo weradiyi;ijometri kunye nokugqitywa komphezulu kufuneka kugqibelele.
Kwakhona, ngelixa abathengi bevame ukujonga i-304L kunye ne-304 esemgangathweni njengento etshintshayo, i-304L iyona nto ingcono yokukhetha ukudweba. Kulula ukuyisebenzisa.
