Xa kusenziwa ukufa okuqhubekayo, uxinzelelo lomnini olungenanto, iimeko zoxinzelelo, kunye nezixhobo ezikrwada zonke zichaphazela ukukwazi ukufumana iziphumo ezilula ngaphandle kokushwabana.
Umbuzo: Sidweba iikomityi ukusuka kwibakala le-304 yensimbi engenasici. Kwi-stop yokuqala yokufa kwethu okuqhubekayo, sidonsa malunga ne-0.75 intshi ubunzulu.Xa ndihlola ubukhulu be-perimeter ye-flange ye-blank, umehluko ukusuka kwelinye icala ukuya kwelinye unokuba phezulu njenge-0.003 intshi.I-hit nganye iyahluka kwaye ayibonakali kwi-processing edibeneyo, mhlawumbi, i-processing ixelelwe kwindawo enye. Umda ongaphandle wekhoyili engundoqo.Singayifumana njani ikomityi emile okwexesha lonke 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 malunga ne-radius yokudweba ukwenza i-shell.Kukho ukungqubuzana okukhulu phakathi kokufa kunye nomnikazi ongenanto.Ngethuba le nkqubo, izinto zixinzelelwe ngasecaleni, isizathu sokushwabana kunye ne-radial elongation ye-radial elongation ye-blank elongation. iya kuphuka phantsi kokutsalwa kwe-stretch punch.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 1 yifomula esemgangathweni yokubala umninimzi ongenanto uxinzelelo olufunekayo ukuze ndisolule (i-30 ndihlala ndongeza i-force eyongezelelweyo, i-30 ndihlala ndidibanisa ukhuseleko oluncinci. efunekayo, kodwa kunzima ukwandisa emva kokuba 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.
Iiyantlukwano kwi-flange ubukhulu ikwabonisa ukuba uyilo lwesixhobo sakho asinamandla ngokwaneleyo.
Jonga iindaba zakho nawe.Ukuba izikhokelo zoshicilelo zigugile kwaye zigugile, akukhathaliseki nokuba isixhobo sakho siqinile-awuyi kuphumelela.Jonga isilayidi sokushicilela ukuze uqiniseke ukuba ubude obupheleleyo bokushicilela bunyanisile kwaye busisikwere.Qinisekisa ukuba isithambiso sakho somzobo sihluzwe kakuhle kwaye sigcinwe, kwaye isixa sesicelo sesixhobo kunye nesikhundla sombhobho zilungisiwe.Jonga isilayidi sokushicilela ukuze uqinisekise ukuba ubude obupheleleyo bokushicilela buyinyaniso kwaye buyisikweri.Qinisekisa ukuba isithambiso sakho somzobo sihluzwe kakuhle kwaye sigcinwe, kwaye isixa sesicelo sesixhobo kunye nesikhundla sombhobho zilungisiwe.Jonga ngokucokisekileyo, printa ngokucokisekileyo kwaye uhlolisise zonke izixhobo. nikela ingqalelo ekhethekileyo ekudwebeni iradio; ijometri kunye nokugqitywa komphezulu kufuneka kugqibelele.
Kwakhona, ngelixa abathengi bevame ukujonga i-304L kunye ne-304 esemgangathweni njengento etshintshayo, i-304L iyona ndlela engcono yokukhetha ukudweba. ukuseta imilo eyenziweyo.Kulula ukuyisebenzisa.
