Xa ubetha ngenqindi kwaye ugoba ngaphakathiisitampu sentsimbi, indawo yokuguqulwa inqunyelwe ngokusisiseko ngaphakathi kwefayili yokufa.Ngaphantsi kwesenzo soxinzelelo lwe-unidirectional okanye lwe-bidirectional tensile, i-tangential elongation deformation inkulu kune-deformation ye-radial compression, ekhokelela ekunciphiseni ubukhulu bezinto.Umlomo womphetho othe nkqo womngxunya we-flanging uyancitshiswa ukuya kubuninzi.Xa ubukhulu buncitshiswe kakhulu kwaye ulwandiso lwempahla lugqithisa umda wokwandiswa kwezinto, oko kubizwa ngokuba yi-p fracture kwenzeka (ukuqhekeka okubangelwa kubude obugqithisileyo kunye nokungonelanga kweplastikhi yesixhobo kubizwa ngokuba yi-force anus fracture; ukwenza amandla kunye namandla anganeleyo ezinto ezibizwa ngokuba yi-fracture).Xa ubethelwa ngenqindi kunye nokujinga, okukhona incinci i-coefficient K ye-flanging, inqanaba elikhulu le-deformation, kunye nokuncitshiswa okukhulu komphetho womlomo othe nkqo, kokukhona kulula ukuqhekeka.Ke ngoko, ukucuthwa kobungqingqwa bomlomo othe nkqo akukwazi ukungahoywa xa ujika.
1.Iintanda zenzeke kwisangqa sokuvuleka komngxuma.Esona sizathu siphambili kukuba icandelo le-punched pre hole linendawo yokukrazula kunye ne-burr, apho kukho indawo yoxinzelelo.Ngethuba lenkqubo yokuguqula umngxuma, iplastiki yale ndawo impofu kwaye kulula ukuyiqhekeza.Ukusetyenziswa kwezinto ezinobude obuhle kunokunyusa iqondo lokuguqulwa kwe-punching hole flanging kunye nokunciphisa ukuqhekeka komngxuma.Ukuba ukubunjwa kuvunyelwe, i-diameter ye-pre hole iya kwandiswa kangangoko kunokwenzeka ukunciphisa ukuguqulwa komngxuma, oluncedo ekunciphiseni ukuqhekeka komngxuma.Ukuba ulwakhiwo luvumela, izinto ezicekethekileyo ziya kusetyenziswa kangangoko ukunyusa umlinganiselo ozalanayo (D 0/t) we-pre hole, eluncedo ekunciphiseni amathuba okuqhekeka komngxuma.Xa uyila i-mold, kungcono ukwamkela i-parabolic okanye i-spherical shape ye-flanging punch, enokunyusa ukuguqulwa okuvumelekileyo kwezinto zendawo kunye nokunciphisa ukuqhekeka.Ngexesha le-stamping, isalathiso sokubetha kunye ne-flanging sinokuchasana nokubetha kunye nokugaya kwangaphambili, ukwenzela ukuba i-burr ibekwe ngaphakathi kwe-flanging, enokunciphisa ukuqhekeka.
2. Emva kokuba i-stamping kunye ne-flanging hole ivaliwe, umgodi uyancipha, i-flange ayikho ngokuthe nkqo, kwaye ububanzi bomgodi buba buncinci, okuya kwenza kube nzima ukukrazula ngexesha lokuhlanganisa.Izizathu eziphambili zentamo ziyi-springback yezinto, kwaye i-gap z / 2 phakathi kwe-punch kunye nokufa inkulu kakhulu.Izinto eziphathekayo ezinomsebenzi omhle zisetyenziselwa imveliso, kunye ne-rebound encinci, enokuphucula ingxaki yentamo.Xa uyila idayizi, ukukhetha indawo efanelekileyo yokuvula phakathi kwenkunzi nemazi kunokuqinisekisa ukuba i-flanging flange ime nkqo.Ukucocwa phakathi kwe-punch kunye ne-die ngokuqhelekileyo kungaphantsi kancinane kunobunzima bezinto eziphathekayo.
3. Ukuphakama okunganeleyo kwe-flanging flange kunciphisa ngokuthe ngqo ubude be-screwing of screw kunye nomngxuma kwaye kuchaphazela ukuthembeka kwe-screw connection.Imiba echaphazela ukuphakama kweflange ye-stamping flanging ibandakanya ukugqithisela kwedayamitha ye-pre hole, njl.njl. Khetha umngxuma omncinci wedayamitha yokugqobhoza kwangaphambili ukwandisa ubude bomngxuma ojikayo.Xa i-diameter ye-pre hole ayinakuncitshiswa, i-thinning kunye ne-flanging ingamkelwa ukwenza udonga lube lukhuni ukunyusa ukuphakama kwe-flanging flange.
4. Ingcambu ye-R yokubetha kunye ne-flanging inkulu kakhulu.Emva kwe-flanging, ingcambu ye-R inkulu kakhulu, eya kubangela ukuba inxalenye enkulu yengcambu ayinakho ukudibanisa ne-screw ngexesha lokudibanisa, ukunciphisa i-screw ubude be-screw kunye nomngxuma, kunye nokunciphisa ukuthembeka kwe-screw connection.Ingcambu engu-R yomngxuma we-flanging inkulu kakhulu, ehambelana nobukhulu bezinto kunye nefayili yokungena ye-stamping flanging die.Ubuninzi bezinto eziphathekayo, inkulu ingcambu engu-R iya kuba;Inkulu i-fillet ekungeneni kwe-die, inkulu i-R kwingcambu ye-flanging hole.Ukunciphisa ingcambu ye-R ye-flanging hole, izinto ezincinci kufuneka zikhethwe ngokusemandleni.Xa uyila ukufa, iifillet ezincinci ekungeneni kokufa kwemazi kufuneka ziyilwe.Xa kusetyenziswa izinto ezityebileyo okanye iifillet ekungeneni kwefamakazi zingaphantsi kwamaxesha ama-2 ubukhulu bezinto eziphathekayo, i-flanging punch iya kuyilwa ukunyusa igxalaba ngokubunjwa, kwaye ingcambu ye-R iya kubunjwa ekupheleni kwesitampu. stroke, okanye inkqubo yokubumba iya kongezwa ngokwahlukileyo.
5. Xa imingxuma yokubhobhoza kunye ne-flanging icutshungulwa ngokubethelwa kunye ne-flanging inkunkuma yezinto, akukho sakhiwo esihambelanayo esihambelana ne-concave die ngexesha lokubetha, kwaye izinto eziphathekayo zitsalwa.Izinto ezilahlwayo zokugqobhoza zinokubambelela ngokungenamkhethe kumngxunya, okukhokelela ekubetheni rhoqo kwenkunkuma.Ukushukuma kwezinto ezilahlwayo ngexesha lokuchola kunye nokuphatha kulula ukusabalalisa kwindawo yokusebenza yokufa okanye inxalenye, ebangela iziphene ze-indentation phezu kwendawo, efuna ukulungiswa ngesandla, Kunzima ukuhlangabezana neemfuno zangaphandle. iindawo eziza kulungiswa, kwaye zinokuchithwa kuphela, zichithe abasebenzi kunye nezixhobo;Izinto ezichithwayo zemingxuma ye-flanging, ukuba iziswe kwindibano jikelele, kulula ukunqumla abaqhubi kunye nokuchaphazela i-screwing;Kwiindawo zombane, ezifana ne-flanging hole waste, kulula ukubangela isiphaluka esifutshane xa iwela kumacandelo ombane ngexesha le-screwing, okuya kubangela iingxaki zokhuseleko lombane.
