Indololwane engenamthungo: Indololwane wuhlobo lokufakwa kwepayipi elisetshenziswa ekujikeni kwepayipi. Kuhlelo lwamapayipi okusetshenziswa kuwo wonke amapayipi okufakwayo, ingxenye enkulu kunazo zonke, cishe ama-80%. Ngokuvamile, izinqubo ezahlukene zokwakha zikhethwa ngezindololwane zezinto ezihlukahlukene noma ubukhulu bodonga. Izitshalo ezikhiqizayo ezivame ukusetshenziselwa inqubo yokwakheka kwendololwane engenamthungo ukusunduza okushisayo, ukugxiviza, i-extrusion, njll.
I-Hot push forming
Inqubo yokwakhiwa kwendololwane eshisayo isebenzisa umshini okhethekile wokusunduza indololwane, isikhunta esiyinhloko kanye nedivayisi yokushisa, ukuze isethi ye-billet esikhunjini emshinini wokusunduza iqhubekisele phambili ukunyakaza, ekunyakazeni kuyashiswa, kunwetshwe futhi kugobelwe ngaphakathi. inqubo. Izici ze-deformation ye-hot push elbow zisekelwe emthethweni wokuguqulwa kwepulasitiki yezinto zensimbi ngaphambi nangemva komthamo we-billet ububanzi, ububanzi be-billet esetshenzisiwe bungaphansi kobubanzi bendololwane, ngokusebenzisa isikhunta esiyinhloko ukulawula. inqubo ye-deformation ye-billet, ukuze i-arc yangaphakathi yokugeleza kwensimbi ecindezelwe ukunxephezela ukunwetshwa nokuncipha kwezinye izingxenye, ukuze kutholwe ukushuba kodonga olufanayo lwendololwane.
Inqubo yokwakhiwa kwendololwane eshisayo inokubukeka okuhle, ukushuba kodonga olufanayo nokusebenza okuqhubekayo, kulungele ukukhiqizwa ngobuningi, ngaleyo ndlela ibe indlela eyinhloko yokwenza i-carbon steel, i-alloy steel elbow, futhi isetshenziswa ekwakhiweni kokucaciswa okuthile kwendololwane yensimbi engagqwali.
Izindlela zokushisisa inqubo yokwakha imvamisa emaphakathi noma i-high frequency induction heat (indilinga yokushisa ingaba yi-multi-turn noma ijika elilodwa), ukushisisa ilangabi kanye nokushisa kwesithando somlilo, ukusetshenziswa kwendlela yokushisa ngokuya ngezidingo zomkhiqizo wokwakha kanye nesimo samandla. .
Ukugxiviza
Indololwane yokwakha isitembu yiyona yokuqala eyasetshenziswa ekukhiqizweni kwenqwaba yenqubo yokwakheka kwendololwane engenamthungo, ekukhiqizeni izincazelo ezivame ukusetshenziswa indololwane ithathelwe indawo yi-hot push method noma enye inqubo yokwakha, kodwa kwezinye izicaciso zendololwane ngenxa yokukhiqizwa kwendololwane encane. ubuningi, ukujiya kodonga obukhulu kakhulu noma mncane kakhulu.
Umkhiqizo usasetshenziswa uma kunezidingo ezikhethekile. I-elbow stamping kanye nokwakheka usebenzisa indololwane ngaphandle ububanzi elilingana billet, ukusetshenziswa yokunyathelisa isikhunta ngqo sicindezelwe ibe shape.
Ngaphambi kokunyathela isitembu, i-billet ifakwa ku-fa engezansi, i-core core kanye ne-end die ilayishwa ku-billet, futhi i-die engenhla ihlehla ukuze iqale ukucindezela, futhi indololwane yakhiwa ukuvinjelwa kwe-die yangaphandle kanye nokusekelwa ukufa kwangaphakathi.
Uma kuqhathaniswa nenqubo ye-push eshisayo, ukubukeka kwekhwalithi yokwenza isitembu akukuhle njengakuqala; ukunyathela indololwane ekwakhekeni kwe-arc yangaphandle esimweni esiqinile, azikho ezinye izingxenye zensimbi eyeqile ezizonxeshezelwa, ngakho ugqinsi lodonga lwe-arc yangaphandle lucishe lube ngu-10%. Kodwa ngenxa yezimpawu zokukhiqizwa kwesiqephu esisodwa kanye nezindleko eziphansi, ngakho-ke inqubo yendololwane yokunyathela isetshenziswa kakhulu ngamanani amancane, ukukhiqizwa kwendololwane enezindonga eziwugqinsi.
Indololwane enesitembu ihlukaniswe yaba izinhlobo ezimbili zokunyathela okubandayo kanye nokunyathela okushisayo, imvamisa ngokuya ngemvelo yempahla namandla wemishini yokukhetha isitembu esibandayo noma isitembu esishisayo.
Cold extrusion indololwane ukwakheka inqubo ukusetshenziswa umshini okhethekile indololwane ukwakha, i-billet ibe yangaphandle die, engenhla futhi aphansi kufa ngemva kokufa, ngaphansi push rod, billet eduze kufa kwangaphakathi nangaphandle kubekelwe ukunyakaza igebe futhi ephelele. inqubo yokwakha.
Ukusetshenziswa abandayo extrusion inqubo ngaphakathi nangaphandle die yokukhiqiza indololwane ukubukeka okuhle, umfaniswano odongeni ukushuba, usayizi omncane ukuchezuka, ukuze indololwane insimbi engagqwali, ikakhulukazi mncane-walled indololwane insimbi engagqwali ukwakha ngaphezu ukusetshenziswa le nqubo yokukhiqiza. Le nqubo idinga ukunemba okuphezulu kokufa kwangaphakathi nangaphandle; ukuchezuka kokuqina kodonga lwe-billet nakho kuyizidingo ezinzima.
Uhlelo lokushisela amapuleti
Sebenzisa ipuleti ngokucindezela ukwenza uhhafu wephrofayili yendololwane, bese uhlanganisa amaphrofayili amabili ndawonye. Inqubo enjalo ngokuvamile isetshenziselwa ukwenza i-DN700 noma ngaphezulu indololwane.
Ezinye izindlela zokwakha
Ngaphezu kwalezi zinqubo ezintathu ezingenhla ezivamile zokwakha, ukwakha indololwane engenamthungo kukhona ukusetshenziswa kwe-extrusion ye-billet ku-fa yangaphandle, bese ngenqubo yokubunjwa kwebhola le-billet. Kepha le nqubo iyinkimbinkimbi, inkinga yokusebenza, kanye nekhwalithi yokwakha ayilungile njengenqubo eshiwo ngenhla, ngakho-ke isetshenziswa kancane.
Kuwuhlobo lokufakwa kwamapayipi okuvame ukusetshenziswa ekufakweni kwepayipi ukuxhuma amapayipi amabili anobubanzi obufanayo noma obuhlukile obujwayelekile, ukuze ipayipi likwazi ukujika i-engeli ethile, futhi ukucindezela okulinganiselwe kube ngu-1-1.6Mpa.
Indololwane by angle, kukhona 45 °, 90 °, 180 ° ezintathu evame ukusetshenziswa, ngaphezu kwalokho, ngokuvumelana nezidingo zobunjiniyela, kuhlanganisa 60 ° nezinye angle non-evamile; ngokwenqubo yokukhiqiza, ingahlukaniswa ibe indololwane yokushisela, indololwane yokunyathela, indololwane ephusha, indololwane yokuphonsa, njll.
1.Njengoba izinto eziningi zokufakwa kwamapayipi zisetshenziselwa ukushisela, ukuze kuthuthukiswe izinga lokushisela, iziphetho ziguqulwa zibe ama-bevels, zishiye i-engeli ethile ngonqenqema oluthile, le mfuneko nayo iqinile, ukuthi umkhawulo ujiyile kangakanani, i-engeli. ukuthi kungakanani kanye nebanga lokuchezuka elicacisiwe. Izinga eliphezulu kanye nezakhiwo zemishini ngokuyisisekelo zifana nalezo zepayipi. Ukuze kube lula ukushisela, uhlobo lwensimbi lokufakwa kwamapayipi kanye nepayipi elixhunyiwe kuyafana.
2.ukuthi konke ukufakwa kwamapayipi kungaphansi kokwelashwa okungaphezulu, indawo engaphakathi nengaphandle ye-iron oxide ngokufafazwa ngokudubula kokuqhuma, bese kugcotshwa ngopende ovimbela ukugqwala. Lena izidingo ukuthekelisa, ngaphezu kwalokho, kuleli zwe futhi lula ezokuthutha ukuvimbela ukugqwala kanye oxidation, kukhona ukwenza lo msebenzi.
3.kuyisidingo sokupakishwa kokufakwa kwamapayipi amancane, njengokuthunyelwa kwamanye amazwe, udinga ukwenza amabhokisi okhuni, cishe ama-cubic metres ayi-1, inani lezindololwane emabhokisini anjalo alikwazi ukudlula ngethani, izinga livumela amasethi, okungukuthi, amasethi amakhulu. encane, kodwa isisindo esiphelele asikwazi ukudlula ithani elingu-1. Ukuze izingcezu ezinkulu zika-y zibe iphakheji elilodwa, njengo-24″ kumele kube iphakheji elilodwa. Olunye uphawu lokupakisha, uphawu ukukhombisa usayizi, inombolo yensimbi, inombolo ye-batch, uphawu lokuthengisa lomkhiqizi, njll.
