Ipayipi lokugoba lokungeniswa
Kuyini i-Induction Bending?
Ukugoqa kokungeniswa iyindlela elawulwa ngokunembile nesebenzayo yokugoba amapayipi. Ukushisisa kwendawo kusetshenziswa amandla kagesi enziwa imvamisa ephezulu kusetshenziswa phakathi nenqubo yokugoba kokungeniswa. Amapayipi, amashubhu, ngisho nezimo zesakhiwo (iziteshi, izigaba ze-W & H) zingagotshwa kahle emshinini wokugoba wokungeniswa. Ukugoba okungeniswayo kwaziwa nangokuthi ukugoba okushisayo, ukugoba okukhuphukayo, noma ukugoba kwemvamisa ephezulu. Kumadayimitha amapayipi amakhulu, lapho izindlela zokugoba ezibandayo zilinganiselwe, Ukugoba kokungeniswa inketho ekhethwa kakhulu. Eceleni kwepayipi elizogotshwa, kubekwa ikhoyili yokungeniswa eshisisa isiyingi sepayipi ebangeni lika-850 - 1100 degrees Celsius.
Umshini wokugoba wokungenisa/umshini weshubhu udwetshiwe esithombeni. Ngemva kokumisa ipayipi nokubopha ngokuvikelekile iziphetho zalo, amandla asetshenziswa ku-inductor yohlobo lwe-solenoid ehlinzeka ngokushisa okujikelezayo kwepayipi endaweni lapho izogotshwa khona. Lapho ukusabalalisa kwezinga lokushisa okunikeza i-ductility eyanele ensimbi endaweni yokugoba sekufinyelelwe, ipayipi libe seliphushwa kukhoyili ngesivinini esithile. Indawo ehamba phambili yepayipi, eboshelwe engalweni egobayo, ingaphansi kwesikhashana sokugoba. Ingalo egobayo ingazungeza ifike ku-180°.
Ekugobeni kokungeniswa kwepayipi lensimbi ye-carbon, ubude bebhande elishisayo ngokuvamile buba ngu-25 kuya ku-50 mm (1 kuya ku-2 in.), nezinga lokushisa elidingekayo lokugoba ku-800 kuya ku-1080 ° C (1470 kuya ku-1975 ° F) ububanzi. Njengoba ipayipi lidlula ku-inductor, ligoba ngaphakathi kwendawo eshisayo, edonsa ngamapayipi ngenani elishiwo yirediyasi ye-pivot yengalo egoqayo, kuyilapho umkhawulo ngamunye wesifunda esishisayo usekelwa ingxenye yepayipi ebandayo, engaguquki. Kuye ngesicelo,
isivinini sokugoba singasukela ku-13 siye ku-150 mm/min (0.5 kuya ku-6 in./min). Kwezinye izinhlelo zokusebenza lapho kudingeka khona ama-radio amakhudlwana, isethi yamaroli isetshenziselwa ukunikeza amandla adingekayo okugoba esikhundleni se-pivot yengalo egobayo.Ngemva kokugoba, ipayipi liyapholiswa libe kuzinga lokushisa elizungezile kusetshenziswa isifutho samanzi, umoya ophoqelelwe, noma wemvelo. ukupholisa emoyeni. Ukunciphisa ukucindezeleka noma ukuthukuthela kungenziwa ukuze kutholwe izakhiwo ezidingekayo zokugoba.
Ukunciphisa udonga: Ukushisisa okungeniswayo kunikeza ukufudumeza okuyisiyingi okusheshayo kwezindawo ezikhethiwe zepayipi, kudla inani elincane lamandla uma kuqhathaniswa nezinye izinqubo zokugoba ezishisayo lapho ipayipi lonke lishiselwa khona. Kukhona nezinye izinzuzo ezibalulekile ezinikezwa ukugoba kweshubhu lokungeniswa. Lokhu kufaka phakathi ukuhlanekezelwa komumo okubikezelwa kakhulu (i-ovality) nokuncishiswa kodonga. Ukunciphisa nokubikezelwa kokucwecwa kodonga kubaluleke kakhulu lapho kukhiqizwa amashubhu namapayipi okufaka izicelo okufanele ahlangabezane nezimfuneko zokucindezela okukhulu, njengamandla enuzi namapayipi kawoyela/igesi. Isibonelo, izilinganiso zamapayipi kawoyela negesi zisekelwe ekugqileni kodonga. Ngesikhathi sokugoba, uhlangothi olungaphandle lokugoba lunengcindezi futhi lunesigaba esiphambanayo esincishisiwe, kuyilapho uhlangothi lwangaphakathi lukucindezelwa. Lapho ukushisisa okuvamile kusetshenziswa ekugobeni, ingxenye ephambanayo yohlangothi olungaphandle lwendawo egobile ngokuvamile iyancipha ngo-20% noma ngaphezulu okuholela ekuncishisweni okuhambisanayo kwenani eliphelele lokulinganisa umfutho wepayipi.
With Ukushisa ukufakelwa, ukuncishiswa kwesigaba esiphambanayo kwehliselwe ku-11% ngokujwayelekile ngenxa yokushisisa okulinganayo, uhlelo lokugoba olulungiselelwe ngomshini wokugoba owenziwe ngekhompyutha, kanye nendawo encane eyenziwe ngepulasitiki (i-ductile). Ngenxa yalokho, ukushisa kokungeniswa akunciphisi kuphela izindleko zokukhiqiza futhi kwenyuse ikhwalithi yokugoba, kodwa futhi kunciphisa izindleko eziphelele zamapayipi.
Ezinye izinzuzo ezibalulekile zokugoba kokungeniswa: akugxili kakhulu ekusebenzeni kanzima, kunomphumela omncane ekuqedeni kwendawo, futhi inamandla okwenza i-radii encane, eyenza ukugoba kwamashubhu amancane kanye nokukhiqizwa kwamajika amaningi / ukugoba okuningi kwipayipi elilodwa.
Izinzuzo zokugoba kokungeniswa:
- Irediya enkulu yokuhamba kahle koketshezi.
- Ukusebenza kahle kwezindleko, izinto eziqondile zibiza kancane kunezingxenye ezijwayelekile (isb. izindololwane) futhi ukugoba kungakhiqizwa ngokushesha kunokuba izingxenye ezijwayelekile zingashiselwa.
- Izindololwane zingathathelwa indawo ama-radius amajika amakhudlwana lapho kufanele khona futhi kamuva ukungqubuzana, ukuguga namandla okumpompa kungancishiswa.
- Ukugoba kokungeniswa kunciphisa inani lokushisela ohlelweni. Isusa ama-welds ezindaweni ezibucayi (ama-tangents) futhi ithuthukise ikhono lokudonsa ingcindezi nokucindezeleka.
- Ukugoba kokungeniswa kunamandla kunezindololwane ezinokuqina kodonga olufanayo.
- Ukuhlolwa okuncane okungangonakali kwama-welds, njengokuhlolwa kwe-X-ray kuzokonga izindleko.
- Izindololwane kanye nokugoba okujwayelekile kungancishiswa kakhulu.
- Ukufinyelela okusheshayo ezintweni eziyisisekelo. Amapayipi aqondile atholakala kalula kunezindololwane noma izingxenye ezijwayelekile futhi ukugoba cishe kungakhiqizwa ishibhile futhi ngokushesha.
- Kudingeka inani elilinganiselwe lamathuluzi (akukho ukusetshenziswa kwameva noma ama-mandrels njengoba kudingekile ekugobeni okubandayo).
- Ukugoba kokungeniswa kuyinqubo ehlanzekile. Akukho lubrication edingekayo kule nqubo futhi amanzi adingekayo ukuze ukupholisa agaywe kabusha.
UBUHLE BOKUSEBENZISA UKUGOBISWA KWE-INDUCTION

- Ipayipi nezinye izingxenye zingagoba zibe yirediya emincane kunanezindlela zokugoba ezibandayo.
- Indawo ebonakalayo ayithintekile/ayinasici ngenqubo.
- Ukugoba okuningi okunokwenzeka kubude obubodwa bepayipi.
- Ukuncipha kwesidingo sokushisela ngokugoba okuhlanganisiwe, ukuthuthukisa ubuqotho bokusebenza kwamapayipi.
- Ama-Welds agwenywe ezindaweni ezibucayi.
- Isidingo esincane sokuhlola okungabhubhisi, izindleko zokushayela ziyehla kakhulu.
- Iyashesha futhi iyonga amandla kakhudlwana kunezindlela zokugoba ze-slab ezishisayo.
- Inqubo iqeda isidingo sokugcwaliswa kwesihlabathi, ama-mandrels noma ama-formers.
- Inqubo ehlanzekile, engenawo amafutha okugcoba.
- Izinguquko zokucaciswa kwe-goba zingenzeka kuze kube umzuzu wokugcina ngaphambi kokukhiqiza.
- Isidingo esincishisiwe sokuhlolwa okusemthethweni endaweni yobuqotho obuhlangene obushiselwe.
- Izikhathi zokuhola zokulungisa nokulungisa ngokushesha, ngenxa yokulula okuhlobene kokukhiqiza amapayipi noma amashubhu afakwa esikhundleni agobile.
