Yiziphi izinhlobo ezahlukene zokuxhuma kwensimbi?

Izixhumanisi ziyizakhi zesakhiwo ezisetshenziselwa ukujoyina amalungu ahlukene ohlaka lwensimbi yesakhiwo. Isakhiwo Sensimbi siyinhlanganisela yamalungu ahlukene njengokuthi “Imishayo, Amakholomu” axhunywe kwelinye, ngokuvamile eziphethweni zelungu ukuze abonise iyunithi eyodwa eyinhlanganisela.

Izixhumanisi ezakhiweni zensimbi

· Izixhumanisi ezithuthukisiwe

Uke wawabona amabhuloho, izitimela, amabhayela, izindiza, noma izakhiwo ezinkulu ezibambene nesakhiwo esinjengenkinobho? Nokho, leyo nkinobho ibizwa ngokuthi i-Rivet. Amajoyinti a-riveted awuhlobo lwe-fastener eyimishini esetshenziselwa ukuhlanganisa izingcezu ezimbili noma ngaphezulu zezinto ndawonye. Aqukethe uchungechunge lwama-rivets, afakwa ngezimbobo zento futhi akhubazeke noma "abekwe" endaweni ukuze kwakhe ukuhlangana okuvikelekile.

I-rivet iyinduku eyindilinga esetshenziselwa ukuxhuma izakhiwo zensimbi ezimbili njengoba amajoyinti akhiwe ngalezi zinsimbi ezithambile noma zethusi zinamandla kunamajoyinti ashiselwe futhi zinikeza ukuhlangana okusheshayo.

Umdwebo 1: Isakhiwo se-Rivet

Ngamagama alula, i-riveted joint iwuhlobo oluhlala njalo lwe-fastener esetshenziselwa ukuhlanganisa amapuleti ensimbi noma izingxenye zensimbi ezigoqiwe ndawonye. Lawa majoyinti asetshenziswa kakhulu ezakhiweni zensimbi noma ezakhiweni ezinjengamabhuloho, ama-roof trusses, nasemikhunjini yokucindezela efana namathangi okugcina nama-boilers.

·Izixhumanisi eziboshiwe

Ijoyinti eliboshiwe liphakathi kwamajoyinti anentambo ajwayeleke kakhulu. Ziyindlela eyinhloko yokudlulisa umthwalo ezingxenyeni zomshini. Izakhi eziyinhloko zejoyinti eliboshiwe yi-fastened enentambo kanye namantongomane avimbela ukuxegiswa kwebhawodi.

Amajoyinti aboshiwe asetshenziswa kabanzi ekwakheni nasekuklanyweni komshini njengendlela yokuhlanganisa izingxenye ndawonye. Lolu hlobo lwejoyinti luhlanganisa into yokubopha enentambo yesilisa, njengebhawodi, kanye nentambo yesikulufu yesifazane efanayo evikela ezinye izingxenye endaweni. Amalunga e-tension kanye namajoyinti okugunda yizinhlobo ezimbili eziyinhloko zemiklamo ehlanganisiwe eboshiwe. Nakuba ezinye izindlela zokuhlanganisa, ezihlanganisa i-welding, i-riveting, i-adhesives, i-press fit fit, izikhonkwane, nezihluthulelo, nazo zivamile, amalunga aboshwe avame ukusetshenziselwa ukuxhuma izinto zokwakha futhi enze izakhiwo zemishini. Empeleni, ilunga eliboshiwe liyinhlanganisela yesixhumi namantongomane, anebhawudi ende nenathi eliyisibonelo esijwayelekile.

Amalunga Aboshiwe achazwa njengamalunga ahlukanisekayo asetshenziselwa ukubamba izingxenye zomshini ndawonye ngendlela yokubopha ngentambo, okungukuthi ibhawudi namantongomane. Njengoba lawa malungu ewuhlobo olungezona unomphela, amalungu angahlakazwa ukuze agcinwe, ahlolwe, futhi ashintshwe ngaphandle kokubeka engcupheni umonakalo ezingxenyeni ezithile.

Amalunga Aboshiwe aphakeme kakhulu kunamajoyinti ahlala njalo njengama-welds nama-rivets, abangela ukulimala ezingxenyeni lapho izingxenye zihlakazwa. Izicelo zihlanganisa ukuhlanganisa izingxenye ezimbili ezidinga ukuhlakazwa ngezikhathi ezithile.

Amalunga aboshwe ngokuyinhloko akhiwe izingxenye ezimbili. Kuyinhlanganisela ye-fastener namantongomane. Iqukethe ibhawodi elide elinamantongomane. Ibhawodi lifakwa embobeni ebhojwe ngaphambili ezingxenyeni, bese inathi libe seliqiniswa entanjeni yokukhwelana yebhawodi. Ukuxhumana okuboshiwe yitemu elihlangene lebhawodi namantongomane.

Imicu idalwe ngokudala i-helical groove ngaphandle kwe-shaft eyindilinga noma umgodi. Kunezinhlobonhlobo zezindawo zokusebenza kanye nokusetshenziswa kwamalunga aboshiwe. Kukhona izilinganiso ezimisiwe ezijwayelekile zazo zonke lezi zinhlobo ezahlukene. Lokhu kuqinisekisa ukuthi amalunga aboshiwe ayashintshana ngemikhiqizo ehlukene.

IZINHLOBO ZOKUXHUMANA OKUSHISELWE

Izinhlobo eziyisisekelo zamajoyinti ahlanganisiwe zingahlukaniswa kuye ngokuthi izinhlobo ze-welds, isikhundla se-welds kanye nohlobo lokuhlangana.

1. Ngokusekelwe ohlotsheni lwe-weld

Ngokusekelwe ohlotsheni lwe-weld, ama-welds angahlukaniswa abe yi-fillet weld, i-groove weld (noma i-butt weld), i-plug weld, i-slot weld, i-spot weld njll. Izinhlobo ezihlukahlukene zokushisela ziboniswa kuMfanekiso 15.

1.1. I-Groove welds (ama-butt welds)

Ama-welds ama-groove (ama-butt welds) kanye nama-weld we-fillet anikezwa lapho amalungu azohlanganiswa ekleliswe. Ama-groove weld ayabiza kakhulu njengoba adinga ukulungiswa. Ama-groove welds angasetshenziswa ngokuphepha kumalungu acindezeleke kakhulu. Amashisela ezinqenqemeni eziyisikwele ahlinzekwa ngokujiya kwepuleti elingu-8mm kuphela. Izinhlobo ezahlukene zokushisela izinqe zikhonjiswa kuMfanekiso 16.

1.2. Ama-welds we-fillet

Ama-weld we-fillet anikezwa lapho amalungu amabili azohlanganiswa esendizeni ehlukene. Njengoba lesi simo senzeka kaningi, ukushisela kwe-fillet kuvame kakhulu kunama-butt welds. Ama-weld we-fillet kulula ukwenza njengoba kudinga ukulungiswa okuncane kwendawo. Noma kunjalo, azinamandla njenge-groove welds futhi abangela ukugxila kwengcindezi. Ama-weld we-fillet akhethwa emalungwini agcizelelwe kancane lapho ukuqina kunokuba namandla kubuse umklamo. Izinhlobo ezahlukahlukene zama-fillet welds zikhonjiswe kuMfanekiso 17.

1.3. Slot futhi ipulaki welds

Ama-slot kanye nama-plug welds asetshenziselwa ukwengeza ukushisela kwe-fillet lapho ubude obudingekayo be-fillet weld bungenakufinyelelwa.

2. Ngokusekelwe esikhundleni se-weld

Ngokusekelwe esikhundleni se-weld, ama-welds angahlukaniswa abe yi-weld flat, weld enezingqimba, i-vertical weld, i-overhead kahle njll.

Ngokusekelwe ohlotsheni lwamalunga

Ngokusekelwe ohlotsheni lwamalunga, ama-welds angahlukaniswa abe amajoyinti ashiselwe izinqe, amajoyinti ashiselwe emathangeni, amalunga ashiselwe ama-tee kanye namajoyinti ashiselwe ekhoneni.
