Izinqubo eziyisisekelo zokufoja mahhala zifaka ukucasula, ukwelula, ukubhoboza, ukugoba, ukusonta, ukususa indawo, ukusika, nokufoja.
I-elongation yamahhala
Ukwelulwa, okwaziwa nangokuthi isandiso, kuyinqubo yokubumba eyehlisa indawo ephambanayo ye-billet futhi ikhulise ubude bayo. I-elongation ivame ukusetshenziselwa ukubumba induku kanye nezingxenye ze-shaft. Kunezindlela ezimbili eziyinhloko zokwelula: 1. ukwelula ku-anvil eyisicaba. 2. Nweba phezu kwenduku ewumgogodla. Ngesikhathi sokuqanjwa, induku ewumongo ifakwa endaweni engenalutho ebhontshiwe bese yelulwa njengento engenalutho eqinile. Uma udweba, ngokuvamile akwenziwa ngesikhathi esisodwa. Okungenalutho kuqala kudonswa ekubunjweni kwe-hexagonal, kuhlanganiswe ubude obudingekayo, bese ku-chamfer futhi kuyindilinga, bese kuphuma induku ewumgogodla. Ukuze kube lula ukukhishwa kwe-core rod, ingxenye esebenzayo ye-core rod kufanele ibe nomthambeka ozungeze u-1:100. Le ndlela yokwelula ingakhuphula ubude be-billet engenalutho, inciphise ukujiya kodonga, futhi igcine ububanzi obungaphakathi. Ivamise ukusetshenziselwa ukubumba uhlobo lwezimbotshana ezinde ezingenalutho.
Ukukhohlisa nokucasula kwamahhala
Ukucasula kuyinqubo yokubumba eyehlisa ukuphakama kokungenalutho futhi ikhulise indawo ephambanayo. Inqubo yokucasula isetshenziswa kakhulu ukwenza izikhala zegiya kanye namakhekhe ayindilinga. Inqubo ecasulayo ingathuthukisa ngempumelelo i-microstructure ye-billet futhi inciphise i-anisotropy yezakhiwo zemishini. Inqubo ephindaphindiwe yokucasula nokwelula ingathuthukisa i-morphology kanye nokusatshalaliswa kwama-carbides ensimbi yensimbi ye-alloy ephezulu. Kunezinhlobo ezintathu eziyinhloko zokucasula: 1. Ukucasula okuphelele. Ukucasula okuphelele kuyinqubo yokubeka okungenalutho ku-anvil surface, futhi ngaphansi komthelela we-anvil engenhla, okungenalutho kungena ukuguqulwa kwepulasitiki ngokuncipha kobude kanye nokwanda kwendawo ye-cross-sectional. 2. Phelisa ukucasuka. Ngemva kokushisa okungenalutho, ingxenye eyodwa ifakwa epuletini elivuzayo noma isikhunta sesondo ukuze kukhawulwe ukuwohloka kwepulasitiki kwale ngxenye, bese kuthi enye ingxenye engenalutho igaywe ngesando ukuze kwakheke ukucasula. Indlela ecasulayo yokusebenzisa amapuleti alahlekile ivame ukusetshenziselwa ukukhiqizwa kwenqwaba encane; Indlela yokucasula isikhunta sesondo ivame ukusetshenziselwa ukukhiqiza ngobuningi. Ngaphansi kwezimo zokukhiqiza ucezu olulodwa, izingxenye ezidinga ukucasuka zingashiswa endaweni, noma izingxenye ezingadingi ukucasuka zingacinywa emanzini ngemva kokushisa okugcwele, bese ukucasuka kungenziwa. 3. Ukucasuka kwaphakathi. Le ndlela isetshenziselwa ukufoja ama-forging anengxenye enkulu emaphakathi nengxenye yokugcina encane, njengezikhala zegiya elinabaphathi nhlangothi zombili. Ngaphambi kokucasula okungenalutho, iziphetho zombili zokungenalutho zidinga ukuhoxiswa kuqala, bese okungenalutho kugaywe kume mpo phakathi kwamapuleti amabili avuzayo ukuze kuphazamiseke ingxenye emaphakathi yokungenalutho. Ukuze uvimbele ukugoba kwe-billet ngesikhathi sokuphazamiseka, isilinganiso sobude be-billet h kuya ku-diameter dh/d singu-≤ 2.5.
Ukushaya ngesibhakela samahhala
Ukubhoboza kuyinqubo yokubumba ehlanganisa ukubhoboza noma ngezimbobo endaweni engenalutho. Kunezindlela ezimbili eziyinhloko zokubhoboza: 1. Indlela yokubhoboza ezinhlangothini ezimbili. Uma usebenzisa i-punch ukuze ushaye okungenalutho ekujuleni kwe-2 / 3-3 / 4, susa i-punch, flip okungenalutho, bese uqondanisa i-punch nesimo esivela ngakolunye uhlangothi ukuze ukhiphe umgodi. 2. Indlela yokushaya ngesibhakela ehlangothini olulodwa. Indlela yokubhoboza ohlangothini olulodwa ingasetshenziselwa amabhilidi anogqinsi oluncane. Lapho ubhoboza, okungenalutho kufakwa endandeni yokusekela, futhi ukuphela okukhulu kwe-punch tapered kancane kuhambisana nesimo sokubhoboza. Okungenalutho kukhandwa kuze kungene imbobo.
