Vula iindawo zokubumba

Iinkqubo ezisisiseko zokubumba simahla ziquka ukucaphukisa, ukunweba, ukubethelwa, ukugoba, ukujija, ukufuduswa, ukusika, nokufoja.

Free forging elongation

I-elongation, eyaziwa ngokuba yi-extension, yinkqubo yokubumba eyanciphisa indawo enqamlezileyo ye-billet kwaye yandisa ubude bayo.Ubude bobude buqhele ukusetyenziselwa ukubumba intonga kunye neendawo zeshaft.Zimbini iindlela eziphambili zokwandisa: 1. Ubude kwi-anvil ethe tyaba.2. Yandisa kwintonga engundoqo.Ngexesha lokubunjwa, intonga engundoqo ifakwe kwi-punched blank kwaye yolulwe njengento engenanto eqinileyo.Xa umzobo, ngokuqhelekileyo ayenziwa ngexesha elinye.Okungenanto kuqala kutsalwa kwimilo ye-hexagonal, ibunjwe ukuya kubude obufunekayo, emva koko i-chamfered kwaye ijikelezwe, kwaye intonga engundoqo ikhutshwe.Ukuququzelela ukukhutshwa kwentonga engundoqo, inxalenye esebenzayo yentonga engundoqo kufuneka ibe ne-slope ye-1: 100.Le ndlela yokwandisa inokunyusa ubude be-billet engenanto, ukunciphisa ubukhulu bodonga, kwaye igcine i-diameter yangaphakathi.Iqhele ukusetyenziselwa ukubumba uhlobo lwemikhono emide enemingxuma.

Isimahla kunye nokuphazamisa

Ukucaphukisa yinkqubo yokubumba eyanciphisa ukuphakama kwe-blank kwaye ikhulise indawo enqamlezileyo.Inkqubo ephazamisayo isetyenziselwa ukubumba izikhewu zegiya kunye nokufogiswa kweekeyiki ezijikelezayo.Inkqubo ephazamisayo inokuphucula ngokufanelekileyo i-microstructure ye-billet kunye nokunciphisa i-anisotropy yezinto eziphathekayo.Inkqubo ephindaphindiweyo yokuphazamisa kunye nokwandisa kunokuphucula i-morphology kunye nokusabalalisa i-carbides kwi-high alloy tool tool.Kukho iindlela ezintathu eziphambili zokucaphukisa: 1. Ukucaphukisa ngokupheleleyo.Ukuphazamiseka okupheleleyo yinkqubo yokubeka into engenanto kwi-anvil surface, kwaye phantsi kwempembelelo ye-anvil ephezulu, i-blank blank deformation yeplastiki kunye nokunciphisa ukuphakama kunye nokunyuka kwendawo enqamlezayo.2. Phelisa ukucaphuka.Emva kokufudumeza indawo engenanto, enye isiphelo ifakwe kwipleyiti yokuvuza okanye i-tyre mold ukukhawulela i-deformation yeplastiki yale nxalenye, kwaye enye isiphelo se-blank sibethelwa ngesando ukuze senze ukuphazamiseka.Indlela ephazamisayo yokusebenzisa iipleyiti ezingekhoyo isoloko isetyenziselwa ukuveliswa kweebhetshi ezincinci;Indlela yokuphazamisa i-mold yevili isoloko isetyenziselwa ukuveliswa kobuninzi.Ngaphantsi kweemeko zokuvelisa isiqwenga esisodwa, iindawo ezifuna ukucatshukiswa zinokuthi zifudumale kwindawo, okanye iindawo ezingafunekiyo zingacinywa emanzini emva kokufudumeza okupheleleyo, kwaye ke ukuphazamiseka kunokuqhutyelwa.3. Ukukhathazeka okuphakathi.Le ndlela isetyenziselwa ukubumba i-forging kunye necandelo elikhulu eliphakathi kunye namacandelo amancinci aphela, njengeentsimbi ezingenanto kunye nabaphathi kumacala omabini.Ngaphambi kokuphazamisa indawo engenanto, zombini iziphelo zesithuba kufuneka zitsalwe kuqala, kwaye okungenanto kufuneka kubethelwe ngokuthe nkqo phakathi kwamacwecwe amabini avuzayo ukuphazamisa indawo ephakathi kwendawo engenanto.Ukuthintela ukugoba kwe-billet ngexesha lokuphazamiseka, umlinganiselo we-billet ukuphakama h ukuya kwi-diameter dh / d ngu-≤ 2.5.

Ukubethelwa ngenqindi kwasimahla

Ukugqobhoza yinkqubo yokugaya ebandakanya ukugqobhoza okanye ukuphumela kwimingxuma kwindawo engenanto.Kukho iindlela ezimbini eziphambili zokubethelwa ngenqindi: 1. Indlela yokungqinga emacaleni amabini.Xa usebenzisa i-punch ukubetha into engenanto ukuya kubunzulu be-2 / 3-3 / 4, susa i-punch, flip i-blank, uze ulungelelanise i-punch kunye nendawo ukusuka kwelinye icala ukuze ukhuphe umngxuma.2. Indlela yokubetha ngenqindi kwicala elinye.Indlela yokubetha kwicala elinye ingasetyenziselwa iibhilithi ezinobunzima obuncinci.Xa ukubetha, i-blank blank ifakwe kwi-backing ring, kwaye isiphelo esikhulu se-punch esincinciweyo sihambelana nesithuba sokubetha.Indawo engenanto ibethelwa de umngxuma ungene.
