Ukulahlwa Centrifugal - indlela yokufumana okusilelayo oluchanileyo

ukulahlwa Centrifugal - unendlela okusilelayo lemveliso castings, olusekelwe phezu imiphumo kwemikhosi centrifugal kwi ubunzima etyhidiweyo eziphathekayo. Foundry, inxaxheba ekwenziweni okusilelayo ezimise kunye castings erhabaxa, kukho iintlobo ezininzi iindlela eyahlulayo: hlala, kwi jeli esantini-udongwe, njengomthwebeba eyahlulayo ezizodwa, phantsi koxinzelelo, njl Kodwa umgangatho wafumana ukulahlwa kangangoko uya kukudandalazisa centrifugal.

Enyanisweni, indlela sikuko ukuba amandla centrifugal umbandela olutyhidiweyo ngokufanayo kwanwenwa phezu komphezulu engaphakathi ukungunda neefom crystallizing a blank kunye parameters ezifunekayo. Musa ukucinga ukuba le ndlela isebenza kuphela isinyithi kunye aluminium zabo. Enyanisweni, bephosa iimveliso zeplastiki sele zande ngokungaqhelekanga. Kodwa iplastiki Ziliqela izinto ekufuneka ithathelwe ingqalelo xa usebenza nabo. Inaliti weplastiki kaninzi lwenziwe phantsi koxinzelelo, ebonelela iimveliso ezikhethekileyo ngqo.

Kwiimeko ezininzi, iintlobo ezahlukeneyo umtyhido zisetyenziselwa ukuvelisa castings yesinyithi. Ngenxa yoko, aphosa centrifugal zinezibonelelo ezininzi :. Akukho imigodi nomgodi inclusions zeBlack kweziphumo cast, izinto lwetshiphu emsebenzi-mninzi, ukwanda ukumelana metal ukuguga, nto leyo ifunyanwa yi isakhiwo uniform, njalo njalo okulungileyo kule ndlela zibizwa ngokuba mali eziphathekayo kwi workpiece kunye nokwehla okubonakalayo ukuntsonkotha yonke inkqubo inkqubo (ngenxa kelelo ezinintsi ephosa ukuya kwimveliso ogqityiweyo).

ukulahlwa Centrifugal lineqela "thabatha". Ezi ziquka: ukufumana engeyizizo iindawo sesisa workpiece, utyekelo sokuphelisa iifom eziphathekayo okohlukahlukana iindleko eziphezulu (ngenxa iimfuno landa okuchaneka ntathu).

oomatshini ezizodwa asetyenziswa kwi indlela ukulahlwa centrifugal. Ahluke kwicala le-axis ujikelezo - nkqo, iasi enqamlezileyo kunye ithambekele (inyaniso, elidlulileyo isetyenziswa enqabile). Imishini axis nkqo kusetyenziswa ukuvelisa billets amancinci-ubude iiyantlukwano ezingephi amanyathelo (namakhonkco, Pistons, umkhono kunye like). Oomashini nge iasi enqamlezileyo wokujikelezisa ukuvumela ukufumana ixesha elide-ubude castings eliphezulu-ngqo kunye Ebubanzini bodonga omnye. Ngokufanayo eziqulunqwe indlela kwemibhobho Yamxuluba-yentsimbi. Le ndlela yeyona common kakhulu. Ukusebenzisa ukulahlwa centrifugal unako ukuvelisa imibhobho kunye neendonga mm 80 ukuya 300 (kuxhomekeke izixhobo ezisetyenziswa). Into kuphela ukuba ngokuqinisekileyo sikhumbule kukuba ngale ndlela, uxinzelelo lwangaphakathi kwenzeka izikhewu. Ngoko ke, emva kokufumana castings kuyimfuneko ukuqhuba annealing.

indlela ukulahlwa centrifugal kwaye ilungiselelwe kwezinye iindawo preform, leyo kwenza umzimba wotshintsho. Ezithandwa kakhulu indlela ngqo ngodongwe isetyenziswa ekuvelisweni billets ukusuka zesinyithi non-ayoni (le ndlela ikuvumela ukuba ugcine izixhobo expensive).
