Enqubweni yokukhiqiza Izingxenye zedayimane, izinkinga ezihlukahlukene zizokwenzeka.Kunezinkinga ezibangelwa ukusebenza okungalungile phakathi nenqubo yokukhiqiza, kanye nezizathu ezihlukahlukene ezivela ohlelweni lokuhlanganisa ifomula nokuhlanganisa.Eziningi zalezi zinkinga zithinta ukusetshenziswa kwezingxenye zedayimane.Ngaphansi kwezimo ezinjalo, izingxenye zedayimane azikwazi ukusetshenziswa noma zingasebenzi kahle, okuthinta ukusebenza kahle kokukhiqizwa kwepuleti lamatshe futhi kwandisa izindleko zokukhiqiza.Izimo ezilandelayo zivame ukuba nezinkinga zekhwalithi ngamasegimenti edayimane:

1. Inkinga ngokucaciswa kosayizi wezingxenye zedayimane

Nakuba ingxenye yedayimane iyingxube ye-alloy yensimbi nedayimane efakwe isikhunta esingaguquki, umkhiqizo wokugcina uqedwa ngokucindezela okubandayo nokucindezela okushisayo, futhi impahla ilinganiselwe, kodwa ngenxa yokucindezela okunganele kwe-sintering kanye nokushisa kwe-sintering ngesikhathi se-sintering. ukucutshungulwa kwengxenye yedayimane, noma Ngesikhathi senqubo ye-sintering, izinga lokushisa nokucindezela kwe-insulation nokucindezela akwanele noma kuphezulu kakhulu, okuzobangela amandla angalingani engxenyeni yedayimane, ngakho-ke ngokwemvelo kuyoba nezizathu zomehluko ngosayizi. yengxenye yedayimane.Ukubonakaliswa okusobala kakhulu ukuphakama kwekhanda lokusika kanye nendawo lapho ukucindezela kunganele khona.Kuyoba phezulu, futhi ingcindezi izoba phansi kakhulu.Ngakho-ke, ohlelweni lokukhiqiza, kudingekile kakhulu ukuzinzisa ukucindezela okufanayo nokushisa.Yiqiniso, enqubweni yokulayisha ngaphambilini, ukucindezela okubandayo kwengxenye yedayimane kufanele futhi kukalwe;futhi qaphela ukuthi ungathathi isikhunta esingalungile futhi ubangele ikhanda lokusika ukuba likhishwe.Vele.Ubukhulu bengxenye yedayimane abuhlangabezani nezidingo, ukuminyana akwanele, ubulukhuni abuhlangabezani nezidingo, kukhona udoti ongqimbeni lwenguquko, futhi amandla engxenye yedayimane awanele.

2. Ukuminyana akwanele futhi ingxenye yedayimane ithambile

Enqubweni yokusika itshe ngengxenye yedayimane elicinene nelithambile, ukuphuka kwengxenye kuzokwenzeka.I-fracture ihlukaniswe ngokuhlukana okuyingxenye kanye nokuphuka okuphelele.Kungakhathaliseki ukuthi yiluphi uhlobo lokuphuka, ingxenye enjalo ayikwazi ukuphinda isetshenziswe.Yiqiniso, ukuphuka kwengxenye yedayimane kuwumkhawulo.Lapho usika itshe, ingxenye yedayimane enobuningi obanele ngeke ikwazi ukusika ngenxa yobulukhuni bayo obunganele be-Mohs, noma ikhanda lokusika lizodliwa ngokushesha kakhulu.Ngokuvamile, ukuminyana kwengxenye yedayimane kufanele kuqinisekiswe.Isimo esinjalo ngokuvamile sibangelwa izinga lokushisa le-sintering, isikhathi sokubamba, ingcindezi enganele, ukukhetha okungalungile kwempahla ye-ejenti ebophayo, okuqukethwe kwedayimane okuphezulu kwengxenye yedayimane, njll. Kuvame kakhulu ukwenzeka, futhi kuzovela nakumafomula amadala.Isizathu esijwayelekile ukusebenza okungafanele kwezisebenzi, futhi uma kuyifomula entsha, izizathu eziningi zibangelwa ukungayiqondi komklami ifomula.Umklami udinga ukulungisa kangcono ifomula yengxenye yedayimane futhi ahlanganise izinga lokushisa.Futhi ingcindezi, enikeza enengqondo kakhudlwana izinga lokushisa sintering nokucindezela.

3. Ingxenye yedayimane ayikwazi ukusika itshe

Isizathu esiyinhloko sokuthi kungani ingxenye yedayimane ingakwazi ukusika itshe kungenxa yokuthi amandla awanele, futhi amandla awanele ngenxa yezizathu ezinhlanu ezilandelayo:

1: Idayimane alanele noma idayimane elikhethiwe lisezingeni eliphansi;

I-2: Ukungcola, njengezinhlayiya ze-graphite, uthuli, njll, kuxutshwe ekhanda lokusika ngesikhathi sokuxuba nokulayisha, ikakhulukazi ngesikhathi senqubo yokuxuba, ukuxuba okungalingani nakho kungabangela lesi simo;

3: Idayimane ine-carbonized ngokweqile futhi izinga lokushisa liphezulu kakhulu, okubangela ukubola kwedayimane okubi kakhulu.Phakathi nenqubo yokusika, izinhlayiya zedayimane kulula ukuwa;

4: Idizayini yefomula yengxenye yedayimane ayinangqondo, noma inqubo ye-sintering ayinangqondo, okubangela amandla aphansi wesendlalelo sokusebenza kanye nongqimba olushintshayo (noma ungqimba olusebenzayo kanye nongqimba olungasebenzi aluhlanganisiwe ngokuqinile).Ngokuvamile, lesi simo sivame ukwenzeka kumafomula amasha;

5: Isibopho sengxenye yedayimane sithambile kakhulu noma siqine kakhulu, okuholela ekusetshenzisweni okungafani kwedayimane nensimbi, okuholela ekutheni isibopho sedayimane se-matrix singakwazi ukubamba impushana yedayimane.

4. Izingxenye zedayimane ziyawa

Kunezizathu eziningi zokuwa kwezingxenye zedayimane, njengokungcola okuningi, izinga lokushisa eliphakeme kakhulu noma eliphansi kakhulu, ukugcinwa kokushisa okufushane kakhulu kanye nesikhathi sokubamba ingcindezi, isilinganiso sefomula esingalungile, ungqimba olungenangqondo lokushisela, ungqimba oluhlukile lokusebenza kanye nefomula engasebenzi. okuholela ku-coefficient yokwandisa okushisayo kokubili Ngokuhlukile, lapho ingxenye yedayimane ipholile, ukucindezeleka kokuncipha kwenzeka kungqimba lokusebenza kanye nokuxhumeka okungasebenzi, okuzogcina kunciphise amandla ekhanda lokusika, futhi ekugcineni kubangele ingxenye yedayimane ukuba ukuwa nokunye.Lezi zizathu ziyizizathu ezenza ingxenye yedayimane iwe noma i-saw blade ilahlekelwe amazinyo.Ukuze sixazulule le nkinga, kufanele siqale siqinisekise ukuthi impushana inyakaziswa ngokugcwele ngokulinganayo futhi ngaphandle kokungcola, bese ihambisana nokucindezela okunengqondo, izinga lokushisa, kanye nesikhathi sokulondoloza ukushisa, futhi sizame ukuqinisekisa ukuthi i-coefficient yokwandisa okushisayo kwesendlalelo sokusebenza kanye nokungeyona. -ungqimba olusebenzayo lusondelene.

Ngesikhathi sokucutshungulwa kwezingxenye zedayimane, ezinye izinkinga zingase ziphakame, njengokusetshenziswa ngokweqile, ukujabha, ukugqokwa kwe-eccentric, njll. Izinkinga eziningi aziyona nje inkinga yezingxenye zedayimane, kodwa zingase zihlotshaniswe nomshini, uhlobo lwamatshe, njll. Isici sihlobene.
