Ulwazi oluyisisekelo lokusika izinto ezifakiwe

  I-Dongguan Haite Tools Co., Ltd. ingumkhiqizi ochwepheshile wemikhiqizo engu-carbide inserts. Ecebile: okokufaka okusikayo, okokufaka okugaywayo kanye nezinto zokubhoboza. I-inventory eningi kanye nokulethwa okusheshayo. Njengomkhiqizi ochwepheshile wokujika wamathuluzi, namuhla sikhuluma ngezinto ezifakwa i-carbide.

1.Ukwakheka kwe-carbide insert enosimende

Njengayo yonke imikhiqizo eyenziwe abantu, ukukhiqiza cutting insert kufanele iqale ixazulule inkinga yezinto ezingavuthiwe, okuwukuthi ukunquma ukwakheka kanye nefomula yezinto ezifaka i-carbide. Iningi lokufakwa kwe-carbide lenziwe nge-carbide enosimende, izakhi eziyinhloko okuyi-tungsten carbide (WC) ne-cobalt (Co). I-WC iyizinhlayiya eziqinile kokufakwayo , futhi i-Co njenge-binder ingenza umumo wokufaka.

2.Izindlela zokushintsha izici ze-carbide enosimende insert

Indlela elula shintsha izici ze-carbide enosimende ukushintsha usayizi wokusanhlamvu wezinhlayiya ze-WC ezisetshenzisiwe. Izinto ze-carbide zikasimende ezilungiselelwe ngosayizi wezinhlayiyana ezinkulu (3-5μm) izinhlayiya ze-WC zinobulukhuni obuphansi futhi kulula ukuzigqoka; usayizi wezinhlayiyana ezincane (<1μm) izinhlayiya ze-WC zingakhiqiza ubulukhuni obuphakeme kanye nokumelana nokugqoka okungcono, Kodwa futhi i-brittle hard alloy material. Lapho ucubungula izinto zensimbi ezinobunzima obuphezulu kakhulu, ukusetshenziswa kwama-carbide blades ahlanzekile kungathola imiphumela efanelekile kakhulu yokucubungula. Ngakolunye uhlangothi, ukufakwa kwe-carbide okusanhlamvu kunokusebenza okungcono ekusikeni kwezikhawu noma okunye ukucubungula okudinga ukuqina kokufakwa okuphezulu.

Enye indlela yokulawula izici zikasimende i-carbide inserts ukushintsha isilinganiso se-WC kokuqukethwe kwe-Co. Uma kuqhathaniswa ne-WC, i-Co inobunzima obuphansi kakhulu, kodwa ukuqina okungcono. Ngakho-ke, ukunciphisa okuqukethwe kwe-Co kuzoholela ekufakweni kokuqina okuphezulu. Yiqiniso, iphinda iphakamise umbuzo webhalansi jikelele: ukufakwa kokuqina okuphezulu kunokumelana nokugqoka okungcono, kodwa ukuqina kwayo nakho kukhulu. Ngokohlobo oluthile lokucubungula, ukukhetha usayizi wokusanhlamvu we-WC ofanele kanye nesilinganiso sokuqukethwe kwe-Co kudinga ulwazi olufanele lwesayensi nolwazi olucebile lokucubungula.

3.Indima ye-carbide insert coating

Ngokusebenzisa ubuchwepheshe be-gradient material , ukuvumelana phakathi kwamandla okufaka nokuqina kungagwenywa ngezinga elithile. Lobu buchwepheshe obuvame ukusetshenziswa abakhiqizi abakhulu bamathuluzi bomhlaba wonke buhlanganisa ukusetshenziswa kwesilinganiso esiphezulu sokuqukethwe kwe-Co kungqimba yangaphandle ye- carbide insert kunesendlalelo sangaphakathi. Ngokucacile, ukukhulisa okuqukethwe kwe-Co kungqimba olungaphandle (ubukhulu obungu-15-25μm) bokufakwa kwe-carbide ukuze kuhlinzekwe umphumela "wesibhafa", ukuze ukufakwa kwe-carbide kukwazi ukumelana nomthelela othile ngaphandle kokuphuka. Lokhu kuvumela umzimba wokufaka i-carbide ukuthi uthole izici ezihlukahlukene ezinhle kakhulu ezingafinyelelwa kuphela ngokusebenzisa izingxenye ze-carbide ezisikiwe ezinamandla aphezulu.

4.Inqubo yokukhiqiza yokusika izinto ezifakiwe

Uma sekukhona imingcele yobuchwepheshe njengosayizi wezinhlayiyana nokwakheka kwe impahla eluhlaza inqunywa, inqubo yokukhiqiza yangempela yokufaka ukusika ingaqalwa. Okokuqala, faka impushana ye-tungsten, i-carbon powder, ne-cobalt powder ngezilinganiso emshinini wokugaya olingana nomshini wokuwasha, ugaye impushana ibe usayizi wezinhlayiyana ezidingekayo, bese uhlanganisa izinto ezihlukahlukene ngendlela efanayo. Utshwala namanzi kwengezwa ngesikhathi sokugaya ukuze kulungiswe udaka olumnyama oluwugqinsi. Khona-ke udaka lufakwa emshinini wokomisa isishingishane, futhi ngemva kokuba uketshezi olukulo seluhwamukile, kutholwa impushana ehlanganisiwe bese igcinwa.

Enqubweni elandelayo yokulungiselela, isibonelo sika-i-carbide insert singatholakala. Okokuqala, hlanganisa i-powder elungisiwe ne-polyethylene glycol (PEG). I-PEG isebenza njenge-plasticizer ukuze ihlanganise impushana ndawonye njengenhlama. Izinto ezisetshenziswayo zibe sezicindezelwa esimweni sokushutheka esikhunjeni sokucindezela. Ngokwezindlela zokucindezela ezihlukene ze-carbide, umshini wokucindezela we-axis eyodwa ungasetshenziselwa ukucindezela, noma umshini wokucindezela we-multi-axis ungasetshenziswa ukuze ucindezele umumo wokufaka i-carbide kuma-engeli ahlukene.

Ngemva kokuthola icindezelwe ingenalutho, ifakwa esithandweni esikhulu somlilo futhi sishiswe ekushiseni okuphezulu. Phakathi nenqubo yokucwilisa, i-PEG iyancibilika futhi ikhishwe kungxube engenalutho, futhi ekugcineni i-semi-finished carbide insert isala. Lapho i-PEG incibilika, ukufakwa kwe-carbide kuncipha kuze kufike kusayizi wayo wokugcina. Lesi sinyathelo senqubo sidinga izibalo ezinembile zezibalo, ngoba ukuncipha kokufakwa kwe-carbide kuyahlukahluka ngokuya ngenhlanganisela yezinto ezibonakalayo nezilinganiso, futhi ukubekezelelana komkhiqizo oqediwe kuyadingeka ukuthi kulawulwe ngaphakathi kwama-microns ambalwa.
