Indlela yokuvelisa iincakuba zeesarha zedayimani ezisebenza kakhulu zahluke kakhulu kwiincakuba zesarha zedayimani zemveli, Ezi zilandelayo ziya kwazisa iimpawu zesarha yedayimane ekumgangatho ophezulu kwaye yazise amanqaku aliqela ekufuneka aqwalaselwe kwinkqubo yokuvelisa.

1: Ibakala ledayimani kufuneka likhethwe. Ngoko ke luhlobo luni lwedayimani olulungileyo? Ekubeni kunzima ukulawula imilo yemveliso yokugqibela ngexesha lokuveliswa kweedayimani zokwenziwa, iidayimani ezininzi zinezakhiwo zepolygonal ezingaqhelekanga. Ubume bepolygonal bubukhali kunesakhiwo se-tetrahedral, kodwa le dayimani iveliswa ngaphantsi. Idayimani esetyenziswa ngokuqhelekileyo kwiincakuba zeesarha yidayimane eyihexahedral. Ke ngoko yintoni umahluko phakathi kwedayimani yomgangatho ophantsi kunye nedayimani yomgangatho ophezulu wedayimani? Iidayimani ezikumgangatho ophantsi ziyi-octahedral okanye i-faceted structure, Kwinkqubo yokwenyani yokusika, ngenxa ye-chestnut yamanzi enkulu yokusika eyenziwe ngobuso bedayimane nganye, ukukwazi ukusika akukwazi ukugqanyiswa. Kakade ke, ukuba kukho iingxaki ezithile ngedayimane ezibangelwa ubushushu okanye uxinzelelo ngexesha lenkqubo yokuvelisa. Okanye ukufakwa kwedayimani okwesibini kuya kukhokelela kwiipropathi ezingazinzanga zedayimani, ezinje ngokuqina okuphezulu kunye nobunzima obaneleyo. Ke ngoko, ukukhetha umgubo wedayimani onetetrahedra eninzi kangangoko kuyimfuneko ebalulekileyo ekwenzeni iisaha zedayimane ezikumgangatho ophezulu.

I-2: I-particle size imodareyitha, i-diamond ye-Coarse-grained inenzuzo yobuchule bokusika obuqinileyo kunye nomgangatho ophezulu wokusika, okufuneka ube ne-high-efficiency saw blades. I-particle fine saw blade ineempawu zokugaya okongeziweyo, ukusetyenziswa okuncinci kunye nokusabalalisa. Ngethuba lenkqubo yokusika, iindawo ezingenakunqunyulwa yi-diamond e-coarse-grained ziyakwazi ukuxhaswa kunye nomhlaba, kwaye idayimane ayiyi kuhlanjululwa ngokukhawuleza ngenxa yempembelelo, eya kubangela inkunkuma enkulu. Ngaphezu koko, ukusetyenziswa okufanelekileyo kweengqungquthela ezinqabileyo kunye ezintle, ezibalwe ngokobuninzi bobuninzi, kunokunyusa ngokukhawuleza ukuxinwa kwedayimane ukuya kwinqanaba elithile. Ngokubanzi, nangona iidayimani ezicolekileyo ziluncedo kakhulu ekunciphiseni ukusebenza kakuhle. Nangona kunjalo, ukongeza iidayimani ezicolekileyo ngokufanelekileyo ukuze zihambelane neepowders ezirhabaxa kunye nezicolekileyo ziya kwenza i-saw blade ibe yindleko ngakumbi ngexesha lenkqubo yokusika, kwaye akuyi kubakho imeko apho iidayimani ezinobuncwane azikwazi ukunqunyulwa emva kokuba umhlaba uphantsi.

3: Uzinzo olungcono lwe-thermal. Kwinkqubo yokuvelisa idayimani, igraphite icutshungulwa ngubushushu obuphezulu kunye noxinzelelo oluphezulu. Igrafu yobushushu obuphezulu yenza amasuntswana omgubo wedayimani kwindawo eneempawu. Enyanisweni, iidayimani ezininzi kwindalo zinozinzo olufanayo lwe-thermal. Nangona kunjalo, kuye kwacatshangelwa ukuba ukuba ukuzinza kwe-thermal kwedayimani kwanda, ukusebenza kwedayimani kunokunyuswa. Ke ngoko, abantu bafezekisa injongo yokunyusa ukuzinza kwe-thermal ngokusebenzisa i-titanium plating. Zininzi iindlela zokubeka i-titanium, kubandakanywa ukubethelwa kwe-titanium, kunye ne-titanium plating kusetyenziswa iindlela zemveli zokubeka i-titanium. Kubandakanywa nokuba imeko ye-titanium plating iqinile okanye i-liquid, njl., inempembelelo enkulu kwisiphumo sokugqibela se-titanium plating.

I-4: Ukwandisa amandla okusika i-diamond saw blade ngokunyusa amandla okubamba. Kwafunyaniswa ukuba i-carbon eyomeleleyo inokwenza ngokuthe ngqo isakhiwo esizinzileyo phezu kwedayimani, eyaziwa ngokuba yi-carbon compound eyomeleleyo. Izinto zetsimbi ezinokuthi zenze iikhompawundi ezinjalo ngedayimane, kubandakanywa izinto zetsimbi ezifana ne-plating, i-titanium, i-chromium, i-nickel, i-tungsten, njl njl. Kukho iintsimbi ezifana ne-molybdenum, enokuphucula ukumanzi kwedayimani kunye nezi zinyithi, kunye nokwandisa ukubamba. amandla edayimani ngokwandisa ukumanzisa.

I-5: Ukusetyenziswa kwe-ultra-fine powder okanye i-powder prefabricated alloy powder inokunyusa ukuzinza kwebhondi. Okukhona umgubo ucotha, kokukhona ukomelela kokumanzisa phakathi komgubo wentsimbi nganyekunye nedayimane ngexesha le-sintering, Iphinda igweme ukulahleka kunye nokwahlulwa kwentsimbi ephantsi yokunyibilika kwiqondo lokushisa eliphantsi, elingenako ukuphumeza umphumo wesinyithi kunye nee-agent zokumanzisa, ezinciphisa kakhulu umgangatho wokusika kunye nokuzinza kwe-matrix ye-diamond saw blade.

I-6: Yongeza inani elifanelekileyo lezinto ezinqabileyo zomhlaba (ezifana ne-lanthanum yomhlaba enqabileyo, i-cerium, njl.) kwi-matrix powder. Inokunciphisa kakhulu ukunxiba kwe-diamond cutter head matrix, kwaye inokuphucula ukusebenza kakuhle kwe-diamond saw blade (ukusebenza okucacileyo kukuba xa ubukhali buphuculwe, ubomi be-saw blade buyancipha kancinci).

I-7: I-vacuum yokukhusela i-sintering, oomatshini abaqhelekileyo be-sintering bafakwe kwimo yendalo. Le ndlela ye-sintering ivumela ukuba icandelo livezwe emoyeni ixesha elide. Ngethuba lenkqubo ye-sintering, icandelo lixhomekeke kwi-oxidation kunye nokunciphisa ukuzinza. Nangona kunjalo, ukuba intloko ye-cutter ifakwe kwindawo ye-vacuum, inokunciphisa i-oxidation yecandelo kwaye iphucule kakhulu ukuzinza kwecandelo.

8: Sintering ngundo omnye. Ngokomgaqo osebenzayo womatshini wokucofa oshushu wangoku, eyona ndlela ingcono kukusebenzisa i-single-mode sintering. Ngale ndlela, ngexesha lenkqubo ye-sintering, umehluko wokuzinza phakathi kweengqimba eziphezulu kunye nezantsi zecandelo lincinci, kwaye i-sintering ifana. Nangona kunjalo, ukuba i-sintering yeendlela ezimbini okanye i-four-mode sintering isetyenzisiwe, ukuzinza kwe-sintering kuya kuncitshiswa kakhulu.

I-9: I-Welding, ngexesha le-welding, Ukuzinza kweepads ze-solder zesilivere ziphezulu kakhulu kunezobhedu zobhedu. Ukusetyenziswa kweepads zesilivere ezinomxholo wesilivere we-35% kuncedo olukhulu kumandla okugqibela we-welding ye-saw blade kunye nokuchasana kwempembelelo ngexesha lokusetyenziswa.

Isishwankathelo, ii-saw blades eziphezulu zinika ingqalelo kwiinkcukacha ezininzi kwinkqubo yokuvelisa. Kuphela ngokulawula ngononophelo zonke iinkalo zokuthengwa kwempahla, imveliso, i-post-processing kunye nomnye umsebenzi onokuthi kwenzeke ukwenza imveliso yedayimane ebalaseleyo.
