Ukwakhiwa kwevili lokufaka amanqaku e-YG6X carbide ikakhulu kubandakanya ezi ndawo zilandelayo:
1. Umxholo wentsimbi engundoqo:
I-WC (i-tungsten carbide): i-93.5% okanye i-94%, iyona nxalenye ephambili ye-YG6X ye-cemented carbide, emisela ubulukhuni bayo kunye nokumelana nokugqoka.
I-Co (cobalt): I-6%, i-binder ebalulekileyo ye-YG6X ye-cemented carbide, enokuphucula ukuchasana kwempembelelo kunye nokuqina kwe-alloy.
2. Umxholo wokungcola:
I-Ni (nickel) kunye nezinye izinto ezingcolileyo: umxholo ophantsi, ngokuqhelekileyo awukho ngaphezu kwe-0.5%.
3. Iimpawu zoomatshini:
Ubuninzi: malunga ne-14.5-15.0g/cm³.
Ubunzima (HRA): inokufikelela kwi-91 okanye i-90HRA okanye ngaphezulu.
Amandla e-Flexural (σbb/MPa): malunga ne-1400-1500MPa.
Ukuqina kwempembelelo σK/(J/cm²): 2.5.
I-Machining carbide scoring wheels yinkqubo ebandakanya amanyathelo amaninzi kunye neenkcukacha. Nantsi inkqubo ecacileyo edibanisa ulwazi olufanelekileyo olusuka kwinqaku lereferensi:
Okokuqala, ukulungiselela kwangaphambili
Ukulungiswa kwemivalo ye-alloy: khetha imivalo enobunzima obufanelekileyo ngokweemfuno zomthengi. I-carbide ene-cemented yenziwe nge-tungsten carbide, i-titanium carbide kunye nezinye isinyithi njengesigaba esinzima, i-cobalt kunye nezinye izinyithi njenge-binder, ngokusebenzisa indlela ye-metallurgy yomgubo, kunye nobunzima obuphezulu kunye ne-thermal conductivity ephantsi.
Ukukhethwa kwekhadi lenkqubo: ukusika ngokwekhadi lenkqubo ehambelanayo ukuqinisekisa ukuba izinto eziphathekayo zihlangabezana neemfuno zokucubungula.
Okwesibini, inkqubo yokucubungula
Ukucinezela: Ucofa ngeepuntshi kwaye ufe kumatshini wokushicilela ozenzekelayo ukufumana iimilo ezisisiseko kunye nemilinganiselo. Eli nyathelo ngundoqo ekuqinisekiseni ubume besiseko sevili lokufaka amanqaku.
I-Sintering: Ngokusebenzisa inkqubo ye-sintering, i-cobalt enyibilikisiweyo idityaniswe ne-tungsten carbide particles, eqhubela phambili ukuqinisa ubunzima kunye nokuzinza kwevili lokulinganisa.
Ukugaya: Idayimane yokusila isetyenziselwa ukunika i-carbide ifake imilo echanekileyo. Ngethuba lenkqubo yokugaya, kuyimfuneko ukukhetha ivili lokugaya elichanekileyo kunye neeparitha zokugaya ukuphepha ukugqoka izixhobo kunye nokulahlekelwa komgangatho owenziwe ngomatshini. Ngexesha elifanayo, kuyimfuneko ukubeka ingqalelo kwisehlo sokuqhekeka kokusila, okuvame ukubangelwa ukunyanzeliswa koxinzelelo olwenziwe phezu kwesixhobo esidlula umda we-tensile wezinto eziphathekayo. Ngoko ke, umthombo woxinzelelo lwe-tensile kufuneka ulawulwe ngokungqongqo ngexesha lenkqubo yokusila.
Ukusika unyango: Umgca wokusika uphathwa ukuze ufumane imilo echanekileyo ukufezekisa ukunyanzeliswa kokunxiba okufunekayo kumatshini. Eli nyathelo liyimfuneko ekuphuculeni ukusebenza kokusika kunye nokuqina kwevili lokusika.
Okwesithathu, emva kokulungiswa
Ukwaleka: Ukubekwa komphunga wekhemikhali kunye nokubekwa komphunga obonakalayo ziindlela ezimbini zokwaleka ezikhoyo, ngokuxhomekeke kwizinto kunye nendlela yokucubungula. Ukugquma kunokunyusa ukunyanzeliswa kokunxiba kunye nokuxhathisa ukubola kwevili lokufaka amanqaku, ukwandisa ubomi bayo benkonzo.
Ukuhlolwa komgangatho: Ukuhlolwa komgangatho wevili le-carbide cutter elicutshungulwayo elicutshungulwayo liyenziwa ukuze kuqinisekiswe ukuba lihlangabezana neemfuno zoyilo kunye neemfuno zokusetyenziswa.
Okokuqala, iZithintelo
Ngethuba lenkqubo yonke yokucubungula, kuyimfuneko ukubeka ingqalelo ekusebenzeni okukhuselekileyo ukuphepha iingozi.
Lawula ngokungqongqo iiparameters zokucubungula kunye neemfuno zenkqubo ukuqinisekisa umgangatho kunye nokusebenza kwevili lokufaka amanqaku.
Jonga rhoqo ubume bezixhobo kunye nezixhobo, kwaye utshintshe iindawo ezinxitywe kakhulu ngexesha ukuqinisekisa ukuchaneka komatshini kunye nokusebenza kakuhle.
Ngokuphunyezwa ngokungqongqo kwamanyathelo angentla kunye nezilumkiso, umgangatho ophezulu we-machining kunye nokusebenza kwexesha elide levili lokulinganisa i-carbide linokuqinisekiswa.
