Tsarin Kera na Tungsten Carbide Niƙa Quills: Daga Foda zuwa Kayan Aikin Madaidaici

Tungsten carbide nika quills kayan aiki ne masu mahimmanci a fagen niƙa mai tsayi, kuma aikinsu na musamman ya samo asali ne daga ingantattun hanyoyin masana'antu. Tafiya daga ƙananan foda-matakin foda zuwa kayan aiki na daidaitaccen aiki ya ƙunshi jerin tsari mai kulawa sosai.

Raw Material Proportioning and Mixing

Ana farawa da masana'anta da a hankali zaɓaɓɓen tungsten carbide foda da foda cobalt. Cobalt yana aiki azaman lokacin ɗaure, kuma abun cikin sa kai tsaye yana shafar taurin samfurin ƙarshe da taurinsa. Yawanci, abun ciki na cobalt yana jere daga 6% zuwa 12%, daidai gwargwado daidai da takamaiman buƙatun aikace-aikacen. Waɗannan foda masu ƙananan matakan suna jika-haɗe a cikin injinan ƙwallo don tabbatar da rarraba iri ɗaya na matakin kwayoyin halitta.

Tsari Tsari

An fesa gauraye slurry a cikin granules masu gudana kyauta. Daga baya, ana amfani da fasaha mai matsi na isostatic mai sanyi don matsawa kayan a matsa lamba 200-300 MPa. A wannan mataki, ainihin siffar geometric na shinge na niƙa na carbide an kafa shi, amma ƙarfin ya kasance ƙasa, yana buƙatar ƙarin aiki.

Tsari Tsari

Sintering shine ainihin tsari na tsarin masana'antu. A cikin tanderun da ba za a iya cirewa ba, ana sarrafa zafin jiki daidai sama da wurin narkewar cobalt (yawanci 1400-1500 ° C). A wannan lokaci, lokacin cobalt yana narkewa kuma yana jika barbashi na tungsten carbide, yana samar da haɗin gwiwa mai yawa ta hanyar sarrafa lokaci na ruwa. Madaidaicin kulawar yanayin dumama da riƙe lokaci yana da mahimmanci don tabbatar da cikakkiyar ƙima da sarrafa ci gaban hatsi.

Daidaitaccen Machining

Mashin niƙa mara kyau na carbide mara kyau yana shiga daidai matakin injin, wanda ke da mahimmanci don tabbatar da niƙan ya cika buƙatun amfani. An fara aiwatar da mashin ɗin mashin ɗin ta amfani da madaidaicin madaidaicin cylindrical grinders tare da ƙafafun niƙa lu'u-lu'u don kafa ingantacciyar axis, tare da jure juzu'i masu sarrafawa tsakanin ± 0.01 mm.

Mahimman hanyoyin niƙa maɓalli sun haɗa da:

1. Tool shank aiki: Yin amfani da high ainihin grinders tare da lu'u-lu'u ƙafafun, shafe m nika, Semi-karewa, da kuma karewa. M nika yana kawar da wuce haddi abu, Semi-kammala cimma girma bukatun, da kuma kammala tabbatar da roughness surface Ra ≤ 0.2 μm. Haƙuri na kusurwa na Taper don HSK, CAPTO, da sauran musaya dole ne su kasance cikin ± 30”.

2. Gyaran rami mai sanyaya: Yin amfani da kayan aikin hako rami mai zurfi tare da fasahar hako bindiga. Don tabbatar da ingancin bangon rami, saurin ciyarwa (yawanci 50-100 mm/min) da matsa lamba mai sanyaya (10-15 MPa) dole ne a sarrafa shi daidai. Daidaitaccen diamita na rami dole ne ya kai darajar H7, tare da kuskuren madaidaiciyar da bai wuce 0.02/100 mm ba.

3. Dynamic daidaitawa: Yin amfani da na'urori masu daidaitawa na musamman don daidaita yawan rarraba ta hanyar cire kayan aiki. Bukatun sun haɗa da cimma ma'auni na G2.5 tare da ragowar rashin daidaituwa ƙasa da 1 g·mm/kg a matsakaicin saurin aiki.

Duban inganci

Binciken ƙarshe ya haɗa da daidaita injunan auna don ma'auni na geometric, interferometers na laser don tsari da haƙurin matsayi, injunan daidaitawa don gwajin ma'auni mai ƙarfi, da microscopes na ƙarfe don nazarin tsarin kayan. Samfuran da suka wuce duk gwaje-gwaje masu tsauri kawai za a iya isar da su.

Dukan tsarin masana'antu ya haɗa fasahar fasaha da yawa ciki har da foda karfe, mashin daidaici, da maganin zafi. Daidaitaccen sarrafawa a kowane mataki tare yana ba da gudummawa ga keɓaɓɓen aikin tungsten carbide niƙa quills. Musamman a cikin madaidaicin lokaci machining, cikakken aikace-aikacen fasahar kayan aiki mai ƙarfi, madaidaicin fasahar aunawa, da fasahar sarrafawa mai sarrafa kansa yana tabbatar da daidaiton ƙirar ƙananan matakan.
