Zomwe Zimayambitsa ndi Njira Zothetsera Vuto la Cemented Carbide Tool
Zoyambitsa za carbide chipping zoyambitsa ndi njira zopewera:
Kuvala ndi kutsika kwa zakudya za carbide ndi chimodzi mwa zinthu zodziwika bwino. Pamene oika carbide amavalidwa, izo zimakhudza kulondola Machining, dzuwa kupanga, workpiece khalidwe, etc.; Njira yopangira makina imawunikidwa mosamala kuti ipeze chomwe chimayambitsa kuvala kwa kuika.
1) Kusankhidwa kolakwika kwa masamba ndi mafotokozedwe, monga makulidwe a tsamba ndioonda kwambiri kapena magiredi omwe ali olimba kwambiri komanso osasunthika amasankhidwa kuti apange makina ovuta.
Zoyeserera: Wonjezerani makulidwe a tsamba kapena ikani tsambalo molunjika, ndikusankha giredi yokhala ndi mphamvu yopindika komanso yolimba.
2) Kusankhidwa kolakwika kwa zida za geometric (monga ma angle akulu kwambiri akutsogolo ndi kumbuyo, etc.).
Countermeasures: Konzaninso chida kuchokera mbali zotsatirazi. ① Chepetsani makona akutsogolo ndi akumbuyo moyenera; ② Gwiritsani ntchito kupendekera kwakukulu koyipa; ③ Chepetsani mbali yayikulu yotsika; ④ Gwiritsani ntchito chamfer yokulirapo kapena m'mphepete; ⑤ Pewani m'mphepete mwa kusintha kuti muwongolere nsonga ya chida.
3) Kuwotcherera kwa tsamba ndikolakwika, zomwe zimapangitsa kuti pakhale kupsinjika kwambiri kapena kuwotcherera ming'alu.
Njira zothanirana nazo: ①Pewani kugwiritsa ntchito poyambira mbali zitatu; ②Kusankha kolondola kwa solder; ③Pewani kugwiritsa ntchito kutentha kwa lawi la oxyacetylene powotcherera, ndipo khalani ofunda mukatha kuwotcherera kuti muchepetse nkhawa zamkati; ④Gwiritsani ntchito makina omangira momwe mungathere
4) Kunola kolakwika kudzayambitsa kupsinjika kwa kugaya ndi ming'alu yopera; kugwedezeka kwa mano pambuyo pakunola chodula cha PCBN ndi chachikulu kwambiri, kotero kuti mano amtundu uliwonse amadzaza, ndipo mpeni udzagundidwa.
Njira zothana nazo: 1. Gwiritsani ntchito kupera kwapakatikati kapena gudumu lopera la diamondi; 2. Gwiritsani ntchito gudumu lopera lofewa ndikulicheka pafupipafupi kuti gudumu lopera likhale lakuthwa; 3. Samalani ndi mtundu wa kunola ndikuwongolera mosamalitsa kugwedezeka kwa mano odula mphero.
5) Kusankhidwa kwa ndalama zodula ndizosamveka. Ngati kuchuluka kwake kuli kwakukulu, chida cha makina chidzakhala chotopetsa; podula modumphadumpha, liwiro lodula ndilokwera kwambiri, kuchuluka kwa chakudya kumakhala kokulirapo, ndipo chopereka chopanda kanthu sichiri yunifolomu, kudula kwakuya kumakhala kochepa kwambiri; kudula mkulu wa manganese chitsulo Kwa zipangizo zomwe zimakhala ndi chizolowezi chogwira ntchito mowumitsa, mlingo wa chakudya ndi wochepa kwambiri, etc.
Countermeasure: Sankhaninso kuchuluka kwa kudula.
6) Zifukwa zamapangidwe monga kutsika kwapansi kwa mpeni wa chida chomangika mwamakina kapena tsamba lalitali lotuluka.
Njira zothana nazo: ① Chepetsani pansi pa poyambira zida; ② Konzani malo a mphuno yamadzi odula bwino; ③ Onjezani gasket ya simenti ya carbide pansi pa tsamba la arbor yolimba.
7) Kuvala kwambiri kwa zida.
Countermeasures: Sinthani chida munthawi yake kapena sinthani chodulacho.
8) Kudulira kwamadzimadzi sikukwanira kapena njira yodzaza ndi yolakwika, zomwe zimapangitsa kuti tsambalo litenthe ndi kusweka.
Njira zothana nazo: ① Wonjezerani kuchuluka kwa madzi odula; ② Konzani malo odula mphuno yamadzimadzi moyenera; ③ Gwiritsani ntchito njira zoziziritsira zogwira mtima monga kuziziritsa kutsitsi kuti muzitha kuzirala; ④ Gwiritsani ntchito * kudula kuti muchepetse kukhudzidwa kwa tsamba.
9) Chidachi sichinakhazikitsidwe moyenera, monga: chida chodulira chimaikidwa pamwamba kwambiri kapena chotsika kwambiri; chodulira mphero kumatengera asymmetric pansi mphero, etc.
Countermeasure: Ikaninso chida.
10) Kukhazikika kwa dongosolo la ndondomekoyi ndi koyipa kwambiri, zomwe zimapangitsa kugwedezeka kwakukulu.
Zoyeserera: ① Wonjezerani chothandizira cha chogwirira ntchito kuti muwongolere kulimba kwa chogwiriracho; ② Chepetsani kutalika kwa chida; ③ Moyenera kuchepetsa mbali chilolezo cha chida; ④ Gwiritsani ntchito njira zina zochotsera kugwedezeka.
11) Kugwira ntchito mosasamala, monga: pamene chida chikudula pakati pa workpiece, zochitazo zimakhala zachiwawa kwambiri;
Countermeasure: Samalirani njira yogwirira ntchito.
