Ma'auni don zaɓin sigogi na kayan gani na lu'u-lu'u

1. Zaɓin girman ƙwayar lu'u-lu'u
Lokacin da girman lu'u-lu'u ya yi girma kuma bai yi ɗaya ba, kan ruwa yana da kaifi kuma aikin yankan yana da girma, amma ƙarfin lanƙwasawa na agglomeration lu'u-lu'u yana raguwa.Lokacin da granularity lu'u-lu'u yana da kyau ko gauraye, shugaban tsinken gani yana da babban karko amma ƙarancin inganci.Yin la'akari da abubuwan da ke sama, girman lu'u-lu'u 50/60 ya dace.
2. Zaɓin ƙaddamarwar rarraba lu'u-lu'u
A cikin wani takamaiman kewayon, lokacin da maida hankali na lu'u-lu'u ya canza daga ƙasa zuwa babba, ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun igiyar gani yana raguwa a hankali, amma rayuwar sabis ɗin sannu a hankali tana ƙaruwa.Amma idan maida hankali ya yi yawa, ruwan zai yi duhu.Yin amfani da ƙananan hankali, ƙananan ƙwayar hatsi, za a inganta ingantaccen aiki.Yin amfani da sassa daban-daban na shugaban kayan aiki a cikin sawing, ta yin amfani da nau'i daban-daban (wato, a cikin nau'i uku ko fiye na tsarin tsarin tsakiya na tsakiya za a iya amfani da shi don rage maida hankali), tsarin aikin ganuwar yana aiki akan samuwar. na tsakiyar tsagi, conducive don hana saw ruwa pendulum, don inganta ingancin dutse aiki.
3. Zaɓin ƙarfin lu'u-lu'u
Ƙarfin lu'u-lu'u shine mahimmancin mahimmanci don tabbatar da aikin yankewa.Ƙarfin da yawa zai sa crystal ba sauƙin karya ba, ƙwayoyin abrasive suna gogewa a amfani da su, raguwa yana raguwa, yana haifar da lalacewar kayan aiki;Lokacin da ƙarfin lu'u-lu'u bai isa ba, yana da sauƙi a karye bayan tasiri kuma yana da wuyar ɗaukar nauyi mai nauyi na yanke.Don haka, ya kamata a zaɓi ƙarfin a cikin 130 ~ 140N.4. Zaɓin lokacin haɗin gwiwa
Ayyukan ƙwanƙwasa saw sun dogara ba kawai a kan lu'u-lu'u ba, amma har ma a kan aikin gabaɗaya na kayan haɗin gwiwar da aka kafa ta hanyar haɗin da ya dace na lu'u-lu'u da ɗaure.Don marmara da sauran dutse mai laushi, kayan aikin injiniya na kayan aikin kayan aiki yana da ƙananan ƙananan, zai iya zaɓar mai ɗaure tushe na jan karfe.Amma sinterin zafin jiki na jan karfe tushe mai ɗaure yana da ƙasa, ƙarfi da taurin suna da ƙasa, ƙarfi yana da girma, kuma ƙarfin haɗin gwiwa tare da lu'u-lu'u yana da ƙasa.Lokacin da aka ƙara WC, WC ko W2C ana amfani dashi azaman kwarangwal, tare da adadin da ya dace na cobalt don inganta ƙarfi, taurin da halayen haɗin kai, da ƙaramin adadin Cu, Sn, Zn da sauran ƙananan ƙarfe masu ƙarancin narkewa da taurin suna. kara a matsayin bonding lokaci.Girman barbashi na babban abin ƙara ya kamata ya zama mafi kyau fiye da raga 200, kuma girman barbashi na ɓangaren ƙara ya kamata ya zama mafi kyau fiye da raga 300.
5. Zaɓin tsarin sintiri
Tare da haɓakar zafin jiki, matakin densification na gawa yana ƙaruwa, haka ma ƙarfin lanƙwasawa.Koyaya, tare da tsawaita lokacin riƙewa, ƙarfin lanƙwasawa na gawa mara kyau da lu'u-lu'u agglomeration na farko yana ƙaruwa sannan kuma yana raguwa.A sintering tsari na 120s a 800 ℃ za a iya zaba don saduwa da yi bukatun.
