Ya kamata a zabi sansanonin granite don kayan aikin shigarwa na mold?

A cikin aiwatar da gyaran gyare-gyare da samarwa, ginin granite yana aiki kamar "stabilizer" don kayan aiki, yana tasiri kai tsaye da daidaiton shigarwa na ƙirar da ingancin samfurin. Don haka, yadda za a zabi tushen granite daidai?

Da farko dai, daidaito shine mabuɗin. Mold shigarwa yana da musamman high ainihin bukatun. Ya kamata a biya kulawa ta musamman ga flatness da madaidaiciyar tushe. Babban ingancin granite tushe yana da lebur a cikin ± 0.5μm / m kuma kuskuren madaidaiciyar da bai wuce ± 0.3μm/m ba. Kamar gina ginin tare da tubalan, mafi girman tushe shine, za a shigar da ƙirar daidai daidai, kuma girman samfuran da aka samar za su kasance cikin layi tare da ma'auni.

Na biyu, ba za a iya yin watsi da ƙarfin ɗaukar kaya ba. Nauyin nau'i daban-daban ya bambanta sosai. Karamin ƙwayar allura na iya yin nauyi ƴan kilogiram ɗari kacal, yayin da babban simintin simintin gyare-gyare zai iya auna tan da yawa. Lokacin zabar tushe, yana da mahimmanci don dacewa da ƙarfin ɗaukar nauyi dangane da nauyin nau'in ƙirar kuma a ajiye iyakar aminci na 20% zuwa 30%, kamar siyan shiryayye tare da mafi girman ƙarfin ɗaukar nauyi don hana wuce gona da iri da lalacewa.

Bugu da ƙari, rawar jiki yana faruwa a lokacin sarrafa ƙwayar cuta, wanda ke buƙatar tushe don samun kyakkyawan aikin damping vibration. Granite a dabi'a yana da kyawawan kaddarorin damping kuma yana iya ɗaukar sama da kashi 90% na girgiza mai ƙarfi. Zaɓin tushe tare da rabon damping sama da 0.02 na iya rage tasirin fiɗa a saman ƙera kuma sanya saman samfurin ya zama santsi.

Har ila yau, dacewa da shigarwa yana da mahimmanci. Bisa ga hanyar gyarawa na mold, zaɓi tushe tare da T-ramukan da suka dace da ramukan zaren. Idan gyaggyarawa ce mai siffa ta musamman, ana iya gyara tushe mai sifar da ba ta dace ba. Har ila yau, idan aka yi la'akari da yanayin da ake sarrafawa, idan ya haɗu da sinadarai irin su coolant, granite da aka yi amfani da shi don hana lalacewa ya kamata a zaba don hana tushe daga lalacewa.

Muddin kun mallaki waɗannan mahimman mahimman bayanai, zaku iya zaɓar tushen granite wanda ya dace da kayan aikin ƙirar ƙira, yana tabbatar da ingantaccen samarwa!
