Kubaluleke kakhulu ukuhlola ubulukhuni besiqeshana sokusebenza sehange. Isiqeshana sidinga ukuba nobunzima obuthile ngesikhathi sokusetshenziswa ukuze kuqinisekiswe ukwethembeka nokuqina komsebenzi waso. I-Laihua Company ingakwazi ukwenza ngokwezifiso izinsimbi ezikhethekile ezihlukene ngokwezidingo, futhi ingasebenzisa umhloli wokuqina we-Laihua ukuhlola ubulukhuni.
Izinga lokuhlola ubulukhuni bekliphu ye-ancho ngokuvamile libhekisela ku:
1. Rockwell ubulukhuni GB/T 230.1-2018
Leli zinga lisebenzisa indlela yokuhlola ubulukhuni be-Rockwell kanye nesikali sobulukhuni se-HRC Rockwell ukuze sihlolwe, Le ndlela yokuhlola ilula ukuyisebenzisa futhi iyisinqumo esifanele amakhasimende.
2. Brinell ubulukhuni GB/T231.1-2018.
Leli zinga lisebenzisa isikali sokuqina kwe-Brinell HB ukuhlola.
Izinga lokuhlola libhekisele ku:
I-GB/T 14370-2015 noma i-JT/T 329-2010.
Ngenxa yemininingwane yokuma kwesiqeshana sehange, ngokuya ngosayizi wekhasimende we-clip taper kanye nosayizi we-diameter yangaphakathi yokunamathisela, lapho uthenga isihloli sokuqina, kuyadingeka ukwenza ngendlela oyifisayo amathuluzi ochwepheshe njengoba kudingekile ukuze kuqinisekiswe ukunemba kwevelu elilinganisiwe nokunwetshwa. impilo yesevisi yomhloli wokuqina. Uma kunesidingo, sicela ukhululeke ukuthumela amasampula ukuze ahlolwe.
Indlela yokuhlola ukuqina kokuphuka kwamathuluzi e-carbide enosimende ngobulukhuni be-Vickers (sebenzisa i-Vickers tester hardness):
Ubulukhuni be-carbide enosimende ngokuvamile kufanele buhlolwe kusetshenziswa isikali se-Rockwell hardness A. Uma ubukhulu bocezu lokusebenza noma isampula bungaphansi kuka-1.6 mm, indlela yokuqina ye-Vickers ingasetshenziswa ukuhlola. Ngakho-ke iyiphi indlela yokuhlola ukuqina kokuphuka kwamathuluzi e-carbide enosimende?
Indinganiso yokuhlolwa kokuqina kokuphuka kanye nendlela yokuhlola ukuqina kokuphuka kwesisekelo sezinto eziyisisekelo zethuluzi le-carbide: JB/T 12616—2016;
Indlela yokuhlola imi kanje:
Okokuqala, yenza ucezu lokusebenza oluzohlolwa lube isampula, bese upholisha ingaphezulu lesampula endaweni yesibuko, bese uyibeka ngaphansi kwesihloli sokuqina kwe-microhardness ukuze ukhiqize i-indent endaweni epholishiwe nge-conical indenter yedayimane yesihloli sokuqina, ukuthi imifantu eyenziwe ngaphambilini yenziwa kuma-vertices amane e-indent.
Inani lokuqina kwe-fracture (KIC) libalwa ngokusekelwe kumthwalo wokuhlehlisa wokuhlehlisa ongu-P kanye nobude besandiso sesandiso sokuhlehla sokuhlehlisa esingu-C.
I-Laizhou Laihua Testing Instrument Factory ihlale ikhona ukuze uphendule noma yimiphi imibuzo onayo.
