Umhloli we-Leeb Hardness
Njengamanje, i-Leeb Hardness Tesser isetshenziswa kabanzi ekuhlolweni kokuqina. Umhloli we-Leeb Hardness Amukeliswa umgomo wokuhlola kanzima kanzima futhi usebenzisa ubuchwepheshe bekhompyutha ukuze aqaphele i-miniaturization kanye ne-elektroniki kagesi Kulula futhi kulula ukuyisebenzisa, ukufunda kuyinto enembile ngokwengeziwe, futhi imiphumela yokuhlola ingaguqulwa kalula ibe amanani alukhuni we-Brinell, ngakho-ke ukwamukelwa kabanzi.
Izinkomba eziningi zingama-medium-to-arping Ukuhlolwa okunembile kobuqili bokusebenzisa imali esetshenziswa ngokuhlukile noma amabhlogo wokuhlola anamathele ku-castings. Kodwa-ke, i-test bar noma ibhulokhi yokuhlola ingangena esikhundleni salo msebenzi uqobo. Noma ngabe kuyisitayela esifanayo sensimbi encibilikisiwe, inqubo yokuphonsa kanye nezimo zokwelapha ukushisa ziyefana. Ngenxa yomehluko omkhulu ngosayizi, isilinganiso sokushisa, ikakhulukazi inani lokupholisa, lizohluka. Kunzima ukwenza laba bobabili banobunzima obufanayo. Ngalesi sizathu, amakhasimende amaningi akhathalela ngokwengeziwe futhi akholelwe ngobulukhuni bendawo yokusebenza uqobo. Lokhu kudinga umhloli we-hardness oyindida wokuqonda ukuze ahlole ubunzima bokukhishwa kwemali. I-Leeb Hardness Tenter ixazulula le nkinga, kepha kuyadingeka ukunaka ukuqedwa komhlaba wokuqeda umsebenzi ngesikhathi sokusetshenziswa kwe-Leeb Harveness Tester. I-Leeb Hardness Tesser inezidingo zobubi bendawo yokusebenza.
Umhloli we-Brinell Hurness
Umhloli we-Brinell Hurneness kufanele asetshenziselwe ukuhlolwa kanzima kwezinkonsa. Okwezinkonzo zensimbi ezimpunga ezinama-rains ahlukahlukene, izimo zokuhlola ze-3000kg Force ne-10mm ibhola kufanele zisetshenziswe ngangokunokwenzeka. Lapho usayizi wokuphonsa ubuncane, umhloli wobulukhuni we-rocwell nawo angasetshenziswa.
Ama-Iron Castings ajwayele ukwakheka okungalingani, okusanhlamvu okukhudlwana, futhi aqukethe ikhabhoni engaphezulu, i-silicon nokunye ukungcola kwensimbi, futhi ubunzima buzohluka ngezindawo ezincane ezihlukile noma ngamaphoyinti ahlukene. I-Indenter of the Brinell Hurneness Proper inosayizi omkhulu kanye nendawo enkulu yokuqamba kabusha, futhi ingalinganisa inani elijwayelekile lobulukhuni obungokwenyama ngaphakathi kwebanga elithile. Ngakho-ke, umhloli we-Brinell Hurneness Asperer unokunemba okuphezulu kokuhlola kanye nokuhlakazeka okuncane kwamanani alukhuni. Inani lokuqina elilinganisiwe limele kakhulu ngobulukhuni bangempela lomsebenzi. Ngakho-ke, umhloli we-Brinell Hurneness usetshenziswa kabanzi embonini etholakalayo.
Rocwell Hurdness
Abahloli be-Rocwer Burveness bavame ukusetshenziswa ekuhlolweni kobulukhuni be-cast iron. Kwemisebenzi yokusebenza ngezinhlamvu ezinhle, uma kungekho ndawo eyanele yokuhlolwa kobulukhuni be-Brinell, ukuhlolwa kobulukhuni be-Rocwell nakho kungaqhutshwa. Ukuze uthole i-Iron ye-Pearlitic Malleable Cast, i-Iron Cound yensimbi kanye nokusakathwa kwensimbi, i-HRB noma i-HRC isikali singasetshenziswa. Uma okuqukethwe kungafanele ngokulinganayo, ukufundwa okuningana kufanele kulinganiswe futhi inani elijwayelekile kufanele lithathwe.
Umhloli wobulukhuni basogwini
Ezimweni ngazinye, kokunye kwezinkohliso ezinobukhulu obukhulu, akuvunyelwe ukusika isampula, futhi akuvunyelwe ukuqinisa amanye amabhlogo wokuhlola ukuze kuhlolwe kanzima. Ngalesi sikhathi, ukuhlolwa kanzima kuzobhekana nobunzima. Kuleli cala, indlela ejwayelekile ukuvivinya ubulukhuni ngokuhlolisisa kanzima kanzima Isibonelo, ku-roll standard esetshenziswe kabanzi embonini ye-metallurgical, kuchazwe ukuthi umhloli wobulukhuni wasogwini kufanele asetshenziselwe ukuhlola ubulukhuni.
