I-Leeb Hardness Tester
Njengamanje, i-Leeb hardness tester isetshenziswa kakhulu ekuhlolweni kokuqina kokulingwa.Umhloli wokuqina we-Leeb wamukela isimiso sokuhlola ubulukhuni obushintshashintshayo futhi usebenzisa ubuchwepheshe bekhompiyutha ukuze abone ubulukhuni be-miniaturization kanye ne-electronicization yesihloli sokuqina.Kulula futhi kulula ukuyisebenzisa, ukufunda kunembile, futhi imiphumela yokuhlolwa ingaguqulwa kalula ibe amanani wobulukhuni be-Brinell, ngakho-ke yamukelwa kabanzi.
Ama-casting amaningi angama-workpieces aphakathi nendawo kuya kokukhulu, amanye anesisindo esingamathani ambalwa, futhi awakwazi ukuhlolwa kusihloli sokuqina sokuqina kwebhentshi.Ukuhlolwa kokuqina okunembile kokulingisa ikakhulukazi kusebenzisa izinti zokuhlola ezihlukene noma amabhulokhi okuhlola anamathiselwe ekulingisweni.Kodwa-ke, akukho bha yokuhlola noma ibhulokhi yokuhlola engakwazi ukufaka esikhundleni ngokuphelele isiqeshana somsebenzi uqobo.Ngisho noma kuyisithando somlilo esifanayo sensimbi encibilikisiwe, inqubo yokuphonsa kanye nezimo zokwelashwa kokushisa ziyafana.Ngenxa yomehluko omkhulu ngobukhulu, izinga lokushisa, ikakhulukazi izinga lokupholisa, lizohluka.Kunzima ukwenza laba bobabili babe nobulukhuni obufana ncamashi.Ngenxa yalesi sizathu, amakhasimende amaningi anendaba kakhulu futhi akholelwa ebukhuni bomsebenzi ngokwawo.Lokhu kudinga isihloli sokuqina sokuqina esiphathekayo ukuze sihlole ubulukhuni bokulingisa.Umhloli wokuqina we-Leeb uyayixazulula le nkinga, kodwa kuyadingeka ukuthi unake isiphetho esingaphezulu se-workpiece ngesikhathi kusetshenziswa isihloli sokuqina sika-Leeb.Umhloli wokuqina we-Leeb unezidingo zokuqina kwendawo yokusebenza.
I-Brinell Hardness Tester
I-Brinell hardness tester kufanele isetshenziselwe ukuhlola ubulukhuni bokubunjwa.Ukuze kufakwe insimbi empunga enezinhlamvu ezimahhadlahhadla, izimo zokuhlola zamandla angu-3000kg nebhola elingu-10mm kufanele zisetshenziswe kakhulu ngangokunokwenzeka.Uma usayizi wokulingisa umncane, i-Rockwell hardness test nayo ingasetshenziswa.
I-iron castings ngokuvamile inokwakheka okungalingani, okusanhlamvu okukhulu, futhi iqukethe ikhabhoni eningi, i-silicon nokunye ukungcola kunensimbi, futhi ukuqina kuzohluka ezindaweni ezincane ezahlukene noma ezindaweni ezahlukene.I-indenter yesihloli sokuqina sokuqina kwe-Brinell inosayizi omkhulu kanye nendawo enkulu yokuhlehlisa, futhi ingakala inani elimaphakathi lobulukhuni bezinto phakathi kwebanga elithile.Ngakho-ke, umhloli wokuqina we-Brinell unokunemba okuphezulu kokuhlolwa kanye nokuhlakazwa okuncane kwamanani okuqina.Inani lokuqina elilinganisiwe limelela kakhulu ubulukhuni bangempela bomsebenzi wokusebenza.Ngakho-ke, i-Brinell tester hardness isetshenziswa kabanzi embonini yokusungula.
Ukuqina kwe-Rockwell
Izihloli zokuqina kwe-Rockwell nazo zivame ukusetshenziselwa ukuhlola ubulukhuni bensimbi ekhonjiwe.Ngezicucu zokusebenza ezinezinhlamvu ezinhle, uma ingekho indawo eyanele yokuhlola ubulukhuni be-Brinell, ukuhlolwa kokuqina kwe-Rockwell nakho kungenziwa.Okwensimbi esansimbi ephathekayo ethambile, insimbi ephonsiwe ebandayo kanye nezinsimbi zensimbi, i-HRB noma isikali se-HRC singasetshenziswa.Uma impahla ingekho Ngokulinganayo, ukufundwa okuningana kufanele kukalwe futhi inani elimaphakathi kufanele lithathwe.
I-Shore Hardness Tester
Ezimweni ezingazodwana, kokunye ukulingisa okunobumo obukhulu, akuvunyelwe ukusika isampula, futhi akuvunyelwe ukuphonsa amabhulokhi okuhlola engeziwe ukuze kuhlolwe ubulukhuni.Ngalesi sikhathi, ukuhlolwa kokuqina kuzohlangabezana nobunzima.Kulesi simo, indlela evamile ukuhlola ubulukhuni ngesihloli sokuqina sokuqina kwe-Shore endaweni ebushelelezi ngemva kokuqedwa kokusakazwa.Isibonelo, kuhlelo olujwayelekile olusetshenziswa kakhulu embonini yensimbi, kubalulwe ukuthi isihloli sokuqina sase-Shore kufanele sisetshenziselwe ukuhlola ubulukhuni.
