Zonke izingxenye eziphathwe ngokushisa kufanele zihlolwe ubulukhuni ngokuhambisana nezincazelo zobuchwepheshe ezidwetshweni kanye nezidingo zemibhalo yenqubo. Umhloli wobulukhuni kumele alinganiswe ngamabhulokhi ajwayelekile okukhombisa ubulukhuni ngaphambi kokuhlolwa, futhi ukuhlolwa kobulukhuni kungenziwa kuphela ngemva kokudlula ekulinganisweni.
Ngaphambi kokuhlolwa kobulukhuni, indawo yokuhlola yezingxenye kumele ihlanzwe kahle ukuze kususwe ngokuphelele isikali, izendlalelo ezikhishwe i-carburet, ama-burrs kanye nezinye izinto ezingcolisayo. Awekho amamaki acacile amathuluzi omshini azosala endaweni yokuhlola. Izingxenye kufanele zihlolwe ekushiseni kwegumbi njengesimo esijwayelekile. Uma izinga lokushisa lomsebenzi liphakeme kancane kunezinga lokushisa elizungezile, ukuhlolwa ngeke kuqhubeke kuze kube yilapho umsebenzi ungabanjwa ngesandla.
Izindawo zokuhlola ubulukhuni kufanele zihlelwe njengoba kuchaziwe emibhalweni yenqubo. Uma kungekho mibandela ecacile, izindawo zokuhlola kufanele zinqunywe ngokubambisana onjiniyela bezinqubo nabahloli.
Indlela Yokukhetha Isivivinyo Sokuqina Esifanele Sezingxenye Eziphathwe Ukushisa
1. Izihloli zokuqina kweBrinell zisetshenziselwa izingxenye ezijwayelekile ezijwayelekile, ezifakwe emanzini futhi ezicinyiwe nezithambile. Izingcezu zomsebenzi zalolu hlobo zinobunzima obuphansi, ukuguquguquka okuhle kanye nesakhiwo sangaphakathi esifanayo. I-indenter ye-carbide enobubanzi obukhulu yabahloli beBrinell idala indawo ebanzi yokugoba ehlanganisa izakhiwo eziningi ze-metallographic. Ukufundwa kokuqina okulinganiselwe okutholiwe kuzinzile kakhulu futhi kungabonisa ngempela izakhiwo eziphelele zemishini zento.
2. Abahloli bokuqina be-Brinell bohlobo lwesando bangasetshenziswa kuma-workpiece amakhulu angenakufakwa kuma-bench testers, okuvumela ukuhlolwa okusheshayo kwendawo ngaphandle kokusika amasampula.
3.Izivivinyo zokuqina kweRockwell zisetshenziswa ezingxenyeni ezicinyiwe. Lezi zingcezu zokusebenza ezicinyiwe zinezingcezu zobulukhuni obuphezulu kanye nokuqhekeka okuphezulu. I-Rockwell diamond cone indenter ingamelana namandla okuhlolwa aphezulu futhi ilinganise kalula ububanzi bobulukhuni obuphezulu. Ukugoba kwayo okuncane ngeke kulimaze izindawo eziqediwe kahle. Inezivivinyo ezisheshayo kanye nokufundwa okuqondile, ifanele ukuhlolwa ngobuningi kwemikhiqizo eqediwe kufaka phakathi imiphini, isikhunta kanye namagiya. Ifakwe itafula lokusebenza lohlobo lwe-V, ingabamba ngokuqinile izingcezu zomsebenzi zebha eyindilinga.
4.Izihloli zokuqina kwe-Vickers kufanele zisetshenziswe ezingxenyeni ezifakwe i-carburing kanye nezingcezu zokusebenza ezinezendlalelo eziqinile nezincane. Izingcezu zokusebenza ezifakwe i-carburing nezine-nitride zinesendlalelo sobuso esiqinile esincane esine-substrate ethambile ngaphansi. Izihloli ze-Vickers zisekela amandla amancane okuhlola futhi zikhiqiza ukugoba okungajulile kakhulu okusebenza kuphela endaweni eqinile ngaphandle kokungena ngaphakathi kwe-substrate. Lokhu kuvumela ukulinganiswa okunembile kokuqina kobuso bangempela.
Lokhu okungenhla kuyisiqondiso esijwayelekile sokukhetha umhloli wobulukhuni. Izimo zokuhlola zangempela ziyinkimbinkimbi, futhi ukukhethwa kwemishini kuthintwa ubukhulu bezinto zokusebenza, ukujiya kwezingqimba eziqinile, kanye nesimo somshini wokugaya. Ukukhetha kokugcina kuzonqunywa ngokusekelwe esimweni sangempela sezinto zokusebenza. Uma uhlangabezana nanoma yiziphi izinkinga ekukhetheni imodeli, zizwe ukhululekile ukuxhumana nathi.Laizhou LaihuaSihlinzeka ngezixazululo zochwepheshe zokuhlola ubulukhuni ezenziwe ngokwezifiso zomuntu ngamunye.
