Indlela yokuhlola ubulukhuni be-Rockwell engu-40Cr, engu-40 chromium

Ngemva kokucima nokulungisa, i-chromium inezakhiwo ezinhle kakhulu zomshini kanye nokuqina okuhle, okwenza ivame ukusetshenziswa ekwenziweni kwezibambo ezinamandla aphezulu, amabheringi, amagiya, kanye nama-camshaft. Izakhiwo zomshini kanye nokuhlolwa kokuqina kuyadingeka kakhulu kuma-40Cr acinyiwe futhi aqinisiwe.

Ukuhlolwa kobulukhuni okungu-40Cr kuvame ukusebenzisa indlela yokuhlola ubulukhuni beRockwell kanye nendlela yokuhlola ubulukhuni beBrinell ukuze kuhlolwe. Ngenxa yokuthi isihloli sobulukhuni beRockwell siyashesha futhi silula ukusisebenzisa, ngokuvamile sithandwa amakhasimende. Ezingxenyeni ezincane noma izingxenye ezidinga ukunemba okuphezulu, isihloli sobulukhuni beVickers singasetshenziswa futhi.

Ngokuvamile, ubulukhuni beRockwell obungu-40Cr ngemva kokucima nokushisa ngokuvamile buyadingeka ukuthi bube phakathi kwe-HRC32-36, ukuze bube namandla aphezulu kanye nokumelana nokukhathala.

Okulandelayo yizihloli eziningana zokuqina kweRockwell ezivame ukusetshenziswa njengereferensi:

1. Isibonisi sedijithali sikagesi esengezwe isisindo Umhloli wobulukhuni beRockwell: onembile, othembekile, ohlala isikhathi eside, futhi osebenza kahle kakhulu ekuhlolweni; isibonisi sedijithali singafunda ngqo inani lobulukhuni beRockwell, isakhiwo semishini silungiselelwe kahle, kanti ezinye izikali zeRockwell zingalinganiswa ngokuzikhethela. Sisebenzisa ubuchwepheshe bokulayisha nokulayisha ngokuzenzakalelayo kagesi ukuze kuqedwe amaphutha abantu. Uhlelo lwe-spindle lusebenzisa isakhiwo se-spindle esingenasiphazamiso ukuze kuthuthukiswe ukunemba kwamandla okuqala okuhlola

2. Isibonisi sedijithali sesikrini sokuthinta I-Rockwell hardness tester: ukusebenza kwesikrini sokuthinta esingamasentimitha ayisishiyagalombili, isikhombikubona esilula nesilula ukusisebenzisa; amandla okuhlola ukulayisha ngogesi, izinga lokwehluleka eliphansi, ukuhlolwa okunembe kakhudlwana, kungagcina ngokuzimela amasethi edatha angu-500, kucime ngaphandle kokulahleka kwedatha, ngokuhambisana ne-ISO, i-ASTM E18 nezinye izindinganiso.

3. Isihloli sokuqina kwe-Rockwell esizenzakalelayo ngokuphelele: amandla okuhlola ukulayisha kagesi asetshenziselwa ukuthuthukisa ukunemba kwenani lamandla, ngokuchofoza kanye ukuqedela yonke inqubo yokuhlola ubulukhuni, kulula futhi kuyasebenza; ipulatifomu yokuhlola enkulu kakhulu, efaneleka kakhulu ekutholakaleni kobulukhuni bomsebenzi omkhulu; ifakwe induku yokudlala yokushayela ngokushesha injini ye-servo ukulungisa isikhala sokuhlola; idatha ingadluliselwa kwikhompyutha nge-RS232, i-Bluetooth noma i-USB.
