40Cr, 40 chromium Rockwell ubulukhuni indlela yokuhlola

Ngemva kokucisha nokushisa, i-chromium inezici ezinhle kakhulu zemishini nokuqina okuhle, okuyenza ivame ukusetshenziswa lapho kwakhiwa izinsimbi eziqinile, ama-bearings, amagiya nama-camshafts. Izakhiwo zemishini nokuhlolwa kokuqina kuyadingeka kakhulu ku-40Cr ecishiwe futhi eqinile.

Ukuhlola ubulukhuni be-40Cr kuvame ukusebenzisa indlela yokuhlola ubulukhuni be-Rockwell kanye nendlela yokuhlola ubulukhuni be-Brinell ukuze kuhlolwe. Ngoba i-Rockwell hardness tester iyashesha futhi isebenziseka kalula, imvamisa ikhethwa amakhasimende. Ezingxenyeni ezincane noma izingxenye ezidinga ukunemba okuphezulu, i-Vickers tester hardness ingasetshenziswa.

Ngokuvamile, ubulukhuni be-Rockwell obungu-40Cr ngemva kokucisha kanye nokushisa kuvame ukudingeka ukuthi bube phakathi kwe-HRC32-36, ukuze ibe namandla aphezulu kanye nokumelana nokukhathala.

Okulandelayo kukhona abahloli bokuqina be-Rockwell abavame ukusetshenziswa njengereferensi:

1. Isibonisi sedijithali esinesisindo esingeziwe sikagesi Isihloli sokuqina sokuqina kwe-Rockwell: okunembile, okuthembekile, okuqinile, nokusebenza kahle kokuhlolwa okuphezulu; isibonisi sedijithali singafunda ngokuqondile inani lobulukhuni be-Rockwell, ukwakheka komshini kuyathuthukiswa, futhi ezinye izikali ze-Rockwell zingafaniswa ngokuzithandela. Isebenzisa ubuchwepheshe bokulayishwa nokulayisha okuzenzakalelayo kukagesi ukuze kuqedwe amaphutha abantu. Isistimu yokuphotha yamukela isakhiwo sokuphotha esingakhubeki ukuze sithuthukise ukunemba kwamandla okuqala okuhlola

2. Isikrini sokuthinta isibonisi sedijithali Umhloli wokuqina we-Rockwell: ukusebenza kwesikrini sokuthinta esingamayintshi ayisishiyagalombili, isikhombimsebenzisi esibonakalayo esilula futhi esisebenziseka kalula; amandla okuhlola ukulayisha nge-elekthronikhi, izinga lokuhluleka eliphansi, ukuhlolwa okunembe kakhudlwana, kungagcina ngokuzimela amasethi edatha angu-500, kucishwe amandla ngaphandle kokulahlekelwa idatha, ngokuhambisana ne-ISO, ASTM E18 namanye amazinga.

3. Umhloli wobulukhuni be-Rockwell ozenzakalelayo ngokugcwele: amandla okuhlola ukulayisha nge-elekthronikhi asetshenziselwa ukuthuthukisa ukunemba kwenani lamandla, ngokuchofoza okukodwa ukuqedela yonke inqubo yokuhlola ubulukhuni, elula futhi ephumelelayo; inkundla yokuhlola enkulu kakhulu, elungele ukutholwa kobunzima bomsebenzi omkhulu; ifakwe induku yokudlala ukushayela ngokushesha i-servo motor ukulungisa indawo yokuhlola; idatha ingadluliselwa kukhompyutha nge-RS232, i-Bluetooth noma i-USB.
