1) Ko Rockwell hardness tester inogona kushandiswa here kuyedza kuomarara kwemadziro epombi yesimbi?
Chinhu chekuedza ipombi yesimbi yeSA-213M T22 ine dhayamita yekunze ye16mm uye ukobvu hwemadziro hwe1.65mm. Mhedzisiro yekuedza kweRockwell hardness tester ndeiyi inotevera: Mushure mekubvisa oxide ne decarburised layer pamusoro pemuenzaniso ne grinder, sampuli yakaiswa patafura yebasa yakaita seV uye Rockwell hardness test yakaitwa zvakananga pamusoro wayo wekunze, uchishandisa HRS-150S digital display Rockwell hardness tester pa load :980.7N.
Mushure mebvunzo, zvinoonekwa kuti pombi yesimbi iri pamadziro ine shanduko diki, uye mhedzisiro yacho ndeyekuti: kukosha kwakaderera kwakayerwa kwekuomarara kweRockwell kunoita kuti bvunzo isashande.
Zvinoenderana neGB/T 230.1-2018 «Kuedza kweRockwell Hardness kwezvinhu zvesimbi Chikamu 1: Nzira dzekuedza », kuomarara kweRockwell i80HRBW uye ukobvu hushoma hwemuenzaniso i1.5mm. Ukobvu hwemuenzaniso Nhamba 1 i1.65mm, ukobvu hwechikamu chakabviswa kabhoni i0.15~0.20mm, uye ukobvu hwemuenzaniso mushure mekubvisa chikamu chakabviswa kabhoni i1.4~1.45mm, iyo iri pedyo neukobvu hushoma hwemuenzaniso hwakatsanangurwa muGB/T 230.1-2018.
Munguva yebvunzo, nekuda kwekuti nzvimbo yemuenzaniso haina kutsigirwa, zvichaita kuti pave nekushanduka kudiki (zvichida kusingaonekwe nemaziso), saka kukosha kwekuomarara kweRockwell kwakaderera.
2) Maitiro ekusarudza zviri pamusoroRockwellmuyedzi wekuomarara wekuyedza mapaipi esimbi：
Kambani yedu yakaedza kakawanda kuoma kwepombi yesimbi uye yakasvika pamhedziso dzinotevera：
Kuedza kuomarara kweRockwell kana kuti kuedza kuomarara kweRockwell pamusoro pepombi yesimbi ine madziro matete. Kusatsigira madziro kwakakwana kunokonzera kuchinja kwemuenzaniso uye kunokonzera mhedzisiro shoma yekuedza;
Kana ukaisa rutsigiro rwe cylindrical pakati pechubhu yesimbi yakatetepa, nekuti haigone kuve nechokwadi chekuti indenter axis uye mutoro wekutakura mutoro uye pamusoro pechubhu yesimbi zvakatarisa pamusoro, uye pamusoro pechubhu yesimbi uye ipapo zvichakonzera mukana wekutsigira cylindrical wemukana uri pakati pepamusoro pechubhu yesimbi nepamusoro pechubhu yekutsigira cylindrical, zvichaitawo kuti mhedzisiro yebvunzo ive yakaderera.
Shandura kuyedzwa kwekuomarara kweVickers kuita kuyedzwa kwekuomarara kweRockwell mushure mekupukuta pombi yesimbi, uchawana kukosha kwekuomarara kweRockwell kwakarurama.
2. Mushure mekubvisa oxide ne decarburization layer pamusoro pepombi yesimbi uye kugadzira test plane pamusoro pekunze uye kuisa mukati mayo, Kukosha kwacho kwakanyatsojeka kana tichienzanisa neSuperficial Rockwell hardness tester neRockwell hardness tester.
