1) Rockwell hardness tester inogona kushandiswa kuyedza kuoma kwesimbi pombi madziro?
Iyo yekuyedza zvinhu ndeye SA-213M T22 simbi pombi ine dhayamita yekunze ye16mm uye kukora kwemadziro 1.65mm. Mhedzisiro yemhedzisiro yeRockwell hardness tester ndeiyi: Mushure mekubvisa oxide uye decarburized layer pamusoro pemuenzaniso wepamusoro neguyo, mufananidzo wacho wakaiswa patafura yebasa yakaita V uye Rockwell kuomarara bvunzo yakaitwa yakananga kunze kwayo, uchishandisa HRS-150S digital display Rockwell hardness tester pakuremerwa :980.
Mushure mekuedzwa, zvinogona kuonekwa kuti pombi yesimbi pamadziro ine zvishoma deformation, uye mugumisiro ndewokuti: kukosha kwakaderera kuyerwa kweRockwell kuoma kunoita kuti bvunzo isashande.
Zvinoenderana neGB/T 230.1-2018 "Rockwell Hardness bvunzo yezvinhu zvesimbi Chikamu 1: Nzira dzekuyedza", iyo Rockwell kuomarara ndeye 80HRBW uye hushoma hukobvu hwemuenzaniso i1.5mm. Ukobvu hwesample No.1 i1.65mm, ukobvu hweiyo decarburized layer i0.15 ~ 0.20mm, uye ukobvu hwesample mushure mekubvisa decarburized layer ndeye 1.4 ~ 1.45mm, iri padyo nehupamhi hudiki hwesample inotsanangurwa muGB/T 230.1-2018.
Munguva yekuyedzwa, nekuda kwenzvimbo yemuenzaniso haina kutsigirwa, inokonzeresa (pamwe isingaonekwe neziso rakashama) deformation, saka iyo Rockwell kuomarara kuyerwa kukosha kuri kuderera.
2) Maitiro ekusarudza epamusoroRockwellhardness tester yekuyedza mapaipi esimbi:
Kambani yedu yakamboedza zvakare kuomarara kwesimbi pombi uye yakasvika kune inotevera mhedziso:
Superficial Rockwell kuomarara bvunzo kana Rockwell kuomarara bvunzo pamusoro pepombi yesimbi yakatetepa. Kusakwana kwerutsigiro rwemadziro kunokonzeresa deformation ye specimen uye kukonzeresa yakaderera bvunzo mhinduro;
Kana isa cylindrical tsigiro pakati pehutete-madziro simbi chubhu, nekuti haigone kuve nechokwadi chekuti indenter axis uye mutoro wekurodha mafambiro uye nepamusoro pepombi yesimbi perpendicular kumusoro, uye kunze kwepombi yesimbi uye ipapo pachaita gaka retsigiro yecylindrical yegapu pakati peiyo denderedzwa pamusoro pepombi yesimbi uye iyo cylin inokonzeresa mhedzisiro, inokonzeresa kuderera kwe cylin.
Shandura Vickers kuomarara kuyedzwa kuita Rockwell kuomarara kuyedza mushure mekupukuta simbi pombi sampling inset, inowana iyo chaiyo Rockwell kuomarara kukosha.
2. Mushure mekubvisa oxide uye decarburization layer pamusoro pepombi yesimbi uye machining ndege yekuyedza pamusoro pekunze uye kuipinza, Kukosha kwakanyatso kuenzaniswa neSuperficial Rockwell kuomarara tester neRockwell kuomarara tester.
