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 inotevera: Mushure mekubvisa oxide uye decarburized layer pane specimen surface ne grinder, mufananidzo wakaiswa patafura yebasa yakaita V uye Rockwell kuomarara bvunzo yakaitwa yakananga kunze kwayo. uchishandisa HRS-150S dhijitari kuratidza Rockwell kuomarara tester pakuremerwa :980.7N.
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 hwemuenzaniso. yakataurwa 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 rutsigiro pakati yakatetepa-madziro simbi chubhu, nekuti haigone kuve nechokwadi chekuti indenter axis uye mutoro wekurodha mafambiro uye nepamusoro pepombi yesimbi perpendicular kumusoro, uye yekunze yesimbi pombi uye. ipapo kuchakonzera gaka retsigiro yecylindrical yegap pakati pedenderedzwa pamusoro pepombi yesimbi uye cylindrical yekutsigira nzvimbo, zvinokonzeresa kuti bvunzo mhedzisiro yakaderera.
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.
