1) Rockwell hardness tester inogona kushandiswa kuyedza kuomarara kwesimbi pombi madziro?
Iyo yekuyedza zvinhu ndeye SA-213M T22 simbi pombi ine dhayamita yekunze ye16mm uye kukora kwemadziro kwe1.65mm. Mhedzisiro yebvunzo yeRockwell kuomarara bvunzo ndeiyi: Mushure mekubvisa iyo oxide sikeri uye decarburization layer pamusoro peiyo sampuli neguyo, sampu inoiswa pane yakaita V-yakaita workbench, uye HRS-150S digital Rockwell kuomarara tester inoshandiswa kuyedza zvakananga Rockwell kuomarara kwekunze kwayo ine mutoro we980.7N. Mushure mekuyedzwa, zvinogona kuoneka kuti simbi pombi madziro ine zvishoma deformation, uye mhedzisiro ndeyekuti iyo Rockwell kuomarara kukosha kwakayerwa kwakadzikira, zvichikonzera bvunzo isingaite.
Zvinoenderana neGB/T 230.1-2018 «Metallic Materials Rockwell Hardness Test Part 1: Test Method», iyo Rockwell kuomarara ndeye 80HRBW uye mashoma emuenzaniso ukobvu i1.5mm. Ukobvu hwemuenzaniso Nha. 1 ndeye 1.65mm, hupamhi hweiyo decarburized layer ndeye 0.15 ~ 0.20mm, uye hupamhi hwemuenzaniso mushure mekubvisa decarburized layer ndeye 1.4 ~ 1.45mm, iyo iri pedyo nehupamhi hushoma hwemuenzaniso unotsanangurwa muGB / T 230.1-2018. Munguva yekuyedzwa, sezvo pasina tsigiro pakati pemuenzaniso, zvinokonzeresa kuderera (izvo zvingave zvisingaonekwe neziso rakashama), saka iyo chaiyo Rockwell kuoma kukosha kwakaderera.
2) Maitiro ekusarudza iyo yekuomarara tester yemapombi esimbi:
Mushure mekuedzwa kwakawanda pamusoro pekuomarara kwepombi dzesimbi, kambani yedu yakasvika kune zvinotevera mhedziso:
1. Paunenge uchiitisa Rockwell kuomarara bvunzo kana Rockwell kuomarara bvunzo pamusoro pemapaipi esimbi akatetepa, kusakwana kwerutsigiro rwepombi madziro kunokonzeresa deformation uye kutungamirira kune yakaderera bvunzo mhinduro;
2. Kana tsigiro ye cylindrical yakawedzerwa pakati pepombi yesimbi yakaonda-yakakomberedzwa, mhinduro dzekuedza dzichava dzakaderera nokuti axis yemusoro wekumanikidzika uye kutungamira kwekuremerwa kwekutakura hakugone kuvimbiswa kuti ive perpendicular pamusoro pepombi yesimbi, uye pane mukaha pakati pekunze kwepombi yesimbi uye yakagadzirirwa cylindrical support.
3. Nzira yekushandura yakayerwa Vickers kuoma kuti Rockwell kuoma pashure inlaying uye polishing simbi pombi muenzaniso iri chaizvo.
4. Mushure mokubvisa oxide scale uye decarburization layer pamusoro pepombi yesimbi uye kugadzira ndege yekuedza pamusoro pekunze uye kuiisa mukati, iyo Rockwell kuoma kwepamusoro inoshandurwa kuva Rockwell kuoma, iyo inenge yakarurama.
