Ungasarudza sei chinhu chinoedza kuomarara kuti uedze masampuli echubhu?

1) Muchina wekuyedza kuomarara weRockwell ungashandiswa here kuyedza kuomarara kwemadziro epombi yesimbi?

Zvinhu zvekuyedza ipombi yesimbi yeSA-213M T22 ine dhayamita yekunze ye16mm uye ukobvu hwemadziro hwe1.65mm. Mhedzisiro yekuyedza kuomarara kweRockwell ndeiyi inotevera: Mushure mekubvisa chiyero cheoxide uye decarburization layer pamusoro pemuenzaniso ne grinder, muenzaniso unoiswa pabenji rebasa rakaita seV, uye HRS-150S digital Rockwell hardness tester inoshandiswa kuyedza zvakananga kuomarara kweRockwell pamusoro payo ne load ye 980.7N. Mushure mekuyedza, zvinogona kuonekwa kuti madziro epombi yesimbi ane deformation diki, uye mhedzisiro ndeyekuti kukosha kwekuomarara kweRockwell kwakayerwa kwakaderera zvakanyanya, zvichikonzera bvunzo isiriyo.

Sekureva kweGB/T 230.1-2018 «Metallic Materials Rockwell Hardness Test Part 1: Test Method», kuomarara kweRockwell i80HRBW uye ukobvu hwesampuro hushoma i1.5mm. Ukobvu hwesampuro Nhamba 1 i1.65mm, ukobvu hwechikamu chakabviswa kabhoni i0.15~0.20mm, uye ukobvu hwesampuro mushure mekubvisa chikamu chakabviswa kabhoni i1.4~1.45mm, iyo iri pedyo neukobvu hushoma hwesampuro hwakatsanangurwa muGB/T 230.1-2018. Munguva yekuyedza, sezvo pasina rutsigiro pakati pesampuro, zvichakonzera kushanduka kudiki (kusingaonekwe nemaziso), saka kukosha kwechokwadi kwesimba reRockwell kwakaderera.

2) Maitiro ekusarudza chinhu chinoedza kuomarara kwepombi dzesimbi:

Mushure mekuyedzwa kwakawanda pamusoro pekuomarara kwepombi dzesimbi, kambani yedu yasvika pamhedziso dzinotevera:

1. Pakuita bvunzo yekuomarara kweRockwell pamusoro kana bvunzo yekuomarara kweRockwell pamusoro pemapaipi esimbi ane madziro matete, kusatsigira kwakakwana kwemadziro epaipi kunokonzera kuchinja kwemuenzaniso uye kutungamira kumhedzisiro yakaderera yebvunzo;

2. Kana rutsigiro rwesimbi rwakaiswa pakati pepombi yesimbi ine madziro matete, mhinduro dzebvunzo dzichava shoma nekuti denderedzwa remusoro wekumanikidzwa uye gwara rekutakura mutoro hazvigone kuve nechokwadi chekuti zvakamira zvakananga pamusoro pepombi yesimbi, uye pane mukaha pakati pepamusoro pepombi yesimbi nerutsigiro rwesimbi rwakaiswa.

3. Nzira yekushandura kuomarara kweVickers kwakayerwa kuita kuomarara kweRockwell mushure mekupinza nekupukuta sampuro yesimbi yakanyatsojeka.

4. Mushure mekubvisa chiyero che oxide uye decarburization layer pamusoro pepombi yesimbi uye kugadzira test plane pamusoro pekunze uye kuisa mukati mayo, Rockwell hardness pamusoro inoshandurwa kuita Rockwell hardness, iyo iri chaiyo.
