Iyo kodhi yekuomarara kwesimbi ndeye H. Maererano neyakasiyana yekuyedza nzira dzekuyedza, zvinomiririra zvakajairika zvinosanganisira Brinell (HB) (HV), mahombekombe (HS), pakati peHB uye HB uye HB uye HRC vanonyanya kushandiswa. Hb ine huwandu hwakawanda hwekushandisa, uye hrc yakakodzera zvigadzirwa zvine hupfumi hwepamusoro, sekusagadzikana kwekupfura kwekurapa. Musiyano ndewekuti indender yeiyo kuomesa tester yakasiyana. Iyo brinell hardness tester is bhora indender, nepo iyo dombowell hardness tester ndeye diamond indenter.
HV-yakakodzera kune microscope kuongorora. Vickers kuomarara (HV) Dzvanya iyo zvinhu zvine mwero nemutoro wezvishoma pane 120kg uye diamondi Square Canne neVertex ye136 °. Iyo nzvimbo yemukati yezvinhu zvitsva indentation yakakamurwa neyekutakura kukosha, iyo iri vickers kuomesa kukosha (HV). Vickers kuomarara kunoratidzwa seHV (Taura neGB / T4340-1999), uye inoyera zvakanyanya samples.
HL Inotakurika Hardness Tester inokodzera kuyerwa kuyerwa. Inoshandisa iyo yekukanganisa bhora musoro kuti upe nzvimbo yakaoma uye inoburitsa kubhururuka. Iko kuomarara kunoverengerwa neiyo ratio yeiyo Rebound kumhanya kweiyo punch ku 1mm kubva kune sampula mamiriro ekumhanyisa. Iyo formula ndeye: Leeb Hardness HL = 1000】 vb (Rebound Speed) / VA (IMPUCT SEIPE).
Inotakurika Leeb Tester inogona kushandurwa kuita brinell (HB), rockwell (hrc), vickers (hv), mahombekombe (hS) kuomarara mushure mekuyera. Kana kuti ushandise leeb shuni kune zvakananga kuomesa kukosha neBrinell (HB), Rockwell (HRC), Vickers (HV), Shore (HL (HS), Shore (HL).
Hb - kuomarara kweBrinell:
Kuomarara kweBrinell Rockwell kuomarara (hrc) kunowanzo shandiswa kune zvigadzirwa zvine hupfu hwakakwirira, sekuomesa mushure mekurapa kwekushisa, nezvimwe.
Kuomarara kweBrinell (HB) ndeyekuyedza mutoro weimwe saizi. Bhora rakaomeswa simbi kana bhora rebhokisi reimwe dhayamita rakamanikidzwa mukati mevaranda simbi kuti vaongororwe. Mutoro wekuyedza unochengetwa kwenguva yakatarwa, uyezve mutoro wacho unobviswa kuyera dhayamu yeiyo induction pamusoro kuti uongororwe. Iko kuomarara kweBrinell ndiyo quotient yakawanikwa nekukamura mutoro neyechiona nzvimbo yemukati yekunyora. Kazhinji, bhora rakaomeswa simbi weimwe simbi (kazhinji 10mm muDivhisi) rinodzvanywa mune iyo zvinhu zvemukati neine mutoro (kazhinji 3000kg) uye inochengetwa kwenguva yakati rebei. Mushure mekunge mutoro wabviswa, iyo chiyero chemutoro kune iyo induction nzvimbo ndiyo brinell hardness kukosha (HB), uye unit ndeye Kilograph / mm2 (N / MM2).
Rockwell kuomarara kunosarudza kuomarara kweKutenderwa Index kunoenderana nepurasitiki kurongedza kudzika kweIntendi. 0.002 mm inoshandiswa seyakaomarara unit. Kana hb> 450 kana sampuli idiki, iyo brinell kuomesa bvunzo hakugone kushandiswa uye mhouconell hardness chiyero chinoshandiswa pachinzvimbo. Inoshandisa madhaimani coni ine vertex angle ye120 ° kana bhora rezvemusoro neyakagadziriswa pane chimwe chinhu chakaedzwa pasi peimwe mutoro, uye kuomarara kwezvinhu zvakaverengerwa kubva pakudzika kwekudzika. Zvinoenderana nekuomesa kwezvinhu zvekuyedza, zvinoratidzwa muzviyero zvitatu zvakasiyana:
Hra: Kuomarara kwakawanikwa uchishandisa 60kg mutoro weAntimini uye Diamond Cone Indender, iyo inoshandiswa kune zvigadzirwa zvine hutsinye zvakanyanya (senge carmed carbide, nezvimwewo).
HRB: Iko kuomarara kunowanikwa nekushandisa bheji re100kg uye bhora rakaomeswa neyakagadziriswa ye1,58mm, iyo inoshandiswa kune yakaomesesa kuomarara (sekusimbirira simbi, yakakwenya simbi, etc.).
HRC: Iko kuomarara kunowanikwa nekushandisa iyo 150kg mutoro wezana uye diamondi cone indender, iyo inoshandiswa kune zvigadzirwa zvine hutsinye hwakanyanya (seyakaomeswa simbi, nezvimwewo).
Pamusoro pe:
1.RCC zvinoreva kuti Rockwell Kuomarara C SALL.
2.RRC uye HB inoshandiswa zvakanyanya mukugadzirwa.
3.rcrc inoshanda range hrc 20-67, yakaenzana ne hb225-650,
Kana kuomarara kwakakwira kupfuura iyi huwandu, shandisa hardwell hardness chiyero HRA,
Kana kuomarara kuri kuderera pane iyi huwandu, shandisa rockwell hardness b sike hrb,
Iyo yekumusoro muganho yekuomarara kwebhuruu ndeye HB650, iyo isingakwanise kukwirira kupfuura iyi kukosha.
4.Kutuka kweTombowell Hardness Tester C Sces in Diamond Cone neVertex angle ye120 degree. Mutoro wekuyedza huwandu hwakati. Iyo Chinese chiyero ndeye 150 kgf. Iyo Inenter yeBrinell Hardness Tester is a akaomeswa simbi bhora (Hbs) kana bhora remabhiza (hbw). Iyo yekuyedza mutoro unosiyana neyakajaira yebhora, kubva ku3000 kusvika 31.25 kgf.
5.The dombowell hardness induction idiki kwazvo, uye kukosha kwakayerwa kunowanikwa. Izvo zvinodikanwa kuyera mapoinzi akati wandei kuti uwane iyo yepakati kukosha. Izvo zvakakodzera zvigadzirwa zvakapera uye zvidimbu zvakatetepa uye zvinokatyamadzwa sekuyedza kusiri kwekuparadza. Iyo brinell kuomarara kwakakura, kukosha kwakayerwa kwakarurama, hazvina kukodzera kuti zvigadzirwa zvakapetwa uye zvidimbu zvakatetepa, uye kazhinji hauna kuongororwa sekuti kusiri kwekuedza kusiri kwekuparadza.
6. Iko kukosha kwekuomarara kweHockwell kuomarara ndeye nhamba isina zita nhamba isina zvikamu. (Naizvozvo, hazvina kunaka kufonera Rockwell kuomarara seimwe dhigirii
7. Kuoma kweRockwell kunoratidzwa zvakananga pane iyo dial kana digitally inoratidzwa. Zviri nyore kushanda, nekukurumidza uye intuitive, uye yakakodzera kugadzirwa kukuru. Kuomarara kweBrinell kunoda microscope kuyera iyo induction dhaya, uye wozotarisa tafura kana kuverenga, iyo inokweretesa kushanda.
8. Pasi pemamwe mamiriro, HB uye HRC inogona kufambiswa nekutarisa tafura. Iyo yepfungwa yekuverenga fomu inogona kuve yakanyorwa se: 1hrc≈1 / 10HB.
Kuedza kuomarara ndeye nzira yakapusa uye iri nyore bvunzo mukuedzwa kwechimiro. Kuti ushandise kuomesa bvunzo kutsiva mamwe manhamba ekuongorora midziyo, hukama hwakanyanya hwekutendeuka pakati pekureba uye simba rinodiwa mukugadzirwa.
Dzidzira yakaratidza kuti pane hukama hunoenderana hunoenderana pakati pezvakawanda zvekuomesa zvinhu zvezvinhu zvesimbi uye pakati pekuomesa kukosha uye kukosha kwesimba. Nekuti kukosha kwehuremu kwakaitwa nekutongwa kwekutanga kupesana nekupararira kwepurasitiki kuramba, kukwirira kweiyo simba rezvinyorwa, yakakwira kupokana kwepurasitiki, uye yakakwira kukosha kwekuomarara.
