Kuvandudzwa Kutsva kweAutomatic Vickers Hardness Tester - Head otomatiki Up & Down Type

Muchina wekuedza kuomarara weVickers unoshandisa dhaimani inodzvanywa pamusoro pemuenzaniso uchishandisa simba rekuyedza. Bvisa simba rekuyedza mushure mekuchengetedza nguva yakatarwa uye kuyera kureba kwedivi redivi, ipapo kukosha kwesimba reVickers (HV) kunoverengerwa zvichienderana nefomura.

Mhedzisiro yekudzvanya musoro pasi

- Kushandisa simba rekuyedza: Maitiro ekudzvanya musoro pasi idanho guru rekutumira simba rekuyedza rakaiswa (rakadai se1kgf, 10kgf, nezvimwewo) pamusoro pechinhu chakaedzwa kuburikidza ne indenter.

- Kugadzira indentation: Kudzvanywa kunoita kuti indentation isiye indentation yakajeka yedhaimani pamusoro pechinhu, uye kuoma kwayo kunoverengerwa nekuyera kureba kwe indentation.

Basa iri rinoshandiswa zvakanyanya mukuyedza kuomarara kwezvinhu zvesimbi, machira matete, machira ekuputira, nezvimwewo, nekuti rine simba rakakura rekuyedza uye gomba diki, iro rakakodzera kuyerwa nemazvo.

Sechishandiso chakajairika cheVickers hardness tester (yakasiyana ne workbench rising type), mabhenefiti e "head pressing down" ndiwo musoro we operation logic uye mechanical structure, ruzivo rwakadai seizvi,

1. Kushanda kuri nyore, tevedzera maitiro emuchina wevanhu

Mukugadzira musoro uchidzvanya pasi, mushandi anogona kuisa sampuro zvakananga pabhenji rebasa rakagadzika, uye kupedzisa kubata nekurodha kwe indenter nemusoro uchidzika pasi, pasina kugadzirisa kukwirira kwebhenji rebasa kakawanda. Pfungwa iyi yekushanda "yepamusoro-pasi" yakakodzera maitiro echinyakare ekushanda, kunyanya kune vatsva, inogona kuderedza matanho anonetesa ekuisa sampuro uye kurongeka, kuderedza zvikanganiso zvekushanda kwevanhu.

2. Kugadzikana kwakasimba kwekutakura, kunyatsoyera kwakakwirira

Chimiro chekudzvanya musoro pasi chinowanzo tora nzira yakasimba yekurodha (senge tsvimbo dzemasikuruu chaiwo uye nzira dzekutungamira). Pakushandisa simba rekuyedza, kumira uye kumhanya kwekurodha kweindenter zviri nyore kudzora, izvo zvinogona kuderedza zvinobudirira kudedera kwemuchina kana kudzima. Kune zvinhu zvakanyatsonaka zvakaita semachira matete, machira, uye zvikamu zvidiki, kugadzikana uku kunogona kudzivirira kushanduka kwekudzika kweindenter kunokonzerwa nekudzika kusina kugadzikana uye kuvandudza zvakanyanya kurongeka kwekuyera.

3. Kuchinjika kwakakura kwemasampuli

Kune mienzaniso yakakura, chimiro chisina kurongeka kana huremu hwakanyanya, dhizaini yemusoro-pasi haidi kuti bhenji rekushandira ritakure mutoro wakawandisa kana zvirambidzo zvekureba (bhenji rekushandira rinogona kugadziriswa), uye rinongoda kuve nechokwadi chekuti sampuro inogona kuiswa pabhenji rekushandira, iro "rinoshivirira" sampuro. Dhizaini yebhenji rekushandira rinokwira inogona kuganhurirwa nekumhanya kwebhenji rekushandira rinotakura mutoro uye rinosimudza, saka zvakaoma kugadzirisa kune sampuro hombe kana dzinorema.

4. Kugona kudzokororwa kwekuyera zviri nani

Nzira yekurodha yakagadzikana uye maitiro ekushanda ari nyore anogona kuderedza kukanganisa kunokonzerwa nekusiyana kwekushanda kwevanhu (senge kuchinjika kwekuenderana kana workbench yasimudzwa). Pakuyera sampuro imwe chete kakawanda, mamiriro ekubatana pakati pe indenter nemasamples anowirirana, kudzokororwa kwedata kuri nani, uye kuvimbika kwemhedzisiro kwakakwira.

Mukupedzisa, muchina wekuedza kuomarara weVickers une mabhenefiti akawanda mukureruka, kugadzikana, uye kuchinjika nekuvandudza mashandiro uye chimiro chemakanika, uye wakakodzera zvakanyanya kuyedzwa kwezvinhu nemazvo, kuyedzwa kwemasampuru emhando dzakasiyana-siyana kana kuyedzwa kwemazinga epamusoro-soro.
