1 Kugadzirira kusati kwaedzwa
1) The hardness tester uye indenter inoshandiswa paVickers kuomarara bvunzo inofanirwa kuenderana nezvinodiwa zveGB/T4340.2;
2) Tembiricha yekamuri inofanirwa kudzorwa mukati meiyo 10 ~ 35 ℃. Kune bvunzo dzine yakakwirira chaiyo zvinodiwa, inofanirwa kudzorwa pa (23±5) ℃.
2 Samples
1) Muenzaniso wepamusoro unofanirwa kuve wakatsetseka uye wakatsetseka. Zvinokurudzirwa kuti sampuli yepamusoro roughness inofanira kusangana nezvinodiwa: Maximum value of surface roughness parameter: Vickers hardness sample 0.4 (Ra)/μm; diki mutoro Vickers kuoma sampuli 0.2 (Ra)/μm; micro Vickers kuomarara sampuli 0.1 (Ra)/μm
2) Kune diki mutoro Vickers uye micro Vickers samples, zvinokurudzirwa kusarudza kwakakodzera polishing uye electrolytic polishing yekurapwa kwepamusoro zvinoenderana nerudzi rwezvinhu.
3) Ukobvu hwesample kana test layer inofanira kunge iri 1.5 times the diagonal kureba kweiyo indentation.
4) Paunenge uchishandisa mutoro mudiki uye micro Vickers yekuyedza, kana sampuli iri diki kwazvo kana isina kurongeka, sampuro inofanirwa kuiswa kana kusungirirwa neyakagadziriswa isati yaedzwa.
3Test method
1) Kusarudzwa kwesimba rekuedza: Zvinoenderana nekuoma, ukobvu, ukuru, nezvimwe zvemuenzaniso, simba rekuyedza rinoratidzwa muTafura 4-10 rinofanira kusarudzirwa bvunzo. .
2) Kuedza simba rekushandisa nguva: Nguva kubva pakatanga kushandiswa kwechisimba kusvika pakupedzwa kweiyo yakazara test force application inofanira kunge iri mukati me2 ~ 10 s. Kune diki mutoro Vickers uye micro Vickers kuomarara bvunzo, iyo indenter inodzika kumhanya haifanirwe kudarika 0.2 mm/s. Kuedza simba kubata nguva ndeye 10 ~ 15 s. Kune kunyanya zvinyoro zvinyoro, nguva yekubata inogona kuwedzerwa, asi kukanganisa kunofanirwa kunge kuri mukati me2.
3) Kureba kubva pakati peiyo indentation kusvika kumucheto wemuenzaniso: Simbi, mhangura uye mhangura alloys inofanira kunge inenge 2.5 nguva yakareba diagonal ye indentation; simbi dzakareruka, lead, tin uye alloys avo anofanirwa kunge ari kanenge katatu kureba kwediagonal ye indentation. Nharaunda pakati pepakati pezviviri zviri pedo indentations: yesimbi, mhangura uye mhangura alloys, inofanira kuva kanenge katatu kureba kwemutsara we diagonal wechiratidzo chekumira; kune simbi dzakareruka, lead, tin uye alloys adzo, zvinofanirwa kunge zvakapetwa ka6 kureba kweiyo diagonal mutsara weiyo indentation.
4) Edza iyo arithmetic inoreva kureba kwema diagonals maviri eiyo indentation, uye tsvaga iyo Vickers kuomarara kukosha zvinoenderana netafura, kana kuverenga kukosha kwekuoma zvinoenderana neformula.
Kusiyana kwehurefu hwema diagonal maviri e indentation mundege haifaniri kudarika 5% yevhareji inokosha ye diagonals. Kana ikadarika, inofanirwa kucherechedzwa mumushumo webvunzo.
5) Paunenge uchiyedza pane yakakomberedzwa pamusoro sampuli, mhedzisiro inofanirwa kugadziriswa zvinoenderana netafura.
6) Kazhinji, zvinokurudzirwa kuzivisa hurema hwekuyedza kukosha kwemapoinzi matatu kune yega yega sampu.
4 Vickers hardness tester classification
Kune mhando mbiri dzeanowanzo shandiswa Vickers kuomarara testers. Iyi inotevera sumo kune inowanzoshandiswa Vickers hardness tester kushandiswa:
1. Eyepiece kuyerwa mhando;
2. Software kuyerwa mhando
Classification 1: Eyepiece yekuyera mhando Zvimiro: Shandisa eyepiece kuyera. Kushandiswa: Muchina unoita (diamond ◆) indentation, uye kureba kwediagonal kwedhaimondi kunopimwa nemboni yeziso kuti uwane kukosha kwekuoma.
Classification 2: Software kuyerwa mhando: Zvimiro: Shandisa kuomarara software kuyera; nyore uye nyore pameso; inogona kuyera kuoma, kureba, chengetedza mapikicha ekunyora, mishumo yenyaya, nezvimwewo. Kushandisa: Muchina unoita (diamond ◆) indentation, uye kamera ye digital inounganidza indentation pakombiyuta, uye kukosha kwekuoma kunoyerwa pakombiyuta.
5Software classification: 4 shanduro dzekutanga, otomatiki turret control vhezheni, semi-otomatiki vhezheni, uye yakazara otomatiki vhezheni.
1. Basic version
Inogona kuyera kuomarara, kureba, kuchengetedza mapikicha emukati, nyaya dzenyaya, nezvimwe;
2.Kudzora otomatiki turret shanduro software inogona kudzora kuomarara tester turret, senge, chinangwa lens, indenter, kurodha, nezvimwewo;
3.Semi-automatic version nemagetsi XY test table, 2D platform control box; Pamusoro peiyo otomatiki turret vhezheni basa, software inogona zvakare kuseta nzvimbo uye mapoinzi, otomatiki dotting, otomatiki kuyerwa, nezvimwe;
4.Fully automatic version nemagetsi XY test table, 3D platform control box, Z-axis focus; Pamusoro peiyo semi-otomatiki shanduro basa, software inewo Z-axis yekutarisa basa;
6Nzira yekusarudza yakakodzera Vickers hardness tester
Mutengo weVickers hardness tester uchasiyana zvichienderana nekugadzirisa uye basa.
1. Kana iwe uchida kusarudza yakachipa, saka unogona kusarudza:
Equipment ine diki LCD skrini uye bhuku diagonal kupinza kuburikidza nemeso;
2. Kana iwe uchida kusarudza mudziyo usingadhuri, saka unogona kusarudza:
Equipment ine hombe yeLCD skrini, yeziso ine encoder yedhijitari, uye yakavakirwa-mukati printa;
3. Kana uchida imwe upscale mudziyo, ipapo unogona kusarudza:
Zvishandiso zvine touch screen, yakavharwa-loop sensor, eyepiece ine printer (kana USB flash drive), worm gear yekusimudza screw, uye digital encoder;
4. Kana iwe uchifunga kuti zvinonetesa kuyera nemboni yeziso, saka unogona kusarudza:
Yakashongedzerwa neCCD kuomarara kwechifananidzo chekugadzirisa system, kuyera pakombuta usingatarise ziso, iri nyore, intuitive, uye nekukurumidza. Iwe unogona zvakare kugadzira mishumo uye kuchengetedza indentation mifananidzo, nezvimwe.
5. Kana iwe uchida kushanda kuri nyore uye yakakwira otomatiki, saka unogona kusarudza:
Otomatiki Vickers kuomarara tester uye zvizere otomatiki Vickers kuomarara tester
Zvimiro: isa nzvimbo uye nhamba yemapoinzi, otomatiki uye inoenderera dot, uye otomatiki kuyera.
