Indlela yokuhlola ubunzima be-Vickers Hardness kanye nokuphepha

1 Ukulungiselela ngaphambi kokuhlolwa

1) Umhloli wobulukhuni kanye ne-indenter esetshenziselwa ukuhlolwa kanzima kwe-Vickers Hardness kufanele ahambisane nezinhlinzeko ze-GB / T4340.2;

2) Ukushisa kwekamelo kufanele kulawulwa phakathi kwebanga le-10 ~ 35 ℃. Ukuhlolwa ngezidingo eziphakeme zokunemba, kufanele kulawulwe ku- (23 ± 5) ℃.

2 amasampula

1) indawo eyisampula kufanele ibe isicaba futhi ibushelelezi. Kunconywe ukuthi ubulukhuni besampula buhlangabezana nezidingo: inani eliphakeme lepharamitha yokuvuthwa komhlaba: ama-vickers hardness isampula u-0.4 (ra) Umthwalo omncane we-Healvers Hardness Hardness Isampula 0.2 (RA) / μm; I-Micro Vickers Hardness Isampula 0.1 (RA) / μm

2) Kwama-vickers amancane omthwalo kanye namasampula ama-hickers amancane, kunconywa ukukhetha ukucwaswa okufanele kanye ne-electrolytic kokwelashwa komhlaba ngokwezinto ezibonakalayo.

3) Ubukhulu besampula noma i-test ungqimba kufanele okungenani ube izikhathi eziyi-1.5 ubude be-inductonal

4) Uma usebenzisa umthwalo omncane nama-vickers amancane wokuhlola, uma isampula lincane kakhulu noma lingajwayelekile, isampula kufanele ifakwe noma ihlanganiswe nokuhlanganiswa okukhethekile ngaphambi kokuhlolwa.

3Indlela yokuhlola

1) Ukukhethwa kwamandla wokuhlola: Ngokubheka ubulukhuni, ubukhulu, ubukhulu, njll. Kusampula, amandla okuhlola aboniswe kuThebula 4-10 kufanele akhethwe ukuhlolwa. .

2) Isikhathi sesicelo sokuhlola Kuma-vickers amancane omthwalo kanye nokuhlolwa kwe-hicker Hardness Isikhathi sokuhlola esiphethe isikhathi singu-10 ~ 15 s. Ngezinto zokwakha ezithambile ikakhulukazi, isikhathi sokubamba singanwetshwa, kepha iphutha kufanele libe ngaphakathi kwe-2.

3) ibanga ukusuka enkabeni ye-induction emaphethelweni wesampula: insimbi, ithusi kanye ne-copper alloys kufanele okungenani ibe izikhathi eziyi-2,5 ubude be-induction; Izinsimbi ezikhanyayo, ukuhola, i-tin kanye ne-alloys yabo kufanele okungenani ibe izikhathi ezi-3 ubude be-induction. Ibanga phakathi kwezikhungo ezimbili eziseduze: Ngensimbi, ithusi kanye ne-copper alloys, kufanele okungenani ibe izikhathi ezi-3 ubude bomugqa we-diagonal wophawu lokumisa; Ukuze uthole izinsimbi ezikhanyayo, ukuhola, i-tin kanye ne-alloys yazo, kufanele okungenani kube izikhathi ezi-6 ubude bomugqa we-diagonal we-induction

4) ukukala okushiwo ama-arithmetic ngobude bezinto ezimbili ze-indentation, bese uthola ukuthi kulusizo lwabaviki ngokusho kwetafula, noma ukubala inani lobulukhuni ngokuya ngefomula.

Umehluko ngobude bezinto ezimbili ze-diagonals of the induction endizeni akufanele wedlule i-5% yenani eliphakathi le-diagonals. Uma idlula, kufanele kuqashelwe embikweni wokuhlola.

5) Uma uvivinya isampula engaphezulu engasontekile, imiphumela kufanele ilungiswe ngokusho kwetafula.

6) Ngokuvamile, kunconywa ukubika amanani wokuhlola kanzima wamaphuzu amathathu ekhasini ngalinye.

Izigaba ezi-4 zokuhlobisa izinkambiso

Kunezinhlobo ezi-2 zabahloli bukaHardness Hurners ezisetshenziswa kakhulu. Okulandelayo ukwethulwa kokusetshenziswa okuvame ukusetshenziswa ama-vickers Hardness Hurner Invesser:

1.

2. Uhlobo lokulinganisa isoftware

Ukuhlukaniswa 1: Izici zohlobo lwe-Eepiepe Izici: Sebenzisa i-Elepiece ukukala. Ukusetshenziswa: Umshini wenza i- (Diamond ◆), futhi ubude be-diagonal yedayimane bukalwa nge-eye

Ukuhlukaniswa 2: Uhlobo lokulinganisa isoftware: Izici: Sebenzisa isoftware yokuqina ukuze ulinganise; elula futhi elula emehlweni; Ungalinganisa ubulukhuni, ubude, gcina imibiko yokuqalisa, njll. Ukusetshenziswa: Umshini wenza (umshini wedayimane ◆) uqoqa i-induction ekhompyutheni.

Okuthengwa edoloUkuhlukaniswa kwesoftware: Izinguqulo ezi-4 eziyisisekelo, inguqulo ye-othomathikhi yokulawula yeTurret, inguqulo ye-automatic, nenguqulo ezenzakalelayo ephelele.

1. Inguqulo eyisisekelo

Ingalinganisa ubunzima, ubude, gcina izithombe zokufundisa, imibiko yokhipha, njll;

Isoftware ye-Automatic Turret Turret i-Turret ingalawula i-turner tester Turret, njenge, i-lens yenhloso, i-indenter, ukulayisha, njll;
3.Semi-Automatic version enetafula lokuhlola likagesi le-XY, ibhokisi le-2D yesikhulumi sokulawula; Ngaphezu komsebenzi we-othomathikhi we-turret version, isoftware nayo ingasetha izikhala namaphoyinti, amachashazi athomathikhi, ukulinganisa okuzenzakalelayo, njll;
Inguqulo ezenzakalelayo e-automatic enetafula lokuhlola le-Electric XY, ibhokisi lokulawula lokulawula i-3D, ukugxila kwe-Z-axis; Ngaphezu komsebenzi wenguqulo ye-semi-othomathikhi, isoftware nayo inomsebenzi wokugxila we-Z-axis;

6Ungayikhetha kanjani umhloli we-hardness we-vickers ofanele

Intengo yabahloli bendiza be-Vickers Hardness izohluka ngokuya ngokucushwa kanye nokusebenza.

1. Uma ufuna ukukhetha okushibhile, khona-ke ungakhetha:

Okokusebenza ngesikrini esincane se-LCD nokufakwa kwe-diagonal kwe-diagonal nge-eyeesiece;

2. Uma ufuna ukukhetha idivaysi esebenzayo, ungakhetha:

Okokusebenza ngesikrini esikhulu se-LCD, i-eyeesiepe ene-encoder yedijithali, nephrinta eyakhelwe ngaphakathi;

3. Uma ufuna idivaysi ephezulu, ungakhetha:

Okokusebenza ngesikrini sokuthinta, inzwa evaliwe ye-loop, i-eepiede ngephrinta (noma i-USB flash drive), i-Worm Gear Rive ephakamisa isikulufa, ne-Encoder yedijithali;

4. Uma ucabanga ukuthi kuyakhathaza ukukala nge-eyeece, khona-ke ungakhetha:

Ifakwe uhlelo lokucubungula izithombe ze-CCD CCD, ukukala kwikhompyutha ngaphandle kokubheka i-eyeethiede, elula, enembile, futhi esheshayo. Ungakha nemibiko bese ugcine izithombe zokufundisa, njll.

5. Uma ufuna ukusebenza okulula kanye ne-automation ephezulu, khona-ke ungakhetha:

I-othomathikhi ye-vickers hardness Hurneness kanye ne-automal automal hardness testness

Izici: Setha izikhala kanye nenombolo yamaphoyinti, ngokuzenzakalelayo futhi ngokuqhubekayo ichashazi, futhi ngokuzenzakalela.
