Vickers gukomera kwipimisha uburyo no kwirinda

1 Kwitegura mbere yo kwipimisha

1) Ikizamini cyo gukomera hamwe nindenter zikoreshwa mugupima ubukana bwa Vickers bigomba kubahiriza ibivugwa muri GB / T4340.2;

2) Ubushyuhe bwicyumba bugomba kugenzurwa muburyo bwa 10 ~ 35 ℃. Kubizamini bifite ibisobanuro bisobanutse neza, bigomba kugenzurwa kuri (23 ± 5) ℃.

Ingero

1) Ubuso bw'icyitegererezo bugomba kuba buringaniye kandi bworoshye. Birasabwa ko icyitegererezo cyubuso bugomba kuba cyujuje ibisabwa: Agaciro ntarengwa k'ubuso bukabije: Vickers ubukana bw'icyitegererezo 0.4 (Ra) / μm; umutwaro muto Vickers gukomera urugero 0.2 (Ra) / μm; micro Vickers gukomera icyitegererezo 0.1 (Ra) / μm

)

3) Ubunini bwikitegererezo cyangwa igipimo kigomba kuba byibuze inshuro 1.5 uburebure bwa diagonal ya indentation

4) Iyo ukoresheje umutwaro muto na micro Vickers mugupima, niba icyitegererezo ari gito cyane cyangwa kidasanzwe, icyitegererezo kigomba gushyirwaho cyangwa gufatanyirizwa hamwe bidasanzwe mbere yo kwipimisha.

3Uburyo bwo kugerageza

1) Guhitamo imbaraga zipimisha: Ukurikije ubukana, ubunini, ubunini, nibindi byicyitegererezo, imbaraga zipimisha zerekanwa kumeza 4-10 zigomba gutoranywa kugirango zipimwe. .

2) Igihe cyo gusaba imbaraga zo kugerageza: Igihe cyo gutangira imbaraga zo gusaba kugeza kurangiza imbaraga zose zipimisha zigomba kuba muri 2 ~ 10 s. Kubintu bito bito Vickers na micro Vickers igerageza, umuvuduko wamanuka ntushobora kurenga 0.2 mm / s. Imbaraga zipimisha zifata igihe ni 10 ~ 15 s. Kubikoresho byoroshye cyane, gufata umwanya birashobora kongerwa, ariko ikosa rigomba kuba muri 2.

3) Intera kuva hagati ya indentation kugera kumpera yicyitegererezo: Ibyuma, umuringa n'umuringa bigomba kuba byibuze inshuro 2,5 z'uburebure bwa diagonal ya indentation; ibyuma byoroheje, isasu, amabati hamwe na alloys bigomba kuba byibuze inshuro 3 uburebure bwa diagonal ya indentation. Intera iri hagati yikigo cyibice bibiri byegeranye: kubyuma, umuringa nu muringa, bigomba kuba byibuze inshuro 3 z'uburebure bwumurongo wa diagonal wumurongo uhagarara; ku byuma byoroheje, isasu, amabati hamwe na alloys, bigomba kuba byibuze inshuro 6 z'uburebure bwumurongo wa diagonal ya indentation

4) Gupima imibare yimibare yuburebure bwa diagonal ebyiri za indentation, hanyuma ushake agaciro ka Vickers ukurikije imbonerahamwe, cyangwa ubare agaciro gakomeye ukurikije formula.

Itandukaniro muburebure bwa diagonal ebyiri zerekana indentation mu ndege ntirishobora kurenga 5% byagaciro kagereranijwe ka diagonals. Niba birenze, bigomba kumenyekana muri raporo yikizamini.

5) Mugihe cyo kwipimisha hejuru yicyitegererezo, ibisubizo bigomba gukosorwa ukurikije imbonerahamwe.

6) Muri rusange, birasabwa gutanga raporo yikigereranyo cyikigereranyo cyamanota atatu kuri buri sample.

4 Vickers gukomera kwipimisha

Hariho ubwoko 2 bwibisanzwe bikoreshwa na Vickers. Ibikurikira ni intangiriro kubisanzwe bikoreshwa na Vickers igeragezwa:

1. Ubwoko bwo gupima ijisho;

2. Ubwoko bwo gupima software

Icyiciro cya 1: Ubwoko bwo gupima ijisho Ibiranga: Koresha ijisho ryo gupima. Imikoreshereze: Imashini ikora indangagaciro (diyama ◆), kandi uburebure bwa diagonal bwa diyama bupimwa nijisho kugirango ubone agaciro gakomeye.

Icyiciro cya 2: Ubwoko bwo gupima software ures Ibiranga: Koresha software igoye gupima; byoroshye kandi byoroshye kumaso; Irashobora gupima ubukana, uburebure, kubika amashusho yerekana, gutanga raporo, nibindi. Gukoresha: Imashini ikora indente (diamant ◆), kandi kamera ya digitale ikusanya indentation kuri mudasobwa, kandi agaciro gakomeye gapimirwa kuri mudasobwa.

5Urutonde rwa software.

1. Inyandiko y'ibanze

Irashobora gupima ubukana, uburebure, kubika amashusho yerekana, gutanga raporo, nibindi.;

2.Kontorora yimikorere ya turret verisiyo irashobora kugenzura ubukana bwa tester turret, nka, lens lens, indenter, gupakira, nibindi.;
3.Semi-automatic verisiyo hamwe nimbonerahamwe ya XY yamashanyarazi, agasanduku kagenzura 2D; Usibye imikorere yimikorere ya turret yimikorere, software irashobora kandi gushiraho umwanya n amanota, utudomo twikora, gupima byikora, nibindi.;
4.Uburyo bwuzuye bwikora hamwe nameza yikizamini cyamashanyarazi XY, agasanduku ka 3D igenzura agasanduku, Z-axis yibanze; Usibye igice cyikora-verisiyo yimikorere, software nayo ifite imikorere ya Z-axis yibanze;

6Nigute ushobora guhitamo ibizamini bya Vickers bikwiye

Igiciro cya Vickers igeragezwa rizatandukana bitewe nuburyo n'imikorere.

1. Niba ushaka guhitamo bihendutse, noneho urashobora guhitamo:

Ibikoresho bifite ecran ntoya ya LCD hamwe nintoki ya diagonal yinjiza binyuze mumaso;

2. Niba ushaka guhitamo igikoresho gikoresha ikiguzi, noneho urashobora guhitamo:

Ibikoresho bifite ecran nini ya LCD, ijisho rifite kodegisi ya digitale, hamwe na printer yubatswe;

3. Niba ushaka igikoresho cyo hejuru cyane, noneho urashobora guhitamo:

Ibikoresho bifite ecran yo gukoraho, sensor ifunze-loop, ijisho rifite printer (cyangwa USB flash ya disiki), icyuma cyo kuzamura inyo, hamwe na kodegisi ya digitale;

4. Niba utekereza ko binaniza gupima ukoresheje ijisho, noneho urashobora guhitamo:

Hamwe na sisitemu yo gutunganya amashusho ya CCD, bapima kuri mudasobwa utarebye ijisho, ryoroshye, ryihuse, kandi ryihuse. Urashobora kandi gukora raporo no kubika amashusho yerekana, nibindi.

5. Niba ushaka imikorere yoroshye na automatike yo hejuru, noneho urashobora guhitamo:

Automatic Vickers igerageza igeragezwa hamwe na byimazeyo Vickers igerageza

Ibiranga: shiraho intera numubare wamanota, byikora kandi bikomeza akadomo, hanyuma uhite upima.
