1 Kukonzekera musanayesedwe
1) The hardness tester ndi indenter yomwe imagwiritsidwa ntchito poyesa kuuma kwa Vickers iyenera kutsatira zomwe GB/T4340.2;
2) Kutentha kwa chipinda kuyenera kuyendetsedwa mkati mwa 10 ~ 35 ℃. Pamayeso omwe ali ndi zofunikira zolondola kwambiri, ziyenera kuyendetsedwa pa (23±5) ℃.
2 Zitsanzo
1) Tsamba lachitsanzo liyenera kukhala lathyathyathya komanso losalala. Ndibwino kuti chitsanzo cha roughness chapamwamba chiyenera kukwaniritsa zofunikira: Kuchuluka kwapamwamba kwapamwamba kwapamwamba: Vickers kuuma chitsanzo 0.4 (Ra) / μm; katundu wochepa wa Vickers kuuma chitsanzo 0.2 (Ra)/μm; Micro Vickers kuuma chitsanzo 0.1 (Ra)/μm
2) Kwa ma Vickers ang'onoang'ono ndi zitsanzo za Vickers yaying'ono, tikulimbikitsidwa kusankha kupukuta koyenera ndi electrolytic kupukuta kwa mankhwala apamwamba malinga ndi mtundu wa zinthu.
3) makulidwe a chitsanzo kapena wosanjikiza mayeso ayenera kukhala osachepera 1.5 nthawi diagonal kutalika kwa indentation.
4) Mukamagwiritsa ntchito katundu wochepa ndi ma Vickers ang'onoang'ono poyesa, ngati chitsanzocho ndi chaching'ono kwambiri kapena chosasinthika, chitsanzocho chiyenera kuikidwa kapena kutsekedwa ndi chipangizo chapadera chisanayesedwe.
3Njira yoyesera
1) Kusankhidwa kwa mphamvu yoyesera: Malingana ndi kuuma, makulidwe, kukula, ndi zina za chitsanzo, mphamvu yoyesera yomwe ikuwonetsedwa mu Table 4-10 iyenera kusankhidwa kuti iyesedwe. .
2) Nthawi yoyeserera mphamvu yoyeserera: Nthawi kuyambira pakuyamba kugwiritsa ntchito mphamvu mpaka kumaliza ntchito yonse yoyeserera iyenera kukhala mkati mwa 2 ~ 10 s. Kwa mayeso ang'onoang'ono a Vickers ndi ma Vickers ang'onoang'ono a kuuma, kuthamanga kwa inndenter sikuyenera kupitirira 0.2 mm / s. Nthawi yoyesa mphamvu ndi 10 ~ 15 s. Pazinthu zofewa, nthawi yogwira imatha kukulitsidwa, koma cholakwikacho chiyenera kukhala mkati mwa 2.
3) Mtunda wochokera pakati pa indentation mpaka pamphepete mwa chitsanzo: Zitsulo, zamkuwa ndi zamkuwa ziyenera kukhala zosachepera 2.5 kutalika kwa diagonal kutalika kwa indentation; zitsulo zopepuka, kutsogolera, malata ndi ma aloyi awo ziyenera kukhala zosachepera katatu kutalika kwa diagonal wa indentation. Mtunda pakati pa malo awiri oyandikana nawo: zitsulo, mkuwa ndi aloyi zamkuwa, ziyenera kukhala zosachepera 3 kutalika kwa mzere wa diagonal wa chizindikiro choyimitsa; kwa zitsulo zopepuka, lead, malata ndi ma aloyi awo, ziyenera kukhala zosachepera 6 kutalika kwa mzere wozungulira wa indentation.
4) Yezerani tanthauzo la masamu a kutalika kwa ma diagonal awiri a indentation, ndikupeza mtengo wa Vickers kuuma molingana ndi tebulo, kapena kuwerengera mtengo wa kuuma molingana ndi chilinganizo.
Kusiyana kwa kutalika kwa ma diagonal awiri a indentation pa ndege sikuyenera kupitirira 5% ya mtengo wapakati wa ma diagonal. Ngati ipitilira, iyenera kuzindikirika mu lipoti la mayeso.
5) Poyesa pazitsulo zokhotakhota pamwamba, zotsatira zake ziyenera kukonzedwa molingana ndi tebulo.
6) Nthawi zambiri, tikulimbikitsidwa kuti tifotokozere za kuuma kwa mfundo zitatu pa chitsanzo chilichonse.
4 Gulu la Vickers hardness tester
Pali mitundu iwiri ya oyesa kuuma kwa Vickers. Zotsatirazi ndikuyambitsa kagwiritsidwe kake ka Vickers hardness tester:
1. Mtundu wa kuyeza kwa eyepiece;
2. Mapulogalamu amtundu wa kuyeza
Gulu 1: Mtundu wa muyeso wa diso Mawonekedwe: Gwiritsani ntchito diso kuyeza. Kagwiritsidwe: Makinawa amapanga (diamond ◆) indentation, ndipo kutalika kwa diagonal kwa diamondi kumayesedwa ndi diso kuti apeze mtengo wa kuuma.
Gulu 2: Mtundu woyezera mapulogalamu: Zowoneka: Gwiritsani ntchito pulogalamu yolimba kuti muyeze; zosavuta komanso zosavuta m'maso; akhoza kuyeza kuuma, kutalika, kupulumutsa zithunzi za indentation, malipoti a nkhani, etc. Kugwiritsa ntchito: Makinawa amapanga (diamond ◆) indentation, ndipo kamera ya digito imasonkhanitsa indentation pa kompyuta, ndipo mtengo wa kuuma umayesedwa pa kompyuta.
5Gulu la mapulogalamu: Mitundu 4 yoyambira, mtundu wowongolera wa turret, mtundu wa semi-automatic, ndi mtundu wodziwikiratu.
1. Basic Version
Amatha kuyeza kuuma, kutalika, kusunga zithunzi za indentation, malipoti otulutsa, ndi zina zotero;
2.Control automatic turret version software can control the hardness tester turret, monga, lens cholinga, indenter, loading, etc.;
3.Semi-automatic version ndi tebulo lamagetsi la XY lamagetsi, bokosi loyendetsa nsanja la 2D; Kuphatikiza pa ntchito yamtundu wa turret, pulogalamuyo imathanso kukhazikitsa malo ndi mfundo, madontho odziwikiratu, kuyeza kwake, ndi zina zambiri;
4.Fully automatic version with electric XY test table, 3D platform control box, Z-axis focus; Kuphatikiza pa semi-automatic version ntchito, pulogalamuyo imakhalanso ndi Z-axis focus function;
6Momwe mungasankhire oyesa kuuma kwa Vickers
Mtengo wa Vickers hardness tester udzasiyana malinga ndi kasinthidwe ndi ntchito.
1. Ngati mukufuna kusankha zotsika mtengo, mutha kusankha:
Zida zokhala ndi chophimba chaching'ono cha LCD ndi kulowetsa kwa diagonal pamanja kudzera pachocho;
2. Ngati mukufuna kusankha chipangizo chotsika mtengo, mutha kusankha:
Zida zokhala ndi chophimba chachikulu cha LCD, chojambula chamaso chokhala ndi encoder ya digito, ndi chosindikizira chomangidwa;
3. Ngati mukufuna chipangizo chapamwamba kwambiri, mutha kusankha:
Zipangizo zokhala ndi chojambula chojambula, chojambulira chotsekeka, chojambula chamaso chokhala ndi chosindikizira (kapena USB flash drive), screw gear yokweza nyongolotsi, ndi encoder ya digito;
4. Ngati mukuganiza kuti kuyeza ndi chotchinga m’maso n’chotopetsa, mutha kusankha:
Okonzeka ndi makina opangira zithunzi za CCD kuuma, kuyeza pakompyuta popanda kuyang'ana diso, lomwe ndi losavuta, lachidziwitso, komanso lachangu. Mutha kupanganso malipoti ndikusunga zithunzi za indentation, ndi zina.
5. Ngati mukufuna ntchito yosavuta komanso makina apamwamba, ndiye kuti mutha kusankha:
Makina oyesa kuuma a Vickers komanso oyesa kuuma kwa Vickers
Mawonekedwe: ikani masinthidwe ndi kuchuluka kwa mfundo, madontho okha komanso mosalekeza, ndikudziyezera zokha.
