Leeb Kuomarara Tester
Parizvino, Leeb hardness tester inoshandiswa zvakanyanya mukuyedza kuomarara kwe castings. Leeb hardness tester inoshandisa musimboti we dynamic hardness testing uye inoshandisa tekinoroji yekombuta kuita miniaturization uye electronicization ye hardness tester. Zviri nyore uye zviri nyore kushandisa, kuverenga kwacho kuri nyore kunzwisisa, uye mhedzisiro yebvunzo inogona kushandurwa nyore nyore kuita Brinell hardness values, saka inogamuchirwa nevakawanda.
Mazhinji ma castings anoshandiswa pakati nepakati kusvika pakukura, mamwe acho anorema matani akati wandei, uye haagone kuyedzwa pa bench-top hardness tester. Kuedza kwakanyatsonaka kwe castings kunonyanya kushandisa cast test rods kana test blocks zvakasungirirwa pa castings. Zvisinei, test bar kana test block hazvigone kutsiva zvachose workpiece pachayo. Kunyangwe iri furnace imwe chete yesimbi yakanyungudutswa, maitiro ekukanda uye mamiriro ekupisa akafanana. Nekuda kwemusiyano mukuru muhukuru, mwero wekupisa, kunyanya mwero wekutonhodza, uchasiyana. Zvakaoma kuita kuti maviri acho ave nekuoma kwakafanana. Nechikonzero ichi, vatengi vazhinji vanokoshesa uye vanotenda mukuoma kwe workpiece pachayo. Izvi zvinoda portable precision hardness tester kuti iedze kuoma kwe castings. Leeb hardness tester inogadzirisa dambudziko iri, asi zvakakosha kutarisisa kumagumo e workpiece panguva yekushandisa Leeb hardness tester. Leeb hardness tester ine zvinodiwa zvekuoma kwe workpiece.
Brinell Kuomarara Tester
Brinell hardness tester inofanira kushandiswa pakuedza kuomarara kwe castings. Kune grey iron castings dzine tsanga dzakakora, mamiriro ekuedza e3000kg force uye 10mm ball anofanira kushandiswa zvakanyanya sezvinobvira. Kana saizi yekukanda iri diki, Rockwell hardness tester inogonawo kushandiswa.
Zvishandiso zvesimbi zvinowanzova nechimiro chisina kuenzana, zviyo zvakakura, uye zvine kabhoni yakawanda, silicon nezvimwe zvisina kuchena kupfuura simbi, uye kuomarara kunosiyana munzvimbo diki dzakasiyana kana panzvimbo dzakasiyana. Chinongedzo cheBrinell hardness tester chine saizi yakakura nenzvimbo yakakura yekudzika, uye chinogona kuyera avhareji yehukosha hwezvinhu mukati meimwe nzvimbo. Nokudaro, Brinell hardness tester ine kunyatsojeka kwekuyedza uye kupararira kudiki kwehukosha hwekuoma. Hukosha hwekuoma hwakayerwa hunomiririra kuomarara chaiko kwechishandiso chebasa. Nokudaro, Brinell hardness tester inoshandiswa zvakanyanya muindasitiri yekugadzira foundry.
Kuomarara kweRockwell
Zviyedzo zvekusimbisa kuomarara zveRockwell zvinowanzo shandiswawo pakuyedza kuomarara kwesimbi yakakandwa. Kune zvishandiso zvebasa zvine tsanga dzakatsetseka, kana pasina nzvimbo yakakwana yekuyedza kuomarara kweBrinell, bvunzo yekusimbisa kuomarara yeRockwell inogonawo kuitwa. Kune simbi yakakandwa inonyungudika, simbi yakakandwa inotonhorera uye simbi yakakandwa, HRB kana HRC scale inogona kushandiswa. Kana zvinhu zvisina kuenzana, kuverenga kwakawanda kunofanirwa kuyerwa uye kukosha kweavhareji kunofanirwa kutorwa.
Muedzo weKuoma kweGungwa
Muzviitiko zvakasiyana-siyana, kune mamwe ma castings ane maumbirwo makuru, hazvibvumirwi kucheka sampuro, uye hazvibvumirwi kukanda mamwe ma test blocks ekuyedza kuomarara. Panguva ino, kuyedza kuomarara kuchasangana nematambudziko. Panyaya iyi, nzira yakajairika ndeyekuyedza kuomarara ne portable Shore hardness tester panzvimbo yakatsetseka mushure mekunge casting yapera. Semuenzaniso, mu roll standard inoshandiswa zvakanyanya muindasitiri yesimbi, zvinotarisirwa kuti Shore hardness tester inofanira kushandiswa kuyedza kuomarara.
