Maitiro ekusarudza chinhu chakakodzera chekuedza kuomarara kwesimbi yekabhoni

Patinenge tichiongorora kuomarara kwesimbi yekabhoni ine kuomarara kwakaderera, tinofanira kusarudza chinhu chinoedza kuomarara zvine musoro kuti tive nechokwadi chekuti mhinduro dzebvunzo dzacho dzakarurama uye dzinoshanda. Tinogona kufunga nezvekushandisa chiyero cheHRB chechinhu chinoedza kuomarara cheRockwell.

Chikero cheHRB cheRockwell hardness tester chinoshandisa simbi bhora indenter ine dhayamita ye1.588mm uye simba rekuyera rinoenzana re100KG. Range yekuyera yechikero cheHRB yakaiswa pa20-100HRB, iyo yakakodzera kuyedzwa kwekuomarara kwezvinhu zvakawanda zvesimbi yakatenderera yecarbon ine kuomarara kwakaderera.

1. Kana bhaa resimbi yekabhoni rakatenderera radzimwa uye rine kuomarara kwakanyanya kweHRC40 - HRC65, unofanirwa kusarudza Rockwell hardness tester. Rockwell hardness tester iri nyore uye inokurumidza kushanda, uye inogona kuverenga zvakananga kukosha kwekuomarara, iyo yakakodzera kuyera zvinhu zvekuomarara kwakanyanya.

2. Kune mamwe mabhara akatenderera esimbi yekabhoni akagadziriswa ne carburizing, nitriding, nezvimwewo, kuomarara kwenzvimbo kwakakwira uye kuomarara kwepakati kwakaderera. Kana zvichidikanwa kuyera kuomarara kwenzvimbo nemazvo, muyedzi weVickers hardness tester kana muyedzi wemicrohardness tester anogona kusarudzwa. Kudzika kweVickers hardness test kwakaenzana, uye kukosha kwekuomarara kunoverengerwa nekuyera kureba kwe diagonal. Kurongeka kwekuyera kwakakwira uye kunogona kuratidza nemazvo kuchinja kwekuomarara pamusoro pechinhu.

3. Pamusoro pechikero cheHRB chemuyedzo wekuomarara weRockwell, muyedzo wekuomarara weBrinell unogona kushandiswawo kuyedza zvinhu zvesimbi yekabhoni ine kuomarara kwakaderera. Pakuyedza mitsetse yakatenderera yesimbi yekabhoni, muyedzo wayo unosiya nzvimbo yakakura yekudzika pamusoro pechinhu, iyo inogona kuratidza kuomarara kweavhareji yezvinhu. Munguva yekushanda kwemuyedzo wekuomarara, muyedzo wekuomarara weBrinell hausi wekukurumidza uye uri nyore semuyedzo wekuomarara weRockwell. Muyedzo wekuomarara weBrinell ichiyero cheHBW, uye mitsetse yakasiyana inoenderana nesimba rekuyedza. Kune mitsetse yakatenderera yesimbi yekabhoni ine kuomarara kwakaderera, senge iri muchimiro che annealed, kuomarara kunowanzova paHB100 - HB200, uye muyedzo wekuomarara weBrinell unogona kusarudzwa.

4. Kune simbi yakatenderera ine dhayamita hombe uye chimiro chakajairwa, vanhu vakasiyana-siyana vanoedza kuomarara vanowanzo shanda. Zvisinei, kana dhayamita yebhara rakatenderera iri diki, senge pasi pe10mm, Brinell hardness tester inogona kukanganisa kuyera kwakarurama nekuda kwekudzika kukuru. Panguva ino, Rockwell hardness tester kana Vickers hardness tester inogona kusarudzwa. Saizi yavo ye indenter idiki uye inogona kuyera kuomarara kwemasampuru madiki.

5. Kune simbi yakatenderera isina chimiro chisina kurongeka yakaoma kuisa pabhenji remuchina wekuyedza kuomarara wenguva dzose kuti upime, muchina wekuyedza kuomarara unotakurika, wakadai semuchina wekuyedza kuomarara weLeeb, unogona kusarudzwa. Unoshandisa mudziyo wekuyedza kutumira muviri wekurova pamusoro pechinhu chiri kuyerwa, uye unoverenga kukosha kwekuomarara zvichienderana nekumhanya uko muviri wekurova unodzoka. Zviri nyore kushandisa uye zvinogona kuita zviyero panzvimbo yebasa pazvimiro zvakasiyana uye saizi.
