Kurapa kwepamusoro-soro kwakakamurwa kuita mapoka maviri: imwe ndeyekupisa kwepamusoro uye kupisa kupisa kurapwa, uye imwe yacho makemikari kupisa kurapwa.Iyo yakaoma yekuyedza nzira ndeyekutevera:
1. chepamusoro quenching uye tempering kupisa kurapwa
kudzima kwepamusoro uye kupisa kupisa kurapwa kunowanzoitwa nekudziisa induction kana kupisa kwemurazvo.Iwo makuru tekinoroji maparamendi kuoma kwepamusoro, kuomarara kwenzvimbo uye kudzika kwakaoma kwakaomarara.Vickers hardness tester kana Rockwell hardness tester inogona kushandiswa pakuomarara.Kuedza simba Kusarudzwa kunoenderana nekudzika kweiyo inoshanda yakaomeswa layer uye kuoma kwepamusoro kweiyo workpiece.Pane michina mitatu yekuomarara inobatanidzwa pano.
(1) The Vickers hardness tester inzira yakakosha yekuyedza kuomarara kwepamusoro kwezvishandiso zvinopisa zvinopisa.Inogona kushandisa simba rekuyedza re 0.5-100KG kuyedza iyo yekumusoro kuomarara layer yakatetepa kunge 0.05mm gobvu.Kururama kwaro kwakakwirira uye kunogona kusiyanisa ma workpieces anopisa.Musiyano mudiki mukuomarara kwepamusoro, mukuwedzera, kudzika kweiyo inoshanda yakaomeswa layer inowonekwawo neVickers hardness tester, saka zvinodikanwa kushongedza Vickers hardness tester yemayuniti anoita epamusoro kupisa kupisa kurapwa kana kushandisa nhamba huru. zvepamusoro kupisa kupisa workpieces.
(2) Iyo yepamusoro Rockwell kuomarara tester zvakare yakanyatso kuyedza kuomarara kweiyo yepamusoro yakadzimwa workpiece.Pane zviyero zvitatu zveiyo yepamusoro Rockwell kuomarara tester yekusarudza kubva.Inogona kuyedza akasiyana epamusoro akaomeswa workpieces ayo anoshanda akaomeswa kudzika kwakadzika kunodarika 0.1mm.Kunyangwe chokwadi chepamusoro Rockwell hardness tester haina kukwirira seyeVickers hardness tester, inogona kutozadzisa zvinodiwa senzira yekuona yekutonga kwemhando uye kuongororwa kwehunyanzvi hwezvidyarwa zvinopisa kupisa..Besides, inewo maitiro ekushanda nyore, kushandiswa kwakakodzera, mutengo wakaderera, kukurumidza kuyerwa, uye kuverenga zvakananga kwekuoma kwekuoma.Iyo yekumusoro Rockwell kuomarara tester inogona kushandiswa kukurumidza uye isiri-kuparadza kuona mabheji epamusoro-soro-anobatiswa kupisa workpieces rimwe nerimwe.Izvo zvakakosha zvikuru kumafekitari ekugadzira simbi uye kugadzira michina.Kana iyo yekupisa yekupisa yakaomeswa layer yakakora, Rockwell kuomarara tester inogona zvakare kushandiswa.Kana iyo yekupisa yekurapa kuomarara ukobvu iri 0.4-0.8mm, chiyero cheHRA chinogona kushandiswa.Kana iyo yakaomeswa dhizaini kudzika Kana ichipfuura 0.8mm, chiyero cheHRC chinogona kushandiswa.Vickers, Rockwell uye yekumusoro Rockwell matatu kuoma kwakajairwa hunhu hunogona kuchinjirwa nyore kune mumwe nemumwe, kushandurwa kuita zviyero, kudhirowa kana kuomarara kukosha kunodiwa nevashandisi, uye inoenderana tafura yekutendeuka iri mune yepasi rose standard ISO.Iyo American standard ASTM uye Chinese standard GB/T yakapihwa.
(3) Kana ukobvu hweiyo inopisa-yakaomeswa yakaomeswa layer iri pamusoro pe0.2mm, Leeb hardness tester inogona kushandiswa, asi C-type sensor inoda kusarudzwa.Pakuyera, kutarisisa kunofanirwa kubhadharwa kune yekumusoro kupera uye kukora kwese kweiyo workpiece.Iyi yekuyera nzira haina Vickers uye Rockwell Iyo yekuomarara tester ndeyechokwadi, asi yakakodzera kune-saiti kuyerwa mufekitori.
2 makemikari kupisa kurapwa
Kemikari kupisa kwekurapa ndeyekupinza iyo yepamusoro peiyo workpiece ine maatomu eimwe kana akati wandei emakemikari zvinhu, nekudaro ichichinja chimiro chemakemikari, chimiro uye mashandiro epamusoro peiyo workpiece.Mushure mekudzima uye kudziya kwakadzika tembiricha, iyo yepamusoro yeworkpiece ine yakanyanya kuoma uye kupfeka kuramba.uye kubata kuneta simba, uye musimboti weworkpiece ine simba rakawanda uye kuoma.Iyo huru tekinoroji paramita yekemikari kupisa kurapwa workpiece ndiko kudzika kweiyo yakaomeswa layer uye kuoma kwepamusoro.Chinhambwe chinodonhera kuoma kusvika pa50HRC ndiko kudzika kwakaoma kwakaomarara.Iyo yekumusoro kuomarara bvunzo yekemikari inopisa yakabatwa workpieces yakafanana nekuomarara bvunzo dzepamusoro dzakadzimwa kupisa dzakabatwa workpieces.Vickers hardness testers, zvepamusoro Rockwell hardness testers kana Rockwell kuomarara testers zvinogona kushandiswa.Kuomarara tester kuona, iko chete ukobvu hwe nitriding gobvu ndiyo yakatetepa, kazhinji isingapfuuri 0.7mm, ipapo Rockwell hardness tester haigone kushandiswa.
3. kurapwa kwekupisa kwenzvimbo
Kana yomunharaunda kupisa kurapwa zvikamu zvinoda yakakwirira yomunharaunda kuoma, yomunharaunda quenching kupisa kurapwa anogona kuitwa nenzira induction kudziyisa, etc. Nzvimbo dzakadaro dzinowanzoda kutara nzvimbo yemunharaunda quenching kupisa kurapwa uye yomunharaunda kuoma ukoshi pamusoro mufananidzo, uye kuoma. bvunzo dzezvikamu zvinofanirwa kuitwa munzvimbo yakatarwa, iyo kuomarara yekuyedza chiridzwa inogona kushandisa Rockwell kuomarara tester kuyedza iyo HRC kuoma kukosha.Kana iyo yekupisa kurapwa yakaomeswa layer isina kudzika, yekumusoro Rockwell kuomarara tester inogona kushandiswa kuyedza iyo HRN kuoma kukosha.
