Kurapa kwekupisa kwepamusoro kwakakamurwa kuita mapoka maviri: imwe ndeyekudzima kwepamusoro uye kupisa kupisa kurapwa, uye imwe yacho makemikari kupisa kurapwa.Iyo yakaoma yekuyedza nzira ndeyekutevera:
1. pamusoro quenching uye tempering kupisa kurapwa
Kudzima kwepamusoro uye kupisa kupisa kurapwa kunowanzoitwa nekudziisa induction kana kupisa kwemurazvo.Iwo main tekinoroji paramita kuomarara kwepasi, kuomarara kwenzvimbo uye kusimba kwakaomarara kudzika kwakadzika.Vickers hardness tester kana Rockwell hardness tester inogona kushandiswa pakuomarara.Kuedza simba Kusarudzwa kunoenderana nekudzika kweiyo inoshanda yakaoma yakaomeswa uye kuoma kwepamusoro kweiyo workpiece.Pane michina mitatu yekuomarara inobatanidzwa pano.
(1) Iyo Vickers kuomarara tester inzira yakakosha yekuyedza kuomarara kwepamusoro kwezvishandiso zvinopisa zvinopisa.Inogona kushandisa simba rekuyedza re 0.5-100KG kuyedza iyo yekuomesera pasi 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 kurapwa kugadzirisa kana kushandisa nhamba huru. kwepamusoro kupisa kurapwa workpieces.
(2) Iyo yepamusoro Rockwell kuomarara tester zvakare yakanyatso kuyedza kuomarara kwechiso chakadzimwa workpiece.Kune zviyero zvitatu zveiyo Rockwell kuomarara tester yekusarudza kubva.Inogona kuyedza akasiyana epamusoro akaomeswa workpieces ayo anoshanda akaomeswa kudzika kwakadzika kunodarika 0.1mm.Kunyangwe chokwadi cheiyo Rockwell hardness tester haina kukwirira seyeVickers hardness tester, inogona kutosangana nezvinodiwa senzira yekuona yekutarisira kwemhando uye kuongororwa kwehunyanzvi hwezvidyarwa zvinopisa kupisa..Besides, inewo maitiro ekushanda nyore, kushandiswa kwakakodzera, mutengo wakaderera, kukurumidza kuyerwa, uye kuverenga zvakananga kwekuoma kwekuoma.Iyo yepamusoro Rockwell kuomarara tester inogona kushandiswa kukurumidza uye isiri-kuparadza kuona mabheti epamusoro-anopisa-akagadziriswa workpieces rimwe nerimwe.Izvo zvakakosha zvikuru kumafekitari ekugadzira simbi uye kugadzira michina.Kana iyo yekupisa yekupisa yakaomeswa layer yakakora, iyo 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 yepamusoro Rockwell matatu kuoma kwakajairwa hunhu hunogona kuchinjika nyore kune mumwe nemumwe, kushandurwa kuita zviyero, kudhirowa kana kuomarara hunhu hunodiwa nevashandisi, uye inoenderana tafura yekutendeuka iri mune yepasi rose standard ISO.Iyo American standard ASTM uye Chinese standard GB/T yakapihwa.
(3) Kana hupamhi hwekupisa-hunopisa hwakaomeswa hutsika hunopfuura 0.2mm, Leeb kuomarara tester inogona kushandiswa, asi C-mhando sensor inoda kusarudzwa.Pakuyera, kutarisisa kunofanirwa kubhadharwa kumagumo epamusoro uye kuwanda 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 kurapwa ndeyekupinza pamusoro peiyo workpiece nemaatomu eimwe kana akati wandei emakemikari zvinhu, nekudaro kuchinja kemikari, chimiro uye kuita kwepamusoro peiyo workpiece.Mushure mekudzima uye kudziya kwakadzika tembiricha, pamusoro peiyo workpiece 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 kwepasi.Chinhambwe chinodonhera kuoma kusvika pa50HRC ndiko kudzika kwakaoma kwakaomarara.Iyo yekumusoro kuoma bvunzo yemakemikari kupisa yakarapwa workpieces yakafanana nekuomarara bvunzo yepasi yakadzima kupisa yakabatiswa workpieces.Vickers hardness testers, Rockwell hardness testers kana Rockwell kuomarara testers inogona 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 dzinofanirwa kuitirwa munzvimbo yakatarwa, iyo kuomarara yekuedza chiridzwa inogona kushandisa Rockwell kuomarara tester kuyedza iyo HRC kuoma kukosha.Kana iyo yekupisa kurapwa yakaomeswa musara isina kudzika, pamusoro Rockwell kuomarara tester inogona kushandiswa kuyedza iyo HRN kuomarara kukosha.
