Kurapa kwekupisa kwepamusoro kwakakamurwa kuita zvikamu zviviri: 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 kuomarara tester inogona kushandiswa pakuomarara kuyedzwa.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 nzvimbo yekuomarara seyakatetepa kunge 0.05mm gobvu.Kururama kwaro kwakakwirira uye kunogona kusiyanisa ma workpieces anopisa.Musiyano mudiki mukuomarara kwepamusoro, mukuwedzera, kudzika kweiyo inoshanda yakaomeswa layer inowonekwawo neiyo Vickers kuomarara tester, saka zvinodikanwa kushongedza Vickers kuomarara tester yezvikamu zvinoitisa kupisa kwekupisa kupisa kana kushandisa nhamba huru. kwepamusoro kupisa kupisa 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 akaomeswa kudzika kunodarika 0.1mm.Kunyangwe iko kurongeka kweiyo Rockwell hardness tester haina kukwirira seyeVickers hardness tester, inogona kutozadzisa zvinodiwa senzira yekuona yekutarisira kunaka 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 yekuyedza 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 yekuyedza 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 inopfuura 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 yekuomarara kwepamusoro kuyedzwa kwemakemikari kupisa yakagadziriswa workpieces yakafanana nekuomarara kuyedzwa kwepamusoro kudzima kupisa kwakabatiswa workpieces.Vickers kuomarara testers, pamusoro Rockwell kuomarara testers kana Rockwell kuomarara testers anogona kushandiswa.Kuomarara tester kuona, chete ukobvu hwe nitriding gobvu ndiyo yakatetepa, kazhinji isingapfuuri 0.7mm, ipapo Rockwell kuomarara 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. kuyedzwa kwezvikamu kunofanirwa kuitirwa 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 yekuyedza inogona kushandiswa kuyedza iyo HRN kuomarara kukosha.
