Ruzivo rwekutanga rwesimbi kupisa kurapwa

QY Precision inogona kupedzisa iyo yese CNC Maitiro Maitiro, kusanganisira Kurapa kwekupisa .
Metal kupisa kurapwa inzira iyo simbi workpiece inopisa kune yakakodzera tembiricha mune imwe svikiro, uye mushure mekuchengetwa pane iyi tembiricha kweimwe nguva yenguva, inotonhodzwa nekumhanya kwakasiyana.
1. Metal chimiro
Metal: Chinhu chine opaque, metallic luster, yakanaka kupisa uye magetsi conductivity, uye magetsi ayo emagetsi anodzikira nekuwedzera tembiricha, uye akapfuma muductility uye malleability. Guta (kureva, crystal) umo maatomu ari musimbi anorongwa nguva dzose.
Alloy: Chinhu chine simbi inoumbwa nesimbi mbiri kana kupfuura kana simbi uye dzisiri simbi.
Phase: chikamu cheiyo alloy ine yakafanana kuumbwa, chimiro uye kuita.
Solid solution: Irorosi yesimbi yakasimba umo maatomu (macompounds) echimwe (kana akati wandei)elementi anonyungudika muretisi yechimwe chinhu achiri kuchengetedza mhando yelatisi yechimwe chinhu. Iyo yakasimba mhinduro yakakamurwa kuita interstitial yakasimba mhinduro uye kutsiva Mhando mbiri dzemhinduro yakasimba.
Solid solution yekusimbisa: Sezvo maatomu esolute achipinda mumagapu kana nodes yecrystal lattice inonyungudutsa, crystal lattice inokanganiswa uye kuoma uye kusimba kwechigadziro chakasimba kunowedzera. Chiitiko ichi chinodaidzwa kuti solid solution kusimbisa.
Musanganiswa: Musanganiswa wekemikari pakati pezvikamu zvealloy unoburitsa chimiro chitsva chekristaro chakasimba chine simbi.
Mechanical musanganiswa: Iyo alloy inoumbwa inoumbwa maviri ekristaro zvimiro. Kunyangwe iri kristaro ine mativi maviri, inhengo uye ine yakazvimirira michina zvivakwa.
Ferrite: Iyo interstitial yakasimba mhinduro yekabhoni mu-Fe (iron ine body-centered cubic structure).
Austenite: iyo interstitial yakasimba mhinduro yekabhoni mug-Fe (kumeso-pakati cubic chimiro simbi).
Cementite: musanganiswa wakagadzikana (Fe3c) wakaumbwa nekabhoni nesimbi.
Pearlite: musanganiswa wemuchina unoumbwa neferrite uye simenti (F+Fe3c ine 0.8% kabhoni)
Leeburite: musanganiswa wemuchina unoumbwa necementite uye austenite (4.3% kabhoni)
 
Metal kupisa kurapwa ndeimwe yeakakosha maitiro mukugadzira michina. Kuenzaniswa nemamwe maitiro ekugadzirisa, kupisa kupisa kazhinji hakuchinje chimiro uye yakazara kemikari kuumbwa kweiyo workpiece, asi nekushandura iyo yemukati microstructure yeworkpiece, kana kushandura kemikari yepasi peiyo workpiece, Kupa kana kuvandudza mashandiro. ye workpiece. Chimiro chayo ndechekuvandudza hutano hwemukati we workpiece, iyo inowanzosaonekwa kune ziso rakashama.
Kuti uite simbi workpiece ine inodiwa michina zvivakwa, zvemuviri zvimiro uye makemikari zvimiro, mukuwedzera kune zvine musoro kusarudzwa kwezvinhu uye akasiyana maitiro ekugadzira, maitiro ekurapa kupisa anowanzo kudiwa. Simbi ndiyo inonyanya kushandiswa zvinhu muindasitiri yemuchina. Iyo microstructure yesimbi yakaoma uye inogona kudzorwa nekupisa kurapwa. Nokudaro, kurapwa kwekupisa kwesimbi ndiyo inonyanya kushandiswa kwesimbi inopisa kupisa. Uye zvakare, aruminiyamu, mhangura, magnesium, titanium, nezvimwe uye alloys avo anogona zvakare kupisa kupisa kuti achinje ma mechanic, emuviri uye kemikari zvivakwa kuti awane maitiro akasiyana.
 
Kuita kwezvinhu zvesimbi kunowanzo kukamurwa kuita mapoka maviri: mashandiro ekuita uye mashandiro ekushandisa. Iyo inonzi process performance inoreva kuita kwesimbi zvinhu pasi peiyo yakataurwa inotonhora uye inopisa kugadzirisa mamiriro mukugadzirisa uye kugadzira maitiro emakanika zvikamu. Kuitwa kwemaitiro emidziyo yesimbi kunogadzirisa kuchinjika kwayo mukugadzira maitiro. Pamusana pemamiriro akasiyana-siyana ekugadzirisa, kushandiswa kwemaitiro kunodiwa kwakasiyanawo, zvakadai sekukanda kushanda, weldability, forgeability, kupisa kupisa kushanda, machinability, etc. Izvo zvinonzi kushandiswa kwekushandisa kunoreva kushanda kwesimbi pasi pemamiriro ekushandiswa. yezvikamu zvema mechanical, izvo zvinosanganisira ma mechanical properties, zvinhu zvemuviri, makemikari zvinhu, nezvimwewo.
Muindasitiri yekugadzira makina, majekiseni emuchina anoshandiswa mune yakajairika tembiricha, yakajairwa kudzvanywa uye isina-yakasimba corrosive media, uye imwe neimwe mechanicha chikamu chinotakura mitoro yakasiyana panguva yekushandiswa. Kuitwa kwezvinhu zvesimbi kuramba kukuvara pasi pemutoro kunonzi mechanical properties (kana mechanical properties).
Iyo mechanical properties yezvinhu zvesimbi ndiyo nheyo huru yekugadzira uye kusarudzwa kwezvinhu zvezvikamu. Chimiro chemutoro wakaiswa chakasiyana (sekunetsa, kudzvanya, torsion, kukanganisa, cyclic mutoro, nezvimwewo), uye inodiwa michina zvimiro zvesimbi zvinhu zvichave zvakasiyana. Inowanzo shandiswa michina zvimiro zvinosanganisira: simba, plasticity, kuomarara, kukanganisa kuoma, kuwanda kukanganisa kuramba uye kupera simba.
