Forgingsmuforging process, kupisa kurapwa ndicho chinonyanya kukosha chinongedzo, kupisa kurapwa kunenge annealing, normalizing, quenching uye tempering mana ekutanga maitiro, anowanzozivikanwa sesimbi kupisa kurapwa kwe "moto mina".

imwe, simbi yekupisa kurapwa kwemoto - annealing:
1, annealing ndeyekupisa iyo workpiece kune tembiricha yakakodzera, zvinoenderana neyakagadzirwa uye saizi yebasa uchishandisa nguva yekubata yakasiyana, uye wozononoka kutonhora, chinangwa ndechekuita kuti simbi yemukati sangano isvike kana kuswedera kune equilibrium state, kuwana. kuita kwakanaka kwemaitiro uye kuita, kana kuti kuwedzeredza kudzimwa kwekugadzirira matishu.
2, chinangwa chekuwedzera:

① Kuvandudza kana kubvisa simbi mukukandira, kuforoma, kukungurutsira uye kukwenenzvera kunokonzerwa nekukanganisa kwakasiyana kwesangano uye kusara kunetseka, kudzivirira deformation yebasa rekushanda, kuputika.

② Nyaradza iyo workpiece yekucheka.

③ Natsa zviyo uye uvandudze chimiro kuti uvandudze ma mechanic zvivakwa zve workpiece. (4) Gadzirira kurapwa kwekupisa kwekupedzisira (kudzima, kupisa).
Vaviri, simbi kupisa kurapwa kwechipiri moto - normalizing:
1, normalizing ndeyekupisa iyo workpiece kune yakakodzera tembiricha mushure mekutonhora mumhepo, mhedzisiro ye normalizing yakafanana neannealing, asi chimiro chakanyanya, chinowanzo shandiswa kuvandudza kucheka mashandiro emidziyo, asi zvakare dzimwe nguva inoshandiswa kune zvimwe zvikamu. nezvinodiwa zvakaderera seyekupedzisira kupisa kurapwa.
2, chinangwa che normalizing:
①Iyo inogona kubvisa iyo yakanyanya kupisa yakaomeswa zviyo chimiro uye widnell chimiro chekukanda, forging uye welding zvikamu, uye bhendi chimiro mune inotenderedza zvinhu; Kunatsa zviyo; Uye inogona kushandiswa senge pre-kupisa kurapwa isati yadzima.
② Inogona kubvisa network yechipiri simenti, uye kunatsa iyo pearlite, kwete kungovandudza michina zvivakwa, asiwo inobatsira kune ramangwana spheroidizing annealing.
③Simende yemahara pamuganho wezviyo inogona kubviswa kuti ivandudze iyo yakadzika yekudhirowa kuita.
Tatu, simbi kupisa kurapwa kwechitatu moto - kudzima:
1, kudzima ndeyekupisa iyo workpiece mushure mekuchengetedza kupisa, mumvura, mafuta kana imwe inorganic munyu, organic mvura mhinduro uye imwe quenching yepakati kutonhora nekukurumidza. Mushure mekudzima, simbi inova yakaoma, asi panguva imwechete inova brittle.
2. Chinangwa chekudzima:
①Kuvandudza michina yemidziyo yesimbi kana zvikamu. Semuenzaniso: kunatsiridza kuomarara uye kupfeka kuramba kwezvishandiso, mabhengi, nezvimwe, kuvandudza muganho wakasimba wezvitubu, vandudza iyo yakazara mekiniki zvimiro zveshaft zvikamu, nezvimwe.
②, kunatsiridza zvivakwa kana makemikari zvimiro zveimwe yakakosha simbi. Zvakadai sekuvandudza kushora kwesimbi yesimbi isina tsvina, wedzera magineti echigarire emagineti simbi, nezvimwe.
Ina, simbi yekupisa kurapwa kwechina moto - kupisa:
1, kudziya kuitira kuderedza brittleness yesimbi, kudzima kwesimbi pane imwe tembiricha yakakodzera pamusoro pekamuri tembiricha uye pasi pe710 ℃ kwenguva yakareba, uyezve kutonhora, maitiro aya anonzi tempering.
2, chinangwa chekugadzirisa:
①, kuderedza kushushikana kwemukati uye kuderedza brittleness, kune kushushikana kwakawanda uye brittleness yekudzima zvikamu, senge kusadzora nenguva kunowanzo gadzira deformation uye kunyangwe kuparuka.
② Gadzirisa zvimisikidzo zveiyo workpiece. Mushure mekudzima, iyo workpiece ine yakakwirira kuoma uye brittleness. Kuti usangane nezvinodiwa zvakasiyana-siyana zvekushanda zvakasiyana-siyana, kuoma, simba, plastiki uye kuoma kunogona kugadziriswa nekupisa.
③, dzikamisa saizi yebasa. Nekupisa, iyo metallographic chimiro inogona kudzikamiswa kuti ive nechokwadi chekuti deformation haizoitike mune ramangwana rekushandisa maitiro.
④, kunatsiridza kucheka kweimwe alloy simbi.
