Nzira yekudzivirira sei kugadzirwa kwekudzima kushushikana panguva yekutonhora modhi?

Saka iwe unodzivirira sei kugadzirwa kwekudzima kushushikana panguva yestandard precision mold basekutonhora?
Kupisa kunofanira kushandiswa kubvisa kushushikana, uye mushure mekudzima kwemhando dzemhando, bikai 30 ~ 60min usati watonhodza kurapwa, kubvisa 15% kusvika 25% kudzima kushushikana, kudzikamisa yakasara aus, yozoitwa - 60 ° C yakajairika kurapwa kana kutonhora kwakadzika. kurapwa kwe -120 ° C.

Iyo yakaderera tembiricha, iyo yakawedzera yakasara austenite shanduko ndiyo nhamba yemartensite, asi hazvibviri kushandura. Mhedzisiro yekuedza inoratidza kuti iyo yakasara austenite accounts inosvika 2% kusvika 5%, uye shoma shoma yakasara austenite inogona kuita inononoka kushushikana uye buffer. Sezvo yakasara austenite yakapfava uye yakaoma, inogona kutora zvishoma simba rekuwedzera kwesimba, kubvisa kushushikana kwechikamu. Mushure mekurapa kunotonhora, iyo yakajairwa modhi inotorwa mumvura inopisa kupisa tembiricha, uye 40% -60% kutonhora kurapwa kunetseka kunogona kubviswa. Kana tembiricha yakwira kusvika kune tembiricha yekamuri, inofanirwa kudzikamiswa nenguva kuti iwedzere kubvisa kutonhora kwekurapa kunetseka, kudzivirira kugadzira kutonhora kwekurapa kutsemuka, kuwana yakagadzikana matishu uye kuita, kuve nechokwadi kuti.standard precision mold base haina kukanganisa panguva yekuchengetedza uye kushandiswa.
