Chitubu simbiinogona kukamurwa kuita chitubu chinopisa chekugadzira uye chinotonhora chekugadzira chitubu zvinoenderana nenzira dzakasiyana dzekuumba.
Kupisa kurapwa kwezvitubu zve thermoforming. Zvitubu zveThermoforming zvinoshandiswa kugadzira zvitubu zvezvimiro zvakakura kana zvakaoma. Kazhinji, kudzima kupisa kunosanganiswa nekugadzira. Kureva kuti, tembiricha yekudziya yakakwira zvishoma pane tembiricha yekudzima (830 ℃ ~ 880 ℃), mushure mekupisa, kupisa coil kuumbwa kunoitwa, uye ipapo kupisa kwemarara kunodzimwa, uye pakupedzisira tembiricha yepakati inoitwa pa 350 ℃ ~ 450 ℃, kuitira kuti uwane iyo yakadzikama tretinite chimiro.
Hunhu hwepamusoro hwesimbi yechirimo hwakakosha zvakanyanya nekuda kwehukuru hwayo hwekutenderera uye kubhenda kushushikana. Surface decarburization ndiyo yakanyanya taboo, inoderedza zvakanyanya simba rekuneta kwesimbi. Nokudaro, kupisa kwekushisa, nguva yekupisa uye kupisa kwepakati kunofanira kubhadhara kusarudzwa uye kutonga. Uye zvakare, kupfurwa kudongorera mushure mekupisa kunobatsirawo kubvisa kuremara kwepamusoro senge decarburization, kutsemuka, inclusions uye mamaki, uye kusimbisa pasi kuti igadzire yakasara yekumanikidza kushushikana uye kugadzirisa kuneta kwesimba rechirimo.
Kupisa kurapwa kwekutonhora kuumba zvitubu. Cold-yakaumbwa chitubu simbi kutanga pashure quenching, tempering kurapwa, kana pashure isothermal quenching, uye ipapo kuburikidza kutonhora kudhirowa kuwana yakakwirira simba simbi waya, uye ipapo kushandisa simbi iyi waya zvakananga kumonera inodiwa chitubu. Ichi chitubu hachichaumbwa mushure mekudzima kurapwa, chete 180 ~ 370 ℃ yakaderera uye yepakati tembiricha tembiricha, kuitira kubvisa kushushikana kwemukati kunokonzerwa nekuumba. The muchinjikwa-chikamu saizi yerudzi urwu chitubu simbi idiki, maererano quenching uye tempering muitiro asati kuumba rakakamurwa mafuta tempering simbi waya uye nokukurumidza isothermal kurapwa kutonhora kudhonzwa simbi waya. Iyo yekutanga ndeyekudzima mafuta + ine mwero tembiricha tempering kurapwa; Iyo yekupedzisira inoreva yekugezesa inotungamira (500 ~ 550 ℃) isothermal quenching kuita sotenite shanduko, uyezve kuburikidza akati wandei kutonhora kudhirowa kusimbisa.
Kana iyo chitubu waya dhayamita yakakura kwazvo, senge Φ> 15mm, ndiro ukobvu h> 8mm, pachava nekudzima opaque chiitiko, zvichikonzera kuderedzwa kweiyo elastic muganho, kuneta simba, saka chitubu kuoma kwesimbi kunofanirwa kuchinjika kune dhayamita yechirimo zvinhu.
