Iyo nzira uye tekinoroji zvinodiwa pakugadzirwa kwepamusoro-simba mabhaudhi

1. Kusarudzwa kwezvinhu
Carbon simbi ine yakanakisa machinability, inogona kusangana neyakasiyana-siyana yesimba musanganiswa wekuita, uye ine mutengo wakaderera kana uchienzaniswa nezvimwe zvinosimbisa zvinhu.
Iyo michina yekabhoni simbi inonzwa kune kabhoni yemukati, iyo kazhinji iri pasi pe1.0%. Isu tinowanzo kusiyanisa yakaderera kabhoni simbi (C% ≤ 0.25%), yepakati kabhoni simbi (0.25% 0.45%), uye alloy simbi (inowedzera alloying zvinhu kune yakajairwa kabhoni simbi) zvichibva pane kabhoni yemukati mune kabhoni simbi zvinhu.
2. Spheroidization (softening) annealing
(1) Kana spheroidized (yakapfava) annealed countersunk head screws uye hexagonal cylindrical head bolts inogadzirwa uchishandisa inotonhora musoro tekinoroji, iyo yekutanga chimiro chesimbi inokanganisa zvakananga kuumba kugona panguva yekutonhora musoro kugadzirisa. Munguva yekutonhora kwemusoro maitiro, deformation yepurasitiki munzvimbo dzemunharaunda inogona kusvika 60% -80%. Nokudaro, zvinotarisirwa kuti simbi inofanira kuva nepurasitiki yakanaka.
(2) Yepakati kabhoni simbi uye yepakati kabhoni alloy simbi ine huwandu hukuru hwehigh-simba fasteners, spheroidization (kunyorovesa) annealing inofanira kuitwa isati yatonhora kuenda kunotora yunifomu uye yakanaka spheroidized pearlite, kuitira kuti zvizadzise zvirinani zvinodikanwa zvekugadzira.
3. Kudhirowa kwewaya
Tambanudza dhisiki uye shandisa rinoenderana rinodhonza simba kwariri kuti uwane inodiwa waya dhayamita (kureva dhayamita) yekugadzira.
Iyo yakagadziriswa waya dhayamita mamakisi ezvizhinji zvakatenderedza mahwendefa mune zvigayo zvesimbi anosanganisira M8, M10, M12, M16, nezvimwewo. Haagone kushandiswa zvakananga kugadzira bhaudhi. Semuyenzaniso, kugadzira dhayamita gumi remamita dhayamita rakazara bhaudhi kunoda kudhonza dhayamita yedhisiki kusvika pa8.78+0.04mm, uku kugadzira bhaudhi re 16mm kunoda waya dhayamita ye14.38+0.02mm.
4.Cold forging
Kugadzirwa kwe hex boltmusoro unotora inotonhora yekugadzira purasitiki kugadzirisa. Kuenzaniswa nekucheka kwekucheka, iyo simbi fiber (simbi waya) inoenderera pamwe nechigadzirwa chimiro pasina kucheka pakati, nekudaro inovandudza chigadzirwa chesimba uye kuwana yakanakisa michina zvinhu. Iyo inotonhora musoro yekugadzira maitiro inosanganisira kucheka nekugadzira, imwe chiteshi kudzvanya kamwechete, kudzvanya kaviri kutonhora musoro, uye akawanda chiteshi otomatiki inotonhora musoro.
6. Thread processing
Shinda dzemabhaudhi dzinowanzogadziriswa nekutonhora kushanda, umo tambo dzisina chinhu mukati meimwe dhayamita renji dzinokwizwa (kukungurutswa) nescrew plate (fa), uye tambo dzinoumbwa nekumanikidza kwescrew plate (rolling die). Iyo yepurasitiki yekuyerera kweiyo yakarukwa chikamu inogona kuwanikwa isina kuchekwa, zvichikonzera kuwedzera kwesimba, kurongeka kwepamusoro, uye yunifomu yemhando yechigadzirwa, iyo inoshandiswa zvakanyanya.
Chinhu chakajairika chekukungurusa (kukwesha) tambo kugadzirisa ndechekuti kumhanyisa kumhanya hakudi kuve kwakanyanya. Kana yakanyanya kukwirira, kushanda kwakaderera uye pamusoro pemazino eshinda kunowanzoita kupatsanurwa kana kusagadzikana tambo. Kusiyana neizvi, kana huwandu hwemarevolutions hwakanyanya kuderera, dhayamita yeshinda inotadza kurasikirwa nekutenderera, uye kudzvanywa kwekutanga panguva yekukunguruka kunowedzera zvisina kujairika, zvichikonzera hupenyu hwakapfupikiswa.
7. Kurapa kwekupisa
Kupisa kurapwahigh-simba fastenersinofanirwa kurapwa nekudzimisa uye nekudzimisa zvinoenderana nezvinodiwa zvehunyanzvi kuti uvandudze huwandu hwemichina yezvimisikidzo uye kusangana neyakatsanangurwa tensile simba kukosha uye goho reshiyo yechigadzirwa.
Nekuda kwehukuru hukuru hwekugadzira uye mutengo wakaderera wemabhaudhi akasimba, pamwe nekudzikama uye kurongeka kwechikamu chakarukwa, zvinodikanwa kuti michina yekupisa kupisa inofanirwa kuve nekuenderana kwakasimba kwekugadzira, dhigirii yepamusoro ye automation, uye kupisa kwakanyanya kunaka kwemhando. Kuti ugadzire zvisungo zvemhando yepamusoro-soro, tekinoroji yekupisa tekinoroji yakakosha.
