Izvo zvinoputika zvinokonzera kufa kwemhete zvakaoma uye zvinofanirwa kuongororwa zvakadzama.Asi inogona kunyanya kupfupikiswa sezvikonzero zvinotevera.
1. Zvinhu zvinoshandiswa mumhete yemhete ndechimwe chezvikonzero zvakakosha.Parizvino, 4Cr13 uye 20CrMnTid inonyanya kushandiswa munyika yedu, iyo yakagadzikana.Asi iyo inogadzira zvinhu zvakasiyana, kune imwecheteyo zvinhu, trace elements ichava neimwe gap, ichakanganisa kunaka kwemhete mold.
2. Forging process.Ichi chinhu chakakosha chinongedzo mukugadzira mold process.Kune yakakwira alloy simbi mold, izvo zvinodiwa zvekugovera carbide uye imwe metallographic chimiro zvinowanzoiswa pamberi.Izvo zvinodikanwawo kunyatso kudzora tembiricha yekubikira, kugadzira iyo chaiyo yekupisa maratidziro, kutora nzira chaiyo yekuforoma, uye kunonoka kutonhora kana kunonoka kudzoreredza mushure mekugadzira.Isiri-yakajairwa maitiro iri nyore kutungamira kune kutsemuka kwemhete kufa muviri.
3. Gadzirira kurapwa kwekupisa.Zvinoenderana neyakasiyana midziyo uye zvinodiwa zvefa, annealing, tempering uye mamwe ekugadzirira kupisa kupisa maitiro anoteedzana anoshandiswa kuvandudza chimiro, kubvisa hurema hwechimiro chefogi uye chisina chinhu, wozovandudza kushanda.Mushure mekugadzirira kwakakodzera kupisa kurapwa kwepamusoro kabhoni alloy simbi kufa, iyo network carbide inogona kubviswa, iyo inogona kuita iyo carbide spheroidized uye yakanatswa, uye kugovera kufanana kwecarbide kunogona kusimudzirwa.Izvi zvinobatsira kuve nechokwadi chekudzima, kudzikamisa mhando, kunatsiridza hupenyu hwesevhisi ye mold.
Pellet mill kufa kupisa kurapwa
1. Kudzima uye kutsamwa.Ichi ndicho chinongedzo chakakosha mukurapa kupisa kwekufa.Kana kupisa kukaitika panguva yekudzima kupisa, hazvizongokonzeresa brittleness yakakura yeworkpiece, asi zvakare nyore kukonzera deformation uye kuputika panguva yekutonhora, izvo zvinokanganisa zvakanyanya hupenyu hwebasa re mold.Iyo nzira yekurapa yekupisa inofanirwa kudzorwa zvakanyanya uye vacuum kupisa kurapwa kunofanirwa kugamuchirwa.Kudzikamisa kunofanira kuitwa nenguva mushure mekudzima, uye zvinoenderana nezvinodiwa zvehunyanzvi kuti utore nzira dzakasiyana dzekupisa.
2. Kushungurudzika-kuderedza annealing.Kufa kunofanira kuiswa pasi pekunetseka-kuderedza kurapwa kwekugadzirisa mushure mekugadzira rough machining, kuitira kuti kubvisa kushushikana kwemukati kunokonzerwa nekugadzirisa machining, kuitira kuti urege kudzivirira kusvibiswa kwakanyanya kana kuputika kunokonzerwa nekudzima.Kune iyo inofa ine yakanyanya kurongeka inodiwa, inoda zvakare kuitiswa kushushikana-kudzoreredza kurapwa mushure mekugaya, izvo zvinobatsira kudzikamisa kufa chaiko uye kugadzirisa hupenyu hwesevhisi.
Kuvhura gomba chiyero chemhete kufa
Kana chiyero chekuvhura chegomba chekufa chakanyanya kukwira, mukana wekuputika kwemhete kuchawedzera.Nekuda kweyero yakasiyana yekupisa kupisa pamwero uye maitiro, pachave nemusiyano mukuru pakati peumwe neumwe mugadziri wekufa kwemhete.Kazhinji, chigayo chedu chinofa chinogona kuvandudza mwero wekuvhura gomba ne2-6% pahwaro hwekutanga-kirasi brand mold, uye inogona kuve nechokwadi chehupenyu hwesevhisi yemhete mold.
Pellet chigayo chinofa kupfeka
humwe ukobvu uye simba rakaderedzwa kusvika padanho rekuti harigone kutakura kudzvanywa kwegranulation, kuputika kuchaitika.Zvinokurudzirwa kuti kana mhete inofa yakapfekwa kune iyo parallel roller shell groove, iyo mhete inofa inofanira kutsiviwa nenguva.
Kana chigayo chepellet chikafa mukugadzira granulation, huwandu hwezvinhu zviri muguyo hunofa hahugone kushanda pa100%.Kunyangwe goho re ring die granulation rakakwira, asi nguva yakareba yakadaro yekushanda kwesimba guru, ichaitawo. kutungamirira pakutsemuka kwemhete kufa.Isu tinokurudzira kutonga pa75-85% yemutoro kuti ive nechokwadi chekuti hupenyu hwebasa remhete hunofa.
Kana iyo mhete ikafa uye iyo press roll yakatsikirirwa zvakanyanya, zviri nyore kutsemuka.Kazhinji, isu tinoda kuti chinhambwe chiri pakati pemhete kufa uye kudhinda roll ridzorwe pakati pe0.1-0.4mm.
sundries
Zviri nyore kutsemuka kana zvinhu zvakaoma sesimbi zvinoonekwa mupelleting material.
Kuiswa kwemhete kufa uye pellet muchina
Kuiswa kwemhete kufa hakuna kusimba, pachava nemukaha pakati pemhete kufa uye pellet muchina, uye mhete inofa inoputika ichaitikawo mukuita pelleting.
Mushure mekurapwa kwekupisa, mhete inofa icharemara zvakanyanya.Kana isina kugadzirwa, iyo ring inofa ichatsemuka mukushandiswa.
Kana muchina wepellet pachawo uine hurema, senge shaft huru yemuchina wepellet uchizununguka.
