Kuti mutengi anzwisise zvakadzama nezveMetal Injection Molding tekinoroji yedu, isu tichataura zvakasiyana nezvese maitiro eMIM, ngatitangei kubva pakuita maitiro nhasi.
Upfu hwekugadzira tekinoroji inzira yekuzadza pre-yakasanganiswa poda mugomba rakagadzirwa, kushandisa imwe kudzvanywa kuburikidza nemuchina kuti ugadzire chigadzirwa chechimiro chakagadzirwa, uye wozobvisa chigadzirwa kubva mugomba nemuchina.
Kugadzira inzira yekutanga simbi yehupfu iyo kukosha kwayo ndeyechipiri chete kune sintering.Iyo inodzivirira zvakanyanya uye inosarudza iyo yese yekugadzira maitiro ehupfu metallurgy kupfuura mamwe maitiro.
1. Kuti nzira yekugadzira ine musoro here kana kuti kwete inotema zvakananga kana ichigona kuenderera zvakanaka.
2. Kukanganisa maitiro anotevera (kusanganisira maitiro ekubatsira) uye kunaka kwechigadzirwa chekupedzisira.
3. Kukanganisa kugadzira otomatiki, kugadzirwa uye mutengo wekugadzira.
Kugadzira muchina
1. Kune marudzi maviri ekufa kwepamusoro mumuchina wekugadzira:
a) Iyo yepakati mold nzvimbo inoyangarara (yakawanda yekambani yedu ine chimiro ichi)
b) Fixed mold surface
2. Kune mhando mbiri dze mold pamusoro pemafomu anoyangarara mumuchina wekuumba:
a) Nzvimbo yekudzikisa inogadziriswa, uye nzvimbo yekugadzira inogona kugadziriswa
b) Nzvimbo yekugadzira inogadziriswa, uye nzvimbo yekudzikisa inogona kugadziriswa
Kazhinji, iyo yakatemerwa mhando yepakati inofa pamusoro inogamuchirwa kune diki yekumanikidza tonnage, uye yepakati inofa pamusoro inoyangarara kune yakakura yekumanikidza tonnage.
Matanho matatu ekuumbwa
1. Kuzadza nhanho: kubva kumagumo ekudzikisa kusvika kumagumo epakati mold surface inokwira kusvika pakakwirira, kona yekushanda yekudhinda inotanga kubva ku270 degrees kusvika ku360 degrees;
2. Pressurization stage: Ndiyo nhanho apo poda inomanikidzwa uye inoumbwa mumhango.Kazhinji kune yekumusoro kufa kudzvanywa uye yepakati kufa pamusoro inodzika (kureva yakaderera press) kudzvanya, dzimwe nguva kune yekupedzisira kudzvanywa, ndiko kuti, iyo yepamusoro punch inodzvanya zvakare mushure mekupera kwekutsikirirwa, iyo kona yekushanda yemuchina inotangira kubva kumadhigirii zana nemakumi maviri. kusvika 180 degrees End;
3. Demolding stage: Iyi nzira ndiyo nzira iyo chigadzirwa chinobudiswa kubva mumhango ye mold.Iko kushanda kwekona yekudhinda kunotanga pa 180 degrees uye kunopera pa 270 degrees.
Density kugoverwa kweupfu compacts
1. One-way kudzvinyirira
Munguva yekutsikirira, chiumbwa chechikadzi hachifambi, iyo yepasi inofa punch (yepamusoro kufa punch) haifambi, uye kudzvinyirira kunongoshandiswa kumuviri wehupfu kuburikidza nepamusoro kufa punch (pasi kufa punch).
a) Mafungiro asina kuenzana density kugovera;
b) Neutral axis chinzvimbo: iyo yakaderera yekupedzisira yekombuta;
c) Kana H, H / D ichiwedzera, iyo density musiyano unowedzera;
d) Yakareruka mold chimiro uye yakakwirira kubereka;
e) Inokodzera ma compact ane hurefu hudiki uye yakakura madziro ukobvu
2. Kudzvinyirira-nzira mbiri
Munguva yekutsikirira, chiumbwa chechikadzi hachifambi, uye mapikisi epamusoro uye epasi anoita kumanikidza paupfu.
a) Izvo zvakaenzana nepamusoro pekudzvinyirira kwenzira mbiri imwe chete;
b) Iyo isina kwayakarerekera shaft haisi pamagumo eiyo compact;
c)Pasi pemamiriro akafanana ekudzvanya, musiyano we density idiki pane unidirectional kudzvanya;
d) Inogona kushandiswa kudzvanya nehukuru H / D compacts
