Powder metallurgy rudzi rutsva rwemambure ari pedyo-kuumba tekinoroji, inoshandisa kunyunguduka, kudziyisa, jekiseni uye kudzvanya kwesimbi hupfu kuita inodiwa mold.Kune zvimwe zvakakosha zvinhu senge refractory simbi, refractory simbi, yakakwirira alloy uye zvichingodaro.Saka ndezvipi zvinhu zvinokanganisa kunaka kwepoda metallurgy kudzvanya kuumbwa kwezvikamu zvemotokari?
Ⅰ: Kupesvedzera kwekumanikidza kuumba kufa
Zviri pachena kuti kufa kwakakosha kune inotsikirira yekugadzira tekinoroji.Inokurudzirwa kushandisa iyo yechikadzi die kana mandrel yakagadzirwa necemented carbide, poda yakakwirira-kumhanya simbi uye zvimwe zvinhu.Kana iyo inofa (yakadai semukati yemukati yemukadzi inofa uye yekunze dhayamita ye mandrel) iri kushanda, iyo idiki iyo pamusoro roughness iri, zviri nani kudzikisa friction factor pakati pehupfu particles uye die wall.
Kana iri yakakura kana yakaoma isina chinhu, kudzvanya kwenguva refu kunokonzeresa kuti mold yemukadzi kupisa uye kuremara, mudziyo wekutonhora wemvura unogona kushandiswa kuderedza tembiricha yechikadzi mold uye kuderedza friction factor.
Pamusoro pezvo, mukugadzirwa kwechikadzi mold, isu tinofanirwa kutarisa kusimba uye kusimba, izvo zvinogona kuderedza dhigirii yekupisa deformation yemukadzi mold, kuderedza kurasikirwa kwekumanikidza, uye kudzivirira kutsemuka mukutsikirira zvikamu zvemotokari.
Ⅱ: Mhedzisiro yeforoma uye lubricant
Mukuita kwehupfu metallurgy kudzvanya uye kuumbwa kwezvikamu zvemotokari, nekuda kwekurasikirwa kwekumanikidzwa kunokonzerwa nekukweshana pakati pehupfu hwakasanganiswa nemadziro emuvhu, kuwanda kwekugovera kwema compact hakuna kuenzana.Minxin Powder inokurudzira kushandisa yakaomarara mold kana mafuta ekuzora ari nani.
Ⅲ: Mhedzisiro yemafuta
Kuwedzera lubricant kune simbi yakasanganiswa poda inogona kunyatso kudzikisa kupokana pakati pehupfu uye madziro eforoma, uye kuita kuti density kugovera kweiyo compact iwedzere yunifomu.Iyo inowanzoshandiswa lubricant ndeye zinc stearate.Kunyangwe ichigona kuvandudza kudzvanya nekugadzira mamiriro, zviri nyore kuburitsa kupatsanurwa mushure mekusanganiswa nekuda kweiyo yakaderera density yakasununguka, uye iyo sintered zvikamu zvinowanzoita gomba uye mamwe matambudziko.
Kushandisa lubricant yakanaka kunogona kunyatso kuvandudza kupokana pakati pehupfu uye madziro eforoma, uye kuderedza zvakanyanya density kukanganisa kwekombuta.Muchikamu chekusanganiswa kwehupfu, kutarisa kunofanirawo kubhadharwa kune nzira yekusanganiswa kweupfu, iyo inogonawo kuderedza kupesana.
Ⅳ: Kupesvedzera kwekudzvanya paramita
1: Kumhanyisa kumhanya
Kana iyo yekutsikirira ichimhanya zvakanyanya, inokanganisa kuenzana kwehuremu hwekombikiti, uye ichaburitsawo makatsemuka.Zviri nani kushandisa iyo hydraulic poda yekugadzira muchina wekugadzira.
2: Kumanikidza kubata nguva
Iyo density ye compact inoumbwa nehupfu metallurgy kudzvanya kwezvikamu zvemotokari inogona kuwedzera zvakanyanya pasi pekudzvanyirira kwakakura uye nenguva yekubata.
3: Chimiro chehupfu yekudyisa bhutsu
Kana iyo general poda yekudyisa shangu yakashandiswa kurodha hupfu, inokonzeresa kuzadza hupfu husina kuenzana kumusoro uye kuzasi kwegomba rekuumbwa kana kumberi nekumashure, izvo zvinokanganisa kunaka kweiyo blank.Kuvandudza kana kugadzirisa poda yekudyisa shangu kunogona kuvandudza dambudziko rehupfu hunotakura kufanana.
