Upfu metallurgy (Powder metallurgy, inonzi PM) inonzi metallurgical tekinoroji umo simbi hupfu (kana musanganiswa wesimbi hupfu uye isiri-simbi hupfu) inoshandiswa seyakabikwa kugadzira zvigadzirwa zvesimbi kana zvinhu kuburikidza nekugadzira, sintering kana kupisa kuumba.Iyo poda metallurgy kugadzirwa kwakafanana nekugadzirwa kwezvigadzirwa zveceramic, saka vanhu vanowanzodaidza iyo poda metallurgy nzira "cermet nzira".
Nekukurumidza kusimudzira kwese mafambiro ehupenyu, zvakasiyana zvinodiwa senge lightweight uye compact dhizaini, zvikamu zvakawanda zviri kuramba zvichiwedzera kuoma, zvichiita kuti poda metallurgy molding process itarise mamwe matambudziko.
Nekuwedzera kwehuwandu hwePM, zvinodiwa zvekugadzirisa zvinosungirwa kuva zvakasimba.Sechishandiso chakanyanya kunetsa pane poda metallurgy chikamu chekugadzira mutsara, iyo poda inogadzira hydraulic press inosarudza kunaka kwehupfu compact uye inorambidza kusimukira kweindasitiri yehupfu simbi muChina..Iyo yepamusoro-inoshanda poda yekutsikirira ihupfu inogadzira hydraulic press product yakavakirwa paelectro-hydraulic ratio tekinoroji, asi tekinoroji yayo iri munzvimbo yakakiyiwa.
Parizvino, iyo yakakura poda simbi yekugadzira zvidyarwa yakaunza yepamusoro yekugadzira hupfu uye mitsetse yekugadzira kubva kunze kwenyika, asi sumo yega haigone kugadzirisa dambudziko zvakanyanya.Naizvozvo, kusimudzira kwakazvimiririra kwepamusoro-tekinoroji yehupfu yekugadzira michina zvakare ndiyo yakakura maitiro ekusimudzira muindasitiri yehupfu.
Powder metallurgy forming process
Kuumba inhanho yakakosha muupfu metallurgy process.Chinangwa chekugadzira ndechekugadzira compact ine imwe chimiro, saizi, density uye simba.Compression molding ndiyo inonyanya kukosha yekugadzira nzira.
Iyo yekumanikidza yekuumba nzira ine yakapusa maitiro, yakanyanya kushanda zvakanaka, uye yakanakira kugadzira otomatiki.Zvisinei, kuparadzirwa kwekumanikidzwa kweiyi nzira hakuna kufanana, kuitira kuti kuwanda kwemuviri wakasvibirira hakusi yunifomu, uye kuputika kunowanzoitika, zvichiita kuti pave nekuonekwa kwezvinhu zvakashata.
a.Kufanana kwehuwandu hwekugovera kwekombiki: Nekuti iyo poda muviri inoyerera munzira dzese mushure mekusimbiswa mukufa, inokonzera kudzvanywa kwedivi perpendicular kumadziro efa.Kudzvinyirirwa kweparutivi kunokonzeresa kukweshera, izvo zvinokonzeresa kudonhedza kwakakura muhurefu hwekombikiti.
Matanho ekuvandudza: 1) Deredza kukakavara, shandisa mafuta ekuzora pamadziro emukati kana kushandisa mold ine rusvingo rwemukati rwakatsetseka;
2) Kudzvanya-nzira mbiri kunoshandiswa kuvandudza kusaenzana kwehuwandu hwekugovera kwegirinhi compacts;
3) Edza kudzikisa kureba-dhayamita reshiyo paunenge uchigadzira mold.
b.Demoulding kuperera: nekuda kwekuwedzera kwe elastic kwechikadzi mold panguva yekutsikirira, kana kudzvanywa kwabviswa, iyo compact inotadzisa iyo elastic contraction yemukadzi mold, uye compact inoiswa kune radial pressure, zvichiita kuti compact igamuchire reverse shear. kushushikana panguva yekudhirowa Mamwe mavara asina kusimba pane compact anogona kuparadzwa pasi peiyo yataurwa pamusoro pekuveura kushushikana.
Matanho ekuvandudza: Panyaya yechimiro, zvikamu zvinofanirwa kudzivirira dzakatetepa-madziro, dzakadzika uye dzakamanikana grooves, inopinza mipendero, madiki uye matete mabhosi uye mamwe maumbirwo zvakanyanya sezvinobvira.
Kubva pamapoinzi maviri ari pamusoro, tsananguro yakakasharara yekukanganisa kwechinhu chimwe chete mukuumbwa kwekudzora maitiro pamhando yechigadzirwa, asi mukushandisa zvinoshanda, zvakasiyana-siyana zvinopesvedzera zvinhu zvinowirirana.Munguva yekutsvagisa, zvinoonekwa kuti izvo zvinokanganisa kunaka kwechigadzirwa panguva imwechete ndezvi:
1. Mhedzisiro yekugadzira kudzvinyirira pahutano hwebillet: simba rekumanikidza rine simba rakananga pahuwandu.Iyo iripo yekudonha yekumanikidza inokonzeresa delamination uye peeling panguva yekudzvanya, uye makatsemuka aripo pakusangana kwekombuta mushure mekudhonzwa.
2. Mhedzisiro yekutsikirira kumhanya pamhando yekombiki: Munguva yehupfu compaction, iyo yekudzvanya inomhanyisa inokanganisa kubuda kwemhepo kubva mumapores pakati pehupfu, uye inobata zvakananga kufanana kweiyo compact density.Density musiyano we compact yakakura.Izvo zviri nyore kugadzira mitswe.
3. Mhedzisiro yekubata nguva pahutano hwekombiki: Panguva yekutsikirira, panofanira kunge kune nguva yakakodzera yekubata pasi pekunyanya kudzvinyirira, iyo inogona kuwedzera zvakanyanya kuwanda kwekombiki.
Iyo yakazara otomatiki poda metallurgy yekuumba midziyo ichangobva kugadzirwa naChengdu Zhengxi Hydraulic Equipment Manufacturing Co., Ltd. yakagadzirwa semudziyo mutsva wekupayona wepamba unobatanidza zvakanakira zvemichina yekutsikirira uye CNC servo hydraulic press.
Iyo inoyangarara template mhando inoumba mold base yemidziyo inogona kunyatso kudzora kuenderana kwechigadzirwa uye chiyero chakakodzera chechigadzirwa.Pahwaro hwekugutsa kugara uchidzvanya kudzvanya, iyo yakagadziriswa nzira yekutsikirira yemuchina wemuchina inowedzerwa, iyo haigone kungoshanda semuganhu asiwo seyakagadziriswa yekutsikirira nzira.Iyo kaviri-layer dziviriro yekutsikirira uye kudzvanya inovandudza zvakanyanya kunaka kwechigadzirwa uye kugona kugadzira.
