Paunonzwa 'powder metallurgy company', vanhu vazhinji vanobva vangofungidzira fekitori ichidzura makwenzi ari nyore, ane porous bronze kana magiya esimbi akachekwa. Ndiwo mufananidzo wekare, uye hazvina kukanganisa, asi zvakangofanana nekutsanangura resitorendi yemazuva ano senzvimbo inopa chikafu. Chokwadi chiri pavhu chakashata uye chinonakidza. Chinetso chaicho hachisi chokungotsikirira nekuisa hupfu; ndezvekubatanidza iyo yakakosha kugona mune yakazara mhinduro cheni, kunyanya kana iwe uchibata nepamusoro-kuita zvinhu. Ndakaona zvitoro zvakawanda zvakanamira mune isu tinogadzira PM zvikamu pfungwa, kukwikwidza chete pamutengo pakirogiramu, nepo kukosha chaiko kuchikwira kumusoro kunogadzira uye kudzika kusvika pakupedzisa. Ndiyo nzvimbo yakaoma kuva mairi.
Nyaya Ingori Pekutangira
Ngatitange tataura zvekushandisa, nekuti ndipo panowanzotangira nhaurirano. Isu tinoshanda zvakanyanya nesimbi, simbi, uye simbi isina hupfu, asi mutambo unochinja neakakosha alloys. Funga nickel-based kana cobalt-based superalloys kune yakakwirira-tembiricha maapplication. Heino musoro unoshanda: maitiro ekuyerera kweaya fancy alloy poda akasiyana zvachose kubva kune yako yakajairwa iron musanganiswa. Iwo anogona kuve akabatana, mashoma akasununguka-kuyerera, ayo anokanda kure otomatiki ekuzadza masisitimu akarongedzerwa zvinhu zvenguva dzose. Iwe haugone kungorasa hupfu hutsva muhopper uye kutarisira kuzara kwekuzadza kwakafanana. Zvinoda kudhonza shangu yekudyisa, dzimwe nguva kunyangwe iyo vibration frequency panguva yekuzadza. Iyo idiki dhata, asi kuikanganisa zvinoreva kusapindirana kwechikamu density usati watomborova sinter choto. Ini ndinorangarira imwe purojekiti yatakapedza mazuva maviri tichingori padanho rekuzadza rechikamu chitsva chenickel alloy, ichimhanya bvunzo compact uye kuyera density gradients. Zvaiita sekunge kunonoka, asi kusvetuka danho iroro kwaizove kwakavimbisa kutadza kwebatch gare gare.
Apa ndipo pave neyakakura yekugadzira zvinhu kumashure kune mukana wakakura. Oparesheni yedu yevabereki, Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), yanga iri mukugadzira nekugadzira kwemakumi emakore. Iyo yakadzama nhoroondo ine simbi dzakanyungudutswa sesimbi yakanyungudutswa uye yakakosha alloys inotipa maonero akasiyana padivi rehupfu. Hatisi kungotenga hupfu kubva kune mutengesi uye nekuidzvanya neupofu. Isu tinonzwisisa simbi kubva kumvura inokwira kumusoro, iyo inozivisa mabatiro atinoita iyo solid-state sintering. Semuenzaniso, kunzwisisa kupatsanurwa kwezvimwe zvinhu mukunyunguduka kunotibatsira kutarisira mabatiro avangaita panguva yekusagadzikana kwemamiriro ekunze mukupisa. Ihwaro hweruzivo rwakabatana.
Uye kupedza. Mwari, kupedza ndiko kune vakawanda upfu metallurgy mapurojekiti anorarama kana kufa. Iwe unogona sinter padyo-neti-chimiro chikamu zvinoyevedza, asi kana ichida chaiyo bore kana yakaoma yakaomeswa chimiro, uri kuenda kuCNC muchina. Kugadzira chikamu chakasimwa hakuna kufanana nekugadzira bhawa rakagadzirwa. Iyo porosity inogona kukanganisa maturusi, uye inogona kukanganisa magadzirirwo emidziyo. Takadzidza izvi nenzira yakaoma kare kare, tichipisa zvigayo pachinhu chaiita sesimbi yakapfava. Zvino, machining maprotocol ezvikamu zvePM akasiyana. Isu tinoshandisa akasiyana maturusi ejiometri, dzimwe nguva akasiyana anotonhorera, uye anogara akasiyana seti yekumhanya uye maverengero ekudya. Iyo nzira yakabatanidzwa. Icho chokwadi chekuti QSY ine yayo yakatsaurirwa CNC machining division (tsngtaocnc.com tsanangudzo dzezvavanokwanisa) hazvisi masanga; chinhu chinodiwa. Chikamu hachisati chapera kana chabva muchoto chinopisa. Inopedzwa kana yagadzirira kuungana kwevatengi.
Iyo Shell Mold Crossover: A Niche Yakakodzera Kuongorora
Izvi zvingaite sekusiyana, asi ndiitireiwo moyo murefu. Imwe nzvimbo isingatarisirwe zvakakwana ndiyo mharadzano pakati upfu metallurgy uye kukanda mari, kunyanya shell mold casting. Ivo vanowanzoonekwa senzira dzekukwikwidza, uye kune dzakawanda zvikamu, ndizvo. Asi pane synergy mune prototyping uye yakaderera-vhoriyamu, yakakwirira-yakaoma basa. Isu takashandisa PM kugadzira prototype tooling yeganda molds. Dzimwe nguva, mutengi anoda inoshanda bvunzo batch ye50 yakaoma giya dzimba, sechinyakare basa rekukanda. Kugadzira simbi yekuumba goko kunodhura zvakanyanya pavhoriyamu iyoyo. Isu takabudirira kushandisa simbi jekiseni molding (MIM, cousin of PM) kana kunyange yakakwirira-simba sintered simbi kugadzira epakati mabhokisi kana mold inoisa yegoko maitiro. Iyo yekumusoro kupedzisa haina kunyatsoita seyakagadzirwa simbi simbi yekuisa, asi ye50-100 inokandira, inosimudza uye inocheka nguva yekutungamira kubva kumwedzi kusvika kumavhiki.
Icho chinyengeri chaicho, kwete mhinduro yakajairika. Kuchovha bhasikoro kubva pakudurura simbi yakanyungudutswa mugoko rakavakirwa pasimbi yakanyungudutswa kunozopedzisira kwakonzera kuneta nekutsemuka. Asi pakugadzira mabhiriji kana prototyping, yakakosha zvakanyanya. Imhando iyi yekufunga kwepashure-kushandisa imwe nzira kugonesa imwe-inoparadzanisa chitoro chebasa kubva kune anopa mhinduro. Iwe unogona kuwana nyaya dzezvidzidzo pane iyi nzira yekuchinjisa mukume mune yakakura portfolio pa QSY's saiti. Inotaura kune huzivi hwekushanda huri pamusoro pekugadzirisa puzzles yekugadzira, kwete kungotengesa imwe nzira.
Iyo flip side iri kutonga zvinotarisirwa nevatengi. Paunoronga nzira yakadai yakasanganiswa, iwe unofanirwa kuve wakajeka zvine hutsinye pamusoro pezvipimo. Hongu, tinogona kukuwanira zvikamu zvinoedzwa mumavhiki matatu tichishandisa nzira iyi, asi iyo tooling ichaderedza mushure memazuva makumi masere, uye kushata kwepamusoro pachikamu chekupedzisira chichava Ra ye6.3, kwete 3.2. Zvinotenderwa here pachikamu chako chekusimbisa? Iyo yechokwadi, yepamberi nhaurirano, yakavakirwa mune inoshanda data kubva kune yakapfuura kuyedza (kusanganisira yakakundikana apo isu takavimbisa zvakanyanya pamusoro pehupenyu hwekushandisa), inovaka kuvimbana kupfuura chero bhurocha rinopenya.
Kana Zvakanaka Zvakakwana Zvisina: Musungo Wokushivirira
Tolerances mukati upfu metallurgy inguva dzose nhaurirano nefizikisi. Iyo sintering process inosanganisira shrinkage, uye iyo shrinkage haisi nguva dzose isotropic yakakwana. Izvo zvinoenderana nechikamu chejometri, density gradients kubva mukudhinda, uye tembiricha yevira. Tinogona kuitevedzera, asi panogara paine musiyano. Kune akawanda maumbirwo ezvikamu, akajairwa PM kushivirira kwakanaka. Asi isu tiri kuwedzera kukumbirwa kuti tigadzire zvikamu zvinokwikwidza nemidziyo yemuchina pakugadzikana kwedimensional.
Izvi zvinokusundira mumabasa echipiri senge saizi (kudzvanyazve chikamu chakasimwa mufa) kana CNC machining. Yese yechipiri op inowedzera mutengo. Saka iro chairo basa reinjiniya riri mudhizaini-ye-kugadzira (DFM) nhanho. Tinogona here kugadzirisa iyi undercut kuti ibvise? Tinogona here kugadzirisa ukuru hwemadziro kuti tikurudzire yunifomu compaction uye nekudaro kuwedzera yunifomu shrinkage? Dzimwe nguva, mhinduro ndeye kwete, uye iwe unofanirwa kuronga bhajeti yekugadzira. Chinokosha kuita hurukuro iyoyo nemugadziri asati amborairwa. Ndakagara mumisangano umo takadhirowazve chikamu chemuchinjiko pabhodhi chena kuratidza kuti shanduko ye 1mm radius inogona kuchengetedza 30% pamutengo wechikamu nekugonesa kuyerera kuri nyore-uye-sinter. Ndiyo kukosha-kuwedzera.
Inosungirirawo kusarudzo yezvinhu. A low-alloy simbi poda inogona kunyura kune rimwe bhendi rekushivirira. Stainless simbi poda, ine akasiyana shrinkage maitiro, ingangoda akasiyana zvachose muripo wekushandisa. Iwe unofanirwa kuziva izvi kubva munhoroondo data. Isu tinochengetedza raibhurari ye shrinkage zvinhu kune zvakajairika zvinhu uye geometry mhuri. Haisi chiyero chakaburitswa; igwaro rekugara remukati, rakagadziridzwa nechero chigadzirwa chinomhanya. Ndirwo rudzi rwechinyararire, ruzivo rwechokwadi powder metallurgy kambani inounganidza.
Iyo Supply Chain Chinhu Chinoputsika
Hapana anotaura nezve supply chain kusvika yadambuka. Nokuti a upfu metallurgy kushanda, hazvisi zvekungowana hupfu hwesimbi. Izvo ndezvekuwana iyo chaiyo yakawanda, ine inowirirana particle size kugovera uye chemistry. Batch yehupfu ine avhareji akasiyana avhareji saizi inogona kushandura density yekuzadza mufa, ichishandura zviyero zvekupedzisira zvakatsikirirwa. Isu takatofanira kuvharisa zvinhu zvese zvakatakurwa nekuti macert aisaenderana nenhoroondo yedu yekutanga chikamu chakareba. Ihope huru.
Zvadaro pane tooling. Iyo inofa uye zvibhakera. Iwo akagadzirwa kubva kuhunyanzvi, asingapfeki simbi yemidziyo. Chikamu chakaoma chinogona kunge chine mazinga akawanda ekufa ane akati wandei anofamba zvibhakera. Kana imwe punch ikatsemuka kana kupfeka nguva isati yakwana, mutsara wese wekugadzira unomira. Nguva yekutungamira yemidziyo mitsva yesimbi inogona kuve mavhiki gumi nemaviri. Saka iwe unodzidza kuchengetedza yakakosha hesita yeasara punch matipi, ekutungamira tsvimbo, uye kunyange ese ekufa seti yeakakwira-vhoriyamu zvikamu. Imari yakafa yakagara pasherufu, asi inshuwarisi. Ichi chaicho chekushanda hachimboonekwe mukushambadza blurb nezve advanced PM kugona, asi ndizvo zvinoita kuti mwenje urambe uchibatidzwa. Kambani ine makore makumi matatu emusana, seboka kumashure QSY, akararama mukati mematambudziko akawanda ekupa uye ane hekatori uye hukama hwevatengesi kuti vavhare izvo zvinokatyamadza. Chinhu chisingabatike asi chakakosha.
Uye haisi kungopa muviri chete. Kupa ruzivo. Kana mutori wenhau akasiya basa, anotora pfungwa yekuti kana ruzha rwekutsikiswa rwadzimwa kana kuti kushanduka kudiki pane chikamu chakadzimwa zvinorevei. Kubata izvo zvinenge zvisingaite. Isu tinoedza nemaitiro ekutarisa uye sensor data, asi mamwe mafoni ekutonga anozvarwa kubva kumakumi emakore ekutarisa zvikamu. Iro layer yemunhu mudura rekutengesa ndiro rakanyanya kusimba pane ese.
Kutarisa Mberi: Haisi Chikamu Chete, Iri Basa
Saka izvi zvinosiya papi a powder metallurgy kambani nhasi? Iwo anozobudirira ari kubva pakuva vatengesi vechikamu. Chikamu inzira yekuzadzisa chinangwa. Mutengi haadi sintered sprocket; vanoda yakavimbika, inodhura-inoshanda rotational drive interface. Tinogona here kupa iyo sprocket, iyo yekuisa shaft yakagadzirwa kuburikidza neCNC machining, uye kunyangwe gungano? Tinogona here kupa zano pachirongwa chekuzora zvichibva pane porosity yezvinhu zvedu? Ndiko kuchinja.
Zvinoda kubatanidzwa kwakadzama kwemaitiro, chaizvo mhando inoratidzwa muchimiro chekambani inogara upfu metallurgy, kuisa mari, kuumba shell, uye CNC machining pasi peimwe amburera inoshanda. Chinangwa ndechekuve neyakawanda yekukosha rwizi. Inobvumira kutendeseka kwehutsinye mukusarudza nzira zvakare. Dzimwe nguva, mushure mekuongorora kweDFM, tinogona kukurudzira kuti chikamu chakaitwa parizvino kuburikidza nePM chingashandiswe zvirinani sediki diki rekukanda kubva kune yedu goko rekuumbwa mold line, kana kunyange machined billet, uye tinogona kuzviita. Iko hakuna kukurudzira kumanikidza-kukodzera iyo PM maitiro paasiri ake.
Pakupedzisira, zvinouya pakugadzirisa matambudziko, kwete kungoita zvidimbu. Hupfu ndiwo mavambo enyaya, kwete magumo. Basa chairo—iro rinonakidza, rinokangaidza, uye dzimwe nguva rinogutsa zvikuru—rinoitika mukunzwisisa kuti chidimbu chakasiiwa chinopindirana sei nenyika: kuti chinopera sei, chinounganidzwa sei, mapfekero acho mubasa. Ndiwo mafungiro. Zvishoma pakuve a powder metallurgy kambani uye nezvimwe pamusoro pekuve mupi wekugadzira zvigadziriso ane hupfu simbi sechinhu chakakosha, chinonzwisiswa zvakanaka mukiti yayo. Uye iyo, ndinofunga, ndiyo chete nzira inoenderera mberi.
