Iyo wunvise 'powder metallurgy company', abantu benshi bahita bashushanya uruganda ruvunagura ibiti byoroshye, bikozwe mu muringa cyangwa wenda ibyuma byacumuye. Ngiyo shusho ya kera, kandi ntabwo ari bibi, ariko ni nko gusobanura resitora igezweho nkahantu hatanga ibiryo. Ukuri kwisi ni akajagari kandi karashimishije. Ikibazo nyacyo ntabwo ari ugukanda gusa no kumena ifu; nibijyanye no guhuza ubwo bushobozi bwibanze murwego rwuzuye rwo gukemura, cyane cyane iyo ukorana nibikoresho bikora neza. Nabonye amaduka menshi afatirwa mubitekerezo dukora ibice bya PM imitekerereze, irushanwa gusa kubiciro kuri kilo, mugihe agaciro nyako kwimuka hejuru kugishushanyo no kumanuka kugeza kurangiza. Aho ni ahantu hakomeye kuba.
Ibikoresho ni Intangiriro
Reka tubanze tuvuge ibikoresho, kuko niho ikiganiro gitangirira. Dukora cyane hamwe nicyuma, ibyuma, hamwe nifu yicyuma, ariko umukino urahinduka hamwe na alloys. Tekereza nikel-ishingiye cyangwa cobalt ishingiye kuri superalloys kubushyuhe bwo hejuru. Dore ububabare bufatika bwumutwe: ibiranga urujya n'uruza rw'ifu nziza biratandukanye rwose no kuvanga ibyuma bisanzwe. Birashobora kuba byinshi, bidafite ubuntu-bitemba, bita sisitemu yo kuzuza byikora byateganijwe kubintu bisanzwe. Ntushobora guta ifu nshya muri hopper hanyuma utegereze ubwinshi bwuzuye. Bisaba guhindura inkweto zo kugaburira, rimwe na rimwe ndetse ninshuro yinyeganyeza mugihe cyo kuzuza. Nibintu bito, ariko kubyumva nabi bivuze ubucucike bwibice bidahuye mbere yuko ukubita itanura rya sinter. Ndibuka umushinga umwe aho twamaranye iminsi ibiri gusa kuri stade yuzuye kubintu bishya bya nikel alloy, gukora ibizamini no gupima gradients. Byumvaga ari ugutinda, ariko gusimbuka iyo ntambwe byari kwemeza gutsindwa nyuma.
Aha niho kugira ibikoresho byagutse byo gutunganya ibintu ninyungu nini. Igikorwa c'ababyeyi, Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), amaze imyaka mirongo akora muri casting no gutunganya. Ayo mateka yimbitse hamwe nicyuma gishongeshejwe nkicyuma hamwe nuduseke twihariye biduha imyumvire itandukanye kuruhande rwifu. Ntabwo tugura ifu gusa kubitanga no kuyikanda buhumyi. Twunvise metallurgie duhereye kumazi hejuru, itanga uburyo dukemura ikibazo gikomeye-cyicyaha. Kurugero, gusobanukirwa imyumvire yo gutandukanya ibintu bimwe na bimwe bishonga bidufasha kumenya uko bashobora kwitwara mugihe cyo gukwirakwizwa-gukomeye-gucumura. Nubumenyi buhujwe.
Kandi kurangiza. Mana, kurangiza niho benshi ifu ya metallurgie imishinga ibaho cyangwa ipfa. Urashobora gucumura hafi-net-shusho igice cyiza, ariko niba gikeneye bore neza cyangwa ibintu bigoye cyane, ugiye kumashini ya CNC. Gukora igice cyacumuye ntabwo ari nko gutunganya akabari. Umubyigano urashobora kwangiza ibikoresho, kandi birashobora kugira ingaruka kubintu byogosha. Ibi twabyize inzira igoye hakiri kare, gutwika urusyo rwanyuma kubintu bisa nicyuma cyoroshye. Noneho, protocole yacu yo gutunganya ibice bya PM iratandukanye. Dukoresha ibikoresho bitandukanye bya geometrike, rimwe na rimwe ibicurane bitandukanye, kandi burigihe bitandukanye bitandukanye byihuta no kubara ibiryo. Ninzira ihuriweho. Kuba QSY ifite ishami ryayo ryabigenewe rya CNC (tsingtaocnc.com burambuye ubushobozi bwabo) ntabwo ari impanuka; ni ngombwa. Igice nticyarangiye iyo gisize itanura ryacumuye. Byarangiye iyo byiteguye kumurongo witeranirizo ryabakiriya.
Igikonoshwa Mold Crossover: Niche Ikwiye Gushakisha
Ibi birasa nkaho bitandukaniye, ariko munyihanganire. Umwanya umwe utabona ibitekerezo bihagije ni ihuriro hagati ifu ya metallurgie no gushora imari, byumwihariko shell mold casting. Bakunze kugaragara nkibikorwa byo guhatana, kandi kubice byinshi, ni. Ariko hariho ubufatanye muri prototyping hamwe nubunini buke, akazi gakomeye. Twakoresheje PM kugirango dukore prototype igikoresho cya shell mold. Rimwe na rimwe, umukiriya akenera icyiciro cyibizamini byamazu 50 yububiko bukomeye, bisanzwe akazi ka casting. Gukora icyuma cyo kubumba ibishishwa birahenze cyane kubijwi. Twagize amahirwe yo gukoresha icyuma gitera inshinge (MIM, mubyara wa PM) cyangwa se imbaraga zikomeye zo gucumura ibyuma kugirango tubyare udusanduku twibanze cyangwa insimburangingo yo gutunganya igikonoshwa. Kurangiza hejuru ntabwo aribyiza cyane nkibikoresho byabigenewe byinjizwamo ibyuma, ariko kuri 50-100, birafata kandi bigabanya igihe cyo kuyobora kuva kumezi kugeza kumyumweru.
Nuburiganya bwihariye, ntabwo ari igisubizo rusange. Amagare yubushyuhe bwo gusuka avuye gusuka ibyuma bishongeshejwe mugikonoshwa cyubatswe ku cyuma cyacumuye amaherezo bizatera umunaniro no gucika. Ariko kubyara ikiraro cyangwa prototyping, bifite agaciro kadasanzwe. Ubu ni bwo buryo bwo gutekereza kuruhande - ukoresheje inzira imwe kugirango ushoboze indi - itandukanya iduka ryakazi nuwitanga ibisubizo. Urashobora kubona ubushakashatsi bwibibazo kuri ubu buryo bwambukiranya imipaka mugari mugari kuri QSY'Urubuga. Ivuga kuri filozofiya ikora yerekeye gukemura puzzle yo gukora, ntabwo igurisha inzira imwe gusa.
Impande zinyuranye zirimo gucunga ibyo abakiriya bategereje. Mugihe utanze ubwo buryo bwo kuvanga, ugomba kuba usobanutse muburyo bugarukira. Nibyo, turashobora kubona ibice byageragejwe mubyumweru bitatu dukoresheje ubu buryo, ariko ibikoresho bizagenda byangirika nyuma yizunguruka zigera kuri 80, kandi ubukana bwubuso ku gice cya nyuma buzaba Ra ya 6.3, ntabwo 3.2. Ese ibyo biremewe icyiciro cyawe cyo kwemeza? Icyo kiganiro cyinyangamugayo, cyambere, gishingiye kumibare ifatika uhereye kubigeragezo byashize (harimo ibyananiranye aho twasezeranije cyane kubuzima bwibikoresho), byubaka ikizere kuruta agatabo kose.
Iyo Ibyiza Bihagije Atari: Umutego wo kwihanganira
Ubworoherane muri ifu ya metallurgie ni imishyikirano ihoraho hamwe na fiziki. Inzira yo gucumura ikubiyemo kugabanuka, kandi kugabanuka ntabwo buri gihe ari isotropic. Biterwa nigice cya geometrie, gradients ziva mubinyamakuru, hamwe nubushyuhe bwitanura. Turashobora kuyigana, ariko burigihe hariho itandukaniro. Kubice byinshi byubaka, kwihanganira PM bisanzwe ni byiza. Ariko turasabwa cyane kubyara ibice bihanganye nibikoresho byakorewe imashini ihagaze neza.
Ibi bigusunika mubikorwa bya kabiri nko gupima (ongera ukande igice cyacumuye mugupfa) cyangwa imashini ya CNC. Buri cyiciro cya kabiri op yongeraho ikiguzi. Igikorwa cyubwubatsi rero kiri mubishushanyo-byo-gukora (DFM). Turashobora guhindura iyi undercut kugirango tuyiveho? Turashobora guhindura uburebure bwurukuta kugirango duteze imbere guhuza hamwe bityo kugabanuka kimwe? Rimwe na rimwe, igisubizo ni oya, kandi ugomba gukoresha bije yo gutunganya. Urufunguzo ni ukugira icyo kiganiro nuwashushanyije mbere yuko ifu itumizwa. Nicaye mumateraniro aho twongeye gushushanya igice cyambukiranya ikibaho cyera kugirango nerekane uburyo impinduka ya radiyo 1mm ishobora kuzigama 30% kubiciro byigiciro mugushoboza gukanda-na-sinter. Nibyo byongerewe agaciro.
Ihuza kandi no guhitamo ibintu. Ifu yoroheje-ifu yicyuma irashobora gucengera kumurongo runaka wihanganira. Ifu idafite ibyuma, hamwe nimyitwarire itandukanye yo kugabanuka, irashobora gusaba indishyi zitandukanye. Ugomba kumenya ibi uhereye kumateka yamateka. Tugumana isomero ryibintu bigabanuka kumiryango yacu isanzwe hamwe na geometrie. Ntabwo aribisanzwe byatangajwe; ni inyandiko nzima imbere, ivugururwa nibikorwa byose bikora. Ubwo ni ubwoko bwa tacit, ubumenyi bufatika ifu ya metallurgie irundanya.
Urunigi rwo gutanga ni ikintu cyoroshye
Ntamuntu uvuga ibijyanye no gutanga kugeza igihe bimenetse. Kuri a ifu ya metallurgie imikorere, ntabwo ari ukubona ifu yicyuma gusa. Nukubona ubufindo bukwiye, hamwe ningero zingana zingana zo gukwirakwiza na chimie. Igice cya poro gifite ubunini butandukanye buringaniye buringaniye burashobora guhindura ubwuzure bwuzuye mugupfa, bigahindura ibipimo byanyuma. Tugomba gushyira mu kato ibyoherejwe byose kubera ko cert zidahuye n'amateka yacu y'amateka igice kinini. Ninzozi mbi.
Noneho hariho ibikoresho. Gupfa no gukubita. Byakozwe mubikoresho byabugenewe, birinda kwambara ibyuma. Igice kitoroshye gishobora kugira urwego rwinshi rupfa gukubitwa inshuro nyinshi. Niba igikuba kimwe cyacitse cyangwa cyambaye imburagihe, umurongo wose wo gukora urahagarara. Igihe cyambere kubikoresho bishya byibyuma birashobora kuba ibyumweru 12+. Wowe rero wiga kubika ibintu byingenzi byerekana inama zidasanzwe, kuyobora inkoni, ndetse no gupfa byose kubice byinshi. Numurwa mukuru wapfuye wicaye ku isanduku, ariko ni ubwishingizi. Uku gukora ntigushobora kugaragara muburyo bwo kwamamaza kubyerekeye ubushobozi bwa PM, ariko nibyo bituma amatara yaka. Isosiyete ifite imyaka 30 yumugongo, nkitsinda ryinyuma QSY, yabayeho mubibazo byinshi byo gutanga kandi afite ibarura hamwe nabatanga isoko kugirango bagabanye ayo mahano. Numutungo udasanzwe ariko ukomeye.
Kandi ntabwo ari ibintu bifatika gusa. Ni ubumenyi. Iyo umukoresha w'itangazamakuru w'inararibonye asezeye, ajyana na instinzi yo mugihe ijwi ryabanyamakuru rizimye cyangwa icyo ibara ritoya ku gice cyasohotse bivuze. Gufata ibyo ntibishoboka. Turagerageza kurutonde rwibikorwa hamwe namakuru ya sensor, ariko guhamagarwa kwurubanza kuvuka kuva mumyaka mirongo tureba ibice. Urwo rwego rwabantu murwego rwo gutanga ni rworoshye cyane muri byose.
Kureba imbere: Ntabwo ari igice gusa, ni imikorere
Noneho aho ibi bisiga a ifu ya metallurgie Uyu munsi? Izatera imbere zirimo kugenda kure yo gutanga ibice gusa. Igice nuburyo bwo kurangiza. Umukiriya ntashaka isoko yacumuye; bakeneye interineti yizewe, ihendutse-yimodoka. Turashobora gutanga isoko, uruzitiro rwo guhuza rwakozwe hakoreshejwe imashini ya CNC, ndetse ninteko? Turashobora gutanga inama kuri gahunda yo gusiga dushingiye kubintu byiza byibikoresho byacu? Ngiyo guhinduka.
Birasaba guhuza ibikorwa byimbitse, muburyo bugaragara muburyo bwa sosiyete ibamo ifu ya metallurgie, gushora imari, gushushanya ibiceri, no gutunganya CNC munsi yumutaka umwe ukora. Intego ni ugutunga byinshi byagaciro. Iremera ubunyangamugayo bukabije muguhitamo inzira. Rimwe na rimwe, nyuma yisuzuma rya DFM, turashobora gusaba ko igice cyakozwe binyuze kuri PM cyarushaho kuba cyiza nko guterwa kuva kumurongo wibishushanyo mbonera, cyangwa na fagitire yakozwe, kandi dushobora kubikora. Nta mpanvu yo guhatira guhuza gahunda ya PM aho itari.
Kurangiza, biza gukemura ibibazo, ntabwo gukora ibice gusa. Ifu nintangiriro yinkuru, ntabwo iherezo. Igikorwa nyacyo - umurimo ushimishije, utesha umutwe, kandi rimwe na rimwe ushimishije cyane - bibaho mugusobanukirwa uburyo icyo gice cyacumuye gikorana nisi: uko kirangira, uko giterana, uko cyambara muri serivisi. Iyo niyo mitekerereze. Ntabwo ari bike kubyerekeye kuba a ifu ya metallurgie nibindi byinshi byo kuba ibisubizo bitanga ibisubizo bifite ifu ya metallurgie nkigikoresho cyibanze, cyunvikana neza mubikoresho byacyo. Kandi ibyo, ngira ngo, niyo nzira yonyine irambye igana imbere.
