Kana vanhu vazhinji vachinzwa nhengo dzesimbi dzisiri dzemazuva ese, vanofananidza bhuraketi rakarebesa rakareba kupfuura zvamazuva ose, kana kuti pamwe giya rine mazino asinganzwisisike. Ndiyo yekutanga kusanzwisisa. Muchokwadi, inyika inotsanangurwa nekusavapo kwenhamba yekatalogi. Haisi yekungoita diki diki; ndezvekugadzira mhinduro inoshanda apo chikamu che-off-the-sherufu chinotadza, kazhinji pasi pekuranga mamiriro ekupisa, kushushikana, kana ngura. Dambudziko chairo harisi kungorigadzira chete — kuri kuita kuti rishande zvakavimbika kana pasina muenzaniso wekutevera.
Iyo Core yeIsiri-Yakajairwa: Iyo Maitiro, Kwete Chigadzirwa
Iwe haugone kupatsanura zvikamu izvi kubva kune process chain. Dhirowa inogara padhesiki rako - kazhinji dhizaini rakashata kubva kuna mainjiniya - uye mubvunzo wekutanga hausi isu tingachine izvi here? Ndezvei? Basa racho rinoraira zvese: zvinhu, nzira yekukanda, kushivirira kwekugadzira. Semuenzaniso, chepamusoro-tembiricha yevharuvhu yechirimwa chemakemikari haingori chikamu chesimbi isina tsvina. Iyo inotanga sekudyara kwekudyara mune nickel-based alloy kubata iyo corrosion, yobva yaita chaiyo CNC machining ekuisa chisimbiso, ichiteverwa nehunyanzvi hwekupisa kupisa. Chikamu chinoberekwa kubva mukutevedzana uku. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), nemakumi matatu emakore avo ekuunganidza ruzivo muzvose zviri zviviri kukanda uye kugadzira pasi pedenga rimwe chete, anowana izvi mukati. Unogona kuona maitiro avo pane yavo portal pa https://www.tsingtaocnc.com—ivo havangopi masevhisi; vanoratidza kugona kwakabatanidzwa. Ndiyo kiyi. Kurima kunze kwekukanda kune imwe chitoro uye machining kune imwe kune yechokwadi isiri-yakajairwa chikamu inzira yekunongedza zvigunwe kana chimwe chinhu chatadza.
Kusarudzwa kwezvinhu ndiko kunoitwa sarudzo huru dzekutanga, uye uko kukanganisa kunodhura. Mutengi akambosimbirira pa 316 isina tsvina yechikamu munzvimbo ine chlorine yakanyanya, ichitaura indasitiri chiyero. Isu takasundidzira kumashure, tichikurudzira duplex isina tsvina kana kunyange nickel alloy. Vakaenda ne316 kuchengetedza mutengo. Mwedzi mitanhatu gare gare, takanga tichigadzira imwe seti kubva pane alloy 20. Chidzidzo chacho? Non-standard kazhinji inoreva kuti nharaunda yekushanda haina-standard zvakare. Iwo mabhuku ezvinyorwa aunoona pane saiti seQSY's, achinyora zvese kubva kusimbi yakakandwa kusvika kune cobalt-based alloys, haingori menyu; ibhuku rekushandisa rekugadzirisa matambudziko aya asingataurwe ezvakatipoteredza.
The prototyping phase ine hutsinye. Ndiko uko dhizaini yetioretiki inosangana nezvokwadi yemuviri. Iwe unogona kunge uine yakanaka CAD modhi yeyakaomarara, yakatetepa-yakavakirwa turbine dzimba muInconel. Asi iyo shell mold casting process inogona kuwana ukobvu hwemadziro iwoyo pasina hurema? Ko iyo CNC yekushandisa inogona kusvika kune emukati chiteshi pasina kutsauka? Isu takave nemagadzirirwo aitaridzika zvakanaka asi zvaida kuti isu tigadzirise zvigadziriso zvechinyakare kuti tibate workpiece panguva yekugadzira, tichiwedzera 30% kune yenguva. Iyi ndiyo mari yakavanzika yebasa risiri-standard. Hakusi kusashanda; ndiwo mutero weR&D.
Kana Kukandira uye Machining Kunodhumhana (Chaizvoizvo)
Iyi ndiyo gritty tsanangudzo yakanyanya kupenya pamusoro: handoff kubva kune yakawanikwa kuenda kune muchina shopu. Kune chikamu chakajairwa, une fungidziro. Kune isiri-yakajairwa chikamu, iwe unosimbisa iyo spec kuburikidza nechinyorwa chekutanga. A shell mold casting, inozivikanwa nekunaka kwayo kwepamusoro uye kurongeka kwayo, ichiri nemhando dzakasiyana-siyana-shrinkage rates inosiyana zvishoma batch kune batch, kunyanya nearoyi akakosha. Iyo machinist inofanirwa kuziva kuti datum iri papi pakukanda mbishi. Zviri pamusoro here? Gomba rekukanda ndege? Isu takadzidza izvi nenzira yakaoma pakutanga nekugadzira kubva kune theoretical centerline pane pombi yekugara. Mhedzisiro yacho yaive chikamu chakagadzirwa zvakanaka chine madziro makubvu aisiyana ne1.5mm, zvichiita kuti isashande. Ikozvino, maitiro aya anosanganisira yekutanga dhizaini yekuongorora pane yekutanga kukanda, kunyatsoipenda nedhayi yebhuruu uye kunyora iwo chaiwo machining datums pairi. Iyo yakaderera-tech asi yakakosha.
CNC machining non-standard castings ndechimwe chikara. Iwe hausi kutanga neyunifomu billet. Iwe uri kunamatira pane yakaoma, kazhinji isina kuenzana, yekukanda. Yekutanga kucheka kwakakosha-inogadza ndege yako yereferenzi uye inowanzo ratidza subsurface porosity kana inclusions. Ndinorangarira giya hombe resimbi risina kuvharwa apo mudziyo waitaurisa pakupfuura kwekutanga. Takawana nzvimbo yakaoma, nzvimbo inotonhorera kubva pakukandira. Iyo yese machining sequence yaifanira kugadziridzwa panhunzi, inonoke mafeed uye kumhanya. Kana iwe uchingove chitoro chekugadzira machini uchitenga mbichana mbichana kubva kune wechitatu bato, kuwanikwa uku kunotungamira kune kumira uye mhosva. Kana iyo yekutanga uye chitoro chemuchina zvabatanidzwa, senge paQSY, mhinduro yacho inokurumidza. Iyo yekutanga timu inogona kugadzirisa tembiricha yekudurura kana mold coating yeinotevera batch, uye timu yekugadzira inogadzirisa chirongwa chavo. Inoshandura dambudziko kuita nzira yekuvandudza.
Ipapo kune iyo geometry inopa vanogadzira misoro misoro. Homwe dzemukati dzakadzika, dzakakanganiswa kucheka pakudyara-kanda turbine blades, weird compound angles. Haisi kungoita 5-axis kugona; iri pamusoro penzira yekushandisa. Kushandisa chishandiso chakareba kwazvo kunogona kukonzera kutsauka, kukanganisa kushivirira. Dzimwe nguva, iwe unofanirwa kugadzira uye kugadzira isiri-yakajairwa mudziyo wekushandisa kana tsika inofinha bar. Chinangwa hachisi chokungobvisa simbi; kuita kudaro usingaderedze kushushikana kana kudedera kunogona kukanganisa chikamu chekupedzisira kuita. Apa ndipo panotaurwa makumi matatu emakore ekumashure QSY haisi mutsara wekushambadzira-iraibhurari yemhinduro dzakapfuura dzekudhonza kubva kana dambudziko idzva, risinganzwisisike rasvika.
Iyo Alloy Dilemma: Yakakosha Nzira Inodhura, Asi Inodiwa
Vatengi vanopokana nekotesheni yechikamu checobalt-based alloy. Ndinozviwana. Mutengo wezvinhu pakirogiramu unoshamisa. Kururamiswa hakusi muzvinyorwa zvacho, asi mukukundikana kunodzivirira. Takashanda pane chimwe chikamu chepurasitiki extrusion die-ndiro yekupfeka. Yakajairwa simbi yesimbi yaizogara ingangoita mwedzi mitatu mune abrasive, inopisa polymer kuyerera. Isu takazviratidzira mucobalt-chromium alloy (Stellite type). Kugadzira kwaityisa; inoshanda-inoomesa ipapo, inoda kugadzika setups uye inopinza, yakasarudzika carbide maturusi. Asi ndiro iyoyo yakagara kwemwedzi inopfuura 18. Mari yekudzikira nguva yakadzikira mutengo wechikamu. Hunyanzvi pano hwakapetwa kaviri: kuziva nguva yekukurudzira aya akakosha maalloys, uye kuziva mashandire ekushanda nawo. Haisi kugona iwe unongotenga; unoivaka kuburikidza nemidziyo yakaparadzwa uye matepi akaputsika.
Kupisa kurapwa kweaya asiri-standard alloys post-machining ndeimwe nzvimbo yemugodhi. Kune simbi dzakawanda dzepamusoro-soro uye nickel alloys, kurapwa kwekupisa kunokosha pakuwana zvinhu zvinodiwa zvezvinhu-kuoma, kusimba kwesimba, kusununguka kwekunetseka. Asi kupisa kurapwa kunogona kukonzera kukanganisa. Kutevedzana kunokosha zvikuru. Iwe rough muchina, kupisa kubata, wozopedzisa muchina? Kana kuti unoita muchina zvizere, wobva wabata kupisa pane tembiricha yakaderera kuti uderedze warping? Hapana mhinduro yebhuku. Izvo zvinoenderana nechikamu chegeometry, maitiro eiyo alloy, uye yekupedzisira kushivirira. Takatozorasa mabhechi nekuti isu takanganisa kutevedzana kwechikamu chitsva, kunyangwe takamboshandisa alloy yakafanana. Imwe neimwe itsva geometry kuyedza kutsva.
Kukurukurirana: Chinonyanya Kukosha Chisina-Standard Tool
Kukundikana kukuru hakuwanzobva mukusagona kwehunyanzvi. Dzinobva mumikaha yekukurukurirana. Injiniya inogadzira basa. The foundry anofunga maererano castability. Iyo machinist inofunga maererano nekushandisa kwekushandisa uye kushivirira. Kana aya ari masangano akasiyana, unowana mutambo wefoni. Mufananidzo wacho unodudzirwa, wozodudzirwa zvakare. Chinyorwa chakakosha nezve yekuisa chisimbiso kupedzisa (taura, 0.8μm Ra) inogona kurasika kana iyo dhirowa ichidaidza chete mumanotsi akajairwa uye kwete pane chaiyo ficha callout. Isu zvino tinoomerera pakufona kwekutanga kune chero basa rakaoma risiri-standard, neinjiniya yemutengi, yedu yekutanga inotungamira, uye yedu machining inotungamira zvese pamutsetse. Isu tinoenda pamusoro pekudhirowa mutsara nemutsara, tichibvunza zvese. Iyi radius inofanirwa kunge iri 3mm, kana kuti ndeyekucheneswa chete? Tinogona here kuwedzera mudziyo diki wekushandisa pano? Hurukuro iyi yakakosha kudarika chero software yepamusoro.
Ichi ndicho chikonzero nhoroondo yekushanda kwekambani yakakosha. Ukaona kuti firm like QSY yanga iri mukukanda nekugadzira kweanopfuura makore makumi matatu, zvinoreva kuti vangangove vakaronga mafambiro avo ekufambisa iyi chaiyo mhando yenhaurirano yechirango. Zvakabikwa mukushanda kwavo. Webhusaiti yavo, https://www.tsingtaocnc.com, inoronga masevhisi avo akatenderedza iyo yakasanganiswa inopa-shell mold uye kudyara kwekudyara muCNC machining. Chimiro ichocho hachina tsaona; imhinduro kune zvakakosha zvinodiwa mu zvisiri-standard metal parts nyika: kubatanidzwa kusina musono kubva kusimbi yakanyungudutswa kusvika kune yapera chikamu.
Zvinyorwa ndiyo yekupedzisira, isina mbiru. Kune chikamu chakajairwa, unochitumira nechitupa chekuenderana. Kune isiri-yakajairwa chikamu, iwe kazhinji unoda yakazara dossier: zvinhu certs, kupisa kupisa machati, yekutanga-chinyorwa chekuongorora mishumo neCMM data, kunyangwe mafoto ematanho akakosha. Uku hakusi kutonga; zviri traceability. Kana chikamu ichocho chakavigwa mumusangano wemamiriyoni emadhora makore maviri kubva zvino uye mubvunzo unomuka, iyo dossier ndiyo chete kudzivirira. Kuvaka izvi muhurongwa hwekuyerera kubva pazuva rekutanga chiratidzo chemutengesi akura.
Pakupedzisira, Ndezve Kugadzirisa Dambudziko Risina Kunyorwa
Saka, chii chatiri kutaura nezvazvo neasiri-standard simbi zvikamu? Hatisi kungogadzira chinhu. Tiri kugadzira mhinduro kudambudziko risati ragadziriswa nenzira imwecheteyo. Kukosha hakusi mukirogiramu yesimbi yakatumirwa. Zviri muruzivo rwakadzamirwa-kunzwisiswa kwekuti nickel-based alloy inoyerera sei muinvestment mold, intuition yenzvimbo yekuisa riser kudzivirira shrinkage muyakaomeswa simbi yekukanda, ruzivo rwekusarudza coating chaiyo yechishandiso checarbide kugaya cobalt alloy.
Indima inosundwa nemisiyano, kwete mitemo. Chese chikamu chitsva ipurojekiti diki, ine njodzi dzayo uye curve yekudzidza. Makambani anogara kwenguva refu, ayo anovaka mukurumbira wemakore makumi matatu seQSY, anoita izvi nekugadzirisa maitiro avanoita izvi zvisiri izvo-kwete nekuita kuti zvive zvakaenzana, asi nekuva nehurongwa hwakasimba, hwekutaurirana, uye hunobatanidza hunogona kutora kusiyana uye huchiri kuendesa chikamu chinoshanda. Nguva inotevera paunoona isiri-yakajairwa RFQ, tarisa kumashure kwedhirowa. Ona kana mutengesi achibvunza nezve basa, zvakatipoteredza, kukundikana kwechikamu chekare. Ndicho chiratidzo chekuti vari mubhizinesi rekugadzirisa matambudziko, kwete kungocheka simbi.
