Xa iinjineli zichaza a inkonzo yokuphosa kwi-high-pressure hydraulic valves okanye iindawo zempompo ze-cobalt-alloy, azikho nje uku-odola isinyithi-zibheja ngokuzinza kwe-dimensional phantsi kwemithwalo ye-300-bar, ukunyaniseka kwe-microstructure emva kokunyanga ubushushu, kunye ne-zero batch-to-batch drift in corrosion resistance. Siye sabona abathengi belibazisa ukuqinisekiswa kweprototype kwiiveki ze-11-kungekhona ngenxa yeziphene zoyilo, kodwa ngenxa yokuba iqabane labo lokuphosa alikwazanga ukubamba ± 0.05 mm kwi-AMS 5387 nozzle bore. Ayingomba womatshini lowo. yi inkonzo yokuphosa ingxaki yokukhula.
Kutheni “UkuFunyaniswa Kwetalente Okuthembekileyo” sisikweko esingalunganga—kwaye eyona nto isebenzayo
“Ukufunyanwa kwetalente” kukwimveliso yeefilim—hayi ukufunyanwa kwecandelo lemizi-mveliso. Ekuphoseni ngokuchanekileyo, ukuthembeka kuthetha ukuziphatha okuqikelelweyo okuqikelelwayo kubumba lwesanti yezindlu ze-T800 zealloy, hayi izinto ezifunyanisiweyo. Kuthetha ukuqinisekisa yonke i-cobalt-nickel ingot ngokuchasene neengxelo zovavanyo lwe-mill ngaphambi kokugalelwa-ukungathembi izatifikethi zomthengisi ngexabiso lobuso. Kuthetha ukubamba i-0.12% yokuphambuka kwekhabhoni kwisitokhwe sentsimbi engenayo ngaphambi kokuba ibe yi-brittle fracture kwi-piston pump cylinder housing.
Siphicothe ngaphezu kwe-40 foundries kulo lonke elase-Asiya naseMpuma Yurophu ukususela ngo-2019. Umahluko ongaguqukiyo? Ukudityaniswa ngokuthe nkqo-kungekhona nje "ukuphosa + ukwenziwa," kodwa kwabelwana ngokutolika kwe-GD&T phakathi kwabayili bepateni kunye nabadwelisi benkqubo be-CNC. Omnye umxhasi wathumela imizobo efanayo kubathengisi abathathu: ezimbini zicatshulwe ngokwahlukeneyo ukuze zenziwe kunye nokugqiba-machining; eyesithathu imephu yedatha ebalulekileyo ukusuka kumgodi wokungunda ukuya kwingxelo yokugqibela yeCMM. Kuphela loo mthengisi wahambisa iinxalenye zenqaku lokuqala eziphumelele uvavanyo loxinzelelo olusebenzayo ngosuku lokuqala.
Ayikokufunyanwa kwetalente leyo. Yinkqubo yobunini.
Izinto ezine ezingaxoxisiyo kwiMission-Critical Casting (iXhaswa yiDatha yokuFaila okukwenyani)
Iqela lethu lentsimi lilandelela izizathu ezisisiseko zokulahlwa okukhatywayo kuzo zonke iiprojekthi ezisebenzayo eziyi-127. Iimowudi ezine zokusilela zilawula-nganye idityaniswe ngokuthe ngqo kwindlela a inkonzo yokuphosa ilwakha inkqubo yayo:
- I-Microshrinkage kwimizimba yevalvu ephezulu: Kwenzeka xa i-gradients ye-thermal idlula i-12 ° C / mm ngexesha lokuqiniswa. Ukulungiswa kuphela ngexesha langempela le-thermocouple esweni kwi-mold cavities-kungekhona ukuhlolwa kwe-post-pour.
- I-GD&T ikhukuliseka phakathi kwe-as-cast kunye nelizwe eligqityiweyo: Ibangelwa kukungahambelani kwemijikelo yokunciphisa uxinzelelo. Silinganisa uxinzelelo olushiyekileyo lwangaphambili kunye nasemva kwe-annealing usebenzisa i-XRD; abathengi abatsiba oku bona i-0.08-0.15 mm warpage kwi-300-mm yezindlu ze-cylinder.
- Amaqela okubandakanywa kwi-cobalt alloys: Ibangelwa lukhukuliseko lweladle refractory. Ukuqinisekiswa nge-ASTM E45 Uhlobo lokulinganisa lokubandakanywa-kungekhona nje ukujonga okubonakalayo.
- I-Dimensional scatter in non-standard winch shaft rollers: Iziphumo ezisuka kushicilelo olungundoqo olungaqiniswanga. Isonjululwe kuphela ngolungelelwaniso lwe-optical yeebhokisi ezingundoqo phambi kokutshintsha ngalunye.
Akukho nanye kwezi "yimiba yomgangatho." Ziye zifakwe kwi-architecture yenkqubo yokuphosa. Awukwazi ukuhlola indlela yakho yokuphuma kubo.
I-Advanteji yeHybrid: Apho iCasting iyeka khona kunye nokuMachining kuqala
Ukuphosa ayisonyathelo elizimeleyo-sisiseko sento elandelayo. Umzimba wevalve yoxinzelelo ofakwe kwi-iron ductile unokufuna imisebenzi ye-CNC ehlukeneyo eli-17: ukugrunjwa komngxuma onzulu kwiipaseji zokulinga, ukugaya i-contour yendawo yokutywina, intambo ejikelezayo yokudityaniswa kwetorque ephezulu. Kodwa ukuba ubukhulu bodonga lwe-as-cast buyahluka nge-± 1.2 mm, ubomi besixhobo buyehla nge-40%, kwaye ukugqiba umphezulu ebusweni bokutywinwa akuphindi kuphindeke.
Yiyo loo nto ukuthembeka kokwenyani kufuna ulawulo oluxubileyo. Kwiziko lethu le-Qingdao, injineli efanayo iqinisekisa zombini iipateni zokuphosa i-wax kunye nenkqubo ye-5-axis machining. Sisebenzisa i-laser-scanned as-cast data to auto-adjust to toolpaths-cut cut cycle time by 22% kwi-AMS 5387 iipump parts ngelixa ubambe i-Ra ≤0.4 µm kwiindawo ezibalulekileyo zokutywinwa. Lo ayingomlingo wesoftware. Luqeqesho olusebenzayo: ii-metallurgists zabelana ngeefayile zokulinganisa ukuqinisa kunye nama-machinists; Amagcisa e-QC alungelelanisa i-CMM probes esebenzisa i-master gages efanayo esetyenziswa kuhlolo lwe-Foundry.
Ngaphandle kwaloo loop, ulawula imingcipheko emibini eyahlukileyo-hayi isisombululo esinye esidibeneyo.
Yintoni "enokuthenjwa" eneneni ithetha ngeProjekthi yakho elandelayo
Ukuthembeka akulobango lokuthengisa. Inokulinganiswa: i-99.2% isivuno sokuqala kwi-cobalt-alloy nozzles, i-100% yokulandelela izinto eziphathekayo phantsi kwenani lobushushu kunye nelogi enyibilikayo, kunye nokuthobela ukuhanjiswa ngaphakathi kwe-± 3 iintsuku kwi-86% yee-odolo zomthamo ophakathi (idatha ye-2023). Kuthetha ukuba uphononongo lwakho lomzobo lubandakanya ingxelo efana ne "Hambisa i-datum B 0.3 mm ngaphakathi-oku kuthintela ukuphazamiseka kwe-0.1 mm kwinkqubo yokungena" endaweni yokuthi "Siza kuzama konke okusemandleni ethu."
Ukuba iodolo yakho elandelayo ibandakanya ukugalelwa kwentsimbi kumhlaba owenziwe ngeoyile, izindlu zentsimbi engenasici kwiimpompo zangaphantsi kwamanzi, okanye amacandelo angekho mgangathweni e-T800 afuna ukuthotyelwa kwe-ASME BPVC yeCandelo II, cela inkonzo yokuphosa imibuzo emithathu: Ngaba ungandibonisa iingxelo zeCMM ezintathu zokugqibela zenxalenye ehambelana nokupakishwa kwam kokunyamezela okubalulekileyo? Ngubani umnini weshedyuli yokulondolozwa kwepatheni-kwaye kukangaphi ulungelelwaniso lwebhokisi olungundoqo luqinisekiswa? Lugqibele nini uphicotho lwakho lwangaphakathi ngokuchasene ne-ISO 9001:2015 Igatya 8.5.1 (Imveliso nobonelelo lweenkonzo)?
Iimpendulo ziya kukuxelela ngaphezu kwayo nayiphi na incwadana enemifanekiso.
