Xa iinjineli zichaza ukuphosa ngentsimbi ngoomatshini kwiivalvu ze-hydraulic, i-pump housings, okanye i-winch shafts, abagcini nje uku-odola inxalenye-bazimisele ukuzinza kwe-dimensional phantsi koxinzelelo lwe-350-bar, ukunyaniseka kwe-microstructural emva kokuhamba ngebhayisikile eshushu, kunye nokugqiba umphezulu ochasayo ukuguga kwe-abrasive kwimijelo yeoli egcwele isanti. Siye sabona iiprojekthi ezininzi ziphazamiseka xa ababoneleli bephatha intsimbi njengenkqubo yorhwebo-emva koko banikezela ngomatshini kwivenkile yomntu wesithathu enokutolikwa ngendlela engafanelekanga kwe-GD&T, iirekhodi zokunyanga ubushushu obungahambelaniyo, okanye akukho mkhondo we-ASTM A48 Class 350 batches.
Kutheni ukuphosa kwentsimbi koomatshini kusilela-kwaye yintoni kanye esebenzayo
Ukuphoswa kwentsimbi kuphela akuqinisekisi ukusebenza. Iiflake ze-iron engwevu zegraphite zibonelela ngokufumisa kodwa zinciphisa ukomelela; I-ductile iron's spheroidal graphite iphucula ukuqina kodwa ifuna ulawulo oluchanekileyo lwe-nodularization ngexesha lokugalela. Yongeza ubuchwephesha be-CNC-kwaye wazisa ii-vectors ezintsha ezingaphumeleliyo: ukuphambuka koxinzelelo olushiyekileyo ukusuka ekupholiseni okungalinganiyo, amanqaku encoko kwiibhore zesilinda ezinodonga olucekeceke, okanye ubulukhuni obudala ukunxitywa kwesixhobo kwangaphambi kwexesha ngexesha lokugqitywa kokugqibela.
Sakhe saphinda salungisa ibhetshi yezindlu zempompo yepiston ngenxa yokuba isiseko sasebenzisa inkunkuma ebuyiselweyo ngaphandle kokuqinisekiswa okubonakalayo. Ukwahluka okubangelwa yi-silicon kutshintshe ubulukhuni ukusuka kwi-220-240 HB ukuya kwi-265 HB kwimimandla yendawo-ngokwaneleyo ukuphambuka kwi-0.012 mm ngexesha lokugqiba ukudika. Yiyo loo nto sivavanya yonke inyibilika ngohlalutyo lwe-OES *ngaphambi kokugalela-kwaye siqinisekise ubulukhuni be-post-cast kwiindawo ezintathu ngokuphosa, hayi enye.
Impumelelo yehlabathi yokwenyani ixhomekeke ekudityanisweni ngokuthe nkqo. I-Foundry, ivenkile yomatshini, kunye ne-metrology kufuneka yabelane ngelogi yembali enye ye-thermal, inkqubo enye ye-CMM, isatifikethi esinye sezinto. Akukho handoffs. Akukho ngqikelelo malunga nezibonelelo "eziqhelekileyo" zomatshini. Xa umthengi usithumelela i-AMS 5387 cobalt iplagi yokudweba iplagi ene-± 0.005 mm yokunyamezela isikhundla kwimingxuma emithandathu yedowel, siphendula kwiiyure ze-48-kungekhona ngesicatshulwa, kodwa ngengxelo ye-manufacturability ebonisa apho i-EDM drilling ibetha i-twist drilling, apho ukuxinzezeleka-ukunciphisa ngaphambi kokuba i-roughing ithintele njani i-rounding ye-cora kwaye ithintele indlela i-CONT esebenza ngayo. I-G2 ene-spindle ephethe umoya.
IZine Ezingaxoxiswanayo zeMishini-ebalulekileyo yokuCalwa kwentsimbi
- Ukulandelelwa kwezinto phantsi kwinani lobushushu-hayi nje iicerts ze-mill, kodwa iingxelo ezigcweleyo ze-OES, imivalo yokuvavanya i-tensile igcinwe kwindawo nganye, kunye neefoto ze-microstructure eziqinisekisiweyo ngokuchasene ne-ASTM E112
- Ukutshiza emva koxinzelelo loxinzelelo-sibamba i-castings kwi-550 ° C kwiiyure ze-4, emva koko ipholile kwi-≤30 ° C / iyure ngaphambi kokuba naluphi na ukususwa kwentsimbi kuqale
- I-GD & T-isicwangciso sokuqala sokuhlola-Iindlela zeCMM ezakhiwe kwimizobo yabathengi, hayi iitemplates eziqhelekileyo; Iimpawu zedatum zijongiwe kuqala, umphezulu osebenzayo wokugqibela
- Ukuqinisekiswa komgangatho wentembeko-hayi nje amaxabiso e-Ra, kodwa ukufunyanwa kwe-white-layer nge-SEM/EDS yokutywinwa kobuso obubalulekileyo obuvezwe kwinkonzo ye-H2S
Apho aBaboneleli abaMgangatho besilela khona ngokufutshane (kwaye uYibona njani)
Abanye abathengisi bapapasha "ukufakwa kwentsimbi echanekileyo" kodwa ukukhuphela ngaphandle kwi-Foundries enexabiso eliphantsi ngaphandle kwe-ISO 9001: 2015 Igatya lolawulo lwe-8.5.2 kwimveliso engahambelaniyo. Abanye basebenzisa iinkqubo ze-CNC eziqhelekileyo ezithatha isibonelelo sesitokhwe esifanayo-ngokungahoywa ukuba utshintsho lwesanti luchaphazela njani ubukhulu bodonga kwiijometri ezintsonkothileyo ezifana neerola ze-winch yemoto yeziko leshaft.
Siwubambe lo msantsa ngexesha lophicotho lwakutsha nje: umntu okhuphisana naye ucaphule umzimba wevalve yoxinzelelo enobungqingqwa bodonga obuyi-12-mm—kodwa umzobo wabo wokuphosa ubonise kuphela i-8-mm yesibonelelo segama. Ngokwesiqhelo, iipesenti ezingama-30 zamalungu afuna ukwakhiwa kwe-weld phambi kokuba kuqaliswe ukwenziwa komatshini. Ayikokuchaneka oko. Leyo yintelekelelo eguqulwe njengesakhono.
Buza umthengisi wakho le mibuzo ngaphambi kokuba ukhulule ii-PO:
- Ungandibonisa iilog ezintathu zokugqibela ezinyibilikayo ze-ASTM A ductile iron?
- Luluphi unxaxho lwakho oluphezulu oluvumelekileyo phakathi kobunzima be-as-cast kunye ne-final-machine weight for 42-kg yesiseko sempompo?
- Ngaba iingxelo zakho zeCMM ziquka idatha yembuyekezo ye-thermal drift efakwe ngexesha lefestile yokuhlola iiyure ezi-8?
Ukwakha Ukuzithemba—Akupheleli nje Kwizixhobo
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ihambisa ukuphosa ngentsimbi ngoomatshini izisombululo apho ukuthembeka kungenakuxoxisana-kungekhona ngenxa yokuba siyibanga, kodwa ngenxa yokuba inkqubo yethu ishiya ubungqina. Yonke ivalve yoxinzelelo ngenqanawa ineleyibhile enekhowudi ye-QR enxibelelana nedossier yayo epheleleyo yokuhlola: iicerts zemathiriyeli ekrwada, iitshathi zokunyanga ubushushu, amafu e-CMM, kunye neemephu ezirhabaxa. Abathengi baseMntla Melika naseYurophu basebenzisa ezo fayile kwi-ASME Icandelo VIII Icandelo le-UG-120 lokuthotyelwa kophicotho. I-OEMs yaseMzantsi-mpuma ye-Asia ibhekisela kubo ngexesha le-APQP yeSigaba sesi-3 sophononongo.
Asileqi umthamo. Sigxininisa kwiindawo apho ukungaphumeleli kuthetha ixesha lokuphumla, umngcipheko wokhuseleko, okanye isohlwayo esilawulayo-njenge-T800 cobalt-based nozzles ephethe i-450 ° C ityuwa etyhidiweyo kwizityalo ezigxininisiweyo zelanga. Apho, i-0.02-mm bore taper ayisiyo "nxanxathela encinci." Kukungalingani kokuhamba okukhawulezisa ukhukuliseko ngama-300%.
Ikamva leleenkqubo ezixubeneyo: iimilo zotyalo-mali ezikufutshane nenetha ezinemihlaba yokutywina eyenziwe ngoomatshini be-CNC, izindlu zesanti-santi ezinemijelo yokupholisa ehlanganisiweyo egqitywe ngokusila ngesantya esiphezulu. Sandisa i-R&D yethu ekubumbeni okupholisa okulawulwayo kwaye siphuhlisa inkqubo yokujonga ukungcangcazela ukuze kubonwe incoko ngexesha lokwenyani ngexesha lokudinwa komngxuma onzulu weebhloko zesilinda.
Ukuba iprojekthi yakho elandelayo ifuna ukuphosa ngentsimbi ngoomatshini leyo ibambe inyani kuma-300°C, iyasinda kwimijikelo ye-10⁶ yoxinzelelo, kwaye ifike ne-zero dimensional surprises—qala ngokulandeleka kwezinto, hayi ixabiso ngekhilogram.
