Izisombululo zasefektri yokuphosa intsimbi eqinileyo zivala umsantsa phakathi kokusatywa kwemveli kunye nokwakha-ukuhambisa iinxalenye ezikufutshane-netha ezinemilo ekumgangatho ophezulu, ukuncitshiswa kwe-porosity, kunye nolawulo olungqongqo lwe-dimensional. Kodwa ayizizo zonke izinto ezifumanekayo ezinokuvelisa ngokuthembekileyo izinto zeevalvu zehydraulic, izindlu zempompo zoxinzelelo oluphezulu, okanye imilomo ye-cobalt-alloy esinda kwi-200+ ibhayisekile yebhayisekile kunye nemithombo yeendaba yolwelo olubrasive. Sibone iiprojekthi ezininzi zimile kwinqanaba leprototype-hayi ngenxa yoyilo olungalunganga, kodwa ngenxa yokuba umzi-mveliso wokugalela wesinyithi osiqilima ukuswela uqeqesho lwe-metallurgical, in-process verification, okanye indibaniselwano yenkqubo yokudibanisa.
Kutheni iSemi-Solid Casting isilela-kwaye yintoni kanye esebenzayo
Uninzi lweentsilelo lulandelela kwiingcambu ezithathu: ukulawulwa kobushushu obuludaka obungahambelaniyo ngexesha le-rheocasting, ukucocwa okungonelanga kweenkozo kwi-slurry e-semi-solid, okanye ukungahambi kakuhle phakathi kokuphosa imbuyekezo yokuncipha kunye nezibonelelo zomatshini ze-CNC ezisezantsi. Kwiziko lethu eQingdao, silinganisa i-slurry viscosity ngexesha lokwenyani sisebenzisa i-rheometers ejikelezayo engaphakathi-hayi nje i-thermocouples. Siye safumanisa ukuba ukuphambuka kwe-± 1.5 ° C ngaphezu kwe-582 ° C kwi-AMS 5387 cobalt alloy slurry kwandisa i-micro-shrinkage nge-23% kwiindonga zezindlu ze-cylinder ezingaphezu kwe-12 mm. Kungenxa yoko le nto siye sazinzisa umfanekiso oshushu ngokuthe ngqo kumkhono wokudubula kwaye sihlengahlengise isantya senaliti ngokuguqukayo kwinxalenye yejometri.
Okubaluleke ngakumbi, ukuphoswa kwe-semi-solid akuyodwa. Yinode kwikhonkco lokuvelisa elichanekileyo. Impompo yepiston yendlu efakwe kwi-semi-solid ye-cobalt alloy ye-T800 kufuneka igcine i-microstructure ezinzileyo ngonyango lobushushu oludambisa uxinzelelo *phambi* kwe-five-axis milling ye-valve port contours. Ukuba indlu yokuphosa ayilawuli amazinga okupholisa ngaphakathi kwe-± 3 ° C / min ukusuka kwi-1050 ° C ukuya kwi-600 ° C-okanye ukuba abanako ukuqinisekiswa kwe-CMM edibeneyo ye-GD & T kwi-green-state castings-inxalenye yokugqibela iya kuphumelela uvavanyo loxinzelelo olusebenzayo. Senza zombini. Ibhetshi nganye ibandakanya uhlalutyo lwe-spectrographic, umlinganiselo we-dendrite arm spacing (DAS) phantsi kwe-SEM, kunye nokulandeleka okupheleleyo kwelogi yonyango lobushushu.
Izakhono ezine ezingaxoxisiyo kwiMishini yezicelo eziBalulekileyo
Umzi-mveliso wokujula wesinyithi oqinileyo ophantse ulingane kufuneka unike ngaphezulu kwentsimbi emile. Kufuneka iqinisekise ukusebenza phantsi kwemigaqo. Nantsi into esiyiqinisekisayo phambi kokucaphula nawuphi na umsebenzi:
- Izinto eziphathekayo zokulawula umnombo: Ii-ingots ze-cobalt-nickel ezikrwada zifunyenwe kuphela kwii-mills eziqinisekisiweyo kwi-ASTM B575 kunye ne-AMS 5737-kunye neengxelo zovavanyo lwe-mill zitshekishwe ngokuchasene ne-spectrography engenayo
- Inkqubo-edibeneyo ye-metrology: Ukuphononongwa kwe-laser engaphakathi kumgca wokuzaliswa kwangaphambili kwe-mold cavity, ukuhlolwa kwe-CMM emva kokukhutshwa kweendawo ezibalulekileyo ze-datum, kunye nemephu ye-contour ye-optical yeendlela zokuhamba zangaphakathi ngaphambi komatshini.
- Ukupakishwa kokunyamezela kweHybrid: Sibala impazamo eyongezelekayo yohlahlo lwabiwo-mali kulo lonke ukuncipha kokuphosa, ukugqwethwa kobushushu, kunye nophambuko lwendlela yesixhobo ye-multi-axis—asisebenzisi nje izibonelelo zegeneric ±0.3 mm
- Inkqubo yokuqinisekisa esebenzayo: Zonke izindlu zevalve yoxinzelelo ziphantsi kovavanyo lokuvuza kwe-helium kwi-1.5 × uxinzelelo lokusebenza, emva koko ityuwa-spray exposure per ASTM B117 iiyure ezingama-96 ngaphambi kokupakishwa kokugqibela.
Urhwebo lwehlabathi lokwenyani kufuneka Uyamkele
Ezinye iinjineli zithatha i-semi-solid casting ngokuzenzekelayo kunciphisa iindleko. Akunjalo-ngaphandle kokuba ujolise kwiintsapho ezithile. Kwiijiyometri ezinodonga olucekethekileyo, ezintsonkothileyo ezifana neerola zeziko le-winch ezinamazinyo adibeneyo e-spline kunye ne-oyile, i-semi-solid inciphisa ixesha lomatshini ngama-40% kwaye iphucula ubomi bokudinwa nge-2.7 × xa ithelekiswa nesanti-cast elinganayo. Kodwa kwiiflange ezilula ngaphantsi kwe-50 mm ubukhulu? Utyalo-mali oluqhelekileyo ludla ngokuzisa iROI engcono.
Kutshanje sisebenze ne-OEM yokwenziwa koxinzelelo olukhulu yaseYurophu enyanzelise ukuba i-semi-solid kwisiseko sempompo yedayamitha engama-320 mm. Ukulinganisa kwabo kwaqikelelwa ukuba yi-0.12 mm warpage. Eyona nto yayiyi-warpage yayiyi-0.28 mm-kuba imodeli yabo ayizange ichaze utshintsho olungundoqo ngexesha lokutofa okudaka kwi-shell shells. Siye saqhuba ulingo lomzimba ngeegeyiji ezizinzisiweyo zoxinzelelo, ukuqina kwepin engundoqo, kwaye songeza iibhloko zengqele zalapha. Iphepha lokugqibela lemfazwe lehlile laya kutsho kwi-0.14 mm. Sifunda ntoni? Ukulinganisa kunceda-kodwa kuphela xa kusekelwe ekulinganisweni kokuziphatha kwe-thermal-mechanical.
Yintoni omawuyifune kwiFactory yakho yeSemi Solid Metal Casting
Buza le mibuzo phambi kokuba utyikitye i-NDA:
- Ngaba ungandibonisa iziqinisekiso zakho ezintathu zokugqibela ze-AMS 5387-kubandakanywa amaxabiso e-DAS kunye neemephu zokwahlula phakathi kwe-interdendritic?
- Ngaba wenza uvavanyo lwe-ultrasonic kwi-processing kwi-castings engaphezulu kwe-25 mm-okanye uhlolo lokugqibela?
- Ubuyekeza njani ukungafani kokwandiswa kwe-thermal phakathi kokusahlelwa kwe-T800 kunye nokufakwa kwentsimbi engenasici ngexesha lendibano?
- Uthini umyinge wakho wokupasa kwinqaku lokuqala kwiimpawu ze-GD&T ezifuna ukunyamezela isikhundla esingaphantsi kwe-0.05 mm?
Ukuba iimpendulo azicacanga, zilibazisekile, okanye zibhekisela “kwindlela yokusebenza eqhelekileyo kwishishini,” hamba. Ukuchaneka akuxoxiswana-yenziwe ngobunjineli, kulinganiswa, kwaye kubhalwe phantsi kwinqanaba ngalinye.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kumzi-mveliso wokujula wesinyithi osiqilima apho iimpompo ze-cobalt-alloy zidibana nokuhamba komsebenzi okuqinisekisiweyo kwe-ISO 9001, hayi nje izixhobo zokuphosa. Asohluli ukuphosa kumatshini-siyabafumana ngokubambisana. Asiyiphathi imilinganiselo yezinto eziphathekayo njengamaphepha-siyaziqinisekisa ngabo bonke ubushushu. Kwaye asithembisi "ukuchaneka." Siyayingqina-inxalenye ngenxalenye, ibhetshi ngebhetshi, umthengi ngomthengi. Kuba kwiinkqubo zehydraulic, ioyile kunye neevalvu zegesi, kunye neenqwelo moya zobunjineli, akukho mda wokuqikelelwa. Kukho kuphela ukusebenza-okanye ukungaphumeleli.
