Izisombululo zefektri ye-electrochemical machining echanekileyo ayiqalisi ngezixhobo ze-specs-ziqala ngenxalenye engayi kunqumla *, * ayiyi kubamba ukunyamezela *, okanye * ayiyi kusinda kwinkonzo *. Siye sayibona ngokuphindaphindiweyo: izindlu zepompo ye-cobalt-nickel eziqhekeza phantsi kwe-300-bar ye-cyclic pressure; Imilomo ye-AMS 5387 engakwazi ukuphinda iphindwe emva konyango lobushushu; I-T800 i-alloy center shaft rollers inxibe ngokungafaniyo kwiiyure zokusebenza ezingama-200. Ezi ayizizo iziphene zokuvelisa. Ziyinkqubo yezinto eziphathekayo-kwaye zibiza ixesha, i-scrap, kunye nokuthembeka.
Xa uMatshini weSiqhelo Ubetha uMda Wawo, Ukuchaneka kwe-Electrochemical Machining amanyathelo angaphakathi
I-Electrochemical machining (ECM) ayiyo "CNC engcono." Yinkqubo esekwe ngokwesiseko yefiziksi-engaqhagamshelwanga, akukho sixhobo sinxitywayo, i-zero yoxinzelelo lomatshini. Okona kubaluleke kakhulu xa ususa imathiriyeli kwi-superalloys eqinileyo efana ne-cobalt-chrome okanye i-nickel-based Inconel eyahlukileyo apho ukugaya ngokwemveli kubangela ukuqhekeka okuncinci, i-burrs, okanye uxinzelelo olushiyekileyo kumphezulu. Kwiziko lethu elihambelana ne-ISO e-Qingdao, sisebenzisa i-ECM kungekhona njengendawo yokusebenza ezimeleyo-kodwa njengesisombululo esijoliswe kuyo, esihlanganisiweyo ngaphakathi kokuchaneka okupheleleyo kwecandelo lentsimbi. Siyisebenzisela ukugqiba iicontours zangaphakathi ezibalulekileyo kwi-piston pump cylinder housings apho isiphelo sokusila singenakufikelela khona, ukucima izihlalo zevalve ezinoxinzelelo oluphezulu ngaphandle kokuguqula i-GD&T callouts, kunye nokufezekisa i-± 0.01 mm ubukhulu bodonga ukuguquguquka kwi-360 ° ye-winch ejikelezayo ye-winch i-shaft roller-into egawulayo kwi-batch yokuzabalaza ukuphindaphinda.
Kodwa nantsi into eyenziwa ngabathengi abaninzi: Impumelelo ye-ECM ixhomekeke ngaphantsi kumatshini kunye nangaphezulu kwizinto ezintathu ezidityanisiweyo ezidityanisiweyo-ukwenziwa kwe-electrolyte, ukunyaniseka koyilo lwe-cathode, kunye nolawulo lwexesha langoku loxinaniso. I-cathode engalunganga ibangela i-taper; i-electrolyte engathintelwanga ikhukuliseka i-pH kwaye ikhukulise umphezulu womphezulu; Isantya sokuqukuqela esingahambelaniyo sidala imingxuma yendawo. Siqinisekisa ukuseta ngakunye ngokuchasene neendawo zabathengi-hayi iikhuphoni zovavanyo. Ngokomzekelo, xa i-OEM ye-hydraulic yaseYurophu idinga ububanzi obuphindaphindwayo obuyi-0.05 mm kwiiplagi ze-AMS 5387, siye saqhuba iimvavanyo ezili-12 eziphindaphindayo nge-optical profilometry kunye ne-metallography yecandelo elinqamlezayo-hayi nje iskena se-CMM-ukutshixa ubushushu be-electrolyte, isantya se-voltage ramp, kunye ne-inter-electrode gap ngaphambi kokuba kuqhutywe imveliso yokuqala.
Kutheni uHlanganiso oluthe nkqo lubetha iiVenkile “ze-ECM kuphela” zeMishini-Amacandelo abalulekileyo
Abanye abathengisi bathengisa i-ECM njengenkonzo. Siyibethelele ngaphakathi kokuphoswa-ukuya-ukugqiba ukuhamba komsebenzi-kuba ukusilela okukhulu kwe-ECM kwenzeka *phambi kokuba* inxalenye ibambe ibhafu ye-electrolyte. I-microstructure engalunganga njenge-cast? I-Porosity kufuphi nomphezulu wokutywina obalulekileyo? Ukuqhelaniswa okuziinkozo okungahambelaniyo kwi-alloy ye-T800? Ezo ziphene zikhulisa ngexesha le-ECM, hayi ukufihla. Yiyo loo nto i-electrochemical machining factory echanekileyo isebenza phantsi kophahla olunye ngokufaka utyalo-mali, i-CNC ye-multi-axis, kunye nonyango oluqinisekisiweyo lobushushu. Silawula lonke ikhonkco: ukulandelwa kwezinto eziluhlaza (zonke i-cobalt-nickel alloys efunyenwe ngee-certs ze-mill), imijikelezo yokunciphisa uxinzelelo lwe-pre-machining, kunye ne-post-ECM passivation okanye i-electropolish elungiselelwe ukuxhathisa ukubola-kungekhona nje i-aesthetics.
Sikwaphatha i-GD&T hayi njengephepha-kodwa njengemephu yesithintelo somatshini. Xa uphonononga imizobo yeevalvu zoxinzelelo, senza iflegi yemimandla apho ukunyamezela iprofayili eqinile (umzekelo, i-0.02 mm UZ) ingqubuzana kunye nenkcazo efikelelekayo ye-ECM edge. Esikhundleni sokugatya ukuprinta, sicebisa iindlela ezixubileyo: umatshini orhabaxa oneCNC, emva koko iECM i-0.15 mm yokugqibela ukubetha ifom yokwenyani kunye nokuthembeka komphezulu. Oko kunciphisa ixesha lomjikelo nge-37% ngokuchasene nayo yonke i-ECM ngelixa idibana neemfuno ze-ASME B16.34.
Ukuqinisekiswa Kwehlabathi Lokwenyani: Yintoni Esebenzayo (kwaye Yintoni engasebenziyo)
Abathengi bethu babuza imibuzo emithathu ngaphambi kokuba bazibophelele kwi-ECM:
- “Ungakwazi ukubamba ±0.005 mm kumbhobho wangaphakathi oyi-200 mm?” Ewe-ukuba inxalenye yejometri ivumela ukuhamba kwe-electrolyte efanayo kwaye i-cathode igxininiswe ngokungqongqo. Senza oku yonke imihla kwiziseko zempompo ze-oyile engaselunxwemeni kunye nokusetyenziswa kwegesi.
- "Ngobuphi ubuncinci besayizi owuvelisayo ngokuthembekileyo?" I-0.12 mm slots kwi-cobalt alloy nozzles, iqinisekiswe nge-SEM metrology-kungekhona i-optical projection.
- "Ngaba uyazixhasa ialloys ezingekho mgangathweni njenge T800?" Ewe. Kodwa sifuna ukwakheka kweekhemikhali ezipheleleyo kunye nembali yonyango lwangaphambili lobushushu. Ngaphandle koko, uhlengahlengiso lwekhemistri ye-electrolyte luba yingqikelelo-kwaye amaxabiso e-scrap akhuphuka.
Senqaba i-11% ye-RFQs yokuqala-hayi ngenxa yezithuba zokukwazi, kodwa ngenxa yokuba inxalenye yejometri okanye imeko yempahla yenza i-ECM ingabi namveliso. Kungcono ukuthi “hayi” kwangoko kunokunikezela ngenxalenye ephumeleleyo kuhlolo kodwa ingaphumeleli kuvavanyo lwangaphandle.
Ukujonga Phambili: Ukuchaneka akuqinisekanga-Kwakunye neNkqubo yethu
Ukuchaneka kokwenyani kwe-electrochemical machining amandla emveliso kuthetha ukuvela ngaphaya kokuchaneka komda kulungelelwaniso lokusebenza. Okwangoku, sifanelekile iiparamitha ze-pulsed-ECM zokuphucula ukubukhali komphetho kwiiprofayili zeengcambu ze-turbine blade-kunye nokudibanisa i-inline conductivity sensors ukulungelelanisa ngokuzenzekelayo ukuhamba kwe-electrolyte ngexesha lomjikelo omde. Sikwandisa i-NADCAP yomntu wesithathu woqinisekiso lwenkqubo ethile ye-ECM, hayi nje ukuthotyelwa komgangatho jikelele. Kuba kumacandelo afana ne-aerospace hydraulics okanye ukumpompa kwe-subsea, "ukuchaneka" akulinganiswa kwii-microns zodwa. Ilinganiswa ngexesha eliphakathi phakathi kokusilela. Ngexesha lokuphumla. Kwi trust.
Ukuba iprojekthi yakho elandelayo ibandakanya amacandelo e-cobalt-nickel, iisistim zoxinzelelo oluphezulu lwevalvu, okanye iijiyometri zesiko le-superalloy apho iindlela eziqhelekileyo zeplateau—ngokuchanekileyo i-electrochemical machining factory ubuchwephesha kufuneka buqulunqwe ukususela kusuku lokuqala. Ayifakwanga njengengcinga yamva.
