Xa iinjineli zidinga iindawo zentsimbi ezingayi kusilela phantsi kwe-300 bar hydraulic pressure-okanye ziphile iiyure ezili-12,000 kwindawo yerhasi emuncu-aziqali ngegeneric. inkampani yokugalela isanti. Baqala ngokuziphatha okubonakalayo, ukuzinza komda, kunye nokulawulwa kwenkqubo eqinisekisiweyo. Yingakho amaqela okuthengwa kwempahla kulo lonke elaseNyakatho Melika kunye ne-EU ehlala ebuyela kubavelisi abaphatha ukuchithwa kwesanti kungekhona njengenyathelo lempahla, kodwa njengekhonkco lokuqala elibalulekileyo kwingqibelelo yenkqubo yokusebenza.
Kutheni ukuphosa kwesanti kusenamandla kwiiNkqubo eziBalulekileyo
I-Sand casting ihlala iyona ndlela ingabizi kakhulu yokuvelisa izakhi zetsimbi ezinkulu, eziyinkimbinkimbi, okanye ezisezantsi ukuya eziphakathi-ingakumbi xa ezo nxalenye kufuneka zibambe ibhayisekile ye-thermal, i-abrasive wear, okanye i-high-pressure sealing. Kodwa asiyiyo yonke into yokuphosa isanti enikezela ngokuthembeka okulinganayo. Sibone iiprojekthi ezininzi ziphazamiseka ngenxa yokuba umthengisi wamkele umzobo ngaphandle kokuphonononga ijometri yoshicilelo olungundoqo, usebenzise izibophelelo zesanti eluhlaza ezingaqinisekisiweyo, okanye ukutsiba ukuqinisekiswa kwesinyithi kwangaphambili. Ukusilela kwelizwe lokwenyani akufane kuvele kubuchwephesha obugwenxa emazantsi omlambo. Baqala ukuya phezulu-kulawulo lokungena kokungunda, uyilo lokungena, okanye imodeli yokuqinisa i-alloy.
Kulapho ukudibanisa ngokuthe nkqo kubalulekile. Iqabane lokwenyani liphatha ukwenza iipatheni, ukulungiswa kwesikhunta, i-chemistry enyibilikayo, i-shakeout, i-stress relief, kunye ne-machining yokugqibela-konke phantsi kophahla olulodwa, ngokuphendula okwabelwanayo. Iphelisa iimpazamo ze-handoff, izithuba zokulandela umkhondo, kunye nokutolika komgangatho ophikisanayo phakathi kwe-Foundry kunye nevenkile yomatshini. Omnye umxhasi usixelele: "Sinciphise ixesha lokuhamba nge-40% emva kokutshintshela kumboneleli womthombo omnye-nangona isicatshulwa sabo sasiphezulu nge-12%.
Izakhono ezine eziNgaxoxisaniyo kwi-High-Performance Sand Casting
Ngokusekwe kuma-200+ ophononongo lobuchwephesha bokuphosa okungaphumelelanga kule minyaka mihlanu idlulileyo, ezi zakhono zine zahlula ababoneleli abathembekileyo kwabo banobungozi:
- I-AMS 5387 kunye nobuchule be-T800-grade cobalt alloy-hayi nje amandla okunyibilika, kodwa amava abhaliweyo kunye nokunciphisa okutshisayo okukrazula, ukuqina komkhombandlela, kunye nokuqinisekiswa kwe-post-cast microstructure nge-SEM/EDS
- Uyilo lwepateni ye-GD&T-apho ii-engile zokuyila, izibonelelo ezicuthayo, kunye nesitokhwe somatshini sibalwa ngokuchasene nedatha esebenzayo, hayi imilinganiselo yesiqhelo
- Ukulandeleka kwebhetshi epheleleyo-ukudibanisa ukuphosa nganye kwinombolo yayo yobushushu, ilog yokugalela, ingxelo yovavanyo lwe-tensile, kunye nerekhodi yokuhlola yeCMM-hayi nje isatifikethi sokuthotyelwa
- Inkqubo yoqeqesho lweHybrid-Utshintsho olungenamthungo ukusuka ekujuleni ukuya kwi-CNC, kunye nexesha elilawulwayo lokunciphisa uxinzelelo kunye nokulungiswa komphezulu okuthintela incoko yesixhobo kwindawo eqinileyo
Ezi ayizombono zethiyori. Zizifundo eziphumelele nzima ukusuka kwizindlu zempompo zepiston eziqhekeka kwi-18,000 psi, imizimba yevalvu yoxinzelelo evuzayo emva kweeyure ezingama-72 zovavanyo lwesitshizi setyuwa, kunye ne-winch shaft rollers zisilela ukudinwa kwangaphambi kwexesha ngenxa yeporosity engaxelwanga kufutshane nejenali.
Eyona nto ifunwa ngamaqela oNjineli—hayi nje le nto ayichazayo
Uninzi lwe-RFQs lucela "i-ASTM A48 Class 35 grey iron, 3.5 mm max wall, 0.5 mm GD&T tolerance." Kodwa yintoni ephosakeleyo? Ukusasazwa kwe-thermal mass ngexesha lokupholisa. Ukuxinezeleka okushiyekileyo okubangelwa ngoMatshini kumacandelo amancinci. Okanye ukuba ubungakanani beenkozo zesanti buchaphazela njani ukugqiba komphezulu kwi-0.8 µm Ra yokutywina ubuso. Siye sabukela abathengi abathathu abahlukeneyo beyila kwakhona iindibano zonke emva kokufunda i-spec yabo yokuqala evunyelwe i-1.2 mm ye-flash engatshintshiyo-igqithise imvume yokusebenza efunekayo yoxinzelelo lwetywina oluguquguqukayo.
Amaqabane athembekileyo akadibanisi nje neespekthi. Babonisa ukuchasana: ukunyamezelwa kwe-0.05 mm kwindawo ebekwe kwi-400 mm ukusuka kuluhlu oluphambili kwi-120 kg yokuphosa; imfuno yensimbi engenasici engaphathwa ngokushushu kwinxalenye evezwe kwiqondo lokushisa lenkonzo ye-450 ° C; okanye umyalelo "wesanti kuphela" wecandelo elidinga iipaseji zokupholisa zangaphakathi eziphunyezwe ngcono ngeenkqubo zotyalo-mali ezixubileyo.
Ukukhetha Inkampani Yakho Elandelayo Yokuphosa Isanti-Ngaphaya Kwencwadana
Buza le mibuzo mihlanu phambi kokuba utyikitye i-PO:
- Ngaba ungabelana ngengxelo yamva nje ye-CMM ngenxalenye efanayo ngobunzima, i-alloyi, kunye nokuntsonkotha kobethu-kunye ne-callouts ye-GD&T epheleleyo egxininisiweyo?
- Uziqinisekisa njani iiprofayili zobushushu bokutshiswa kwesibophelelo ngexesha lokubhaka ngumngundo-kwaye ngaba loo datha ifakiwe kwiqashiso ngalinye?
- Uthini umyinge wakho wokukhatywa kwenqaku lokuqala kwi-cobalt-nickel alloys? (Ukuba bathi "zero," hamba.)
- Sibonise iingxelo zakho zokugqibela ezintathu ze-AMS 5387 zokuhlalutya-kuquka ukulandelela izinto ezifana ne-boron kunye nomxholo wekhabhoni.
- Ngaba uyalwenza uvavanyo lwe-ultrasonic kwi-casting nganye engaphezulu kwe-50 kg? Ukuba akunjalo, sithini isicwangciso sakho sesampulu-kwaye uzinxibelelanisa njani iziphumo ze-UT kunye neziphumo zovavanyo oluyingozi?
Abavelisi abaphendula ngokukhawuleza, bacaphula imodeli yezixhobo ezithile (umzekelo, i-Zeiss Contura G2 RDS), kunye neereferensi zokwenyani zemveliso-kungekhona nje izatifikethi ze-ISO-fumana uluhlu olufutshane olukhawulezayo. Abo babhenela kulwimi lokuthengisa okanye ukulibazisa iimpendulo banokukhupha amanyathelo abalulekileyo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngale ndlela yonke imihla. Indawo yayo ehambelana ne-ISO e-Qingdao iqhuba ukuchithwa kwesanti edibeneyo, i-multi-axis CNC, kunye nokuphathwa kobushushu-konke kulawulwa yimigaqo yokuhlola ebhaliweyo, ukulandelwa kwezinto ezigcweleyo, kunye nokuhlaziywa kobunjineli okwakhiwa kwisigaba sokucaphula. Abathengi bafumana ukuqinisekiswa komzobo, ingxelo yokwenziwa kwezinto, kunye nokutolika kwe-GD&T-hayi nje ixabiso kunye nomgca wexesha. Ukufaka izicelo eziyimfuneko kwiinkqubo ze-hydraulic, izixhobo ze-oyile kunye negesi, kunye namaqonga eemoto ezinobunjineli, oko kuhambelana akukhethi. Yisiseko.
