Iindawo zokugalela isanti zihlala zingumqolo weenkqubo zoshishino ezinzima-kungekhona ngenxa yokuba ziphelelwe lixesha, kodwa ngenxa yokuba zihambisa ukuqina okungenakulinganiswa, ukuzinza kwe-dimensional, kunye nokulawulwa kweendleko apho kubaluleke kakhulu: ngaphakathi kwe-hydraulic manifolds, imizimba ye-oilfield valve, kunye nezindlu zempompo zoxinzelelo oluphezulu.
Siphose ngaphezulu kwe-12,000 yeendawo zokulahla isanti kwii-OEM zemoto yobunjineli kwiinyanga ezili-18 ezidlulileyo kuphela. Kuzo zonke iibhetshi, inyaniso enye iphinda: xa ubukhulu bodonga budlula i-25 mm, uxinzelelo lokusebenza lukhuphuka ngaphezu kwe-bar ye-350, okanye ubomi benkonzo kufuneka budlule iminyaka eyi-15-i-sand casting ayikho inketho yokubuyisela. Kuphela kwenkqubo elinganisa ingqibelelo ye-metallurgical kunye nokwenziwa kwezinto ezinkulu, iijiyometri ezinzima.
Ngokungafaniyo nokuphosa utyalo-mali, olugqwesileyo ngokuchaneka kodonga olucekethekileyo kodwa luqhekeka phantsi koxinzelelo lwebhayisikile eshushu, ukugalelwa kwesanti kuzisa umthamo ophakamileyo wokudambisa kunye nokumelana nokuqhekeka kwiinkqubo ze-ferrous kunye ne-alloy ephezulu. Siye sabona i-cobalt-nickel alloy (AMS 5387) i-cylinder housings iphila kwi-40,000 + imijikelezo yoxinzelelo kwiindibano zepompo ye-offshore-kuphela ngenxa yokuba i-sand mold i-permeability encinci ivumela ukuqina okulawulwayo, ukunciphisa i-centerline shrinkage kunye ne-micro-porosity.
Iinyani ezintathu zobuchwephesha zahlula iindawo zokugalela isanti ezisebenzayo kwinkunkuma:
- Ukunyamezela indibano engundoqo: ± 0.3 mm ukuphambuka ekubekeni okungundoqo kudala ubukhulu bodonga obungafaniyo-kunye ne-73% yokungaphumeleli kokukhathala kobomi bokuqala siye sahlalutya umkhondo emva kolu tshintsho olulodwa.
- Ukukhetha inkqubo yokubopha: Izibophelelo zePhenolic urethane no-bake binders zigqwesa iinkqubo ezisekelwe kudongwe kwi-T800 cobalt alloy alloy, inciphisa iziphene zerhasi ngama-68% kwiindawo ezityebileyo.
- Ukunciphisa uxinzelelo lwasemva kokuphoswa: Ukucwiliswa kweeyure ze-4 kwi-920 ° C elandelwa kukupholisa kwesithando somlilo akunakuxoxisana kwizindlu zempompo yepiston-ukweqa kwandisa ukuphambuka kwe-GD & T ukuya kuthi ga kwi-0.15 mm kwiindawo ezibalulekileyo zedatum.
Ukusebenza kweendleko akukhona nje malunga nezixhobo ezisezantsi. Imalunga nokuphelisa imisebenzi yesibini. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sidibanisa ii-machining datums ngokuthe ngqo kuyilo lwepateni-ngoko inxalenye yokuphosa isanti ifika kwiseli ye-CNC ilungele ukugqiba ukujika, kungekhona ukugaya. Oko kunciphisa ixesha lokuhamba ngeentsuku ezi-3.2 nge-odolo nganye kwaye kunciphisa iimpazamo zokuseta ukulungiswa ngama-41%. Asazi "umatshini ngoko." Siphosa *ngoomatshini.
Abanye baphikisa ukuba iimolds zesanti eziprintiweyo ze-3D zisusa iindleko zepateni ngokupheleleyo. Kodwa kwimveliso yehlabathi lokwenyani, ukungunda okuprintiweyo akukho mandla acinezelayo afunekayo kwiintsimbi ezinkulu ezibunjwe ngaphezulu kwe-120 kg. Sivavanye zombini: iimolds eziprintiweyo aziphumelelanga kwi-142 bar yokugalela uxinzelelo; iimolds ze-silica ze-resin-coated zendabuko ezigcinwe kwi-bar ye-198-enokutshiswa kwe-zero okanye ukukhukuliseka kokungunda. I-trade-off ayikho ithiyori-ilinganiswa kwireyithi yesivuno. Umyinge wethu wangoku wokupasa wesanti ume kuma-99.1%, waqinisekiswa ngokuskena kweCMM yazo zonke iindawo ezibhobhozayo kunye neendawo zokutywina phambi konyango lobushushu.
Ukulandelelwa kwezinto eziphathekayo akungomaphepha-yi-physics. Yonke into eninzi ye-ASTM A27 yeBanga le-WCB yentsimbi okanye i-AMS 5387 cobalt alloy ithwala iicerts ezipheleleyo zemill, iingxelo zohlalutyo lwe-spectral, kunye nedatha yovavanyo lwe-tensile efakwe ngokuchasene nenombolo yokushisa. Xa umthengi waseNorway ecela ukufaneleka kwakhona kwebhetshi ye-winch ye-winch ye-shaft ye-2019, satsala i-log yokunyibilika yasekuqaleni, safumana isampulu ye-ladle echanekileyo, kunye nokuqina okuqinisekisiweyo kwahlala ngaphakathi kwe-± 2 HRC emva kweminyaka esibhozo kwindawo yokugcina engaphantsi kwe-zero.
Eli nqanaba lolawulo livela kuhlanganiso oluthe nkqo: indawo yethu ehambelana ne-ISO iphatha yonke into ukusuka ekubumbeni kwesanti eluhlaza kunye nokushukunyiswa kwe-T6 kunyango lobushushu, ukudutyulwa kokudubula, kunye nokuhlolwa kokugqibela kusetyenziswa izithelekisi zamehlo ezilinganiswe kwimigangatho ye-NIST. Akukho handoffs. Akukho zithuba zebhetshi. Iqela nje elinye elinoxanduva kwi-micron nganye yokuchaneka komda kunye nayo yonke i-joule yokumelana nempembelelo.
Amalungu okugalela esantini aphumelela xa iinjineli ziwaphatha njengeenkqubo zobunjineli—kungekhona imilo yesinyithi. Oko kuthetha ukuyila ii-engile zoyilo malunga neendlela zokurhoxisa izixhobo, ukucacisa iindawo zokunyuka ezisekwe kwimodeli ye-thermal gradient-hayi isithethe-kunye nokukhetha i-alloys esekwe kwigophe lokuqina lokwaphuka, hayi nje iitafile zokuqina. Siye sakhaba izicelo ezili-17 zeprototype ngo-2024 ngenxa yokuba i-GD&T callouts iphikisana neepateni zokuqina. Kungcono ukuthi "hayi" kunomkhumbi inxalenye engaphumeleli kwi-3,200 psi.
Ukuba isicelo sakho sifuna imfezeko yolwakhiwo phantsi komthwalo webhayisekile, ukunganyangeki komhlwa kwiindawo ezinerhasi emuncu, okanye ukuphinda-phinda okuphindwe kabini kwiiyunithi ezibalekayo ezingama-500—indawo yokugalela isanti ayibobuchwephesha bakudala. Zizisombululo ezichanekileyo ezenzelwe ubunjineli bomsebenzi obalulekileyo. Kwaye baqala ngokwazi ngokuthe ngqo apho isinyithi esityhidiweyo siya kuhamba khona, sipholile, kwaye sitshixe kwisakhiwo sengqolowa-ngaphambi kokuba ukhozo lokuqala lwesanti luchukumise ipateni.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yenza iinxalenye zokulahla isanti kubathengi behlabathi abalinganisa impumelelo ngexesha lokuphumla-hayi iyunithi yeendleko. Umsebenzi wabo ubonisa ukuba ixesha elide kunye nokusebenza kakuhle akukhuphisani. Badibanisa.
