Xa iinjineli kwinkqubo ye-hydraulic OEMs okanye iinkampani zenkonzo ye-oilfield zikhangela a China metal casting factory, abakhangeli esona sicatshulwa sisezantsi. Bakhangela ukuphinda-phinda kwe-dimensional kwimpompo ye-cobalt alloy yendlu, ukuhambelana kwe-metallurgical ngapha kwe-50 AMS 5387 castings, okanye i-zero surprises xa i-T800 winch shaft ingaphumeleli kuvavanyo lwayo lwe-hydrostatic. Siyibonile amaxesha amaninzi kakhulu: isiseko "esifanelekileyo" sihambisa iinxalenye ezidlula uhlolo olubonwayo-kodwa i-crack phantsi kwe-300 bar yoxinzelelo lokuhamba ngebhayisikile ngenxa yokuba ukwakhiwa kweenkozo akuzange kuqinisekiswe, okanye ukuqina komphezulu kukhukuliselwe ngaphandle kwe-spec emva konyango lobushushu.
Ukuthembeka kwehlabathi lokwenyani kuqala ngobunini benkqubo-hayi ukukhupha
Uninzi lwabathengi behlabathi bacinga ukuba ukuphosa kunye nomatshini ziinkonzo ezahlukeneyo. Loo ngcinga idala umngcipheko. Xa ukuphosa kwenziwa kwindawo enye, unyango lobushushu kwelinye, kunye ne-CNC igqibezela kwisithathu, izinto ezibalulekileyo-ezifana nokusabalalisa uxinzelelo olushiyekileyo okanye impendulo ye-microstructural kwi-thermal cycling-slip ngokusebenzisa izikhewu ze-handoff. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Zontathu izigaba zenzeka phantsi kophahla oluqinisekisiweyo lwe-ISO eQingdao. Oku akukho lula-lulawulo. Siphosa isiseko sempompo yentsimbi, emva koko sishicilele i-flange yayo yokunyuka kunye nobuso bezibuko ngokuseta okufanayo, sisebenzisa isixhobo esilinganayo se-CMM-calibrated. Akukho ukulungiswa kwakhona. Akukho shift data. Akukho ngqikelelo malunga nokuba ukugqwethwa kwe-cast-cast kuya kuchaphazela njani ukuthotyelwa kwe-GD&T yokugqibela.
Siye saqinisekisa le modeli idityaniswe ngokuthe nkqo kwiiprojekthi ezingaphezu kwe-127 zeevalvu zehydraulic. Omnye umxhasi waseMntla Melika utshintshile kumboneleli we-tier-1 emva kokungaphumeleli kokuvuza okuphindaphindiweyo kwindawo yokuhlala. Uhlalutyo lwengcambu yabo lubonise i-microhardness gradients engahambelaniyo kwi-valve body bore-ebangelwa ngamazinga okupholisa angalawulekiyo phakathi kokuphosa kunye nokuphathwa kobushushu emva komatshini. Isisombululo sethu? Gcoba umzimba, yenza isisombululo esidibanisa *endlwini*, emva koko ugqibezele indawo yokuhlala ngaphakathi kweeyure ezingama-48-phambi kokuba ukufuma okanye ukuphathana kungazisa i-oxidation yomphezulu. Isiphumo: Ukuvuza okungavuziyo kwiinyanga ezili-18 zokusebenza ebaleni kwiirigi ezingama-42 ezikude nonxweme.
Ayizizo zonke ii-cobalt alloys eziziphatha ngendlela efanayo-kwaye ngokunjalo neefektri eziziqhubayo
I-AMS 5387 cobalt alloy ayisiyonto “enzima kumatshini.” Ukuziphatha kwayo kwemvula ye-carbide kutshintsha kakhulu kunye nokutenxa nge-0.3 ° C ngexesha lokutsala isisombululo. I-alloy ye-T800 ifuna amaxabiso achanekileyo erempu ye-preheat ngaphambi kokulungiswa kwe-welding-kungenjalo, ukuqhekeka kwe-intergranular kubonakala ngexesha lokugqibela le-NDT. Ababoneleli abaninzi baphatha ezi mathiriyeli njenge "superalloys" eziqhelekileyo. Sibaphatha njengeenkqubo eziphilayo ezinembali echaziweyo ye-thermal.
Iprothokholi yethu yokulandelela imathiriyeli idlula ngaphaya kwezatifikethi zokusila. Iqashiso ngalinye lobushushu liphethe i-ID ekhethekileyo edityaniswe nezigodo zeziko, ukucima iirekhodi zobushushu beendaba, kunye nemephu yobulukhuni basemva konyango kumacandelo amathathu anqamlezayo. Xa umenzi wempompo waseYurophu efuna imilomo ye-22 kunye ne-Rockwell C 42-46 ubulukhuni * kunye * ne-100% yococeko lwe-ultrasonic, saqhuba ubushushu bomqhubi, sahlengahlengisa ixesha lokufunxa ngemizuzu eyi-9, kwaye saphinda saqhuba iprofayili yobulukhuni-ngaphambi kokuzibophelela kwimveliso. Eli nqanaba lokuphindaphinda lisebenza kuphela xa i-metallurgy, i-casting, kunye ne-QA ihleli kwigumbi elinye.
- Amacandelo e-cobalt-nickel: i-AMS 5387, i-T800, i-Stellite 6B-iphoswe, iphathwe ngobushushu, kwaye igqityiwe ukuya ku-≤± 0.015 mm ukunyamezela
- Ukuphoswa kwentsimbi: I-ASTM A48 Udidi lwama-30–65, kunye nokuqinisekiswa kwamandla okuqina ngokwe-ASTM E8 kwiqashiso ngalinye
- Intsimbi kunye nokujulwa kwentsimbi: ASTM A216 WCB, A351 CF8M-iradiographed ngokupheleleyo (ASTM E94) kwiindlela zokuhamba ezibalulekileyo
- Iindawo zoomatshini ze-CNC: Ukujikwa kwe-multi-axis komgangatho oqinileyo, kubandakanywa i-splines yangaphakathi kunye ne-tapered bores nge-≤0.005 mm runout
Ukuqinisekiswa kokuhanjiswa akuthenjiswa-yenziwe ngobunjineli
“Amaxesha azinzileyo” athetha izinto ezahlukeneyo kubantu abahlukeneyo. Kumaqela okuthenga, oko kuthetha ukuba akukho ntlawulo yomzuzu wokugqibela yothutho lomoya. Ukuyila iinjineli, kuthetha ukufumana iinxalenye zenqaku lokuqala *eneengxelo zokuhlola ezipheleleyo*—kungekhona nje i-dimensional data, kodwa iifoto ze-microstructure, iimephu ezinobulukhuni, kunye nokuhlolwa kwendawo yeekhemikhali—ngaphambi kokusayina kwi-PPAP.
Sakha ukuhanjiswa kwinkqubo-hayi ngeenxa zonke kuyo. Ukucwangciswa kwemveliso kusebenzisa ulandelelwano lwe-takt-time, hayi i-batch-and-queue logic. Ukuba indlu yesilinda yempompo yepiston ifuna unyango olushushu olu-3, ukuseta iimatshini ezi-5, kunye nokugqitywa komphezulu oku-2, loo manyathelo acwangciswe ngokulandelelana okusisigxina kunye nexesha le-buffer elabelwe *kuphela* kwiindlela zokungaphumeleli eziqinisekisiweyo-hayi ukulibaziseka kwethiyori. I-avareji yethu yokuhanjiswa kwexesha kwii-odolo zomthamo ophakathi (i-50-500 pcs) ime kwi-98.7% kwiinyanga ezingama-22 ezidlulileyo. Umahluko we-1.3%? Zonke zilandelelwa kwiinguqu zobunjineli ezicelwe ngumthengi emva kokukhululwa kwesikhunta-kungekhona izithuba zangaphakathi.
Ukukhetha i-China metal casting factory ayikho malunga ne-geography-imalunga nokulungelelaniswa kobugcisa
I-QINGDAO QIANGSENYUAN TECHNOLOGY ayisebenzi kulo lonke ishishini. Sigxininisa kwizicelo apho ukungaphumeleli kunemiphumo yokwenyani: iivalvu zoxinzelelo lwe-hydraulic ezilawula ukunyakaza kwe-excavator boom, iiplagi ze-cobalt alloy ezitywina i-high-H2S i-gas manifolds, i-winch center shaft rollers ephakamisa izixhobo ezingaphantsi kolwandle kubunzulu bamanzi obuziimitha ezingama-3,000. Olo gxininiso luqhuba yonke into-ukusuka kumboneleli wethu wezinto eziphathekayo (siphicotha iilogi zokulinganisa iziko rhoqo ngekota) ukuya kukhetho lwethu lophando lweCMM (Renishaw PH20 kunye ne-5-axis scanning for complex impeller contours).
Ukuba iprojekthi yakho elandelayo ifuna i-microstructure ephindaphindwayo kwi-cobalt-based castings, i-GD&T-ethobelana noomatshini bomgangatho oqinileyo, okanye ukulandeleka okugcweleyo ukuya kwindawo yobushushu-kwaye uyayifuna ukuba iziswe ngaphandle kobunjineli bokuqhuba umlilo-ke ilungelo China metal casting factory ayinguye oneziqinisekiso ezininzi eludongeni. Yiyo ephethe umzobo wakho njengento esebenzayo, kungekhona umsebenzi wejometri. Liqabane elibuza *indlela* inxalenye elayisha ngayo, *apho* itywina khona, kwaye *kwenzeka ntoni ukuba iyasilela *—ngaphambi kokucaphula isenti enye.
