Xa iinjineli zichaza a umzi-mveliso wenkonzo yokugalela isanti kwimishini yentsimbi ebaluleke kakhulu, ayenzi nje i-odolo yokuphosa-baqinisekisa ukuzinza kwe-dimensional phantsi kwe-300-bar imithwalo ye-hydraulic, ukunyaniseka kwe-microstructure emva kokunyangwa kobushushu, kunye nokunyamezela kwe-zero kwi-porosity kwi-cobalt alloy nozzles. Leyo yinyani esiyibona imihla ngemihla kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD-indawo apho ukuchithwa kwesanti kungeyona inkqubo yokubuyela umva kodwa isisombululo esichanekileyo sobunjineli bamacandelo angaphumeleli ukuba aphambuke nge-0.05 mm.
Ukwenziwa Kwesanti Okuhlangabezana neeMfuno eziSebenzayo-Hayi nje imilo
Uninzi lwabathengi bacinga ukuba ukujulwa kwesanti kuthetha ixabiso eliphantsi, umsebenzi ochanekileyo. Kodwa kwizindlu zempompo ezinoxinzelelo oluphezulu okanye iirola zeshaft yewinch ekude nonxweme, ukugalelwa kwesanti kudla ngokuba *kuphela* kwendlela esebenzayo eya kwi-net-shape geometry phambi kokuba i-CNC igqitywe—ingakumbi xa ubukhulu bodonga bungaphezu kwe-120 mm okanye imingxunya yangaphakathi ifuna ii-cores ezingenayo idrafti. Siye sabona abathengi betshintsha ukusuka kwi-investment casting ukuya kwi-santi casting emva kokuqhekeka kwenzeke ngexesha lonyango lwe-AMS 5387: izinga lokupholisa elicothayo lokungunda kwesanti eluhlaza kunciphisa uxinzelelo lwe-thermal ngama-40% kwiibhloko ze-cylinder ezisekelwe kwi-T800.
Isiseko sethu esithobela i-ISO sisebenzisa isanti ye-silica ebotshelelwe ngokwekhemikhali enobumanzi obulawulwayo kunye nomlinganiselo wokubopha—hayi “isanti efumanekayo” eqhelekileyo. Kutheni ibalulekile nje? Ngenxa yokuba ukuxinana okungahambelaniyo kukhokelela ekutshintsheni kokungunda. Kwaye utshintsho lokungunda lutshabalalisa i-GD&T callouts kwiiflange zepompo yepiston. Siqinisekisa umngundo ngamnye ngokuskena okubonakalayo phambi kokuba sigalele, emva koko silandele ulungelelwaniso loshicilelo olungundoqo sisebenzisa iindawo zereferensi ezilinganisiweyo-hayi iitshekhi ezibonakalayo.
Olu qeqesho luchaza ukuba kutheni iivalvu zethu zoxinzelelo zibamba i-ASME B16.34 i-Class 600 yokulinganisa ngaphandle kokulungiswa kwe-weld post-cast-kwaye kutheni i-OEMs yemoto yobunjineli ibuyela kwisizukulwana sesibini se-winch shafts kunye ne-specs yokuphuma eqinile kunomyalelo wokuqala.
Apho iSand Casting kunye neCNC Machining Converge
Abanye ababoneleli baphatha ukuphosa kunye noomatshini njengamasebe ahlukeneyo. Sibaphatha njengetsheyini enye yenkqubo eqhubekayo. Xa usithumelela umzobo weplagi ye-cobalt-nickel alloy, iqela lethu liphonononga uyilo lokungena *ngokulandelelana kwakho komatshini engqondweni*. Sibeka iindawo zokunyuka ukuze iiseti zokugqibela ze-CNC zithintele ukusikeka okuphazamisekileyo kwiindawo ezicuthekayo. Umatshini wedatum umphezulu *phambi* kokuphumla koxinzelelo lokugqibela-ukuze ukugqwetheka kungenzi ingxelo yakho yeCMM ingasebenzi.
Oku kudityaniswa kubaluleke kakhulu kumacandelo afana neziseko zempompo: ukujulwa kwentsimbi yecandelo elinzima elifuna i-3-axis milling kubuso obuthandathu, kunye nokugrumba umngxuma onzulu wokufaka iibholithi. Ukuba i-casting's-cast flatness idlula i-0.8 mm / m, ukugqiba umatshini kudla kwisibonelelo sesitokhwe-kunye nemingcipheko eveza i-subsurface porosity. Ke silawula ixesha le-shakeout, ukupholisa ngokufanayo kwimingxunya egqunyiweyo, kwaye siqinisekise ukuthamba kumanqanaba amathathu: njengokuphoswa, emva kokuthomalalisa uxinzelelo, kunye nokucwangciswa kwangaphambili.
Isiphumo? I-92% isivuno sokuqala sokupasa kwii-odolo ze-volume medium-akukho zi-loops zokuphinda zisebenze, akukho ukuphambuka okumangalisayo ekuhlolweni kokugqibela.
Ukulandelelwa kweMathiriyeli onokuthi uyiqinisekise-hayi nje ibango
“Izinto eziqinisekisiweyo” zithetha kancinane ngaphandle kokuba unokulandelisa kwinani lobushushu, i-melt log, kunye nengxelo yovavanyo lwe-tensile bar. Sifumana zonke i-cobalt alloys (kubandakanywa i-AMS 5387 kunye ne-T800 amabakala) ukusuka kwii-mills kunye ne-EN 10204 3.1 isatifikethi-kwaye sigcine amaxwebhu apheleleyo kuwo wonke amaqashiso: uhlalutyo lweekhemikhali, ubungakanani beenkozo kwi-ASTM E112, kunye nexabiso lempembelelo ye-Charpy kwi--40 ° C kwizicelo ze-offshore.
Asigxininisi nje "i-SS316" kwithegi. Ilaser-etch amanani obushushu kuyo yonke into efakwayo, ireferensi enqamlezileyo kwinkqubo yethu yeERP ngokuchasene neerekhodi zokuhlola ezingenayo, kwaye ibandakanya iidosi zokulandeleka ezigcweleyo kunye namaxwebhu athunyelweyo. Omnye umxhasi wezixhobo ze-oilfield yaseNyakatho yaseMelika wasebenzisa le datha ukucima uphicotho lwe-API Q1 phantsi kwemizuzu engama-45-akukho zicelo zokulandela.
Kwaye xa abathengi bebuza, "Ngaba unokuphinda ibhetshi yonyaka ophelileyo?" -Sitsala eyona nto ifanayo yesithando somlilo, ibhetshi yomxube wesanti efanayo, iqashiso elingundoqo elifanayo. Hayi "efanayo." Ngokufanayo.
Kutheni iiNjineli zeHlabathi zikhetha le Factory yeNkonzo yokuCasa isanti
Awudingi omnye umthengisi ocaphula ngokukhawuleza kwaye azise emva kwexesha. Udinga iqabane elibonisa ukungquzulana kwe-GD&T *phambi kokuba* kuqale isixhobo—njengokuchaza ukuba ukunyamezela kwe-±0.02 mm kwi-200-mm-diameter bore kufuna umatshini wesibini, hayi nje ukuphosa. Ufuna ukucaca ngexesha lokukhokela abaqhubi: i-sand mold prep ithatha iintsuku ezi-7; ukuguqulwa kwepateni yongeza i-3; I-AMS 5387 unyango lokushisa longeza i-10-kungekhona "iiveki ezi-2-4" ngaphandle kokuphazamiseka.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inika loo ngcaciso. Abaphathi beeprojekthi zethu bathetha ngobunjineli ngokutyibilikayo—hayi ijagoni yokuthenga. Baza kukuxelela ukuba kutheni umlomo wengxubevange ye-cobalt ufuna ukugcinwa kweqokobhe le-ceramic kwi-cope, okanye kutheni ukujulwa kwentsimbi engenakutyiwa ngaphezulu kwe-80 kg kufuna uncedo lwe-centrifugal kwisandi. Akukho zithembiso ezingacacanga. Ifiziksi nje, isinyithi, kunye nolawulo lwenkqubo ebhaliweyo.
Ukuba umyalelo wakho olandelayo wokuphosa isanti kufuneka wenze-ungafiki nje-qala ngokuphononongwa kobugcisa, hayi iphepha lexabiso. Umahluko ubonisa kubomi bentsimi, kungekhona nje ephepheni.
