Xa iinjineli zicacisa iinkonzo zefektri ezichanekileyo, azikho nje uku-odola iinxalenye-zikhusela uzinzo lwe-dimensional phantsi kwe-300-bar imithwalo ye-hydraulic, ukunyaniseka kwe-microstructure emva kokunyangwa kobushushu, kunye nokugqitywa komphezulu ongayi kuvelisa i-cavitation kwizindlu zempompo ezinesantya esiphezulu. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphose phezu kwe-12,000 yentsimbi kunye nentsimbi engenasici kwiivalvu zoxinzelelo, izindlu ze-piston pump cylinder, kunye ne-winch center shaft rollers-nganye ibanjwe ku-± 0.05 mm GD & T ukunyamezela kwiimpawu ezibalulekileyo ze-datum. Elo nqanaba lokuphindaphinda aliveli kwisixhobo sodwa. Ivela ekulawuleni ikhonkco elipheleleyo: i-AMS 5387 cobalt alloy feedstock eqinisekisiweyo, ukubumba kwesanti okuqinisekisiweyo kunye nokulinganisa i-thermal, i-CNC machining ebhekisela kwii-datums-ezingezizo iimodeli zethiyori-kunye nokuhlolwa kwe-CMM ngaphambi nangemva kokunciphisa uxinzelelo.
Kutheni intsimbi echanekileyo ifuna ukudityaniswa okuthe nkqo-hayi nje isiseko
Uninzi lwabathengi bacinga ukuba "ukuphosa ngokuchanekileyo" kuthetha ukunyamezelana okuqinileyo. Inyani inzima ngakumbi. Isiseko sempompo yentsimbi yesanti eyi-sand-cast ye-316 inokubamba ± 0.3 mm kwijometri yobuninzi-kodwa i-flange yayo ekhwelayo kufuneka ibethe ± 0.03 mm ukuphuma *emva* konyango lobushushu kunye nomatshini wokugqibela. Kulapho amakhonkco obonelelo aqhekekileyo ahlulekayo. Umthengisi omnye uyaphosa. Abanye oomatshini. Isithathu senza i-NDT. I-handoff nganye ibeka emngciphekweni ulungelelwaniso olugwenxa, utshintsho lwedatum, okanye ii-microcracks ezingaxelwanga.
Siqhuba zombini utyalo-mali kunye nemigca yokuphosa isanti *ngaphakathi kwendawo efanayo ye-ISO 9001* apho iiseli zethu ze-CNC ze-5-axis zisebenza khona. Xa umthengi ethumela umzobo we-T800 cobalt alloy nozzle, iinjineli zethu zenkqubo ziyayiphonononga *phambi kokucaphula*: Ngaba ubukhulu bodonga banele ukunqanda ukukrazuka okushushu ngexesha lokuqina? Ngaba i-engile eyidrafti ivumela ukukhutshwa kokungunda okucocekileyo ngaphandle kokusila kwangemva kokuphoswa okuya kubeka esichengeni umphezulu onganyangekiyo kukutya? Ngaba indawo inokulungiswa kumatshini yonke imiphezulu esebenzayo kwiseto enye-ukususa impazamo eyongezelekayo?
Oku akuyothiyori. Kunyaka ophelileyo, i-OEM ye-hydraulics yaseYurophu isithumelele idizayini ehlaziyiweyo yomzimba wevalve enembambo yangaphakathi eyi-2.5 mm. Iqela lethu labasunguli liyiphawule njengento ethanda ukushwabana i-porosity. Sicebise ushicilelo olungundoqo lwendawo kwaye sahlengahlengisa inkqubo yokungena. Isiphumo: i-zero scrap kwiiyunithi ezingama-420, ngokuchasene ne-27% yokukhatywa kumboneleli wabo wangaphambili.
Iindleko zokwenyani zokuthi "Yiphose nje"-Kwaye kutheni ukulandelelwa kweMathiriyeli kungenakuzikhethela
Ezinye izicatshulwa zefektri ezichanekileyo zokuphosa zikhangeleka zinyanzelekile-ude ubone ii-certs eziphathekayo. Sifuna iingxelo zovavanyo lokusila (MTRs) kulo lonke ubushushu, olufakwe kwiinombolo zebhetshi kwi-ERP yethu. Xa umthengi echaza i-AMS 5387 yeplagi yobushushu obuphezulu, siye salanda ingot ekrwada sibuyela kwivacuum arc remelt furnace eJamani-hayi nje amaphepha osasazo. Ngoba? Ngenxa yokuba i-cobalt-nickel alloys iphila okanye ifa ngokusasazwa kwe-carbide. Ukutenxa nge-5°C kwisinyibiliko sobushushu bobushushu butshintsha ubulukhuni nge-8 HRB. Ngaphandle kwekhemistri elandelekayo kunye nembali yobushushu, ungcakaza kubomi bokudinwa.
Sikwakhaba iindlela ezimfutshane "zebakala eliqhelekileyo". Ukuba indlu yakho yempompo ibona ukulayisha okujikelezayo ngaphezu kwe-150 MPa, i-304 engenasici ayiyi kuyinqumla-kungakhathaliseki ukuba iphoswe kakuhle kangakanani. Asigqibekanga kwi-ASTM A743 CF8M okanye i-custom-modified 17-4PH kunye nokuguga kwe-H1150, kuxhomekeke kwimeko yoxinzelelo kunye nokuhambelana kwamanzi. Olo qeqesho luxabisa i-12-18% ngaphezulu kwasekuqaleni. Kodwa iphelisa ukungaphumeleli kwentsimi ebiza i-30 × ngaphezulu ngexesha lokuphumla, amabango ewaranti, kunye nomonakalo wegama.
Eyona nto yenzekayo phakathi komzobo wakho kunye nokuhanjiswa
Umsebenzi wethu awuhambelani-iyaphindwa:
- Iveki yoku-1: Uqinisekiso lwe-GD&T + ingxelo yokwenziwa. Sifaka iflegi yeempawu ezinje ngodonga olucekethekileyo lwerediya engaphantsi kwe-0.8 mm okanye imingxuma eyimfama enzulu kuno-8× ubukhulu-emva koko sicebisa ezinye iindlela ezigcina umsebenzi kodwa zicuthe ixesha lomjikelo ngama-35%.
- Iveki 2–3: Ukwenziwa komngundo + ukubunjwa kwenqaku lokuqala. Sithumela imifanekiso yeradiyografi kunye nohlalutyo lweekhemikhali-hayi nje iingxelo ezinobungakanani.
- Iveki 4: Umatshini nge-in-process CMM iitshekhi kuwo wonke umsebenzi. Akukho "uhlolo lokugqibela kuphela."
- Iveki 5: Uvavanyo lokugqibela olusebenzayo: uvavanyo lokubola koxinzelelo ukuya kuthi ga kwi-400 bar, ukuqinisekiswa koburhabaxa bomphezulu nge-ISO 4287 nganye, kunye namaxwebhu agcweleyo okulandeleka kwezinto.
Sithumela iiprototypes kwiintsuku ze-18. Ii-odolo zomthamo ophakathi (i-50-500 iipcs) zihambisa kwiiveki ezi-6-8-kunye neentsuku eziqinileyo zivaliwe ngokubhaliweyo, kungekhona uqikelelo lwe-imeyile.
I-Steel Precision Casting Factory ithetha iNtsebenziswano yobuNjineli-hayi nje iMveliso
Ukuba ufuna imveliso yentsimbi echanekileyo ephethe umzobo wakho njengekhontrakthi-kungekhona isiphakamiso-uya kufumana ulungelelwaniso kwi-QINGDAO QIANGSENYUAN. Asisukeli umthamo wexabiso eliphantsi. Sisombulula iindlela zokungaphumeleli: ukhukuliseko kwimibhobho ye-cobalt alloy, ukugalela kwizikhondo zevalve yentsimbi engenasici, ukugqwetheka kwintsimbi yecandelo elikhulu emva komatshini.
Inyathelo lethu elilandelayo kukuqinisekisa ukuya ku-AS9100 ngokujulwa kwentsimbi ye-aerospace-grade kunye nokwandisa i-hybrid casting-machining cell for kufuphi-net-shape superalloy components. Kodwa ixabiso lanamhlanje alikho kwizicwangciso ezizayo-ku-99.2% isivuno sokuqala sokupasa kwi-AMS 5387 iinxalenye zepompo, i-0.02 mm flatness kwi-400-mm-diameter ye-stainless steel flanges, kunye nenyaniso yokuba i-73% yabathengi bethu abaphindayo basisebenzise iminyaka engaphezu kwemihlanu.
Xa ukuchaneka kwe-dimensional, ukuthembeka kwezinto eziphathekayo, kunye nokuqiniseka kokunikezelwa akunakuthetha-qala nge-steel precision casting factory elinganisa impumelelo kwii-microns, kungekhona imida.
