Xa oononjineli bechaza iintsimbi ezityhidiweyo zeevalvu zehydraulic, izindlu zempompo, okanye i-winch shafts—izinto ezimele zikwazi ukusinda kwimijikelo yoxinzelelo lweebhari ezingama-300 okanye ukuhamba kweoli enesanti—ayifuni nje mpahla. Bafuna iqabane elibone ukwaphuka okufanayo kwi-AMS 5387 cobalt alloy nozzle ku-450°C. Ngubani olinganise ukukhukuliseka kwe-microstructural kuzo zonke izifudumezi ezintlanu ze-T800-based material. Ngubani owaziyo ngokuthe ngqo apho i-porosity yokuphosa isanti ifihla khona-kwaye ukuba i-CNC igqibezela njani i-machining inokuyibeka phambi kokuhlolwa kokugqibela.
Yiyo loo nto ii-OEM zehlabathi jikelele kuMntla Melika naseYurophu zihlala zibuyela kwi- amacandelo metal ifektri iingcambu hayi kumthamo, kodwa ekuqinisekiseni: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Ikomkhulu eQingdao, le ayisiyonjongo isisiseko. Yindawo yokuvelisa echanekileyo eyakhiwe malunga nezinto ezintathu ezingenakuxoxisana-ukuphindaphinda kwe-dimensional ngaphakathi kwe-± 0.015 mm kwi-bores ebalulekileyo, ukuhambelana kwe-metallurgical kwiibhetshi, kunye nokulandelelwa ngokupheleleyo ukusuka kwisatifikethi se-billet eluhlaza ukuya kwingxelo yokugqibela ye-CMM.
Amandla abo aqala ngoqeqesho lwezinto eziphathekayo. I-cobalt-nickel alloys efana ne-AMS 5387 ayenziwanga-i-coaxed. Ukwandiswa kwe-thermal ukungalingani phakathi kwesixhobo kunye nomsebenzi, amazinga obunzima bomsebenzi ngaphezu kwe-300%, kunye nokwahlulwa kwe-carbide zonke zifuna ukulungiswa kwexesha langempela. I-QINGDAO QIANGSENYUAN ayikhupheli ngaphandle unyango lobushushu okanye ixhomekeke kumthengisi wamaphepha edatha. Endaweni yoko, badibanisa imijikelo ye-thermal kunye nabathengisi bezinto eziqinisekisiweyo, baqinisekise iqashiso ngalinye elingenayo ngokuchasene ne-ASTM E112 ubungakanani bengqolowa kunye nemigangatho ye-ASTM E381 ye-macrostructure, kwaye bagcine ukulandeleka kwenqanaba elipheleleyo le-batch-kubandakanya inombolo yokunyibilika, umhla wokugalela, kunye nezigodo zomoya womlilo. Xa umthengi ebuza "i-T800-elinganayo," impendulo ayilolwazi-luthelekiso olubhaliweyo lweeprofayili zobulukhuni, ukumelana ne-intergranular corrosion per ASTM G28, kunye nobomi be-creep rupture kwi-650 ° C.
Oku kungqongqo kunwenwela ekudityanisweni kwenkqubo. Uninzi lwababoneleli bahlula ukuphosa kunye noomatshini. I-QINGDAO QIANGSENYUAN idibanisa ngabom. Izindlu zentsimbi ezenziwe ngesanti ziye zithomalalise uxinezeleko *ngaphambi kokuba* rhabaxa i-CNC milling—kungekhona emva—kuba intsalela yoxinzelelo iyayigqwesa i-bore geometry ngexesha lokujika kokugqibela. Imilomo yotyalo-mali yecobalt ifumana ukubunjwa kwe-net-shape kunye ne-0.3 mm yesibonelelo sesitokhwe, emva koko ihambe ngokuthe ngqo kwi-5-axis machining kunye nokupholisa-nge-spindles kunye nokuhlolwa kwenkqubo. Akukho handoffs. Akukho drift ephakathi phakathi kwemisebenzi. Akukho zilophu zokuphinda zisebenze. Indawo yabo ehambelana ne-ISO iphatha ukucutheka kokuphosa, ukuphambuka komatshini, kunye nokukhula kwe-thermal njengeenguqu ezidityanisiweyo-hayi amanyathelo angawodwa. Yiloo ndlela abamba ngayo isikhundla sokwenyani kwii-callouts ze-GD&T njenge-composite positional tolerance Ø0.05 mm kwi-MMC kwiindawo ezili-12 zedatum kwi-piston pump cylinder house.
Ukuthembeka okusebenzayo kubonakala kunikezelo-hayi nje iispecs. Abathengi banika ingxelo yamaxesha okukhokela okuhambelanayo kwii-odolo zevolumu ephakathi (i-50-500 iipcs) kuba ukucwangciswa kwemveliso kusebenzisa imephu yokuhamba komsebenzi ebhityileyo, hayi uqikelelo lwekhalenda. Xa umenzi wempompo waseYurophu efuna izihlalo zevalvu ezingama-87 ze-AMS 5387 ezineejiometri ezili-17 ezizodwa, iqela laqhuba ubunjineli ngaxeshanye: ukuqinisekisa ukutolikwa kwe-GD&T kwiiyure ezingama-48, ifaka iflegi yecandelo elinodonga olucekethekileyo elityekele ekugqwethekeni ngexesha lokuvalwa kwesisombululo, kwaye licebisa uyilo oluguquliweyo lokungena olusike ukulahlwa kokulahlwa ngama-62%. Akukho “design freeze” ulibaziseko. Akukho miyalelo yokutshintsha ngomzuzu wokugqibela. Amalungu nje asebenzayo, ngexesha, kunye neerekhodi zokuhlola ezipheleleyo-kubandakanywa ne-optical contour scans ezigqunywe kwi-CAD yegama lokubonisa ukutenxa kwimephu.
Ukujonga phambili, ujoliso luyalola—alunandi. Batyala imali ye-R&D kwi-hybrid casting-machining workflows yezixhobo eziphezulu zealloy apho iindlela zemveli zibethelela imida: cinga ngemikhono engenasiphene enemikhono edibeneyo yokupholisa yangaphakathi, egqityezelwe kwisetingi enye kusetyenziswa amaziko okusila. Ukwandiswa kwesatifikethi kujoliswe kwiimfuno ezingqamene necandelo-ASME B16.34 yemibutho yevalvu, i-API 6A yezixhobo ze-wellhead, EN 15085 yezicelo zikaloliwe-hayi nje i-ISO 9001. Kodwa undoqo uhlala ungatshintshi: a amacandelo metal ifektri elilinganisa impumelelo hayi kwiitoni ezigalelwe, kodwa kwiintsilelo ze-zero kwintsimi kwiindibano ezinoxinzelelo olubalulekileyo. Ngenxa yokuba kwiinkqubo ze-hydraulic kunye neepompo ze-oilfield, ukuthembeka akuyona into. Kuphela kwengcaciso ebalulekileyo.
