Xa iinjineli kunye nabaphathi bokuthengwa kwempahla befuna iinkampani zokugalela isanti ifektri, abafuni nje umthengisi-bafuna iqabane eliqinisekisa ukuzinza kwe-dimensional phantsi kwe-300-bar imithwalo ye-hydraulic, ibamba ± 0.05 mm GD & T kwimibhobho ye-cobalt alloy, kunye neenqanawa zokulahlwa kwesinyithi ezilandelekayo kunye neerekhodi ezigcweleyo zokunyanga ukushisa. Inqabile loo nto. Uninzi lwabaseki besanti baphatha izindlu zentsimbi ezingwevu ngokwenjongo jikelele-kodwa bayasilela xa becelwa ukuba baphose iindawo zempompo ye-cobalt-nickel ye-AMS 5387 ekufuneka iphile iiyure ezingama-8,000 kwindawo yerhasi emuncu.
Kutheni iSand Casting isaphumelela kwiMishini-Amacandelo abalulekileyo kuShishino
Ukugalelwa kwesanti akuphelelwa lixesha—akunakubuyiselwa kwizinto ezinkulu, ezintsonkothileyo, ezinomthamo ophantsi ukuya phakathi ophakathi apho utyalo-mali lubetha iindleko okanye ubungakanani bemida. Siye sabona abathengi betshintsha ukusuka kwi-foam elahlekileyo ukuya kwiinkqubo zesanti eluhlaza emva kokungaphumeleli kweprototype: ukuqhekeka kwe-thermal kwizindlu ze-T800 ze-alloy cylinder zathi shwaka xa ukubola komngundo kunye nexesha lokumisa lilinganiswe ku-± 2% RH. Oyena mqobo? Hayi umgca wokubumba-lulawulo lwe-metallurgical kunye nokunyaniseka kwe-post-cast. Inqanaba eliphezulu iinkampani zokugalela isanti ifektri ayigaleli nje isinyithi. Ilawula ukwakheka kweenkozo ngokusebenzisa amaxabiso okupholisa alawulwayo, iqinisekisa ubulukhuni obuncinci kuwo wonke ubungakanani becandelo, kwaye inxibelelanisa imivalo yovavanyo lokuqina kwiindawo eziyinxalenye yokwenyani-hayi nje "iisampuli ezininzi."
Izakhono ezine ezingaxoxisiyo kufuneka uziqinisekise
Ngaphambi kokuvuma nayiphi na iinkampani zokugalela isanti ifektri, sebenzisa olu luhlu lokutshekisha—ngokusekwe kuphicotho-zincwadi ali-127 olungaphumelelanga lomthengisi esiluphononongileyo:
- Ukulandeleka kwemathiriyeli ekrwada ukuya kutsho kwibhetshi yokunyibilika: Akukho "izinto eziqinisekisiweyo" izitampu ngaphandle kweengxelo zovavanyo lokusila ezibotshelelwe kwi-ID yesithando somlilo kunye nenombolo yeladle. I-cobalt-nickel alloys ifuna oku-AMS 5387 iyala i-14% yokushisa okungenayo kwi-Cr / Ni drift encinci.
- Kwinkqubo yoqinisekiso lweCMM kwiicastings ezenziwe ngoomatshini: Hayi nje uhlolo lokugqibela. Sifuna imilinganiselo yolungelelwaniso kwinqanaba lomatshini-ngaphambi konyango lobushushu-ukubamba ukugqwetheka kwangoko. Omnye umxhasi ugweme i-$ 210K kwi-scrap ngokubamba i-0.12 mm yokutshintsha kwengundoqo kwizindlu zempompo zepiston ngaphambi kokuqina.
- Ulawulo lokugqiba umphezulu weendawo zokutywina ezisebenzayo: IRa ≤ 1.6 µm kujongano lwesitulo sevalvu ayikhethi. Ifuna iiparamitha zokudubula ezifakwe kwiqashiso ngalinye-kunye nokuqinisekiswa kweprofilometer ye-optical, hayi ukujonga okubonakalayo.
- Uyilo lwepateni ye-GD&T: Ukuba iqela labo lokucaphula libuza "Yintoni i-GD & T?", Hamba. Ikhono lokwenyani lithetha ukutolika unyamezelo lwendawo kwizangqa ze-flange bolt *phambi* kokwamkelwa kwepateni-kunye nokuxela imingcipheko yokupakishwa ngokubhala.
Apho uHlanganiso oluthe nkqo luhambisa i-ROI yokwenyani
ababoneleli abaninzi outsource machining okanye unyango ubushushu. Oko kwaphula uxanduva. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ukugalela isanti, i-CNC machining, kunye nokunciphisa uxinzelelo lwenzeka phantsi kophahla oluthobelayo lwe-ISO-kunye neelebhu ze-metrology ekwabelwana ngazo kunye nezigodo ezidityanisiweyo zokungathotyelwa. Xa i-winch center shaft roller ifuna ukuphinda isetyenziselwe ngenxa yokususwa kwecarburization, iqela liyilandelele kwi-one thermocouple drift ye-furnace eyodwa-hayi ukuthengiswa kakubi. Isiphumo: Ukuguqulwa kweentsuku ezi-9 endaweni ye-22. Ugxininiso lwabo kwiindidi ezine ezingundoqo-iindawo ze-CNC zomatshini, i-cobalt-nickel components, i-iron castings, kunye ne-stainless steel castings-ithetha ukuba yonke injineli yenkqubo iphathe i-50 + yejometri efanayo. Awufumani ubunzulu obuvela kwi-generalist foundries.
Yintoni eyona nto iphambili ngabathengi behlabathi (ayiyiyo into efunwa ziincwadana)
Sivavanye ii-OEMs ze-hydraulic system ezingama-43 kulo lonke elaseJamani, eTexas, naseSingapore. Abaqhubi bezigqibo abathathu abaphezulu:
- Isantya soqinisekiso lwezinto eziphathekayo: I-78% inqatshelwe iingcaphuno ezifuna> iintsuku ze-5 zoshishino ze-MTRs-nangona ixabiso elifanelekileyo.
- Ingxelo yokuyilwa kokwenziwa kwiiyure ezingama-72: Hayi "siza kujonga umzobo wakho." I-callouts ecacileyo efana "Yehlisa ubukhulu bembambo ukusuka kwi-12 mm ukuya kwi-8 mm ukunqanda ukushwabana kwe-porosity ekudibaneni".
- Ibhetshi ukuya kwibhetshi ukungaguquguquki: ± 5 HBW ukutenxa max kwi-10 amaqashiso alandelelanayo-aqinisekisiwe ngovavanyo lweBrinell kwiindawo ezintathu ngokuphosa.
Akukho fluff yokuthengisa. Imida nje enokulinganiswa ethintela ukusilela kwintsimi.
Ukukhetha iqabane lakho elilandelayo lokuphosa isanti-Amanyathelo esenzo
Ungaqalisi ngee-RFQs. Qala ngezi ntshukumo:
- Cela iilog zabo ezintathu zokugqibela ze-cobalt alloy—hayi izishwankathelo. Jonga umahluko wexesha lokufunxa, iireyithi zerempu, kwaye ucime uzinzo lobushushu obuphakathi.
- Buza ingxelo ye-CMM malunga nezindlu zevalve yoxinzelelo lwamva nje-nee-callouts ezipheleleyo ze-GD&T ezigqunywe kwezona ndawo zilinganisiweyo. Thelekisa ukupakishwa konyamezelo kunye noguquko oluqikelelweyo.
- Qinisekisa izinga lokubuyiselwa kwesanti yabo. Abadlali abaphezulu baphinda basebenzise> i-85% yesanti eboshiweyo kunye nomswakama ozenzekelayo kunye nokulawulwa komxholo wodongwe-okubalulekileyo ukunyaniseka kwendawo ehambelanayo kwiindawo eziphezulu zokugqoka.
Eyona ilungileyo iinkampani zokugalela isanti ifektri ayithembisi imfezeko. Ibhala zonke izinto ezitenxileyo, yabelane ngohlalutyo lwengcambu, kwaye yakhela emdeni kwindawo yakho yokusebenza eyona meko imbi-hayi nje imilinganiselo yelebhu yobushushu begumbi. Yiyo indlela oyeka ngayo ukuxosha izixhobo zomlilo-kwaye uqale ukuthumela iinxalenye zetsimbi ezithembekileyo.
