Akatswiri opanga zakuthambo akafuna masamba opangira turbine, ma nozzles amafuta, kapena ma actuator okhala ndi ± 0.02 mm kulolerana pansi pa 800 ° C panjinga yotentha ndi 15,000 psi hydraulic katundu - samakhazikika pakuponya "zabwino". Iwo amapita ku Azamlengalenga Investment kuponya fakitale ndi kutsimikiziridwa kwazitsulo, osati kungopanga nkhungu.
Ndicho chifukwa chake magulu opanga ku North America ndi ku Ulaya nthawi zonse amatumiza zojambula za GD & T-rich za cobalt-nickel pump parts mwachindunji ku Qingdao Qiangsenyuan Technology Co., Ltd.-osati chifukwa ndi njira yotsika mtengo kwambiri, koma chifukwa cha ndondomeko yake imachotsa mfundo zolephera zofala kwambiri: kuchepa kwazing'ono m'zigawo zopyapyala, kugawanika kwa carbide, kugawanika kwa carbide, kugawanika kwa carbide, kugawanika kwa 53m pakati pa kutentha kwa MS ndi kusiyana pakati pa kutentha kwa MS 53m7 ndi kugawanika kwa A. ndi makina omaliza.
Palibe zowulutsa ziwiri za mumlengalenga zomwe zimagwira ntchito yofanana—momwemonso fakitale sayenera kuchita
Tawona mapulojekiti ambiri akuchedwa chifukwa choyembekeza molakwika: wogulitsa akugwira mawu "kuponya ndalama" pamene akugwiritsira ntchito zida za mchenga; china chotsimikizira "AMS 5387 chikugwirizana" popanda malipoti apadera a batch; wachitatu wokhala ndi data ya CMM pongoyang'ana nkhani yoyamba - osati gawo lililonse. Ku Qingdao Qiangsenyuan, kuyankha kumayamba ndi kutsatiridwa kwa zinthu—osati zonena zamalonda.
Ingot iliyonse ya T800 cobalt-based alloy ingot imabwera ndi malipoti oyesa mphero, kusanthula kwathunthu kwamankhwala pamalopo, ndi zolemba zakale zamatenthedwe zomwe zimamangiriridwa ku kutentha kwapayekha. Izi zikutanthauza kuti kasitomala akayitanitsa ma nozzles 42 a cobalt aloyi yamagetsi othamanga kwambiri, choyambira sichimangotsanulira zitsulo - chimawonetsa momwe mbewu zimayendera motsutsana ndi njira yolowera mugulu la sera, imasintha kutentha kwa preheat pa makulidwe a gawo lililonse, ndipo imakhala ndi nthawi yolimba mkati mwa ± 90 masekondi oyerekeza.
Izi sizongoyerekeza. Mu pulojekiti ina yaposachedwa ya OEM hydraulic actuator ya ku Europe, tidachita kupatuka kwa makulidwe a 0.035 mm mu master wax * pamaso * kuviika kwa zipolopolo za ceramic-pogwiritsa ntchito makina owonera m'malo mwa ma calipers apamanja. Izi zidapulumutsa milungu itatu yokonzanso ndikuchotsa zotsalira pamasewera 17 oyamba.
Kuphatikiza kwa vertical si buzzword-ndi njira yokhayo yowongolera kukhulupirika kwa microstructure
Otsatsa ambiri amatulutsa kumaliza, chithandizo cha kutentha, kapena kukonza makina omaliza. Izi zimaphwanya kuyankha - ndikuyambitsa zosintha zosalamulirika. Wogwiritsa ntchito ng'anjo yotenthetsera m'malo amodzi amatha kutsika pa 5 ° C / min; wina pa 12 ° C / min. Onsewa amakumana ndi "AMS 2750E Class 2" papepala - koma imodzi yokha imapereka kubalalitsidwa kosasinthika mu ma aloyi a cobalt-nickel.
Qingdao Qiangsenyuan amayendetsa masitepe onse ovuta pansi pa denga limodzi logwirizana ndi ISO: kuponyera ndalama, makina a CNC amitundu yambiri (kuphatikiza ma contouring 5-olamulira nthawi imodzi), chithandizo cha kutentha kwa vacuum, ndi kumaliza pamwamba ngati zokutira za electropolishing kapena HVOF. Palibe ma handoffs. Palibe mipata ya data. Ayi "adatero / adanena" panthawi yofufuza zifukwa.
Zotsatira zake? Piston pump silinda nyumba zomwe zimadutsa 100% kuyezetsa kuthamanga kwa 1.5 × kugwira ntchito - ndi zero kutayikira kudutsa mayunitsi 212 pamayendedwe aposachedwa apakatikati. Chifukwa chiyani? Chifukwa gulu lomwelo lomwe lidatsimikizira kapangidwe ka zitseko lidatsimikiziranso kuuma kwa ID komaliza (Ra ≤ 0.4 µm) ndikutsimikizika kugawa kwamphamvu (HRC 42-46) kudutsa kutalika konseko - osati pazitsanzo zitatu zokha.
Sizokhudza kuponya magawo-ndizokhudza magwiridwe antchito oyenerera
Mafakitole ena opangira ndalama mumlengalenga amawona GD&T ngati zokongoletsera. Qingdao Qiangsenyuan amachitenga ngati mgwirizano. Chojambula chikafuna kulolerana kwa Ø0.05 mm pamabowo asanu ndi limodzi okhudzana ndi ndege yomwe idapangidwa pambuyo poponya, malo ogulitsira amagwiritsa ntchito makina oyezera omwe ali ndi 0.001 mm resolution - ndikulemba kuwerenga kulikonse mu nkhokwe yotetezedwa yolumikizidwa ndi nambala ya kutentha kwa gawolo.
Mulingo woterewu umakhala wofunika kwambiri pomwe geometry imakumana ndi ntchito: ma roller a winch center shaft amagalimoto ainjiniya amayenera kusinthasintha mowona mkati mwa 0.01 mm kuchuluka kwa chizindikiro (TIR) pansi pa katundu wamphamvu. Ma valve opanikizika amafunikira malo osindikizira opanda kutayikira okhala ndi zomaliza zofananira ndi mawonekedwe a compression a elastomer. Izi si "zabwino kukhala nazo." Ndizomwe zimadutsa / zolephera zomwe zimayikidwa mu protocol iliyonse yoyendera.
Makasitomala amatiuza kuti izi zimapangitsa kuwunika kwaukadaulo kukhala mwachangu, osati kuchedwetsa. Wopanga pampu wina waku North America adadula kamangidwe kake kuchokera pamasiku 11 mpaka masiku 3.5 atasinthira ku Qingdao Qiangsenyuan kuyankha koyambirira kopanga: kutanthauzira kwanthawi yeniyeni ya GD&T, kulolerana kwa stack-up modeling, ndi malingaliro ena azinthu kutengera ma curve enieni a m'nyumba -osati ma generic.
Kuyang'ana m'tsogolo: njira zosakanizidwa, osati kungoponya
Malire otsatirawa si ng'anjo zazikulu kapena ma CMM othamanga. Ndiko kuphatikizika kokulirapo pakati pa kuponya ndi kukonza-makamaka ma geometries ovuta amkati osatheka kutheka kudzera munjira iliyonse yokha. Tsopano tikupanga ma hybrid workflows pomwe mawonekedwe oyika ndalama pafupi ndi ukonde amabowola EDM * isanakwane* mphero yomaliza ya CNC-yothandizira njira zozizirira mkati mwa nyumba za turbine zokhala ndi makulidwe a 0.3 mm ndi 12: 1 mawonekedwe.
Izi zimafuna mgwirizano wakuya wa R&D-osati ndi makasitomala okha, koma ndi othandizana nawo asayansi. Pakalipano, ntchito yathu yachitukuko yophatikizana ikuyang'ana kwambiri kukhathamiritsa njira zolimba zamitundu yotsika ya T800, kuchepetsa nthawi ya post-cast annealing ndi 37% popanda kusokoneza kukana.
Ngati gawo lanu lotsatira lazamlengalenga likufuna kulondola mopitilira muyeso - ngati likufunika mayendedwe odziwikiratu azitsulo, kutsata kwathunthu, komanso kulolerana kwa zero pakusokonekera - muyenera Azamlengalenga Investment kuponya fakitale yopangidwira ntchito yofunika kwambiri. Osati voliyumu. Osati liwiro. Zotsimikizika.
