Kana mainjiniya emuchadenga achida turbine blades, mafuta emafuta, kana actuator housings inobata ± 0.02 mm tolerances pasi pe800 ° C thermal cycling uye 15,000 psi hydraulic mitoro-havagadzirire "zvakanaka zvakakwana" kukanda. Vanoenda kune Aerospace investment kukanda fekitari neyakasimbiswa metallurgical discipline, kwete kungogona kugadzira mold.
Ndosaka zvikwata zvekugadzira muNorth America neEurope zvichigara zvichitumira GD&T-rich dhizaini yecobalt-nickel pombi zvikamu zvakananga kuQingdao Qiangsenyuan Technology Co., Ltd.-kwete nekuti ndiyo yakachipa sarudzo, asi nekuti yayo cheni inobvisa iyo inonyanya kutadza mapoinzi: micro-shrinkage mutete-walled mativi, carbide kupatsanurwa, kupatsanurwa kwecarbide 53m dhizaini yeMS7 kupatsanurwa kwekupisa uye kupatsanurwa kweMS7. uye yekupedzisira machining.
Hapana madhirigi maviri emuchadenga anoita zvakafanana - saka fekitari haifanirewo kudaro
Takaona mapurojekiti akawandisa achinonoka nekusaenderana tarisiro: mutengesi achitora "investment casting" achimhanyisa sand-cast tooling; imwe inosimbisa "AMS 5387 inoenderana" isina batch-chaiyo spectrographic mishumo; chetatu akabata CMM data chete yekutanga-chinyorwa chekuongorora-kwete yese yakawanda. KuQingdao Qiangsenyuan, mhinduro inotanga nekuteedzera kwezvinhu-kwete zvekushambadzira.
Yese T800 cobalt-based alloy ingot inosvika ine mill test mishumo, yakazara makemikari reanalysis pa-saiti, uye thermal nhoroondo matanda akasungirirwa kune umwe neumwe kupisa. Izvi zvinoreva kuti kana mutengi anoodha 42 cobalt alloy nozzles ye-high-pressure fuel metering system, chigadziro hachingodurure simbi-inomepu yezviyo inotarisana nekuyerera mumusangano wewax pattern, inogadzirisa tembiricha yepreheat pahupamhi hwechikamu, uye inobata nguva yekusimba mukati me ± 90 masekonzi ekufananidza kubuda.
Izvi hazvisi dzidziso. Mune imwe purojekiti ichangoburwa yeEuropean hydraulic actuator OEM, takabata 0.035 mm kukobvu kwemadziro mune wax master * pamberi * ceramic shell dipping — tichishandisa optical contour scanning pachinzvimbo chemanual calipers. Izvo zvakachengetedza mavhiki matatu ekugadzirisa zvakare uye zvakabvisa zvimedu kubva mukutanga 17 castings.
Vertical kubatanidzwa haisi buzzword-ndiyo chete nzira yekudzora microstructure kutendeseka
Vazhinji vatengesi vanopa kunze kupedzisa, kupisa kurapwa, kana kunyange yekupedzisira machining. Izvo zvinotyora kuzvidavirira-uye zvinounza zvisingadzoreki zvakasiyana. Mushandi wehuni yekupisa mune imwe nzvimbo inogona kukwira pa5 ° C / min; imwe pa12°C/min. Ose ari maviri anosangana ne "AMS 2750E Kirasi 2" pabepa-asi imwe chete inoburitsa isingachinjiki yekupararira kwemvura mune cobalt-nickel alloys.
Qingdao Qiangsenyuan inomhanya nhanho dzese dzakakosha pasi pedenga reISO-rinoenderana nedenga: kukanda mari, akawanda-axis CNC machining (kusanganisira 5-axis panguva imwe chete contouring), vacuum kupisa kurapwa, uye kupera kwepasi senge electropolishing kana HVOF coating. Hapana handoffs. Hapana mikaha yedata. Kwete "akataura / akati" panguva yekuongorora-chikonzero chekuongorora.
Zvakaguma nei? Piston pombi silinda dzimba dzinopfuura 100% kudzvanywa kuyedzwa pa1.5 × kushanda kumanikidza-ine zero inodonhedza pazvikamu mazana maviri negumi nembiri mukumhanya kwepakati-vhoriyamu. Sei? Nekuti chikwata chimwechete chakasimbisa dhizaini yegeji zvakare chakasimbisa iyo yekupedzisira ID yepasi roughness (Ra ≤ 0.4 µm) uye yakasimbisa kuomarara kugovera (HRC 42–46) mukati mebore kureba kwese-kwete chete pamatatu emuenzaniso mapoinzi.
Izvo hazvisi zvekukanda zvikamu- ndezvekukodzera kuita basa
Mamwe mafekitori ekudyara mari mumhepo anobata GD&T sekushongedza. Qingdao Qiangsenyuan anoitora sechibvumirano. Kana dhirowa richida kushivirira kwechinzvimbo cheØ0.05 mm pamaburi matanhatu ane hukama nendege yedatum yakagadzirwa mushure mekukanda, pasi rechitoro rinoshandisa muchina wekuyeresa une 0.001 mm resolution-uye inorekodha kuverenga kwese mudura rakachengeteka rakabatana nenhamba yekupisa yechikamu.
Iyo nhanho yekuomarara inonyanya kukoshesa uko geometry inosangana nebasa: winch centre shaft rollers yemotokari dzeinjiniya inofanirwa kutenderera ichokwadi mukati me0.01 mm yakazara chiratidzo chekuverenga (TIR) pasi pemutoro une simba. Mavharuvhu ekudzvanya anoda kubvinza-isina chisimbiso nzvimbo nepamusoro pekupedzisira inoenderana neiyo elastomer's compression set profile. Izvi hazvisi "zvakanaka-kuva-vane." Iwo anopfuura / anokundikana maitiro akaiswa mune yega yega yekuongorora protocol.
Vatengi vanotiudza izvi zvinoita kuti ongororo yeinjiniya ikurumidze - kwete kunonoka. Imwe yekuNorth America inogadzira pombi yakacheka dhizaini yayo iteration kutenderera kubva pamazuva gumi nerimwe kuenda kumazuva matatu neshanu mushure mekuchinja kuQingdao Qiangsenyuan yekutanga kugadzira mhinduro: chaiyo-nguva GD&T kududzira, kushivirira stack-up modhi, uye mamwe mazano ezvinyorwa zvinoenderana nechaiyo-mumba-yekupisa-kubata mhinduro curves-kwete generic madatabase.
Kutarisa kumberi: mahybrid maitiro, kwete kungokanda
Muganhu unotevera hausi hombe hombe kana kukurumidza maCMM. Yakasimba fusion pakati pekukanda uye machining-kunyanya kune yakaoma yemukati geometries hazvigoneke kuwana kuburikidza nechero nzira chete. Isu tave kugadzira hybrid workflows uko investimendi-yakakandwa padhuze-mambure maumbirwo anokwenenzverwa EDM yekuchera * pamberi * yekupedzisira CNC milling-inogonesa kutonhora nzira mukati meturbine housings ine 0.3 mm mudhuri ukobvu uye 12:1 aspect ratios.
Izvi zvinoda kubatana kwakadzama kweR&D-kwete chete nevatengi, asi nevanodyidzana nesainzi. Parizvino, basa redu rekusimudzira rakabatana rinotarisa kukwenenzvera nzira dzekusimba dzeyakaderera-sigma-chikamu T800 akasiyana, kuderedza post-cast mhinduro annealing nguva ne37% pasina kukanganisa creep kuramba.
Kana chikamu chako chinotevera chemuchadenga chichida zvinopfuura kurongeka kwedimensional - kana ichida fungidziro yemetallurgical maitiro, kuteedzera kuzere, uye zero kushivirira kune process Drift - iwe unoda Aerospace investment kukanda fekitari yakavakirwa kumishoni-yakakosha kuurayiwa. Kwete volume. Kwete kumhanya. Chokwadi.
