Kana mainjiniya akatsanangura zvikamu zvearuminiyamu zve hydraulic manifolds, pombi dzimba, kana mavharuvhu ekumanikidza, kugadzikana kwedimensional uye microstructural consistency hazvisarudzike - hazvigone kutaurirana. Ndosaka mamwe maNorth America neEuropean OEMs zvino anobva a yakarasika aruminiyamu yekukanda fekitari iyo inobata kukanda kwekudyara kwete seyakamira yega, asi seyekutanga nhanho chaiyo mukufambiswa kwakanyatsodzorwa hybrid workflow. Takaona vatengi vachidzoka katatu-kutanga kune prototypes, yechipiri kune yepakati-batch kusimbiswa, yechitatu ye-yakazara-yakatevedzana kugadzirwa-nekuti vatengesi vavo vekare vaisagona kubata ± 0.05 mm pane dzakatetepa-yakavezwa aluminium flanges mushure mekupisa kurapwa. Chikonzero chikuru? Mukana pakati pehunyanzvi hwekukanda uye post-cast machining kurangwa.
Nei "Yarasika Wax" Yega Isingavimbisi Kurongeka-Uye Chii Chinoita
Yakarasika wax aluminium kukanda inoburitsa pedyo-net-shape geometry-asi chete kana iyo ketani yese yakagadzirwa kuti ishande kuvimbika. Panzvimbo yedu muQingdao, tinotanga neAMS 4117 kana A380 alloy billets dzakasimbiswa kuASTM B179, tozoona chimiro chezviyo kuburikidza nemetallographic sampling pamberi pehoko mold kusangana. Zvine hutsinye, isu hatibudise wax patani yekushandisa: yedu-mu-CNC-yakagadzirwa aluminium masters inotitendera kugadzirisa maekiseni ekudhirowa uye nzvimbo dzekugezera mukati me 0.02 mm-yakakosha pakukanda silinda dzimba dzine mukati mekutonhodza nzira pasi pe2.5 mm madziro ukobvu.
Isu takaona kuti 70% yedimensional kudonha mualuminium investment castings inoitika panguva ye de-waxing uye kupera simba-kwete kudurura. Yedu programmable kilns ramp pa 0.8°C/min kusvika 1050°C, inobata kwemaminetsi makumi mapfumbamwe kuti ibvise wakisi yasara pasina kutsemura silica-alumina shells. Kudzora ikoko kunonyanya kukosha kune zvikamu zvakaita sepiston pombi cylinder housings, uko kupisa kunotyisa panguva yekupisa kunogadzira madiki madiki anozopararira pasi pekumanikidzwa kwecyclic.
Kusiyana nezvitoro zvekukandira jecha zvinobata aruminiyamu se "nyore kudururwa," isu tinotarisisa tembiricha yekunyunguduka mukati me ± 3 ° C tichishandisa dual thermocouple immersion probes - uye tinoramba chero batch iyo hydrogen yemukati inodarika 0.12 ml / 100g (inoyerwa ne vacuum solidification test). Uku hakusi kuwandisa; ndiwo mawaniro atinoita simba rekusimba ≥310 MPa muT6-yakarapwa A380 dzimba tichichengetedza kureba> 3.5%.
Iko Kunopera Kukandira uye Injiniya Chaiyo Inotanga
Heino izvo zvakanyanya yakarasika aruminiyamu yekukanda fekitari zvinyorwa hazvikuudze: kurongeka kwekudyara kwekudyara kunodzikira nekukurumidza kupfuura 300 mm mune chero chidimbu chimwe chete. Ndosaka yedu CNC cell inogara mita kubva pamutsetse wekukanda-kwete mhiri kweimba yekuchengetera zvinhu. Isu tinochina nzvimbo dzakakosha dzekuisa chisimbiso, maburi ekukwira, uye kutakura zviboora mukati memaawa mana ekuzunza, tichideredza kuzorora kwekushushikana mualuminium matrix.
Isu tinoshandisa mashanu-axis panguva imwe chete machining ezvikamu zvakaita sewinch centre shaft rollers, uko concentricity pakati pe120 mm OD magazine uye 65 mm ID bore inofanirwa kubata 0.015 mm yakazara chiratidzo kuverenga. Hapana post-machining kupisa kurapwa kunoshandiswa kunze kwekunge kwataurwa-nokuti kupisazve kunovhiringidza iyo yakanaka-grained pamusoro pedhiri inoumbwa panguva inodzorwa kusimba. Pane kudaro, isu tinoshandisa vibratory stress relief kwemaminetsi makumi matatu pamberi pekupedzisira CMM kuongororwa.
Yedu yekuongorora protocol haisi yekutarisa-inofambiswa-inofambiswa nebasa. Kune mavharuvhu ekumanikidza, isu tinosimbisa kwete chete GD&T callouts asi chaiyo chigaro kudonha mitengo inopesana ne ISO 5208 Kirasi A zviyero. Chese chikamu chinotakura traceability label inobatanidza serial nhamba yayo kune yakaomeswa macerts, matanda echoto, CMM mishumo, uye helium leak bvunzo data.
Kana Cobalt Alloys Inopinda Mufananidzo-Uye Nei Aluminium Ichiri Kutungamira
Vamwe vanofunga kuti cobalt-nickel zvikamu zvinoreva kusiya aluminium. Kwete pano. Isu tinogara tichikandira aluminium dzimba dzinobatanidza cobalt alloy nozzles (AMS 5387) kuburikidza nekunyatso kudzvanya-kukodzera-yakasimbiswa ne ultrasonic bond test. Muviri wealuminium unobata maitiro ekugadzirisa; iyo cobalt inopinza inodzivisa kukukurwa pa 220 ° C tembiricha yemvura. Iyi nzira yakasanganiswa inoderedza mutengo ne38% maringe nemonolithic cobalt casting uchisangana neAPI RP 14E velocity limits.
Takavaka 17 iterations ye-non-standard T800-based pump plunger guide ring-imwe neimwe yakacheneswa zvichienderana nekutadza kwemunda kuongororwa kubva kumahombekombe emafuta emahombekombe. Asi izvo zvidzidzo zvakanatsiridza nzira yedu yekukanda aluminium: kusimba kwekudzora kwepakati pedendritic spacing kwakaderedza porosity muA380 mavharuvhu miviri yakavhurika kune H₂S-yakaremerwa zvinwiwa. Hunyanzvi hwezvinhu hahuna kucheneswa - hwakachinjika.
Yedu yakaonda kugadzirwa kuronga inovimbisa prototype yekutungamira nguva inogara pasi pemazuva makumi maviri nerimwe-kunyangwe kune yakaoma geometries inoda tsika ceramic cores. Kune mavhoriyamu maodha, isu tinochengetedza buffer stock yeakajairwa alloys uye shell zvinhu, saka kuteedzera kwezvinhu hakuite bhodhoro rekutakura.
Kusarudza Wokuroorana Naye, Kwete Chete Mutengesi
Kana purojekiti yako inotevera yekukanda aluminium inosanganisira madziro matete, nzira dzemukati, kana kushivirira kwakasimba pamichina maficha, bvunza mibvunzo iyi usati wasaina PO:
- Unogona here kuratidza CMM mishumo inoratidza se-yakakandwa flatness pane 150 × 150 mm flange pamusoro?
- Iwe unoita ongororo yehydrogen pane yega yega yakanyungudika-kana chete vhiki?
- Yako CNC programming yakaitwa mukati-mumba, kana kuendeswa kune mumwe mutengesi?
- Ndeipi yako yakanyorwa maitiro ekuona epakati shanduko muzvikamu zvisina nhanho?
