Apo mainjiniya anotsanangura shell molding kukanda fekitari masevhisi emhando yepamusoro-yesimbi simbi, ivo havasi kungotenga maitiro-vari kuchengetedza dimensional kudzokorora, microstructural control, uye kuvimbika kwekushanda pasi pekumanikidzwa. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., takakanda pamusoro pedzimba dzepombi dzecobalt-alloy dzinopfuura zviuru gumi nembiri kubva muna 2019-imwe neimwe inobata ±0.05 mm GD&T kushivirira patembiricha ye800°C. Iyoyo haisi iyo theoretical kugona. Ndizvo zvinoitika kana kuumbwa kwegoko kusingabatwe senhanho yakamira-asi sechiito chekutanga mune yakanyatsobatanidzwa yekukanda-machining-yekupisa kurapwa kutevedzana.
Sei Shell Molding Inoendesa Kupi Jecha Kukandwa Kunowira Pfupi
Kuumba Shell haisi "imwe nzira yekukanda." Ndiyo yega iri padhuze-net-shape maitiro ayo anogara achiburitsa pamusoro pekupedzisira pazasi peRa 3.2 µm *uye* metallurgical kuenderana pazvikamu zvakatetepa-zvakakomberedzwa pasi pe6 mm. Isu tinoona izvi zuva nezuva: hydraulic valve body ine 3.8 mm mudhuri ukobvu, gumi nemaviri emukati ekutonhodza nzira, uye AMS 5387 cobalt alloy chemistry. Kukandira jecha kunokundikana pano-kwete pamutengo, asi pane oxide inclusion njodzi uye core shift panguva yekudira. Shell molding inogadzirisa zvese. Iyo phenolic resin-bonded silica sand shell inogadzika zvakasimba pa230 ° C, inobata geometry kuburikidza ne1,420 ° C yekudurura tembiricha, uye inopisa kunze zvakachena-kusiya zero zvakasara munzira dzakakosha dzinoyerera.
Isu takazviyera: shell-yakaumbwa T800 alloy zvikamu zvinoratidza 22% yakaderera porosity pane yakaenzana jecha-yakakanda mijenya-yakasimbiswa neindasitiri CT scanning isati yagadzirwa. Izvozvo zvinoshandura zvakananga kuneta hupenyu. Mumwe mutengi wemidziyo yemafuta ekuNorth America akawedzera nguva dzebasa repombi kubva pa4,200 kusvika pa7,800 maawa ekushanda mushure mekuchinjira kudzimba dzedu dzakaumbwa nemasilinda. Hapana shanduko yekugadzira. Zviri nani kutanga zvinhu.
Vertical Kubatanidzwa Haisi Buzzword-Iyo Njodzi Yako Kuderedza
Vamwe vatengesi vanoregedzera mabhomba-akaumbwa castings kune vechitatu-bato machinists. Isu hatidaro. Chese checobalt-nickel chikamu chinosimuka kubva kune yedu ISO 9001-yakasimbiswa goko rekuumba mutsara yakananga kune yedu 5-axis CNC maseru-hapana ekunze zvinhu, hapana kudzoreredza kusavimbika, hapana batch-to-batch yekupisa nhoroondo kusawirirana. Kuenderera mberi ikoko kunonyanya kukosha pazvikamu zvakaita sepiston pombi yepakati shaft rollers: yakaomeswa kune HRC 58–62 *mushure me* machining, kwete kare. Kana kurapwa kwekupisa kwakaitika pre-machining, kusarira kushushikana kwaizotenderedza iyo 0.015 mm yechokwadi chinzvimbo kushivirira pane inotakura bhuku. Kutevedzana kwedu kunonzvenga izvozvo zvachose.
Isu tinoteedza ese akawanda: raw material mill test mishumo, shell cure cycle matanda, kudurura tembiricha curves, post-cast ultrasonic inspection results, uye yekupedzisira CMM mishumo-ese akabatana mune imwe traceability dashboard. Kana European OEM yakakumbira kuzara kwezvinhu pedigree pane AMS 5387 nozzle odha, takaendesa gumi nemanomwe magwaro akasainwa mukati memaawa makumi mana nemasere. Kwete nekuti isu tinounganidza mapepa-asi nekuti iyo data inoyerera kubva kune sensor kuenda kune system munguva chaiyo.
Miganhu Yepasi Pose—uye Mashandiro Atinoita Mairi
Shell molding ine miganhu. Inonetsekana nezvikamu zvinopfuura makumi mashanu makirogiramu kana jiometri inoda undercuts yakadzika kupfuura 15 ° isina collapsible cores. Vamwe vanogona kupokana kuisa mari kukanda kunobata izvo zviri nani. Asi kukanda kwekudyara hakugone kuenderana nekupinda kwedu pane yepakati-vhoriyamu inomhanya (50-500 pcs / mwedzi) yakaoma yakaoma simbi castings-kunyanya apo vatengi vanoda mashandiro ekuyedza pazvikamu zvitatu zvekutanga. Yedu goko rekuumba mutsara inomhanya maawa makumi maviri nemaviri / zuva, inoshandura midziyo mukati memaminitsi gumi nemasere, uye inosimbisa cavity geometry nelaser scanning isati yadirwa yekutanga.
Isu tinodzivirirawo zvipingamupinyi zvakajairika: kushandisa jecha rakadzokororwa mumisanganiswa yemagoko (tinobva silika yakasanganiswa), kusvetuka kusati kwapisa pamasimbi makuru esimbi (tinokwidza tembiricha yechoto pa45°C/awa kudzivirira kuvhunduka kwekupisa), kana kusvetuka kuzorora mushure mekukanda kushushikana padzimba dzisina tsvina (tinobata pa620°C kwemaawa mana, tobva taita mhepo-cool). Aya haasi "akanakisa maitiro." Iwo matanho asingagone kutaurirana akabikwa mumirayiridzo yebasa redu-nekuti takaona mapeji achiumba kana chero munhu akasvetuka.
Zvaunonyatsowana—Kwete Zvakavimbiswa paBhurocha
Iwe unowana kugadzikana kwedimensional: magoko-akaumbwa simbi anokandwa ku ± 0.12 mm pane maficha anosvika 320 mm kureba, akasimbiswa neZeiss CONTURA G2 CMMs akakwenenzverwa svondo rega rega. Iwe unowana kufungidzira kwemetallurgical: yega yega T800 alloy batch yakaedzwa cobalt, chromium, tungsten, uye kabhoni zvemukati-mukati me ± 0.03% ye spec-uchishandisa OES spectrometry. Iwe unowana chirango chekutumira: 94.7% pa-nguva chiyero cheiyo prototype maodha, 98.2% yekuburitswa kwekugadzirwa-inotevedzwa kuburikidza nehupenyu ERP dashboards akagovaniswa nevatengi.
Uye iwe unowana mubatanidzwa weinjiniya-kwete kutora mashoko. Kana mugadziri wepombi wekuSoutheast Asia akatitumira mufananidzo une 0.005 mm flatness callout pane 280 mm × 180 mm inokwira flange, isu hatina kuti "hongu" kana "kwete." Isu takamhanyisa kupisa kwekukanganisa modhi, takaronga yakagadziridzwa gating dhizaini, uye isu takakurudzira machini eflange * mushure me* kunyaradza kushushikana-kwete kare. Mhedzisiro? Chekutanga-chinyorwa kupasa mwero wasvetuka kubva pa62% kusvika 99%. Ndiwo mutsauko pakati pemutengesi uye yekuwedzera tekinoroji yechikwata chako.
Kana uchida a shell molding kukanda fekitari iyo inobata chaiyo sefizikisi - kwete kushambadzira - takagadzirira kumhanyisa yako inotevera yakawanda. Kwete nezvipikirwa. Iine mashizha ekugadzirisa, mishumo yekuongorora, uye dimensional data kubva pachidimbu chekutanga.
