Apo mainjiniya anotsanangura kukanda kwegiravhiti kwezvikamu zvesimbi zvakakura-kunyanya mu hydraulic masisitimu, oiri & gasi mavharuvhu, kana inorema-duty pombi dzimba - ivo havasi kungosarudza maitiro. Ivo vari kusarudza mudiwa anodzora simbi yesimbi, dimensional kudzokorora, uye kuvimbika kwekushanda kubva kune yakasvibirira alloy kusvika pakupera chikamu. Ndicho chikonzero zvikwata zvepasi rose zvekutenga zvinhu zvichiwedzera kutendeukira kune nyanzvi fekitari yekukanda giravhiti mashandiro-kwete akajairwa ekutanga-aine vertically akabatanidza hunyanzvi, yakanyorwa traceability, uye yakasimbiswa ruzivo muma superalloys seAMS 5387 uye T800.
Nei Gravity Casting Ichiri Kukunda yeMishoni-Yakakosha Maindasitiri Zvikamu
Gravity casting haisati yapera. Inosarudzwa nemaune kana iwe uchida dense, yakaderera-porosity castings ine yakaomesesa mejini yekudzora zvivakwa-kunyanya kune zvikamu zvinopinda cyclic pressure mitoro kana abrasive kupfeka. Kusiyana ne-high-pressure die casting, simbi yakanyungudutswa-giravhiti inopinda muforoma zvishoma nezvishoma, ichideredza kusagadzikana uye kuvharirwa kwegasi. Zvakaguma nei? Simba repamusoro-soro, kuramba kuneta kuri nani, uye hukuru hwemachina post-cast-yakakosha kune zvikamu zvakaita sepiston pombi silinda dzimba kana miviri yekumanikidza mavharuvhu uko micro-shrinkage kana voids yemukati inogona kukonzera kutadza kwemunda.
Takaona vatengi vachichinja kubva kune dzimwe nzira dzekudyara-kasira mushure mekudzokorodza kutsemuka mucobalt-nickel nozzles inoshanda pamusoro pe450 ° C. Kukandira kwegiravhiti kwakaunza chimiro chezviyo chinodiwa-uye zvakakosha, chakabvumira kuiswa chaiko kwezvikwiriso nemafeeder kuti ive nechokwadi chekusimba. Iyo level of process control haiitiki netsaona. Zvinoda kudzika kwesimbi kungwara, makumi emakore epateni-kune-chikamu mhinduro loops, uye ISO-inoenderana nemafuta ekutarisa pakudururwa kwese.
Zvina Zvisingataurwi Zvinogona muKushanda Kwepamusoro-Kuita Gravity Casting Factory
A anokwanisa fekitari yekukanda giravhiti inofanira kuunza zvinopfuura simbi yakadururwa. Hezvino izvo zvinoparadzanisa vanogadzira-vakagadzirira vabatsiri kubva kune vanotengeserana vatengesi:
- Material mastery kupfuura magiredhi akajairwa: Haasi ese cobalt alloys anoita zvakafanana. AMS 5387 inopindura zvakasiyana kumazinga ekutonhodza pane T800-based akasiyana. Nyanzvi yechokwadi inochengetedza kudyidzana kwehunyanzvi nevashambadziri vezvinhu zvakasimbiswa-uye inosimbisa imwe neimwe yekupisa inopesana neASTM E112 (saizi yezviyo), ASTM E353 (kuongorora kemikari), uye yakatsanangurwa nevatengi tensile curves.
- Dimensional kugadzikana kune ese mahybrid maitiro: Yakawanda yepamusoro-inoshanda giravhiti castings inoda CNC machining mushure. Kana imba yekukandira isiri yavo yekugadzira machining nzvimbo-kana ichishaya GD&T-inokwanisa maCMM pasaiti-njodzi yekuwedzera kushivirira stack-up inowedzera. Isu takayera kusvika ku ± 0.12 mm kutsauka mukurongeka kwakaomarara apo kukanda uye machining zvakakamurwa kune vatengesi.
- Yakazara-batch traceability pasi kune melt log: Kune oiri & gasi kana hydraulic OEMs, "traceable" zvinoreva kuziva kuti ndeipi chaji yechoto yakaburitsa kuti ndeipi kukanda, kutenderera kwayakaitwa, uye kuti ndeupi mushandisi akasaina pakaongororwa kekupedzisira. Hapana mapepa ematanda. Hapana batch-nhamba yekufungidzira.
- Kusimbisa kunoshanda-kwete chete kutevedza kwedimensional: Imba yekumanikidza valve imba inogona kupfuura CMM cheki asi ichiri kudonha pasi pe350 bar. Mafekitori epamusoro-tier anoitisa hydrostatic kuyedza, dhayi-inopinda ongororo paASTM E165, uye kunyange prototype-level inoyerera-nzira yekuongorora isati yaburitsa ekutanga zvinyorwa.
Chii Chaiyo-Nyika Mapurojekiti Anoratidza Nezve Maitiro Ekukura
Funga nezveodha yazvino yeinjiniya mota paboard winch centre shaft rollers. Chikamu chaida 42 HRC kuoma, kupera kwepamusoro ≤Ra 0.8 µm pamajenari anotakura, uye zero mukati porosity mukati me5 mm yechigaro chekutakura. A generic foundry akataura mavhiki gumi nemaviri uye akaramba mutoro wekusiyana kwe microstructure. Mhinduro yacho yakabva kune imwe nzvimbo yaiita jecha * uye* kupisa kupisa mukati memba, yakashandisa optical emission spectroscopy pane yega yega yekudirwa, uye yakasimbisa kuomarara profiles neRockwell B/C muchinjiko-chikamu mepu. Kubvumirwa kwechinyorwa chekutanga kwakatora mazuva masere - kwete mwedzi.
Imwe nyaya yaisanganisira cobalt alloy plugs ye subsea pombi magungano. Iyo geometry yaisanganisira dzakatetepa-madziro zvikamu (2.3 mm zita) uye mukati radii diki seR0.5 mm. Madhizaini egeji akajairwa akakonzera kutonhora kusati kwasvika uye kuvharika kwechando. Mutengesi akabudirira akagadzira patsva sisitimu yekumhanya achishandisa solidification simulation software-uye akasimbisa modhi ine thermocouple-mapped tembiricha gradients panguva yekudirwa kwekuyedza. Irwo rudzi rwekudzokorodza runongoshanda chete kana mainjiniya ekukanda achigara padivi pemetallurgists uye CNC programmers zuva nezuva.
Kusarudza Mumwe Wako: Kupfuura Mabhurocha uye Zvitupa
Zvitupa zvine basa-asi zvinhu zvehutsanana, kwete vanosiyanisa. ISO 9001 ndiyo tafura yemasiteki. Chii chinofambisa tsono ihwo humbowo hwedomeini-chaiyo dambudziko-kugadzirisa: Vanoshambadza nyaya zvidzidzo pane hydraulic valve yekukanda goho kunatsiridza? Vanogona here kugovera data yekufungidzira yekupisa kubva kune yavo yekupedzisira gumi AMS 5387 inodurura? Ko yavo QC mishumo inosanganisira microstructure mapikicha-kwete chete kuoma nhamba?
Tarisa zvakare mireza matsvuku: "Saizi-imwe-inokodzera-ose" madhizaini emagedhi, kusakwanisa kubata ± 0.05 mm pane yakakandwa-mu-datum maficha, kana kuvimba nevechitatu-bato rinopisa rinopisa pasina kubatana kwemaitiro. Aya masaini akapatsanurwa kugona-kwete kunyatsobatanidzwa.
Kune mainjiniya ari kutsvaga giravhiti-akakanda zvikamu nhasi, sarudzo haisi yemutengo pakirogiramu. Zviri pamusoro pemutengo wakakwana wevaridzi: mashoma reworks, nekukurumidza NPI kutenderera, uye zero kutadza kwemunda pazvikamu zvinochengeta pombi dzichimhanya, kuvhara mavharuvhu, uye mota dzichishanda munzvimbo dzakanyanyisa. Kuvimbika ikoko kunotanga ne fekitari yekukanda giravhiti iyo inobata kudira kwese seyedzo inodzorwa-uye yega yega mutengi kudhirowa senge inoshanda yakatarwa.
