Kana mainjiniya ataura kukanda kwejecha realuminium kune yakakwirira-kutendeseka hydraulic mavharuvhu kana pombi dzimba, ivo havasi kungosarudza maitiro-vari kuzvipira kudzikama pasi pemhepo inopisa bhasikoro, microstructural consistency mhiri kwe50-kg castings, uye zero kushivirira kwekudzikira porosity mumaflange anotakura. Ndicho chikonzero an aruminiyamu jecha kukanda foundry fekitari anofanira kuita zvinopfuura kudurura simbi muzviumbwa. Inofanirwa kubatanidza sainzi yesimbi nezvido zvepasi rose-kunyanya kana zvikamu zvinoshanda pa350 bar, 180°C, kana pasi pekuyerera kwematope.
Isu takaona mapurojekiti akawandisa achimira padanho reiyo prototype-kwete nekuda kwekukanganisa dhizaini, asi nekuti iyo yekutanga yakashaya chinoteedzera alloy certification, yaisakwanisa kubata ± 0.15 mm pane 420-mm cylinder bore, kana yakapotsa GD&T callouts pane yakakosha datum maficha. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kukanda jecha kwearuminiyamu yega yega kunotanga neAMS 4220 kana A380.1 verification-kwete zvitupa zveguyo chete, asi in-house spectrometric retesting isati yanyunguduka charge. Izvo hazvigone kutaurirana kana pombi yako yepiston inomisa madhora mazana maviri nemazana mana emamiriyoni ekuchera kumahombekombe.
Chii chinoparadzanisa fekitori yearuminiyamu yejecha yekukandira inowanikwa kubva kune inotengeswa? Kutanga: kutonga pamusoro peketani yakazara. Isu hatibudise core kugadzira, shakeout, kana kunyaradza kushushikana. Yedu ISO-inoenderana nzvimbo inobata pateni chitoro, mold musangano, kudurura, kupisa kurapwa (T6 kana T7 sezvakatsanangurwa), uye CNC kupedza-machining-zvese pasi pedenga rimwe. Nei izvozvo zvine basa? Nekuti 0.08 mm kusarongeka pakati pehalf mold inova 0.3 mm mudhuri-ukobvu musiyano mune 120-mm-diameter valve muviri. Uye mutsauko iwoyo unokonzeresa kuneta kusati kwasvika kuputika pane fillet radius. Isu tinoibata pane yekutanga CMM scan-kwete mushure mekutadza kwemunda.
- Dimensional kutendeka: Isu tinosimbisa cavity geometry tichishandisa Optical 3D scanning isati yagadzirwa mold-kwete chete CAD-kune-chikamu kuenzanisa, asi chaiyo jecha mold metrology.
- Microstructure kutendeseka: Batch imwe neimwe inobata metallographic analysis ye eutectic silicon morphology; yakaoma, tsono-yakaita Si inoderedza machinability uye kupfeka kuramba
- Kugadzirira kwechiso: As-cast Ra ≤ 12.5 μm panzvimbo yakakosha yekuisa chisimbiso-hapana kuputika kwechipiri kunze kwekunge kuchidikanwa pakunamira
- Kusimbisa kunoshanda: Yese yekumanikidza valve yekukanda inopfuura helium kuvuza kuyedzwa pa 1.5 × kushanda kumanikidza kusati kwatanga machining.
Vamwe vanopokana kukanda jecha hakugone kuenderana nekudyara kwekudyara kune ruzivo rwakanaka. Ichokwadi-kune maficha ari pasi pe1.2 mm, kudyara kunokunda. Asi kune yakaoma geometries senge winch centre shaft rollers ane akabatanidzwa egiya mazino, kutonhora zvimbi, uye mafuta ndima? Kukandwa kwejecha kunopa zvirinani kupisa misa kudzora panguva yekusimba, kuderedza kupisa kubvarura mumatete-chikamu mbabvu. Isu tinoshandisa resin-yakasungirirwa silica jecha ine inodzorwa permeability (120–140) uye inotonhora-bhokisi kuomesa kuti idzokororwe mumazana mazana maviri+ mold pasvondo. Hapana "one-off" setups. Hapana mutsauko wemanyorero emaoko. Ingoyerwa pneumatic compaction uye chaiyo-nguva mwando yekutarisa.
Kusarudzwa kwezvinhu hakusi dzidziso pano. Kana European OEM yaida kutsiva dzimba dzepombi yecobalt-alloy inomhanya crude yekugadzira, isu hatina kukanganisa kuA380. Isu takamhanyisa yekudziya simulation pane ese A380 neAlSi10Mg-tichibva taratidza hukuru hweAlSi10Mg hunokambaira huri pamusoro pe150 ° C hwakadzikisa kukanganiswa kwe40% pamusoro pegumi remaawa ekushanda. Ndiwo mutsauko uripo pakati pekutora chikamu uye kugadzirisa dambudziko rehurongwa. Mainjiniya edu anogara achiwongorora mishumo yeFEA nevatengi-kwete kuti vabvumire kudhirowa, asi kuti vatarise njodzi yekuisa inosimudza inogona kubata hydrogen munzvimbo inodzvanyirira chiteshi.
Kuvimbika kwekutumira kunoenderana nekufanotaura-kwete zvivimbiso. Isu tinoteedzera aluminium jecha rekukanda maodha negiredhi realloy, kwete chete zuva rakakodzera. A380 inomhanya Muvhuro-Chitatu; AlSi10Mg inowana China-Chishanu inotsvedza kudzivirira kusvibiswa. Imwe neimwe yekukanda mijenya inotakura kuzere kuteedzera: choto ID, kunyungudutsa tembiricha gidhi, yekudurura chitambi chenguva, uye siginecha yemushandisi. Kana mutengi akakumbira PPAP Level 3, tinoendesa certs, chinyorwa chekutanga CMM mishumo, tensile test data, uye radiographic mifananidzo-kwete pfupiso. Ndiwo machengetero atinoita 98.7% pa-nguva yekuendesa kwepakati-vhoriyamu inomhanya (50–500 pcs/mwedzi) mhiri kweNorth America, Germany, neSingapore.
An aruminiyamu jecha kukanda foundry fekitari inowana kuvimba kwete kuburikidza nemabhurocha, asi kuburikidza nezvinoitika kana kukanda kuchitonhora: hapana isingatarisirwe warpage, hapana-yekupedzisira-yekupedzisira rework pane datum nzvimbo, hapana kushamisa kurambwa pakuwongorora kwekupedzisira. PaQINGDAO QIANGSENYUAN TECHNOLOGY, kuwirirana ikoko kunobva mukubata mold yega yega semudziyo chaiwo-kwete zvivakwa zvinoraswa. Kubva panguva iyo aluminiyamu yakanyungudutswa yarova mold kusvika payekupedzisira inoshanda bvunzo, isu tinogadziridza mamiriro ayo chikamu chichasangana nacho-kwete chete kudhirowa.
Tichitarisa kumberi, tarisiro yedu inorodza: kusimba kwakabatana kwekukanda jecha neiyo hybrid additive tooling yepasi-vhoriyamu, yakakwirira-yakaoma cores; yakawedzera AMS 5387 kuenderana kwealuminium-cobalt hybrid magungano; uye AS9100 certification neQ4 2025. Nokuti chizvarwa chinotevera chezvikamu zvesimbi zvakanyatsorongeka hazvizotsanangurwi nekukanda chete-asi nekukanda kusina musono kunogonesa kushanda pazvinonyanya kukosha.
