Kana mainjiniya ataura zvikamu zvealuminium zve hydraulic manifolds, pombi dzimba, kana masisitimu emagetsi emotokari, havawanzotanga ne "jecha rekukanda." Vanotanga nedambudziko: kukwira bhasikoro, kushivirira kwakasimba kweGD&T, kudzvanya kuvimbika pa350+ bar-uye zero margin ye micro-porosity kana dimensional drift. Ndipo pano a jecha rinokanda aluminium fekitari inomira kuva mutengesi uye inova dhizaini yekuwedzera. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Takaona kutadza kunoramba kuripo katatu mumapurojekiti ekukanda jecha realuminium-kwete kubva kutsika dzisina kunaka, asi kubva kune tarisiro isina kurongeka painjiniya handoff.
Kutanga: kutora "aluminium" zvinoreva A380. Hazvidaro. Muchitoro chedu, 75% yearuminiyamu jecha castings inomhanya paA383 kana yakasarudzika-yakagadziridzwa 319 akasiyana-kunyanya kune yakagadziridzwa fluidity mumatete-madziro pombi nheyo uye nani machinability mushure mekupisa T6 kurapwa. Chechipiri: yakatarisa mold jecha kugoverwa kwezviyo. Isu tinoshandisa resin-bonded silica ine inodzorwa 45-75 µm gradation-kwete nekuti iri mwero, asi nekuti inocheka kushata kwepamusoro (Ra) ne30% kupesana nejecha regirinhi rekare, kuderedza post-cast yekukuya nguva pamasilinda edzimba flanges. Chechitatu: kusvetuka pre-cast FEA simulation yekusimbisa shrinkage. Mumwe mutengi wekuNorth America akatitumira piston pombi yedzimba yekudhirowa ine 22 mm gobvu mbabvu iri padhuze nemadziro matanhatu. Simulation yakaratidza nzvimbo ine njodzi yakanyanya. Isu takaronga kuisirwa kutonhora kwenzvimbo - uye takabvisa 100% yemukati shrink cavities iyo yakatadza yavo yekutanga X-ray batch.
Chii chinoparadzanisa anokwanisa jecha rinokanda aluminium fekitari kubva kune iyo inopa mishoni-yakakosha zvikamu? Vertical kubatanidzwa-kwete chete kukanda, asi iyo yakazara cheni kubva kune alloy kusarudzwa kune inoshanda kusimbiswa. Isu tinongopa yakasimbiswa aluminium ingots ine yakazara mill test mishumo (ASTM B179, EN 1706), tobva taita OES ongororo pabatch yega yega yakanyungudika. Hapana kunze. Yedu CNC machining maseru anogara metres kubva pachiteshi che shakeout-saka castings inofamba yakananga mukugadzirisa pasina tembiricha-induced stress kuzorora. Ndiwo mabatiro atinoita ± 0.05 mm pane valve body port nzvimbo, kunyangwe pa420 mm refu dzimba. Hatiedzi "kuedza" kurova kushivirira. Isu tinodzora nzira yekupisa kubva pakudururira kusvika pakupera kwekucheka.
- Cobalt-alloy kuenderana: Hongu-isu tinogara tichikandira aruminiyamu kutenderedza cobalt-nickel inoisa (AMS 5387, T800) yemasanganiswa epombi yehybrid. Kiyi yekudurura inotevedzana uye yepakati tembiricha kutonga mukati me ± 15 ° C ye eutectic point.
- GD&T kuuraya: Isu tinosimbisa chinzvimbo, chimiro, uye runout tichishandisa Zeiss CONTURA CMMs-kwete chete pakuongororwa kwekupedzisira, asi mushure mekuita hutsinye uye zvakare mushure mekunetseka-kuzorodza annealing.
- Traceability: Yese inokandwa inotakura laser-etched QR kodhi inobatanidza kune yayo melt log, x-ray report, kuomarara kuverenga, uye dimensional chitupa-hapana mapepa enzira, hapana marekodhi akarasika.
Vamwe vanopokana kukanda jecha hakugone kuenderana nekudyara kwekudyara kune yakaoma aluminium geometries. Asi kuomarara hakuzi kwechikamu chekuverenga - ndezvekushanda kwekumanikidza density. Winch centre shaft roller inoda yakaenzana kugoverwa kwehuwandu, kubereka-giredhi repamusoro pekupedzisira paOD, uye chaiyo kiyi nzira kurongeka kune kureba kwemamita 1.2. Kukandira jecha kunobata zvirinani pane mari kana ukobvu hwemadziro hunosiyana kubva pa8 mm kusvika 45 mm. Sei? Nekuti isu tinodzora mwero wekutonhodza kuburikidza nekutonhora kwenzvimbo uye nemaoko ekuvharisa-kwete chete mold zvinhu. Takaendesa 210 kg aluminium castings neCpk> 1.67 pamabhori akakosha, akasimbiswa pasi pemutoro pa400 bar hydraulic test rigs.
Chaiyo-yepasirese kuendesa inotsamira pazvinhu zviviri izvo vatengi vazhinji vanofuratira: kugadzirira zvinhu uye kuita pachena. Isu tinotenga A383 uye 319 alloys mu500 kg batches-yakafanoongororwa, isati yaomeswa, yakagadzirira kunyunguduka mukati meawa makumi maviri nemana ekusimbisa kurongeka. Uye isu tinogovera zvigadziriso zvekugadzira-chaiyo-nguva: kwete "kukanda kwatanga," asi "mold assembly yakapera na09:22, kudururwa kwakarongwa na14:00, inotarisirwa shakeout na18:40." Kuonekwa ikoko kunoita kuti zvikwata zvekutenga zvigadzirise zvinhu, zvikwata zveQA zvironge CMM slots, uye mainjiniya edhizaini anosimbisa zviyero zvechinyorwa chekutanga mabasa echipiri asati atanga.
Kana yako inotevera aruminiyamu yekukanda purojekiti ichida zvinopfuura pepa rekoteti — kana ichida simbi inonzwisisika, kukanda-machining interface kuronga, uye kutevedzera kwakanyorwa kwemafuta & gasi kana nharembozha hydraulics — iwe unoda shamwari inobata jecha kukanda senge enjiniya system, kwete danho rekutengesa. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshanda nenzira iyoyo-kwete nekuti inonzwika zvakanaka pawebhusaiti, asi nekuti mavharuvhu ekumanikidza anodonha, pombi dzimba dzinotsemuka, uye mawinji shafts anotadza kana fungidziro ichitsiva data. Isu tinovaka zvikamu zvealuminium izvo zvinopona pamazana gumi ekutanga-uye 100,000 anotevera.
