Akatswiri akamanena za kuponyedwa kwa mchenga wa aluminiyamu kwa mavavu olimba kwambiri a hydraulic kapena mapampu, samangosankha njira - akudzipereka kuti akhazikike pansi pa njinga yamoto yotentha, kusasinthika kwapang'onopang'ono kwa ma 50 kg, ndi kulekerera zero pakuchepa kwamphamvu kwamagetsi onyamula katundu. Chifukwa chake a Aluminiyamu mchenga kuponyera foundry fakitale ayenera kuchita zambiri kuposa kutsanulira zitsulo mu nkhungu. Iyenera kugwirizanitsa sayansi yazitsulo ndi zofuna zenizeni zenizeni-makamaka pamene mbali zikugwira ntchito pa 350 bar, 180 ° C, kapena pansi pa slurry flow of abrasive.
Tawona ma projekiti ambiri akuyimitsidwa pachiwonetsero - osati chifukwa cha mapangidwe olakwika, koma chifukwa choyambira chinalibe chiphaso cha aloyi, sakanatha kukhala ndi ± 0.15 mm pa silinda ya 420-mm, kapena kuphonya ma callout a GD&T pazinthu zofunika kwambiri. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., aluminiyamu iliyonse kuponyera mchenga kumayamba ndi kutsimikizira kwa AMS 4220 kapena A380.1-osati ziphaso za mphero, koma kubwereza kwa spectrometric m'nyumba musanasungunuke. Izi sizingakambirane ngati nyumba yanu ya pampu ya pistoni ikhazikitsa $2.4M yobowola kunyanja.
Kodi chimalekanitsa chiyani fakitale ya aluminiyamu yopangira mchenga kuchokera kwa ogulitsa zinthu? Choyamba: kulamulira unyolo wonse. Sitimapereka mwayi wopanga ma core, kugwedeza, kapena kuchepetsa nkhawa. Malo athu ogwirizana ndi ISO amasamalira sitolo yachitsanzo, kusonkhanitsa nkhungu, kuthira, kutentha kutentha (T6 kapena T7 monga momwe tafotokozera), ndi CNC kumaliza-machining-zonse pansi pa denga limodzi. N’chifukwa chiyani zimenezi zili zofunika? Chifukwa kusalinganika kwa 0.08 mm pakati pa halves ya nkhungu kumakhala kusintha kwa makulidwe a 0.3 mm mu thupi la valve 120-mm-diameter. Ndipo kusiyana kumeneku kumayambitsa kutopa kwanthawi yayitali kusweka kwa fillet radius. Timachipeza pakujambula koyamba kwa CMM-osati kulephera kwamunda.
- Dimensional kukhulupirika: Timatsimikizira geometry yamkati pogwiritsa ntchito kuwala kwa 3D musanayambe kupanga nkhungu, osati kungoyerekeza kwa CAD ndi gawo, koma mchenga weniweni wa nkhungu.
- Microstructure chilungamo: Gulu lililonse limayesa kusanthula kwazitsulo za eutectic silicon morphology; coarse, singano ngati Si imawononga machinability ndi kukana kuvala
- Kukonzekera pamwamba: As-cast Ra ≤ 12.5 μm pa malo ovuta osindikizira-palibe kuphulika kwachiwiri pokhapokha ngati pakufunika kupaka utoto
- Kutsimikizira kogwira ntchito: Kuponyera valavu iliyonse kumadutsa kuyesa kwa helium kutayikira pa 1.5 × kugwira ntchito kusanayambe makina asanayambe
Ena amatsutsa kuponya mchenga sikungafanane ndi kuyika ndalama kuti mumve zambiri. Zowona-pazinthu zosachepera 1.2 mm, ndalama zimapambana. Koma kwa ma geometri ovuta monga ma winch center shaft rollers okhala ndi mano ophatikizika amagiya, zipsepse zoziziritsa, ndi ndime zamafuta? Kuponyedwa kwa mchenga kumapereka mphamvu yowongoka bwino yotentha panthawi yolimba, kuchepetsa kung'ambika kwa nthiti zopyapyala. Timagwiritsa ntchito mchenga wa silika wopangidwa ndi utomoni wokhala ndi mphamvu zowongolera (120-140) ndi kuumitsa kwa bokosi lozizira kuti tibwerezenso 200+ pa sabata. Palibe khwekhwe "pamodzi-kuchoka". Palibe kusiyanasiyana kwapamanja. Kuphatikizika kwa pneumatic ndi kuwunika kwenikweni kwa chinyezi munthawi yeniyeni.
Kusankha kwazinthu sizongoyerekeza apa. Pamene OEM yaku Europe idafunikira nyumba zosinthira zapampu ya cobalt-aloyi yomwe ikuyenda ndi crude, sitinasinthe kukhala A380. Tidayesa kuyerekezera kwamafuta pa A380 ndi AlSi10Mg - ndiye tidatsimikizira kukana kwamphamvu kwa AlSi10Mg pamwamba pa 150 ° C kunachepetsa kupotoza kwa 40% pa maola 10,000 ogwirira ntchito. Ndiko kusiyana pakati pa kutchula gawo ndi kuthetsa vuto la dongosolo. Mainjiniya athu amawunikanso malipoti a FEA ndi makasitomala-osati kuti avomereze zojambula, koma kuti awonetse zoopsa zomwe zitha kutsekereza haidrojeni pamadoko amphamvu kwambiri.
Kudalirika kwa kuperekedwa kumatengera kulosera - osati malonjezo. Timatsata madongosolo opangira mchenga wa aluminiyamu ndi kalasi ya alloy, osati tsiku loyenera. A380 imayenda Lolemba-Lachitatu; AlSi10Mg imapeza malo a Lachinayi-Lachisanu kuti apewe kuipitsidwa. Gawo lililonse loponyera limakhala ndi kutsata kwathunthu: ID ya ng'anjo, chipika cha kutentha kwasungunuka, sitampu ya nthawi yothira, ndi siginecha ya opareshoni. Ngati kasitomala apempha PPAP Level 3, timapereka ma cert, malipoti a CMM ankhani yoyamba, data yoyeserera, ndi zithunzi za radiographic - osati mwachidule. Umu ndi momwe timasungira 98.7% potumiza nthawi yake pamagalimoto apakati (50-500 pcs/mwezi) kudutsa North America, Germany, ndi Singapore.
An Aluminiyamu mchenga kuponyera foundry fakitale amapeza chidaliro osati kudzera m'mabuku, koma kudzera mu zomwe zimachitika kuponyako kukazizira: palibe tsamba lankhondo losayembekezeka, palibe kukonzanso kwa mphindi yomaliza pamadatum, palibe kukana modabwitsa pakuwunika komaliza. Ku QINGDAO QIANGSENYUAN TECHNOLOGY, kusasinthasintha kumeneku kumabwera chifukwa chokonza nkhungu iliyonse ngati chida cholondola, osati zongotayidwa. Kuyambira pomwe aluminiyamu yosungunuka igunda nkhungu mpaka kuyesa komaliza, timayesa momwe gawolo lingakumane nalo - osati kujambula kokha.
Kuyang'ana m'tsogolo, kuyang'ana kwathu kumanola: kuphatikizika kolimba kwa mchenga ndi zida zosakanizidwa zowonjezera zida zotsika kwambiri, zovuta kwambiri; kukulitsa kuyanjana kwa AMS 5387 pamisonkhano yosakanizidwa ya aluminiyamu-cobalt; ndi AS9100 certification ndi Q4 2025. Chifukwa m'badwo wotsatira wa zigawo zazitsulo zolondola sizidzafotokozedwa ndi kuponyera kokha-koma momwe kuponyera mopanda malire kumathandizira kugwira ntchito komwe kuli kofunikira kwambiri.
