Mitengo yamitengo yotayika ya sera imasiyana mosiyanasiyana - ndi aloyi, zovuta, voliyumu, komanso kulolerana. Koma ogula ambiri samazindikira kuti dalaivala wokwera mtengo kwambiri sizinthu kapena ntchito. Ndi kukonzanso komwe kumachitika chifukwa cha zoyembekeza molakwika pagawo la mawu. Taziwonapo kangapo: kasitomala amatumiza fayilo ya CAD, amalandira mawu "opikisana", amavomereza-ndiyeno amazindikira zapakati pakupanga kuti kutsirizitsa kwapamwamba sikungagwirizane ndi mawonekedwe awo osindikizira, kapena kuti gawo la AMS 5387 cobalt alloy likufunika chithandizo cha kutentha musanapange makina - koma mawu oyambirirawo amaganiziridwa kuti atumizidwa. Kusagwirizana kumeneku kumawonjezera 22-37% pamtengo wosakonzekera ndikukankhira nthawi yotsogolera ndi masabata 3-6.
Chifukwa Chake "Fakitale Yotaya Mitengo Yotayika" imalephera Kupereka Mtengo Weniweni
Zosaka zambiri pa intaneti fakitale yotaya phula yamtengo wapatali bweretsani matebulo ageneric: “Chitsulo chosapanga dzimbiri: $8–$15/kg”, “Inconel: $22–$40/kg”. Manambala amenewo alibe tanthauzo popanda nkhani. Thupi la valavu ya 1.2-kg T800 cobalt cobalt ndi ± 0.05 mm GD & T callouts, njira zoziziritsira mkati, ndi Ra 1.6 pamwamba pa mapeto osindikizira amtengo wapatali amawononga ndalama zoposa 5-kg 316 zosapanga dzimbiri zosapanga dzimbiri zokhala ndi ± 0.5 mm kulolerana ndipo palibe zofunikira zogwirira ntchito-ngakhale zolemera kanayi. Mitengo yeniyeni yamtengo wapatali ndi kukhazikika kwa geometry, kusasinthasintha kwazitsulo, ndi kusakanikirana kwa ndondomeko-osati kulemera kokha.
Timatchula pulojekiti iliyonse yotayika yotayika payekha chifukwa timapanga makina omwe timaponyera. Palibe kutumiza kunja. Palibe ma handoffs pakati pa foundry ndi shop floor. Makasitomala akatitumizira chojambula cha injini ya winch center shaft roller-yopangidwa kuchokera ku AMS 5387, yomwe imafunika kutsimikiziridwa kwathunthu kwa microstructure, komanso yogwirizana ndi ISO 1940 G2.5 - timadziwa ndendende kuchuluka kwa ng'anjo zamoto, malo oyendera a CMM angati, ndi mapepala angati omaliza omwe amatenga. Kuwongolera koyima kumeneko kumathetsa kulosera. Mawu athu akuphatikiza masitepe ovomerezeka, ma cert azinthu pa ASTM E112 ndi E354, ndi zolemba za kutentha kwa kutentha - osati chiwerengero cha kilogalamu imodzi.
Zinthu Zinayi Zomwe Zimasuntha Mtengo Wotaya Sera
- Makhalidwe a alloy mu zisankho zogulitsa: Cobalt-nickel alloys ngati T800 amachepetsa 12-15% pansi pa 304 zosapanga dzimbiri panthawi yolimba-koma amakhalanso 3.2 × owoneka bwino kwambiri akasungunuka. Izi zimafuna kuwongolera kolimba kwa zipolopolo komanso kutsitsa pang'onopang'ono. Timasintha zololeza zathu za sera ndikuumba mbiri ya preheat molingana. Mafakitole amtundu uliwonse amatsatira lamulo limodzi lochepetsera ma aloyi onse - ndikulipiritsa ndalama zina pambuyo pake kuti ziwongoleredwe.
- Kachulukidwe ka mawonekedwe motsutsana ndi njira yolowera: Maziko a mpope okhala ndi mabowo 17 obowola, obowoledwa, obowoleredwa, ndi ophatikizika sagulidwa ndi kuwerengera mabowo-amakhala ndi mtengo ngati mabowowo adutsa njira yolowera. Timayesa njira zoyendetsera poyamba. Ngati doko loziziritsa bwino lagona mwachindunji munjira yachitsulo, timapanganso chipata - osati gawolo - ndikutengera nthawi yaukadauloyo. Mafakitole ambiri amaona kuti gating ndi chinthu chokhazikika.
- Zofunikira pa umphumphu: Ra 3.2 ndi muyezo. Ra 0,8 pa mpando kuthamanga valavu amafuna pambuyo kuponyedwa galasi mkanda kuphulika, ndiye CNC contouring, ndiye electrochemical kupukuta. Gawo lirilonse limasintha mawu. Timalemba zolemba momveka bwino - ndikuwonetsa komwe kumaliza kulikonse kumagwira - ndiye kuti palibe kusamveka bwino pa First Article Inspection.
- Kuzama kwa traceability: Kwa mafuta ndi gasi kapena ma hydraulic, kutsata kwathunthu kwa batch sikofunikira - ndikoyenera. Timalemba ma melt lot, ID ya ng'anjo, chipolopolo, zotsatira za XRF scan, ndi mipiringidzo yoyeserera pa kutentha. Izi zimawonjezera 4.7% pamtengo woyambira - koma zimalepheretsa $ 250k kulephera kwamunda. Makasitomala amene kudumpha sitepe iyi amalipira kwambiri kutsika.
Kodi Mawu a Fakitale ya Wax Yotayika Yowonekera Amaphatikizapo
Mawu enieni si PDF yokhala ndi mizere itatu. Ndi kugwirana chanza kwaukadaulo. Zathu nthawi zonse zimakhala ndi:
- Chitsimikizo cha zinthu - kuphatikiza zofunikira za lipoti la mayeso a mphero (mwachitsanzo, ASTM A494 Grade CD4MCuN yokhala ndi kuyesa kwa Charpy pa -46 ° C)
- Mapu olekerera ngati-cast: ndi miyeso iti yomwe imakhala ndi ± 0.1 mm (monga ma ID a bore), omwe amakhala ndi ± 0.3 mm (monga ma OD okwera), ndipo chifukwa chiyani
- Tanthauzo la Machining scope: ndi zinthu ziti zomwe zakonzeka, zomwe zimafuna kuchotsedwa kwa katundu wa CNC, komanso zomwe zimafunikira kupukuta kapena kupukuta
- Protocol yoyendera: Mayina a pulogalamu ya CMM, kukula kwa mawonekedwe ofananitsa omwe amagwiritsidwa ntchito, ndi njira zovomerezera za porosity pa ASTM E155
- Kudzipereka kopereka: osati "masabata 4-6", koma "masiku 18 a kalendala pambuyo pa kuvomera kwa sera ndi risiti ya deposit" - ndi njira zomveka bwino ngati nthawi yotsogolera ikusintha.
Mwatsatanetsatane uwu umachotsa 92% ya ma loops owunikira mainjiniya. Pampu imodzi yaku North America OEM idachepetsa kuzungulira kwake kwa NPI kuchoka pa masabata 14 mpaka masabata 8.5 titasinthira kumayendedwe athu.
Kupeza Mtengo Wanu Wotayika Wa Wax Molondola-Koyamba
Yambani ndi kujambula kwanu-koma musayime pamenepo. Gawani zolinga zanu zogwirira ntchito. Ndi 0.002 ″ kutha pa nyumba ya silinda ya pampu ya piston kuti ikhale yolimba? Kapena posungira zisindikizo? Kodi mphuno ya cobalt alloy imafuna kukana kutopa kwamafuta - kapena kungokana kukokoloka? Context imasintha chilichonse. Timafunsa mafunso awa patsogolo-osati nkhungu itathiridwa.
Pitani https://www.tsingtaocnc.com kupempha mtengo wamtengo wotayira wa sera wotayika kufakitale. Kwezani fayilo yanu ya CAD, tchulani momwe mungagwiritsire ntchito, ndikuwonetsa zofunikira: mtengo, liwiro, kapena kulondola. Tiyankha pasanathe maola 48 antchito ndikudulira mzere-osati kusiyanasiyana. Chifukwa pamene gawo lanu likugwira ntchito pa 4,500 psi mumtundu wa valve subsea, "pafupifupi" si nambala. Ndi ngozi.
