Kuponyera Foundry sikungotsanulira zitsulo zosungunuka mu nkhungu. Ndipamene sayansi yakuthupi imakumana ndi chikhalidwe chambiri-ndipo pomwe munthu amalakwitsa kupanga mapangidwe, kusankha aloyi, kapena kuzizira kumatha kutenga milungu ingapo pakukonzanso, osati madola okha. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., taponyera 12,000 ma valve okakamiza ndi masilinda a pampu ya piston kuyambira 2018-iliyonse ikugwira zolimba zolimba pansi pa 0.05 mm ndikupulumuka 300+ bar hydraulic cycle. Chochitika chimenecho chinatiphunzitsa kanthu kena kofunikira: kuyika maziko ake molondola kumayamba kalekale ng'anjoyo isanayatse.
Mapangidwe a Castability—Osati Zongogwira Ntchito
Mainjiniya nthawi zambiri amakonza zida zophatikizira kapena kugawa zopsinjika - kenaka amagawira zojambula poyembekezera kuti ochita masewerawa "apangitse kuti zitheke." Koma mchenga ndi kuponya ndalama zimakhala ndi malire olimba. Nthawi ina tidalandira fayilo ya CAD ya nyumba yapampu ya cobalt-alloy yokhala ndi zigawo za khoma la 2.3-mm ndi nthiti zamkati zotalikirana ndi 4.7 mm. Chigawocho chinang’ambika panthaŵi ya kugwedezeka—osati chifukwa cha kuthirira kosakwanira, koma chifukwa chakuti matenthedwe amatenthedwa anaposa zenera lolimba la AMS 5387. Tinakonzanso nthiti za geometry, kuwonjezera zoziziritsa kukhosi, ndi kusamutsa mzere wolekanitsa ndi madigiri 8. Zokolola zidalumpha kuchoka pa 62% kufika pa 98%.
Macheke ofunikira omwe timayendetsa tisanatchule:
- Kuchuluka kwa gawo locheperako: ≥4.5 mm kwa castings zitsulo, ≥3.2 mm kwa cobalt-nickel aloyi ngati T800
- Radius-to-wall ratio: Ngodya zamkati ziyenera kukhala ≥0.6 × moyandikana ndi khoma kuti mupewe misozi yotentha
- Undercut tolerance: Nsapato za mchenga zimalekerera ≤15 ° kukonzekera; njira zoyendetsera ndalama zimafunikira ≥0.5 ° mbali iliyonse-kapena makina opangidwa ndi CNC
- Kudzipatula: Pewani mabwana oonda, odzipatula kapena ma flanges - amazizira msanga, amachoka kuzinthu zambiri, ndikutsegula tinjira tating'onoting'ono.
Ngati GD&T yanu ikufuna kuti ikhale yowona pagawo lomwe laponyedwa mu nkhungu, tsimikizirani ngati malowo adzasinthidwa pambuyo pake. Timasindikiza 87% yazitsulo zathu zachitsulo ndi zitsulo mpaka pomaliza - chifukwa malo oponyedwa nthawi zambiri sagwira ± 0.1 mm kulondola kwa 300 mm.
Kusankha kwa Aloyi Kumasintha Chilichonse-makamaka Pamene Simungathe Kuchipanga Pambuyo pake
Cobalt-nickel alloys ngati AMS 5387 kapena T800 sanasankhidwe kuti azikongoletsa. Amatchulidwa pamene kukana kukokoloka kwa nthaka, mphamvu ya kukwawa pamwamba pa 650 ° C, kapena ntchito yosagwira maginito - monga mafuta ndi gasi otsika pansi kapena zodzigudubuza za winch center shaft. Koma zinthu zomwezo zimawapangitsa kukhala ovuta kwambiri ku makina pambuyo poponya. Pulagi imodzi ya T800 imatenga maola 11.2 a mphero yamitundu yambiri pogwiritsa ntchito zida za PCD ndi zoziziritsa kukhosi. Chifukwa chake ngati gawo la geometry liloleza, timaphatikiza makinawo munjira yokhayokha-kuwonjezera mabowo a dowel, ma datum pads, kapena ma preforms ang'onoang'ono mwachindunji muzogulitsa.
Timapereka ma ingots onse a superalloy okhala ndi malipoti athunthu a mill test (MTRs) omwe amatha kutsatiridwa ndi kuchuluka kwa kutentha komanso kusanthula kwamankhwala. Palibe gulu lomwe limalowa m'ng'anjo popanda kutsimikizika kwa spectrographic. Chifukwa chiyani? Chifukwa kupatuka kwa 0.03% muzinthu za kaboni mu T800 kumasintha kuuma kwake kuchokera ku 32 HRC kupita ku 41 HRC - zokwanira kuphwanya choyikapo cha carbide chapakati.
Ubwino Siuwunikiridwa Mkati-Umamangidwa, Wosanjikiza ndi Gulu
Opeza ambiri amayang'ana zowonetsera pazigawo zitatu: zinthu zomwe zikubwera, zowoneka bwino pambuyo pa kugwedezeka, ndi cheke chomaliza. Timawonjezera zina zinayi:
- Mold integrity scan: X-ray tomography pa 100% ya zipolopolo zipolopolo za ndalama musanayambe kusungunuka
- Thirani chipika cha kutentha: Deta ya nthawi yeniyeni ya thermocouple yolumikizidwa ku nambala iliyonse ya kutentha
- Sectional kuuma mapu: Kuwerenga kwa Rockwell C kwa 12-point kudutsa magawo agawo lililonse
- Ntchito hydrotest: Matupi onse okakamiza a valve amakumana ndi 1.5 × ovotera kuthamanga kwa masekondi a 120-ndikuzindikira kutayikira kwa 0.003 cc/min
Timasunga kutsata kwathunthu—osati kungowunika kokha, koma chifukwa kasitomala akanena za kutopa kwa maola 14,200 ogwirira ntchito, titha kukoka chipika choyambirira, poto woziziritsa, ndi mapu akuuma pambuyo pochiritsa kutentha mkati mwa masekondi 90. Liwiro limenelo limalekanitsa kukonza zoyambitsa ndi zongoyerekeza.
Chifukwa chiyani Hybrid Casting + Machining Imamenya Payekha
Mashopu ena amawona kuponya ndi CNC ngati njira zotsatizana. Timawatenga ngati maphunziro olumikizana. Nyumba zathu zamasilinda zimayamba ngati chitsulo choponyera mchenga-koma chobowolacho sichimalizidwa ndi kutembenuka. Imaponyedwa ndi chiwongola dzanja chokulirapo cha 0.8 mm, kenaka amalemekezedwa * m'malo omwewo * omwe amagwiritsidwa ntchito pomaliza CNC mphero ya nkhope zokwera ndi ulusi wamadoko. Izi zimachotsa kusintha kwa ma datums - ndikusunga kukhazikika pakati pa bore ID ndi flange OD mpaka 0.015 mm kutalika kwa 280 mm.
Kuyenda kosakanizidwa kumeneku kumatilola kuti tipereke magawo ngati makina opangira ma winch shaft roller okhala ndi zolemba pansi * ndi * as-cast gear mano - onse amakumana ndi ISO 2768-mK general tolerances, komabe akugawana mbiri imodzi yotentha komanso kapangidwe ka mbewu. Palibe chithandizo chachiwiri cha kutentha. Palibe chiopsezo chosokoneza. Kutulutsa kumodzi kokha, mbiri yabwino, tsiku limodzi loperekera.
Kupanga koyambira kumachitika bwino pamene zitsulo, geometry, ndi zolinga zopanga zimagwirizana - osati zikakambitsirana mosiyana. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sitimangoponya zitsulo. Timayika chidaliro-mu kukhazikika kwa mawonekedwe, kukhulupirika kwamapangidwe, ndi magwiridwe antchito obwerezedwa pansi pamavuto. Kaya mukutchula maziko a pampu yachitsulo chosapanga dzimbiri kapena mukuyenereza mphuno ya aloyi ya cobalt kuti igwire ntchito mopitirira muyeso, kulondola kuponya maziko mnzanu samadikirira kujambula kwanu. Amathandiza kulemba.
