Pamene mainjiniya afotokoza aloyi zitsulo ndalama kuponyera fakitale ntchito, sikuti amangoyitanitsa magawo-akuteteza kukhazikika kwamphamvu pansi pa 400 MPa hydraulic loads, microstructural consistency kudutsa 500-unit batches, ndi zero kulolerana kwa porosity pamipando ya ma valve. Ndicho chenicheni chogwirira ntchito kumbuyo kwa zigawo zamafakitale zolondola monga nyumba za silinda ya piston kapena AMS 5387 cobalt alloy nozzles - mbali zomwe kupatuka kwa 0.02 mm kumayambitsa kulephera kugwira ntchito.
Taziwonera tokha: zida zamafuta aku North America OEM idachedwetsa kutumizidwa kwa milungu 11 chifukwa chopereka "chotsimikizika" cha aloyi aloyi adalephera kuyezetsa akupanga pa maola 72 atatha kutentha. Chifukwa chake? Kusakhazikika kwazinthu zopangira komanso chemistry yosatsimikizika - osati kukonza zolakwika. Chochitika chimenecho chinasinthanso momwe timafikira kuyika ndalama za aloyi ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Ichi ndichifukwa chake chogudubuza chilichonse cha T800 chochokera ku winch center shaft chimayamba ndi ma ingots otsimikiziridwa ndi mphero, osati katundu "wogwirizana" wamba.
Kulondola kwenikweni pakuponyera zitsulo za alloy kumafuna kuphatikiza koyima - osati kungoponya, koma kuwongolera zitsulo, kumaliza kwa ma axis angapo, ndi kuyang'anira GD&T - zonse pansi padenga limodzi logwirizana ndi ISO. Kuponyera mchenga kumagwira ntchito zambiri za geometry; kuyika ndalama kumapereka kutha kwa 0.05 mm Rz komwe kumafunikira nkhope zosindikizira. Koma kusiyanitsa kwenikweni kuli pa zomwe zimachitika pakati pa masitepewo: njira zochiritsira kutentha kwanthawi yake mpaka ± 1 ° C, kutsimikizika kwa CMM kwa zinthu zofunika kwambiri za datum * zisanachitike * ndi * pambuyo * mpumulo wa kupsinjika, komanso kuyeza mowoneka bwino kwa zotsalira zamkati zomwe zimatha kutopa kwa mbewu kumang'ambika pamapampu apamwamba. Sitimapereka ntchito kunja kwa matenthedwe. Sitikudumpha macheke asanayambe makina. Timatsimikizira maere aliwonse motsutsana ndi ASTM A957 ndi EN 13381-chifukwa "monga-cast" sizodziwika; ndi chotengera chowopsa.
- Chilango chakuthupi: Palibe zolowa m'malo popanda kusaina mainjiniya-ngakhale zinthu zazing'ono zophatikiza. Wofuna chithandizo atapempha 316L m'malo mwa F22 kuti akhazikitse pampu yamadzi a m'nyanja, tidayambitsa kaye kaye za dzimbiri. Zotsatira: 316L inachita dzimbiri 3.2 × mofulumira pa 85°C. Tidagwirizira mzere pa F22-ndikuwonjezera zotchingira zosapanga dzimbiri zowirikiza pomwe liwiro lothamanga limapitilira 4 m/s.
- Njira kukhulupirika: Zipolopolo zotulutsa ndalama zimathiridwa phula pa 120 ° C, osati "kutentha kwachipinda + chinyezi chozungulira." Mawonekedwe a sera amakhazikika kwa maola 72 asanakutidwe ndi matope a ceramic. Chifukwa chiyani? Chifukwa chinyontho chotsalira chimayambitsa matuza ang'onoang'ono omwe amatsekeredwa ndi oxide inclusions pakutsanulira.
- Kutsimikizira kogwira ntchito: Nyumba iliyonse ya valve yokakamiza imakhala ndi umboni wa hydrostatic pa 1.5 × kugwira ntchito, ndiye kuyesa kwa helium pa 1 × 10⁻⁹ mbar·L/s sensitivity-osati kungoyang'ana dimensional. Ngati sichigwira, sichimatumiza.
Ena amatsutsa kuti mafakitale opanga zinthu zakunyanja amapereka mitengo yabwinoko. Amatero-mpaka mutakhala ndi mtengo wokonzanso kuchokera ku mbewu zosafanana, kapena ndalama zokwana $18,000 zonyamulira ndege kuti mulowe m'malo mwachangu mukalephera kumunda. Makasitomala athu ku Germany ndi ku Texas akuti ndi 42% kutsika mtengo wonse wokhala umwini pazaka zitatu za moyo wautumiki-osati chifukwa mawu athu ndi otsika, koma chifukwa zokolola zathu zoyamba zimaposa 94.7%, ndipo kubwereza kwathu kumagwira ± 0.015 mm kudutsa mayunitsi 200. Kusasinthika kumeneku kumabwera chifukwa chowongolera unyolo wonse: kusanthula kwazinthu zotsimikizika, kusanthula kwamkati mwanyumba, nkhungu za ceramic zopangidwa ndi CNC, ndi kuyerekezera komaliza ndi laser koyerekeza ndi CAD yodziwika.
Ngati ntchito yanu ikufuna mphamvu za fakitale ya alloy zitsulo zopangira ndalama zomwe zimatengera AMS 5387 ngati maziko-osati kuchotserapo-muyenera abwenzi omwe adapanga T800 pa 32 HRC popanda kupyola, omwe amatsimikizira kusiyana pakati pa ma interdendritic m'mapangidwe ang'onoang'ono, ndi omwe amachitira ma callouts a GD&T monga mapangano, osati malingaliro. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga luso limeneli mu sitepe iliyonse - osati monga chinenero cha malonda, koma monga ndondomeko zoyendera zolembedwa, zolemba zakale zosungidwa, ndi zolemba zenizeni zenizeni zomwe zimayikidwa mu mapasa a digito a gawo lililonse. Kulondola sikukwaniritsidwa pakuwunika komaliza. Zimatsekedwa pa siteji ya sera, zotsimikiziridwa pa kusanthula kwasungunuka, ndipo zimatsimikiziridwa pamene gawolo lipulumuka kuyesedwa kwake koyamba kwa maola 500.
