Pamene nyumba yanu ya hydraulic valve iyenera kupirira ± 0.005 mm pansi pa kukakamizidwa kwa bar 350-kapena mpweya wanu wapampu wa cobalt-alloy umapulumuka maola 12,000 mu gasi wowawasa wowononga-gawolo silimangopangidwa ndi makina. Zimatsimikiziridwa, zozikika mwazitsulo, komanso zotsekedwa pang'onopang'ono zisanachoke pafakitale. Ndicho chenicheni cha ntchito ya ultra precision Machining fakitale kutumikira machitidwe ofunikira kwambiri amakampani.
Palibe kunyengerera pamachitidwe a aloyi - kuwongolera kokha
Tawona ma projekiti ambiri akuyimilira pachiwonetsero chifukwa kuyankha kwazinthu sikunakhazikitsidwe m'ndondomekoyi - osati papepala. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ma aloyi a cobalt-nickel ngati AMS 5387 ndi T800 samatengedwa ngati "makina ovuta". Iwo ndiwo maziko. Kukula kwawo kwamafuta, kuchuluka kwa kuuma kwa ntchito, komanso kukhudzidwa kwa micro-crack kumayambitsa kutsatizana kwa njira, kuzizira kozizira, komanso mbiri yothamangitsa ma spindle. Mwachitsanzo: popanga pulagi ya alloy ya T800 ya pampu yothamanga kwambiri, timachepetsa chakudya pa dzino ndi 32% motsutsana ndi Inconel 718 yanthawi zonse—ndikuwonjezera kuwunika kwa kutentha kwanthawi yeniyeni pa mawonekedwe ocheka. Chifukwa chiyani? Chifukwa madulidwe a T800 amatsika 40% pamwamba pa 400 ° C. Popanda kubwereza kwa mayankhowo, kukhulupirika kwapamtunda kumalephera kuwunika komaliza.
Izi sizongoyerekeza. Imabwerezedwanso m'magulumagulu - chifukwa chiphaso cha zinthu zopangira chimatsimikiziridwa *asanatulutse*, osati pambuyo pake. Kutentha kulikonse kumakhala ndi kutsata kokwanira: kusanthula kwasungunuka, lipoti la kukula kwambewu, ndi data yoyeserera yolumikizidwa ndi nambala ya chigawocho. Palibe zongoganizira. Palibe zoletsa.
Kuphatikizika koyima sikuli kophweka-ndi inshuwaransi yowoneka bwino
Otsatsa ena akuponya kunja, kenako subcontract CNC ntchito. Izi zimabweretsa masinthidwe atatu osiyana a ma data, mipata iwiri ya mbiri yamafuta, ndi kuyankha kwa zero pakusamuka kwazovuta zotsalira pakati pa njira. Sitichita zimenezo. Malo athu ogwirizana ndi ISO amayang'anira kuyika kwa ndalama, kuponya mchenga, makina a CNC amitundu yambiri, chithandizo cha kutentha, ndi kutsirizitsa pamwamba - zonse pansi pa denga limodzi, ndikugawana CMM ndi kutanthauzira kogwirizana kwa GD&T.
Zotsatira zake? Nyumba ya silinda ya pampu ya piston imafika poyang'aniridwa komaliza ndi palibe kukonzanso kofunikira pazifukwa zovuta kwambiri - ngakhale pambuyo pozimitsa ndi kupsa mtima. Bwanji? Chifukwa mawonekedwe oponyerawa amaphatikiza ndalama zolipirira mwadala zomwe zimagwirizana ndi kusokonekera komwe kunanenedweratu kuchokera kumayendedwe otenthetsera. Pulogalamu ya CNC imalipira chip choyamba chisanawuluke.
Kuoneratu zam'tsogolo kumeneku kumangogwira ntchito ngati mainjiniya akukhala pafupi ndi akatswiri opanga makina panthawi yowunikiranso za DFMA - komanso onse akamagwiritsa ntchito labu yofanana ya metrology. Ndilo ntchito yathu ya tsiku ndi tsiku.
Geometry yogwira ntchito imapambana kumapeto kwa zodzikongoletsera - nthawi iliyonse
Makasitomala nthawi zambiri amafunsa kuti: "Kodi mungakumane ndi Ra 0.4 µm?" Koma chomwe amafunikira kwambiri ndikuyenda kosasinthasintha kwapampando wa valve yokakamiza-kapena zero kugunda mu cholozera cha winch center shaft pansi pa cyclic torsion. Kukakamira pamwamba ndi njira, osati mapeto.
Ichi ndichifukwa chake ma protocol athu omaliza ali okhudzana ndi kugwiritsa ntchito: electropolishing ya ndime zamkati za cobalt-nozzle (kuchotsa tinthu tating'onoting'ono toyambitsa cavitation), plating yolimba ya chrome yokhala ndi ma gradients owundana pazikhazikiko zapampu zachitsulo (kuyesa kukana kuvala ndi kutopa kwa moyo), ndi kuphatikizika kwa isotropic kokha komwe kupangika kwa filimu ya hydrodynamic sikungatheke.
Timalemba magawo onse - osati ma Ra omaliza, koma kudula pH, kusefera ma micron, ndikukhala nthawi yosambira. Ngati kulephera kwamakasitomala kumabwerera kumtunda woyambika, titha kubwereza chipika chonse chomaliza - osangoyerekeza.
Kutumiza si tsiku - ndi mndandanda wazinthu zotsimikizika
"Kupereka nthawi" sikukutanthauza kanthu ngati magawo 10 oyambirira akulephera kuyesa ntchito. Timakhazikitsa zitseko zotulutsidwa: kutsimikizira kwazinthu zomwe zikubwera → kuponyera NDT (UT + RT) → cheke cholimba cha makina opangira makina → in-process CMM scan pomaliza 30% → kutsimikizira kukhazikika kwapambuyo kutentha kwa kutentha → kuyesa komaliza (kukakamiza, torque, kutuluka). Chipata chilichonse chimafunikira kusaina. Palibe kukwera. Palibe chowonjezera.
Chilangochi chimatithandiza kudzipereka ku nthawi yokhazikika - ngakhale maoda apakati - popanda kusiya kutsata. Gawo lirilonse limatumiza ndi dossier ya digito: ma cert aiwisi, zipika zochitira kutentha, malipoti a CMM, ndi zithunzi zowunikira. Osati mwachidule. Data yaiwisi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito ngati ultra precision Machining fakitale kumene zitsulo, geometry, ndi ntchito sizingasiyanitsidwe. Sitimangopanga magawo kuti tisindikize. Timakonza machitidwe awo muutumiki-ndikutsimikizira izi, gawo ndi gawo, batch by batch.
