Pamene nyumba yanu ya hydraulic valve iyenera kukhala ndi ± 0.02 mm kulolerana pansi pa 350 bar pulsation-kapena cobalt alloy pump nozzle yanu imapulumuka maola 8,000 mu ntchito ya gasi wowawasa - simukungoyitanitsa zoponya. Mukuyenerera a fakitale yopangira makina opangira makina monga chowonjezera chaukadaulo cha gulu lanu la uinjiniya.
Tawonapo mapulojekiti ambiri akuyimitsidwa pachipata choyambira: kugwedezeka kwapang'onopang'ono pambuyo pa chithandizo cha kutentha, kuchepa pang'ono m'zigawo zopyapyala za AMS 5387, ma callout a GD&T amatanthauziridwa molakwika ngati "gawo lovomerezeka" m'malo movutikira. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timachita chilichonse chojambula ngati chinthu chogwira ntchito - osati chopanda kanthu chomwe chidzapangidwa pambuyo pake. Izi zikutanthauza kuwongolera zitsulo * musanathire, kutsimikizira kapangidwe ka tirigu * pambuyo * kulimba, ndi kutseka geometry * pa nthawi ya * CNC kumaliza — zonse pansi pa denga limodzi lovomerezeka ndi ISO ku Qingdao.
Chifukwa chiyani kuponyera kulolerana kumayamba kale nkhungu isanatseke
Zolephera zambiri zoponya mwatsatanetsatane zimabwerera ku mipata itatu yomwe ingapeweke: kusagwirizana kwa zinthu, kugawikana kwa ndondomeko, ndi zolakwika za handoff dimensional. Timawatseka mwadala.
Choyamba, kuwongolera kwazinthu zopangira sikukhudzana ndi satifiketi - ndizokhudza kutsata kwa batch mpaka pachipika chosungunuka. Mukatchula T800 cobalt-based alloy, timachokera kwa ogulitsa omwe ali ndi luso lomwe amapereka malipoti athunthu *ndi* mbiri yamafuta amtundu uliwonse wa ingot. Palibe chemistry "yofanana". Palibe zongoganizira za "monga-cast". Kuthira kulikonse kumatsimikiziridwa motsutsana ndi ma curve amakina a AMS 5387-osati kulimba kwamphamvu, koma kutalika kwa fracture ndi kuuma kwa gradient kudutsa makulidwe agawo.
Chachiwiri, kuphatikizika koyima kumachotsa kulekerera komwe kumapha magawo olondola kwambiri. Kuponyera mchenga kokha sikungathe kugwira ± 0.15 mm pa nyumba ya silinda ya 400 mm. Koma gulu lathu la oyambitsa likapanga ma geting ndi akatswiri opanga makina - ndipo magulu onse awiri amawunikiranso lipoti lomwelo la CMM pamtundu wa mchenga wobiriwira - timachotsa malupu okonzanso. Mzere wathu woponyera ndalama umayendetsa ndime zovuta zamkati mu ma valve opanikizika; mzere wathu wamchenga umapanga maziko akuluakulu a mpope mpaka 1,200 kg-onse amadyetsa mwachindunji mu ma cell a CNC amitundu isanu komwe mabowo omaliza, malo osindikizira, ndi nkhope zokwera amapangidwa mu setups imodzi.
Chachitatu, kuyendera si malo ochezera - ndikutsimikizira mosalekeza. Zomwe zikubwera zimapeza spark spectrometry ndi kuyesa kwa ultrasonic. Macheke amkati amagwiritsa ntchito ma Zeiss CMM okhala ndi ma probes owerengeka pamadatum ovuta, kuphatikiza zofananira ndi mawonekedwe omwe amakhudzidwa ndi mbiri ngati ma nozzle orifices. Kuyang'anira komaliza kumaphatikizapo kuyesa kuthamanga kwa magwiridwe antchito (mpaka mipiringidzo 500), kulowa kwa utoto pazolakwika zapansi panthaka, ndi kutsimikizira kuuma kwapang'onopang'ono pa ISO 4287 - zolembedwa mu dossier yokwanira yomangirizidwa ndi manambala ena.
Pomwe zoyambira zokhazikika zimayimitsidwa, kuyika kolondola kumayamba
Ena angatsutse: "Makina a CNC amapereka kulolerana kokulirapo kuposa kuponyera - ndiye bwanji kutayidwa?" Zovomerezeka—koma zosakwanira. Kukonza nyumba ya pampu ya pistoni ya 300 mm kuchokera kuzitsulo zolimba zosapanga dzimbiri kumawononga 78% yazinthu zopangira, kumapangitsa kuti pakhale kupsinjika kotsalira, ndikuwononga kuwonongeka panthawi ya kutentha. Kuponya mawonekedwe apafupi ndi ukonde kenako kumaliza malo ovuta okha kumadula nthawi yotsogolera ndi 40%, kumachepetsa kusiyana kwa kulemera pakati pa magulu, ndikuteteza kutuluka kwa njere kuti musatope.
Wosiyanitsa weniweni? Kugwira zimene ena amakana. Cobalt-nickel alloys ngati AMS 5387 sizongovuta kupanga makina - ndi osakhazikika. Kutentha kwambiri pakupera? Grain boundary oxidation imawononga kukana kwa dzimbiri. Kuzizira mothamanga kwambiri poponya? Micro-porosity imapanga mukusintha kwakuya mpaka kuonda. Timagwiritsa ntchito pulogalamu yofananira yotenthetsera gawo lililonse latsopano la geometry, kusintha kuziziritsa munthawi yeniyeni pogwiritsa ntchito ma thermocouples ophatikizidwa, ndikutsimikizira ma microstructure okhala ndi zitsulo zam'mbali-osati pazolemba zoyambirira zokha, koma kotala lililonse pamagawo opanga.
Zomwe tapempha kwambiri zimatsimikizira izi: nyumba za silinda za pampu ya piston zokhala ndi concentricity <0.03 mm kutalika kwa 600 mm; ma winch center shaft rollers okhala ndi zone zovala zolimba zomwe zimakumana ndi ASTM A957 Grade 100 tensile specs; mapulagi a cobalt osakhazikika okhala ndi ma groove osindikizira awiri omwe amafunikira ± 0.015 mm groove m'lifupi ndi Ra 0.4 μm kumaliza. Izi sizinthu zamakalata. Ndi mayankho opangidwa - komwe magawo opangira, matenthedwe amatenthedwe, ndi njira zamakina zimakonzedwa kuyambira Tsiku Loyamba.
Momwe mungawonere fakitale yowona mwachilungamo
Funsani mafunso atatu awa—ndipo onani mmene akuyankhira:
- "Ndiwonetseni malipoti anu atatu omaliza a CMM a gawo limodzi ndi GD&T callouts olimba kuposa ± 0.05 mm." Ngati akuzengereza, kapena kugawana ma templates, chokanipo. Mashopu enieni amasunga zolemba zakale za digito.
- "Kodi mumawongolera bwanji kuchepa kwa khoma la 12 mm moyandikana ndi bwana wa 45 mm?" Mayankho osamveka bwino okhudza “mapangidwe apamwamba” amangoyerekeza. Mashopu olondola amawonetsa zotulutsa zenizeni zamafuta ndikuwonetsa delta yoyezedwa pakati pa miyeso ya as-cast ndi post-HT.
- "Kodi mukukanidwa bwanji pa AMS 5387 m'miyezi 12 yapitayi-ndipo chomwe chinayambitsa zolephera zitatuzi chinali chiyani?" Kuwonekera apa kumalekanitsa abwenzi ndi ogulitsa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imasindikiza dashboard yake yapachaka mkati—ndipo imagawana ma metric oyenerera ndi othandizana nawo oyenerera mukawapempha. Chiyembekezo chathu chaposachedwa cha kutsata kwazinthu zololera kwambiri chikuyima pa 99.73%, ndipo zopatuka zokhudzana ndi kuchepera zimawerengera zosakwana 0.8% zosagwirizana - kutsika kuchokera ku 2.1% zaka ziwiri zapitazo titakweza njira yathu yowunikira kutentha kwa nkhungu.
Zigawo zazitsulo zolekerera kwambiri sizimatuluka muzojambula zabwino kwambiri. Amatuluka pachiwopsezo chogawana, njira zolembedwa, komanso chidwi chosalekeza pazomwe zimachitika pakati pa kutsanulira kosungunuka ndi kukhudza komaliza kwa CMM. A fakitale yopangira makina opangira makina sichimatanthauzidwa ndi zida zake-zimatanthauzidwa ndi momwe zimagwirizanirana mwamphamvu ndi zitsulo ndi kutsimikizika kwa geometric. Ndiwo muyezo womwe timapangira. Kuthira kulikonse. Gawo lirilonse. Nthawi iliyonse.
