Zomangamanga zamakono zimayang'anizana ndi chisankho chovuta: kutulutsa sikelo popanda kudzipereka - kapena kutsalira m'mafakitale momwe mapampu amayenera kusindikizidwa pa bar 400, ma valve amakana kukokoloka kwa cobalt-alloy kwa maola ogwirira ntchito 12,000, ndipo ma shafts amanyamulira amanyamula katundu wokhazikika pansi pakuthira mchere. Yankho si ntchito yambiri yamanja. Ndi a makina opangira mchenga fakitale-osati ngati kukweza kwa bawuti, koma ngati kamangidwe kake kamangidwe.
Takhazikitsa ndi kuyitanitsa mizere isanu ndi umodzi yotere kuyambira 2021 - zitatu m'mafakitale a hydraulic component, ma OEM awiri opangira mafuta, ndipo imodzi yophatikizidwa mwachindunji mu kampasi ya opangira magalimoto a Tier-1. Zomwe tidaphunzira sizinali zongopeka. Zinali zomveka: momwe kuwombera kwakukulu kumasinthira pamene chinyezi chozungulira chikukwera pamwamba pa 65%, chifukwa chiyani nkhungu yotumizira phula iyenera kuchepetsedwa ndi 3.2 mm pamene ikusintha kuchoka ku chitsulo chotuwira kupita ku AMS 5387 cobalt alloy molds, ndipo chifukwa chiyani "ma automated" amalephera ngati chosungira chosungira sichikusowa RFID-trigger . Zodzichitira zenizeni zimayambira pomwe chiweruzo cha munthu chimathera-ndipo pomwe kubwereza kumayambira.
Zigawo Zitatu Zosakambirana za True Automation
Mavenda ambiri amagulitsa “automated sand casting” ngati zida zamaloboti zothira mchenga wobiriwira. Ndiko kusuntha kwapamwamba-osati kuwongolera ndondomeko. A magwiridwe antchito makina opangira mchenga fakitale imakhazikika pamagulu atatu olumikizidwa:
- Kudziyimira pawokha popanga nkhungu: Osati kungothamanga kwa robotiki, koma kupanga mapu a kachulukidwe enieni pogwiritsa ntchito masensa ophatikizika a piezoresistive mubokosi lililonse la nkhungu, ndi kusintha kotsekeka kwa mphamvu yophatikizika pagawo lililonse —kofunikira kwambiri poponya nyumba zokhala ndi mipanda yopyapyala yokhala ndi makulidwe a 2.1 mm ndi ± 0.15 mm GD&T callouts.
- Nzeru zakuthupi: Kubwezeretsanso mchenga sikubwezanso batch-ndikusanthula mosalekeza. Timayang'anira kutayika kwa bentonite, kusiyanasiyana kwa chinyezi, ndi friability masekondi 90 aliwonse pogwiritsa ntchito mawonekedwe apafupi ndi infrared. Zinthu za silika zikatsika pansi pa 92.7%, makinawo amayambitsa dosing-osati pa timer, koma pakufunika kwenikweni.
- Thermal orchestration: Nthawi ya Shakeout sinakonzedwe. Izo zimasintha. Gridi yathu yolumikizidwa ndi ng'anjo ya thermocouple imawerengera kutentha kwa khungu kudutsa mfundo 48 pa nkhungu iliyonse. Ngati kuzizira kugwera kunja kwa zenera la 1.8-2.3 ° C/mphindi lachitsulo cha ASTM A48 Class 35, mzerewo umayimitsa kugwedezeka ndikubwezeretsa nkhungu kumalo owongolera mpweya - kuteteza ma microcracks omwe pambuyo pake angalephere kuwunika kwa X-ray.
Izi sizongopeka. Ndicho chimene chinathandiza wopanga mpope wina wa ku Ulaya kuti adule zinyalala zokhudzana ndi kuponyera kuchokera ku 8.4% mpaka 1.9% mkati mwa miyezi inayi-pamene akuwonjezeka tsiku ndi tsiku kuchokera ku 62 mpaka 97 nyumba zovuta.
Chifukwa chiyani Hybrid Casting-Machining Beats "Casting-Only" Automation
Ena amatsutsa: kuponya koyamba, makina pambuyo pake. Koma muzochita, izo zimapanga misalignment. Kubowola mumchenga sikungokhudza kulekerera-komanso mpumulo wotsalira wa nkhawa, kupitilira kwa mbewu, ndi mbiri ya kutentha. Pamene kuponyera ndi makina amagwira ntchito ngati ma silo osiyana, mumapeza magawo omwe amadutsa macheke a CMM koma amalephera kuyesa kwa hydrostatic pa 1.5 × kugwira ntchito.
Tidayika malo okonzeka a CNC * mu* kapangidwe ka nkhungu - osawonjezera kuponya pambuyo. Njira zathu zopangira zida zimatengera kupotoza komwe kunanenedweratu ndi kulimbitsa kayeseleledwe (pogwiritsa ntchito MAGMAsoft v7.1 kuphatikizika kwamafuta). Kenako, malo athu opangira makina a ma axis asanu amadula pang'onopang'ono * asanalandire chithandizo cha kutentha komaliza - kuchepetsa chiopsezo cha warpage ndi 63% motsutsana ndi chikhalidwe. Kuyenda kwa hybrid iyi ndichifukwa chake nyumba zathu za silinda za piston zimakwaniritsa Rz ≤ 3.2 μm pankhope zomata mwamphamvu —popanda kugaya kachiwiri.
Zomwe Mukulipira (ndi Zomwe Simukulipira)
Kuponya mchenga paokha kumawononga ndalama zambiri, koma ndalama zenizeni zimabisala kwina. Izi ndi zofunika:
- Palibe msonkho wobisika wobwezera: Mizere yodziwika nthawi zambiri imafuna kulimbikitsidwa kwachimangidwe, kagawo katsopano ka HVAC, kapena kukweza kocheperako magetsi. Maselo athu okhazikika amaphatikizana ndi denga la 6.5 m - palibe matabwa a crane, palibe maziko.
- Palibe phantom downtime: Ogulitsa amalonjeza "95% uptime." Zoonadi? Sensor calibration drift imayambitsa ma alarm abodza. Timagwiritsa ntchito kudzifufuza tokha: loboti iliyonse imatsimikizira kubwereza kwa malo ake motsutsana ndi masters a granite omwe amatsata laser maola aliwonse a 8-palibe kulowererapo komwe kumafunikira.
- Palibe ngongole yotsimikizira: ISO 9001: 2015 kutsatira si satifiketi pakhoma. Ndi ma ID amchenga opezeka olumikizidwa ndi malipoti oyeserera, mitengo ya kutentha kwa nkhungu yolumikizidwa ku madongosolo a ntchito ya ERP, ndi ma rekodi amapasa a digito pamasewera aliwonse - omwe amapezeka kuti awonedwe mkati mwa masekondi 17.
Kulangidwa kumeneku kumatipangitsa kuti titsimikizire zoperekera mawindo othamanga apakati-ngakhale ndi ma aloyi osakhazikika ngati T800 cobalt-based material, komwe kusungunuka kumakhudza mwachindunji moyo wotopa m'ma roller akunyanja a winch center shaft.
Kumene Kulondola Kumakwaniritsa Cholinga
An makina opangira mchenga fakitale sichikhudza kusintha anthu. Ndi za ukatswiri wotsogola: kuchokera pamageji owunikira mpaka kutanthauzira mawotchi otentha, kuchokera pamalumikizidwe apamanja mpaka kutsimikizira milu ya GD&T motsutsana ndi mafanizidwe amitundu yambiri, kuyambira kusanja kwakanthawi mpaka kutengera zokolola zazitsulo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga machitidwewa osati ngati ogulitsa zida-koma ngati bwenzi lopanga nthawi yayitali. Timagwirizanitsa njira zowonetsera panthawi yanu ya DFMEA. Timatsimikizira mawonekedwe a nozzle a AMS 5387 motsutsana ndi mamapu akukokoloka, osati zojambula zokha. Timapeza zopangira zovomerezeka zokhala ndi malipoti oyesa mphero ogwirizana ndi kutentha kwapayekha—ndikusunga ma rekodiwo kwa zaka 15.
Tsogolo liri la mafakitale kumene mchenga sungokhala ndi mawonekedwe-zimanenanso. Kumene kuponyera si sitepe mu ndondomeko, koma maziko anzeru pa chirichonse chotsatira. Izo siziri zokha. Ndicho chitsimikizo.
