Akatswiri akamanena za silika sol mwatsatanetsatane kuponyedwa kwazitsulo zolondola kwambiri, samangosankha njira - akusankha malo odalirika. Kuponyedwa kwa silika sol kumapereka kulekerera kwa ± 0.05 mm, pamwamba kumatha mpaka Ra 1.6 μm, komanso kukhulupirika kwa mawonekedwe apafupi ndi zida zomwe zimagwira ntchito pansi pa 350 bar hydraulic pressure kapena 600 ° C matenthedwe apanjinga. Kusasinthasintha koteroko sikumachokera kuzinthu zamakono. Zimafunika kuphunzitsidwa bwino, kukhwima kwa metrology, komanso chidziwitso chakuya cha alloy-makamaka ndi magiredi a faifi a cobalt monga AMS 5387 ndi T800.
Chifukwa chiyani silica sol-osati galasi lamadzi kapena phosphate-amapambana ma geometri ofunikira kwambiri
Silica sol imapereka maubwino atatu osagwirizana ndi zomangira zina: kukhazikika kwamafuta pamwamba pa 1,100 ° C, zotsalira za alkaline ziro pambuyo pothira, komanso mphamvu ya chipolopolo chapadera panthawi yothira zitsulo zotentha kwambiri. Tawonapo magalasi amadzi akuphwanyidwa panthawi ya chithandizo cha kutentha pambuyo poponyedwa pamene kuzizira kumadutsa 1.2 ° C / sec. Zipolopolo za silika zimakhala ndi kukhulupirika kwapang'onopang'ono m'mizere imeneyi-yofunikira kwambiri popanga nyumba za silinda zapampu ya piston pomwe makulidwe a khoma sayenera kukhala pansi pa ± 0.12 mm kudutsa 320 mm mainchesi. Kuwoneka kocheperako kwa binder kumathandiziranso kubwereza kwa 0.3 mm-wide coolant grooves mu nozzles za cobalt alloy - zomwe sizingatheke kuwonjezera positi popanda kusokoneza moyo wotopa.
Kuphatikiza kwa vertical si buzzword-ndi njira yokhayo yowongolera kukhulupirika kwa microstructure
Othandizira ambiri amapangira kunja, kukonza, kapena kumaliza. Izi zimapanga mipata: 0.08 mm chiwongoladzanja pazitsulo zoponyera zitsulo zimakhala 0.15 mm pambuyo pa makina ovuta chifukwa cha kuvala kwa zida zosajambulidwa; kutentha kumasokoneza kukula chifukwa wogwiritsa ntchito ng'anjo alibe chojambula choyambirira cha GD&T. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., magawo onse amachitika pansi pa denga limodzi logwirizana ndi ISO. Tikaponyera gawo la mpope la AMS 5387, akatswiri athu azitsulo amatsimikizira ma cert aiwisi asanasungunuke. Makina athu amtundu wa CNC amapangidwa mwachindunji kuchokera komwe akuponyedwa pogwiritsa ntchito malupu a CMM okhala ndi fixture-palibe kukonzanso. Kugaya pamwamba kumatsatira pambuyo pochepetsa kupsinjika, kutsekeka mopanda phokoso mkati mwa 0.005 mm kutalika kwa 450 mm. Kupitilira kumeneko kumachotsa zolakwika zochulukirapo-ndikufotokozera chifukwa chake 92% yamisonkhano yathu yokakamiza imayesa kuyesa koyambira.
Zochitika zenizeni zapadziko lapansi zimayamba ndi kutsimikizira kwa alloy-specific process
Cobalt-nickel alloys sakhala ngati 316 zosapanga dzimbiri. Mlingo wawo wowumitsa ntchito umakwera pambuyo pochotsa zinthu 15%. Kutentha kwawo ndi 30% kutsika kuposa chitsulo cha carbon - kotero kudula kwamadzimadzi kuyenera kugunda ndondomeko yeniyeni ya zida kapena kusungunuka komweko kumachitika. Timajambula chigawo chilichonse cha T800 mulaibulale yathu yantchito: ma spindle RPM, mitengo yazakudya pagawo lililonse, ngakhale ma angles ozizirira. Pa mapulagi a aloyi a cobalt okhala ndi makulidwe a khoma la 0.8 mm, timagwiritsa ntchito mphero zomaliza za 0.3 mm carbide pa 18,000 RPM ndi 80 mm/min feed-zigawo zomwe zatsimikiziridwa pazaka 127 zoyeserera. Makasitomala omwe amatibweretsera zojambula zakale nthawi zambiri amafunsa kuti: "Kodi mungagwire ±0.03 mm apa?" Yankho lathu sizongoyerekeza. Zimatengera data yoyezedwa kuchokera ku geometry yofananira mu chipika chathu chopanga-monga gulu la winch center shaft roller pomwe malipoti a CMM adawonetsa kupatuka kwakukulu kwa 0.022 mm kudutsa mayunitsi 1,200.
Kusankha fakitale yopangira silika kumatanthauza kufunsa mafunso atatu
- Kodi ali ndi mankhwala awo otentha ndi kumaliza? Njira zakunja zimachotsa kutsata. Ngati maziko anu a pampu akulephera kuyesa kugwedezeka, kodi wogulitsa angatsimikizire kuti kutentha kwake kwagwiritsidwa ntchito - ndikugwirizanitsa ndi malo osungunula oyambirira?
- Kodi amapanga zinthu zofunika kwambiri pakukhazikitsa kumodzi? Kukonzekera kumayambitsa kusuntha kwa kuyanjanitsa. Yang'anani malo okhala ndi ma cell a CNC amitundu ingapo omwe amatha kupitilira popanda kuchotsedwa.
- Kodi amasindikiza zidziwitso zenizeni zoyendera - osati kungonena za "ISO certified"? Funsani zitsanzo za malipoti a CMM owonetsa zopatuka zenizeni motsutsana ndi ma callout a GD&T. A zoona silika sol mwatsatanetsatane kuponya fakitale amagawana nawo-osati kubisala kuseri kwa ziphaso.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amayankha kuti inde onse atatu. Mayendedwe ake ophatikizika, mamapu a alloy-enieni, komanso kutsata kwathunthu kumapangitsa kuti ikhale mnzake wobwereza wa North America hydraulic OEMs ndi opanga zida zamafuta aku Europe. Chotsatira? Zigawo zomwe zimagwirizana - osati pamapepala okha - koma muutumiki. Pamene makina opangidwa ndi makina osakanizidwa akukwera, kusiyana pakati pa "castable" ndi "precision-cast" kumakula. Ntchito zolumikizidwa moyima, zophatikizidwa ndi metrology zimalumikiza.
