Mainjiniya akamatchula kuponyedwa kwachitsulo kolondola kwa mavavu othamanga kwambiri a hydraulic kapena zida zapampu za cobalt-alloy, samangofunika fakitale yamakampani opanga zitsulo- amafunikira imodzi yomwe imayang'anira kukhazikika kwapang'onopang'ono ngati nthawi ya mgwirizano ndi kusasinthika kwazitsulo ngati ndime yosagonja.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ndi bwenzi loterolo. Kutengera ku Qingdao, China, kampaniyo sipereka luso lake lalikulu. Imaponyera, makina, kutentha kutentha, kuyang'ana, ndi zombo-kuchokera ku malo amodzi ogwirizana ndi ISO kumene nyumba iliyonse ya valve yokakamiza imayambira ngati ingot yovomerezeka ya AMS 5387 cobalt alloy ndipo imatha ndi CMM yotsimikiziridwa GD & T kutsata mpaka ± 0.01 mm.
Chifukwa chiyani luso lazinthu limalekanitsa kuponyedwa kolondola ndi kupezeka kwazinthu
Tawona magulu ogula zinthu akutaya milungu itatu - ndi $ 42,000 pokonzanso - chifukwa gulu "lovomerezeka" la T800 linalibe kubalana kwa carbide. Imeneyo si nkhani ya makina. Ndi kulephera kwa mgwirizano wazinthu.
QINGDAO QIANGSENYUAN amapewa izi popanga limodzi zinthu zopangira ndi ogulitsa ovomerezeka. Loti iliyonse ya AMS 5387 cobalt-nickel imatsimikiziridwa ndi spectrographic * isanasungunuke. Mphuno iliyonse yochokera ku T800 imalandira kutsimikizika kwa microstructure kudzera muzitsulo za optical-osati kuyesa kuuma kokha. Chotsatira? Mphamvu zamakokedwe zobwerezabwereza (≥1,250 MPa), kulimba kwa Rockwell C62-65 mosasinthasintha m'magawo opingasa, ndi kusiyanasiyana kwa zero batch-to-batch pakukulitsa kwamafuta.
Izi sizongoyerekeza. Mu projekiti yaposachedwa ya malo opangira mafuta ku North America, pulagi yawo ya cobalt alloy idagwira 15,000 psi pa 280 ° C kwa miyezi 18 popanda kuwononga - pomwe ogulitsa awiri omwe akupikisana adalephera mkati mwa masiku 90 pansi pamiyeso yofanana. Kusiyana kwake? Kuwongolera malire a mapira panthawi yopangira ndalama, osati kuchiritsa pambuyo pokonza.
Kuphatikizika koyima komwe kumachotsa kulolerana kwapang'onopang'ono
Zonena zambiri za "malo oyimitsa" zimagwera pamawonekedwe apakati pakupanga ndi makina. Mchenga-cast nyumba amazungulira nthawi ya CNC fixturing. Kuyika kwa ndalama kumasokonekera panthawi ya chithandizo cha kutentha. Dimensional drift imachulukirachulukira.
QINGDAO QIANGSENYUAN amachotsa handoffs amenewo. Malo awo amayendetsa ndalama zopangira ndalama, makina asanu ndi limodzi a CNC, chithandizo cha kutentha kwa vacuum, ndi kumaliza kwa electropolished - zonse pansi pa denga limodzi, panjira imodzi yolumikizirana. Nyumba ya silinda ya pampu ya pistoni imachoka papatani ya sera kupita ku gawo lomaliza popanda kusiya malo opangira. Palibe mayendedwe akunja. Palibe kukonzanso. Palibe kusuntha kwa recalibration.
Zotsatira zake? Miyendo ya Cylinder imakhala yozungulira ≤0.008 mm kudutsa 320 mm kutalika. Nkhope za Flange zimasunga kufanana mkati mwa 0.012 mm. Ndipo ma callout ovuta a GD&T-monga kulolerana kwamabowo oyika mipando ya vavu-amatsimikiziridwa *mumchitidwe*, osati pakuwunika komaliza.
- Ma valve opanikizika: ASME B16.34-yogwirizana, yokhala ndi zolemba zoyeserera za hydrostatic zotsatiridwa ndi nambala ya kutentha
- Maziko a pampu: FEA-yovomerezeka kuti igwire ntchito 5x, mchenga woponyedwa mu QT400-18 wokhala ndi malo opangidwa ndi makina mpaka Ra 0.4 μm
- Winch center shaft rollers: Kupyolera mu 42CrMo4 yowumitsidwa, pansi mpaka ± 0.005 mm kutalika kwa 1.2 m kutalika
Kuwongolera kwaubwino kumapangidwira pakayendedwe kantchito-osati kumangiriridwa pambuyo pake
"Timayang'ana chilichonse" zikumveka zolimbikitsa - mpaka mutaphunzira dongosolo lawo loyendera limafuna macheke 17 olembedwa pagawo lililonse la cobalt alloy, kuphatikiza zotsimikizira zazinthu zitatu: billet yomwe ikubwera, kuponyera, ndi chithandizo chamankhwala pambuyo pa kutentha.
Chigawo chilichonse chimakhala ndi kutsatiridwa kwathunthu: nambala ya kutentha, malo oponya, mtundu wa pulogalamu ya CNC, ID ya ogwiritsa ntchito, sitampu ya lipoti la CMM, ndi data yoyezera kumapeto. Palibe "chitsanzo". Palibe chomwe "chimaganiziridwa." Ngati kasitomala apempha kuti ayesedwenso pagawo lotumizidwa, QINGDAO QIANGSENYUAN imakoka mbiri yoyendera yoyambirira—osati chidule chachidule.
Chilango chimenecho chimafikira ku mgwirizano wa mainjiniya. Pamene OEM yapampope yaku Europe idatumiza zojambula zololera mosadziwika bwino pamphuno ya cobalt alloy, gululo silinadikire kuti limveke. Adachita nawo kafukufuku wopangidwa, adawonetsa mikangano itatu ya GD&T, adaganiza zowongolera zina zogwirizana ndi ISO 1101, ndipo adapereka ndemanga pasanathe maola 48 zida zisanayambe.
Kusankha fakitale yanu yotsatira yopanga zitsulo kumatanthauza kusankha mbiri yanu yowopsa
Mashopu otsika mtengo amapereka magawo. Othandizira olondola amapereka zolosera. QINGDAO QIANGSENYUAN imagwira ntchito pamphambano zazitsulo, metrology, ndi ntchito yofunika kwambiri - pomwe kupatuka kwa 0.02 mm sikuli "kulekerera pang'ono" -ndikuletsa kuyenda, kutulutsa chisindikizo, kapena kutopa kowopsa.
Cholinga chawo si chachikulu. Ndi maopaleshoni: makina opangira ma hydraulic, zida zamafuta & gasi, ma winchi amagalimoto aumisiri, ndi misonkhano yapadera yamapampu. Kukula kocheperako kumathandizira chidziwitso chakuya-monga kudziwa momwe cobalt alloy shrinkage imayendera mumitengo yopyapyala yamakhoma, kapena momwe chitsulo choponyera mchenga chimayankhira pakudulidwa kosokoneza panthawi yamphero.
Ngati ntchito yanu ikufuna kubwerezabwereza - osati kungotsatira - ngati mapangidwe anu amadalira kukhulupirika kwa microstructure monga geometry, ndipo ngati nthawi yanu imadalira kupambana koyamba, ndiye kulondola. fakitale yamakampani opanga zitsulo si amene ali ndi mawu otsika kwambiri. Ndi yomwe imayankha "Kodi mutha kugwira ± 0.008 mm pa bore ili?" ndi mapindikidwe a chipukuta misozi—osati lonjezo.
