Pamene nyumba ya pampu ya hydraulic ikulephera pa bar 350, kapena phokoso la cobalt-alloy likung'ambika panthawi yotentha, chifukwa chake sichimapangidwira - ndikuchita kukhulupirika. Dimensional drift of ± 0.008 mm mu pistoni cylinder bore siyambitsa ma alarm pamapepala. Zimayambitsa kuwonongeka kwa chisindikizo m'munda. Ichi ndichifukwa chake mainjiniya omwe amapeza zida zamafakitale olekerera kwambiri samasaka "masitolo a CNC." Iwo amafufuza kwambiri mwatsatanetsatane makina fakitale-imodzi yomangidwira osati kulolerana, koma zotsatira zake.
Kumene Kukhazikika kwa Micron-Level Kumakumana ndi Ntchito Yofunika Kwambiri
Kukonzekera kolondola kwenikweni sikukhudza kugunda ma callout a GD&T pa lipoti la CMM. Ndi za kugwira geometry * kudutsa kutentha *, kusunga microstructure *kupyolera mu multi-axis mphero *, ndi kutsimikizira kukhulupirika pamwamba *pamene dzimbiri amakumana abrasion*. Tawona makasitomala akukana magawo omwe adadutsa macheke onse - chifukwa kupsinjika kwapansi panthaka kuchokera kumayendedwe osagwirizana ndi zida kumayambitsa kutopa msanga mu matupi a AMS 5387 cobalt alloy valve. Ichi ndichifukwa chake mphamvu yamphamvu kwambiri mu danga ili si masipingo othamanga kapena mapulogalamu atsopano. Ndi kuphatikiza koyima: kuponyera, kutentha, kukonza, ndi kumaliza pansi pa dongosolo limodzi labwino-osati kuperekedwa kwa ogulitsa atatu.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., valavu iliyonse yamagetsi, maziko a pampu, kapena chodzigudubuza cha winch center shaft imayamba ndi certified T800-grade cobalt-nickel billet-osati generic "superalloy" stock. Kufufuza zakuthupi si bokosi loyang'ana; ndi zolemba zazitsulo zomangika ku gawo lililonse lomalizidwa. Wogula akatchula AMS 5387, amapeza AMS 5387-osati analogi yapafupi yokhala ndi 0.3% yochepa ya chromium komanso kuuma kotentha kosokoneza. Chilango chimenecho chimakhala ndi makina: palibe kukonzanso, palibe "kupambana komaliza" kunyengerera. Multi-axis contouring of cylinder housings zimachitika pakakhazikitsidwe kamodzi. Kuchiza kwa kutentha kumatsatira ndondomeko zowuma komanso zoziziritsa - osati ndondomeko za kupezeka kwa ng'anjo. Zomaliza zam'mwamba zimagwira ntchito, osati zodzikongoletsera: Ra 0.4 µm samayikidwa kuti akwaniritse pepala. Zimanenedwa chifukwa zimachepetsa kukokoloka kwa cavitation m'njira zamadzimadzi othamanga kwambiri.
Chifukwa chiyani "Kulondola" Kokha Sikokwanira-Ndipo Zomwe Zimalephera Popanda Kuphatikiza
Ena angatsutse kuti malo abwino kwambiri a CNC okha amathetsa zovuta zololera. Koma tidawona mapulojekiti ambiri akuyimitsidwa pomwe ma projekiti afika mosagwirizana ndi momwe amapangira tirigu - kukakamiza akatswiri amakina kuti athamangitse kukhazikika m'malo mougwira. Kapena pulagi ya cobalt yosakhala wamba ikadutsa kuzizira, ndiye imasokoneza 0.015 mm itatha kuyika chifukwa cha kupsinjika kosalamulirika kotsalira pamasitepe am'mbuyomu. Kulondola popanda kuwongolera ndondomeko ndi zisudzo.
Apa ndipamene luso lophatikizika lopangira makina limasintha zotsatira. Mchenga ndi kuponya ndalama sizowonjezera pano-ndizolowera zovomerezeka. Nyumba zokhala ndi ma cylinder zomangika molunjika zimachepetsa porosity yamkati chida choyamba chisanakhudze chitsulo. Kuponyedwa kwachitsulo kumathandizidwa kuti zichepetse kupsinjika * musanapange * mwankhanza—osati pambuyo pake. Chilichonse chimadyetsa chotsatira: kuponyedwa kocheperako kumadziwitsa kapangidwe ka CNC; Kutentha kumawongolera mamapu akuwongolera njira zomaliza; zomaliza zomaliza zimayendetsa magawo a post-machining etching. Chotsatira? Pampu ya pisitoni yomwe imakhala ndi ± 0.005 mm kuzungulira kupitirira 300 mm kutalika-ngakhale pambuyo pa maola 48 a 200 ° C kutentha konyowa.
Kulimba Kwambiri Padziko Lonse: Kuchokera Kujambula Ndemanga mpaka Kudzipereka Kutumiza
Akatswiri samasowa wogulitsa wina yemwe amati "inde" pazojambula zilizonse. Amafunikira yemwe amawonetsa mikangano ya GD&T *asanadule* zitsulo. Ku QINGDAO QIANGSENYUAN, kuwunika kwathu kwa uinjiniya kumaphatikizapo zinthu zitatu zomwe sizingakambirane: Choyamba, kuyang'ana ma data osagwirizana omwe amakakamiza kukonza kosatheka. Chachiwiri, kutsimikizira makulidwe azinthu motsutsana ndi zofunikira zochepa za khoma kuti asindikize mwamphamvu kwambiri. Chachitatu, kuwunika ngati kumalizidwa komwe kwafunsidwa kungathe kukwaniritsidwa *popanda* kuchotsa kuya kwa vuto lotenthedwa ndi kutentha. Tabweretsanso zojambula zokhala ndi chizindikiro chomwe chikuwonetsa komwe kulolerana kwa ± 0.003 mm pamalo opindika kungafune kuyikanso ma axis asanu - komanso momwe kusinthira ku ± 0.005 mm spec ndi kuwongolera koyendetsedwa kumapereka ntchito yofananira pamtengo wotsika wa 30%.
Izi sizongoyerekeza. Pamisonkhano yapampopi ya ku Europe ya OEM yomanga pansi pa nyanja, tidachepetsa nthawi yotsogolera ndi 22% pophatikiza nozzle ya nickel ya cobalt, pulagi, ndi kupanga nyumba pansi pa denga limodzi-kuchotsa kuchedwa kwa QA pakati pa fakitale ndi chiwopsezo cha kuwonongeka kwa sitima. Ku North America hydraulic systems integrator, tinkapereka ma valve 120 m'milungu isanu ndi itatu - osati 16 yomwe tinalonjezedwa kwina kulikonse - potsekera m'mabache oyambirira ndikuyendetsa mitsinje yofananira ndi kupanga makina. Kutumiza si tsiku pa spreadsheet. Ndi mndandanda wa ma checkpoints otsimikiziridwa: ma cert azinthu omwe akubwera, ma CMM akuwunika pa 30% ndi 70% kumaliza, kuyesa komaliza kogwira ntchito motsatiridwa motsatizana.
Kuyang'ana M'tsogolo: Kulondola Monga Njira Yamoyo
An kwambiri mwatsatanetsatane makina fakitale sichiyima. Zofuna mawa sizikhala zololera zokha zokha-zikhala zigawo zosakanizidwa pomwe ma microstructures amayenera kulumikizidwa mosasunthika ndi zida zamakina, kapena pomwe zida zopangidwa ndi zowonjezera zimalola ma geometries zosatheka ndi kuyika kwachikhalidwe. QINGDAO QIANGSENYUAN ikuzama R&D mu njira zosakanizidwa zoponya makina, makamaka panjira zovuta zamkati zamapampu. Tikukulitsa ma certification kupitilira ISO 9001 kuphatikiza AS9100 yazinthu zofunikira kwambiri zakuthambo ndi API Q1 ya zida zamafuta ndi gasi - chifukwa kuyamikiridwa sikupitilira patsogolo. Ndi umboni wakuti kulondola kumapangidwira mu dongosolo, osati kumangiriridwa pazomwe zimatuluka.
Ngati ntchito yanu ikuyenda pa bar 350, imazungulira -40 ° C mpaka +200 ° C, kapena imagwira slurry 24/7 - simukusowa "zabwino." Mufunika kutsimikizika kwa mbali. Zolosera zam'mapangidwe. Kusasinthika kwazitsulo. Izo sizimapangidwa. Zimamangidwa-gawo ndi gawo, ndondomeko ndi ndondomeko, chisankho ndi chisankho.
