Zida za migodi zikalephera kuchulukitsidwa, kutsika sikumayesedwa mu maola angapo - kumawerengedwa mu matani otayika, kuchedwa kutumizidwa, ndi kutsika mtengo kwa kukonza. Othandizira safuna magawo ambiri. Iwo akusowa mbali zoyenera: yokhazikika, yokhazikika mwazitsulo, komanso yotsimikiziridwa mu 300-bar hydraulic circuits kapena abrasive ore-handling winch systems. Ichi ndichifukwa chake opanga ma OEM padziko lonse lapansi ndi Tier-1 akuchulukirachulukira kukhala a migodi zida zigawo fakitale amene amaona sayansi yakuthupi ngati uinjiniya—osati kugula zinthu.
Chifukwa chiyani "Kupangidwa ku China" Sikutanthauzanso "Kunyengerera Pazovuta"
Tazionera tokha: woyendetsa miyala ku North America adalowa m'malo atatu otsatizana a pampu ya cobalt-alloy nozzles kuchokera kwa ogulitsa generic. Chilichonse chinalephera maola 400 ogwirira ntchito asanafike—kung'amba pang'ono pakhosi, kusagwirizana kwambewu ya AMS 5387, kugwedezeka kwakukulu pambuyo pa kutentha. Gulu lachinayi linachokera ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Zinatenga maola 2,170 - palibe kukonzanso, palibe zosintha m'munda. Kusiyana sikunali kokha kukonza makina. Kunali kuphatikizika koyima: kuwongolera kuponya, njira zochizira kutentha kwa aloyi, ndi kutsimikizika kwa CMM pagawo lililonse-osati kungoyang'ana komaliza.
Izi sizongoyerekeza. Malo awo ogwirizana ndi ISO ku Qingdao amayang'anira unyolo wonse: kuyika ndalama kwa matupi oponderezedwa okhala ndi mipanda yopyapyala, kuzungulira kwa CNC kozungulira kwa piston pump silinda nyumba (± 0.015 mm GD&T tolerance), ndi kutsimikizira umphumphu wapambuyo pa makina pogwiritsa ntchito mawonekedwe owoneka bwino. Pamene galimoto yaumisiri ya ku Europe OEM imafunikira zodzigudubuza za winch center shaft zokhala ndi kuzama kwa kesi ≥1.2 mm ndi kulimba kwapakati 32–36 HRC, sanatulutse ndi kupanga makina padera. Anatumiza chojambula chimodzi - ndipo adapeza malo amodzi ovomerezeka, omwe amatha kutenthedwa, okhala ndi ma MTR athunthu ndi malipoti a microstructure.
No-Compromise Alloy Handling-Kumene Mafakitale Ambiri Amayima, Amayambira
Ena mafakitale makina zitsulo zosapanga dzimbiri. Makina a QINGDAO QIANGSENYUAN T800 cobalt-based superalloys —zida zomwe zimagwira ntchito mwachangu kuposa momwe zida zingadulire, zimafuna kusakhazikika kwa kutentha kwa 0.5°C panthawi yoyatsa, ndikukana zoulutsira mawu wamba. Zida zawo zapampu za AMS 5387 cobalt 6 "sizingoponyedwa." Iwo amaponyedwa mu ng'anjo za vacuum-inert atmosphere, zothandizidwa ndi AMS 2750E, kenako okalamba ndi mapu a nthawi yeniyeni ya thermocouple kudutsa gawo lililonse.
Kuthekera kumeneku kumawalekanitsa ndi masitolo ogulitsa zitsulo. Ma aloyi a cobalt-nickel samangokhudza kuuma kokha - amafunikira mvula yoyendetsedwa ndi delta-gawo kuti mupewe kuphulika m'malo otsetsereka kwambiri. Kukalamba kwanthawi yolakwika kumasintha pulagi yapampu kukhala chiwopsezo chogwidwa. Tawunikanso zolemba zawo zopanga: gawo lililonse la T800 limaphatikizapo kusanthula kwa SEM-EDS kutsimikizira kugawa gawo, osati chemistry yochulukirapo. Ndiwo mtundu wa migodi yolimba ya OEM yomwe ikufuna tsopano - osati kutsata, koma kulosera.
Kupanga-Kupereka Chilango—Palibe Zodabwitsa, Palibe Kukonzanso
"Mungathe kuchita izi?" ndi funso loyamba lolakwika. Yoyenera ndi: "Kodi gawo ili * lichita chiyani * m'dongosolo lanu - ndipo chitha kusweka bwanji ngati tingokulitsa mtengo wokha?" Gulu la engineering la QINGDAO QIANGSENYUAN silidikirira ma PO. Amachita nawo powunikiranso kamangidwe - kuyika ma angles osaya kwambiri kuti azitha kuponya mchenga, kutanthauza fillet radii yomwe imalepheretsa kupsinjika mumiyendo yothamanga kwambiri, kutsimikizira kuyimba kwa GD&T motsutsana ndi zovuta zogwirira ntchito.
- Amapeza zovuta zosokoneza zida zisanayambe-kudula nthawi ya prototyping ndi 30% pafupifupi
- Njira yawo yosakanizidwa yopangira makina imachotsa zolakwika zachiwiri zapampu pamaziko ovuta
- Kutumiza kulikonse kumaphatikizanso malipoti am'mbali ogwirizana ndi ASME Y14.5, osati kungodutsa/kulephera masitampu
Izi si zisudzo. Ndilo mayendedwe olembedwa: kutulutsa zojambula → machesi a certification → lipoti loyamba la CMM → kutsimikizira makulidwe a mkati → kuyesa komaliza kogwira ntchito (mwachitsanzo, kuyezetsa kukakamiza pa 1.5 × kukakamiza kugwira ntchito). Palibe chomwe chimatumiza popanda kutsata kwathunthu - nambala ya kutentha, ID ya woyendetsa, ID yamakina, sitampu yoyendera.
Kudalirika Sichinthu. Ndilo zotsatira za Chisankho chilichonse cha Njira.
A odalirika migodi zida zigawo fakitale sichimalonjeza ziro zolakwika. Imatsimikizira kuthetsa kwazoyambitsa - mkati mwa maola 72 - pakusagwirizana kulikonse. Imasunga mapangano amitundu iwiri ndi ogulitsa cobalt alloy kuti kutha kwa mphero imodzi sikuchedwetse kuyitanitsa kwanu. Imakhala ndi ma valve omwe amasokonekera mu AMS 5387 ndi ASTM A48 Class 35 iron-kuchepetsa nthawi yotsogolera kuyambira masabata 14 mpaka 3.
Kuyang'ana m'tsogolo, cholinga chawo cha R&D sichikukweza voliyumu. Zimatengera njira zosakanizidwa: zopangira ndalama zokhala ndi mawonekedwe apafupi ndi ukonde okhala ndi njira zoziziritsa zophatikizika zowongolera matenthedwe pamapampu othamanga kwambiri, komanso makina opangidwa ndi laser a cobalt alloys omwe amadula kuvala kwa zida ndi 60%. Izi sizinthu za labotale. Amatumizidwa ku Southeast Asia zopangira zamkuwa ndi mafuta akunyanja aku Norway & skids-gasi-malo omwe kulephera sikungatheke.
Ngati chisankho chanu chotsatira chikudalira kubwerezabwereza, kukhulupirika kwa alloy, kapena kutumiza panthawi yake zinthu zofunika kwambiri - yambani ndi kuwunika kwaukadaulo, osati pepala lamitengo. Gawo lokwera mtengo kwambiri silo lomwe latchulidwa kwambiri. Ndilo lomwe limalephera kusuntha pakati, kukwiriridwa pansi pa matani 200 a ore.
