Akatswiri akatchula zitsulo zosapanga dzimbiri za mavavu a hydraulic othamanga kwambiri kapena ma shafts osamva kuvala, nthawi zambiri safika pamlingo wokhazikika. Amafunikira kusasinthika kwapang'onopang'ono, kulimba kwa mawonekedwe apafupi, komanso kukhazikika kwapang'onopang'ono panjinga yotentha-zikhalidwe zomwe zida zachikhalidwe kapena makina amalephera. Ichi ndichifukwa chake magulu opangira ambiri akutembenukira ufa zitsulo zosapanga dzimbiri-osati ngati njira ina, koma ngati yankho loyambira la magawo ofunikira kwambiri a utumwi. Ndipo malo amodzi omwe amakwaniritsa lonjezolo nthawi zonse ndi QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Powder Metallurgy Stainless Steel: Kumene Kulondola Kumakumana ndi Metallurgical Control
Tawonapo makasitomala akubwerera katatu ndi chojambula chofanana cha valavu-choyamba chopangidwa kuchokera ku bar stock, kenaka ndalama-cast, potsiriza zitsulo za ufa (PM) zitsulo zosapanga dzimbiri. Kubwereza kulikonse kunathetsa vuto limodzi koma kumayambitsanso lina: kukonza makina otsalira otsalira m'zigawo zopyapyala; kuponyedwa kunayambitsa porosity pamphambano zoyenda; PM idapereka kachulukidwe kaŵirikaŵiri> 99.5% ndi kufanana kwambewu kudutsa makulidwe a khoma la 0.05 mm. Kusiyanaku sikunali kuchita kokha - kunali kubwerezabwereza pamagulu 500-mayunitsi popanda kuyenerera.
Chitsulo chosapanga dzimbiri cha PM sichimatenthedwa 316L ndikuyitanidwa kuchita. Zimayamba ndi ufa wopangidwa ndi ma atomu opangidwa ndi gasi-omwe nthawi zambiri amakhala 17-4PH, 15-5PH, kapena mitundu yosiyanasiyana ya Cr-Ni-Mo-Cu-yowonetsedwa ku ± 5 µm kugawa tinthu. Ku QINGDAO QIANGSENYUAN, compaction imagwiritsa ntchito makina osindikizira awiri okhala ndi nthawi yeniyeni yowunika kachulukidwe, osati matani osakhazikika. Sintering imachitika m'ng'anjo zopanda vacuum zomwe zimayendetsedwa ndi mame (<-40 ° C) ndi mitengo yodutsa ≤5 ° C / min kuteteza mvula ya chromium carbide. Chotsatira? A chuma ndi zokolola mphamvu 20-30% apamwamba kuposa ofanana anagwira sukulu, ziro mkati voids detectable ndi akupanga kuyezetsa pa 10 MHz, ndi pamwamba roughness Ra ≤1.6 µm monga-sintered-palibe yachiwiri akupera chofunika sanali kusindikiza pamalo.
Chifukwa chiyani "Factory" ili yofunika kwambiri kuposa "Supplier"
Ena ogulitsa outsource sintering. Ena amagwiritsa ntchito makina omaliza okha. A zoona ufa zitsulo zosapanga dzimbiri fakitale ali ndi unyolo wonse - kuchokera pa risiti ya ufa mpaka kuyesa kogwira ntchito - ndipo QINGDAO QIANGSENYUAN amachita chimodzimodzi. Malo awo a Qingdao amaphatikiza mizere ya PM yotsimikizika ya ISO 9001 yokhala ndi ma cell a 5-axis CNC, mavuni otenthetsera omwe ali ndi AMS 2750E, ndi ma labu a metrology okhala ndi CMM omwe amayendetsa makina a Zeiss CONTURA G2.
Kuwongolera koyima kumeneku kumachotsa mfundo ziwiri zolephereka: Choyamba, kufufuza zinthu. Gulu lililonse limakhala ndi ma MTR athunthu - osati kungokhazikika, koma zotsalira za oxygen/nitrogen, malipoti osanthula sieve, ndi zipika zamlengalenga. Chachiwiri, kukhulupirika kwa geometric. Wogula atapempha nyumba ya silinda ya pampu ya piston yokhala ndi ma doko 8 ozizirira, ± 0.01 mm kulolerana, ndi malo omata olimba, gululo lidakonza gawo lobiriwira la geometry, mapu olipira a sinter shrinkage, ndikuwongolera kupotoza kwa kutentha kwapambuyo pa sinter - zonse musanadulire zida.
Ma Applications enieni, Osati Manambala a Catalog
Yang'anani kupyola ma datasheet. Pakutumizidwa kwenikweni, zigawo zawo zosapanga dzimbiri za PM zimathetsa mavuto ena am'munda:
- Mafuta ndi gasi pansi mavavu: AMS 5387 cobalt-chromium alloy nozzles amapirira 120 ° C H₂S malo pamene akusunga mpando wokhazikika pambuyo pa 50,000 kukakamiza kozungulira-kutsimikiziridwa kudzera mu API RP 14D hydrostatic endurance test.
- Makina opangira ma winch center shafts: Zigawo za T800 zochokera ku PM zimathamanga 3 × motalika kuposa zofananira zonyezimira pamayesero othamanga a mchere, chifukwa cha kubalalitsidwa kwa yunifolomu ya carbide kuchotsa njira zovalira.
- Zopopera zothamanga kwambiri: Nyumba zokhala ndi Net-shape sintered 17-4PH zimachepetsa nthawi ya msonkhano ndi 65% motsutsana ndi mapangidwe amitundu yambiri, osatulutsa mpweya pa 450 bar differential pressure.
Izi sizinthu zongoyerekeza. Zotsatira zake zimatsimikiziridwa ndi kafukufuku wamakasitomala-osati zoyeserera za labu zokha.
Zomwe Engineers Ayenera Kudziwa Asanatchule
Zowona zitatu zimapanga mapulojekiti opambana a PM:
- Kupanga kwa sintering poyamba: Undercuts zakuya kuposa 3 × khoma makulidwe amafuna yachiwiri Machining. Utali wocheperako ndi 0.2 mm-osati 0.05 mm ngati EDM. Timalangiza kuwunika koyambirira kwa GD&T pogwiritsa ntchito chithandizo chawo chaulere cha uinjiniya.
- Kukula kwachuma kumasintha pamagulu 250: Pansipa, kubweza zida kumapangitsa PM kukhala wodula kuposa CNC. Pamwamba pa izo, mtengo wonse wofika umatsika 18-22% chifukwa cha 70% kuchepa kwa zinyalala zakuthupi ndi 40% kufupikitsa nthawi zotsogolera.
- Kutsiliza pamwamba sikosankha - kumagwira ntchito: Malo okhala ngati-sintered amakumana ndi ISO 13715 kumadera omwe si ofunikira, koma nkhope zomata nthawi zonse zimatha kugwedezeka + ndi electropolishing mpaka Ra ≤0.4 µm. Palibe kuchotserapo.
Samakankhira PM pomwe siili yake - monga mabulaketi akuluakulu kapena nyumba zocheperako. Kuyikira kwawo kumakhalabe kocheperako: mbali zowoneka bwino kwambiri zomwe kachulukidwe, kukana dzimbiri, ndi kukhazikika kwa mawonekedwe zimalumikizana.
Kuyang'ana M'tsogolo: Kuchokera ku Factory kupita ku Foundry-Machining Hybrid Partner
Malire otsatirawa sali abwinoko a PM osapanga dzimbiri-ndikupanga kosakanizidwa. QINGDAO QIANGSENYUAN tsopano ndi oyenerera Integrated njira: sintering pafupi-ukonde valavu thupi, ndiye kuchita localized laser cladding wa Stellite 6 pamalo osindikizira, kutsatiridwa ndi kumaliza-kutembenuka mu umodzi CNC khwekhwe. Izi zimathetsa kusagwirizana kwa kutentha pakati pa zinthu zoyambira ndi zokutira—chomwe chimadziwika kuti chimachititsa kuti zinthu ziziyenda msanga m'mapulogalamu othamanga kwambiri.
Kwa mainjiniya omwe amawunika ogulitsa, funsani mafunso atatu: Kodi angakuwonetseni zipika zamlengalenga zomwe mwaitanitsa komaliza? Kodi amafufuza mosamalitsa—osati kutsimikizira komaliza? Ndipo kodi apanga mgwirizano wanu wa GD&T musanayambe kukanikiza? Ngati yankho ndi inde kwa onse atatu, mukugwira ntchito ndi a ufa zitsulo zosapanga dzimbiri fakitale-osati wogulitsa wina. Kusiyanitsa kumeneko kumatanthawuza kudalirika pamene ntchito silingasokonezedwe.
