Nei 17-4PH Fekitori Kudyidzana Kuchikundikana-Uye Magadzirirwo Ayo Imwe Qingdao Chikwata Zuva Nezuva
Mazhinji mainjiniya anotsvaga 17-4PH zvikamu anorova madziro mamwe chete: mutengesi anovimbisa H900 simba uye ASTM A564 kutevedzera, obva aburitsa kuoma kusingaenderane pane batch-kana zvakanyanya kuipa, madiki-diki mushure mekupisa kurapwa. Takazviona mu hydraulic valve housings yakarambwa pakati pegungano, mupiston pombi maoko achitadza kusvika 3,200 psi, muwinch centre shafts achirwa panguva yekukuya kwekupedzisira. Chikonzero chikuru hachisi chinhu chisina kunaka - kugona kwakakamukana. A chokwadi 17-4PH fekitari inofanirwa kudzora simbi, machining, uye kugadzirwa kwemafuta pasi pedenga rimwe. Kwete "kugona"--asi zvakaratidzwa, zvinorondwa, zvinodzokororwa.
Metallurgical Control Inotanga Kusati Kwatanga Machining
17-4PH haingori "simbi isina tsvina ine mhangura." Kuramba kwayo kwekuora uye 1,100 MPa simba rekusimba rinotsamira pane chaiyo yekuchembera kinetics: ipfupi, uye precipitates haiumbe; kwenguva refu, uye dzakakasharara, dzinodzikisira kuomarara. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yega yega 17-4PH billet inosvika iine mill test mishumo-yakasimbiswa kuAMS 5604 kana ASTM A564 Giredhi 630-uye inovhenekwa inouya: spark kuyedza, PMI kuongororwa, uye mhinduro-anneal chip tembiricha isati yachekwa.
Isu hatisi outsource kurapwa kupisa. Yedu ISO-inoenderana nzvimbo inomhanya-inodzorwa-muchadenga mavira ane ± 2 ° C kufanana, ichiteverwa nehelium-yakatonhorera quenching kudzvinyirira delta ferrite kuumbwa. Kuchembera kutenderera kwakaiswa pajeti-kwete pakuchinja-nechaiyo-nguva thermocouple mepu. Mhedzisiro? Kusiyana kwekuoma kunogara mukati meHRC 38–40 yeH900 mamiriro, akasimbiswa pamapoinzi matatu pachikamu uchishandisa Rockwell B neC zvikero. Hapana kufungidzira. Hapana rework.
Precision Machining Inoremekedza Zviyo
17-4PH inoshanda-inoomesa zvine hukasha. Nzira dzematurusi dzakajairwa dzinokonzeresa kukurumidza kupera kweflank, mavanga ekutaura, uye kudonha-kunyanya mudzimba dzakatetepa-silinda kana miviri yakadzika-yakaiswa tambo yekumanikidza. Chikwata chedu cheCNC chinoshandisa nzira dzekugaya dzakakura nePVD-yakavharidzirwa carbide inoisa, inogadzirisa roughing iyo inoderedza radial simba ne35%, uye akaomesesa-toolholding masisitimu akarongerwa zviuru gumi nezviviri rpm spindles.
Isu tinogadzira zvakakosha zvinhu * mushure * kuchembera — kwete kare. Sei? Nekuti post-heat-treat stress relief inoshandura chikamu geometry. A 0.015 mm kushivirira pa 200 mm dhayamita imba haigone kuwanikwa kana iwe ukagaya usati wachembera wobva wakura. Maitiro edu ekuyerera anokiya GD&T zvinodzora kune yekupedzisira mamiriro: kupedzisa kwepamusoro Ra ≤ 0.8 μm pazviso zvakasimwa, kushivirira kwenzvimbo ± 0.02 mm pamakomba anokwirisa, uye concentricity inochengetwa kusvika 0.01 mm pamajenari e shaft-zvese zvakayerwa pane calibrated Zeiss CONTURA Gcoms-CMM tembiricha ine pro pro.
Iko Kukandira Kunosangana Nepamusoro-Simba Alloy Nyanzvi
Zvimwe 17-4PH zvikumbiro zvinoda padhuze-net-shape kuomarara zvisingagoneke nebar stock: asymmetric pombi nheyo, yakasanganiswa yekutonhodza chiteshi mumavharuvhu manifolds, kana akawanda-port cylinder blocks. Ndiko uko kune yedu mbiri-yekugona modhi yakakosha. Isu tinokanda 17-4PH kuburikidza nekutsvaga kwekudyara-kwete jecha-kuti tiwane kushata kwepamusoro zvakaderera seRa 3.2 μm uye kugadzikana kwedimensional mukati me ± 0.3% yehukuru hwezita.
Asi kukanda 17-4PH kunounza njodzi: shrinkage porosity, kupatsanurwa pane dzakakora zvikamu, uye embrittlement kana kutonhora kwemazinga kutsauka kubva pa5-10 ° C/s. Chikwata chedu chekuwana chinotarisisa kusimba nekufungidzira kwekupisa, inogadzirisa gating dhizaini ichishandisa MAGMASOFT simulation, uye inosimbisa yega yega ine ultrasonic bvunzo (ASTM E114) uye macro-etch ongororo. Yese inokandwa inotakura yakasarudzika yekupisa ID yakabatana kune yayo kemikari report, thermal cycle log, uye NDT mhedzisiro - inoteedzerwa zvizere kune raw material batch.
Kusimbiswa Kwepasirese-Kwete Kutevedzera Pepa Chete
Kuteerera hakurevi chinhu pasina mamiriro. Kana European OEM yaida 17-4PH piston pombi silinda dzimba dzemapombi epasi pegungwa, vakatsanangura ASTM A564, H900, uye munyu-spray kuramba ≥1,000 maawa paASTM B117. Asi ivo havana kutsanangura nzira yekubata nayo 12-mm-yakakora flange-to-barrel shanduko-inozivikanwa inosimuka yekushushikana.
Takamhanya neFEA-inotyairwa kuneta modhi, takawedzera pfuti yakadongorera kune fillet radius, uye yakasimbisa hupenyu hwekuwedzera ne500,000-cycle hydraulic pulsation test pa4,500 psi. Zvikamu zvakapfuura. Zvinotonyanya kukosha, vakatumira nehurongwa-nekuti yedu yakaonda kuronga sisitimu inoteedzana kurapwa kwekupisa, machining, uye kupedzisa mukufanana, kwete nhevedzano. Prototype yekutungamira nguva: 18 mazuva. Medium-vhoriyamu (500 pcs): 32 mazuva. Zvese zvine magwaro akazara ePPAP, kusanganisira zvidzidzo zveMSA uye zvirongwa zvekutonga.
Kana purojekiti yako inotevera 17-4PH ichida kutendeseka pasi pekumanikidzwa, kuramba kwecorrosion mune zvehasha midhiya, uye zero kushivirira kune zvekutengesa-cheni zvinoshamisa-tanga nemudiwa anobata alloy sainzi seisingagone kutaurirana, kwete sarudzo. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshanda sechokwadi 17-4PH fekitari: vertically integrated, metallurgically disciplined, uye akagadzirirwa chinangwa-chakakosha kuvimbika. Maitiro avo haangosangana nemaspeciales-anofungidzira kutadza modes chimbo chekutanga chisati chabata simbi.
