Yepamusoro-inoshanda maindasitiri zvikamu hazvikundike kubva pakusaita dhizaini-zvinotadza kana maitiro enyama, dhizaini kudzora, uye inoshanda mitoro nzira dzinopesana. Ndosaka kutungamira hydraulic system OEMs, oiri yemidziyo yekubatanidza, uye chaiyo vagadziri vepombi vachiwedzera kupfuura kwakajairwa kuumba kana bar-stock machining upfu metallurgy simbi fekitari mhinduro-kunyanya kana zvikamu zvinoda> 1200 MPa kusimba simba, kupfeka kusagadzikana pa500 ° C, kana zero porosity munzvimbo dzakakosha-dzakaoma.
Takazvionera isu: mugadziri wepombi wekuEurope akatsiva dzimba dzejecha-cast cylinder nePM-yakagadziriswa 4605 simbi isina tsvina-uye kucheka kukundikana kwemunda ne73% pamusoro pemwedzi gumi nemisere. Sei? Kwete nekuti poda metallurgy "itsva," asi nekuti inopa microstructural yunifomu hapana ingot-based process inogona kuenderana. Miganhu yezviyo inogara yakanaka uye isotropic. Carbide kugovera kunoramba kwakadzora. Uye shrinkage? Inofanotaurwa mukati me ± 0.02 mm-kunyangwe pa320-mm-diameter dzimba dzine mukati mekutonhodza nzira uye 0.8-µm Ra pamusoro inopera.
Iyo nhanho yekuenderana inoda zvinopfuura kungoita muchina uye sinter choto. Zvinoda kubatanidzwa kwakatwasuka pamatanho matatu asingataurweki: yakasimbiswa yakasvibira poda sourcing, yakavharwa-loop thermal-mechanical process control, uye metrology-backed kusimbiswa-kwete chete pakuongorora kwekupedzisira, asi pachinhanho chega chega kubva pagirinhi density mepu kuenda kuHIP mushure mekurapwa. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., izvi hazvisi zvekufungidzira. Nzvimbo yavo inoenderana neISO muQingdao inoita yakazara-kutenderera PM simbi yekugadzira-kubva gasi-atomized pre-alloyed poda (semuenzaniso, PH13-8Mo, Custom 465®, uye AMS 5387-inoenderana cobalt-simbi mahybrids) kuburikidza neinodziya compaction, vacuum sintering uye kudzvanya pasi peNCHI, contol CNCHI. denga.
Hezvino izvo zvinopatsanura maitiro avo kubva kune akajairwa "PM-anokwanisa" zvitoro:
- Material traceability inotanga hupfu husati hwapinda muhopi: Batch yega yega inotakura CoA yakazara neOES + LECO ongororo, pamwe neSEM/EDS verification yeoxyde content uye particle size distribution (D10/D50/D90 logged per ASTM B822).
- Green chikamu kuperera kunoyerwa-kwete kufungidzirwa: In-line CT scanning inosimbisa density gradients isati yanyura; kutsauka> ± 0.05 g/cm³ inokonzeresa otomatiki gadziriso, kwete nemaoko rework.
- Sinter-HIP haina kutevedzana-inoenderana: Choto chavo chemakamuri maviri-chiviri chinoshanda chinodzorwa nitrogen chikamu chekumanikidza panguva yekunyura, yozochinja yakananga kune argon HIP pa1150 ° C/150 MPa-kubvisa njodzi yeoxidation uye kugonesa pedyo-inoretical density (99.8% TD) muakaoma geometries senge multi-port valve miviri.
- Dimensional kugadzikana kunogadzirwa-kwete kubhadharwa: Ivo vanoisa kushushikana-kuzorodza annealing *mushure me* HIP asi *vasati* vapedza machining, vachishandisa nguva-yetembiricha profiles inosimbiswa nekusarira kunetseka mepu (XRD + gomba-kuchera). Mhedzisiro: warpage inoramba iri pasi pe 0.015 mm pamakumbo episton-refu 200-mm-kunyangwe mushure me3-axis milling yekuvharisa migero uye radial ports.
Vamwe vanogona kupokana kuti PM simbi inodhura zvakanyanya kumberi pane kukanda mari. Asi patakatsvaga mutengo wakazara wemuridzi weTier-1 hydraulic valve housing (ASTM F2997 Grade 3), nzira yePM yakaunza 22% yakaderera mutengo wehupenyu-kwete kubva kune zvakachipa zvinhu, asi kubva kune zvakabviswa zvimedu (kukanda goho: 68%; PM goho: 94%), kuderedzwa kwechipiri mashandiro (hapana kubviswa gedhi, hapana 22 yebasa reMTB rakawedzera kugadziridzwa kwe8), 14,600 maawa mu-high-cycling test rigs).
Iyo chaiyo bhodhoro haisi tekinoroji - ndeye kusevenza kwekushandisa. Tichiri kuwana mafoni svondo rega rega kubva kune mainjiniya achibvunza kuti: "PM anogona kubata yedu 1200-bar kumanikidza spike?" kana kuti "T800-based PM ichachengeta kuomarara mushure mekuita nitriding?" Mhinduro yacho inotsamira pashoma pahupfu uye nezvimwe pakusimba kweketani yese-kubva paupfu morphology kusarudzwa kusvika kuHIP ramp rate-inopindirana nehamvuropu yako inoshanda. Semuyenzaniso: spherical powders anopa nani girini density asi kuyerera kuderera muzvikamu zvitete-madziro; zvimedu zvisina kujairika zvinovandudza kuzadza asi zvinosimudza njodzi dzesimba re ejection. Iko hakuna universal spec sheet. Pane chete mamiriro-anoziva maitiro mepu.
Ndosaka QINGDAO QIANGSENYUAN inomisikidza metallurgists-kwete chete kutengesa reps-mukutanga-nhanho mainjiniya wongororo. Vanozoratidza kusawirirana kweGD&T kusati kwatanga (semuenzaniso, kutsanangura kushivirira kweprofile panzvimbo yakasvibiswa pachinzvimbo chekufona kwechinzvimbo chinofungidzira kugadzikana kwedatum). Ivo vanozokurudzira kutevedzana kwekurapa kwekupisa kunoratidzwa paAMS 5387 yakaenzana-kwete generic "stainless simbi" kutenderera. Uye ivo vachagovera mishumo yeCMM yakasvibirira, matanda eHIP, uye mifananidzo yesimbi-kwete kungopfuura/kutadza zvitambi.
Tichitarisa kumberi, shanduko yakasimba haisi yehupfu hwakatsetseka kana kudzvanywa kwepamusoro-kune hungwaru hwekugadzira yakasanganiswa. Funga: sintered cores ine michini yekuisa chisimbiso ivhu, HIP-yakagadziriswa dzimba dzine embedded strain geji, kana PM-forged mabhiidhi anoenda kunonangidzirwa kusimba simulation isati yatanga kudzvanya sitiroko. Aya haasi maR&D concepts. Iwo mapurojekiti arikuitwa nhasi pazvivakwa zvakaita seQINGDAO QIANGSENYUAN's-uko kugona kwefekitori yehupfu simbi kunosangana nekurangwa kwekugadzira, kwete semasevhisi akaparadzana, asi semugumisiro wakagadzirwa.
Kana yako inotevera high-pressure valve, winch shaft, kana pombi yekugara inofanirwa kuendesa inodzokororwa kuita - kwete kungosangana nedhirowa - hausi kusarudza mutengesi. Iwe uri kusarudza mudiwa wekugadzirisa ane metallurgical rigor inoenderana neyako yekushanda njodzi profiles. Izvo zvinotanga nekubvunza mibvunzo yakakodzera-kwete nezve mutengo pa kilogiramu, asi nezvegirini density kudzokorora, HIP cycle yekusimbisa marekodhi, uye mabatiro avanoita kunze-kwe-spec okisijeni yemukati mune inouya poda mijenya. Nekuti mumishoni-yakakosha maapplication, muganho wekukanganisa unogara mune microstructure-kwete bhurocha rekushambadzira.
