Apo mainjiniya anotsanangura 420 simbi isina tsvina nokuda kwezvakapfekwa zvakakwirira, zvinodzivirira ngura—zvakadai semiviri yevharuvhu yehydraulic, pombi shafts, kana kuti mawinch center rollers—zvinoda zvinopfuura kungoteerera zvinhu. Vanoda a 420 fekitari yesimbi isina tsvina iyo inonzwisisa kuti kurapwa kwekupisa kunokanganisa sei kuoma, machining parameters anokanganisa kutendeseka kwepasi, uye nei kugadzikana kwedimensional pasi pekupisa bhasikoro kunonyanya kukosha kupfuura katalog yekusimba kwega.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakagadzira, yakabata kupisa, uye yakaongorora pamusoro pegumi nembiri, 000 tsika 420 simbi isina tsvina kubva 2018-kunyanya kuNorth America oilfield pombi OEMs uye European hydraulic system integrators. Isu takazvionera pachedu kuti kusapindirana kwe annealing kunotungamira sei kudiki-kutsemuka panguva yekupedzisira kugaya. Isu takagadzirisa GD&T callouts yaifungidzira isotropic shrinkage-asi 420 SS castings hazviite saizvozvo mushure mekudzima. Uye isu takagadziridza madhirowa uko "kupedzisa kwegirazi" kwakatsanangurwa pasina kutsanangura Ra miganhu-kungowana chikamu chakakundikana kuyedzwa munyu-spray pamaawa makumi mapfumbamwe nematanhatu nekuda kwekusagadzikana kwepasi pasi.
Ndicho chikonzero kuvimbika kunotanga nguva refu isati yatanga chip inobhururuka. Maitiro edu anotanga neakasimirirwa 420 simbi isina simbi mabhiriji-anoteedzera kuguyo bvunzo mishumo musangano ASTM A276 uye AMS 5630. Isu tinoongorora kabhoni yemukati (0.15–0.20%), chromium (12.0–14.0%), uye kuomarara munzvimbo yakavharwa (≤200 HB) tisati tacheka. Hapana batch inopinda mukugadzira isina yakazara makemikari spectroscopy uye macro-etch kusimbiswa. Sei? Nekuti 0.03% kabhoni deviation inoshandura iyo martensite yekutanga tembiricha ne18°C-uye izvo zvinoshandura zvese muku-kuomesa.
Yedu ISO-inopindirana nzvimbo inobata kuzara kwesevhisi: chaiyo CNC kutendeuka uye kugaya (kusanganisira yakawanda-axis contouring kune yakaoma mavharuvhu ports), vacuum kana inodzorwa-muchadenga kuoma (kusvika 52-56 HRC), cryogenic kudzikamisa, uye yakanaka-grit polishing kana electropolishing yenzvimbo dzakakomba dzekuisa chisimbiso. Isu tinobatanidza kurapwa kwekupisa zvakananga muchirongwa cheNC-hapana vatengesi vekunze, hapana handoffs, hapana gapu rekutevera. Kana mutengi achida 54±1 HRC papfudzi repiston ye32-mm, tinoyera kuomarara panzvimbo nhatu dzeradial *uye* kudzika-profile iyo-kwete chete pamusoro. Izvo hazvigone kutaurirana kune zvikamu zvinomhanya pa3,000 psi ne150,000-kutenderera kuneta kwehupenyu zvinodiwa.
- Hapana off-the-sherufu stock: Yese 420 Stainless simbi odha inogadziriswa kubva kune yakasimbiswa mbishi zvinhu-kwete yakanyungudutswa zvimedu kana kunze zvisina certified.
- Hapana dimensional guesswork: Zvese zvakakosha maficha akasimbiswa uchishandisa maZeiss CMM akarongedzerwa kune NIST-anoteedzera zviyero; GD&T yakaturikirwa zvizere, kwete kungoyerwa
- No bofu kupedza: Surface roughness (Ra, Rz, Rpk) yakasimbiswa neASME B46.1-isati yapera uye mushure mekuita-kuti ive nechokwadi chekushanda kwekusagadzikana
- Hapana kukundikana kwepoindi imwe chete: Yakazara yakawanda traceability-kubva kunhamba yekupisa kuenda kune yeanoshanda ID kusvika yekuongorora timestamp-yakaiswa muERP yedu.
Vamwe vanogona kukakavara kuti kukanda 420 simbi isina tsvina haishande nekuda kwengozi inopisa yekupwanya. Isu tinobvumirana-kana iwe ukashandisa jecha kukanda neyakajairwa gedhi. Asi yedu yekudyara-yakakanda 420 SS dzimba dzepombi inonyudza inomhanya zvisina chikanganiso musevhisi yemvura yegungwa nekuti isu tinodzora gwara rekusimba, shandisa ceramic shell molds ine yakaderera-silica binders, uye kuisa preheat gradients inoderedza kupisa kwemhepo ne40%. Haasi mashiripiti. Kuranga kwemetallurgical kunotsigirwa nemakore gumi nerimwe eruzivo rwecobalt-alloy-apo kutungamira kwekupisa kuri kugadzira-kana-kupwanya.
Isu tinoziva zvakare izvo 420 simbi isina * isingaite * zvakanaka-uye isu tichakuudza pamberi. Izvo hazvienderane ne316 SS mune chloride pitting kuramba. Hazvina kunaka kuti urambe uchiratidzwa pamusoro pe600 ° F. Uye kana dhizaini yako ichida kudzika, kutetepa-madziro kuruka pachikamu chakaomeswa, isu tichapa zano repashure-kupisa-kupisa shinda-kugaya pane kudzingirira matepi anotsemuka pa48 HRC. Transparency haisi mutemo pano. Injiniya hutsanana.
Kune vatengi vanoisa maodha ekutanga-chinyorwa, ongororo yedu yeinjiniya inosanganisira yemahara manufacturability mhinduro: kuona kusimuka kwekushushikana mukuchinja kwemafillet, kusimbisa kuomarara kwezvikamu zvakayambuka> 25 mm, uye nzvimbo dzinoratidza mureza uko electropolishing inogona kusimudza maokisi epasi panzvimbo yekuabvisa. Takadzivirira 23 tooling revisions mumwedzi 18 yapfuura-kwete nekuti "hongu," asi nekuratidza chaizvo panogara njodzi.
Kana iwe uchitsvaga 420 fekitari yesimbi isina tsvina vanodyidzana nemishini-yakakosha maindasitiri zvikamu, tarisa kupfuura zvitupa. Bvunza kuti vanosimbisa sei kuomarara maprofiles. Bvunza sampuli mamicrographs e-etched cross-sections. Bvunza kuti vanobata sei misiyano yakawanda-kune-yakawanda mukunaya kwechromium carbide. Zvadaro enzanisa mhinduro.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inovaka hupenyu hurefu-kwete chete mazuva ekutumira. Yedu inotevera tarisiro: kuwedzera AMS 5630-inoenderana 420 SS kugona kweaerospace actuator housings uye kuvandudza hybrid casting-machining workflows iyo inocheka nguva yekutungamirira ne35% pasina kupira zviyo zvekugadzirisa chimiro. Zvinhu hazvina kuchinja. Asi isu tinotora zvakakomba sei maitiro ayo-ndizvo zvinosiyanisa mutengesi.
