Kana mainjiniya ataura zvikamu zvesimbi zvakakandwa zvemapombi ehydraulic kana mawinji emotokari yeinjiniya, havangodi "giya." Vanoda dimensional kugadzikana pasi pe350-bar pressure. Microstructure kutendeseka mushure me10,000 kutenderera kwe torsional mutoro. Kupedzisa kwepamusoro kunopesana neabrasive slurry pasina micro-pitting. Ndicho chikonzero kutsvaga kubva kune chokwadi simbi giya zvikamu fekitari-kwete general foundry kana contract machinist-haigone kutaurirana.
PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Takagadzira 17,000 cast iron gear housings for piston pump assemblies kubvira 2019. Takaona zvinokundikana: magiya ane graphite nodule clustering pedyo nemudzi wezino; zvikamu zvinopisa zvinopisa zvakakurumidza uye zvakatsemuka panguva yekukuya kwekupedzisira; ma castings akadururwa neasingaenderane kutonhora mazinga ayo akamonyoroka mushure meCNC contouring. Chinoitika chaichoicho—kwete mabhurocha—chinoumba nzira yatinoita nayo odha iri yose.
Simba redu rinotanga nekubatanidza kwakatwasuka. Vazhinji vatengesi vanoburitsa kunze kukanda, kugadzira, kana kupedzisa. Isu tinodzora ese ari matatu mune imwe ISO-inoenderana nzvimbo muQingdao. Izvi zvinoreva kuti hapana handoffs pakati pevatengesi-uye hapana mikaha mukuteedzera. Kana mutengi achitumira madhirowa eGD&T kune inotakura giya rinoshandiswa kumahombekombe emafuta & gasi madhaka pombi, timu yedu inosimbisa giredhi yezvinhu (ASTM A48 Kirasi 30 vs. Kirasi 40), inoteedzera kuomarara kunyura mujecha mold, zvirongwa zvakawanda-axis CNC nzira dzekubata ± 0.015 mm pane kuomarara kwekupedzisira, uye kuoma-kuoma (220–260 HB) ine macalibrated Rockwell testers. Yese nhanho inosungirira kumashure kune imwechete batch nhamba, yakafanana kupisa kupisa log, yakafanana CMM chirevo.
Isu tine hunyanzvi mumashandisirwo uko kutadza isiri sarudzo. Funga nezvezvikamu zvepombi zvecobalt-alloy senge AMS 5387 magiya kana T800-based center shaft rollers for onboard winches. Izvi hazvisi kunze kwe-pasherufu zvikamu. Vanoda chaiyo graphite morphology kutonga mune base iron cast, inoteverwa nekusimba-kushivirira kugaya kwemainvolute profiles uye yakaoma kubereka nzvimbo. Isu tinoshandisa girinhi-jecha kukanda kusimba kwechimiro, tozopedzisa-guyo giya mazino pamichina 5-axis ine Renishaw kuongorora-hapana kurongeka kwemaoko. Vatengi muNorth America neGermany vanosimbisa: goho redu rekutanga pazvikamu izvi avhareji 94.7%, kwete indasitiri yakajairwa ye72-78%.
Vamwe vanogona kupokana kuti mudzimba dzeUS kana EU dzakawanikwa dzinopa kukurumidza kutungamirira nguva. Asi apo European OEM yaida makumi mana nemaviri ekumanikidza mavharuvhu simbi muQT450-10 ductile iron-ine gumi nemaviri akakosha mabhora anoda ± 0.01 mm kushivirira kwenzvimbo-takaunza mumazuva makumi maviri nemasere. Sei? Nekuti yedu yekukanda-machining hybrid process inobvisa kugadzirisa zvakare. Isu tinokanda padhuze-mambure maumbirwo ane akasanganiswa locators, tobva tagadzira ese anoshanda nzvimbo mune imwe setup. Hapana chechipiri maoparesheni. Hapana kukanganisa kweshanduro yehurongwa. Kungodzokororwa kurongeka, kwakanyorwa panzvimbo yega yega yekutarisa: zvinopinda zvinhu certs, in-process CMM inoongorora ese zvidimbu zvishanu, yekupedzisira inoshanda bvunzo ine hydraulic pressure cycling kusvika ku400 bar.
- Material traceability: Marekodhi akazara-level-kubva pakuongorora simbi yakanyunguduka kusvika kune yekupedzisira kushata kwepamusoro Ra 0.8 µm kuyerwa
- Hapana "standard" zvibvumirano: Isu tinogadzira isiri-yakajairwa giya reshiyo, helix angles inosvika 32 °, uye hupamhi hwechiso hunodarika 180 mm pasina kupira mazino ekusangana.
- Kusimbiswa kwechokwadi kwenyika: Yese magiya edzimba ngarava ine yakasainwa yekuongorora report inoratidza chaiwo akayerwa kukosha-kwete kungopfuura/kutadza zvitambi
Kana uri kuongorora a simbi giya zvikamu fekitari, bvunza mibvunzo mitatu: Vanogona here kubata 0.02 mm yakazara chiratidzo chekuverenga pane giya blank runout * mushure me* kupisa kurapwa? Ivo vanoita metallographic sampling pane yega yegumi yekukanda mijenya-kana chete panguva yekuongorora? Uye mainjiniya avo anomira GD&T kupokana *asati acheka simbi, kwete mushure mekunge marara agadzirwa? PaQINGDAO QIANGSENYUAN TECHNOLOGY, idzo hadzisi dzekuongorora cheki. Iwo matanho emazuva ese ekufambiswa kwemabasa-akavakirwa mukati meERP kuronga, akaiswa mune yevashandisi rondedzero, uye anosimbiswa nevechitatu-bato maodhita kaviri pagore.
Ramangwana nderevagadziri vanobata kukanda uye kugadzira senzira dzinodyidzana — kwete masevhisi anoteedzana. Tiri kuwedzera R&D kuita mahybrid maitiro: laser-clad giya mazino pane akakandwa simbi substrates, pedyo-net yekudyara kukanda kune yakatetepa-yakavakirwa magiya anotakura, uye AI-akabatsirwa gating dhizaini kuderedza porosity munzvimbo dzakanyanya-kushushikana. Asi kukosha kwanhasi kunoramba kusingachinjiki: kugadzirwa kwetsika kwakavimbika kune zvikamu zvinotakura zvinorema, kuvhara kudzvanywa kwakanyanya, uye kushanda uko nguva dzebasa dzinotambanudzira kusvika kumwedzi gumi nemasere. Kwete nekuti zviri nyore-asi nekuti zvinofanirwa kunge zvakanaka.
