Kana mainjiniya achitsanangura kukanda jecha rezvikamu zvesimbi zvakakura-kunyanya muhydraulic masisitimu, oiri uye gasi midziyo, kana inorema-duty pombi maassemblies-havasi kungosarudza maitiro. Vari kusarudza mudiwa anonzwisisa kuti chimiro chezviyo chinokanganisa sei hupenyu hwekuneta, kuti mold compaction inokanganisa sei kudzokorora, uye nei 0.15 mm kushivirira pacobalt-alloy cylinder imba hachisi chikumbiro-icho chisingagone kutaurirana chinodiwa. Ndiko uko ruzivo rwepasirese rwunoparadzanisa vatengesi vanogona kubva kune chokwadi jecha rokukandira foundry fekitari shamwari.
Nei Kukandira Jecha Kuchiri Kukunda kuMishoni-Yakakosha Maindasitiri Zvikamu
Vamwe vanofungidzira kuti kukanda jecha ndekwezvishandiso zvenhaka chete. Asi isu takazviona zvichiunza budiriro inodzokororwa apo mamwe maitiro anokundikana: hombe-chikamu simbi castings inoda kupisa kutyisa kuramba mupombi nheyo; simbi dzimba dzine mukati kutonhora migero hazvibviri kumushini post-cast; zvinhu zvisina tsvina zvinoda isotropic simba mukati mezvikamu zvakakora. Kiyi kudzora-kwete chete pamusoro pekudurura tembiricha kana shakeout nguva, asi pamusoro pecheni yese: girinhi jecha kuenderana, musimboti wekudhinda alignment, gating dhizaini yekuyerera kwelaminar, uye post-cast-yekusimbisa kushushikana kutenderera kunosimbiswa ne strain gauge mepu.
Mune imwe purojekiti ichangoburwa, European OEM yaida makumi mana nemaviri ekumanikidza mavharuvhu miviri muASTM A351 CF8M. Mutengesi wavo wepakutanga akapotsa GD&T callouts pamakomba matatu anokwira eflange-zvichikonzera kukanganiswa kwegungano muyekupedzisira bvunzo rig. Isu takaibata panguva yekudhirowa kusimbiswa, gadzirisa iyo cope pateni dhizaini angle ne 0.8 °, uye tikawedzera yechipiri mold alignment pini. Mhedzisiro: zero rework mukati me120 mayunitsi. Iyo nhanho yekupindira haigoneke pasina yakazara vertical kusanganisa-kubva kusanganiswa kwejecha kusvika kuCNC kupedza machining pauriri humwe.
Apo Hunyanzvi Hwezvinhu Hunosangana NeKurangwa
Cobalt-nickel alloys seAMS 5387 uye T800 haipindure kune generic foundry maitiro. Nzvimbo yavo yakakwira yekunyungudika, kuderera kwemvura, uye nehukasha inopisa kubvarura kuda nzira dzakaenderana: dzakasimba binder ratios, preheated molds pamusoro pe250 ° C, uye inodzorwa kutonhora mitengo inotariswa kuburikidza neyakaiswa thermocouples. Takadurura pamusoro pe1,700 kg yeT800 mumwedzi gumi nemisere yadarika-uye batch yega yega inotakura kuteedzera kuzere: nhamba yekupisa, spectrographic analysis report, uye as-cast microstructure mapikicha anoratidza dendrite ruoko spacing pasi pe25 µm.
Chirango ichocho chinopfuura kubata alloy. Kune masimbi ekukanda anoshandiswa muinjiniya mota winch centre shaft rollers, isu tinosimbisa graphite nodule count (ASTM E2567) uye ferrite/pearlite ratio * isati * machining atanga. Sei? Nekuti 5% pearlite yakawandisa inowedzera nguva yekukuya pamusoro ne37% uye inocheka hupenyu hwemidziyo nepakati. Tinozviyera-kwete kuzvifungidzira.
Izvo "Kururamisa" Zvinonyatsoreva Mukuita
Kurongeka mukukandira jecha hakusi kwekudzinganisa micron-level kushivirira pazvikamu zvakakura. Ndezvekufanotaura. Yedu yakajairika kugona: ± 0.3 mm pane zvinhu zvinosvika 600 mm, ± 0.5 mm pazvikamu zvinopfuura 1,200 mm-ine CMM-yakasimbiswa yekutanga-chinyorwa mishumo inosanganisirwa pasina muripo wakawedzerwa. Asi chinonyanya kukosha ndeye yedu yemhinduro loop: kana dhirowa rako richida kupera kwe 12.5 µm Ra pachibhorani chakagadzirwa, ticharatidza kuti nzvimbo yekukanda ichada 2.1 mm kana 3.4 mm yekubviswa kwestock-uye kuti zvinokanganisa sei kuderedzwa kwemvumo uye kuiswa kwekusimudza.
- Mavharuvhu ekudzvanya: GD&T-inoenderana nechigaro chepamusoro, chakasimbiswa nemhepo gaging uye kuvuza-kuyedzwa pa1.5 × kushanda kumanikidza.
- Piston pombi silinda dzimba: Bore concentricity yakabatwa kusvika 0.025 mm TIR mhiri 450 mm kureba
- Non-standard cobalt alloy nozzles: Kukobvu kwemadziro kusiana kunodzorwa mukati me ± 0.18 mm pa8 mm zvishoma zvikamu.
Isu hatibati kukanda uye kugadzira semadhipatimendi akasiyana. Iwo matanho anotevedzana eimwe maitiro-saka CNC programmer anoongorora as-cast CT scan asati anyora yekutanga toolpath. Ndiwo maitiro aunodzivirira kuwana porosity pasi penyika yakaoma chisimbiso mushure memaawa gumi nemana ekugaya.
Kusarudza Wokuroorana Naye Anounza—Kwete Zvipikirwa Chete
A jecha rokukandira foundry fekitari unofanirwa kupindura mibvunzo mitatu usati wasaina PO: Vanogona here kubata kushivirira kwako kwakanyanya pane yakanyanya kuoma geometry * mukugadzira *, kwete mune prototype chete? Ivo vane zvitupa zvavo zvenyama-kana kuti vanovimba nepepa remupi? Uye kana kutsauswa kwedimensional kukaitika, vanogovana midzi-chikonzero dhata (jecha permeability matanda, melt analysis curves, X-ray density mepu) kana kungoburitsa fomu rekugadzirisa?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshanda pasi pe ISO 9001: 2015 ine zvinyorwa zvekuongorora zvinyorwa zvega rega rekukanda mijenya. Yese yakabikwa mijenya yakasimbiswa, yega yega-yakabikwa-yakabikwa chikamu, chimwe nechimwe chakapedzwa chikamu chinoongororwa pasi pe10 × magnification. Isu tinoshandira vatengi muNorth America, Europe, uye Southeast Asia-kwete kuburikidza nemabhuroka, asi kuburikidza yakananga engineering dialogue: GD&T dudziro, manufacturability mhinduro mukati meawa makumi mana nemasere, uye vhiki nevhiki kugadzirwa kwezvigadziriso zvine humbowo hwemifananidzo hwezviitiko zvakakosha.
Ramangwana rekukandira jecha chairo riri mumahybrid workflows-apo kukanda kunotsanangura kuwanda kwejometry uye kutendeseka, uye machining anoburitsa nzvimbo dzinoshanda uye dzakasimba dzinokwana. Izvo zvinoda kudzika kwemetallurgical njere, kusimba kwekubatanidza maitiro, uye zero kushivirira kwekufungidzira. Kana purojekiti yako inotevera ichida zvikamu zvinoita-kwete kungokwana-tanga nekujekesa kwemaitiro, kwete kungotora mutengo.
