Kana mainjiniya achinge ataura simbi isina tsvina inokanda zvikamu zvemotokari, havasi kungosarudza chinhu-vari kuzvipira kugadzikana pasi pemhepo inopisa bhasikoro, kuramba kwecorrosion mumvura ine hukasha, uye kusarongeka kwemaitiro pa300+ bar inoshanda zvinomanikidza. Ndicho chikonzero kutsvaga kubva kune a simbi isina tsvina ichikanda auto zvikamu fekitori neyakasimbiswa metallurgical discipline-kwete chete foundry capacity-inopa musiyano pakati pekutadza kwemumunda ne15-year service life.
Nei "Kukanda" Kwega Kusina Kukwana-Kunyanya kuMotokari-Giredhi Precision
Isu takaona mapurojekiti akawanda achimira kana kukanda kuchipfuura ongororo yekuona asi kutadza kumanikidza kuyedzwa pagungano rekupedzisira. Chikonzero chikuru? Chimiro chezviyo chisingawirirani kubva pakusimba kusingadzoreki, kana kusara kunetseka kwakasara kusati kwagadziriswa pamberi pekugadzira. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., simbi yese isina tsvina inotanga neAMS 5387-inoenderana nembishi stock-inoteedzerwa kune inopisa nhamba, inopupurirwa simba rekusimba ≥860 MPa uye elongation ≥12% mune as-cast + mhinduro-yakagadziriswa mamiriro. Hapana batch inotsiva. Hapana nzira dzekudimbudzira. Isu tinobvumira kunyunguduka chemistry nevatinodyidzana navo zvinhu tisati tadira.
Yedu yekukanda jecha maitiro anoshandisa ceramic-yakavharwa molds yekupedzisa pamusoro Ra ≤6.3 μm-yakasimba zvakakwana kuti isvetuke machining ane hutsinye pazviso zvisiri-akakosha. Kune akaomesesa geometries senge piston pombi silinda dzimba, isu tinosanganisa mari yekukandira kune dzakatetepa-madziro zvikamu (madziro ukobvu pasi kusvika 4.5 mm) nekunyatso kutendeuka kweCNC uye kukuya kwemukati-zvese mukati meimwe nzvimbo. Iko kusanganisa kwakatwasuka kunobvisa pakati-nzvimbo dimensional kukukurwa. Mutengi muGermany nguva pfupi yadarika akashuma 99.8% yekutanga-pass goho pane gumi nemaviri-chikamu hydraulic manifold assembly-nekuti flange face flatness (0.015 mm max deviation) uye port thread concentricity (0.02 mm TIR) yakaitwa pamatanho ese ekukanda uye ekupedzisa.
Uko Mafekitari Akawanda Anocheka Makona—Uye Nzira Yatinoadzivisa
Vamwe vanogadzira vanobata simbi isina tsvina sechinhu chekutengesa. Vanodurura, vanozunza kunze, muchina, uye nengarava. Asi high-performance auto components inoda zvimwe: controlled cooling rates kudzivirira sigma phase formation mu316SS; kudzvinyirira-kuzorodza annealing * pamberi * yekupedzisira machining kukiya mu geometry; uye CMM-yakavakirwa GD&T kusimbiswa pane yese mijenya-kwete chete yekutanga-chinyorwa samples.
Isu tinomhanyisa matatu anosungirwa kutarisa nzvimbo:
- Inouya yekusimbisa zvinhu kuburikidza neOES spectrometry uye tensile bar kuyedzwa
- In-process yekuongorora mushure mekuita kwakashata machining uchishandisa Zeiss CONTURA G2 CMMs-ine yakazara ASME Y14.5-inoenderana mishumo yechinzvimbo, chimiro, uye kubuda.
- Yekupedzisira inoshanda bvunzo: hydrostatic kumanikidza kubata pa 1.5 × yakayerwa kushanda kumanikidza kwemaminetsi makumi matatu, pamwe nedhayi-inopinda nekuongorora paASTM E165.
Uku hakusi kuwandisa-ndiwo mabatiro atinoita kuti winch centre shaft roller yemota iri off-highway inopona 20,000 cycles of 12-ton dynamic loading pasina microcrack kutanga.
Kuita Kwechokwadi Kwenyika Inoda Kuumba Mano Edu
Simbi yedu isina tsvina yekukanda auto zvikamu zvinoshandira nharaunda uko kutadza kunoreva kuderera kunodhura $18,000/awa. Saka isu tinoinjiniya yeyakaipisisa-mamiriro ezvinhu-kwete iyo database avhareji. Somuenzaniso:
- Mavharuvhu ekudzvanya kwepamusoro-soro akajairika-njanji madhiziri masisitimu anomhanyisa kupisa bhasikoro kubva -40 ° C kusvika + 180 ° C - yakasimbiswa ne500 mitsetse isati yasununguka.
- Nheyo dzepombi dzezvikamu zvekubvisa mvura yegungwa dzinoyedzwa kuti pitting kuramba paASTM G48 Method A (6% FeCl₃, maawa makumi maviri nemana, hapana makomba> 0.05 mm kudzika)
- Ese T800 cobalt-based alloy castings anosanganisira microstructure ongororo kuburikidza neSEM/EDS kusimbisa yunifomu carbide dispersion-yakakosha kune abrasive kupfeka kuramba mune slurry pombi impellers.
Isu hatingosangana neISO 9001. Isu tinoenzanisa nhanho yega yega neSAE AS9100 nheyo-kunyangwe isu tisina aerospace-certified-nekuti kuomarara kunotamisa zvakananga kukuvimbika kwemotokari.
Kusarudza Waunoshanda Naye Kunoreva Kubvunza Mibvunzo Yakakodzera
Kana uri kuongorora a simbi isina tsvina ichikanda auto zvikamu fekitori, bvunza zvinhu zvitatu izvi usati wasaina PO:
- Unogona here kupa kuzere kwezvinhu kuteedzera-kubva kunhamba yekupisa kusvika kune yekupedzisira bvunzo report-yekutumirwa kwemwedzi wapfuura?
- Iwe unoita kushushikana-kuzorodza annealing * pamberi * yekupedzisira machining? Kana zvisina kudaro, unotsiva sei kukanganisa?
- Ndeipi chikamu chako chekugadzira chakareba-richimhanya? Ndiratidze iyo Cpk data yezviyero zvakakosha mukati memwedzi mitanhatu.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoburitsa iyi data ichiita panguva yekuongorora kweinjiniya. Isu tinoziva kuti kuvimba hakuna kuvakirwa pamabhurocha - kunowanikwa kuburikidza nekujeka pane zvakayerwa, kuti zvinoyerwa sei, uye chii chinoitika kana chiyero chikawira kunze kwemiganhu. Nguva yedu yekutungamira yepakati-vhoriyamu maodha (50-500 pcs) mavhiki gumi nemana-kwete nekuti isu tinononoka, asi nekuti isu tinovaka mubuffer yekusimbisa metallurgical, kwete kungoronga muchina.
Stainless simbi inokandira auto zvikamu hazvichinjike. Ndivo vanogonesa system. Uye kugonesa kuita kunotanga kare mold isati yadururwa - nesainzi yezvinhu, maitiro ekuranga, uye zero kushivirira kwekufungidzira. Ndiwo chiyero chatinobata-kwete chete kune vatengi vedu zvakatemwa, asi kumichina zvikamu zvadzo zvichave nesimba mangwana.
