Semi yakasimba simbi yekukandira fekitori mhinduro inovhara mukaha pakati pechinyakare kufa kukandira uye kugadzira-kuunza pedyo-net-shape zvikamu zvine epamusoro mechanicha zvinhu, yakaderedzwa porosity, uye yakasimba dimensional kudzora. Asi hazvisi zvese zvinowanikwa zvinogona kugadzira zvakavimbika zvikamu zve hydraulic valves, high-pressure pump housings, kana cobalt-alloy nozzles inopona 200+ bar cycling uye abrasive fluid media. Isu takaona mapurojekiti akawandisa achimira padanho reiyo prototype-kwete nekuda kwekukanganisa dhizaini, asi nekuti iyo semi yakasimba simbi yekukanda fekitori yakashaya chirango chemetallurgical, in-process verification, kana hybrid process yekubatanidza.
Nei Semi-Solid Casting Inotadza-Uye Chii Chinoshanda Chaizvo
Kukundikana kwakawanda kunotsvaga kune zvitatu midzi zvikonzero: kusaenderana slurry tembiricha kudzora panguva rheocasting, kusakwana kunatswa zviyo mu semi-yakasimba slurry, kana misalignment pakati kukanda shrinkage muripo uye kudzika CNC machining mvumo. Panzvimbo yedu muQingdao, tinoyera slurry viscosity munguva chaiyo tichishandisa inline rotational rheometers-kwete chete setpoint thermocouples. Takaona kuti ± 1.5 ° C kutsauka pamusoro pe582 ° C muAMS 5387 cobalt alloy slurry inowedzera micro-shrinkage ne 23% muhumburumbira yeimba madziro akakora kupfuura 12 mm. Ndosaka isu takamisikidza yekudziya yekufungidzira zvakananga mupfuti sleeve uye kugadzirisa jekiseni velocity zvine simba pachikamu chejometri.
Zvinotonyanya kukosha, semi-solid casting haisi yega. Iyo node mucheni chaiyo yekugadzira. Imba yepiston pombi yakakandwa mu semi-solid T800 cobalt alloy inofanirwa kuchengetedza yakagadzikana microstructure kuburikidza nekushushikana-kubvisa kupisa kurapwa * pamberi pe * mashanu-axis milling yevharuvhu port contours. Kana imba yekukandira isingadzore kutonhora kwemazinga mukati me ± 3 ° C / min kubva 1050 ° C kusvika 600 ° C-kana kana ivo vasina CMM-yakabatana GD & T kusimbiswa pane yakasvibira-nyika castings-chikamu chekupedzisira chichatadza kushanda kwekumanikidza kuyedzwa. Tinoita zvose. Batch rega rega rinosanganisira spectrographic analysis, dendrite arm spacing (DAS) kuyerwa pasi peSEM, uye yakazara kupisa-yekurapa logi traceability.
Zvina Zvisina Kukurukurirana Zvikwanisiro zveMission-Critical Applications
Yechokwadi semi yakasimba simbi yekukanda fekitori inofanirwa kuendesa kupfuura simbi yakaumbwa. Inofanira kuvimbisa kushanda pasi pezvakatemwa. Hezvino izvo zvatinosimbisa tisati tatora chero basa:
- Material pedigree control: Yakasvibira cobalt-nickel ingots inocheneswa chete kubva kumagiyo akasimbiswa kune ASTM B575 uye AMS 5737-ine mill test mishumo yakachinjika-yakatariswa pamusoro peinouya spectrography.
- Process-yakabatanidzwa metrology: In-line laser scanning ye mold cavity pre-fill, post-ejection CMM kuongororwa kweakakosha datum nzvimbo, uye optical contour mepu yemukati inoyerera ndima isati yagadzirwa.
- Hybrid kushivirira stacking: Isu tinoverengera yakawedzera kukanganisa mabhajeti pane yekukanda shrinkage, kupisa-kubata kukanganisa, uye akawanda-axis toolpath deflection-kwete kungoshandisa generic ± 0.3 mm mvumo
- Inoshanda yekusimbisa protocol: Yese yevhavhavhavha yekumanikidza imba inopinda helium kuvuza kuyedzwa pa1.5 × kushanda kumanikidza, ipapo munyu-spray kuratidzwa paASTM B117 kwemaawa 96 isati yapedzwa yekupedzisira.
Real-World Tradeoffs Iwe Unofanirwa Kubvuma
Mamwe mainjiniya anofungidzira semi-yakasimba kukanda otomatiki inocheka mitengo. Izvo hazvidaro-kunze kwekunge uchinge wakanangana nechikamu chemhuri. Kune dzakatetepa-madziro, dzakakwirira-zvakaoma geometries senge winch centre shaft rollers ane akabatanidzwa spline mazino uye oiri grooves, semi-solid inoderedza machining nguva ne40% uye inovandudza kuneta hupenyu ne2.7 × kupesana nejecha-cast yakaenzana. Asi kune nyore flanges pasi pe50 mm gobvu? Zvakajairwa kuisa mari kukanda kazhinji zvinounza iri nani ROI.
Isu nguva pfupi yadarika takashanda neEuropean hydraulic OEM iyo yakasimbirira pane semi-yakasimba kune 320 mm dhayamita pombi hwaro. Kutevedzera kwavo kwakafanotaura 0.12 mm warpage. Chaiyo as-cast warpage yaive 0.28 mm-nekuti modhi yavo haina kuverengera kuchinja kwepakati panguva yejekiseni reslurry mu ceramic shell molds. Taimhanya nemiedzo yemuviri nemajeji akadzamirirwa, akagadzirisa kuomarara kwepini, uye nekuwedzera zvivharo zvechill. Yekupedzisira warpage yakadonha kusvika 0.14 mm. Chidzidzo chacho? Kutevedzera kunobatsira-asi chete kana kwakavakirwa mukuyerwa kwekupisa-mechanicha maitiro.
Chii chekuda kubva kune Yako Semi Solid Metal Casting Factory
Bvunza mibvunzo iyi usati wasaina NDA:
- Unogona kundiratidza matatu ekupedzisira AMS 5387 lot certification-kusanganisira DAS kukosha uye interdendritic segregation mepu?
- Iwe unoita-in-process ultrasonic tests pane castings yakakora kupfuura 25 mm-kana kungoongorora kwekupedzisira?
