Dab tsi yog qhov yuav tsum tau thaum ua precision casting qhov chaw?
Tus txheej txheem ntawm casting cov kua hlau mus rau hauv lub puab phab ntsa ntawm lub casting uas yog raws li nyob rau hauv cov tsos ntawm ib feem, thiab tos kom nws txias thiab solidified, thiaj li mus tau lub cam khwb cia ib feem los yog dawb paug yog hu ua casting. Ib qho khoom uas tau txais los ntawm casting yog hu ua casting piece. Yog li dab tsi yog cov kev cai dav dav ntawm casting qhov chaw?
Cov kev cai dav dav rau precision casting qhov chaw:
1. Cov kev xav tau ntawm cov khoom siv raw. Qhov tseem ceeb yog compressive zog, compressive zog, tensile zog, cuam tshuam toughness.
2. Precision ntawm specifications, qauv thiab cov duab tolerances. Cov khoom sib txawv ntawm qhov sib txawv muaj qhov sib txawv, thiab cov qauv sib txawv thiab cov qauv kev ua siab ntev geometric thiab cov rooj sib txawv ntawm qib siab tau siv.
3. Raws li daim ntawv thov yuav tsum tau ua, qhov kev lees paub ua tiav qhov project yuav tsum tau teev tseg rau lwm yam tsis xws luag ntawm casting qhov chaw. Xws li qhov chaw nres nkoj, xuab zeb qhov, casting defects, casting defects, vuam nodules, xuab zeb kav, tawg, thiab lwm yam.
Cov khoom siv hlau ua vaj tse yog nchuav rau hauv pwm kab noj hniav ntawm cov cuab yeej casting abraded nrog cov tsos thiab cov ntsiab lus ntawm qhov, thiab nws yog txias thiab solidified kom tau qhov khoob los yog ib feem hu ua qhov casting.
Qhov yuav tsum tau muaj rau formulation ntawm casting qhov chaw:
1. Ua tau raws li qhov xav tau ntawm compressive zog thiab dabtsi yog khoov nruj. Lub zog compressive ntawm precision castings yog ib qho teeb meem tseem ceeb heev rau lub plhaub qhov chaw uas muaj peev xwm loj. Tab sis rau feem coob ntawm cov plhaub, lub ntsiab tseem ceeb rau kev ntsuas cov yam ntxwv yog khoov nruj, vim hais tias cov bending txhav ntawm lub plhaub tsis tsuas yog ua phem rau lub hauv paus ua hauj lwm ntawm cov kis tau tus mob qhov chaw, tab sis kuj ua phem rau cov precision ua hauj lwm ntawm prefabricated Cheebtsam. Casting qhov chaw ceev thiab yooj yim tsis siv neeg tswj qauv specifications xaiv lub vev xaib suav nrog.
2. Thaum tshav kub kub dissipation yam ntxwv thiab thermal deformation teeb meem. Kev sib txhuam thiab cua sov ntawm qhov chaw hauv lub cev ntawm lub thawv yuav hloov lub viscosity ntawm cov roj lubricating thiab ua rau nws cov kev ua haujlwm lubrication. Qhov kub nce siab ua rau thermal deformation ntawm lub plhaub, tshwj xeeb tshaj yog cov thermal deformation thiab thermal stress yam tsis muaj kev sib koom ua ke ntawm ambient kub, uas muaj kev cuam tshuam zoo rau qhov precision thiab compressive lub zog ntawm lub plhaub.
3. Tsim nyog cov khoom tsim. Piv txwv li, kev faib tawm ntawm lub fulcrum, qhov tsim nyog layout ntawm qhov cuab lub zog, qhov qhib txoj hauj lwm thiab lub tswv yim tsim ntawm lub buckle qauv yuav tsum tau conducive rau kev txhim kho lub compressive zog thiab dabtsi yog khoov nruj ntawm lub plhaub.
4, kev ua haujlwm zoo. Xws li cov khoom siv khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob
Casting yog siv daim ntawv ntawm cov khoom siv casting khoom ua haujlwm, feem ntau yuav tsum tau ua tiav qee qhov kev ua haujlwm thiab kev tsim khoom. Yog li txhua leej txhua tus tau mastered tus qauv specification ntawm casting qhov chaw?
