Kev Ua Haujlwm Zoo
Nyob rau hauv tib txoj kab uas hla, thaum lub phab ntsa thickness ntawm lub hollow ncej ncav cuag 10 hli, nws dabtsi yog khoov zog seem modulus tuaj yeem ncav cuag 98% ntawm cov khoom ncej (W tus nqi 0.096cm³ vs 0.098cm³). Hais txog torsional txhav, nyob rau hauv tib cov khoom thiab ntoo khaub lig-sectional cheeb tsam tej yam kev mob, ib tug hollow ncej nce torsional efficiency los ntawm 17% -23% los ntawm kev nce qhov nruab nrab ntawm cov khoom mus rau qhov chaw ncej.
Piv nrog rau cov khoom siv, nws muaj:
- Qhov hnyav ntawm 30% -45% (rau tib txoj kab uas hla)
- Cov khoom siv txo qis ntawm 20% -30%
- Axial qhov chaw siv kev txhim kho ntawm 10%
Kev tsim khoom
Ib qho peb -theem txheej txheem ntawm roughing → semi-finishing → finishing yog saws. Ib tug txheej txheem txheej txheem yog raws li nram no:
1. Blanking: Txiav bar Tshuag rau φ60 × 220mm specifications
2. Rough Tig: Tawm ntawm 2 hli machining nyiaj pub rau ntawm txoj kab uas hla
3. Drilling: Machining ib tug φ28 los ntawm lub qhov (reaming yog yuav tsum tau tom qab drilling los txhim kho qhov tseeb)
4. Kev kho cua sov: quenching thiab tempering rau HRC28-32
5. Tig Tig: Tswj cov txheej txheem sab nraud ntawm qhov ntev ntawm IT6 qib
Cov txheej txheem tseem ceeb Parameter:
- Rough Tig ntawm φ46 Sab Nraud Sab Nraud: Spindle ceev 600r / min, pub tus nqi 0.3mm / r
- Tiav Tiav ntawm φ28 Inner Qhov: Siv cov cuab yeej CBN, nto roughness Ra tsawg dua lossis sib npaug rau 1.6μm
- Spline Machining: Siv lub siab broach, cumulative pitch yuam kev Tsawg dua los yog sib npaug rau 0.02mm
