n.奧氏體形變(奧氏體軋制成形法)

The feasibility of the ausforming used in producing coal cutter was reasoned. 論證了形變熱處理工藝運用于截齒生產(chǎn)實際的可行性。

During ausform finishing process of hardened gears, there is plastic displacement of metal on the tooth surface and the distortion of tooth profile . 在齒輪熱滾擠加工中,輪齒上的金屬在強制擠壓力的作用下沿齒面產(chǎn)生塑性流動,使齒形發(fā)生變化。

In this thesis, a new advanced technology, called ausform finishing, is first presented in our country for manufacturing hardened gears. 本文創(chuàng)新提出了用于硬齒面精加工的精密熱滾擠技術(shù)。

A new kind of air-cooling bainitic steel's ausforming under three different temperature is developed and its impact capability and microstructure is discussed. 對一種新型空冷貝氏體鋼的熱形變工藝進行了研究,分析了此鋼經(jīng)三種溫度熱形變并以不同冷速處理后的顯微組織及沖擊性能。

At last, the design of the prototype machine for ausform finishing process is carried out, and compensating measures of machining error are put forward. 最后，對熱滾擠加工設(shè)備樣機進行了設(shè)計，并提出了加工誤差的消減措施。
