n.奥氏体形变(奥氏体轧制成形法)
The feasibility of the ausforming used in producing coal cutter was reasoned. 论证了形变热处理工艺运用于截齿生产实际的可行性。
During ausform finishing process of hardened gears, there is plastic displacement of metal on the tooth surface and the distortion of tooth profile . 在齿轮热滚挤加工中,轮齿上的金属在强制挤压力的作用下沿齿面产生塑性流动,使齿形发生变化。
In this thesis, a new advanced technology, called ausform finishing, is first presented in our country for manufacturing hardened gears. 本文创新提出了用于硬齿面精加工的精密热滚挤技术。
A new kind of air-cooling bainitic steel's ausforming under three different temperature is developed and its impact capability and microstructure is discussed. 对一种新型空冷贝氏体钢的热形变工艺进行了研究,分析了此钢经三种温度热形变并以不同冷速处理后的显微组织及冲击性能。
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，对热滚挤加工设备样机进行了设计，并提出了加工误差的消减措施。
