摘要
提出了高速伺服直驱式旋锻机结构,分析设计了基于摆线运动曲线的锤头轮廓曲线,采用上限法确定了旋锻机在极限工况下的最大输出载荷上限的变化规律。研究表明,随着进料角的增大,锻机负载有所降低,但同时工件需要更大的推进力,因此实际中采用的进料角的范围为5°-15°。
In this paper, the servo motor driven swaging machine was designed; profile of striker was derived from cycloidal motion curve and its motion features were analyzed. The maximum load of swaging machine was calculated by upper bound method. According to the calculation, the maximum load of swaging machine decreased with die angle increasing, but on the other hand, the push force on perform increased. The compromised die angle in the field was 5°- 15°.
