回冲装置传动机构优化设计

针对连杆驱动的回冲装置无法满足多品种弹壳制造的问题，设计一种新型回冲装置传动机构。根据弹壳 回冲工艺要求，深入分析回冲滑块的运动机理，构建共轭凸轮驱动机构的数学模型，给出新型回冲装置的设计实例， 并对该新型装置的回冲滑块构件进行运动分析。分析结果表明：该装置能更好地满足回冲工艺要求，有效地降低回 冲力对弹壳底部的冲击作用，满足单机设备生产多型号弹壳的需求。

Optimal Design of Transmission Mechanism of Backflushing Device

In order to solve the problem that the connecting rod driven recoil device can not meet the requirements of manufacturing various cartridge cases, a new type of backflushing device transmission mechanism was designed. According to the technological requirements of cartridge case backflushing, the motion mechanism of the backflushing slider is analyzed in depth, the mathematical model of the conjugate cam driving mechanism is constructed, and a design example of a new backflushing device is given, and the motion analysis of the backflushing slider component of the new device is carried out. The analysis results show that the device can better meet the requirements of the backwash process, effectively reduce the impact of the backwash force on the bottom of the cartridge case, and meet the needs of single-machine equipment to produce multiple types of cartridge cases.
