    摘要:

    针对目前棒料高速柔性交接装置工作可靠性不高,上下游机节距不能根据需要调整,从而限制了下游机速度提高等问题,提出了一种棒料变节距柔性交接装置的工作原理,对棒料交接过程及运动干涉情况进行了分析.为提高棒料柔性交接的可靠性,对装置结构参数进行了多目标优化,改善了棒料轴向制动过程,减小了交接相对速度差和凸轮最大压力角,并通过仿真分析验证了优化设计的合理性.该装置交接定位准确、稳定,轴向制动平缓,变节距技术和装置为设计速度更高的下游机创造了有利条件,具有较高的实用价值.

    Abstract:

    To deal with the existing problems such as lower flexible work reliability, speed limit in downstream machine caused by invariable pitch in the transferring device of high-speed bar stock, the working principle of a flexible transferring device with variable pitch was proposed, and the transferring process and the motion interference of the bar stock were analyzed. In order to improve the flexible transferring reliability of the bar stock, the multi-objective optimization of device's structure was presented. The results have shown that the axial braking process of the bar stock is improved, the transferring speed difference and the maximum pressure angle of the cam are reduced, and the rationality of optimization design is verified through simulation. The device has the advantage of accurate location, steady transferring, gentle axial braking process, and variable pitch, which is beneficial to the enhancement of production ability in downstream machine.
