本文是为沈阳重机厂生产的摆式飞剪提高性能而作的理论分析工作。文中不仅考虑了飞剪机构的运动性能,而且还考虑了机构的动力性能及飞剪的抛钢要求,选择出较好的机构参数;通过对改进前后的机构性能进行分析比较,表明提高了原机构的性能。对国产摆式飞剪。目前围绕选择合理参数、提高剪切速度、改善飞剪性能,已开始了若干研究工作。但由于其摆架和下刀架质量很大,并且以较高的速度作非匀速运动,因此,在参数选择时,仅仅考虑机构的运动要求是不够的,还必须考虑机构的动力要求。本文运用复数向量法,动静法和一维搜索方法对该剪机构参数进行了改进。
This article is for the heavy machinery factory in Shenyang slewing shear to improve the performance of theoretical analysis. The paper not only considers the moving performance of the flying shear mechanism, but also takes into account the dynamic performance of the mechanism and the requirements of the cast-cutting of the flying shear, and chooses the better mechanical parameters. By analyzing and comparing the mechanical performance before and after the improvement, Institutional performance. On the domestic tilting flying shear. At present, a number of studies have been started around the selection of reasonable parameters, the improvement of shear rate and the improvement of flying shear performance. However, due to the high quality of the pendulum and lower tool holder and the non-uniform motion at high speed, it is not enough to consider only the movement requirements of the mechanism in parameter selection. The dynamic requirements of the mechanism must also be considered. In this paper, the complex vector method, static and dynamic methods and one-dimensional search method of the shear mechanism parameters are improved.
