A new type of high-efficient bar of finishing equipment, especially bar straightening machine, is to ensure that the quality of the bar key. If great material bending, be about to use material to work out a big stick a small parts, material utilization rate is not high, the poor economy. Therefore, in processing parts need before will bar stock straightening. For this design a short bar stock straightening machine. To further perfect finishing process and improve rolling speed, must make the new high efficiency bar straightening machine. This paper used the planet type rub roll straightening method came straight bar. The move for roller 1 hemilateral pan, a continuous rotary movement; Static hemilateral pan for arc component 3, on the open of the slot also by the deep becomes shallow and finally disappeared. This scheme can not only will bar stock school very straight, and automation degree and high productivity, and use this principle to further perfect finishing process and improve rolling speed. 【Keywords】Bar stock Straightening institutions Straightening machine 目录 1 、系统总体方案设计工作原理 4 2、 总体方案设计 6 2.1执行机构运动方案的拟定 6 2.1.1滚子弧形搓板弹簧 6 2.1.2传动系统运动方案的拟定 6 3、机构设计计算 8 3.1执行机构设计 8 3.1.1滚子设计 8 3.1.2滑块设计 8 3.1.3摆杆设计 9 4、传动系统设计 10 4.1电动机择选 10 4.1.1 选择电动机的类型和结构 10 4.1.2确定电动机功率和型号 10 4.2 传动装置运动及动力参数计算 11 4.2.1各传动比的计算 11 4.2.2 V带传动的设计与计算 12 4.3摆杆设计 13 4.3.1摆杆设计 13 4.4轴的设计 14 4.4.1滚子轴设计： 14 4.4.2凸轮轴设计： 19 4.4.3压板轴设计： 22 4.5 键的设计与校核 23 4.5.1凸轮轴上键的设计与校核 23 4.5.2其他轴上键的设计与校核 24 4.6滚动轴承的校核 24 4.6.1计算滚子轴的轴承： 24 4.6.2计算凸轮轴的轴承： 25 4.6.3 其他轴承 25 4.7压板的设计校核 25 4.8弹簧的校核 27 4.8.1摆杆处拉伸弹簧 27 4.8.2压板处压缩弹簧 28 参考文献 29 谢词 30 1 、系统总体方案设计工作原理 校直机的工作原理：辊子
