摘　　要：为了实现先将钢筋放入网片后再折弯这一工艺,设计一种新型钢筋折弯机构。简化机构,建立数学模型,并使用ADAMS对机构运动学与动力学进行仿真分析,验证机构的合理性,为下一步的有限元分析提供初始数据。使用ANSYS对机构的危险运动状态进行有限元分析,验证机构的可靠性。加工制造出实物样机并进行弯折试验。该机构不仅可以满足这种特殊工艺的要求,而且可作为六轴机器人的执行机构,让钢筋折弯工序更加智能化。In order to realize the process of bending after placing the reinforcement into the mesh, a new kind of reinforcement bending mechanism was designed. After simplifying the mechanism, the mathematical model was established, and the kinematics and dynamics of the mechanism were analyzed and simulated with ADAMS to verify the rationality of the mechanism and provide initial data for the next finite element analysis. ANSYS was used to analyze the dangerous motion state of the mechanism to verify the reliability of the mechanism. Finally, the physical prototype was manufactured and bending test was performed. The mechanism can not only meet the requirements of this special process, but also be used as the actuator of six axis robot to make the process of steel bar bending more intelligent.
