| 摘 要： | 为了准确地预测数控滚弯成形金属线材中的回弹量,从而给出加工补偿值,采用DEFORM软件进行了45号钢线材滚弯过程的有限元仿真,得出滚轮转过的角度与线材最终成形的角度在一定范围内呈线性关系.通过数控弯丝机滚弯线材的试验验证了此关系在一定条件下是准确的,最后综合模拟和试验数据导出经验公式用于加工补偿.

| Abstract: | In order to predict the springback angle of metallic wire the CNC rolled accurately and give processing compensation.we use DEFORM to carry out the finite element simulation of the process of the wire rolled and reach a conclusion that the angle that the wheel turns keeps a linear relationship with the final forming angle of wire within a certain range.And it has been proved to be truth under certain conditions by the roll bending CNC machines,than we derive the experiential formulae used to machining compensation with the data of simulations and experiment. |
