圆锥形单点增量成形件轴向精度研究
Research on axial accuracy of cone type single point incremental forming parts
摘要
Abstract
Accuracy deficiency of the sheet metal single point incremental forming (SPIF) is an important factor restricting the development of this technology, with axial accuracy being the key part of the accuracy of workpieces.Firstly, the cause of axial error in the process of SPIF is analyzed based on 1060Aluminum sheet conical parts.Then, the finite element model is established, with the variation of the axial error under different process parameters discussed by numerical simulation.The selected process parameters include forming angle, layer spacing, sheet thickness, feed rate and diameter of tool head.Subsequently, the results of the numerical simulation are verified according to the corresponding experiments.Finally, the methods for improving the axial accuracy are presented.The results show that the axial error increases with the increase of tool head diameter, layer spacing, feed rate, forming angle and sheet thickness;the method for using height compensation and improving the tool rotation speed can effectively reduce the axial error and improve the accuracy of the parts.关键词
