Study on the Influencing Factors and Forming Process Selection of Sheet Metal Bending Spring Back Defects

Abstract In recent years, with navigation, aviation, chemical manufacturing, and automobile bodies increasing requirements for lightweight, high efficiency, energy saving, quality in the selection of materials manufacturing process are also improved. However, there is an unavoidable elastic deformation plastic bending panel veneer, accuracy workpiece impacted by spring back phenomenon, which causes dimensional shape inaccuracies veneer. The purpose this paper to summarize analyze phenomenon flexural caused material processing techniques discuss solution flexion bounce problem from selection, method, machining mold, can be applied avoid wastage.
