Analysis of Plate Forming Process Based on Dynaform

Abstract

By analyzing the structural characteristics of the product, it is determined that the main body of the plate needs to be processed by drawing, and the features around the plate have a large flanging angle, which requires two flanging operations to complete. The final forming process for the plate is determined to be:deep drawing,blanking, single flanging, and secondary flanging. According to the forming principle, 3D software is used to model the analysis models of each, and the mold structure is preliminarily determined. The Dynaform software is used to analyze the plate forming process, to check the FLD diagram and material thickness distribution diagram, and to analyze the possible locations of cracks and wrinkles during the forming process. The causes of defects at different locations are analyzed, and by the analysis model multiple times and adjusting the forming process parameters, reasonable forming parameters and mold structures are obtained, which effectively reduce the risk of cracks and wrinkles during the process, providing a reference for mold design and prevention of production defects.
