摘　　要：随着工业技术的不断发展,对于板料成形过程中压边圈的压边力控制要求越来越高。压边力的大小和位置直接影响板料的变形程度和成形质量,因此对其进行精准控制具有重要意义。过去的研究主要集中在拉延成形工艺的优化和模拟仿真技术的应用,而对于压边力对板料变形极限的影响研究相对较少。因此,有必要对压边力的影响进行系统的研究和分析,以便更好地理解其作用机制,为相关工业领域提供可靠的生产工艺和技术支持。With the continuous development of industrial technology,the requirements for controlling the edge holding force of the blank ring in the sheet metal forming process are becoming higher and higher.The magnitude and position of the edge holding force directly affect the deformation degree and forming quality of the sheet metal,so precise control of it is of great significance.Previous research has mainly focused on the optimization of the drawing forming process and the application of simulation technology,while there is relatively little research on the impact of edge holding force on the deformation limit of the sheet metal.Therefore,it is necessary to systematically study and analyze the influence of edge holding force in order to better understand its mechanism and provide reliable production processes and technical support for related industrial fields.
