摘　　要：变截面波纹板应用广泛,但目前仍采用传统的冲压成形工艺生产。为提高生产效率,本研究结合冷弯成形技术效率高、成形质量好、精度高等优点,以变截面波纹板的冷弯成形过程为研究对象,确定了孔型系统、坯料宽度、成形道次、弯曲角、牌坊间距和辊径差等具体成形参数,并得出辊花图和轧辊模型,为变截面波纹板冷弯成形过程的有限元模拟和大规模工业化生产提供理论依据。Variable cross-section corrugated plates are widely used,but they are still produced by the traditional press molding process.In order to improve production efficiency,this study combines the advantages of cold forming technology with high efficiency,good forming quality and high precision,and takes the cold forming process of variable cross-section corrugated sheet as the object of study,determines the specific forming parameters such as the hole system,billet width,number of forming passes,bending angle,plaque spacing and roll diameter difference and draws the roll flower diagrams and roll models,and provides theoretical bases for the finite element simulation of the cold forming process of the variable cross-section corrugated sheet and large-scale industrialized production.Provide theoretical basis for the finite element simulation of variable section corrugated plate cold forming process and large-scale industrialized production.
