摘要:

 利用装配有集磁器的平板电磁成形系统, 研究了金属板料小区域的电磁成形过程以及集磁器对板料电磁力的分布影响规律。结果表明: 通过集磁器的磁场聚集作用, 板料能够完成小区域的变形, 且成形效果较好, 能够贴紧凸模; 板料的变形主要分为3 个阶段, 首先是板料中心区域受到电磁力而发生微小变形, 随着电磁力的增大以及板料获得一定成形速度后, 中心区域快速完成变形, 最后是受力区域向板料外端移动, 在惯性共同作用下发生整体的下移, 完成变形。集磁器能够将板料受力区域集中在中心半径约15 mm 的区域内, 板料的成形高度为4 mm。

 The electromagnetic forming process of sheet metal in small area and the influence law of magnetic collector on the distribution of electromagnetic force for sheet metal were studied by using the plate electromagnetic forming system with magnetic collector. The results show that the sheet metal can complete the deformation of small area through the magnetic field aggregation of magnetic collector, the forming effect is good, and the sheet metal can cling to the punch. The deformation of sheet metal is mainly divided into three stages. First, the central area of sheet metal undergoes minor deformation due to electromagnetic force. Then, with the increasing of electromagnetic force and a certain forming speed obtained by the sheet metal, the central area rapidly completes deformation. Finally, the force-bearing area moves to the outer end of sheet metal, and under the joint action of inertia, the overall downward movement occurs to complete the deformation. The magnetic collector can concentrate the force-bearing area of sheet metal in an area with a central radius of about 15 mm, and the forming height of sheet metal is 4 mm.
