摘要/Abstract

摘要： 为实现锥形孔电磁翻边的线圈设计和成形工艺，基于LS-DYNA有限元仿真软件建立了有限元模型，设计了变匝间距随形线圈，得到了最佳放电电压；揭示了线圈设计和放电电压对成形结果的影响；随后进行工艺试验，得到了满足技术要求的零件。结果表明：采用变匝间距设计的线圈可以增大小圆弧区的电磁力密度，进而使小圆弧区成形高度明显增大，成形均匀性改善；随着电压增大，零件受到的电磁力增大，小圆弧区贴模间隙迅速减小，大圆弧区贴模间隙几乎不变，直边区贴模间隙减小后反弹；最佳放电电压为14 kV，得到零件最大贴模间隙为0.61 mm，减薄率为18%，满足技术要求。

Abstract: The coil design and forming processes of electromagnetic flanging of conical holes were achieved by establishing a finite element model using LS-DYNA finite element simulation software. A coil with variable turn spacing was designed, and the optimal discharge voltage was determined to investigate their influence on formability. Subsequently, a processing test was conducted to obtain parts meeting technical requirements. The results demonstrate that utilizing a coil with variable turn spacing design increases the electromagnetic force density in the small circle area, significantly enhances the forming height in this region, and improves overall forming uniformity. As voltage increases, there is an accompanying increase in electromagnetic force; consequently, there is rapid reduction in die gap within the small arc regions while remaining almost unchanged within large arc regions. Additionally, die gap within straight side regions rebounds after initial decrease. The optimum discharge voltage of 14 kV results in a maximum die gap of 0.61 mm and thinning rate of 18%, so that technical requirements are met.
