扇形板的双弧形板材锻造

Segments Forged with Double-Curve Plate

介绍扇形板专用辅具锻造工艺的发展过程,指出锻造毛坯尺寸是设计专用辅具的关键参数,确定制坯和辅具弧形工艺是扇形板锻造成形的重要因素,重点介绍扇形板的锻造工艺的优化,通过改进生产工艺不仅节约原材料,而且提高工作效率及锻件的内部质量。

The paper presents the evolution of segment forging techniques with special tools and points out the dimensions of blanks are critical data to design special tools,and the establishment of blank making technique and curve making technique with special tools are important to form segments.The optimized segment forging technique is the focus of the paper and could not only save raw materials but also improve the productivity and internal quality of forgings.
