Abstract

PURPOSE:To form a metallic plate to U-shape responding to the external form of a mandrel faithfully by laying a flexible plate horizontally between props supported by tension springs and making it a receiver for a mandrel. CONSTITUTION:A metallic plate 13 is placed on the upper face of a flexible plate 10 of a mandrel receiver 6. The mandrel receiver 6 is moved upward and the flexible plate 10 is deformed along the outside of the mandrel 5. At the same time, the metallic plate 13 is pressed between the flexible plate and mandrel 5, and the metallic plate 13 is bent faithfully along the outside of the mandrel to U-shape to obtain desired U-shaped metallic plate 13. After that, the U-shaped metallic plate 13 is further bent along the mandrel 5. The end part is seamed and an elliptical external frame of a muffler is formed. When the mandrel 5 is lowered after removing formed metallic plate 13 from the mandrel 5, the flexible plate 10 restores its original horizontal position by the action of tension coil springs 12.
