Abstract
PURPOSE: To manufacture the cylindrical sponge metal with strong mechanical strength in dimensional accuracy, by forming the sponge metal sheet into a cylinder possessing the overlapping part, and next, by inserting the mandrel in diameter equal to the purposed inner diameter, and by impressing the impact on this cylindrical sponge metal sheet from the diagonal opposite directions.
CONSTITUTION: The sponge metal sheet possessing the three-dimensional irregular network is formed into the cylinder possessing the overlapping part 1 by the three- high roll; the mandrel 6 in diameter equal to the purposed inner diameter is inserted into this cylindrical sheet 2. Then, an impact is impressed on the outer surface of the sponge metal sheet 2 internally holding the mandrel 6 by a couple of dies 4 from the diagonal opposite directions simultaneously; further, another impact is impressed by another couple of dies 5. If respective couple of dies 4, 5, repeats alternately these impact motions, the sponge metal is transferred toward the mandrel 6, and the sponge metal sheet 2 is finished into the cylinder in which both edges of the overlapping part 1 are bonded by interlocking each other.
