    摘要： An ironing mold according to the present invention is provided with a punch, and a die which forms a pushing hole with respect to the punch. When the skewness Rsk of a surface treated metal plate is less than -0.6 and no less than -1.3, then the curvature radius of a shoulder portion of the die and a clearance between a radius end and the punch are determined such that Y, which is expressed by {(t re - C re )/t re } × 100, and X, which is expressed by r/t re , satisfy 0

    摘要： A formed material is manufactured by performing forming including at least one drawing-out process and at least one drawing process performed after the drawing-out process. A punch 31 used in the drawing-out process is formed to be wider on a rear end side than on a tip end side. By pushing a raw material metal plate into a pushing hole 30a together with the punch 31, ironing is performed on a region of the raw material metal plate corresponding to a flange portion.

    摘要： The invention provides a formed material manufacturing method by which unnecessary thickening of a flange can be avoided, a formed material can be reduced in weight, a base metal sheet can be reduced in size, uniformity of flange thickness can be improved, and a highly accurate flatness can be obtained, and the invention also to provide a formed material. The formed material manufacturing method allows a formed material to be manufactured by forming processes that include at least one drawing-out process, at least one drawing process performed after the drawing-out process, and at least one coining process performed after the drawing process. The width of the rear end side of a punch 31 used in the drawing-out process is set to be wider than the width of the tip end side thereof. An ironing process is performed on a region corresponding to the flange of the base metal sheet by pushing the base metal sheet together with the punch 31 into a pushing hole 30a.

    摘要： An ironing mold according to the present invention includes a punch that is inserted into a formed portion, and a die having a pushing hole into which the formed portion is pushed together with the punch. An inner peripheral surface extends non-parallel to an outer peripheral surface of the punch, and the inner peripheral surface is provided with a clearance that corresponds to an uneven plate thickness distribution, in the pushing direction, of the formed portion prior to the ironing relative to the outer peripheral surface to ensure that an amount of ironing applied to the formed portion remains constant in the pushing direction.
