Abstract

PURPOSE:To enable forming by one drawing without generating swells or creases in press drawing a product of U-shaped sectional form having a flat part and a recessed part on the bottom by using die cushions of a specified shape. CONSTITUTION:When manufacturing a product 1 of U-shaped sectional form having a flat part 22 and a reversely warped recessed part 5 on the bottom 4 by drawing a metallic plate using a press, the die cushion of the press is divided into the second cushion 21 for the flat part and the first cushion for the reversely warped recessed part. A raw material metallic plate 8 is held by blank holders 23, 24 and an upper die punch 27 is lowered until upper faces of die cushions 20, 21 become a continuous face to form a flat part 22 by the second die cushion 21 and the upper die punch 27. At the same time, both side walls 10 are formed. Then, the recessed part 5 is drawn and formed by the first die cushion 20 and the upper die punch 27.
