<p>PROBLEM TO BE SOLVED: To make a measurement accuracy high and reduce a production cost and manhours through reduction of a formworking cost, forming manchours, prevention of partial thickness reduction or of a creation of scratches, and a improvement of measurement accuracy of the finish and the like. SOLUTION: A workpiece 12 mounted on a die 11 is held by a wrinkles presser bar flat 13 with a given load. The die 11 is rotated at a given speed, and, a presser bar 17, which couple-rotates, touches the workpiece 12 at an angle. The presser bar 17 is held on a moving stand movable along an arbitrary prosecution shape against the workpiece 12 and, is moved along the product shape while the workpiece 2 is rotated by the rotation of the die 11. The plate material is formed by pulling the workpiece 12 into the die 11. Thus a mold which corresponds to a product becomes unnecessary and even if the shape is difficult to form, the forming is made possible without creating wrinkles and the like by setting a route of the presser bar 17 arbitrarily. Further, the processing power is reduced.</p> |
