description	The present invention relates to a method and an apparatus for bending a workpiece, and more particularly to a method and an apparatus for bending a nonferrous metal workpiece to be mounted on a chassis. The present invention is characterized in that a workpiece is prepared by extruding nonferrous metal through a die with uniform shape and plastic working the extruded nonferrous metal, the workpiece fixed at the mandrel operating plates (31, 31') by the movement of a stopper by the piston (41) disposed on a workpiece fixing apparatus, and the workpiece simultaneously bent at its both sides to perform stretching and mandrel operation by an M/C (machine control unit). Thereby, the wrinkle problem can be solved. La présente invention porte sur un procédé et un appareil de pliage d'une pièce, et notamment sur un procédé et un appareil de pliage d'une pièce de métal non ferreux devant être montée sur un châssis. Le procédé consiste à préparer la pièce en extrudant un métal non ferreux dans une matrice uniforme et par façonnage à l'état plastique du métal non ferreux extrudé. La pièce est fixée au niveau des plaques de serrage en mandrins (31, 31') par le déplacement d'une butée commandée par le piston (41) placé sur un appareil de fixation de pièces, puis la pièce est pliée simultanément sur ses deux côtés pour effectuer l'opération d'étirage et de pliage au moyen d'une machine-outil, ce qui évite la formation de rides.
