PURPOSE:To improve working efficiency and to reduce the cost of a die by providing 1st and 2nd cam slides moving by approaching to the die block fixed on a die shoe and preforming the machining of the different faces of a work by the punch arranged respectively. CONSTITUTION:A die block 12 and cam driver 13 are set up at the position apart in the specified distance by fixing on a die shoe 11. The 1st cam slide 14 is provided between the cam driver 13 and die block 12 and the 2nd cam slide 17 is arranged as well freely slidably in the horizontal direction on a punch shoe 16. With the descent of the punch shoe 16, the cam slide 17 is abutted to the cam slide 14 simultaneously with a pad 23 being brought into contact with the surface of a work 1 and the respective piercing punch 22, 21 works piercing simultaneously on the faces 1a, 1b of the work 1. The working efficiency is thus improved and the necessary number of dies is reduced, hence the die cost is reduced.
