形される。When the elevating body 8 further descends, the press pad 9 presses the workpiece W.
The workpiece W is pressed between the support surface 16 and the pressing pad 9, and the workpiece W is positioned. Moreover, even though the elevating body 8 is lowered, the pressure pad 9 is prevented from descending, so that the third and fourth pressure receiving surfaces 29, 30 are pressed against the third and fourth pressure receiving surfaces 29 and 30 in response to the lowering of the elevating body 8. Surface 33,
34, the swing pad 10 and swing punch 11 start swinging toward the side plate 2, and first the swing pad 10 contacts the side plate 2, and the side plate 2 is moved between the die 6 and the swing pad 10. Being pinched. Next, the swing pad 11 cooperates with the drawing die portion 18 of the die 6 to draw the side plate 2, and the recess 3 is formed in the side plate 2.

。Thereafter, as the elevating body 8 further descends, the bend punch 7 cooperates with the bending die part 17 of the die 6 to perform the bending process, and the bent part 4 is formed at the lower end of the side plate part 2.

This is performed in one step, in which the elevating body 8 is lowered once. Moreover, since the drawing process is performed using the swing punch 11 and the drawing die part 17 before the bending process, the side plate part 2 is connected to the die 6, the swing pad 10, and the swing punch 11.
The bending process of the side plate part 2 is performed in a state where it is held between the two, and the formability of the bending process is improved.

性が向上する。C9 Effects of the Invention As described above, the device of the present invention has a support surface on the upper surface on which a portion near the edge of the upper plate of the workpiece is placed, and a drawing die portion for forming the four parts and the bent part; A die having a bending die portion and supported on a fixed base so that the recessed portion and the bent portion can move toward and away from the inner surface of the side plate portion of the workpiece on the support surface; a bend punch, which is disposed outside the side plate so as to be able to move toward and away from the side plate, and works with the bending die to bend the lower end of the side plate; an elevating body that can be raised and lowered upward; a pressing pad that is supported by the elevating body so as to be vertically movable relative to each other and is elastically biased downward, and works with the support surface to pinch the upper plate portion; a swing pad that is swingable in cooperation with the die to pinch the side plate portion and supported by the pressure pad; a swing pad that is swingable in cooperation with the drawing die portion of the die to form a recessed portion; A swing punch supported by a pad; as the elevating body descends, the die is rotated close to the side plate, the swing band is rotated close to the side plate, the swing punch is rotated close to the side plate, and the bend die is rotated close to the side plate. and a drive cam mechanism that sequentially rotates the side plate toward the side plate.
It is now possible to perform drawing and bending on a workpiece in a single step of lowering the elevating body once. Moreover, since the bending process is performed using the bend die while the side plate portion of the workpiece is held down by the swing punch, the formability of the bending process is improved.
