Let it. In this state, the feeder 23, the press machine 28, the cutting machine 49, and the bending machine 46 are operated in the same manner as in the molding operation described above, and the molding operation is performed on a trial basis. Here, since burrs are generated at the cut ends of the cut pieces 54 cut by the cutting machine 49, the slender body 21 is pushed back to the supply side by the accumulated amount of the burrs due to the accumulation of the paris.

It is easy to deal with the problem simply by moving the press machine 28 by the moving device 43. Furthermore, due to the relationship between the length of the cut piece 54 and the processing position of the processing hole 12, the center of action of the driving force applied to the punch holder 34 from the lifting device may be displaced from the center of the punch 33. In the past, since the position of the press processing machine 14 could not be changed, the press work had to be performed while an eccentric load was applied, which led to a shortened life of the die set 15 and a failure of the device. .

  • the cutting machine 49 is arranged close to the bending position of the bending machine 46 (the installation position of the die 50) as described above, the number of cut pieces 54 existing between them is reduced. As a result, it is possible to reduce the amount pushed back by the burrs described above, and in particular, when the cut piece 54 is cut obliquely in the width direction, it may sink under the adjacent cut piece 54 or Riding situations can be effectively suppressed.
  • the distance between the processing center of the press machine 28 and the bending position of the bending machine 46 is adjusted in this way, the same forming operation as described above is repeated, and the cut pieces 54 are successively formed into a predetermined shape. It is bent.
