折曲成形は通當ベンダーやプレス機を利用して個別に行
っているのが一般的である。(Prior Art) Conventionally, when bending a bar material, bending at one or a few locations is generally performed individually using a continuous bender or a press machine.
ところで、一本の棒材において折曲１１ＭＩ所が多数に
なるときは作業効率上、」二記したヘンダーやプレス機
等を複数組合せた専用機が用いられている。By the way, when a single bar has a large number of bends (11MI), a special machine combining multiple henders, presses, etc. mentioned in "2" above is used for work efficiency.

高コスト化を招いてしまう。(Problems to be Solved by the Invention) However, such conventional technology has the following problems. In other words, since the dedicated machine is individually designed for each bar material to be formed, it becomes larger and more complex in proportion to the number of bending points, and the '0:J strain increases greatly. In addition, the molding range (degree of freedom) is also limited. In addition, such specialized machines have extremely low versatility because they are manufactured uniquely for each forming bar, and if the type of forming bar is different, a new specialized machine must be prepared, and further This results in higher costs.
