PROBLEM TO BE SOLVED: To perform bending and drilling at a single setup, and optionally select the shape of holes. SOLUTION: A combined processing device 1 is made up of a bed 2, a drilling mechanism 10 provided on the bed 2, a work fixing die 19, a bending mechanism 20 provided at the outlet side of the bed 2, and a core iron (not shown). A work 4 is a hollow material. Thus, holes are punched or drilled in the work, using the core iron as a die. Then, the work is bent by the bending mechanism. Thus, drilling and bending can be performed at a single setup, and the processing time can be shortened and the related equipment can also be miniaturized. |
