摘要： PROBLEM TO BE SOLVED: To perform the bending of the peripheral part and the recessing formation in the inner part of this surface with one set of a device by gradually bending while followingly rotating bar-like upper and lower punches with sliding with a sheet to be worked and thereafter, continuously and gradually stretching. SOLUTION: In the bending of the peripheral part, after shifting a supporting base provided on a hollow movable table 20 moved in two directions to almost the center part of the movable table 20, the sheet to be worked is laid. After pushing the sheet to be worked to the supporting base with the upper punch having a sliding piece provided in a main shaft 16, the lower punch 15 is driven to the upper direction, and while pushing up the peripheral part of the sheet to be worked, the movable table 20 is repeatedly and relatively moved to the one direction and the peripheral part of the sheet to be worked is bent into as L-shape. Successively, the L-shaped bent part is interposed between the sliding piece and the lower punch, and at the same time of lowering the upper punch 15 provided in the main shaft 16, the sheet to be worked is relatively moved to the one direction and the tip part of the L-shaped bent part is pushed to sliding piece and bent into as U-shape.

摘要： PROBLEM TO BE SOLVED: To provide an NC data preparing method for preparing NC data for sequential forming in a short period of time.
SOLUTION: A machining table 20 comprises four divided sections, i.e., a depth side machining table 20A, a front side machining table 20B, a front part machining table 20C, and a rear part machining table. The machining table 20 is divided into four sections. The machining table 20 are divided into four sections, and independently movable from each other. A workpiece is moved on the machining tables 20A, 20B and 20C, respectively. After the workpiece is fixed on each machining table, the peripheral portion of the workpiece is bent by using upper and lower punches. The pattern data plotting the visible outline of at least one forming out of the bending and stretch forming is saved in a development for piercing in which piercing parts are indicated in a diagrammatic drawing by using the line type different from that of the line plan at the piercing parts.
