Since the side plates process the V-grooves inside the bending positions of the side plates for the bending operation, the bending grooves facilitate the bending operation.

The above-mentioned V-groove machining is mainly performed by hand, but this is a problem that machining workability of the side bands is low. Recently, machining is carried out by using a V-cutter.

Such a conventional V-cutting device is configured to perform V-cutting at the bent position of the side band while moving the cutting means having the cutter blade rotated by the rotary motor at the upper portion of the working die.

However, in the above-mentioned conventional V-cutting apparatus, since the side bar is arranged at a predetermined position by the jig on the upper side of the working die and then subjected to the V-cutting process by the cutting means, there is no separate fixing means for fixing the side bar, So that the cutting position is not constant and the machining quality is deteriorated due to the defective cutting.

In addition, the cutting means also has a problem in that the overall workability is deteriorated because the worker moves the workpiece back and forth by hand.
