PROBLEM TO BE SOLVED: To improve the safety and work efficiency of the bending work of a workpiece plate using a press brake. SOLUTION: A lower die fixing table 2 is extended on a base 1 in the X-direction (right and left direction ) and a lower die 3 is fixed freely attachably and detachably on the upper surface of this lower die fixing table 2. Opposed to the lower die 3, an upper die 4 is provided ascendably and descendably in the Z-direction (up-and-down direction). In the rear of the lower die fixing table 2, a back-guide 5 which is struck against the end face of the workpiece plate W is provided movably in the Y-direction (back and fore direction). The back-guide 5 is provided with a back-guide plate attaching base plate 5a and two back-guide plates 5b attached to the back-guide plate attaching base plate 5a and constituted so that the movement in the Y-direction and stoppage are possible. As an attracting means of the workpiece plate W, a magnet 7 is attached to the back-guide plate attaching base plate 5a together with two back-guide plates 5b. COPYRIGHT: (C)2009,JPO&INPIT
