[Detailed description of the invention] This invention relates to a bending die in a press brake, and more specifically, the longitudinal length of the upper die is kept short while the upper and lower dies approach and separate before and after bending a plate material. This invention relates to a press brake bending die whose longitudinal length increases to a desired length while a plate material is being held between the upper and lower dies.

初めに本考案の実施例装置が卓効を奏する加工
例を第1図によつて説明する。
First, an example of processing in which the apparatus according to the embodiment of the present invention is highly effective will be explained with reference to FIG.

To perform such box bending, for example, the upper bending line 7 of the long side 5 of a flat plate material is bent, and then the lower bending line 9 is bent.
Next, the upper bending line 7 of the opposing long sides 11 is bent, and then the lower bending line 9 is bent, thereby providing the flange portion 3 and completing the processing of the two opposing sides in a groove shape. The processing up to this point is the lower end 1 of the upper mold 13.
There is no problem in taking out the semi-finished product since there is no obstacle to aligning the folding line 5 with the desired bending line.

In reality, pressure is concentrated at both ends of the upper die 13 in the longitudinal direction, and the thickness of the upper die in the orthogonal direction is not thin, so it is impossible to rotate the semi-finished product described above and attach/detach it diagonally. Therefore, it is extremely dangerous to hold the board while the upper and lower molds are approaching.
