Figure 13 represents to change the action of the special-purpose bending dies 321,322 in 2 ends of movable side.This figure (A) expression is walked out bender main body 1 with the running body 21 that makes like that Fig. 8, Fig. 9 narrated, and with the state of the special-purpose bending dies 32 in the mobile ends of the butt parts 23 of movable side.After this, the push mechanism 26a that falls with pushing mechanism 26 as shown in Figure 10 when picture advances, when being loaded into bending die 3 on the bending die keeping platform 25, the special-purpose bending die 321 in the end on the running body 21 is pushed parts 26a and is loaded on the movable keeping platform 54 (Figure 13 (B)).
Return back (Figure 13 (C)) at push mechanism 26a, when changing special-purpose bending dies in 2 ends 321,322, with movable keeping platform driving and reversing mechanism 56 movable keeping platform 54 is moved, the special-purpose bending die 322 in the end that the next one will be loaded is positioned at (Figure 13 (D)) on the end type pushing mechanism 55 pairing positions.After this, make the special-purpose bending die 322 in end on the movable keeping platform 54 on running body 21, move (Figure 13 (E)) with end type pushing mechanism 55.
In addition, since the 3b of the portion that is stuck of the butt parts 23 of special-purpose bending die 321,322 in end and movable side and holding section 23b with the direction of running body direction of travel quadrature on engage, break away from free, combination, disengaging are carried out in the action that therefore utilizes push mechanism 26a and end type pushing mechanism 55 to promote the special-purpose bending dies 321,322 in ends.
When image pattern 12 makes the end of the crooked module 3A that butt parts 23 are over to replacing move like that, by the special-purpose bending die 322 in end after the mobile like that replacing of image pattern 13 (E), the special-purpose bending die 32 in the end of the movable side of crooked module 3A is replaced with the special-purpose bending die in the different end of model width.
When not changing the special-purpose bending die in end 321,322, the action of omitting the movable keeping platform 54 of moving of Figure 13 (D).Thus, the special-purpose bending die 321 (322) in end that is loaded on the movable keeping platform 54 still continues on for crooked module 3A.
If adopt the bender of the band bending tool length adjusting mechanism of this structure, the form of adjusting the length of bending die 3 like this can degree of gaining freedom.Especially because crooked module 3A has the special- purpose bending die 31,32 in the end that lays respectively at two ends, the end that the crooked module of the top end face of the special-purpose bending dies 31,32 in these ends is arranged becomes be the curved face part 3a of curve in the cross section of bending die orientation, even therefore the length of crooked module 3A is carried out various changes, can both make crooked module 3A two ends have circular arc, can carry out the processing that the corner part at the peristome 92 of Figure 15 has the curved tabs 93 of fillet 93a.At this moment, because butt parts travel mechanism 24 can make the special-purpose bending die 32 in the end far away with respect to bender main body 1 move to the position of the end of the maximum spread length of leaving the bending die 3 on the bending die keeping platform 25, therefore can use the special-purpose bending die 32 in end and not produce problem such as interference, the bending die 3 in the middle of changing successfully.
