- This moves the bending tool 110 in the subsequent bending positions and acts against the underside 116 of the sheet 46 in such a way that this in a first bending direction 232 from the clamping plane 114 upwards, the is bent in the direction of the upper beam 64.
- the bending of the flat material 46 can, as in Fig. 8 shown, as long as the flat material 46, such as shown in Fig. 8, on a at an acute angle to Einspannesebene 114 extending oblique front surface 234 of the upper clamping tool 66 is applied.
- the bending tool 110 has a neck 240 which extends connects to the bending tool carrier 112.
- the neck 240 wears in turn, a bending nose 242, which to the actual Performing the bending operation is used.
- the bending nose 242 extends from the neck 240 in the direction of Clamping tools 26, 66, that a bending tip 244 always at least one of the clamping tools 26, 66 faces and starting from the bending tip of the nose, the bending nose 242 from the respective clamping tool 26 and / or 66 away extends.
- the bending nose 242 carries as a whole 246 designated printing surface, with which the bottom 116th of the flat material 46 can be acted upon.
- the printing surface 246 comprises a bending tool carrier 112 facing away from arranged upper partial pressure surface 248, with which the bending nose 242 in the bending start position first the bottom 116 of the Flat material 46 touched.
- the front partial pressure surface 248 is bent to one at the bending tip 244 lying crest line 250. Starting from the crest line 250 then still extends a rear partial pressure surface 252nd the pressure surface 246 on a bending tool carrier 112 facing side of the bending nose 242 of the bending nose tip Away.
- the Biegenase 242 plant at the bottom in this case 116 of the sheet 46 is a substantially linear Plant, which predetermined by a contact line 254 is, which is parallel to the longitudinal direction 14 and thus also extends in the longitudinal direction of the bending tool 110.
- a contact line 254 is, which is parallel to the longitudinal direction 14 and thus also extends in the longitudinal direction of the bending tool 110.
- the Biegeusings ein is, as shown in Fig. 9, the Contact line 254 on the front partial pressure surface 248, and while at a maximum distance from the apex line 250.
- the flat material 46 bent out of the clamping plane 114 so migrates the contact line 254 on the front partial pressure surface 248 in the direction of the crest line 250 and then coincides with the Crest line 250 together when the sheet 46, for example by an angle of the order of 90 ° the clamping level 114 has been bent out.
- the sheet 46 passes over this angle the contact line 254 across the crest line 250 and then migrates to the rear partial pressure surface 252 at which it rests in all bending positions in which a bend of the flat material 46 with respect to the clamping plane 114 um an angle of more than 90 ° is done.
- the determination of the web 260, with which the bending nose 242 from the initial bending position to the final bending position moves takes place by appropriate determination of the dimensions the knee lever drive system 152, in particular the lengths of Drive arm 154 and the arm 158 and the dimensions the retaining rod 122 and the distance of the bending nose 242 of the pivot axis 142.
- the blocking device 208 allows, as already described, different extended positions of the toggle mechanism Adjust 182, as in Fig. 10 and 11 again clearly is shown.
- the toggle mechanism 182 In the first, in Fig. 10 shown extended position the toggle mechanism 182 is not in its maximum Extended position, but has a length that is less as the maximum possible length while, for example, in the second, in Fig. 11 shown extended position, the Length of the toggle mechanism 182 is maximum.
- the bending tool 110 each in the initial bending position should stand. For this reason is at the second extended position of the toggle mechanism 182 the Sliding link 198 set with the actuator 206 so that this closer to the upper portion 38 of the front wall 28 of the Lower beam carrier body 22 is than in the first extended position.
- the bending machine does not only include the lower one Bending tool 110 and the lower bending tool carrier 112 with a associated bending tool moving device 120, but also still in addition, an upper bending tool 310, which on an upper bending tool carrier 312 is held, wherein the upper bending tool 310 by a bending tool moving device 320 is movable, in the same preferably identical manner is formed, as the bending tool movement device 120th
- the bending tool moving device 320 also includes Retaining rods 322, which function in the same way as the retainer 122, and attack the upper cheek 64 in this case.
- the bending tool carrier drive units 350 are formed in the same way, like the bending tool carrier drive units 150, but in this case the upper beam carrier body 62 is arranged.
- the upper bending tool 310 is capable of the same Perform bending operations, such as those associated with the lower bending tool 110 have been described.
- a bending operation performed with the lower bending tool 110 so is the upper bending tool 310 in the rest position, in which it in a depression 224 corresponding recess 424 engages in the upper beam 64.
- the upper bending tool 310, the upper Bending tool carrier 312 and also the upper bending tool movement device 320 are near the upper cheek 64 and lie close to the front wall 74 of the upper beam carrier body 62,
- There is a bending clearance above the effective bending edge 106 280 between the upper bending tool moving means 320, the upper bending tool carrier 312 and the upper Bending tool 310 and the clamping level 114 which is starting from the clamping level 114 over an angular range ⁇ of about 135 °.
- the lower bending tool carrier 112 does not move in the form of a pivoting movement about the effective bending edge 106 - as is the case in the prior art - but remains in all possible bending positions of the lower bending tool 110 in one between a perpendicular to the clamping plane 114 and by the lower bending tool 110th extending front boundary plane 282 and the lower beam support 20th lying action space and also the bending tool movement device 120th remains in this action space without reaching beyond, so that so
- the flat material 46 can be handled easily or a combination of multiple machines in a simple manner is possible.
- the action space is even smaller and lies between one the respective effective bending edge 104, 106 therethrough and perpendicular to the clamping plane 114 extending front plane 286 and the Unterwangenarri 20th
- the lower bending tool 110 with the bending tool carrier 112 into the rest position which, for example, in Fig. 5 is shown. Also in this rest position of the lower bending tool 110 exists between the clamping plane 114 and the lower bending tool moving means 120, the lower bending tool carrier 112 as well the lower bending tool 110, a bending space 284, which is also over an angular range a of approximately 135 ° with respect to the clamping plane 114 extends, so that even with the upper bending tool 310, a bending of the Flat material 46 opposite the clamping plane 114 to the bending edge 104th of the lower clamping tool 26 by an angle of up to 135 ° possible is.
- the bending machine is a bending of the Flat material 46 from the clamping plane 114 out in two opposite Directions, namely towards 290 upwards or towards 292 down from the clamping plane 114 out possible, where to bend in Direction 290 the lower bending tool 110 and for bending in the direction 292 the upper bending tool 310 are used, while the respective other bending tool 310 or 110 for creating the respective Biegeokraums 280, 284 is at rest and the respectively active bending tool carrier 112, 312 remains together with the associated bending tool movement device in the Action space between the front level 286 and the respective Wang bearer 20, 60.
- the bending machine according to the invention allows the Performing multiple bends of flat material, for example first in the direction of 290 and then in Direction 292, and then possibly back towards 290, wherein each of the bending clearances 280 and 284 between the front plane 282 and the other bending tool carrier 312 and 112 are advantageous, since so despite existing bends in the same direction, an additional Bend without hindrance is feasible.
