Description

[0033] The FIGURE schematically shows a bending machine 1 for bending round tubes 100, for example.

[0034] The bending machine 1 shown in the FIGURE is a so-called multi-groove bending machine. The bending machine 1 has a bending tool 3 forming a bending axis 5. The bending tool 3 has several bending templates 7 forming a bending radius, said bending templates 7 being arranged one above the other. In addition, a swing arm 9 pivotable about the bending axis 5 is provided on which the clamping jaws 11 are arranged which cooperate with the bending templates 7 in order to fix the round tube 100 to be bent.

[0035] A profile separating device 15 is arranged on a tool holder 13, the profile separating device 15 comprising a tool head 17 having a separating apparatus 19. In the exemplary embodiment illustrated in FIG. 1, the profile separating device 15 is arranged on the swing arm 9 and is thus pivotable by means of the swing arm 9.

[0036] The separating apparatus 19 has a cutout 21 forming a separating region, said cutout 21 extending as far as an edge of the tool head 17. Thus, an opening is formed through which the round tube 100 to be separated can be introduced in the radial direction of the round tube 100 and also in the radial direction of the tool head 17.

[0037] The bending machine according to the invention has a profile guiding device, which is not illustrated, by means of which the round tube 100 is movable in the vertical and horizontal direction such as indicated by the double arrow. In this manner, the round tube 100 can, on the one hand, be arranged in the corresponding bending template 7 and, on the other hand, can also be introduced into the cutout 21 of the tool head 17 of the profile cutting device 15 by means of a vertical movement. In the exemplary embodiment shown in the FIGURE, the separating apparatus 19 is configured as an orbital cutting device and has knife carriers, which are not illustrated, with cutting knife wheels arranged thereon which are guided around the round tube 100 to be separated during the cutting process and can be delivered in the radial direction of the round tube to be separated. In this manner, chipless separation of the round tube 100 can be effected.

[0038] In general, the tool holder 13 can be configured to have a bearing device by means of which the tool head 17 is rotationally mounted and/or displaceable in the horizontal direction.

[0039] The swing arm 9 and, if necessary, the tool holder 13 can be used to align the tool head 17 with respect to the round tube 100 so that when the round tube 100 is introduced into the cutout 21 and thus into the separating region, separation is possible at the desired position of the round tube 100.

[0040] In the exemplary embodiment shown in the FIGURE, the profile separating device 15 engages the round tub 100 in the tube direction downstream of the bending template 7 and performs the separating cut there. However, in general, the tool head 17 can also be arranged at a different point on the round tube 100.

[0041] For example, the bending machine 1 may have a profile sliding device 23 arranged upstream of the bending tool 3 in the longitudinal direction of the tube, with a crease smoothing device 25 cooperating therewith, and the tool head 17 may engage between the profile sliding device 23 and the bending tool 3.

[0042] The bending machine 1 according to the invention and the profile separating device 15 arranged thereon can be used to produce bent tube sections of a round tube 100 in a particularly advantageous manner, wherein there is only little or no material scrap. This enables particularly economical production of the tube sections. The configuration of the bending machine 1 according to the invention shown in the FIGURE has the particular advantage that an already present profile guiding device is used for vertically feeding the round tube 100 to be separated to the profile separating device 15.

[0043] Of course, it is also possible for the tool head 17 to be moved by means of the tool holder 13 in the direction of the round tube 100 to be separated, for example by designing the tool holder 13 as a robotic arm.
