Definitions

  • the invention relates to a bending machine with a work area for bending elongated workpieces, in particular of wires, pipes, rods or the like., Which are supplied by a delivery device.
  • the DE 19628392 A1 describes a bending machine in which two bending towers and a central gripping unit are mounted on a machine bed.
  • the bending towers as well as the gripping unit can be moved on the machine bed.
  • rotatable bending heads are mounted around the workpiece axis.
  • this known bending machine however, only bends in the workpiece axis can be performed, always additional supply and discharge units are needed.
  • a large number of gear elements are needed to operate the bending heads and the gripping unit limits the bending space in the working area of the machine.
  • each gripping unit is provided with two grippers, which can grip on both sides of a flexible part.
  • the bending head is attached to a kind of robot, which can be designed very differently.
  • the first gripping unit removes the workpiece from a feeder and pivots it into the work area (bending area) of the bending machine. There, the first half of the workpiece is bent. With the second gripping unit, the workpiece can then be rotated by 180 °, after which then the other half of the workpiece can be provided with bends.
  • this known bending machine has only a relatively low power.
  • the bending head used only allows the drawing bending process.
  • the overall machine is very complicated in construction.
  • a handling device for bars in a bending plant is from the DE 603 01 913 T2 known.
  • the grippers are also pivotable about an axis parallel to the workpiece axis.
  • the bending heads are also movably mounted on a guide bed.
  • the gantry structure of the transport device requires a very large amount of space.
  • the grippers can not be moved independently of each other to the delivery device (magazine), which in turn reduces the performance of the known machine.
  • a plurality of bending stations is used in succession, which are arranged hanging from above, which in turn requires a relatively large frame.
  • a plurality of pivoting grippers are provided for transferring the workpieces between the individual bending stations, wherein the gripping mechanism executes a curved path to pick up the pipe from the previous station and pass it on to the downstream station after bending.
  • the large frame here is also a disadvantage that no additional fixation of the workpiece is provided in addition to the swivel gripper used in each case.
  • a bending machine for machining workpieces in several stations, each station having a central gripping unit and two laterally mounted therefrom bending heads.
  • the bending heads and the gripping unit are each movable on a common guide bed.
  • a pivotable transfer device is also provided, with which each workpiece can be pivoted from the first station to the second parallel station.
  • This transfer device can also be the gripping unit at the same time.
  • the machine works serially out of a magazine. Due to the almost closed, round bending head disc of the known bending machine, however, bends greater than 90 ° are not possible, and sometimes even a boom is used as a bending tool. This creates long straight sections in the middle of a workpiece. The inserted bending head allows only a roll bending.
  • the present invention seeks to provide a bending machine, which is particularly suitable for bending elongate workpieces, the high performance and space-saving and relatively simple design and the machining of workpieces with multiple flexible sections and pre-assembled workpieces (with nuts , Sleeves, etc. are provided).
  • a bending machine with a work area for bending elongate workpieces, in particular of wires, tubes, etc., which are supplied by a delivery device, with a base frame, which has a front side facing the delivery device and a rear side facing away from this, wherein the base frame in the work area two bending robots on a common, centrally mounted on the base guide rail parallel to the longitudinal direction of the base frame movably arranged and further - viewed in the longitudinal direction of the base frame - at the front of the base frame approximately in the middle of a holding forceps and on both sides thereof in each case parallel to the bending robots movable auxiliary gripper and on the back of the base frame also approximately centrally, but laterally offset to the holding forceps, an outlet gripper are provided, wherein the auxiliary gripper, the holding forceps and the discharge gripper in each case in an inner pivoting position in which they hold in the working area of the bending machine above the guideway and between two bending robots each a workpiece
  • the bending machine In the case of the bending machine according to the invention, initially there is a central construction of the machine concept: all working units are attached to the central base frame. Due to the arrangement of the common for the two bending robot track centrally on the base frame and the side thereof provided arrangement of the gripping and holding forceps on the front or back of the base frame is given the possibility that in the work area, the two bending robots, which also centered sitting on the base frame, are not disturbed in their process by the laterally mounted gripping devices or the holding gripper. The grippers can be moved completely independently of each other, but of course the auxiliary grippers can also be moved in parallel with the bending robots.
  • the bending machine With the bending machine according to the invention, it is possible, even long workpieces (in a length of up to 6 m), such as lines, pipes, rods, wires, rods, flex cables, etc. can be bent quickly and inexpensively.
  • the delivered by the delivery device workpieces are at least by means of the two auxiliary gripper, possibly also additionally detected by the holding forceps, and then pivoted into the work area at the top of the base frame above the track for the bending robot. There then the workpiece can be provided by the two bending robots from its two end sides towards the center with bends, the bending robots are designed so that they are arbitrarily positioned to the workpiece and this can bend in any plane.
