Definitions

  • the above invention relates to a machine for bending of strand-like material, e.g. Pipes, rods Profiles or metal wire, according to the preamble of claim 1 (see z. B. EP-A-0466 819).
  • strand-like material e.g. Pipes, rods Profiles or metal wire
  • a controlled movable one is for the advance of the pipe Carriage provided along the parallel guides of the Machine bed is movable.
  • the car is with one Provided chuck that allows the pipe to be closed tighten. Furthermore, the chuck allows a precise, controlled rotation of the pipe around its longitudinal axis.
  • the known bending machines are robot-like Gripping devices, slides or conveyor belts assigned with which the bent workpiece is removed becomes.
  • the shaft is a variety of bending shapes with different bending radii slidable in the direction of the longitudinal axis of the receiving shaft around the selected bending shape into a desired one Bring work position, i.e. in accordance with the Axis of the pipe to be bent.
  • a device for performing such displacement movements is from a technical point of view complex and requires control and drive devices for an exact position alignment of the shaft together with the Bending forms compared to the pipe to be bent.
  • the known bending head can have two or at most take up three different bending shapes. But it did shown that it is for the operator of the machine would be desirable over a larger number of Bending forms available instantly and without interruption how the machine works are available to thus a larger number of bending processes to be able to perform different bending radii.
  • the object of the above invention is a Propose bending machine with a large number different bending forms is equipped, the various forms of bending with the greatest speed and Accuracy can be brought into the working position Bending head is designed so that a gentle and exact placement of the machined workpieces Implementation of the bending process becomes possible.
  • this object is achieved using a Machine for bending strand material, such as Pipes, rods, profiles or metal wire with the features of claim 1.
  • a Machine for bending strand material such as Pipes, rods, profiles or metal wire with the features of claim 1.
  • the bent workpiece can also be optionally on the right or to the left of the machine bed.
  • the bending machine has which is generally identified with 1, a T-shaped one Machine bed, which consists of an elongated section 2 and a cross strut 3, which is the front end of the Machine bed 1 forms.
  • the guides 4 movably accommodate a carriage 5 which has a chuck 6 for tensioning a tube 7.
  • the tube 7 can about its longitudinal axis, which is schematically marked with (x).
  • the cross strut 3 of the machine bed 2 has on it Front a vertically aligned wall 8, which in a wall piece 9 merges, which slopes forward extends.
  • the wall piece 8 takes a precision guide 10, and on lower end of the inclined wall 9 is a further precision guide 11, arranged.
  • a carriage 12 In the space that is delimited by walls 8 and 9 a carriage 12 is used, which has a prismatic shape.
  • the carriage 12 is supported on the Precision guide 10 from and on its underside is the Carriage 12 on the precision guides 11.
  • the Carriage 12 Using e.g. a ball screw 40 which by a controllable motor 41 driven aird, the Carriage 12, as shown with the double arrow (f), be moved.
  • a ball screw 40 which by a controllable motor 41 driven aird, the Carriage 12, as shown with the double arrow (f), be moved.
  • the carriage 12 takes a bearing body 13 on, e.g. with the help of a horizontal arranged shaft 42, which is in strong precision bearings is arranged, which is arranged inside the body 13 are a bending head, the total of 14 is marked.
  • the horizontally arranged shaft 42 has a ring gear 43 connected, which is arranged in the receiving body 13; the Gear ring 43 is controllable with the help of a Motor 44, which is arranged inside the carriage 12, driven (see Figure 5).
  • the bending head 14 receives a column 15, which is stationary is arranged opposite the body of the bending head 14; the protruding ends 16 of column 15 take a plurality of Bending forms 17, 18.
  • the bending shapes have different bending diameters on.
  • Each bending shape group 17 or 18 is a known per se and associated pivotable bending arm, which only shown schematically and labeled 19 and 20 respectively is.
  • the bending arms 19, 20 are mounted such that a Swiveling around the axis of the shaft 15 is made possible.
  • the column 15 receives a ring gear 45, which is rotatably mounted and with the help of a controllable motor drivable to carry out a Pivotal movement is.
  • the machine can be seen from the front in FIG. 2 become.
  • the carriage 12 was left on the precision guides 10 and 11 moved and the bending head 14 was around the axis (Y) of the shaft 42 of the bending head 14 is pivoted thereby to ensure that the upper of the bending shape group 17 Bending shape 17 'is positioned opposite the tube 7 and the implementation of a bending process with the help of the swivel arm marked with 19 is made possible.
  • the figure 4 can the chuck 6 of the carriage 5 and that tube 7 to be bent. Furthermore, they are Parallel guides 10 and 11 visible on the Front of the cross strut 3 of the machine bed, the is generally identified with 1, are arranged.
  • the ball screw 14 is driven by a controllable motor driven, which is under the control of an NC facility of the machine.
  • the motor 44 is also via the NC device of the machine 1 controllable, thus it becomes possible to turn the bending head 14 around to pivot an accurate and predetermined angle, or to turn the bending head 14 through 360 °.
  • the rotatable ring gear 45 is in with a gear Operatively connected. This gear is controlled by a Motor (not shown in Figure 5) driven. Also this controllable motor is with the NC device Machine 1 operatively connected.
