Definitions

  • the invention relates to a pipe bending machine with a bending template rotatable about a vertical axis, one swivel arm pivotable about the axis of the bending template, the one clamping jaw for clamping a pipe section on the bending template, and one Slide rail, which is an abutment for the unbent Has pipe section.
  • the known pipe bending machines have a rotatable one Bending template that has a bending groove on its circumference has a part of the cross section of the bends pipe.
  • the pipe will start from one a swivel arm attached to the bending tube groove pressed. If the swivel arm at the same time Rotation of the bending template around the axis of the Bending template swiveled around, so the tube is around pulled the bending template around, making a pipe bend is produced.
  • For pipes that are straight at first it doesn't matter whether the pipe bend to the right or to the left. However, it often happens that Pipes must be bent in opposite directions, namely with a right turn and then a left turn. These bends can be very intense are close to each other. In such cases, after the first bend has been made, the pipe not be rotated to create the second bend because such a rotation through the parts of the Bending machine is prevented.
  • a pipe bending machine is known from FR-A-2 076 144, with the pipe to be bent from opposite sides can be applied to the bending template.
  • the Pipe bending machine is suitable for right and left bending, however, the suitability of a single bending template for both left and right legation is not described. In addition, must at different Bending radii in both directions are different Bending template must be used.
  • the pipe bending machine also has a pivotable swivel arm a clamping jaw, which the pipe to be bent against the Bending template presses.
  • a slide rail as an abutment is not for the pipe section not to be bent intended. Such a slide rail is with others Pipe bending machines known only for bending in one direction (GB-A-2 082 949).
  • the invention has for its object a pipe bending machine to create with the without assembly work complicated pipe shapes are also produced on the machine where bends are very close to each other connect.
  • the The swivel arm can be swiveled a full 180 ° and the Bending tools are designed so that they both suitable for right bends as well as left bends are. Accordingly, a pipe can either be from the left or attached to the right side of the bending template become. For right turn and left turn is each a separate slide rail is provided, which as Abutment or lateral support for the unbent pipe section is used.
  • a pipe can be used with the Pipe bending machine according to the invention with both Right bend as well as a left bend , it is also possible to move the pipe around beforehand to rotate the longitudinal axis of the pipe clamping device.
  • the pipe bending machine allows because of the choice of Direction of rotation the production of complicated pipe shapes with a single machine or even further processing pre-bent pipes made with a machine that has only one direction of bending, not be bent could.
  • the pipe bending machine has a bending head 10, with an arm 11 from an end wall of the machine frame 12 protrudes horizontally.
  • the arm 11 can on the Front wall of the machine frame 12 in horizontal Direction are moved, as indicated by arrow 13 and also in the vertical direction.
  • the bending template is located at the front end of the arm 11 14, which consist of two superimposed Template parts 15 and 16 there. Every template part has the shape of a substantially cylindrical thick washer, with a Bending groove 17 and 18 is provided. The bending groove extends However, the entire scope of the Template part, but it ends in a tangential Clamping piece 19 or 20.
  • a Swivel arm 21 mounted radially from the bending template protrudes. Is located on this swivel arm the clamping jaw, which is operated by a (not shown) Linear drive can be moved along the swivel arm 21 can.
  • the clamping jaw has two jaw parts 23 and 24 on that side by side, but in different Heights are arranged.
  • the lower jaw part 23 is located at the same height as the lower template part 15 and the upper jaw part 24 is located at the same height as the upper template part 16. Both jaw parts are moved back and forth together, however, it is also possible to use the cheek pieces to control individually.
  • each of the jaw parts 23 and 24 has a groove 25 and 26, which is part of the Includes circumference of the tube to be bent 27, while another part of the scope in the corresponding Bending groove 17 or 18 of the bending template 14 is located.
  • the template part 15 is for clockwise rotation (clockwise) provided, i.e. from its clamping piece 19 from the bending groove 17 extends counterclockwise.
  • the template part 16, however, is for left turn provided, i.e. extends from its clamping piece 20 the bend groove 18 clockwise.
  • Both Clamping pieces 19 and 20 are on the same side of one Diameter 28 of the bending template 14 and on both sides a transverse to the jaws, the axis of the bending template 14th containing level.
  • Slide rail supports 30 and 31 From the arm 11 are on opposite sides Slide rail supports 30 and 31. Every slide rail carrier 30 carries a slide rail 32 and 33, respectively runs parallel to the arm 11 and serves the purpose of Pipe bending to absorb the generated counterforce of the pipe and support the tube 27 laterally.
  • the slide rails are each driven by a drive device Slide rail carrier 30.31 movable.
  • the slide rail 32 is effective when the jaw part 23 is used is coming. It is therefore at the same level as the jaw part 23 and the template part 15.
  • the slide rail In contrast, 33 is arranged higher. she comes used when the tube 27 to the opposite Side of the bending template is attached and the jaw part 24 is used.
  • Each of the slide rails 32 and 33 is also one Longitudinal drive provided to the tube during the bending process to succeed.
  • the position of the swivel arm 21 is transverse to the clamping jaw 22 aligned with the arm 11 and the direction of the tube 27 and it is on the left side of the bending template 14.
  • the lower jaw part 23 is on the left side of the diameter 28 arranged and that Cheek piece 24 on the right side. Will the jaw 22 advanced, the tube between the Jaw part 23 and the clamping part 19 clamped.
  • Rotation of the bending template 14 is carried out a right bend of the pipe 27.
  • the tube becomes 27 attached to the opposite side of the bending template, namely at the level of the upper part of the template 16.
  • the swivel arm 21 is then in the 180 ° pivoted position 21a.
  • the lower jaw part 23, that is not used protrudes under the front end of the Slide rail 33. If the clamping jaw 22 is advanced, so the upper jaw part 24 presses the tube against the upper template part 16.
  • the upper slide rail 33 is advanced to support the pipe laterally. Then takes place from position 21a of the swivel arm Left turn, with a portion of the tube around the Template part 16 is pulled around and thus bent.
