Definitions

  • the invention relates to a bending machine in the preamble of claim 1 specified Art.
  • each work sled points a sleeve-shaped part that reaches through the window and is set at the edge of the window.
  • On the work surface facing away from the back of the machine body table several intermeshing drive pinions are arranged.
  • One in the form of a sleeve Part of the work slide couples the rotatably mounted shaft a drive cam of the work carriage with each used drive pinion.
  • the edge of the window runs along an arc curvature concentric to the respective drive pinion.
  • Parallel to the edge of the window are U-shaped or T-shaped Guide grooves incorporated into the machine body table.
  • the work slide is selected in the angular position radially aligned with the axis of the drive pinion fixed. So that each work sled can be used differently Working positions along the material passage axis can be aligned is a tool-bearing Part of the work slide relative to the sleeve-shaped Part and pivotable to the drive cam and with additional Clamping screws can be fixed on the work surface.
  • An arched one Edge section of the window or a drive pinion only one work sledge is assigned at a time. The adjustment the working positions of the sledges is time consuming and requires several solving and fixing steps.
  • the invention has for its object a bending machine to create the type mentioned at the width the work sled independently short transverse distances between neighboring Tools on one and the same guideway and / or directions of movement oblique to the material passage axis the tools, e.g. for bending over, are possible.
  • each sledge can use the same bending point along the material passage axis from several working positions operate on the guideway so that each desired, e.g. motion component used for bending sloping from one side or the other to the material passage axis is possible.
  • each desired e.g. motion component used for bending sloping from one side or the other to the material passage axis is possible.
  • the profile section there is a flawless despite the curve and heavy-duty seat of every work sledge.
  • the work sledge are easy to move.
  • the profile section is technically simple and stable.
  • each profile section defined management level parallel to the work surface can be higher on a guideway or lower - based on the work surface - than than another section of the profile.
  • the Embodiment according to claim 3 advantageous. Every sledge is radial with its working axis to the center of the circle aligned.
  • the circle radius can be relatively large choose so that there is only a slight curvature of the guideway.
  • the embodiment according to claim 4 is favorable in terms of an unimpeded material passage along the material passage axis.
  • the embodiment according to claim 5 is functionally simple and reliable. To adjust a work sled, either to put him in a new working position or in a parking position bring the work sled with the transport element coupled and when reaching the desired position uncoupled again.
  • a bending machine B according to Figures 1 and 2 has a machine body 1, the standing work surface 2 defined.
  • the machine body 1 sits on a foundation 14. With the bending machine B becomes wire or band-shaped Material bent in front of the work surface 2 conveyed horizontally along a material passage axis 3 becomes.
  • Flat guideways are on the machine body 1 F1 to F3 attached which consist of sections a prism, a dovetail or one T-profile 12 exist.
  • the guideway F1 is in the Management level E (Fig.3) or parallel to the work surface 2 formed with an arc curvature K, preferably an arc of a circle, the center of which is relatively wide lies below the material passage axis 3.
  • On the Guideway F1 are several, e.g.
  • Every sledge defines a working axis A1, A2 that roughly perpendicular to a tangent to the curvature of the guideway F1 in the working position of the work carriage S1, S2 and also roughly parallel to the work surface 2 or to the management level.
  • the work slides S1, S2 are essentially each other same, so that only the work slide S1 explained becomes.
  • This has a guided on the guideway F1 Housing 4 and a working drive 5 for one in the working axis A1 movable tool carrier 6 on which (see Figure 2) a tool 13 is attached, with the the wire or band-shaped material is processed, e.g. by bending, cutting, punching and the like.
  • FIG rectilinear guideway F2 Below the material passage axis 3 is one in FIG rectilinear guideway F2 'indicated, the one further work slide S3 with its work axis A3 slidably mounted. Dashed lines indicate that instead of the straight guide tap F2 'also a curved one Guide track F2 can be provided, which like the guideway F1 with the concave side of its curvature K faces the material passage axis 3.
  • the guideways F1, F2, F3 can with their convex Point the curvature side to the material passage axis 3. It is also possible to use a guideway with its convex Side and the other with its concave side to the material passage axis 3 align. Every guideway F1 and F2 need not necessarily be approximately parallel to Material passage axis 3 lie, but could also in the drawing plane twisted to one side or the other be so that its one end closer to the material passage axis lies as its other end.
  • FIG 2 there is a central opening 1a in the machine body 1 indicated, behind which another level and rectilinear guideway F4 for further work slides S5 (working axis A5) is attached.
  • the tools of the Movable work sled on the F4 guideway work from the back of the machine body 1 with the tools 13 of the working sledge working in front S1 to S4 together.
  • the guideways F1, F2 and F3 indicated in FIG. 1 could also be connected to a full circle may be interrupted where the material passage axis 3 goes through. All guideways have then the same radius of curvature.
  • a sliding drive 7 provided for the work sled S1, S2, the one Drive 9 and a transport element 8, which at significant curvature K expediently along the Curvature, but also straight in the case of a very flat curvature could be moved.
  • this has a clutch 11 with which it for the purpose of adjustment) optionally with the drive element 8 can couple, and a clamping device 10, with which he is in the respective work position or also clamped in a parking position on the guideway F1 and locked.
  • the clutch 11 and the clamping device 10 can have their own, remotely controllable Drives may be provided. Expediently but the working drive 5 and possibly also the tool holder 6 used for this function, as with 3 is explained.
  • the profile section 12 (dovetail profile) on the work surface 2 of the machine body 1 attached, e.g. screwed tight. Its top defines the management level E for the work slide S1, where the curvature K of the guideway F1 in the guiding plane E lies.
  • the housing 4 of the work carriage S1 is in one Working axis A1 defining longitudinal shaft 15 of the tool carrier 6 e.g. slidably guided.
  • the work drive 5 which is attached to the housing 4, is located e.g. a hydraulic or pneumatic piston 25 which with the Tool carrier 6 is coupled and this back and forth shifts.
  • the transport element 8 is for example a link chain or a timing belt or another, element movable along a curved path, the in an arcuate groove 17 in the profile section 12 moves.
  • the driver 18 is part of the coupling 11.
  • the tool carrier 6 by means of the Piston 25 over the actual working stroke of the tool 13 adjusted back.
  • the clamping device 10 is in the rear part of the housing 4 of the work carriage S1 housed.
  • a by a spring 21 against a counter surface of the profile section 12 preloaded jaw 20 carries on the top a projection 23 on the nose 24 in the path of movement the underside of the tool carrier 6 lies.
  • the transport element 8 via the drive 7 ( Figure 1) the work slide S1 can be moved along the Adjust guideway F1.
  • FIG 3 is an alternative for the shift drive with the transport element 8 in the profile section 12 Transport element 27 in a curvature K following or if necessary also a straight groove 26 in the work surface 1 shown.
  • the transport element 27 is, for example a curved or straight rod attached to one Long side or on a bottom or top one Tooth 28 carries, with a pinion, not shown of the shift drive 7 cooperates.
  • At the The top of the transport element 27 is a pin 29 hinted at either in the manner mentioned above the work slide S1 or by means of another, Auxiliary device, not shown, with the work carriage S1 can be coupled to the work slide S1 to adjust on the guideway F1.
