Definitions

  • the invention relates to a bending machine of the type specified in the preamble of claim 1.
  • the guideways for the work slides which are arranged on both sides of the material passage axis, are flat and rectilinear prismatic strips which are fastened to the machine body and lie parallel to the material passage axis.
  • the work slides are moved in a straight line between the work positions and fixed again.
  • the set-up times for adjusting the work slides in this bending machine are advantageously short; however, the tools placed on the tool carriers cannot be placed as close to each other as would be desirable for certain bending programs.
  • the necessary distance between the tools in the guide direction depends on the width of the work slide.
  • the invention has for its object to provide a bending machine of the type mentioned, in which, despite short set-up times for adjusting the work slides regardless of the width of the work sled, short transverse distances between adjacent tools and or directions of movement of the tools oblique to the material passage axis, e.g. for bending over, are possible.
  • each working slide can serve one and the same bending point along the material passage axis from several working positions on the guideway, so that the desired movement component, which is used, for example, for bending over, is possible from one side or from the other at an angle to the material passage axis.
  • each working slide is aligned with its working axis radially to the center of the circle.
  • the embodiment according to claim 3 is also advantageous because the work slides on both sides of the material passage axis can be adjusted so that the tools work as close to one another and / or inclined movement components are possible.
  • the management level can be parallel to the work surface, whereby the management level of a guideway can be higher or lower - based on the work surface - than the management level of another guideway.
  • the embodiment according to claim 4 is particularly advantageous with regard to tools to be placed as close as possible to one another.
  • the embodiment according to claim 5 is advantageous.
  • the radius of the circle can be chosen to be relatively large, so that only a slight curvature of the guideway arises. Nevertheless, the tools can be placed closer together and with oblique movement components than is specified by the width of the work slides.
  • the embodiment according to claim 6 is particularly useful when several bending tools have to work very closely together and locally concentrated.
  • the embodiment according to claim 7 is advantageous for an unimpeded passage of material.
  • the embodiment according to claim 9 is technically simple and stable. In spite of the curved guideway, a perfect and highly resilient seat of each work carriage results. Furthermore, the work slides can be moved easily.
  • the embodiment according to claim 10 is functionally simple and reliable. To adjust a work carriage, either to bring it into a new work position or into a parking position, it is coupled to the transport element and uncoupled when the desired position is reached.
  • the embodiment according to claim 11 is advantageous because the working drive of the work carriage is used simultaneously for coupling and uncoupling.
  • the embodiment according to claim 12 is also structurally simple because the tool carrier assumes a dual function and couples the work slide to the transport element.
  • the embodiment according to claim 13 is advantageous because the working drive also operates the clamping device, so that no additional auxiliary drives are required both for coupling and for clamping.
  • the system is expediently designed in such a way that the working drives operate additional lifting distances which are not used in the normal working of the tool carriers, so that there is no overlap between the working function and the transport or clamping function.
  • a bending machine B according to FIGS. 1 and 2 has a machine body 1 which defines a standing work surface 2.
  • the machine body 1 is seated on a foundation 14.
  • the bending machine B is used to bend wire or strip-shaped material that is in front of the work surface 2 is conveyed horizontally along a material passage axis 3.
  • Flat guideways F1 to F3 which consist of sections of a prismatic profile, a dovetail profile or a T-shaped profile 12, are attached to the machine body 1.
  • the guideway F1 is formed in the guide plane E (FIG. 3) or parallel to the work surface 2 with an arc curvature K, preferably an arc of a circle, the center of which is relatively far below the material passage axis 3.
  • Each working slide defines a working axis A1, A2, which is approximately perpendicular to a tangent to the curvature of the guideway F1 in the working position of the working slide S1, S2 and also approximately parallel to the working surface 2 or to the guide plane.
  • the work slides S1, S2 are essentially identical to one another, so that only the work slide S1 is explained.
  • This has a housing 4 guided on the guideway F1 and a working drive 5 for a tool carrier 6 movable in the working axis A1, to which (see FIG. 2) a tool 13 is attached, with which the wire or strip-shaped material is processed, e.g. by bending, cutting, punching and the like.
  • a straight guide track F2 ' is indicated in FIG. 1, which slidably supports another work slide S3 with its work axis A3.
  • a curved guide track F2 can also be provided which, like the guide track F1 with the concave side of its curvature K, faces the material passage axis 3.
  • a straight guideway F3' (in solid lines) lying approximately perpendicular to the material passage axis 3 is shown, which carries a further work slide S4 with the work axis A4.
  • a curved guideway F3 could also be provided (indicated by dashed lines).
  • the guide tracks F1, F2, F3 can point with their convex curvature side to the material passage axis 3. It is also possible to align one guideway with its convex side and the other with its concave side to the material passage axis 3.
  • Each guideway F1 and F2 does not necessarily have to be approximately parallel to the material passage axis 3, but could also be rotated to one side or the other in the plane of the drawing, so that one end is closer to the material passage axis than its other end.
  • an average opening 1a is indicated in the machine body 1, behind which a further flat and rectilinear guideway F4 for further work slides S5 (work axis A5) is attached.
  • the tools of the work slides displaceable on the guideway F4 work together from the rear of the machine body 1 with the tools 13 of the work slides S1 to S4 working at the front.
  • the guideways F1, F2 and F3 indicated in FIG. 1 could also be connected to one another to form a full circle which may be interrupted where the material passage axis 3 passes. All guideways then have the same radius of curvature.
  • a displacement drive 7 is provided for the work slides S1, S2, which has a drive 9 and a transport element 8 which, with a clear curvature K, expediently along the curvature, on the other hand with a very flat one Curvature could also be moved in a straight line.
  • the work slide S1 it has a clutch 11, with which it can be coupled with the drive element 8 for the purpose of adjustment), and a clamping device 10, with which it is clamped in the respective working position or in a parking position on the guideway F1 and locked.
  • Separate, remotely controllable drives can be provided for actuating the coupling 11 and the clamping device 10.
  • the working drive 5 and possibly also the tool carrier 6 are also used for this function, as will be explained with reference to FIG. 3.
  • the profile section 12 (dovetail profile) is attached to the working surface 2 of the machine body 1, e.g. screwed tight. Its upper side defines the guide plane E for the work slide S1, the curvature K of the guide track F1 being in the guide plane E.
  • the tool carrier 6 is, for example, guided in a longitudinal shaft 15 defining the work axis A1.
  • a hydraulic or pneumatic piston 25 which is coupled to the tool carrier 6 and moves it back and forth.
  • the transport element 8 is, for example, a link chain or a toothed belt or another, Element movable along a curved path, which moves in an arcuate groove 17 in the profile section 12.
  • a carrier 18 with a coupling recess (indicated by dashed lines) is attached to the transport element 16 and can be moved into a recess on the underside of the housing 4 transversely to its longitudinal direction.
  • the driver 18 is part of the coupling 11.
  • a nose 19 is provided as a counter-coupling element, which can be inserted into the coupling recess of the driver 18 and couples the work carriage S1 to the transport element 16.
  • the tool carrier 6 is adjusted back by means of the piston 25 beyond the actual working stroke of the tool 13.
  • the clamping device 10 is accommodated in the rear part of the housing 4 of the work carriage S1.
  • a jaw 20, which is biased by a spring 21 against a counter surface of the profile section 12, bears on the top a projection 23 which lies in the path of movement of a nose 24 on the underside of the tool carrier 6. If - as mentioned - the tool carrier 6 is moved backwards over the working stroke of the tool 13 to couple the working slide S1 with the transport element 8, then the jaw 20 is lifted from the counter surface 22 via the nose 24, while the nose 19 into the coupling recess of the driver 18 occurs.
  • the working carriage S1 can be adjusted along the guideway F1 by driving the transport element 8 via the drive 7 (FIG. 1).
  • the lugs 19, 24 with the tool carrier 6 are again moved in the opposite direction by the piston 25 adjusted, wherein the jaw 20 comes back to rest on the counter surface 22 and then the nose 19 emerges from the coupling recess of the driver 18.
  • the work slide S is locked in the new work position.
  • the driver 18 can be moved to another work slide.
  • FIG. 3 shows, as an alternative to the displacement drive with the transport element 8 in the profile section 12, a transport element 27 in a groove 26 following the curvature K or possibly also a straight groove 26 in the work surface 1.
  • the transport element 27 is, for example, a curved or straight rod, which has a toothing 28 on a long side or on an underside or top side, which interacts with a pinion of the displacement drive 7, not shown.
  • a pin 29 is indicated, which can be coupled to the work slide S1 in the aforementioned manner or to the work slide S1 by means of another auxiliary device, not shown, in order to adjust the work slide S1 on the guideway F1.
