Definitions

  • the invention relates to a device for punching, embossing and / or forming flat elements with a base body with table and support for the flat element and with a tool base bearing a base plate, which by means of a drive for performing the processing operation on the support out in a processing station for the engagement of the tool punch with the support and away from the support is movable away.
  • Such devices are used to punch or deform flat semi-finished products, such as plates, strips and blanks in a continuous process.
  • These webs, bands, plates or blanks, which are referred to as flat elements can be made of different materials, for example cardboard, laminated board material, multilayer material, sheet metal.
  • Previously known devices similar to the type mentioned above are provided with a direct hydraulic or pneumatic drive with a cylinder acting on a punching tool.
  • the full punching force must be applied in the punching direction, resulting in a jerky or jerky force curve and only low clock speeds can be achieved because the withdrawal of the cylinder acts as Vertustzeit.
  • DE-U-1 974 429 discloses a device according to the preamble of patent claim 1.
  • the object of the invention is therefore to provide a device of the type mentioned above, with a large number of very short, high-precision punching strokes in succession for the introduction of punched holes or embossments are possible.
  • a fast moving flat elements while short downtime and thus short cycle times, even possible small processing strokes to be achieved.
  • the invention is based on the basic idea to drive the attached to the base plate tool punch according to a certain movement pattern. It is about the movement ultimately of the tool punch on the support or away from this, which holds the flat element. In the case of punching, a hole may be provided in the post so that the tool post pierces through the flat element into that hole of the post.
  • the movement pattern itself should follow the principle of moving the tool punch (and thus the base plate) toward and away from the processing position without significant pressure build-up, in which case a greater movement speed is provided.
  • the movement should take place only for a short distance, but to generate a high pressure.
  • This movement pattern is achieved via an intermediate rotary lever between the drive and the base plate.
  • the tool stamp will be beneficial over the whole Depth of cut or embossing depth away during this processing always kept absolutely parallel to the plane of the flat element. Such a construction is robust and precise.
  • this advantageously achieves a flat, gentle, sliding and non-jerky course of force.
  • those shocks that occur in conventional devices when the full punching force is applied in a linear direction can be avoided.
  • the invention provides that the axis of the drive is perpendicular to the axis of the tool punch.
  • the drive can be a pressure transducer with a cylinder and a piston whose piston movement in one embodiment runs parallel to the conveying direction of the flat element. Since the axis of the tool punch is arranged perpendicular to the plane of the flat element, then the drive axis is perpendicular to the axis of the tool punch.
  • the drive is a motor whose axis of rotation is parallel to that of the tool punch; in a particular embodiment, the axes even collapse.
  • axis of the drive is perpendicular to the axis of the tool punch
  • the linear direction of movement of the base plate is determined by acting between the base body and the base plate column guide and that the drive in its lying perpendicular to it Has axis (of the drive) linearly oscillating drive means.
  • Such an oscillating drive means may be, for example, a reciprocating piston type pneumatic or hydraulic cylinder.
  • the piston rod can be considered as such a linear, oscillating drive means by which one can think of the axis of the drive. Perpendicular to then again runs the axis of the tool punch.
  • the column guide allows precise angular posture and precise machining, for example punching or stamping.
  • the long rotary lever is pivotable about a fixed to the base pivot point and coupled at one end via a toggle joint with one end of a short pivot lever, the other end is coupled via a toggle lever bearing with the base plate.
  • This mechanical structure provides a dead center in a certain position of the long rotary lever and the short pivot lever, and this results in consideration of the above basic idea greatest force effects in the vicinity of this dead center.
  • this is achieved by the long path of the linearly oscillating drive means with the advantage of a short path of the machining tool, for example tool punch.
  • the drive may comprise a pneumatic cylinder or a hydraulic cylinder.
  • the long rotary lever, coupled with the short pivot lever can be regarded as a kinematic system, which acts so that the base plate both in the direction of rotation of the long rotary lever counterclockwise and in the clockwise direction of rotation one machining operation, for example a Punching process is performed.
  • the principle according to the invention can be realized clearly, namely that first with large and fast stroke and low force of the tool punch brought close to the flat element and then made with a short path and great power processing; which in turn, with a large and fast stroke and low force, the tool punch is removed from the flat element or moved away.
  • the flat element as a moving material strip, wherein processing of this strip in a continuous process can be carried out in an economical and very precise manner. This is achieved with the measures according to the invention by the very short downtime and the equally short machining operation with a small stroke.
  • the new device allows extremely short cycle times and the processing of ribbons or webs as flat semi-finished products when passing through. This also applies to very fast moving belts and trains.
  • FIGS. 1 to 3 The one device for punching a horizontally continuous metal strip is shown in FIGS. 1 to 3.
  • a holder 2 for a cylinder pivot bearing 3 On a base body 1 of the punching device, a holder 2 for a cylinder pivot bearing 3 is attached.
  • a piston rod 5 is mounted linearly movable so that at the free end of the piston rod 5, a clevis 6 is mounted, depending on the control of the pneumatic cylinder 4 in the outward direction 7 (arrow) or the inward direction 8 (arrow ) is movable.
  • a long rotary lever 9 is pivotally connected to the upper bearing 10 of the rotary lever 9. The long rotary lever 9 can be pivoted about its fixed to the base 1 pivot point 11 by means of the drive 4, 5. For this pivoting is located in the base body 1, a recess 12th
  • this has a toggle joint 13, to which a short pivot lever 14 is articulated.
  • the latter is rotatably connected via its lower, provided at the other end of the pivot lever 14 toggle bearing 15 with a holder 16 which is fixedly attached to a base plate 17.
  • this base plate 17 is horizontal, so is at a distance and parallel to a table 18 which is also attached to the base body 1. While the latter is stationary, the base plate 17 can be moved translationally upwards in the upward direction 19 and the downward direction 20. This movement is performed by the drive with the pneumatic cylinder 4 and the piston rod 5. So that the base plate 17 remains parallel to the horizontal plane of the table, a column guide 21 is provided, the structure of the figures 1 to 3 is clearly visible and need not be described further here, because a column guide is known per se and not the subject of this invention , While the holder 16 is mounted on the upper side of the base plate 17, is located on the opposite lower side of a holding part 22 for a resiliently biased by a compression spring 23 tool punch 24.
  • the tool punch 24 is thus in the upward direction 19 and downward direction 20th relative to the base plate 17 movable.
  • the longitudinal center axis of the tool punch 24 lies in the same direction and is designated as the axis 25 of the tool punch 24.
  • this axis are also in this embodiment, the toggle lever bearing 15 and the pivot point 11. This results in the possibility of a toggle lever dynamics, as will be described with reference to Figures 2 and 3.
  • a plate-like support 26 is fixed, in the middle of a hole 27 is mounted with ground upper edges 28, whose dimension is matched with precision to the outer edge of the tool punch 24 in a conventional manner. Only schematically, the metal strip 29 is indicated on the support 26, which lies between the support 26 and the tool punch 24.
  • the machining is in the case of the embodiment of Figure 2 is a punching, and here the punched hole disc 30 is shown schematically. If the piston rod 5 is further moved in the outward direction 7, the long rotary lever 9 continues to rotate about its pivot point 11 in the counterclockwise direction and enters the position III of Figure 3. As a result, the base plate 17 was moved back up out of the support 26. With a reciprocating stroke of the piston rod 5 two punching operations can be performed.
