Definitions

  • the invention relates to a device and a method for metal forming Joining parts. Forming technology joining processes and corresponding devices used to join parts together, for example in machines or vehicles, but can also be used in other applications.
  • the joining of parts made of different materials by forming has one a very long tradition that can be traced back to metal extraction and processing can.
  • Methods in which the joining parts or auxiliary joining parts to be connected locally or sometimes completely reshaped are assigned to the group “joining by reshaping".
  • Sub-groups of the manufacturing process "joining by forming” are the manufacturing processes today Joining by forming wire-shaped bodies, joining by riveting as well the joining known by forming sheet metal, pipe and profile parts.
  • a push-through joint does not only have the favorable properties of positive locking with regard to the transmission of large forces, but also one due to the adhesion caused freedom of play in the connection.
  • Crucial for safe and secure Reproducible push-through joints are, on the one hand, the choice of a suitable tool set depending on the material used and the part geometry, on the other hand the perfect holding and loosening of the positioned parts to be joined by suitable Hold-down and wiper systems.
  • the load-bearing behavior of a clinching connection depends apart from the surface quality of the parts to be joined, primarily the geometry of the joining element, its geometric position relative to the direction of loading and of Type of load.
  • punctiform clinching connections are relatively expensive to buy Manufacture, because with a single tool set for a joining point, only parts to be joined can be attached to each other in this single point during a work cycle, the tools being of high specific during the setting of the clinch joint Exposed to stress.
  • the one with the punctiform clinching connections provided components are also not gas or water tight.
  • the parts to be fastened together are placed on top of one another in a desired position, at least one stamp wheel suitably shaped on the circumference with a rotating movement cuts a groove in the parts to be fastened together in a line and / or countersinks, and at least one second die wheel suitably shaped on the circumference with a rotating movement, the parts to be joined at least in the joining area Connection forms.
  • the chronological order of the individual production sub-steps is in As a rule, real processes are not clearly separated from one another, but go into one another over or expire at the same time. However, it is also conceivable to schedule the processing steps to perform staggered, for which purpose suitably shaped counterholders are required.
  • a linear tool structure is used provided stamp and die in their starting position adjacent to each other stored, then moved towards each other by a lifting movement, thereby bringing with her line-shaped tool structure a line-shaped joining connection into each other fastening parts, and stamp and die are made after making a line Joint connection moved away from each other again by a return stroke movement.
  • a device according to the invention in accordance with an embodiment of the invention for forming Joining parts consists of a frame, at least one in the frame rotatably mounted, on the circumference suitable for cutting and / or countersinking a groove shaped stamp wheel, at least one rotatably mounted in the frame, on the circumferential side Upset of parts suitably shaped die wheel, the punch and die wheels so arranged in the frame relative to each other that superimposed parts under conveyable to them or above them and / or the stamp and die wheels above or below the joining parts can be moved away.
  • the punch and die have a tool contour with a linear course of the effective surfaces.
  • the proposed invention enables linear joint connections instead to produce the previously known point-shaped joint connections.
  • the clinching connections those according to the inventive method or a corresponding one Device are manufactured, have a high rigidity. Also the tension distribution more even in the joining zone.
  • Instead of multiple strokes for manufacturing a permanent connection of parts can now be joined parts during a single conveying or Lifting movement with a tool set over a distance by means of a clinching connection be connected to each other.
  • the tools are more even loads, which has a positive effect on their costs and service life, and depending on the geometries of the parts to be joined and the line-shaped clinching connection, the connection can be gas or be made waterproof.
  • the joining parts 2 and 4 can be seen, which are interconnected by a clinching connection 6 should be connected.

  • the stamp wheel 8 and the die wheel 10 rotate in the opposite direction, so that either the joining parts 2, 4 between them can promote or guided along the joining parts 2, 4 by a movable frame become.
  • the punch wheel 8 is formed on the circumference so that a bead 12 has a groove 14 in the Join parts 2, 4 can press.
  • the Stamp wheel 8 are arranged so that at least the bead 12 with its outermost Circumferential surface is located below the surface of the overlying joining part 2.
  • the punch wheel 8 is guided so deep that the bead 12 is at its lowest point below the normal plane of both joining parts 2, 4. If the joining parts 2, 4 then under the Stamp wheel 8 along or this over the joining parts 2, 4, so one presses Groove 14 in the joining parts 2, 4 if they are adequately supported.
  • the arrangement of the Bead 12 below the surface of the overlying joining part 2 can either from the start with the position of the support and the material thickness of the joining parts 2, 4 by a fixed appropriate storage of the stamp and die wheels can be coordinated, or the stamp wheel 8, the matrix wheel 10 and / or the supports are adjustable in their spatial arrangement arranged so that the bead 12 is movable into a position in which this with his circumferential outermost surface is below the surface of the upper joining part 2.

An effect similar to that described above can also be achieved if alternative or in addition, the joining parts 2, 4 can be changed in their conveying direction or spatial position are led.
  • the compression of the material is in the area of the clinching connection important.
  • a force and force is created by spreading or extrusion positive-locking connection.
  • the compression is caused by the pressure with which the die wheel 10 acts on the joining parts 2, 4, and a counter pressure, which the stamping wheel 8 advantageously generates, causes.
  • the circumferential geometry of the die wheel 10 should be designed so that it expanding or extruding the material of the joining parts 2, 4 advantageously supports.
  • the compression is important regardless of whether the process is continuous or takes place under the effect of several tool parts arranged one after the other. in the latter case is called a multi-stage process. Then for each process step Tool set with the appropriate geometry should be available, simply one after the other to be ordered. If a linear groove 14 has already been produced, not all of them have to subsequent tool parts work linearly-continuously, but it can depend on technical requirements for the strength of the connection also selective or stroke-controlled tools to be involved in establishing a clinching connection. It is also possible that the punch and / or die wheels 8, 10 with or without cutting portion work. In the subsequent process stages, the joining line can be leveled by one to get a survey-free connection.
