Definitions

  • the invention relates to a clinching device for non-positive and / or positive insertion of at least two sheet metal layers which overlap at least partially, with a joining die and an associated die, which is formed by a peripheral surface of a die wheel, wherein a transport device for performing the sheet metal layers by a Effective range of the clinching between joining die and die and in that the joining die is rotatable about a first axis of rotation, and the die rotatably disposed about at least a second axis of rotation, wherein the first axis of rotation and the second axis of rotation are arranged in the effective range of each other and transverse to the transport direction.
  • the invention also relates to a method for non-positive and / or positive insertion, wherein two layers of partially overlapping sheets are passed through a machining gap in a kneading region of a clinching between a joining die and an associated die at a transport speed in the transport direction, the punch in the die penetrates and the sheet metal layers deformed.
  • Punch-through devices are known in the art. These clinching devices include a plunger that fits into an associated die. It is always ensured that the joining punch does not hit the surface of the die.
  • the joining punch carries out a lifting and lowering movement in the clinching devices of the prior art. This lifting and lowering movement is linear. In the prior art, either the clinching device is moved along the at least two sheet metal layers, or the two sheet metal layers are moved along the clinching device. Nevertheless, until now only a discontinuous machining of the two sheet metal layers is possible.

  • the same shape can be used for each die wheel and / or the same machining steps can be used for each die wheel.
  • the costs in the production of the die are thereby minimized. Only one master mold is needed for the die wheel and / or one needs programming to edit the die.
  • the circumferential surfaces of the die wheels can be in contact with at least one surface of a layer of the sheets adjacent to the peripheral surfaces of the die wheels, it is advantageous if the die wheels are conical. The leadership of the sheets through the effective range is also improved.
  • each die wheel has its own axis of rotation, and the two axes of rotation lie inclined to one another in the same plane, it is possible effectively to prevent jamming of the metal sheets between the joining punch and the die, in particular the two die halves during machining. By then resulting better shaping of undercuts, firmer joints are achieved.
  • the second and third axes of rotation form an angle of about 150 ° to 170 °, preferably 160 °.
