Definitions

  • the present invention relates to a forming machine with at least one forming station with a stamp and a die as tools and a device for Adjusting the axial position of one of the two tools, as stated in the preamble of the independent claim 1 is defined.
  • the axial mutual position must be of the punch and the die during forming, which by adjusting the axial position of at least one the two tools can be achieved. Because the tools are exposed during the forming of large impact forces, must have the device for adjusting the axial position be formed stable accordingly.
  • So far adjustment devices are often used, which comprise a vertically displaceable adjusting wedge.
  • a forming machine each with such an adjustment per forming station is for example in US-A-4,898,017.

  • the adjusting wedge is a rotary wedge, which itself rotates at an adjustment, also rotates the contact surface on the body and is not longitudinally displaced. Thereby the force is applied to the body an adjustment of the adjusting wedge not changed significantly and is thus more optimal than in the previous forming machines.
  • the contact surface is circular and rotates upon rotation of the rotary wedge disk in place on Body.
  • a sprocket is arranged on the rotary wedge disk, over which this is rotatable. Due to the driving the rotary wedge disk via a ring gear on the periphery The contact surface and the inclined plane will not pass through Drive elements affected.
  • means for locking the rotary wedge disk available in every adjustable position. To this Way can be prevented by the during the Forming occurring large impact forces an unwanted Rotation of the rotary wedge disk is effected.
  • the angle of inclination is smaller than the limit angle for self-locking, whereby an unintentional shifting of the end face can be prevented on the inclined plane.
  • the pressure piece preferably comprises a face having the end face, rotatable turned part and thus over first Sliding surfaces associated, non-rotatable pressure part.
  • the first Sliding surfaces the shape of a convex respectively one Complementary concave spherical surface section.
  • this includes Rotary part an end face having the end face part and a related via second sliding surfaces, one of the first sliding surfaces exhibiting hinge part.
  • the second sliding surfaces have the shape a convex or a complementary concave Cylinder jacket or spherical surface section. If the second sliding surfaces the shape of spherical surface sections have, the rotary part at an adjustment of the rotary wedge disk not necessarily be rotated with respect to this.
  • the inventive forming machine means for rotating the rotary part or, if present, the hinge part coupled with the rotary wedge on, wherein these means preferably comprise a sprocket, the on Rotary part or if available is arranged on the hinge part. It is thereby ensured that the rotary part or the hinge part rotates together with the rotary wedge disk, whereby It can be ensured that the pressure piece not tilted, respectively that its correct end face plant obtained at the inclined plane of the rotary wedge disk remains.
  • the Pressure piece and the rotary wedge disk a through hole and / or an arcuate passage slot for a Ejector on.

  • the adjustment of the axial position is done by turning the rotary wedge disk 1 and the pressure piece 3, wherein the Rotary wedge disk 1 and the pressure piece 3 by the same angle be rotated so that the contact surface 11 of the rotary wedge disk 1 and the end surface 41 of the pressure piece 3 their orientation and do not change parallelism. Because both the rotary wedge disk 1 with respect to its axis of rotation 13 and the Pressure piece 3 with respect to its axis of rotation 42 through the arrangement should not be moved in the forming machine can, is at a rotation of the rotary wedge disk. 1 and the pressure piece 3, the end face 31 of the pressure piece. 3 relative to the rotary wedge disk 1 eccentric to the axis of rotation 13 postponed.
  • the Adjustment device traversing ejector 4 available for this, the pressure piece 3, a through hole 40 and the Rotary wedge disk 1 an arcuate passage slot 15th exhibit.
  • the pressure piece 3 Upon rotation of the rotary wedge disk 1 and the Pressure piece 3 remain the ejector 4 and the through hole 40 in place, while the arcuate through slot 15 shifts with respect to the ejector 4.
  • the arcuate passage slot 15 allows rotation up to 180 °.
