Definitions

  • the invention relates to a holding device for punching knives on a punching machine, in particular trolley punch or bridge plate punch, in which the pressure foot with the punching knife attached to it can be rotated.
  • the punching knives of a punching machine are usually screwed onto a support plate and, depending on the design, these are either inserted into angle rails or dovetail rails on the punching head which carries out the punching movement.
  • the punching knife must have a precisely defined position to the center of the pressure foot of the punching head, especially in the case of programmed punching. If a punch knife is used on a so-called cart beam punch or bridge plate punch, in which the pressure foot is also rotated, the punch knife must be mounted exactly in the center of the axis of rotation. The exact central or central position of the punching knife is difficult to set up in conventional punching machines.
  • the object of the present invention is to propose a holding device for punching knives of the generic type in which a simple central or central arrangement of the punching knife is possible.
  • a magnetic chuck is attached to the pressure foot, which has at least two ledges or grooves on the contact surface facing the punching knife, which or their imaginary extensions intersect in the central axis or axis of rotation of the pressure foot, the respective punch knife on its contact surface facing the magnetic chuck has grooves or pins matching the strips or grooves.
  • the punching knife can be fixed in the middle or center of the pressure foot at any time. Due to the fact that the magnetic clamping plate has strips or grooves which cross each other in the central axis or axis of rotation and over or into which corresponding grooves or pins can engage when the punching knife is mounted, an inevitable centering is achieved. Other combinations of protrusions and recesses can also be used.
  • the strips or grooves on the magnetic chuck preferably run perpendicular to one another.
  • the strips or grooves on the magnetic chuck are spaced apart from the central axis or axis of rotation of the pressure foot and extend to the outer edge of the magnetic chuck. In this way, the strips or grooves are only provided where they are required for centering the attached cutting knife, without the risk that the cutting knife will rotate relative to the magnetic chuck.
  • the punching head of FIG. 1 which is intended, for example, for a bridge plate punch, not shown, has a magnetic chuck 1 which is screwed onto a pressure foot 2 of the punching head.
  • the function of such a bridge plate punch results, for example, from DE-A-2 827 138.
  • Bars 3 are provided on the lower contact surface of the magnetic chuck 1, which crosswise with respect to the central axis or the axis of rotation of the pressure foot 2, as is evident from Fig. 2 shows to run at right angles to each other.
  • four strips 3 are provided, which end in front of the central axis or axis of rotation of the pressure foot 2 and extend to the outer edge of the magnetic chuck 1, as can be seen in particular from FIG. 2.
  • the punching knives 4, 5 can be attached to the magnetic chuck 1 centrally or in a predetermined position.
