Definitions

  • the invention relates to an automatic punching machine with a carriage movable at right angles in the horizontal X and Y directions and a punching tool of a punching cylinder of a punching head fixed to it, movable in the vertical Z direction, for processing a multi-contact plug with different contact assignments according to the preamble of the first protection claim.
  • a device for breaking out and removing waste punched parts from panels or sheets of material, in particular for flat bed punching and / or embossing machines, is known, DE 196 48 952 C1, which has a plurality of breaking needles which are arranged at precisely predetermined positions on the punching tool.
  • a disadvantage of such a device is that separate punching tools or matrices with differently arranged stripping needles have to be kept available to vary the workpiece, which is very uneconomical and requires an interruption of operation to convert the punching tools if a variation is desired.
  • the object of the invention is to provide an automatic punching machine which can work without such an interruption and can thereby process a large number of different workpieces without the production having to be interrupted and the automatic punching machine converted.
  • the punch needle has a cross-sectional shape that corresponds to the ejection cross-section of a cavity of a multi-contact plug, so that the punch needle can punch out the pins closing the cavities one after the other at the required locations of the multi-contact plug, this embodiment of the invention very much to realize precise discharge cross-sections that have dimensional tolerances of only a few 1/100 mm.
  • the punch needle is preferably mounted in a punch piston which is equipped with a vertically extending recess, such as a through recess in the form of an elongated hole, with at least one vertically extending inner wall.
  • a horizontal eccentric pin corresponding to the inner wall of the recess and having a radial eccentric surface is rotatably mounted about its horizontal axis, which extends into or through the recess, with its eccentric surface being designed such that it can be placed against the inner wall of the recess to allow rotation of the Punching needle to completely exclude its vertical axis and to be able to provide the required precision.
  • the automatic punching machine is equipped with at least one further punching head with a separate punching cylinder for each further punching tool, so that the punching machine is equipped with punching needles of different cross-sections as punching tools that can be alternately put into operation or out of operation, so that a multi-contact plug with several different cavity cross-sections can also be processed without interruption.
  • At least one blow-out nozzle pointing downwards in the punching direction or a ring nozzle, with which an air curtain can be generated around the punching needle, which safely transports the punched-out pins out of the workpiece so that they cannot hinder the production process.
  • the punching piston of the automatic punching machine can optionally be pneumatic, hydraulic or with other fluid technologies, e.g. be driven with water, or mechanically or by means of a linear drive, so that it can be used universally.
  • FIG. 2 shows a side view of the assembled punching machine according to FIG. 1,
  • FIGS. 1 and 2 are front views of the automatic punching machine according to FIGS. 1 and 2,
  • FIG. 5 shows a section through a punching head at right angles to FIG.
  • FIG. 6 shows a section through a punching head according to FIG. 4 with the punching tool extended
  • the automatic punching machine consists of an XY drive unit 9 with a carriage 1 movable in the X direction and a carriage 2 movable in the Y direction, as well as a punching head 5 with a punching cylinder 4 arranged on it, in which a punching piston 1 1 is vertically movably guided, in which, in turn, a punch needle 7 is easily exchangeable at its front end.
  • the automatic punching machine can be equipped with a placeholder 18 for a second punching head.
  • the punching piston 1 1 has a vertical recess 12, which is designed here as a through hole and has inner walls 13 parallel to one another, an eccentric pin 14 extending horizontally through the punching cylinder 4, which also passes through the recess 12 in the punching piston 1 1, with its radial Eccentric surface can be placed at least on an inner wall 13 of the punching piston 1 1, whereby a rotation of the punching piston 1 1 about its vertical axis is prevented.
  • an air ring 1 7 is arranged around the punching piston 1 1, which has blow-out nozzles 15 in vertical directions downwards or also an annular nozzle that generates an air jacket around the punching needle 7 so that it is ensured that punched-out pins 16 of the multi-contact plug 6 to be produced are securely driven out in the punching direction and clear the corresponding cavities 10.
  • a punch needle 7 has exactly the cross section of such a cavity 10, so that highly precise ejection cross sections with a tolerance of only a few 1/100 mm can be produced.

Abstract

La présente invention concerne un automate de poinçonnage, qui est équipé de chariots (1 ; 2) mobiles perpendiculairement l'un à l'autre dans des directions horizontales X et Y, et d'un outil de poinçonnage (3), fixé aux chariots, mobile dans une direction verticale Z, d'un vérin de poinçonnage (4) d'une tête de poinçonnage (5) pour l'usinage d'un connecteur à multiples contacts (6) ayant différentes implantations de contacts, qui peut travailler sans interruption et, par conséquent, peut usiner une pluralité de différentes pièces à usiner sans que la production soit interrompue pour cela et sans que l'automate de poinçonnage doive être modifié, ce qui est obtenu du fait que l'outil de poinçonnage (3) se compose d'une seule aiguille de poinçonnage (7).
