Definitions

  • the invention relates to a method and an apparatus for the removal of arising during a punching process Slugs or the like Pieces of waste from one - especially as Hollow profile trained and perforated - workpiece that from one generated by a flowable active medium Internal high pressure is applied.
  • the slug must be disposed of safely.
  • punching from the inside out is the slug after punching in the Cutting die. This can be in the top or in the bottom Tool half to be arranged.
  • gravity can be disposed of used - or it has to be overcome.
  • the slugs are usually washed out of the Tool disposed of or by folding the slugs on the workpiece calmly. The flushing out does not result in one can check whether all slugs have been removed and the Process is extended. Folding the slugs does an assembly usually impossible with screws or rivets. In addition, the slug can tear off after assembly, it also increases the weight unnecessarily.
  • the inventor was aware of this state of the art set the goal of eliminating the identified disadvantages as well as the method described above and above all to improve the disposal options and a device to create for it.
  • the Forehead of the one also guided in that guide bore Hole punch from the die surface lying against the workpiece about the measure of that thickness of the workpiece against the Pressure direction of the active medium introduced into the workpiece and with it the slug at a distance from the die surface the workpiece are loosened, after which punch and slug in the opposite direction - ie after reducing the pressure and opening the Tool in the printing direction.
  • the slug In the former case, the slug is simply turned into an the profile cavity, in front of the die or the slug releasing fresh recess, driven catch device ejected through a punch; the slug gets into this fall arrester in free fall or - tub.
  • a suction device - if necessary supported by a nozzle - in front of the cutting die held, and the punch in the cutting die is brought up, whereby the expelled slug immediately is disposed of.
  • the slug disposal is optimized in the manner described.
  • the device according to the invention contains - preferably in each case can be used automatically - for the upper tool the in collecting tray entering the profile cavity.
  • a suction device is provided to the slug to highlight.
  • a - for example a wall section of a hollow profile 10, whose longitudinal axis is indicated at A - is a surface 12 a die 14 with a guide bore 16 for to recognize a cylindrical punch 18 with longitudinal axis B.
  • This workpiece 10 is in the context of a hydroforming process on his away from the punch 18 High pressure applied to surface 11.
  • FIG. 3 illustrates the complete material separation with increasing Distance of the punch 18 from the workpiece 10.
