Definitions

  • the invention relates to a band steel punching tool for blanks made of cardboard or the like, in particular folding box blanks, with at least one band steel punching knife inserted into a slot of a carrier plate and protruding therefrom with a hardened cutting edge, the back of which faces an intermediate plate and a hardened pressure plate.
  • Such steel strip tools are attached to the upper table of a punch and work against a plane-parallel counter-punching plate on the lower table of the punch.
  • the so-called strip steel punching lines have the same height, so that the material to be punched, which rests flatly on the counter-cutting plate, is cut through uniformly on all cutting edges, because otherwise the cut-outs will break free the sheet material is not possible.
  • the present invention has for its object to provide a band steel punching tool, with the help of which flawless cuts can be made without additional adjustment work, even if the band steel punching tool is used repeatedly.
  • the band steel punching tool according to the invention which initially does not yet have a height adjustment, is used for punching, the cutting edges or cutting edge areas which protrude furthest from the carrier plate first strike the material to be punched or the counter-cutting plate, as a result of which increased pressure forces occur on these cutting edges or cutting edge areas.
  • This condition which corresponds to a uniform altitude, can be brought about already during the first trial cuts without the need for special height adjustment work. The desired same altitude thus occurs automatically in the interaction of the rear cutting edges with the softer intermediate plate.
  • the punching tool according to the invention can be used repeatedly, it being only necessary to ensure that the rear cutting edges of the band steel punching knives face new areas of the intermediate plate. This can be achieved by slightly moving the intermediate plate in the x and y directions. In addition, the intermediate plate can also be turned over, as a result of which the intermediate plate can also be used repeatedly. Even if a new intermediate plate is used each time the strip steel punching tool in question is set up again, the effort involved is low because the intermediate plate has only a small share in the total cost of the strip steel punching tool.
  • the intermediate plate Since the above-mentioned height tolerances are only a few tenths of a millimeter even when all tolerances are unfavorably added, it is sufficient if the intermediate plate is made thin and single-layered. Their thickness should be a little larger than the expected maximum tolerance sum in order to avoid cutting through the intermediate plate at the indentation points of the rear cutting edges as far as possible. Accordingly, a few tenths of a millimeter are sufficient for the thickness of the intermediate plate. Good experiences have been achieved, for example, with a 0.3 mm thick intermediate plate.
  • the intermediate plate consists of a notched impact-resistant material, the Rockwell hardness of which is approximately up to 50% of the Rockwell hardness of the hardened cutting edges of the band steel punching knife.
  • the Rockwell hardness of the hardened cutting edges of the band steel punching knives is usually about 50. Accordingly, the lower Rockwell hardness of the intermediate plate should be between 40 and 25.
  • the Rockwell hardness of the material of the intermediate plate can even be below 25, because, for example, in the case of a wedge-shaped cutting edge shape, the penetration resistance increases in accordance with the increasing surface area of the penetrating cutting edge regions.
  • the intermediate plate expediently consists of a metal which is softer than the hardness of the cutting edge. But plastics can also be used as an intermediate plate, for example polytetrafluoroethylene.
  • the rear cutting edge of the band steel punching knife can have different designs within the scope of the inventive concept. It can, for example, be identical to the front cutting edge which brings about the punching cut, as a result of which the production of the band steel punching knife is made considerably easier.
  • the arrangement can advantageously also be such that the back of the band steel punching knife is shaped by hollow grinding to form a hardened double cutting edge.
  • the back of the band steel knife can also be designed as a hardened sawtooth blade.
  • one can A cutting edge is created which is composed of short individual cutting edges arranged at a distance from one another (e.g.
  • the intermediate plate material can have a greater hardness than in the case of a continuous rear cutting edge.
  • the arrangement can be made in a band steel punching tool with an additional at least one recessed in a slot of the carrier plate less than the band steel punch knife protruding from the support plate band steel folding ruler so that the back of the band steel folding ruler is designed as a hardened cutting edge.
  • the band steel folding rulers also automatically adjust themselves to the same height after the band steel punching knives, by pressing the rear cutting edges of the band steel folding rulers more or less deeply into the intermediate plate in accordance with the existing height tolerances during the punching and folding process.
  • the band steel punching tool is shown on a scale which is considerably larger than the reality, while in FIGS. 4 and 5 only the thickness of the band steel punching knife is exaggerated for clarity.
  • the band steel punching tool shown in FIG. 1 shows two band steel punching knives 1 and a band steel folding ruler 2 located between them, each inserted into slots 3 and 4 of the carrier plate 5, which is usually made of plywood.
  • the band steel punching knives 1 projecting downward from the carrier plate 5 each have a wedge-shaped, hardened surface Cutting edge 6, which is used with a counter-punching plate for punching a sheet-like material to be placed on the counter-punching plate 7, e.g. B. cardboard works together.
  • the band steel folding ruler 2 is rounded off at its outer end 8 in order to produce a fold or groove line and projects less downward than the cutting edges 6 from the carrier plate.
  • a hardened pressure plate 9 is assigned to the band steel punching tool, on which it is supported.
  • a thin single-layer intermediate plate 10 is located between the pressure plate 9 and the carrier plate 5.
  • the band steel punching knives 1 and, if present, the band steel folding rulers 2 are also formed on their backs as wedge-shaped, hardened cutting edges 11 and 12, which bear against the facing surface of the intermediate plate 10 before the first punching or embossing process.
  • the intermediate plate 10 consists of a material which has a lower hardness than the cutting edges 11, 12 facing the intermediate plate 10.
  • the cutting edges 11, 12 can penetrate into the intermediate plate 10 in order to compensate for height tolerances, as is shown in FIG.
  • the band steel punching knife 13 shown in FIG. 3 has a hollow ground groove 14 on its back, which creates a double cutting edge, the two cutting edges 15 of which are at the same height.
  • the rear cutting edge of a band steel punching knife 16 is designed as a saw tooth cutting edge 17 consisting of individual saw teeth 18.
  • the band steel punching knife 19 is also equipped with a rear sawtooth blade 20, the saw teeth 21 of which are triangular.
  • the rear cutting edges 17 and 20 of the intermediate plate lie with a considerable reduced contact surface, whereby surface pressures of considerable size occur during the automatic height compensation, which facilitate the penetration of the teeth 18 or 21 into the material of the intermediate plate 10.
  • the hardness of the intermediate plate 10 can be chosen larger than in the embodiment according to FIGS. 1 and 2, but the hardness of the intermediate plate 10 always remains below the hardness of the cutting edges 17 and 20, respectively.
