Definitions

  • the invention relates to a band steel punching and creasing tool for the arrangement between a pressure plate and a counter-punching plate of a punching machine with a carrier plate, in which slots are provided over its thickness, with knives and / or creasing lines made of band steel arranged in the slots and hardened with their Cutting or their creasing ends protrude from the carrier plate on their side facing the counter-punching plate, with an intermediate plate made of metal arranged on the side of the carrier plate facing the pressure plate, against which the knives or creasing lines rest with their backs and with one on that of the pressure plate facing side of the intermediate plate made of metal intermediate layer.
  • the invention further relates to a method for dressing such a steel band punching and creasing tool, in which an intermediate plate carrying a metal intermediate plate is attached to the top of the carrier plate, a cardboard box is placed on the counter-punching plate and during dressing the carrier plate by means of the pressure plate so far in the direction the counter punch plate is moved until the All knives touch the counter-punching plate or the crease lines sit on the cardboard while their backs are supported on the intermediate plate.
  • the backs of the knives are also designed as hardened cutting edges.
  • a plate is attached to the top of the carrier plate, which consists of a metal that is softer than the hardness of the cutting edge. If the cutting edge of a knife protruding on the underside of the carrier plate hits the counter-punching plate when the carrier plate is lowered, the hardened cutting edge of the back of the knife penetrates into the intermediate plate as the carrier plate moves further downward. For the preparation, the carrier plate is moved down until all knife edges protruding from the underside of the carrier plate are loaded evenly.
  • EP-A-0 297 324 A1 discloses a band steel punching tool of the generic type, on the support plate of which is arranged one above the other toward the pressure plate, a thin iron plate, an intermediate layer made of a paper web and a further plate on the back.
  • the thickness of the back of the knife is reduced compared to the thickness of the knife, the back sections of reduced thickness being cut over the length of the knife and being bent out to the opposite edges of the slots in the carrier plate.
  • the backs are pressed into the metal plate.
  • the invention has for its object to design the generic steel strip punching and creasing tool so that it can be prepared in a punching machine in a short time without affecting the punching performance of the punching machine.
  • the intermediate plate made of metal has a thickness of 0.8 to 1.5 mm, a 0.2-stretch limit R p0.2 of 20 to 90 N / mm2, a Tensile strength R m from 65 to 150 N / mm2 and an elongation at break ⁇ from 3% to 35%, that the intermediate layer before dressing is an elastomer plate with a hardness of 60 to 100 Shore A hardness and a thickness of 0.5 to 1.5 mm and that the intermediate layer after dressing is a correspondingly thick metal plate which is arranged instead of the elastomer plate.
  • an intermediate plate made of metal with a thickness of 0.8 to 1.5 mm, with a 0.2 proof stress R p0.2 of 20 to 90 N / mm2, one Tensile strength R m of 65 to 150 N / mm2 and an elongation at break ⁇ of 3% to 35% is used that on the intermediate plate as an intermediate layer an elastomer plate with a thickness of 0.5 to 1.5 mm and a hardness of 60 to 100 Shore A hardness is set and that after dressing the elastomer plate is replaced by a correspondingly thick metal plate.
  • the intermediate plate expediently consists of aluminum or copper.
  • the intermediate plate advantageously consists of one of the following alloys: AlMgSi, AlMg, AlCuMg, AlMn, AlMgMn.
  • the backs of the knives or the crease lines are preferably rounded.
  • the elastomer plate is replaced by a metal plate as a protective plate in order to ensure an optimal transfer of the pressure force of the pressure plate to the carrier plate.
  • the strip steel punching and creasing tool 15 shown in FIGS. 1 and 2 is arranged between a pressure plate 12 and a counter-punching plate 14 of a punching machine 10.
  • the band steel punching and creasing tool 15 consists of a horizontally arranged in the punching machine 10 support plate 16 made of wood laminate, which has vertical slots 18 for receiving punching knives 20a, 20b for punching and creasing lines 20c for creasing, which consist of band steel.
  • the slots 18 extend from the bottom to the top of the carrier plate 16.
  • a 1 mm thick intermediate plate 26 is attached, which consists of pure aluminum 99.5 G9.
  • This material has a 0.2-elongation limit of 60 N / mm2, a tensile strength R m of 90 N / mm2 and an elongation at break ⁇ A5 of 13%.
  • a 1 mm thick elastomer plate 28 with a hardness of 85 SH (A) is attached to this intermediate plate 26.
  • the knives 20a, 20b, or the creasing lines 20c are received in the slots 18 of the carrier plate 16 such that their back 24 faces the intermediate plate 26.
  • the knives 20a, 20b and the creasing lines 20c have an essentially constant thickness except for the area of the cutting edge 22, ie they have the same thickness in the area of the back 24 as on their shaft 23. In the area of the upper corners, the back 24 is rounded .
  • the hardness of the back 24 is equal to that of the shaft.
  • the knives 20a, 20b and the creasing lines 20c are inserted into the slots 18 of the carrier plate 16 such that their backs 24, as shown in FIG. 1, on the intermediate plate 26 concerns.
  • a cardboard box 30 is arranged on the counter-punching plate 14. Then, with the punching machine 10, a few dressing strokes are carried out in order to adjust the knives 20a, 20b so that their cutting edges 22 simultaneously cut through the cardboard 30 during the punching process and, under the same pressure, touch the surface of the counter-punching plate 14, so as to local unevenness of the surface of the counter-punching plate 14, which are exaggerated in FIGS.
  • the pressure plate 12 is moved together with the band steel punching and creasing tool 15 towards the counter-punching plate 14. If the knife 20a strikes the counter-punching plate 14 with its cutting edge 22, its knife back 24 penetrates into the intermediate plate 26 during a further movement towards the counter-punching plate 14.
  • the band steel punching and creasing tool 15 is moved downward during the dressing strokes until the cutting edges 22 of all the band steel punching knives 20a, 20b touch the surface of the counter-punching tool 14 in such a way that the cardboard 30 is properly severed across the entire cut surface. This position is shown in Fig. 2.
  • the creasing lines 20c are prepared analogously, except that the lower ends of the creasing lines 20c are seated on the cardboard 30 instead of severing it.
  • the back 24 displaces the ductile material of the intermediate plate 26 in the direction of the elastomer plate 28.
  • the material can thereby escape into the elastomer plate 28, so that the sensitive knife edge 22 or the lower end of the line does not damage undergoes a plastic deformation during power transmission during height compensation.
  • the width of the back 24 and the rounding of its corners prevent the material of the intermediate plate 26 from tearing.
  • the elastomer plate 28 is replaced by an equally thick metal plate for normal operation.
  • This metal plate can be the protective sheet that is customary in such punching machines 10 or a comparable plate of a hardenable Al alloy.
