Definitions

  • the invention relates to a method for trimming tools of a flatbed sheet punching and / or embossing machine having the features of claim 1 and to a method for surface correction of crucibles of flatbed sheet punching and / or embossing machines according to claim 11.
  • punching As punching the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds. Also the practices practiced in print finishing, such as punching with punch, corner punching and register punching are counted to this area.
  • the punching takes place against a punching pad or against stamp, in some cases it is also shearing operations.
  • Packaging materials made of paper, cardboard, cardboard or corrugated board are mainly punched in sheet format. Even materials such as film (in-mold), various thin plastics or aluminum foil can be processed accordingly. When punching but also creasing lines or blind embossing can be introduced into the benefit. This complex process makes it indispensable to punch the sheets individually.
  • Such a flat bed punch is for example from the DE 30 44 083 A1 known.
  • the two tables are equipped with cutting and scoring tools or corresponding counter tools with which punched out of the cyclically guided between the table surface sheets the benefits and at the same time pressed the necessary for clean folding grooves. In the subsequent breakout the waste is removed by machine tools. Depending on the equipment of the machine finally the punched benefits can be separated in a designatedWhentrenn arthritis.
  • the punching pressure in the sheet punching and embossing machine must be adjustable according to the sheet being processed.
  • punching force adjusting devices can only be adjusted globally, i. based on the entire surface of the crucible. Due to the design, however, an uneven punching force distribution over the surface of the crucible is present in all stamping and embossing machines according to the prior art.
  • the punching force is introduced via individual force introduction points and thus does not affect the entire crucible surface.
  • there is a deformation of upper and lower table which in turn results in an uneven punching pressure distribution over the surface of the crucible.
  • height differences of the punching or Rillmesser, as well as the wear of the knife cause an uneven punching pressure distribution.
  • the uneven punching pressure in turn causes an unclean cutting of the cutting blade of the punching tool.
  • the DE 35 31 114 A1 describes a method and a device for pressurizing a press for producing embossing tools.
  • the press is operated separately and independently of a sheet punching and / or embossing machine.
  • the press has a large number of hydraulic pistons which carry a pressure plate.
  • the pressure plate serves to emboss the tools.
  • the pistons can be electrically controlled via a control panel, whereby the pressure build-up on the pressure plate can be varied precisely and specifically.
  • the DE 39 07 826 B2 describes an apparatus for producing stamping tooling, namely an impression machine.
  • an impression machine In order to be able to relocate the punching tool preparation into the impression machine, in a first step the topography of the pots of the punching machine is detected. The topography of the crucible is then simulated in the impression machine below. This will allows the punching tools can be dressed in the impression machine and the punching machine can continue to operate during this trimming. The effort for trimming the punching tools is not reduced thereby.
  • Such a sensor is for example in the DE 690 11 672 T2 described.
  • Such piezorestrictive pressure sensors have lattice-shaped electrode networks arranged parallel to one another. Between the electrode nets is a layer of pressure-sensitive resistor material, for example of silicon, which reacts to pressure similar to a strain gauge. The pressure on the sensor causes a change in length of the resistance material and thus a change in its resistance. By applying a voltage to the electrode networks, the resistance value of the resistance material can be determined over its area.
  • a method for trimming a punching tool is also known from the patent specification EP 0798 086 A1 ,
  • a punching tool is aligned as in a variant of the method by means of a backing trimming sheet.
  • the object of the present invention is to describe a method for trimming tools of a flatbed sheet punching and / or embossing machine, which reduces the set-up time and thus increases the productivity of the machine. Another object is to describe a method which further reduces set-up time.
  • the inventive method is used for trimming tools, in particular stamping and embossing tools, a Flachbettbogenstanz- and / or - embossing machine.
  • a Flachbettbogenstanz- and / or - embossing machine has at least one punching and / or embossing station with an upper and a lower crucible.
  • it is a flatbed sheet punching machine with a punching and hot foil stamping station.
  • a measurement of the pressure distribution in the at least one punching and / or stamping station by means of a sheet-like, in particular film-shaped pressure distribution sensor.
  • a neediness distribution is calculated based on the previously determined pressure distribution.
  • the need for dressing usually indicates the need for dressing in ⁇ m, which is necessary for a uniform theoretical pressure distribution and thus a clean punching and embossing.
  • the trimming of the tool is carried out according to the previously calculated demand for despatching.
  • the trimming of the tools is advantageously accelerated considerably, since the trimming needs distribution is determined in one step and does not have to be determined iteratively by repeated punching or embossing and evaluation of the punching or embossing result, as usual.
  • the area-shaped pressure distribution sensor is removed again after measuring the pressure distribution from the punching and / or embossing station. This ensures that the pressure distribution sensor is only loaded during the measurement, but not during the regular operation of the flatbed sheet punching and / or embossing machine.
  • the visualization of the neediness distribution can be done in particular by applying a color coding, ie a certain need for dressing a certain color is assigned.
  • a color coding ie a certain need for dressing a certain color is assigned.
  • the color yellow can be assigned to a dressing requirement of 50 ⁇ m, the color red to a dressing requirement of 10 ⁇ m, etc.
  • the visualization can be carried out in various ways. For example, the visualization can be achieved by outputting on a screen or a display done. If the punching knives and creasing knives are also displayed on the screen or display, the machine operator can quickly see where they need to be trimmed.
  • the visualization takes place outside the sheet punching and / or embossing machine in a trimming device, where the surface of the tool is illuminated with light in different colors in accordance with the color coding.
  • the visualization is done by output in printed form on an arc as a print image.
  • the printed image has the same dimensions as the tool and the sheet can serve as a dressing sheet, on which thin strips of adhesive are applied in accordance with the need for dressing.
  • the trimming can be done by pasting the punching and / or knives of the tool with adhesive strips, so-called dressing tapes.
  • the trimming is possible as surface finishing by depositing the tool with thin sheets of paper, such as tissue paper, plastic or the like.
  • the trimming by introducing a according to the need for trimming with a height profile provided plate between the tool and crucible is another possibility.
  • the plate may be, for example, a plastically deformed plastic plate, as for example in the DE 39 28 916 C1 is described.
  • Such a plate could also be produced by means of a so-called “layer-laminate-manufacturing” method, or by a different layered structure of the plate or by stratified removal of the plate (eg by eroding or etching, as is known from the production of punching plates for rotary die-cutting). ,
  • the measurement of the pressure distribution, the calculation of a demand for desming and the storage of the need for dressing are carried out once so that the machine-specific topography of the upper and lower crucible is taken into account.
  • the tool used is then - based on the crucible-specific need for additional needs - then a dressing of the tool.
  • the measurement of the pressure distribution to increase the machining accuracy is performed even after changes to a tool and / or after replacement of a tool.
  • the measurement of the pressure distribution is carried out at specified time intervals, so that changes in the pressure distribution can be determined a corrected demand distribution and the tool can be further trimmed.
  • the pressure distribution sensor is a piezoresistive pressure sensor, in particular a piezoceramic pressure sensor.
  • Such pressure sensors combine the advantages of high resolution with high power capability.
  • the invention further relates to a method for surface correction of crucibles of a flat bed sheet punching and / or embossing machine, which has at least one punching and / or stamping station, each having an upper and a lower crucible.
  • a first method step the pressure distribution in the at least one punching and / or stamping station is measured with a flat, in particular foil-shaped, pressure distribution sensor extending over the surface of the crucible. It is particularly advantageous to carry out the measurement at working pressure. After the measurement, the pressure distribution sensor is removed again and a correction requirement distribution based on the measured values is calculated.
  • a surface treatment is carried out on at least one of the two crucibles, whereby a uniform theoretical pressure distribution over the entire surface of the crucible is to be achieved.
  • a special plate with high parallelism can be installed during the measurement in the punching and / or embossing station.
  • Particularly advantageous is the use of a grid, which depicts individual points as a grid. Due to this unique surface correction of the crucible is achieved in an advantageous manner that the dressing needs in all in the punching and / or- Embossing tools used the dressing needs is reduced and thus significantly reduces the time required for trimming the tools.
  • the topography of the crucible of the punching and / or embossing station is determined and the trimmings need distribution of the punching and / or embossing station is stored.
  • the dressing can take place outside the sheet punching and / or embossing machine in a trimming device, for example a stamping station of a further sheet punching and / or embossing machine.
  • the topography of the trimming device is likewise determined and stored by measuring the pressure distribution by means of a sheet-like, in particular film-shaped pressure distribution sensor.
  • the tool is used in the trimming and again the pressure distribution determined and stored.
