Definitions

  • the present invention relates to a method for producing a cutting and / or punching and / or scoring tool comprising a carrier plate for receiving at least one cutting and / or scoring and / or scoring line.
  • the invention further relates to a corresponding carrier plate and a punching and / or scoring and / or scoring tool with at least one such carrier plate.
  • Punching, scoring and / or scoring tools for linear cutting, scribing and / or grooves of foldable materials usually comprise support plates which have receiving slots into which so-called cutting, scoring and / or scoring lines are inserted as insertion sections with a respective desired shape .
  • Such punching, scoring and / or scoring tools are mainly used in paper and cardboard processing, for example, cut out for folding cartons blanks of foldable materials and to provide by scratching and / or line embossing with folding or tearing lines.
  • other suitable materials such as corrugated cardboard, plastic films and the like can be processed.
  • a combined scoring and cutting tool is for example in the EP 1 238 793 A1 described.
  • the tool includes scoring and creasing lines, which are pressed non-positively into slot-shaped recesses of a carrier plate.
  • a disadvantage of the known method for producing such punching, scoring and / or scoring tools is the fact that changes in the layout of the punching and / or scoring and / or scoring tool are very expensive to carry out. If necessary, this significantly increases the cost and delay the production process of the punching and / or scoring and / or scoring tool.
  • Another object of the invention is to provide a carrier plate for a cutting and / or punching and / or scoring tool as well as a corresponding cutting and / or punching and / or scoring tool, which rapid and economical production even with possible corrections and / or change the design of the cutting and / or punching and / or scoring tool enable.
  • a first aspect of the invention relates to a method for producing a cutting and / or punching and / or scoring tool comprising a carrier plate for receiving at least one line from the group of cutting and / or scoring and / or creasing lines, according to the invention
  • Support plate of the cutting and / or punching and / or scoring tool is produced by a generative manufacturing process.
  • at least one projection for receiving and fixing at least one plastic or elastomeric strip is also formed on the support plate, wherein the projection is manufactured in one piece with the support plate generative.
  • the cutting and / or punching and / or scoring tool in its entirety by means of the generative manufacturing process.
  • at least one or more of the lines from the group of cutting and / or scoring and / or creasing lines are produced by the additive manufacturing process and arranged as a separate element on the support plate or formed integrally with the support plate.
  • the at least one to be arranged on the support plate plastic or elastomeric strip can be arranged as a separate element on the support plate or formed integrally with the support plate.
  • the plastic or elastomeric strip can be used under clamping action.
  • the said plastic or elastomeric strip may be a so-called gumming which provides for springback of the material to be punched by means of the cutting and / or punching and / or scoring tool.
  • the material to be punched may be paper, cardboard or plastic, in particular for the production of packaging blanks or packaging films. Other materials are conceivable.
  • the method according to the invention offers the possibility that individual or even all elements of the cutting and / or punching and / or scoring tool to be produced can be constructed generatively on a prefabricated, generatively produced carrier plate.
  • the support plate may, for example, at least partially made of a composite material, in particular a carbon fiber reinforced composite material and / or at least one material from the group steel, aluminum and plastic.
  • the carrier plate it is possible for the carrier plate to be produced generatively and to have at least one fit and / or opening for receiving and / or fastening the embossing element.
  • the generatively manufactured elements of the cutting and / or punching and / or scoring tool have the same or different degrees of hardness relative to each other and / or within the single element. For example, a line may have different hardnesses. The same applies to the plastic or elastomeric strips.
  • different requirements for the generatively manufactured elements according to the respective purpose can be easily met with a minimum process cost.
  • the inventive method is particularly fast and inexpensive to carry out.
  • it is possible to react very quickly and flexibly to possible changes in the design of the cutting and / or punching and / or scoring tool.
  • the generative production method is a stereolithography method, a digital light processing method, a 3D printing method, a melt layer method, a multi-jet modeling method, a selective laser sintering or selective laser melting method, an electron beam melting method or a combination of these methods ,
  • the use of single or a combination of these manufacturing processes depends on the product to be manufactured.
  • a cutting or creasing line and a corresponding carrier plate can be made of different materials and different additive manufacturing processes.
  • these are also selected when using different materials or different generative manufacturing processes so that different elements of the cutting and / or punching and / or scoring tool can be manufactured in a generative manufacturing step.
  • a stereolithography method is used as the additive manufacturing method
  • at least one liquid, photosensitive plastic material and / or a synthetic resin and / or a photosensitive lacquer may be used as the material.
  • a material for the selective laser sintering or selective Laser melting can be used at least one plastic, synthetic resin, metal, metal alloy or ceramic or a combination of these materials in powder form.
  • it is possible to use as material for the 3D printing process at least one UV-curing lacquer and / or at least one UV-curable ink.
  • materials for additive manufacturing processes as well as other, not mentioned generative manufacturing processes can be used according to the invention.
  • the carrier plate can be produced generatively and have at least one recess for receiving a cutting and / or scoring and / or creasing line. It is possible that the recess has a width which is slightly smaller than the width of the cutting and / or scoring and / or score line. Thus, the corresponding line can be subsequently inserted and secured in the carrier plate in a clamped and accurate fit.
  • the at least one cutout with respect to the line is produced with a predetermined oversize and the method comprises the following further steps: filling the cutout with a curable filler material; Curing the filler material in the recess; Generating at least one further second recess in the cured filling material for dimensionally accurate recording of the line and insertion of the line in the dimensionally accurate second recess.
  • the recess or recess can in principle be groove-shaped, hole-shaped or slot-shaped, interrupted and / or continuously generated as a function of the line to be used later.
  • the first recess is filled with the curable filler.
  • the first recess can basically be filled completely or only partially. Likewise it can be provided that several different filling materials are filled successively or simultaneously in the first recess. After hardening of the filling material or of the filling materials in the first recess, a second, dimensionally accurate recess is produced in the hardened filling material into which finally the cutting and / or scoring and / or scoring line is inserted.
  • the material of the carrier plate plays only a subordinate role in this respect that is given in comparison to the prior art, a much higher flexibility in the selection of the carrier plate material.
  • the curable filler which later holds the line to the carrier plate, can be selected independently of the carrier plate material. For example, a filling material can be used, which has a higher clamping effect after curing compared to the carrier plate material.
  • the second recess which can also basically be groove-shaped, hole-shaped or slot-shaped, interrupted and / or continuously generated depending on the line to be inserted, can be introduced precisely into the hardened filling material instead of into the carrier plate material.
  • the filling material can be removed, for example by milling, without destroying the carrier plate. Refilling the first recess with further filling material and the renewed formation of the second recess for receiving a line are readily possible. It is also possible that only the incorrectly positioned second recess is filled with filler again. After a renewed curing of the filling material, the second recess can be made new. The production of the tool can in turn be cost-saving, since with possible corrections of the positioning of the lines no completely new tool produced or a new carrier plate must be used.
  • a second aspect of the invention relates to a carrier plate of a tool from the group of punching and / or scoring and / or scoring tools, with at least one line from the group of cutting and / or scoring and / or score lines. It is inventively provided that the carrier plate is obtainable and / or obtained by means of a method according to one of the embodiments of the first aspect of the invention.
  • at least one projection for receiving and fixing at least one plastic or elastomeric strip is formed on the support plate, wherein the projection is manufactured in one piece with the support plate generative.
  • the carrier plate can be easily and inexpensively manufactured become. Further resulting features and advantages thereof can be found in the descriptions of the first aspect of the invention, advantageous embodiments of the first aspect of the invention are to be regarded as advantageous embodiments of the second aspect of the invention.
  • a third aspect of the invention relates to a punching and / or scoring and / or scoring tool with at least one carrier plate, which comprises at least one line from the group of cutting and / or scoring and / or score lines. It is inventively provided that the carrier plate is obtainable and / or obtained by means of a method according to one of the embodiments of the first aspect of the invention.
  • at least one projection for receiving and fixing at least one plastic or elastomeric strip is formed on the support plate, wherein the projection is manufactured in one piece with the support plate generative.
  • the punching and / or scoring and / or scoring tool according to the invention can be produced precisely, simply and inexpensively.
