Definitions

  • the invention relates to a punching and creasing tool for production of grooved stamped parts according to the generic term of Claim 1.
  • Cardboard box blanks are usually received Creases, through which the folding boxes during later erection maintain their defined shape.
  • the contours as well as necessary Incisions in the folding box blank are made by Punching generated.
  • the production takes place by means of steel strip - stamping and Creasing tools on flat bed or rotary punches.
  • the band steel punching and creasing tools usually exist from a carrier plate made of wood, for example, connected Plastics with glass fabric or in sandwich construction Armored metal plates. In this carrier plates are made accordingly slots are introduced into the box contours that correspond to those Punching or creasing lines are included.
  • the punch lines are either exactly as far or further from the carrier plate like the crease lines.
  • the punch lines work against one Punching plate, mainly made of steel.
  • the crease lines create a crease in the folding box material by pushing the material into a groove.
  • This Grooved grooves can be milled into the punching plate or as a structure be attached to the punching plate.
  • the folding box material should be along the creases exactly and with a defined Folding resistance to be foldable. The folding process comes in particular of particular importance in cartoning machines because of the exactness and folding behavior of the creases the achievable Working speed of the cartoning machine depends.
  • the creasing line is Part of the carrier plate while the creases on the Punching-grooved plate are attached.
  • the slots for inclusion the crease lines are e.g. with laser NC controlled in the Carrier plate introduced.
  • Creasing grooves NC-controlled incorporated into the punching-creasing plate.
  • FR-A-2 315 368 which is considered to be the closest prior art, discloses a punching and creasing tool Production of grooved stamped parts from a sheet of material known that has a support plate on the underside Stamping elements are provided. Is between the stamping elements a grooved plate attached to the underside of creasing projections are trained. Between the carrier plate and the Grooved plate is provided by an elastic material, whereby the grooved plate also has an ejector function can meet to strip punched sheets. Under the A punching and scoring plate is provided in the carrier plate Grooved grooves are formed below the creasing projections. A exact level alignment of the grooved plate with respect to the Punching-grooved plate is not due to its elastic storage possible.
  • BE-A-664 540 also discloses a tool according to the preamble of claim 1.
  • a punch-creasing tool is known from EP 0 655 303 A1, in the punching and creasing lines in through openings one Carrier plate are included. The punching and creasing lines rest with their backs on a locking frame. Between the locking frame and a fixed machine plate a correction glue for height compensation Preparation sheet arranged. The positioning of the correction glue is made on the basis of trial punching and requires a lot of experience and sensitivity. This document suggests to place an elastic film made of polymethane between the machine plate.
  • the invention has for its object a punching and Creating creasing tool with which grooved - stamped parts can be made with high filling equipment.
  • the leveling elements of the punching and Creasing tools make it possible to relate the creasing projections of the grooved grooves formed in the punch-grooved plate on simple Way to align exactly when the carrier gap is one has an uneven underside.
  • centering holes are provided in the grooved plate, those with the first centering openings formed in the punch-grooved plate align if the crease plate is arranged so that the creasing protrusions exactly to the corresponding creasing grooves can be aligned through the center holes and the Dowel pins passing through the first centering openings for fixation the crease plate is used on the stamped-crease plate become.
  • the distance of the crease plate to the punch-crease plate can be adjusted by spacers through which the dowel pins go through.
  • the carrier plate can be precisely aligned with the punched and grooved plate using dowel pins be aligned when in the carrier plate Centering holes are provided, which are in the punch-grooved plate trained second centering openings are aligned.
  • dowel pins be aligned when in the carrier plate Centering holes are provided, which are in the punch-grooved plate trained second centering openings are aligned.
  • connection can be made temporarily by a between the carrier plate and the grooving plate provided adhesive, preferably a double-sided tape.
  • the grooved plate can be used for final fastening screwed to the carrier plate become.
  • the punching-creasing plate 10 shown in FIG. 1 is on a counter pressure plate (not shown) of a punching and creasing tool mounted horizontally.
  • a plurality of creasing grooves 12 for forming creases in a flat material to be processed, e.g. in a box, intended.
  • Area are four vertical first in the punch-crease plate 10
  • Centering openings 14 are provided, in each of which a dowel pin 20 is inserted.
  • the punch-crease plate 10 is one Grooved plate 16 arranged in the vertical center holes 18 are formed with the first centering openings 14 in the punch-crease plate 10 are aligned, the same diameter as these have and in which a corresponding in a respective first centering hole 14 inserted dowel pin 20 engages.
  • Each dowel pin 20 passes through a spacer 23 between the crease plate 16 and the punch-crease plate 10 is arranged.
  • the scoring grooves 12 On the underside of the scoring plate 16 are the scoring grooves 12 oppositely arranged creases 22, each are aligned exactly with the corresponding groove 12.
  • the Distance of the free end of the creasing projections 22 to the groove base the respective groove 12 is dependent on the groove to be grooved Flat material and the depth of the groove 12. This distance can be adjusted by means of the spacers 23.
  • the dowel pins 20 in the first centering openings 14th inserted so that it is from the top of the punch-crease plate 10 project. Then the spacers 23 on the dowel pins 20 put on.
  • the carrier plate 21 are 16 holes in the area above the grooved plate provided in which leveling bushes 34 by means of a clamp fit are attached, the lower end faces of which lie in one plane and to a small extent from the underside of the carrier plate 21 protrude.
  • Centering holes 24 are provided in the carrier plate 21, the one with second centering openings 26 in the punch-crease plate 10 align and have the same diameter as this.
  • the Carrier plate 21 is by means of dowel pins 28 on the punch-crease plate 10 fixed in each center hole 24 and the engage corresponding second centering opening 26.
  • a plurality of slots are formed in the carrier plate 21, in which each have a punching line 30 inserted so that you Back is flush with the top of the support plate 21 and the cutting edge 32 facing the stamping-scoring plate 10 is the stamping plate 10 touches when the carrier plate 21 on the grooved plate 16 rests.
  • a double-sided adhesive tape (not shown) is arranged, with which the grooved plate 16 provisionally on the End faces of the leveling bushings 34 in the carrier plate 21 is fixed.
  • the carrier plate 21 is attached the grooved plate 16 attached to it from the punched grooved plate 10 lifted off, and there are the dowel pins 20 and 28th away. Now the adhesive tape is used to temporarily Carrier plate 21 fixed grooved plate 16 by Screws (not shown) connected to the carrier plate 21, through the through openings 36 of the leveling bushings 34 go through and engage in threaded bores 38, the the top of the grooved plate 16 are provided.
  • the leveling bushings 34 serve to create a precise Support level, since the carrier plate 21 on its underside Can have bumps.
