Definitions

  • the invention initially relates to a device for punching ribbon and sheet material, especially cardboard, with a so-called crucible area, in which a band steel cut is opposite one fixed or adjustable on a carrier plate arranged counter punching plate bearing a punch engraving is present, the carrier plate one for Steel strip cut and one directed towards the crucible area Has area.
  • Such a device is, for example, from the DE-GM 93 08 628.8 known in which a device for precise, changeable assignment of the steel strip and a counter punching plate with arranged on it Die shown within a punching machine and is described.
  • the object of the invention is therefore to create a new one To create a support plate, which is basically a larger one Shows punching time with great accuracy.
  • this carrier plate consists of the fact that after the production the connection of base plate and hard metal plate the latter can be ground with high precision. About that furthermore, after a longer punching time it is the very stable hard metal plate with little effort possible - in contrast to plastic or aluminum carrier plates - any irregularities in the surface, that can be recognized from the printed image, grind flat. Against this is the restoration of planicity problematic of pure plastic or aluminum plates, because aluminum is too soft, while plastic there is the problem of the fiber content, which the liquid supply of the wet grinding machine every grinding process of a carrier plate must become.
  • carrier plate according to the invention in which one "used" carrier plates from, for example Plastic after a reduction in thickness as the base plate used and attached a hard metal plate, which is then ground flat.
  • the carrier plate has two on both sides of the base plate Arranged hard metal plates, whereby the Overall service life of a carrier plate increased becomes.
  • the production of hard metal plates from corrosion-resistant Steel has a particularly advantageous effect on the long-term quality of the surfaces of the hard metal plates out.
  • the invention are partially between the Base plate and the carbide plate (s) that Intermediate layers compensating the printed image of the punching machine arranged. So should be due to millions Punching in the crucible area or due to design-related peculiarities of a certain Machine type on the carrier plate or the crucible table partially resulted in certain changes that the May affect the printed image of the punching machine one in the production of a carrier plate according to the invention take this into account accordingly in that one has, for example, a pressure hole Intermediate layers between the areas sandwich-like structure of the carrier plate.
  • Such intermediate layers are known to achieve a general compensation, for example, stick on a carrier or stamping plate.
  • the intermediate layers firmly within the layered Structure of the carrier plate integrated. This is about So it is a special on the specifics adapted to a machine type or a machine Carrier plate.
  • the carrier plate according to the invention is therefore dependent on the determined print image partially convex and / or concave.
  • the invention further relates to Process for producing a support lath for punching machines according to claim 1 or one of the following used carrier plates, in particular made of plastic.
  • a new carrier plate becomes an economical one created a very advantageous opportunity that in Principle of very expensive but used carrier plates to be recycled at least in part. This is an advantage in particular because since one essentially consists of a "used" carrier plate manufactured new carrier plate a larger Service life has as a carrier plate according to the status of the technique.
  • the device 10 consists of a so-called Crucible area 11, a stripping station 12 and one Plant separation station 13, the interval transport of punched sheets 14 prepared for punching a gripper chain 15 is carried out.
  • the actual punching process takes place in the crucible area 11 instead, in which a punched sheet 14, e.g. made of cardboard, a larger number of benefits 16 (Blanks) is manufactured. While in the stripping station 12 the edge sections are removed from the panels 16 will be found in station 13 afterwards a separation of the individual benefits 16 instead.
  • a punched sheet 14 e.g. made of cardboard
  • the gripper chain 15 In the crucible area 11 is above the movement path the gripper chain 15 has a punch 17 arranged stationary, which is called a band steel cut, while below one can be moved in the machine frame mounted support plate 18 is present.
  • a counter stamping plate 19 in the corner areas 20 On the carrier plate 18 shown in FIG. 2 is a counter stamping plate 19 in the corner areas 20 provided, not shown, holding screws attached.
  • the in the corner regions 20 of the support plate 18th have holes provided for the retaining screws Excessive, so that a shift in the limits Counter punching plate 19 in a gripper direction a (Direction of movement of the gripper chain 15) and one Counter gripper direction b and an operating direction c and a counter-operating direction d on the carrier plate 18 is possible.
  • Under the operator side means the side of the device 10 from which the Carrier plate slidably guided in the machine frame 18 is inserted into the crucible area 11.
  • the counter punching plate 19 is the carrier of one or several stamping die (s) 21, which e.g. from Pertinax consist. As shown schematically in FIG a larger number of dies 21 on the counter-punching plate 19 arranged that possible with a punch stroke many benefits 16 are created, taking up the area the counter-punching plate 19 can be optimally used should.
  • stamping die e.g. from Pertinax consist.
  • the band steel cut is effective when punching 17 and those arranged on the counter-punching plate 19 Matrices 21 together, which with creasing, scratching or Perforation lines is provided.
  • die 21 is on a CNC controlled Machine milled and then on the counter stamping plate 19 attached.
  • a die cut 14 is cut using the gripper chain 15 between steel cutting 17 and counter-punching plate 19 transported, then in the course of a so-called Stanzhubes the two tool halves under Production of the benefit 16 to be pressed together.
  • FIG. 2 shows the unit Carrier plate 18 and counter-punching plate 19 - as in FIG. 2 indicates - an adjustment unit, not shown, and a clamping unit through which the counter-punching plate 19 moves on the carrier plate 18 in a defined manner can be braced. While the adjustment unit in a recess 22 of the carrier plate 18 or the counter-punching plate 19 is arranged, the clamping unit in a recess 23 attached.
  • the carrier plate shown in Fig. 2 has the peculiarity that it consists of a base plate 24 made of plastic and a hard metal plate 25 directed to the steel strip cut 17, which are glued together. While the base plate 24 has a thickness D 1 of approximately 20 mm, the thickness D 2 of the hard metal plate is only approximately 1.5 mm.
  • the base plate 24 and Carbide plate 25 existing carrier plate 18 with two so-called insertion lugs 26, the counter operator side on an end face 27 of the carrier plate 18 are attached.
  • the insertion lugs 26 should be simple and above all damage to the carrier plate 18 avoiding insertion of the carrier plate 18 including counter stamping plate 19 in the crucible area enable.
  • FIG. 3 is yet another embodiment a carrier plate 18 shown.
  • the carrier plate 18 in turn is a base plate 24 and an upper hard metal plate 25, however, in addition another hard metal plate 28 leading to the crucible area 11 points.
  • the arrangement of Carbide plates 25 and 28 on the base plate 24 the service life of the carrier plate 18 overall even further extended.
  • FIG. 6 is that shown in FIG. 2 Carrier plate 18 without counter stamping plate 19 in Cut shown. It can be seen that the lower hard metal plate 28 by means of an adhesive layer K on the base plate 24 is attached while the upper hard metal plate 25 is screwed detachably to the base plate 24 (see schematically indicated screw connection S).
  • the Detachable arrangement of the upper hard metal plate 25 important in that it is possible between the upper hard metal plate 25 and the base plate 24 intermediate layers in the area of pressure holes 29 between the sandwich structure of the To lay carrier plate 18.
