Definitions

  • the invention relates to a device for punching strip-like and sheet-like material, in particular cardboard, with a crucible area which has a steel strip cut and at least one adjustable counter-punching plate arranged in the crucible area, on the surface of which at least one die is arranged.
  • Such a device is already known from DE-GM 93 08 628.8 by the applicant.
  • a device for precisely fitting, changeable assignment of a steel band cut and a counter-punching plate with a die arranged thereon is shown and described within an automatic punching press, in which a counter-punching plate which is movably arranged on a relatively thick carrier plate can be moved and clamped in a defined manner via an adjusting unit and a clamping unit.
  • the block-shaped adjusting unit and clamping unit are arranged within marginal recesses of the carrier plate, with the counter-punching plate being moved and fixed via guide and clamping elements which protrude from the carrier plate
  • this device which is very advantageous in itself, has only one area of application in a punching machine which has a relatively thick carrier plate and a movable counter-punching plate arranged thereon.
  • punching machines are currently in use on the one hand, which have only a thin steel support plate with a thickness of approx. 5 mm, on which the actual counter-punching plate is arranged so that it cannot be adjusted.
  • punching machines are also known in which only a 5 mm to 10 mm counter-punching plate is likewise arranged in the crucible region in an unadjustable manner.
  • the object of the invention is therefore to provide a device for the targeted adjustment of thin counter-punching plates the exact alignment of the counter direction to the punching tool.
  • the counter-punching plate has a thinly arranged lower plate in the crucible area and a thin upper plate carrying the matrices, provided with freedom of movement, that both plates in x and y-direction are each slidably attached to one another via at least one guide / drive element and can be fixed to one another in the desired position by means of at least one locking element and that all guide / drive elements and locking elements are arranged essentially within the contour of the plates.
  • Such a device according to the invention has the essential advantage that a device for targeted adjustment is now also available for thin counter-punching / carrier plates.
  • punching presses which have only a thin carrier plate, on which a counter punching plate is firmly screwed, or punching presses with only one counter punching plate can now be retrofitted.
  • the device consists only of two thin plates forming the counter-punching plate, of which the lower plate is fixed in the crucible area and the upper plate is movably arranged on the lower plate by means of the guide / drive element and the locking element.
  • the counter-punching plate has two spaced-apart in the x-direction and two in the y-direction oriented guide elements, one drive element in the x- and in the y-direction and at least two locking elements which, when released, movements of the top plate enable in the x and y directions, the guide elements and the drive elements permitting movement of the top plate in each case transversely to their orientation or drive direction.
  • Such a device can also be easily retrofitted into an automatic punching press, only the guide, drive and locking elements having to be integrated into a fixedly arranged lower plate and a movable upper plate.
  • a preferred embodiment of the invention has a lower plate with at least two spaced-apart recesses in the edges, in each of which a guide / drive element is arranged to be movable in the x and y directions and is additionally connected to the upper plate in terms of movement.
  • Each recess can have a stepped widening on both sides at the edges, the guide / drive element consisting of one in the region of the widening with the lower plate firmly connected abutment plate and an adjusting unit arranged in the edge of the recess and displaceable in the x direction is formed.
  • the adjusting unit has an adjusting screw arranged in the x-direction, the head of which is mounted in the adjusting unit and the threaded part provided with key surfaces on the end engages in a threaded through bore of the abutment plate, the adjusting unit additionally having an adjustable in the y-direction, in one Bore of the upper plate protruding adjusting element according to claim 13.
  • a particularly preferred embodiment of the invention is characterized in that the two guide / drive elements are each formed from an abutment plate which is fixedly connected to the lower plate and an adjustment unit which is arranged in the guides at the edge of the recess and which has a slide which is adjustable in the y direction via an eccentric has, which is motionally coupled to the top plate and that the adjusting unit of one of the two guide / drive elements in the x-direction can be moved within the excessively large recess by means of a further eccentric arranged in the adjusting unit and abutment plate.
  • the device according to the invention has the particular advantage that it is of relatively simple and robust construction and that the number of its individual parts is limited. This of course also makes the device relatively inexpensive to manufacture. Ultimately, for adjusting the device according to the invention only the actuation of the key surfaces arranged on the eccentrics is necessary.
  • the two guide / drive elements are each formed from an abutment plate firmly connected to the lower plate and an adjustment unit arranged in the edge of the recess, which has a window-like depression with an inclination with respect to the coordinate cross arranged recess, in which an eccentric is guided, which has a protruding into the top plate, provided with key surfaces, with which the top plate is motionally coupled in the y direction and that the adjustment unit of one of the two guide / drive element in the x direction a threaded element arranged in the abutment part and extending in the x direction and engaging in the adjusting unit is movable within the recess having an oversize.

  • the top plate 96 can be placed in such a way that the pin top part 135 engages through an opposite through hole in the top plate 96, thereby achieving a coupling of movement between the top and bottom plates 96, 95 becomes.
  • plate 126, eccentric 132 and eccentric end plate 134 are referred to as adjustment unit V.
  • the guide / drive elements 124, 125 also each have an abutment plate 137, which is screwed to the lower plate 95. While in the guide / drive element 124 the abutment plate 137 is connected to the plate 126 via a threaded element 138 extending in the x direction, the guide / drive element 125 is made from two separate parts, namely on the one hand the abutment plate 137 and on the other hand the plate 126.
  • the plate 126 is first pushed together with the previously described parts into a recess adapted to the longitudinal guide 127 up to the stop, and then to Secure the abutment plate 137 against the plate 126 with the lower plate 95 is screwed.
  • the abutment plate 137 and the plate 126 in the guide / drive element 124 are connected via the aforementioned threaded element 138.
  • the abutment plate 137 has a through hole 139 running in the x direction and the plate 126 has an opposite through hole 140 which opens into a depression 141 for an insert component 142.
  • the insert component 142 is also provided with a threaded bore 143 opposite the through bore 140, so that the threaded element 138 can be screwed through the through bore 140 into the threaded bore 143.
