Definitions

  • the invention relates to a hold-down for speed machines, in which material blocks are processed or processed from soft material, preferably for foam contour cutting machines, height-adjustable parallel to a receiving table hold-down plates, wherein the cutting machine held at least one of two bars of a cutting machine stand, the width the material block has adjustable adjustable center holder for the cutting tool has.
  • the invention further relates to a method for operating a hold-down.
  • the horizontally, vertically or virtually arbitrarily oriented cutting tool generates displacement forces on the workpiece to be cut as it enters the foam and also during cutting.
  • the forces arise, inter alia, by the friction between the tool and foam as forces in Oszlllations- or Thomaskanalllindsraum, as well as due to the Aufkeil fürsraum, as well as due to the Aufkeil fürsraum, as pushing forces in the feed direction. Both directions of force are approximately perpendicular to each other.
  • the forces create at least local shifts of the foam which ultimately result in inaccuracies of the cut contour.
  • the size of the displacements depends on various factors, including the material properties of the workpiece and the geometrical design of the cutting edge of the tool.
  • the shifts are inherently greater in the upper region of the unhindered foam block than in the lower region near the contact point on the take-up table. This is due to the fact that the receiving table carries the foam, which leads to very exact positioning and correspondingly small displacements in the region of the boundary layer between the foam and the receiving table with a high coefficient of friction. The farther away from the boundary layer, the less the counteracting effect is of the shooting table, so that with increasing distance from the receiving table, the shifts are greater.
  • a counter-holder is installed on the foam, which has a similar effect with respect to the displacements as the receiving table below the foam.
  • This counterholder is called downholder.
  • Hold-downs in foam cutting machines are known. They serve to clamp the foam block or the foam sheet stack between the receiving table and the hold-down in order to stabilize and calm the material lying on the receiving table so that when cutting, especially during contour cutting, the material block as little as possible deflected by the cutting tool . is set in natural vibrations, so that the most accurate contour cuts are possible.
  • Cutting machines have already been developed with hold-downs, which are directly connected to the receiving table and held in a frame hold-down plates. Due to this construction, the receiving table builds very heavily, which has a disadvantageous effect in the case of movable receiving tables in their acceleration behavior. In addition, the high frame structure can lead to unwanted vibrations during the feed during the cut, which in turn adversely affects the cutting accuracy.
  • These cutting machines have a center holder which causes the free bending length of the knife to be shortened, causing a significant reduction in the deflection of the cutting tool depending on the degree of shortening. As a result, in turn, the cutting tolerances resulting from the bending and bending of the cutting tool are usually reduced.
  • hold-downs have been proposed that are equipped with hold-down rollers.
  • the hold-downs are arranged height-adjustable on the machine stands.
  • the rollers have, at least in the area of the center holder, at a distance, which ensures that the center holder can be easily moved transversely.
  • a disadvantage of the roller retainers is that the soft material blocks are not adequately supported, at least for certain cutting tasks. Instead of a surface support of the blank holder, only a line support of the rollers is given. Between the rollers, the soft material can not be held down. For complicated contour cuts, this small contact surface can lead to waste during cutting.
  • the invention has the object of developing a generic hold-down so that in spite of optimally large edition a fast, automatic change of blocks with appropriate transverse displacement of the center holder, as well as a discharge of the receiving table of weight and unwanted vibrations during operation is guaranteed.
  • the hold-down has support elements which are mounted vertically adjustable on the bars, that the support elements carry a hold-down frame, that the hold-down plates are guided longitudinally displaceable in the hold-down frame, and that the hold-down plates at least in the region Center holder have a width of the center holder excess gap-shaped distance to accommodate the center holder between them can.
  • hold-down plates are moved longitudinally, they can be moved to a position outside the collision area with the center holder.
  • the middle holder can now be moved transversely.
  • the receiving table is particularly easily accessible for loading and unloading.
  • the hold-down plates can be moved back again. Care must be taken only that the hold-down plates in the area in which the center holder is spaced from each other. This results in the advantage of a, at least in the area above the cutting tool large-area support of the blocks of material, which is compared to the support by roller hold substantially better and more effective.
  • a working on the cut disadvantageous fulling of the block of material, as in the roll hold-down is excluded.
  • the hold-down plates also allow the processing of small individual blocks that could no longer or only insufficiently be processed with a roller hold-down device.
  • the mechanical connection of the hold-down takes place detached from the receiving table on a separate height adjustment.
  • the receiving table remains unmolested by the additional mass of the blank holder, so that its position control loop is not affected. Also possible longitudinal vibrations, which in turn would adversely affect the cutting tolerances, are avoided.
  • the support table may be stationary or movable, be equipped with or without loading belts or even be designed as a table-top system, in which a fixed or movable support table is equipped with at least one conveyor belt for moving and positioning the foam block. If Either the support table as a whole or the band of the tabletop system realizes the function of the displacement or positioning, then the support table represents one of the NC axes of the foam cutting machine. With a fixed support table, the corresponding movable cutting unit usually represents an NC axis NC axis is realized in most cases by the vertical movement of the cutting unit or the cutting tool.
  • a rotating knife or a wire which acts as a cutting tool, hereinafter also referred to as knife, and whose rotation represents the third NC axis.
  • the rotation means that in the cutting area the leading edge of the knife is tracked in the cutting direction; this happens through z.
  • the hold-down plates are arranged in a fixed grid of hold-down plate to gap, and that the hold-down is transversely adjustable in this fixed pitch. This results in a simple machine control, the corresponding grid can be specified.
  • the number and arrangement of the hold-down plates is almost freely configurable before the construction of the machine, but on the fully assembled machine can not be easily changed.
  • the hold-down plates are to be arranged so that gaps of typically z. B. arise 130 mm in between. In one of these gaps of the center holder is arranged, which contains a knife guide at its lower tip.
  • the hold-down plates in order to be able to adjust the arrangement of the hold-down plates more freely, it is also possible for the hold-down plates to be detachably held on the hold-down frame and mounted transversely displaceable relative to one another.
  • the gap required for the hold-down can be realized at any point by moving the hold-down plates.
  • the hold-down plates are adjustable in their width. With these preferably automatically telescoping hold-down plates an even more flexible adjustment of the hold-down surface and the gap for receiving the intermediate holder is ensured.
  • the longitudinal displacement drive of the receiving table and the longitudinal displacement drive of the hold-down plates must be coupled to each other via couplings. It is advantageous, however, if the synchronization by electrical or electronic means, for. B. according to the system Mother / Chield is realized.
  • the recording table as a mother gives appropriate impulses to the drive of the hold-down plates, which acts as a chield.
  • the figures show the machine stand 1 and a receiving table 2 of a cutting machine.
  • the cutting unit 3 is guided adjustable in height.
  • the hold-down 4 has support elements, which are guided vertically adjustable on the machine frame 1.
  • the support elements carry a hold-down frame 6, which in turn holds hold-down plates 7 to 10 longitudinally displaceable.
  • the hold-down plates 6 to 10 are arranged above the material block 11.
  • the indicated blade 12 is supported by a center holder 13 in addition to the brackets in the blade unit 3.
  • the center holder 13 is positioned in the region of a gap 14.
  • the hold-down plates 6 to 10 can be moved longitudinally without bumping them against the center holder 13.
  • FIGS. 3 and 4 the hold-down plates 6 to 10 are then moved to the left.
  • the center holder 12 can be traversed 6 to 10 without problems in this position the hold-down plates without problems.
  • the hold-down plates 6 to 10 are moved.
  • the hold-down plates 6 to 10 can again move back into the position FIG. 1 be moved.
