Definitions

  • the invention relates to a cutting device, in particular a transverse dividing shear, a longitudinal dividing shear or roll cutting (edging) scissors for cutting sheets according to the preamble of claim 1.
  • WO 2008/135127 A1 shows a further cutting device for cutting sheet metal plates, with a first cutting blade of an upper blade and a
  • BEST ⁇ TJGUNGSKOPIP second cutting blade of a lower blade which further comprises a drive device with at least two rotatably driven eccentric shafts, which are connected by means of connecting elements from above with the first cutting blade, wherein at least one of the connecting elements between the drive of the blade and the upper blade is adjustable in length.
  • the device disclosed in this document has similar disadvantages as those of the above-described document.
  • the upper blade is articulated laterally such that a rolling motion can not be realized for many sheet thicknesses and widths.
  • the cutting movement is the same for all sheet thicknesses and limits the cutting thickness of the machine.
  • FIG. 1 a shows a further example from the prior art, which is guided by means of a rotatable link 30.
  • the upper blade 10 is in turn moved in this case by two electromechanical drives 40, each of which has lengthwise adjustable connecting rods.
  • the lateral linkage 30, however, takes place with a fixed length.
  • the ideal rolling motion can only be determined constructively for a defined immersion depth of the upper knife 10. This results in sheet metal deformation (such as shear bends) and a general deterioration of the cut quality.
  • Figure 1 b shows another example of a cutting device of the prior art, which shows a system of an upper and a lower blade 10, 20, wherein the upper blade 10 is hydraulically driven (41) and articulated again laterally with fixed length.
  • Figure 1c shows a similar cutting device as Figure 1 b, but with a hydraulic drive 42, the lower and upper blades 20, 10 interconnected.
  • the technical task is to provide a cutting device which avoids at least one of the above-mentioned disadvantages or further develops the above-mentioned devices.
  • the cutting device in particular a cross-cutting scissors, slitting shears or roll cutting scissors for cutting sheets, which comprises an upper blade and a lower blade and at least one drive device which is connected to the upper blade and / or the lower blade for driving the cutting operation and wherein the device comprises a side guide for guiding the upper blade, which is designed to be adjustable in length.
  • the overcut of the knives is thus adjustable. Due to the inventive possibility of length-adjustable side guide now a better quality of cut can be guaranteed. This mainly concerns cuts of different sheet widths and thicknesses. The range of cutting widths and thicknesses can be significantly extended according to the invention. The above-mentioned disadvantages can be avoided as far as possible.
  • the side guide is connected at one end to the upper blade and at another end to a pivot point, which is arranged laterally of the upper blade.
  • the side guide on an adjustment for length adjustment.
  • the side guide comprises a rotatable cam, so that the side guide can be adjusted in length.
  • the side guide comprises a sliding block whose guideway is designed spatially variable so that the side guide can be adjusted in length.
  • the side guide comprises hydraulic or pneumatic means for length adjustment of the side guide.
  • the lateral guide comprises electromechanical means for adjusting the length of the lateral guide.
  • the side guide on a threaded rod or a threaded spindle and at least one, preferably two threaded sleeves, which are designed such that the side guide can be adjusted in length.
  • the cutting device is designed such that the side guide comprises a connecting element, which is connected at one end to the upper blade and connected at another end to a pivot point or a shaft.
  • the connecting element is formed mechanically drivable at the other end and in particular mounted on a rotatably driven eccentric shaft.
  • the connecting element is mounted on the eccentric shaft on an eccentrically adjustable articulation.
  • the invention comprises a method for controlling a cutting device, in particular a transverse dividing shears, slitting shears or roll cutting shears for cutting metal sheets, which comprises an upper knife and a lower knife and at least one drive device which is connected to the upper knife and / or the lower knife for driving the cutting operation and wherein the cutting device comprises a side guide for guiding the upper blade, which can be adjusted in length.
  • a cutting device in particular a transverse dividing shears, slitting shears or roll cutting shears for cutting metal sheets
  • the cutting device comprises a side guide for guiding the upper blade, which can be adjusted in length.
  • At least one of the following parameters is taken into account for setting the side guide: cutting angle, immersion depth of the upper knife, material thickness, material width and / or material properties.
  • Figure 1a shows a cutting device of the prior art with lateral
  • FIG. 1b shows another example of one known from the prior art
  • Figure 1c another known from the prior art cutting device with lateral articulation
  • Figure 2 shows an embodiment of a cutting device according to the invention with hydraulically adjustable lateral linkage
  • Figure 3 shows another embodiment of a cutting device according to the invention with eccentrically adjustable lateral guide.
  • FIG. 1 An embodiment of a pair of scissors according to the invention is shown in FIG.
  • the upper blade 1 is connected at its top with conventional drive units 4.
  • the lower blade 2 is fixedly mounted in the embodiment, but may also be designed to be movable.
  • This lateral guide 3 is laterally of the upper blade 1, preferably essentially in FIG Direction of the longitudinal axis of the upper blade 1, arranged. In particular, this is preferably connected at one end to the upper blade 1 and at another end to a pivot point which is located laterally of the upper blade 1.
  • a point of articulation of the lateral guide 3 on the upper blade 1 may preferably be provided at different heights on the side of the upper blade 1. This also applies to the articulation point, which is located laterally of the upper blade 1 at the other end of the side guide 3. Due to the lengthwise variable, lateral guidance, a rolling movement of the upper blade 1 can be ensured for all drive states of the cutting movement. This also applies if, for example, the connecting rod lengths of the drive 4 are varied or eccentric shafts are used on the drives 4. In the case of FIG. 2, the variable lateral guide 3 is ensured by hydraulic or pneumatic piston-cylinder units.
  • adjusting the lateral guide 3 for example, optionally given by a spatially varying guideway for at least one sliding block or by the use of a well-known rotatable cam for lateral guidance.
  • a piston-cylinder unit in particular the handlebar length can be adjusted continuously.
  • FIG. 1 Another possibility according to the invention for providing a laterally variable articulation is shown in FIG.
  • the structure is essentially analogous to the structure of FIG. 2.
