  • Workpieces are usually sheets or (sheet) blanks, which usually undergo a plurality of cutting operations in the context of manufacturing processes.
  • machine and cutting method are most suitable for these cutting operations.
  • These cutting operations include, for example, shear cutting and laser cutting.

Depending on the material and tool design, these requirements can be fulfilled more or less well.
  • shear cutting soft and tough materials tend to have a high proportion of smooth cut and a low outbreak, with a vertical cutting process. In return, however, higher values for the entry and the ridge must be accepted.
  • Curing in the edge occurs mainly on soft or tough materials. They are the result of massive displacement changes along and in the depth of the edge.
  • the invention is therefore based on the object of specifying a method and a device for cutting a workpiece, with which in particular the wear of the cutting means is lowered and at the same time an improvement or at least no deterioration of the cut edge quality is achieved.

  • both sides of the workpiece to be cut are fixed between the workpiece holders and the contact surfaces such that retightening of the workpiece from a region not to be cut during the cutting process is substantially prevented.
  • the first cutting means is not yet in contact with the workpiece during the clamping step. It is further preferred that the two workpiece holders move synchronously toward the workpiece and react like a component rigidly connected to one another.

  • the edge loading of the tools and the adjoining surfaces of the tools is considerably reduced, which in turn means a longer tool life and a better cutting quality of the workpiece to be cut.
  • the cut strip of the workpiece to be cut which was located between the two cutting edges of the cutting means during the cutting process, falls into the gap. Since the cutting waste preferably has a narrow width, the loss of material is very low.
  • the inventive method is particularly suitable for cutting high-strength and brittle materials, but can also be used for cutting soft and tough materials.

  • the method according to the invention it is possible to achieve high smooth-cut portions, a small outbreak without notch effect, a reduced indentation and a very good angularity of the cut surface.
  • the mentioned effects furthermore result in that the operational stability of the cut edges is increased.
  • the absence of burrs ensures that there is no need for reworking and injuries caused by a burr in the handling of the workpiece can be avoided.
  • the good or the waste side are defined in normal cutting operations by the cutting line of a workpiece to be cut. Normally, the good side contains the part of the workpiece which is used for further processing, for example in production.
  • the parts of the workpiece which are not enclosed by the two cutting lines defined by the cutting edges of the first cutting means and the second and third cutting means can be used for further processing. Accordingly, these areas are referred to in the context of the invention as the first Gutseite and as the second Gutseite.
  • the area between the two cutting lines, in which the part of the workpiece is arranged, which can not be used for further processing and after cutting as a cut strip falls into the gap is referred to in the invention as a waste area.
  • the method can be carried out in particular by a device according to the invention, which will be described in more detail below.
  • an open cut is produced by the cutting process by means of the cutting means.
  • a closed cut for example during punching, the opposite sides of the workpiece are necessarily also cut and the cutting system is largely free of lateral forces. this leads to automatically to a low cutting edge load and thus low wear.
  • open cuts are those cuts which do not have a closed cutting line in the relevant cutting region.
  • a typical cutting process for creating open cuts is clipping.
  • the open cut may have a substantially straight cut line.
  • the cut quality of a waste area is generally worse than the cut quality of a good side, especially since the waste area has no counter-holder down.

  • the combination of an open cut and a double cut makes it possible to combine the advantages of closed cuts (for example, avoidance of shear forces) with the advantages of open cuts (eg less exclusion).
  • the cutting operation is carried out by means of the first cutting means and the second and third cutting means substantially simultaneously. This ensures that the cut quality in both cuts in the is identical. In addition, due to the cuts made at the same time, essentially identical transverse forces are generated which, as a result of their countervailing vectors, thus at least largely cancel each other out, as a result of which the load on the cutting means is reduced.
  • the first cutting means is guided by the workpiece holders and is connectable to a plunger, wherein the plunger is moved for cutting the workpiece relative to the workpiece holders.

Further, it is preferred that during clamping, a deflection in the region of the workpiece, which is arranged between workpiece holders, is substantially avoided. This is preferably due to a small distance between the two cutting lines to each other or the small width of the waste area. As a result, the part of the workpiece to be cut located in the waste area is clamped between the second cutting means and the third cutting means, whereby bending of the workpiece in the waste area during the clamping step is prevented. This has the effect of providing contrast-cut-like conditions, which results in burr-free cut surfaces, a high level of smooth cut and a very high angularity. According to a further preferred embodiment, the workpiece during the
  • This feed-free cutting process can be prevented by a sufficient force application of the workpiece holder or by provided on the workpiece holders teeth. As a result, the quality of the cut edges is further increased and, in particular, the feed is prevented.
  • a curved cutting profile is generated by the cutting process by means of the cutting means.
  • the cutting edges of the first cutting means are preferably designed as hardened and sufficiently thin flat or strip material, which can lead to a simple exchange with a prefabricated, hardened first cutting means. In special cases, this is also conceivable for the second cutting means and / or the third cutting means.
  • the field of application of the cutting method can be increased since first cutting edges for curved cuts can also be provided with this method. Due to the configuration of the cutting or cutting means as strip material, the maintenance intervals are reduced and the resulting costs are reduced.
  • the method is carried out in a cutting tool, in a guillotine cutter or in a lever shears.
