INSTRUCTIONS OF THE INVENTION [Technical Fields of the Invention] The present invention relates to a double-sided trimming shear which has a stationary bottom blade and which can be driven by an eccentric shaft via a connecting rod in a manner that can be raised and lowered. The top blade, each connecting rod is disposed on its own eccentric shaft, and the top blade performs a rolling cutting motion due to different crank radii, offset, and different connecting rod lengths. This movement is guided by a slider. [Prior Art] Such a plate-like or side-trimming shearing system is known, for example, from German Patent No. DE 23 29 096 A1 or DE 25 10 881 A1. The double-sided trimming shears currently used are driven by the crankshaft and are immutable for the cutting motion system. The top blade carriage coupled to the eccentric shaft by a rigid connecting rod does not allow any type of modification of the hinge points. The curved blade performs a rolling cutting motion consisting of different crank radii, offsets, and lengths of the different connecting rods. The blade is guided in the cutting direction by a rotatably mounted slider. With this configuration, the thickness of the cut cannot be increased as desired. It is also impossible for the system to modify the cutting geometry. This means that the cutting motion of the top blade is always the same, so that the thickness of the metal sheet to be separated, for example, does not have any effect on the cutting process and cannot be considered. As such, the cutting thickness allowed by the machine is also limited to -5-200836863. On the other hand, the feed of the material is also determined by the thickness of the largest metal sheet, which makes it possible to have only one low-yield product in the case of a thin metal sheet. Therefore, the object of the present invention is to provide a modifiable The double-sided trimming shear of the cutting motion makes it possible to adapt to different cutting thicknesses, larger sheet metal thicknesses, and modifiable material yields. This object is achieved in accordance with the present invention by a double-sided trimming shear having a stationary bottom blade and a top that is driven by the connecting rod by means of an eccentric shaft that can be raised and lowered in a reduced manner. The blade, each connecting rod is disposed on its own eccentric shaft, and the top blade performs a rolling cutting motion due to different crank radii, offset and length of the connecting rod, the movement It is guided by a slider, wherein the length of the connecting rods is modifiable. This can be done in a variety of ways. For example, it is possible to subdivide each connecting rod by a nut/mandrel connection and the modification of the length of the connecting rod is effected by the relative rotation of the nut with respect to the mandrel. Another option is to have each of the connecting rods subdivided by a piston/cylinder connection and the modification of the length of the connecting rod is performed by the relative displacement of the piston with respect to the cylinder. Alternatively, each connecting rod may be subdivided by an eccentric link -6 - 200836863, and the modification of the length of the connecting rod is performed by relative rotation of the eccentric link. Thus, the core commemoration of the present invention is to modify the length of the connecting rods by loading a adjuster over its effective length. In one aspect, it is thus possible to modify the height of the top blade and to modify the depth of engagement by uniform adjustment. On the other hand, it is also possible to modify the top blade movement and to modify the cutting shape and cutting angle by uniform adjustment. This adjustment allows for compliance with different sheet metal thicknesses and material qualities. A considerable thickness of the metal sheet can also be cut by a rolling cut. For the purposes stated, the solution according to the invention thus allows cutting over a wide range of thicknesses. The compliance of the material feed is so likely 'in particular as a function of thickness that a higher yield can be achieved in the case of thinner metal sheets. [Embodiment] In these drawings, in each case, the crank driver is labeled 1 and the top blade is marked 2. These connecting rods are provided with reference numeral 3. Furthermore, the description or indication of the sliding guide 4 for the top blade 2 is shown in Figure 1 (as discussed), a nut/mandrel configuration is indicated and marked 5' for modifying the length of the connecting rod Regulator. In the top view of Fig. 1, the mandrel is retracted, and in the bottom illustration, the mandrel is extended. The illustration in Fig. 2 corresponds to this, and a piston/cylinder arrangement 6 is provided here as a regulator. Figure 3 illustrates the possibility of modifying the cutting geometry of the top blade by adjusting an eccentric adjuster, particularly for only one connecting rod. In detail, in FIG. 3, the eccentricity of the crankshaft is marked with 7, the rotation of the crank is marked with 8, and the rotation point of the crankshaft is marked with 1 4, the connecting rod on the crankshaft The rotation point is marked with 9, the actual length of the connecting rod is marked with 1 〇, and the effective connecting rod length that can be achieved by eccentric adjustment is marked with 1 1 (the rotation point of the connecting rod / the end of the connecting rod), and is used for The eccentric point of the minimum effective connecting rod length is labeled 1 2, and the eccentric point for the length of the maximum effective connecting rod is labeled 13 .
