    Description: The invention relates to a press for producing fineblanked parts.
    The manufacturing process for the production of fineblanking parts as well as the presses used in this case are known in the art in principle.
    By means of fineblanking cutting parts can be made very high quality and with very small tolerances. In order for the plastic forming process to run in a controlled manner and to avoid undesirable changes such as cracks in the material structure, tools with several tool parts are used for fineblanking. These tool parts each have specific functions and are controlled individually via drives in order to apply the corresponding cutting, serration and counter-holding forces.
    The disadvantages of the presses in the prior art are that they have a very limited stroke rate depending on the workpiece and the installation space of the tool parts is limited to a press table size of about 1.1 m x 1.1 m. Although there are known presses in which several tools are used together on a press table. However, this is possible only with considerable additional effort by the central arrangement of the cushion axes in the press table. Regardless of the number of tools used, however, a large number of drives is necessary in order to control the individual tool parts.
    The object of the invention is to provide a press for the production of fineblanking parts with a larger, usable press table size and a reduced number of required for driving the tools drives and thus a more cost-effective, more flexible press.
    To solve the problem, a press is provided for the production of fineblanking parts, with a tool holder, a traverse and a tool with multiple tool parts, wherein the tool has a tool block. The tool holder comprises a set of transmission means, wherein the traverse is drivingly connected via the set of transmission means with at least a plurality of required for the production of a fine cutting part, arranged in the tool block tool parts and wherein the traverse is driven by at least two traverse drives.
    In the context of the invention, a tool part is a part of the tool, which has a specific, in particular limited to one area function and / or can be controlled independently of other parts of the tool. By operating several tool parts via a traverse, the number of drives required for driving the tool parts can be reduced to a few traverse drives that actuate the common traverse. The traverse can be performed rigid, whereby the control of tool parts over a length of well over 1 m is possible, which significantly larger press table sizes can be provided.
    The press may comprise a second tool holder and a second cross member, and the tool may comprise a second tool block, the second tool holder having a second set of transmission means, the second cross member via the second set of transmission means with at least several of the Manufacture of a fine cutting part required, arranged in the second tool block tool parts is drivingly connected and wherein the second traverse is driven by at least two traverse drives. By means of this construction with the second tool holder, which is arranged in particular opposite the first tool holder, and the second traverse, the number of drives required for driving the tool parts can be further reduced.
    According to an advantageous embodiment, the first traverse on the first set of transmission means is drivingly connected to all arranged in the first tool block tool parts, which apply a ring-tooth force and / or a counter-holding force on a workpiece, and / or the second traverse is on the second Set of transmission means with all arranged in the second tool block tool parts drivingly connected, which apply a ring-tooth force and / or a counter-holding force on a workpiece. This has the advantage that all tool parts that apply a ring-tooth force and / or a counter-holding force to a workpiece, can be jointly controlled via their respective assigned traverse and pressurized, and thus less drives for driving the tool parts required.
    According to a further advantageous embodiment, the first traverse on the first set of transmission means with all required for the production of a fine blanking part, arranged in the first tool block tool parts is drivingly connected and / or the second traverse is on the second set of transmission means with all for the production a fine cutting part required, arranged in the second tool block tool parts drivingly connected. In this way, all the tool parts can be controlled together via their respective associated Traverse and pressurized, whereby the required number of drives for driving the tool parts is minimized.
    It is advantageous if each required for the production of a fine blanking tool part is drivingly connected to a respective transmission means. In this way, the transmission means can be adapted to the tool part and its function and, for example, have a certain length to perform its function at a certain time.
    Preferably, the transmission means are pressure pins, since they allow a direct and effective power transmission, have a long service life and are inexpensive.
    The first and / or the second tool holder has, for example, a plurality of receptacles for pressure bolts, in particular more receptacles are provided, as are required for the production of a fine blanking part. In this way, the pressure bolts can be arranged according to the requirements of various tools, whereby the press is provided for a variety of different tools and can be used flexibly.
    Preferably, each traverse is controlled by at least two and preferably not more than three truss drives. The reduction in the number of truss drives to only two or three traverse drives, represents a further optimization in terms of efficiency and cost.
    In an advantageous embodiment, the truss drives the first cross member and / or the truss drives of the second cross member are each force-controlled with each other. In this way, each traverse forms a hydraulic balance, whereby each Traverse exerts a homogeneous pressure on the transfer means over its surface.
    In a further advantageous embodiment, the truss drives the first cross member and / or the truss drives the second cross member are each driven by a single drive unit. By driving a plurality of truss drives together via a drive unit, the number of required drive units is reduced, which reduces the manufacturing costs of the press.
    Preferably, the truss drives the first traverse and the truss drives the second traverse are driven by a single drive unit. By driving all traverse drives together via only one drive unit, the number of drive units required is minimized and the cost of the press is further reduced.
    The press is for example a servo-operated toggle press, which in particular comprises a operated by at least one drive unit 2-toggle lever system.
    According to an advantageous embodiment, the press has a maximum pressing force of 1500 kN, preferably 1100 kN, and / or a press table length of up to 4.0 m, preferably of up to 3.5 m. This embodiment offers a particularly good. Cost-benefit ratio and allows a high number of strokes and a good waste and Teilausbringung.

To produce a fine blanking part, the workpiece 23 is introduced into the press 10 between the first and second tool blocks 18, 20 when the press 10 is open, and rests there on the first tool block 18. In the next step, as shown in Fig. 2, the second tool block 20 from above on the first tool block 18 opposite side of the workpiece 23 is placed by the second tool holder 14 is lowered in the machine frame 13. In the following step, which is shown in Fig. 3, the first and second traverse 24, 30 are moved via the respective truss drives 36, 37 each from a first position to a second position. By means of the transmission means 28, the corresponding, with these drivingly connected tool parts 22 are moved and / or subjected to a pressure to apply depending on the function of the corresponding tool part 22 a Zigzag, a counter-holding and / or a cutting force on the workpiece 23. By the ring-tooth force, the workpiece 23 is held in position. The tool parts 22, which are intended for the cutting, apply a force to the workpiece 23, which leads to the separation of the workpiece 23 at the cut edges 44 formed by individual transitions of different tool parts 22, while the counter holding forces prevent an undesired deformation of the workpiece 23 and so a controlled cut is ensured. In this way it is ensured that the fineblanked parts produced have a high quality and low tolerances.
