    The invention relates to a forging apparatus with centrally symmetrically arranged around a forging axis forging tools whose radially guided in a frame tool carrier are each connected to a lift drive, and with a common drive for the Hubtriebe.
    Forging with symmetrically arranged around a forging axis forging tools, which are usually diametrically opposite each other with respect to the forging axis, have different Hubtriebe for the forging tools on. For example, it is known to associate an eccentric shaft drive with each tool carrier guided radially displaceably in a frame with respect to the forging axis, wherein the eccentric shafts are synchronized via a common spur gear. The advantage of these eccentric shaft drives, namely to realize large forging forces at high impact rates, is offset by the disadvantage of a large design effort. If synchronized hydraulic drives are used as lift drives, the result is a simpler design, but the achievable beat numbers remain limited. Another drive for the relative to the forging axis radially guided in a frame tool carrier comprises for each forging tool cam output with a common drive in the form of a coaxially mounted to the forging axis cam wheel, which is continuously driven, so that the actuating cam of the revolving cam the tool carrier with a corresponding stroke apply. Disadvantages are the difficult lubricating conditions as well as limited forging forces. -2-
    The invention is therefore an object of the invention to provide a forging device that can provide large forging forces at high speeds, with relatively simple design means.
    Starting from a forging device of the type described above, the invention solves the problem by the fact that the lifting units each have a abutment on one hand on a housing and on the other hand on the tool carrier pivotally abgestützes connecting rod and that the common drive for the Hubtriebe a torsional vibration drive for at least one order Forged axle rotatably mounted actuator for one of the two abutment of the connecting rod comprises.
    Due to the design of the lift mechanisms with a connecting rod supported on a housing on the one hand and on the other hand on a tool carrier, advantageous design requirements for the application of large forging forces arise when the connecting rods are rotationally driven in the extended position with the radially guided tool carriers. For this purpose, only one of the two abutments of the connecting rod need to be displaced, which leads to structurally simple drive ratios, if at least one actuator for the connecting rods of the Hubtriebe is provided which is rotatably mounted about the forging axis and offset by means of a torsional vibration drive in torsional vibrations can be so that the connecting rods of the Hubtriebe are synchronously pivoted about the actuator with the result that the tool carrier are driven in the radial direction with respect to the forging axis. The stroke rate depends on the frequency of the torsional vibration drive, which can be set correspondingly high. In order to ensure a mass balance, it may be advantageous to provide two oppositely rotating oscillating drivable actuators for the common driving the lift mechanisms for the forging tools.
    Particularly advantageous gear ratios for the applied forging forces arise when the connecting rods form a toggle joint with the associated, guided in the frame radially to the forging axis tool carriers. In this case, particularly favorable design conditions arise when the frame is • · > Or the housing, the actuator of the common drive for the....... * Hubtriebe forms and when the torsional vibration drive between the housing and the relative to the housing about the forging axis rotatably mounted frame is provided. The mutual rotation of the frame and housing causes a corresponding action on the toggle joint and thus the desired drive of the forging tools.
    Another way to drive the connecting rods to oscillate, characterized in that the actuator of the common drive for the Hubtriebe is designed as a rotatably mounted around the forged axis collar with radial sliding guides for the tool carriers associated abutment of the connecting rod and that between these abutments and the In the housing-fixed frame guided tool carriers sliding body are provided for pressure transmission. Such a design of the common drive for the individual lifting drives allows a housing-fixed arrangement of the frame for guiding the tool carrier, because a separate adjusting ring is provided for the connecting rods. The necessary in the drive of the connecting rod in the sense of torsional path compensation between the radially outwardly guided in the collar abutments and the associated tool carriers is ensured by arranged between the abutments and the tool carriers slider, which serve for pressure transmission from the connecting rods to the tool carrier. In order to ensure the installation of these sliding body on the abutments or the tool carriers with simple design means even when Rückstellhub, the tool carrier can be acted upon in the sense of a system on the abutments of the connecting rod on the slider with a restoring force.
    As a torsional vibration drive for the rotatably mounted about the forging axis actuator different drives can be used. A particularly simple design of the torsional vibration drive, however, results when the torsional vibration drive is designed as an eccentric shaft drive.
    To adjust the stroke position of the forging tools, the tool carriers can be provided in a known manner with a device for the radial adjustment of the tools.

Due to the design of the lift mechanisms with abutments of the housing supporting connecting rods, there is the additional possibility that the connecting rods supporting the abutment are mounted radially adjustable in the housing with respect to the forging, so that this radial displacement of the abutment for the connecting rod and the Hublage the lift mechanisms formed by the connecting rod changes. On the stroke position of the forging tools but can also be influenced by a change in angle of the vibration range of the connecting rod. For this purpose, the eccentric shaft of the eccentric shaft drive can be mounted radially adjustable.
    Thus, successive pairs of tools beat alternately from the pairwise diametrically opposed forging tools, the connecting rods in a middle stroke position of the Hubtriebe for the pairwise opposite tool carrier pairs alternately in opposite directions with respect to the tool carrier inclined. This means that when a pivoting of the connecting rod in a circumferential direction, a connecting rod a working stroke and the oppositely inclined connecting rod perform a return stroke.
    In the drawing, the subject invention is shown, for example. Show it
    1 shows a forging device according to the invention in a schematic, simplified axial normal section,
    2 shows this forging device in a section along the line II-II of FIG. 1 on a larger scale,
    3 shows a variant of a lifting drive for a tool carrier in a section perpendicular to the forging axis on a larger scale, and FIG. 4 shows a representation corresponding to FIG. 1 of a construction variant of a forging device according to the invention.
    As can be seen from FIGS. 1 and 2, the forging device has a housing 1 and a housing 1 rotatably mounted about a forging axis 2 • * • · · «- 5
    Gesteli 3, which receives 2 radially guided tool carrier 4 with respect to the forging axis. These tool carriers 4 are equipped according to FIG. 2 with forging tools 5, which are connected via wedge gear 6 for adjusting the stroke position of the forging tools 5 to the tool carriers 4. To act on the forging tools 5, the tool carriers 4 are associated with 4 lifting drives 7, each of which has a connecting rod 8 which is pivotally supported via abutments 9, 10 on the one hand on the associated tool carrier 4 and on the other hand on the housing 1. Thus, if the frame 3 is rotated relative to the housing 1, the abutment 9 are also relative to the abutments 10 with respect to the forging axis 2 rotated with the result that the tool carrier 4 are displaced radially in the frame 3. Since a torsional vibration drive 11 is provided between the housing 1 and the frame 3, the frame 3 is rotationally driven as an actuator 12 for the lifting drives 7, for example, in a rotatably held housing 1, so that the tool carrier 4 are acted upon by working and restoring strokes. As a torsional vibration drive 11 an eccentric shaft drive with an eccentric shaft 13 is provided in the embodiment, the eccentric 14 acts on the actuator 12 via a sliding block 15. To drive the eccentric shaft 13, a pulley 16 is provided in FIG.
    According to Fig. 3, the housing 1 associated abutment 10 can be adjusted radially with respect to the forging axis 2, via a respective hydraulically actuated piston 17, which is not mandatory, because a mechanical displacement of the abutment 10 is the task of Setting the stroke position of the tool holder 4 and thus the forging tools 5 triggers.
    4, a forging apparatus is shown, in which the frame 3 is held in the housing 1 in a rotationally fixed manner. It must therefore be the tool holders associated abutment 9 radially slidably mounted in an actuator 12, which is designed as a coaxial with the forging 2 rotatably mounted in the housing 1 collar 18 and connected to a trained example as Exzenterwellenantrieb torsional vibration drive 11, as this is based on the embodiment was described in more detail according to FIG. 1. The abutment 9 of the connecting rod 8 therefore carry out radial working and return strokes in the case of a rotationally oscillating drive of the steep ring 18. The tool carriers 4 are connected to the abutments 9 in the exemplary embodiment of the abutments 9 associated sliders 19 so that the abutment 9 can move relative to the tool carriers 4 even with a pressurization of the tool carrier 4 via the sliders 19 in the circumferential direction of the adjusting ring 18. Thus, the system of the workpiece carrier 4 is ensured on the slides during the Rückstellhubs the Hubtriebe 7, the tool carrier 4 are applied in the sense of a contact with the abutments 9 of the connecting rod 8 via the slider 19 with a restoring force. For this purpose, the tool holder 4 are based for example on annular piston 20 on the frame 3, which are acted upon by a corresponding return pressure.
    The invention is of course not limited to the illustrated embodiments. Thus, the eccentric shaft 13 of the eccentric shaft drive could be displaced radially to adjust the stroke position or the hub. By a radial displacement of the eccentric shaft 13 with respect to the forging axis 2 influence on the swinging width of the connecting rod 8 is taken. If the eccentric shaft 13 is displaced in the direction of the torsional vibrations of the actuator 12, then the center position of the connecting rod 8 and thus the stroke position of the tool carrier 4 is changed.
