Definitions
- the invention relates to a device for intermittent Driving a spindle for a workpiece holder, in particular a Forging machine, with a traction mechanism from an endless to a Drive wheel and a driven wheel guided traction means, with a continuous Rotary drive for the drive wheel and with a torsional vibrations exporting Superposition drive.
- the arrangement affects of the spring accumulator in the axial extension of the worm of Worm gear access to the spring elements of the spring accumulator, what the adjustment of the oscillation frequency of the superposition drive the hammering frequency of the forging tools by replacing the spring elements of the spring memory difficult.
- the invention is therefore based on the object, a device for intermittent driving a spindle for a workpiece holder, in particular a forging machine, of the kind described at the outset, that reduces the design effort and the adaptation of the rotationally oscillating Overhead drive to the respective requirements easier can be.
- the invention solves the problem posed by the fact that the superposition drive a rotationally displaceable about the axis of the driven wheel Carrier and mounted on the support pulleys for the respect having the drive wheel and expiring Wegstofftrume.
- the driven wheel By a back and forth rotation of the carrier thus the driven wheel is rotating shifted so that the continuous rotary drive of the drive wheel be superimposed with the help of the superposition drive torsional vibrations, which lead to an intermittent drive of the driven wheel.
- the for the intermittent drive of the driven wheel required torsional vibration the carrier about the axis of the driven wheel can in different ways be achieved according to the respective requirements, so that open advantageous customization options.
- the carrier for the pulleys in a simple manner to a spring store after a suggestion of a periodic detention of the driven over the spindle workpiece the intermittent Drive for the spindle by resonance-induced torsional vibrations of the carrier ensures.
- the carrier for the pulleys To drive via a vibratory drive, depending on the tool drive is controlled, which changes in the area of the tool drive an otherwise required adjustment of the spring accumulator superfluous power.
- traction means for the traction mechanism can ropes, belts or Chains are used. Particularly advantageous construction conditions However, arise when the traction mechanism as a toothed belt transmission is formed because with the timing belt a positive connection between the input and the output gear without special design effort is reached.
- the illustrated device for intermittently driving a Spindle 1 for a workpiece holder such as a chuck for a Forging workpiece, has a frame 2, in which the spindle 1 via bearings. 3 not only rotatable, but is also mounted axially displaceable.
- an actuating cylinder 4 To the axial Adjusting the spindle 1 is an actuating cylinder 4.
- a rotary drive 5 is provided, which is connected to the drive wheel 6 of a traction mechanism 7 is in drive connection.
- the driven gear 8 of the traction mechanism 7 sits on a hollow shaft 9, for example, as Dahlnutwelle for non-rotatable, but axially displaceable receptacle of the spindle 1 is formed.
- the spindle could be shifted axially with the rotary actuator 5.
- the traction mechanism 7 is connected to a superposition drive 10 to a Assembly summarized to the spindle 1 via the output gear. 8 to drive intermittently.
- a carrier 11 for two on both sides of the driven wheel 8 provided pulleys 12 provided over which the traction means 13 of the traction mechanism 7, in the Ausretevor, about the traction means 13 of the traction mechanism 7, in the embodiment a timing belt is endlessly guided, as is the case in particular Fig. 1 can be removed.
- the arrangement is made such that in a drawn in Fig. 1 center position of the carrier 11, the two pulleys 12 symmetrical to a common axial plane through the drive wheel 6 and the driven gear 8 of the traction mechanism 7 are.
- a spring 16th provided on the one hand on the frame 2 and on the other hand on an arm 17 of the Carrier 11 is articulated.
- This spring 16 which from the illustrated Can be stretched to the middle position shown in FIG. 1 to both sides, becomes when holding the blacksmith's work piece by the attacking him Forging tools stretched over the carrier 11 when passing through the continuous driven traction means 13, the guide rollers 12 with respect to the Spindle 1 held driven wheel 8 is rotated about the axis of the driven wheel 8 become.
- the stored energy in the spring 16 energy is used for turning back of the carrier 11, while the spindle 1 through the forging tools is released, so that for the carrier 11 a by the forging tools excited, torsional drive with the effect that the Spindle 1 in spite of the continuous rotary drive 5 synchronous to the Schmieder tools intermittently driven.
- the torsionally vibrating drive of the carrier 11 by no means needs to be done by a spring 16. It can be different Vibration drives are used, if only it is ensured that these Vibration drives controlled synchronously to drive the forging tools become.
