- a spindle drive provided with a drive control comprises spindle drive elements in the form of a drive spindle and a spindle nut mounted thereon, one of which being a spindle drive element on the motor side and the other being a spindle drive on the tool side.
- the motor-side spindle drive element by means of a drive motor relative to the tool-side spindle drive element rotatable about a spindle drive axis and thereby the tool-side spindle drive in the direction of the spindle drive axis and the tool storage in the direction of the lifting axis and wherein the tool-side spindle drive member by means of a drive motor rotatable about the spindle drive axis and thereby the tool storage is rotatable about the lifting axis.
- JP 04172133 A A punching machine of the above type is disclosed in JP 04172133 A.
- a rotary / lifting drive with two electric drive motors is provided for the tool storage of a punching machine. Both drive motors are arranged laterally next to a drive spindle, which in turn runs in the direction of a lifting axis of the tool storage.
- One of the drive motors is used for punching workpiece machining and is connected for this purpose via a belt drive with a seated on the drive spindle Hubspindelmutter.
- the second drive motor of the previously known punching machine is used for rotational adjustment of the tool storage or of the punching machine.
- Tool provided.
- this drive motor is drive-connected to a driver penetrated by the drive spindle.
- the present invention has set itself from the described prior art as the goal.
- a rotary / lifting drive with coaxial but opposite spindle drives is provided, which in turn are driven by separate drive motors.
- the motor-side spindle drive elements of the counter-rotating spindle drives can thereby be driven either in the same direction of rotation or in opposite directions of rotation. If the directions of rotation coincide with one another, then the motor-side spindle drive elements move jointly with the mutually coupled tool-side spindle drive elements about the spindle drive axis. With corresponding drive control of the counter-rotating spindle drives, in this way se the tool storage or the punching tool with the desired alignment about the lifting axis itch.
- the motor outputs of the individual drive motors are available in total. If the motor-side spindle drive elements run in mutually opposite directions, relative rotational movements result between the motor-side spindle drive elements and the associated tool-side spindle drive elements, which in turn cause a displacement of the tool-side spindle drive elements and of the tool support and the punching tool in the direction of the spindle drive axis or the lift axis. As a result of the coupling of the tool-side spindle drive elements complement each other in this case, the torques provided by the drive motors of the individual motor-side spindle drive elements.
- a correspondingly large force can be exerted in the direction of the lifting axis on the punching tool movably connected to the tool-side spindle drive elements.
- This large axial force can be used in particular as a punching force for workpiece machining.
- the engine power to be installed is lower than it would be if using an equally powerful single drive motor.
- With a corresponding rotational speed of the motor-side spindle drive elements rotating in opposite directions With a corresponding rotational speed of the motor-side spindle drive elements rotating in opposite directions, a rotation-free movement of the tool-side spindle drive elements in the direction of the spindle drive axis and thus a rotation-free movement of the punching tool in the direction of rotation can be achieved.
- tion of the lifting axis can be generated without requiring a separate rotation for the tool-side spindle drive elements would be required.
- This mode of operation of the counter-rotating spindle drives is selected for generating movements of the tool mounting and the punching tool in the direction of the lifting axis, in particular for the execution of working strokes of the punching tool.
- the rotational adjustment of the punching tool with respect to the stroke axis may be important. Under certain circumstances, it must be ensured that the punching tool runs with a specific rotational position relative to the lifting axis onto the workpiece to be machined. By means of the drive control of the counter-rotating spindle drives according to the invention, this can be ensured. As shown in claim 3 actual rotational settings of the tool storage with respect to the lifting axis are detected.
- the rotational speed of at least one motor-side spindle drive element can be controlled and in this way the rotational adjustment of the tool storage can be influenced. It is conceivable, for example, that when starting the oppositely driven motor-side spindle drive elements, a slight change in the rotational position of the tool storage or the punch results that the rotational adjustment of the tool storage or the punching tool but not changed after the startup phase. Is such a change in the rotational adjustment of tool storage and Punching tool for the workpiece machining to be performed without meaning, so it can be maintained. In this case, the rotational speed of the motor-side spindle drive elements reached after the start-up phase is to be kept at a constant value by means of the evaluation and control unit of the drive control.
- an adjustment of the punching tool about the lifting axis can be reversed during the movement of the punching tool in the direction of the lifting axis.
- This circumstance is especially important when punching tools are used with a deviating from the circular cross-sectional shape.
- the rotational position of the punching tool with respect to the lifting axis for the machining result or for the feasibility of punching workpiece machining is of crucial importance.

- the rotary brake device supports the counter-rotating spindle drives, which, if appropriately controlled, also have an uncon- wanted to counteract adjustment of the tool storage in the direction of the lifting axis. Since the rotary braking device therefore has to apply only a relatively small force to prevent rotation of the tool storage, it can build small. Regardless of the rotary braking device thus results in a compact design of the rotary / lifting drive according to the invention.
- opposing spindle drives are provided with a uniform translation in a further embodiment of the invention.
- This unification of the drive components requires a structurally simple construction of the overall arrangement and also simplifies the drive control of the counter-rotating spindle drives.
- the invention types according to claims 9 to 11 are characterized by a particularly compact design of the rotary / lifting drive and thus the entire machine. Due to the inventive features of claim 9 results for the rotary / lifting drive relatively small dimensions in the radial direction of the spindle drive axis. Accordingly, the rotary / lifting drive according to claim 10 is relatively small in the direction of the spindle drive axis. Torque motors, as mentioned in claim 11, allow it to transmit even high engine torques without installation space requiring intermediate gear.
- the one-piece design of the tool-side spindle drive elements according to claim 12 is provided in the interest of minimizing the number of items and thus in the interest of a structurally simple and compact structure of the overall arrangement.
- a preferably pneumatic biasing device is provided in the direction of the spindle drive axis for the tool-side spindle drive elements according to the invention punching machines.
- Such biasing devices increase the life and reliability of the rotary / lifting drive inventive punching machines.
- the biasing device counteracts a sudden load change on the rotary / lifting drive. With an appropriate choice of bias results in a less wear causing swelling stress of the spindle drive instead of changing stress.
