Definitions

  • the present invention relates to a drive device for a forming machine, in particular a forming press, and a forming machine.
  • a drive device regularly comprises a drive motor, for example an electric motor, an energy store, for example a flywheel, and a transmission, for example a planetary gear.
  • a drive motor for example an electric motor
  • an energy store for example a flywheel
  • a transmission for example a planetary gear.
  • the flywheel provides a considerable part of the deformation energy which is required in the actual forming process.
  • the inertial mass of the flywheel can also be a hindrance, for example when the forming machine has to be braked or accelerated for other reasons, in particular for providing a predetermined speed profile. Such a process is always associated with a loss of energy.
  • a pressing device with a main drive which is designed as a rotary direct drive, an eccentric, a connecting rod and at least one press ram arranged thereon is known from WO 2004/056559 known.
  • any additional flywheel in the drive train of the press drive is omitted and an electric motor selected as a direct drive.
  • the high moments or forces provided by the direct drive proposed here enable a direct coupling with the eccentric, the connecting rod and the press ram arranged thereon. This saves gear, flywheel mass, clutch and brakes.
  • drive devices for presses which are designed as so-called direct drives without flywheel, come only for comparatively small press performances in question or a considerably more powerful or stronger torque main drive motor must be selected, as is the case with drive units with flywheel, which ultimately results in high costs.
  • a drive device with the characterizing features of claim 1.
  • Characterized in that it is the drive motor is an electric motor, wherein it is a planetary gear in the transmission can be provided a space-saving, and low-maintenance drive means for a forming machine. Due to the lack of flywheel can be a more precise control of the forming machine, since the forming machine can be quasi "directly” controlled and almost no momentum masses would have to be accelerated or decelerated. In addition, much higher torques can be provided by the planetary gear, as would be possible with an electric motor as such. Furthermore, the planetary gear allows an extremely compact design of the entire drive device. Also has such a drive device on a comparatively little to no backlash.
  • the axis of rotation of the planetary gear and the axis of rotation of the drive motor are congruent.
  • the direct series connection of drive motor and planetary gear results in an extremely compact design.
  • the drive motor is a servo motor.
  • the servomotor is highly dynamic and it can be approached any angular positions, so that such a drive motor is particularly suitable for a drive device for a forming device.
  • the drive motor is a drive motor with a hollow shaft as the output shaft, wherein the transmission is at least partially mounted within the hollow shaft.
  • the drive motor is a torque motor with a hollow shaft as the output shaft, wherein the transmission provided at least in sections within the hollow shaft is a planetary gear.
  • Another object of the present invention is to propose a forming machine, in particular a forming press, which is characterized by a space-saving design and the possibility of precise control of the press ram with the introduction of a high torque, at comparatively low power of the drive motor.
  • this object is achieved by a forming device according to claim 7. Characterized in that a drive device according to one of claims 1 to 6 is provided for the forming device, the advantageous properties of the inventively proposed drive means for the forming device can be exploited.
  • the forming machine has a ram drive with a Rädervorgelege and a crankshaft, wherein the drive shaft of the Rädervorge privileges has an axis of rotation, wherein the axis of rotation of the drive shaft coincides with the axis of rotation of the planetary gear and the axis of rotation of the drive motor.
  • the axis of rotation of the planetary gear, the axis of rotation of the drive motor and the axis of rotation of the crankshaft are congruent. This also results in a low backlash and a small space.
  • An inventive press drive essentially comprises a drive motor 1 and a transmission 2, but no flywheel as in the prior art usual.
  • a press essentially comprises a drive motor 1 and a transmission 2, but no flywheel as in the prior art usual.
  • the transmission 2 is a planetary gear and accordingly comprises a central sun gear, a planet carrier with planetary gears, and a ring gear.
  • the masses of the rotating bodies involved such as the components of the planetary gear or the rotor of the electric motor develop a mass moment of inertia. These moments of inertia must inevitably be accepted. All energy should preferably be provided exclusively by the electric motor used. Accordingly, it is now possible to fully utilize the entire dynamics of the electric motor for driving a forming machine. For example, very variable speed profiles can be provided by the drive device according to the invention. Also, a reversal of rotation take place without the need for a complex reversal within the transmission. Overall, without the interposition of a flywheel and by the direct drive of the electric motor considerable advantages in terms of the possibilities for a variable drive a forming device.
  • the aforementioned components are arranged around the rotation axis of the sun gear.
  • the dot-dash line 8 can be seen that both the drive axis of the drive motor, as well as the axis of rotation of the transmission 2 coincide. Accordingly, there is an advantageous torque transmission between the drive motor and the transmission.
  • the drive motor is a servo motor.
  • the servomotor is a motor that can approach various predefinable positions and then retains them.
  • the position is an angular position in the case of a rotary motor.
  • the drive motor is a so-called torque motor 9.
  • Fig. 3 a corresponding drive concept is shown.
  • a torque motor is a torque motor having an annular geometry with a hollow shaft 11 as the output shaft.
  • a torque motor 9 is particularly suitable as a direct drive, which can apply large torques at low speeds. Its applications are, however, according to the above-mentioned prior art, not in the field of press drives, but rather in the field of machine tools with rotary tables or swivel axes, so for example in high-speed cutting machining centers or form milling with swivel heads in large-scale machining centers.
  • a torque motor 9 as part of the drive means for a forming machine, in particular a press drive, in particular the transmission, preferably a planetary gear 10 to accommodate within the designed as a hollow shaft 11 output shaft of the torque motor 9, resulting in a particularly space-saving embodiment of a press drive can result ,
  • the servomotor compared to a torque motor, generally has a lower torque relative to the required installation space, the servomotor is highly dynamic and any desired angular positions can be approached.
