Definitions

  • the invention relates to a method for operating a press according to claim 1 or 2 and a press according to claim 10.
  • a servo-press is known in which the selection or determination of a movement sequence is influenced by the ram kinematics, e.g. the downward speed of the plunger or the
  • Upward speed of the plunger is changed to facilitate a parts transport.
  • the inventive method for operating a press with at least 80% of its nominal pressing force, in particular a
  • Crank press for forming, in particular for forging workpieces such as in particular a forge-crank press, provides, the press with a servo drive and an arranged between the servo drive and a workpiece, in operation to equip the press moving mass system, wherein a mass of the mass system is formed at least by a plunger and at least by a drive shaft, wherein the mass system at least temporarily by the servo drive
  • Servo drive is accelerated before the forming process such that at least 100% of the nominal pressing force are available during the forming process. This makes it possible to dimension the servo drive in its maximum power compared to a maximum nominal press force of the press too small.
  • the mass system is at least temporarily driven by the servo drive, wherein the increased nominal pressing force is provided proportionately by the servo drive and the mass system and wherein the difference between 80% nominal force and at least 100% nominal force by increasing the speed of the mass of the mass system and / or compensated by an increase in the mass of the mass system.
  • the method provides, the mass system its output in the forming process energy up to a
  • crankshaft is driven and wherein from the servo drive to the crankshaft outside and during the forming process at most a torque is applied, which is at least 20% smaller than the torque at 100% nominal force.
  • the servo drive and its inverter can be significantly smaller
  • Servo drive and proportionally transform under release of kinetic energy of the mass system This makes it possible to dimension the servo drive in relation to the nominal power of the press small.
  • the servo drive provides a maximum of 80% of a nominal pressing force of the press for a forming process and that the
  • Servo drive at least 20% of the nominal press force of the press for the forming process provides. This makes it possible to make a undersizing of the servo drive with respect to its maximum power with respect to a nominal pressing force of the press. This will be the
  • Figure 1 a diagram in which for a press a
  • Plunger is in top dead center
  • Figure 2 a diagram in which for. the press again the speed of the servo drive is removed above the position of the plunger, wherein the press continues from a position in which - in continuation of the sequence shown in the first diagram - the plunger passes the top dead center at a speed of 10 U / min ,
  • FIG. 1 shows a diagram D1 in which for a press a speed DZ of a servo drive indicated in revolutions per minute is plotted over a position ST of a plunger, the press starting from a position I in which the plunger is at top dead center OT1 stands. From standstill, the speed DZ of the servo drive is continuously increased to 75 ü / min, in which case a kinetic energy contained in a mass system downstream of the servo drive builds up and increases. From one
  • Servo drive provided energy also in the
  • Mass system stored energy is needed. Thereafter, the speed DZ of the servo drive continues to decrease, because using the servo drive energy recovery occurs to ensure a sufficient time window for a parts transport and a caretaker of the die.
  • the servo drive is operated as a generator.
  • the mass system will depend on one Position III of the plunger - even before it reaches the top dead center OT2 - fed by increasing the speed of the servo drive energy again.
  • Diagram D2 how the ram passes top dead center 0T2 at the beginning of a second cycle at a speed of the servo drive of 10 rpm and thus already energetic.
  • the servo drive then rotates up again to a speed of 75 rpm, thereby further increasing the kinetic energy of the mass system.
  • the following, further sequence is similar to that described for the figure 1 further sequence.
