Definitions

  • the starting position is formed by a trapezoidal stop 8.
  • a pin-shaped extension 10 of the stop 8 is clamped in a recess 12 in the frame.
  • the plunger is moved in the direction of action (arrow D) by activating the electromagnetic drive units.
  • the pressure ram is returned to its starting position by the force of the springs 7. It is particularly advantageous if the tension springs 7 run on the inclined surfaces of the trapezoidal stop 8 that rise in the direction D, since their natural vibrations are damped when they are applied to the stop 8.
  • the starting position can also be brought about by a cylindrical damper (not shown) which is screwed into a threaded sleeve which is arranged in the pressure direction within a bead at the base of the U-shaped frame.
