  • the press body 50 is equipped with a blind flange for receiving a pressure cell. There are a total of two ports to the outside for an external, additional hydraulic module (shock surge generator) provide that can feed and remove hydraulic medium in the hydraulic press 38.
  • FIG. 10 shows a further variant of the second embodiment according to FIG. 4 of the device 10 according to the invention.
  • the movable body 16 has in the further variant of the second embodiment at both ends along the longitudinal axis 26 of the device 10 each have a support plate 64, wherein the extension of the support plate 64 perpendicular to the longitudinal axis 26 of the device 10 is greater than the cross-sectional diameter of the acceleration section 12th On each of both sides of each support plate 64, energy transfer elements 48 of the movable body 16 are arranged.
  • the illustrated embodiment of the device 10 according to the invention comprises four energy transmission sections 14, each energy transmission section 14 having energy transmission elements 60.
  • a press 38 is arranged on each energy transmission section 14.
  • the arrangement of two additional energy transmission sections 14 parallel to the acceleration section 12 and laterally spaced from its outer surfaces enables a double action of energy transmission in each direction of movement of the movable body 16.
  • the kinetic energy of the movable body 16 becomes simultaneous delivered via two separate power transmission sections 14.
