  • the piston area of the fourth hydraulic piston is halved relative to the piston area of the third hydraulic piston when the fourth hydraulic piston travels twice the distance as the third hydraulic piston.
  • the third hydraulic piston is formed from a total of six individual pistons with a total area A G
  • the fourth hydraulic piston can consist of only three individual pistons with a total area A G / 2, if the individual pistons all have the same single piston area.
  • the first and third hydraulic cylinders are on the press ram attached, e.g. over an intermediate plate. Of the first punch is at one connected to the plunger Pressure piece arranged. As a result, both perform the first and third hydraulic cylinder and the first ram the same amount of feed movement.
  • the second die half, the second hydraulic cylinder and the fourth hydraulic cylinder are fixed to the frame opposite arranged on a base plate.
  • the hydraulic cylinders are via a pressure line with Pressure medium fillable.
  • FIGS. 1 and 2 respectively show the closed closing device with inlaid Blank 1a and the right side the closing device after completion of the Querfliesspressens.
  • the locking device shown in FIG. 1 has a vertically movable upper mold half and a frame-fixed Lower mold half on.

In the third hydraulic cylinder Z3, a third hydraulic piston K3 is guided on the radial circumferentially another compression spring 3 is arranged. At the first hydraulic piston K1 is at the intermediate plate. 6 facing away from the first die half M1 over a first die holder 12 attached. The first die half M1 is enclosed by a clamping ring 14. At the third hydraulic piston K3 closes a first Pressure element 16 on.
  • the lower mold half 4 consists of a frame-fixed Base plate 26, on which also frame-fixed the second Hydraulic cylinder Z2 (inside) and the fourth hydraulic cylinder Z4 (outboard) are arranged.
  • the hydraulic cylinders Z2 and Z4 are also a structural unit formed, between the hydraulic cylinders Z2 and Z4 a connection in the form of a channel 27 is present.
  • In the hydraulic cylinder Z2 is an axially movable second Hydraulic piston K2 out, where the second plunger S2 is arranged in the direction of the first plunger S1.
  • the second die half M2 is replaced by a second clamping ring 34 is enclosed and has a second Matrizenage 32, which acts as a pressure plate 35, fixed to the frame with the Construction unit of second and fourth hydraulic cylinder Z2, Z4 connected.
