Definitions

  • the invention relates to a multi-column press or the like.
  • Press system for forming sheet metal parts with opposing press stands. Press systems of this type are used to form a blank, blank or the like. Sheet metal parts, in the first stage the drawing for generating the initial shape can be provided for the further shaping.
  • the invention relates to such multi-column presses with a plurality of, at least two press rams, the ram drive being arranged above the press ram and in which the force is applied symmetrically to its central longitudinal axis.
  • press systems are known for example from US-A-4,102,174; DE-C2-31 18 955; DE-A1-39 05 068 and DE-A1-41 24 083 known.
  • the latter publications show the use of several press rams in the subsequent stages following the drawing stage, as well as hissing deposits after each processing stage.
  • These press assemblies shown here are expensive with a correspondingly high number of components.
  • the drive of two abutting, (subsequent) press rams should take place from an intermediate stand area.
  • the press system comprises a number of forming stages 4, 5, which follow one another in the direction of press travel 6 - workpiece passage through the press system.
  • Fig. 1 also shows tie rods 3, which form the actual press stands 1 and 2 with corresponding tie rod bushings.
  • the opposing press stands 2 each have a tie rod 3 (also FIG. 9), the centers of which are located on a common center line 17 according to FIG. 5.
  • the press system also has, as shown in FIG. 2, press rams 7, which are placed on the foundation by means of cross beams and the press rams 8, 9 which are moved up and down by the motor drive 13 of the press drive, which is generally positioned with 12, via gears in gear boxes 14, 15 and connecting rods 18. 4 acts on the gear boxes 14 and 15.
  • tool halves 10, 11 are each oriented on press table 7 or press ram 8, 9.
  • the Press rams 8, 9 shown bridge the otherwise existing space between the opposing press stands 2 and can be driven separately via the differently designed gears in the gear box 15 and the other, also in the intermediate stand area of the press stand 1 or above the gears 14 located there.
  • the press rams 8, 9 are by means of crankshaft, toggle (Glenk), eccentric gears and the like. Gear means drivable.
  • gears are located in gear boxes 14 and 15, respectively, which are accommodated between the press stands 1 and 2 or above them.
  • tie rods 19 are provided for fastening the gear box 15 to the press stands 2 or to longitudinal beams rigidly connected to the press stands 2.
  • the figures 7 and 8 show a transmission structure, here a crankshaft transmission with the same tap for connecting rods 18, one connecting rod pair 18 being articulated on the press ram 8, a second pair of connecting rods 18 being connected to the press ram 9.
  • the gear boxes 14 are designed in accordance with the gear used in the gear box 15. 5 shows the symmetrical introduction of force 16 from the gear box 15 or via the gear housed therein into the press rams 8 and 9.
