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, Round blank or the like Sheet metal parts, in the first stage pulling to Generation of the initial shape can be provided for further shaping can.
  • the invention relates to such multi-column presses with several, at least two press rams, the ram drive above the Press ram is arranged and where the force application is symmetrical to its central longitudinal axis.
  • press systems are for example from the publications 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 several press rams in the subsequent stages following the drawing stage as well as hissing trays after each processing stage.
  • Press assemblies are expensive with a correspondingly high number of components.
  • DE-A-26 57 911 describes a multi-column press for forming sheet metal parts, with press tables, Press stands and several press rams driven by a press drive known.
  • the gears to redirect the rotary motion of the motor drive of the press in an up and down movement of the press rams are above the force transmission in the plungers are arranged between a pair of stands. In the common pair of stands from two adjacent plungers, two gears are introduced, and the force is introduced into the Press ram is symmetrical to the tie rods.
  • the press system comprises a number of forming stages 4, 5, which in Press flow direction 6 - workpiece passage through the press system - follow each other.
  • Fig. 1 also shows tie rods 3, the corresponding Tie rod bushes the actual press stands 1 and 2 form.
  • the opposing press stands 2 point here each with tie rod 3 on (also Fig. 9), the centers of which according to Fig. 5 are on a common center line 17.
  • the press system also has according to Fig. 2 on crossbeams on the foundation attached press tables 7 and the motor drive 13 of the general with 12 positioned press drives via gears in gear boxes 14, 15 and connecting rods 18 up and down moved press ram 8, 9.
  • the motor drive 13 acts according to FIG. 4 on the gear boxes 14 and 15.
  • press ram 8, 9 bridge the otherwise existing Free space between the opposing press stands 2 and are separated by the differently designed gearbox in the Gear box 15 and the other, also in the intermediate stand area the press stand 1 or above it Gear 14 drivable.
  • the press rams 8, 9 are by means of crankshaft, toggle (Glenk), Eccentric gear and the like Gear means drivable.
  • the gears are in Gear boxes 14 and 15, respectively, between the press stands 1 and 2 or are housed above it.
  • tie rods are used 19 for fastening the gear box 15 to the press stands 2 or on side members rigidly connected to the press stands 2 intended.
  • the figures 7 and 8 allow a gearbox construction, here Recognize crankshaft transmission with the same tap for connecting rod 18, whereby a pair of connecting rods 18 on the press ram 8, a second pair of connecting rods 18 is articulated on the press ram 9.
  • the gear boxes 14 corresponding to that used in the gear box 15 Gearbox is designed. 5 leaves the symmetrical introduction of force 16 from the gearbox 15 or via the housed therein Recognize the gear in the press rams 8 and 9.
