Definitions

  • the invention relates to a multi-column press, a stage or multi-stage press, a hybrid press system or the like.
  • a drawing stage with press ram drive and drawing apparatus can be provided. Press systems of this type are used to form a blank, blank or the like. Sheet metal parts, with the drawing in the first stage being able to produce the initial shape for further shaping.
  • the invention also relates in particular to areas, the areas which are generally designated with subsequent stages and in which the preformed sheet metal part is given its final shape.
  • the invention also relates to presses in which the ram drive is arranged above the press ram and so the force is introduced into the center or in the peripheral areas of the press ram.
  • the invention thus relates to press systems with a mechanical or hydraulic drive.
  • Such 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 last-mentioned DE-A1-39 05 068 and DE-A1-41 24 083 show the use of split press rams in the subsequent stages as well as clipboards after each processing stage.
  • the press designs which are expensive due to such measures, are cheaper; the total number of components, the material consumption and thus the investment costs for the user must be significantly reduced.
  • the invention treads new paths, which are carried out individually and are inventive in combination.
  • press ram and press table each represent a one-piece structure for the operating state, for transport and assembly can consist of several interconnectable frame parts and individual parts.
  • a large number of force introduction points are eliminated compared to the previous use of e.g. five press rams at 5 subsequent stages with up to 20 connecting rods.
  • FIG. 1 show the installation site of a press system with a drawing stage 1, which can also be used as a single press. Subsequent stages of a three-column press, which here have two and three, five working stages in total, are identified by the number 2. The ranges of press stands are indicated by 6. It can be seen that a stand is designed with a double tie rod 13. Instead of a tie rod with a larger diameter per stand area 6, e.g. for the middle of three stand areas 6, over which a press ram 7 (FIG.
  • a multi-column press is shown as a subsequent stage press, the upstream drawing press with the drawing stage 1 can also be omitted.
  • This multi-column press with, for example, three press columns - column regions 6 - is set up on the foundation side, cross members 4 extending across the width of the multi-column press.
  • 3 press tables are positioned, which are firmly placed on the cross members 4, which can be made in one piece and carry the sliding tables with tools 8.
  • the upper parts of the tool are fastened to the press ram 7, which is in one piece during operation.
  • the press stands 6 are connected in front of and behind the press ram 7 by longitudinal members 5.
  • Gear boxes 11 are placed in the area above the press stand 6.
  • the gear boxes 11 serve to accommodate motion deflection means, possibly also e.g. Hydraulic drive means for the up and down movement of the press ram 7.
  • the means in the drive boxes 11 are driven by motors 11, a flywheel 19 and a driven shaft 20 outside the gear boxes 11, as shown in FIG. 4.
  • the press ram 7 is driven here in three planes corresponding to the number of stand areas 6 via connecting rods 17 which are led out downward from the drive boxes 11.
  • a transfer device 9 for the transport of the sheet metal parts in the stages in the press pass is passed through the press system.
  • tie rods 13 in the central stand area 6 can be seen.
  • the tie rods 13 as a whole are handled by tie rod sleeves 14 for support, dimensional accuracy and force absorption.
  • 5, the press ram 7 is mounted in longitudinal or linear bearings 23 such that it can be raised and lowered.
  • the introduction of force, point of application of the connecting rods 17 on the press ram 7, is identified by circles 18.
  • the drive box 11 shows one of several drive boxes 11, here the drive box 11 arranged in the central region of the press ram 7.
  • the drive box 11 is placed above the press stand 6 on the longitudinal beams 5 extending in front of and behind the press ram 7 and via four tie rods 22 with tie rod sleeves attached.
  • the figures 7 and 8 show drive means moved by the main shaft 20 (FIG. 4), including a connecting rod 17 with the force introduction 18 into the press ram 7.
  • the centers of the tie rods 13 of a pair of stands 12 and the center of the force introduction 18 - connecting rods 17 - in the press ram 7 lie on a common line 16. Both of the tie rods 13 required here lie on this common line 16 for the middle force introduction 18.
