Definitions

  • the invention relates to a multi-column press according to the Preamble of claim 1.
  • a Drawing stage with press ram drive and drawing device can be provided be. Presses of this type are used to form a blank, Ronde or the like. Sheet metal parts, in the first stage pulling to Generation of the initial shape can be provided for further shaping can.
  • Such presses are for example from the publications US-A-4,102,174 (state of the art); 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 also show and DE-A1-41 24 083 the use of split press rams in the Subsequent stages as well as clipboards after each processing stage.
  • the expensive press designs are cheapen; the total number of components, the material consumption and thus the investment costs for the user are clearly increasing reduce.
  • the invention breaks new ground for this.
  • press ram as also press table for the operating state, each in one piece Represent structures for transport and assembly from several interconnectable frame parts and individual parts can exist. A large number of force introduction points are eliminated earlier use of e.g. five press rams with 5 subsequent stages up to 20 connecting rods.
  • the Power redirection significantly minimized.
  • the drive boxes are open Width of required waste chutes reduced.
  • the width of the stand area could be reduced significantly.
  • Fig. 1 show the location of a Press system with a drawing stage 1, which can also be used as a single press can be set. With the number 2, subsequent stages are one Three-column press featured, here two and three, in total has five working levels. With 6 are the areas of press stands specified. It can be seen that a stand with a Double tie rod 13 is executed. Instead of a tie rod larger Diameter per stand area 6 are e.g. for the middle of three stand areas 6, over which a press ram 7 (FIG. 2) extends, two tie rods 13 each with a substantially reduced cross section arranged.
  • Opposing stands or areas of stands 6 form a pair of stands 12. With 21 waste chutes are numbered, which extend across the width of the press room and before and can be arranged after each subsequent stage 2. The size of the waste chutes, especially their width in the direction of the press run measured, is dependent on waste. The invention aims at the elimination the clipboards in the so-called empty space areas and on a reduction in the width of the stand areas 6.
  • FIG. 2 shows a multi-column press as a subsequent stage press, the upstream drawing press with drawing stage 1 also can be omitted.
  • This multi-column press with e.g. three press stands - Stand areas 6 - is on the foundation side across the width of the multi-column press extending cross member 4 set up.
  • Press tables positioned, which are firmly placed on the crossbars 4 are that can be made in one piece and the sliding tables wear with tools 8.
  • the upper parts of the tool are in operation one-piece press ram 7 attached.
  • the press stands 6 are in front of and behind the press ram 7 connected by side members 5.
  • gearboxes 11 are placed.
  • the gear boxes 11 serve to accommodate motion deflection devices, possibly also e.g. hydraulic Driving means for the up and down movement of the Press ram 7.
  • the means are driven in the drive boxes 11 via motors 11, a flywheel 19 and a driven shaft 20 outside the gear box 11, as shown in Fig. 4.
  • Of the Press ram 7 is here in three levels according to the number of stand areas 6 via led out downwards from the drive boxes 11 Conrod 17 driven.
  • a transfer device is through the press system 9 for the transport of the sheet metal parts in the stages in the press pass extending through.
  • 3, 4, 5, 7 and 9 is the double arrangement of tie rods 13 in the central stand area 6.
  • the tie rods 13 Overall, tie rod sleeves 14 for support, dimensional accuracy and bypass force.
  • 5 is the press ram 7 in longitudinal or linear bearings 23 can be raised and lowered.
  • Fig. 6 shows one of several drive boxes 11, here in the drive box 11 arranged in the middle region of the press ram 7.
  • the drive box 11 is above the press stand 6 on the longitudinal beams 5 extending in front of and behind the press ram 7 attached and fastened via four tie rods 22 with tie rod sleeves.
  • the figures 7 and 8 move from the main shaft 20 (Fig. 4) Drive means, including a connecting rod 17 with the force transmission 18 recognize in the press ram 7.
  • the centers of the tie rods 13 one Stand pair 12 and the center of the force transmission 18 - connecting rod 17 - in the press rams 7 lie on a common line 16.
  • For the mean force 18 are both of the tie rods required here 13 on this common line 16.
