Definitions

  • the invention relates to a multi-station press with the features of claim 1, in particular a multi-station press for the production of larger ones Body parts.
  • Such multi-station presses have press stations in which forming tools (consisting of upper tool and lower tool) are arranged. Operational the sheet metal parts from press station to press station passed on to gradually transform them. While the first press station usually has a drawing stage is in which a relatively strong workpiece deformation takes place, the shape changes of the workpiece are in the subsequent press stations are usually much lower. The behavior required accordingly Powers.
  • Multi-station presses with separate, together reach linked press stations when they are to be processed larger sheet metal parts are set up, very much large dimensions, which makes them correspondingly expensive.
  • One goal here is that required for the press To keep installation space and costs as low as possible.
  • DE 33 22 377 A1 describes a multi-station press known, the press frame several, on one in Press table set up in the longitudinal direction, has so-called stand tops, two of which are platforms extending in the longitudinal direction are carried.
  • the Platforms form side members, between which two head pieces to drive the plunger located below are held.
  • the multi-station press according to the invention has state of the art under which there are several press stations extending plunger as load-bearing elements two at a distance longitudinal beams arranged parallel to each other. These can be used separately in each press station Tables are stored, which are then only the press width, but not the total length of the pestle overstressed press stations.
  • the Press tables are therefore smaller and easier to handle and they have to be less rigid on their own be interpreted.
  • the required bending stiffness yielding longitudinal beams are stationary and arranged laterally, so that as an additional advantage under the press tables, for example in the middle of the press, in the direction of travel there is free passage.
  • the Workstations operated, both in the area of the stand portals can also be arranged between them.
  • This construction is in the area of the head pieces neither a continuous side member nor an over the Length of the tappet continuous head piece required. This also reduces the effort compared to press frames continuous side members in the head area considerably without that there are losses in stability. this applies especially for presses that are used to machine larger Sheet metal parts are set up.
  • Compared to presses with not integrated or separate press stations not only does the construction cost decrease, but also the overall size, because it is possible the individual press stages, operated by the common plunger, very much to move close together. This reduces the required Press length. The effort is reduced accordingly.
  • the proposed solution is through the summary several press or forming stations unsupported span neither of the head pieces nor the Tables increased.
  • the span stressed on bending the table construction is compared to known solutions also greatly reduced.
  • each Headpiece has two eccentrics driven in opposite directions, which are connected to the tappet by connecting rods. Force symmetry can thus be achieved.
  • the ram can move over two press stations extend away. However, it is advantageous if this at least three or more press stations together operated. The number of headers, guides, etc. does not increase further, so that the proportionate Cost per press station decrease.
  • the stand portals are separate from each other what can in particular include that the headers of the Stand portals not with each other or in the direction of flow are connected to each other only under tension and pressure. Corresponding rods or struts can be between the Head pieces can be mounted.
  • the headers that are on the press stands standing on the basic supports Tension anchors against the press stands and the basic carriers curious; excited. The press stands then transfer into each Phase of operation of the multi-station press only pressure forces.
  • the plunger is three or more than three Press stations spanned and the two column portals are arranged at a distance from one another, it is advantageous if the longitudinal basic beams serve as bending beams are trained, the forces of between the Stator portals arranged on the press stations transfer to neighboring press stations. This results in a particularly simple structure of the frame or scaffold the multi-station press.
  • FIG. 1 shows a multi-station press 1
  • a drawing stage 2 and 3 with respect to a direction of passage T has subordinate forming stages 3, 4, 5. While drawing stage 2 has its own tappet 7 has, the forming stages 3, 4, 5 have a common Ram 8.
  • the drawing stage 2 has a means suitable carrier or feet 11, 12 stationary Table 13 on which a sliding table below the ram 7 14 is stored.
  • a total of four on table 13 standing press stands 15a, 15b, 16a, 16b (Fig. 3) carry a head piece 17. This rests on the press stands 15a, 15b, 16a, 16b and contains only one schematically indicated main drive 18, which, as from 1 and 2 can be seen, the tappet 7 via connecting rods 19th drives. These engage on the tappet 7 from FIG. 4 apparent pressure points 21.
  • the downstream forming stages 3, 4, 5 form one structural unit, made up of two longitudinal basic girders 22, 23 is worn, which in turn on plinths 24 store.
  • On the base beams 22, 23 are transversely extending Tables 25, 26, 27 placed and fastened on the in turn each carry a sliding table 31, 32, 33.
  • the sliding tables 31, 32, 33 are below the ram 8 arranged and serve to accommodate corresponding lower tools, with the associated upper tools the plunger 8 are to be attached.
  • Stand portal 36 include press stands 38a, 38b, 39a, 39b.
  • the press stands 39a, 39b can with the Press stands 16a, 16b each to form a structural unit be united.
  • the total of four press stands 38a, 38b, 39a, 39b carry a head piece 41, which two of contains the main drive 18 ago driven eccentric. These are connected to the tappet 8 via two connecting rods 43, the pressure points visible on the plunger 8 from FIG. 4 Define 43.
  • the press stands 38a, 38b, 39a, 39b are arranged so that the head 41 above the Forming stage 3 is arranged, the head piece 41st does not protrude into the area of the adjacent forming step 4.
  • the second stand portal 37 is at the forming stage 5 arranged and contains four press stands 44a, 44b, 45a, 45b.
  • the press stands 44a, 44b, 45a, 45b are on stored the table 27 and contribute to the stand portal 37 belonging head piece 47, which above the table 27 is arranged and not in the area of the forming station 4 protrudes.
  • On the head piece 47 are two opposite, from the main drive 18 driven eccentric arranged are connected to the plunger 8 via connecting rods 48.
  • the Connecting rods 48 run synchronously with connecting rods 42 and define pressure points on the plunger 8 from FIG. 4 48.
  • the head pieces 41, 47 are against anchors 49 against the base support 22, 23 stretched, the in the Figures only dash-dotted indicated anchor 49 through the press stands 38, 39, 44, 45 and through the Tables 25, 26, 27 extend.
  • the tension anchors 49 serve in particular the inclusion of the head piece 41, 47 attacking reaction force when driving the plunger 8 arises and temporarily after a press circulation is directed above. From the forming stations 3 and 5 these forces are on the table side in the base support 22, 23 initiated and directly on the tie rods 49 on the Transfer headers 41, 47. The situation is different at the forming station 4, which is between the stand portals 36, 37 is arranged. By the pressing force the plunger 8 claimed here to bend, whereby he be reinforced in the area of the forming station 4 can.
  • one or two struts 51, 52 may be provided which in essentially only claimed on train and / or pressure become. These struts 51, 52 relieve the base support 22, 23 with regard to their bending stress. However the struts 51, 52 themselves are not subject to any bending stress. You can screwed to the head pieces 41, 47 or otherwise connected.
  • the basic structure of the press frame of the forming stages 3, 4, 5 is defined in that along two running basic beams two at a distance from each other arranged stand portals 36, 37 are arranged, the bridge the base beams 22, 23 in the transverse direction.
  • Tables 31, 33 are below the column portals 36, 37 arranged, which also bridge the base beams 22, 23. If necessary, can between two stand portals 36, 37 another table 26 may be arranged, the also bridges the base beams 22, 23 in the transverse direction. Irrespective of this, the head pieces 41, 47 lead the Stand portals 36, 37 together a single plunger 8, which is assigned to all the forming stations 3, 4, 5.
  • the multi-station press 1 described so far works as follows:
  • the forming stages 3, 4 following the drawing stage 2, 5 each require lower actuation forces than that Drawing stage 2. This ensures that the load on the Conrods 42, 48 and those driving them accordingly Eccentric devices overall in the same order of magnitude lies like the load on the drive device draw stage 2.
  • the pressure points 43, 48 are arranged on the plunger 8 in such a way that its bending load is minimal. This is achieved by the pressure points 43, 48 not exactly at the ends of the plunger 8 or in the middle of the forming stages 3, 5 are arranged, but something in the direction moved to the intermediate forming stage 4.
  • a large part transfer press is used to minimize costs 1 several forming stations 3, 4, 5 under a common plunger 8 arranged.
  • the table construction consists of two longitudinal or basic beams 22, 23, one table 25 per forming station 3, 4, 5, 26, 27 placed transversely and fastened if necessary.
  • the plunger 8 is driven by two independent headers 41, 47, depending on the number of Stations arranged with or without spacing next to each other are and span only one forming station 3, 5.
