Definitions

  • the invention relates to a transfer press line for processing large-area sheet metal parts in several work stages according to the preamble of claim 1.
  • a known press system of this type (DE-OS 39 05 069) consists of several presses set up at a short distance from one another, the press tables and head pieces of which are connected to one another by separate press stands or by two presses associated with two adjacent presses and which are connected by means of connecting shafts from a central drive are driven synchronously.
  • Each press contains only one stage. In the stand area between two work stages, an empty stage is provided in which the sheet metal parts are stored in a position-oriented manner. When changing tools, the height of the clipboards and the size, shape and inclined position of the sheet metal parts can be adjusted fully automatically using adjusting devices.
  • suction traverses which are slidably mounted in mounting rails that extend through the entire press system and are driven by the press drive via a cam mechanism.
  • suction traverses - detached from the mounting rails - are placed in the slots of the sliding tables and extended together with the tools from the press.
  • the clipboards in the empty stages are provided with part-specific storage stations which, when the tool is changed, are inserted in the receptacles provided on the sliding table in addition to the suction traverse and are moved out of the press together with the tool set.
  • the storage templates and suction traverses assigned to the new tool set are returned to the press in reverse order.
  • a disadvantage of the former solution is the considerable control effort for the automatic adjustment of the clipboard to the respective part shape and in the latter solution the high effort required for the automatic coupling and locking systems both on the clipboards and on the sliding tables.
  • the storage templates and suction traverses which are locked to the side of the tool set on the sliding table, require a not inconsiderable amount of space, which leads to a larger press stand width in the direction of travel of the sheet metal parts.
  • This increases the mass used, in particular for the rams guided on the press stands with optimum rigidity requirements and a favorable guidance ratio, which in turn has a negative effect on the dynamics of the drive.
  • the limited space between press stands and sliding tables considerably limits the use of wide suction spiders, which limits optimal handling of the sheet metal parts.
  • the invention is based on the problem of designing a transfer press line according to the preamble of patent claim 1 such that, due to a narrower design of the sliding tables in the parts transport direction, due to the elimination of the superstructures required for the coupling systems for receiving the suction crossbeams or suction spiders and If necessary, the storage templates in addition to the tools when changing the tool shortens the column width of the individual presses and thus improves the rigidity and dynamic behavior, while at the same time making the systems for changing the suction traverses and storage templates easier and clearer.
  • the press tables 2 - seen in plan view - are preferably of I-shape (FIG. 3) and are mounted on the foundation 8 by means of columns 7 (FIG. 1), the press tables 2 of the adjacent seizures 1.1 - 1.3 each being on common columns 7 stored and possibly connected in their outer area by means of clamping bolts 9. In this area, the elastic deformation of the press tables 2 goes to zero.
  • the width of the press stand 4 and its position on the feed tables 2 is selected so that there is a free space between the press stands 4 of adjacent feeds 1.1 - 1.3.
  • Only one working level is assigned to each press 1.1 - 1.3.
  • An empty level is provided between each work level, in which the sheet metal parts are placed on intermediate shelves in a position-oriented manner and their position may be changed.
  • the tools 10 are arranged on sliding tables 11 which can be moved out of the tool space of the presses 1.1-1.3 when the tool is changed.
  • two support rails 12 are provided which run through all the presses 1.1 - 1.3 of the line and are connected to one another by suction crossbeams 13 or crossbeams equipped with suction spiders and their movement via Drawing is not derived from the press drive with cam gear or cam coupling gear shown.
  • suction crossbeams 13 or crossbeams equipped with suction spiders and their movement via Drawing is not derived from the press drive with cam gear or cam coupling gear shown.
  • the transport would of course also be possible in a known manner by means of gripper rails that can be moved in two or three dimensions.
  • each empty stage there is a storage and retrofitting station 14 in which the template supports 15 for receiving the part-specific, interchangeable storage templates 16 can be adjusted in height by means of a lifting device 24, can be pivoted by a limited angle by means of a swivel drive 25, and can be displaced in the transport direction by means of an actuator 20 (Figs. 4 and 5).
  • the template carriers 15 are designed to be divided and can be lowered into a vertical position by swivel drives 17 when changing tools for space reasons.
  • Above the template carrier 15 there are two receptacles 18, 19 for the suction traverse 13 or suction spinning when changing the tool.
  • the receptacles 18, 19 are provided with lifting devices 26 and with locking means by means of which the suction cross members 13 or suction spiders are successively decoupled from the support rails 12 and placed one above the other on two levels.
  • the receptacles 18, 19 can be pivoted into a horizontal position by means of swivel drives 23.
  • swivel drives 23 In the same way, it would of course also be possible to design only one receptacle 18 with corresponding detents in such a way that the two suction cross members 13 can be accommodated one above the other.
  • suction traverses 13 that are wide in the direction of transport, it may be necessary for reasons of space. also expedient to pivot them in the receptacles 19 into a vertical position.
  • the storage and changeover stations 14 with the storage templates 16 and suction traverses 13 or suction spiders located thereon are moved through the space between the press stands 4 of the adjacent presses 1.1 - 1.3 by means of separate drives on rails 22 analogously to the Sliding tables 11 extended out of the empty step areas and replaced by the ready ones, already converted to the next sheet metal part to be machined outside the presses.
  • spacers 21 (FIG. 1) between the head pieces 3 and the upper area of the press stands 4 of adjacent presses 1.1 - 1.3 (FIG. 1), which - to compensate for the expansion of the press frames under load - are elastic in the vertical direction, but stiff in the horizontal direction are executed.
  • the spacers 21 could consist of two flanges which can be screwed onto the head pieces 3 and by means of a resilient intermediate web, e.g. B. a relatively thin sheet, are interconnected (Fig. 5).
