Definitions

  • the invention relates to a tool changing device and especially the squeegee changing device in Press lines, large section presses or the like the preamble of claim 1.
  • press line or large section press Transfer devices for parts transport are provided.
  • the Transport process by separate, each press or Transport systems assigned to the press stage.
  • This individually Controllable or regulable devices serve to discharge the workpiece to be formed from a tool level and Feeding into the subsequent tool stage.
  • the invention has for its object the above to avoid disadvantages described in the prior art and a tool changing device and in particular one Change device for the parts-specific accessories shape that accessibility through the press room this is not hindered.
  • the exchange device should be inexpensive and as a kind of modular system be space-saving.
  • the task at hand can be achieved by the inventive solution both by using individual features, as well as in inventive combination the disadvantages of the prior art Avoid technology.
  • the idea of the invention lies here based on the changing device for the parts-specific Arrange accessories in this way and the movement sequence design that this hinders the accessibility of the Press room is avoided.
  • the changing device is equipped with a mounting and if necessary with a clamping system for the suction beam.
  • the Suction block can be rotated about its axis. This Rotating device can either be part of the Change device as an alternative to the transport system his.
  • the transport system When changing tools, the transport system is located with the Vacuum bar in the stand area in a parking position. The The upper tool is opened by a downward movement of the ram the lower tool moved and the tool clamps loosened.
  • the transport system When the changing device is driven by means of a linear drive is the movement of the transport system as in 2. described. To reduce the required extension path The transport system also moves the change device in a lower position that is slightly larger than half Width of the suction spider is. The transfer of the sucker bar to depending on the design and location of the Recording by a vertical as well as a horizontal movement respectively.
  • the invention is particularly expediently designed such that the tool changing device is a kind of modular system represents.
  • the proposed solutions will cost-effective and very compact design achieved.
  • the drive for the swivel movement as well as the linear drive is fixed to the sliding table, which is next to one Reduction of the masses to be accelerated also for the Connection of the electrical lines is advantageous.
  • the section of a large section press 1 is shown in FIG seen.
  • the forming stages are labeled 2.1 to 2.3, 2.1 and 2.3 are only shown in half a view are.
  • From the press 1 are the rams in a simplified form 3.1 to 3.3 and the stands 4.1 and 4.2 can be seen.
  • the Press 1 retracted the sliding tables 5.1 - 5.3 which the Wear lower tools 6.1 to 6.3.
  • the upper tools 7.1 to 7.3 are attached to the plungers 3.1 to 3.3 by means of grips attached.
  • the transport system 9.1 9.2 Workpieces not shown in the transport direction 8 transported through the press 1.
  • FIG 2 the situation of the transfer of the suction bar 10th from the transport system 9 to the changing device 12 shown.
  • the swivel arm of the transport system 9 is located itself in a vertical position and the inclusion of the Change device 12 is on the same vertical axis 16 pivoted.
  • the transport system is by means of a drive 17 9 vertically movable and thereby the suction bar 10 in a recording formed as a clevis 18 Exchange device 12 are passed.
  • On the clevis 18 is also a clamping device for a secure hold of the Sucker bar 10 attached.
  • the suction spider 11 is located in a horizontal position.
  • the Change device 12 is carried out twice and each in End region of the sliding table 5 attached and stored.
  • the Clevises 18 for receiving the suction beam 10 are on one End connected to the swing arm 20. Is about the axis of rotation 13 the pivot arm 20 is rotatably supported at its other end.
  • the drive 21 causes the pivoting movement Pivoting movement of the fork head 18 through the belt drive 19 is integrated in swivel arm 20.
  • FIG Swiveling of the fork head 18 is dispensed with and the Belt drive 19 of the changing device 12 is omitted. That turning of the suction beam 10 in a vertical position of the suction spiders 11 carries out the transport system 9. For this purpose swings the transport system 9 in the change position and rotates the suction bar 10 such that the suction spider 11 is vertical is arranged. By a vertical lowering movement of the Transport system 9, the suction beam 10 in the fork head 18 laid. After the fully automatic uncoupling of the Sucker bar 10 from the transport device can do that Transport system swivel into a position that is trouble-free The sliding table can be extended. In the proposed solution can possibly be on the clamping in Fork head 18 for the suction beam 10 can be dispensed with, thereby once again simplifying the changing device 12 is achieved.
  • the dash-dotted representation of the location of the Change device 12 corresponds to the situation during the Change of the suction bar 10 or generally in the tool and Accessory changes.
  • the parking position shown can also be used without restriction for both embodiments rotated by 180 °, directly on the Front of the sliding table.
  • the changing device 12 can be equipped with another axis of motion.
  • the Swivel arm 20 would be movable as a telescopic arm, such as by arrow 23 indicated in Figure 5, executed.
  • the movement can by means of a spindle drive or cylinder. Is the Wide sliding table and thus the extension of the Vacuum spider can be problematic due to the cramped space these are placed on the tool 6, 7.
  • the swivel arm 20 would extend as a kind of telescope on one for this purpose Position above that placed on the lower tool 6 Upper tool 7.
  • the swiveling receptacle 18, according to FIG. 1 to 3, can then with the suction spider 11 via the tool 6, 7 swivel in.
  • the swivel arm 20 can optionally still to be swiveled further towards the tool in addition to the To optimize the exit situation.
  • FIG. 6 An exemplary embodiment using a linear drive is shown in Figures 6 and 7 shown. Located during production the changing device 12 below the cover 14 in lowered position and the space 15 is free walkable.
  • Figure 7 shows the change position. Is clearly recognizable that due to the retracted low position of the Transport system 9 the extension path of the changing device 12 can be small. This stroke is by means of a Telescopic cylinder 22 driven. As a drive for the Other telescopic systems, such as B. serve a kind of scissor table.
