Definitions

  • the invention relates to a press line or Large step press with a transport device for Transporting workpieces according to the generic term of Claim 1.
  • This transport step can be from a press in the subsequent press, or at a large-scale press, from a forming station in the next.
  • the workpieces or tools are not so simply designed for transport in 2-axis operation enable. Examples of this are in the car doors in the first forming stage pulled from a common board around in the course of a cutting process each as Separate workpieces together to the processing stages run through. To avoid consuming and complicated Tools must be in the workpiece during the transfer process an optimal processing position can be brought. These Change of position is usually through clipboards or Orientierstationen carried out.
  • Such a clipboard for both individual and Double parts, shows the EP 0 383 168 B1 or DE 196 51 934 A1. Particularly noteworthy are the five degrees of freedom to change the position of elaborately designed workpieces can be used. The workpiece position can thus at Need to be manipulated in up to five axes.
  • the invention is based on the idea, one for each Tool stage own driven transfer so to make that for each workpiece adapted to the forming process optimal change in position is feasible.
  • the functionality is intended for both individual users large-scale workpieces as well as for 2 workpieces, as so-called Double parts, to ensure.
  • the crossbeam is the Traverse sucker. This function is achieved by the cultivation of tool-specific transport and holding means to the Crossbeam.
  • a movement overlay Transport curve or a transport step consisting of Vertical and horizontal movement executed.
  • the Transport step is used to implement the workpiece of for example, forming stage 8 after forming stage 9.
  • the cross-beam 5 is around the Pivoting axis 12 pivotable.
  • a drive 10 causes via a Toothed belt drive 11 the pivoting of the cross-beam 5.
  • FIG. 1 Illustrative form are different layers of Crossbar 5 in Figure 1 recognizable.
  • FIG 2a + b shows cross-beam 5 in Horizontal position and vertical inclination. recognizable is the opposite arrangement of Transport devices 2.1 and 2.2 with mounting on the left and right stands 3.1 and 3.2. Exemplary are in FIG 2a + b arranged on the cross-beam 5 movable workpiece-specific Saugertraversen 13 for transport provided by double parts. Without any restriction is also the use of only one centrally located Saugertraverse 13 possible, as it is e.g. to transport a large, not yet split board or a large one Workpiece is required. A Transverse displacement can be provided as movement.
  • the vertical inclination of the cross-beam 5 is through different movements of transport device 2.1 and 2.2 achieved.
  • required length compensation is a Splined shaft 14 is provided.
  • the universal joint 15 allows the angular position of the cross-beam 5. Instead of one Cardan 15 is initially for this skew a rotation axis sufficient.
  • Figure 3a + b shows the end of the swing arm 4 of Transport device 2 with the receptacle for the cross-beam 5.
  • the toothed belt drive 11th integrated, for pivoting the cross-beam 5 to the Rotary axis 12.
  • the splined shaft 14 transmits on the one hand the Rotary movement and also allows the length compensation at inclination of the crossbeam 5.
  • Attached is the Splined shaft 14 with universal joint 15.
  • the swiveling Bearing 17 carries drives 18, 19 which over waves and Angular gear drive Spindle nut system 20 and 21.
  • In operative connection with spindle nut system 20 are Double-sided rods 23 in conjunction with Circle segment 24 and this pivot in the fulcrum 25.
  • the size of the swivel angle is W1 and W2.
  • the Guidance and support of the circular segment 24 takes place Segment guides or guide rollers 26 instead of the Horizontal slide 27 are attached. With the circle segment 24 is the suction traverse 13 holding the workpiece connected. Guides 28 serve to guide the Horizontal slide 27. This horizontal slide 27 is to the dimension M1 and M2, relative to its central location, traversable. Horizontal carriage 27 is driven over Rod 29 and spindle nut system 21 by drive 19.
  • This described device can be both in a simple form as be mounted twice on the crossbeam 5.
  • a Motion overlay is due to simultaneous actuation of the Drives 18, 19 possible.
  • the speed control can be too same or different speeds lead, which optimal handling conditions of the workpieces are achieved.
  • the cross-beam 5 can be uncoupled as this e.g. when converting from a double part to a large-scale item may be required.
  • the drives 18, 19 are not replaced and remain in the press 1.
  • a combination of pivoting and horizontal movement of the Saugertraverse 13 is not mandatory in every case required.
  • the cultivation can be designed that only one movement at a time is possible, d. H. of the Carriage 27 can then be omitted.
  • FIG. 4a + b shows a plan view of the crossbeam 5 in FIG horizontal position and horizontal inclination in Part transport direction according to arrow 30.
  • the Double-sided arrangement of the actuating rods 23, 29 and in the extension of the pan and Querverfahr is presented, layed out.
  • the Saugertraversen 13 respectively grown in duplicate.
  • the invention is not limited to that described and illustrated Embodiment limited. It also includes all professional designs within the framework of the applicable Claim 1.So is a universal joint as a movable storage only to be understood as an example and all can be spherical Joints the prerequisite of the inventive idea be used.
