Definitions
- the invention relates to a transfer press or the like. Forming machine with the means specified in the preamble of the claim.
- the forming machines are multi-stage presses, body presses, press lines, multi-stage presses, transfer presses, on which sheet metal parts, even large dimensions, e.g. Body parts are molded. Depending on the size of the sheet metal parts to be formed, the distance between the processing stages and thus the transport path are large.
- DE 39 31 081 A1 describes a clipboard on which sheet metal parts are temporarily stored.
- this has templates which can be adjusted to a higher level and in their inclined position and in further movements.
- One of these movements is a correction movement for error compensation after swiveling the sheet.
- the mounting plate supporting the structure of the clipboard is mounted horizontally in the direction of the transfer movement in rails and can be displaced by means of an adjusting means, motor and spindle.
- the advantages of the invention can be seen in the more favorable design of the transfer device using the possibilities of the clipboard, without the clipboard being more expensive or more complicated to implement. It is essential for the invention to be detached from the previous consideration that the transfer means must bring about the overall movement of the sheet metal parts.
- tools of which the tool lower parts 1 and 2 are indicated, are inserted in a forming machine via sliding tables 3 and 4 which can be moved out of and into the forming machine.
- an intermediate storage space 12 is indicated, which, in the manner described for DE 39 31 081 A1, to compensate for the error in the rotation of the stencils 18, into the position 18 1 with the sheet metal part 7 resting thereon, 7 1 in positions 12 1 can be moved.
- a sheet metal part 6 which can be implemented in the transfer movement 13 by means of the drive and suction bar 9 known from DE 39 05 068 A1 and can be stored in the position 12 on the clipboard 12.
- the sheet metal part 7 1 rotated on the stencils 18 into position 18 ′ and newly aligned to the lower tool part 2 by moving the clipboard into position 12 1 is moved into the support on the lower tool part 2 by means of suction bars 11.
- the conversion movement 13 or 14 of the suction bars 9, 11 can, as in FIGS. 1, 2, 3 shown, takes place in the same movement, the return movement 15 or 16 can take place differently due to the drive, with a movement delay in the area of the supports 5 on the sliding tables 3, 4 during the tappet descent. 1 assumes a conversion movement for the sheet metal parts 6, 7, which is carried out overall by the suction bars 9, 11, the FIGS. 2 and 3 diagrammatically the repositioning movement and return movement sequences which omit a partial route 17.
- the transfer movement 13 in FIG. 2 begins with the removal of the sheet metal part from the lower tool part and ends well before the position, half the distance between or in the middle of the machining stages, represented by the centers of the lower tool parts 1, 2.
- Fig. 3 is based on a larger transfer movement 13 for, for example, a larger sheet metal part.
- the tool lower parts are therefore at a greater distance from one another than drawn in FIG. 1.
- the lower part 1 of the sheet metal part 6 removed and converted into the region of the intermediate storage 12 already before the half distance resulting from the centers of the lower part of the tool. 2 and 3 can be seen equally the removal of the sheet metal part 7 1 far behind half the tool distance, seen in the direction of the transfer movements.
- the clipboard 12 is now used to bridge the partial path 17 which is not traversed by the transfer device with the suction bars 9, 11. This makes it possible, in the return phase of the suction bars 9, 11, return movement 15, 16, to bring about a conversion movement of the sheet metal part 7 1 resting on the clipboard 12. Likewise, the return of the clipboard 12 into the takeover position, left end region of the partial route 17, into the transfer movement 13, 14 of the suction bars 9, 11 already beginning is possible.
- Fig. 4 shows the means already known from FIGS. 1 to 3 with the partial path 17.
- the correction path of the clipboard 12, which does not represent a partial path, is positioned at 10 and is anyway due to the change in the inclined position of the sheet metal part 7 on the templates according to DE 39 31 081 A1.
- the sheet metal part 6 removed from the lower tool part 1 by means of the suction bar 9 is brought into the position shown on the right in accordance with the curve profile 13.
- the conclusion is a lowering movement for supporting the sheet metal part 6 on the stencils 18.
- the sheet metal part 7 has been removed from the stencils 18 of the clipboard 12 and placed in the lower tool part 2.
- the removal position for the sheet metal part 7 is offset by the partial path 17 and the correction path 10 to the right in the transfer direction with respect to the storage position of the clipboard 12.
- the squeegee 9 on the stencils 18 of the clipboard 12 which is moved to the left counter to the transfer movement, is also rotated into a new inclined position, if this movement should be necessary, via the partial path 17 and the correction movement is carried out. These movements can run in parallel.
- the suction bar 11 is thus to be brought into the position for removing the sheet metal part, here 6, which is characterized by the position 12 1 of the clipboard.
- FIG. 5 first shows a clipboard 12, as known from DE 39 31 08 A1, which has been changed by the measures required to solve the task. Based on the known design, the changes are added.
- the mounting plate 26 can be displaced on the rails 21 in the direction of the transfer movements 13, 14 by means of guides 27.
- the rails 21 are extended on both sides by the rail parts 22.
- the frame 19 is extended in the same way to the size that is positioned at 20.
- the motor 23 had to be moved and the spindle 24 had to be extended to the total length 25.
