Definitions

  • the invention relates to a device for converting sheet metal parts in a press system with the further means according to the preamble of claim 1.
  • press systems the conversion speeds of the sheet metal parts from the insertion or orientation stage through the are increasing due to ever increasing sheet metal parts to be processed or larger batch sizes Press system getting bigger and bigger until the workpiece is released. In the past, this has led to low-mass transfer devices.
  • a center error of the sheet metal part arises as a necessity for removal from the tool and / or with reference to the position of the sheet metal part in the subsequent tool.
  • a device for converting sheet metal parts in a press system in which the sheet metal parts during the movement from the processing stage to an intermediate storage and further into the subsequent processing stage with regard to the position of the sheet metal parts in the Tools are rotated.
  • the device has suction cross members.
  • the crossbeams are fixed at the end in pivot bearings on rail-guided carriages.
  • the carriages are press-controlled in travel movements via a transport linkage; the rails can be raised and lowered accordingly.
  • DE-A-39 31 081 describes a clipboard in a storage station mixing two processing stages of a press.
  • the clipboard has templates for supporting the sheet metal parts, which can be adjusted in height, distance and inclined position for another sheet metal part or for a subsequent processing step by means of adjusting and moving deflection means.
  • the error caused by swiveling the sheet metal part must be corrected with the adjustment means for the horizontal and vertical movement of the templates.
  • a device for converting sheet metal parts in a press system in which sheet metal parts holding and moving these holding means are designed as cross members and are attached at the end to carriages.
  • the cross beams can be moved horizontally by drives on rails and can be raised and lowered with them.
  • the point of attachment of the crossbeams to the carriage can also be adjusted in the direction of the movement of the carriage by another drive. With the device shown here, sheet metal parts are not moved in an additional displacement movement relative to the carriage during the transfer movement.
  • Claim 2 represents an advantageous embodiment of the invention.
  • Another important advantage of the invention is that corrective movements, e.g. those that are required by turning the crossbar can be compensated.
  • a running rail 1 is shown, or the like in a press, transfer press. Press system in the direction of the double arrow 21 can be raised and lowered.
  • the running rail 1 extends in the direction of the transfer movement 20 of sheet metal parts 11 through the press.
  • the running rail 1 is provided with running surfaces 2, on which running rollers 6 of a carriage positioned in total with 3 roll.
  • the carriage 3 shown is divided into two parts in its basic structure with a carriage part 4 and a carriage part 5.
  • the carriage part 5 has a fulcrum 12, which serves as an attachment point for a cross-member 10 rotatably mounted here. This is with suction cups or the like.
  • Means 13 are provided for holding sheet metal parts 11 when removing them from the unstacking station or the tool and for transferring them to the following station until they are placed in the latter.
  • Between the carriage part 4 and the carriage part 5 is a linear motor, pressure cylinder or the like.
  • Adjustment means 9 attached for a relative movement between the carriage parts 4 and 5.
  • the carriage part 5 is connected to the carriage part 4 and moves like this as a result of the press drive.
  • an additional movement over the length of the adjustability of the adjusting means 9 is possible.
  • the spindle 23 or the piston of the adjusting means 9 is in the at least partially extended position during the moving movement of the carriage 3, it is possible to reduce the total movement of the carriage 3 or the carriage part 4 when the adjusting means 9 is acted upon.
  • the crossbar 10 is rotated here by means of a rotary motor 14 which is flanged to the carriage part 5 is.
  • Crossbar 10, rotary motor 14 and thus the attachment point 12 are guided in rails 24 and can be raised and lowered by means of adjusting means 25.
  • Fig. 2 shows in addition to the multi-part of the carriage 3, the action of the carriage part 4 by the transport linkage 7 and the arrangement of the rotary motor 14.
  • the crossbar 10 is shown broken off.
  • the other end part of this is rotatably mounted on a carriage, which is equally designed and movable in a second rail.
  • 3 shows the individual parts of the carriage, here the carriage part 5.
  • Fig. 4 shows the same carriage structure as previously described.
  • the rotary movement of the crossbar fixed in the pivot point 12 takes place from a cam follower lever 17 placed against a cam 15 which can be displaced by means of a linear adjusting means 16 and an angle lever 18 with a pivot point at the attachment point 12.
  • the cam follower lever 17 is held against the cam 15 by means of an air cylinder 19; the curve 15 can be adjusted by the adjusting means 16 in the longitudinal guide for an instantaneous rotation of the cross-beam.
