Definitions

  • the invention relates to a device for the three-dimensional drive of gripper rails according to the preamble of claim 1.
  • Devices of this type in a multi-column press are used for moving the sheet metal parts, inserting them into tools, removing them from them and transporting them to the following processing or removal stage.
  • the movement drives of the gripper rails in the three axes should not be tapped from curves.
  • either individual cams were required or maximum paths were assumed that can be achieved with a single set of cams.
  • DE-C2-33 29 900 describes a device for three-dimensional transfer in which the movements of gripper rails in the three axes are brought about by servo motors.
  • the motors are not in the immediate effective area of the gripper rails.
  • Gear chains and linkages are required, which lead to inaccuracies in the axes at the required high accelerations with repositioning movements of, for example, 16 parts and more per minute.
  • the rotary movement of the servo motor for the clamping / releasing movement is transmitted via a pinion-rack connection to slides that can move horizontally and transversely to the transfer movement.
  • the same means as described above are also shown in DE-A1-32 38 729.
  • the servo motors for two movements of the three-dimensional movement drive of the gripper rails are arranged in the center, but below the gripper rails in a lower part of the lock case.
  • Claim 2 characterizes an advantageous embodiment according to the invention.
  • the arrangement of the motor at the height of the gripper rails and slide is particularly advantageous, since this enables a direct drive for the clamping / releasing movement to be implemented.
  • a servo motor with a drive shaft on both sides was integrated into the console-like structure.
  • the resulting symmetrical design increases torsional rigidity.
  • the lock box thus forms a functional, complete unit.
  • Rails 12 for carriages 11 which can be moved transversely to the transfer direction 27 are fastened on the carrier plates 13.
  • the lifting and lowering movement of the motor 17 is thus transmitted to the gripper rails.
  • the slides 11 carry spacer bolts 9, which are guided upwards through cross slides 7 and carry guides 4 for the gripper rails 3 guided in them at the upper ends.
  • the carrier plates 13 are supported by balancing cylinders 20.
  • the console plates 16 carry a frame 6 in the upper region.
  • the frame 6 is provided with guides 8 in which the cross slides 7 can be displaced in the tensioning and releasing direction 29.
  • the displacement movements of the cross slides 7 are brought about by a servo motor 18 mounted in this structure at the level of the cross slides 7, the shaft of which is guided out of it on both sides.
  • the shaft parts are provided as spindles 23 with a right-hand thread or with a left-hand thread.
  • the threads interact with lock nuts 24, 26, cage nuts or the like. Spindle nuts in or on the cross slide 7.
  • the movement drive of the gripper rails 3 takes place in the conversion direction 27 z. B. in the manner mentioned from the prior art.
  • the lifting and lowering movement of the gripper rails 3 takes place starting from the motor 17, motor shaft 19 and spur gear. Pinion, rack and pinion drive 21, 22, 14 and slide 11 by means of spacers 9 on the guides 4, for which purpose the guides 12 for the slide 11 must extend over the tension-release movement path of the gripper rails 3.
  • the guides 8 are also to be designed in the same way.
