Definitions

  • the invention relates a multi-column press with a device for three-dimensional drive of gripper rails according to the preamble of claim 1.
  • Devices of this type in a multi-column press serve the transfer movement sheet metal parts, insertion into tools, removal from them and transport in the following processing or removal stage.
  • the movement drives of the gripper rails in the three axes (three-dimensional) cannot be tapped from curves.
  • To open the press when changing the workpiece or tool To be able to set the new conditions, either individual cams were required, or maximum paths were assumed that can be achieved by a single cam set become.
  • DE-C2-33 29 900 a multi-column press with a device for three-dimensional transfer according to the preamble of claim 1 described in which the movements of gripper rails in the three axes by servo motors is effected.
  • the motors are not in the immediate effective range of the Gripper rails.
  • Gear chains and linkages are required, which are required for the high accelerations during repositioning movements e.g. 16 parts and more per minute lead to inaccuracies in the axes.
  • the rotation of the servo motor for the tension-release movement is horizontal via a pinion-rack connection and transfer movable slides transversely to the transfer movement.
  • A is described Driving the tensioning mechanism using a DC servo motor, which is stored outside the housing that makes up the lock case and its Rotary motion via a reduction gear and a timing belt with a bevel gear arrangement connected is.
  • This is located on the underside of the housing and has an output shaft for driving the pinion of the pinion-rack combination for the clamping release movement.
  • Japanese Patent Laid-Open JP-A-59-197325 is the drive represented by gripper rails that are moved in two axes.
  • the clamping release movement the gripper rails is operated by a reversible servo motor that is flanged outside a bracket that can be moved horizontally in the direction of movement and must be moved simultaneously with this in the direction of implementation.
  • the motor shaft is one-sided brought out of the motor as a spindle. On the one hand, the spindle on the other hand Right-hand thread on, the cross-movable with the gripper rails Interacting sledges.
  • 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 motion drive the gripper rails are in the middle, but below the gripper rails in one arranged lower part of the lock box.
  • the motor for the tension-release movements the gripper rails between the gripper rails and those carrying them Arrange the carriage so that the size of the tools in the processing stages to be used by the gripper rails when clamping.
  • Claim 2 characterizes an advantageous embodiment according to the invention.
  • the arrangement of the motor at the height of the gripper rails is particularly advantageous and slide, as this creates a direct drive for the clamping and releasing movement realize leaves.
  • the resulting symmetrical design makes the torsional rigidity elevated.
  • the lock box thus forms a functional, complete unit.
  • Lock box 1 of several lock boxes of a multi-column press shown. Of the Only one pair of stands with stand 2 is shown in the press.
  • the lock box 1 is over Console plates 16 set up on the press table side.
  • Helical gears 21 of a motor shaft 19 of a motor 17 for lifting and lowering gripper rails 3.
  • the spur gears 21 interact with a spur gear 22, each directly on a rack 14 guided in frame-side bearings 15 and over another Spur gear 22 acts on a second rack 14 guided in bearings 15.
  • the rotary motion the motor 17 is thus in a lifting-lowering movement (double arrow 28) of carrier plates 13 implemented.
  • the console plates 16 carry a frame 6 in the upper region.
  • the frame 6 is included Provide guides 8 in which the cross slide 7 is displaceable in the tensioning and releasing direction 29 are.
  • the displacement movements of the cross slide 7 are caused by a servo motor mounted in this structure at the level of the cross slide 7 18, whose Shaft is guided out of this on both sides.
  • the shaft parts are with as spindles 23 Right-hand thread or left-hand thread.
  • the threads work with lock nuts 24, 26, cage nuts or the like. Spindle nuts in or on the cross slide 7 together.
  • the movement drive of the gripper rails 3 takes place in the conversion direction 27 z. B. in the manner mentioned from the cited prior art.
  • the lifting-lowering movement 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 spacer bolts 9 the guides 4, for which purpose the guides 12 for the carriage 11 over the Clamp-release movement path of the gripper rails 3 must extend. In the same
  • the guides 8 are also designed in a manner.
