Definitions

  • the invention relates to a gripper feed device for the intermittent feed of strip or wire material on presses, punches or the like. Working machines.
  • Plier feeds according to DE-A-21 58-777 and DE-A-2659156 are known for these purposes, which have a reciprocating transport pliers and a stationary holding pliers, both pliers of which are controlled in phase opposition in their opening-closing movement in a slide arrangement the transport tongs behind the holding tongs, the carriage being drivable by the overall drive with the transport tongs.
  • a sliding block is present in the feed drive, which can be displaced for stroke adjustment.
  • the adjusting spindle for the sliding block also rotates, so that the feed can only be adjusted when it is at a standstill. If changes are made to the run and the sequence of steps, adjustments during the run are desirable.
  • Working machines which also adjust the feed length from the outside during allows operation, either by hand or by means of an adjustment motor, also using microcomputers and, moreover, enables the transport and holding tongs to be automatically adapted to the material thickness of the strip or wire material to be fed.
  • the pliers feed device for the intermittent feed of strip or wire material on presses, punching or the like.
  • Working machines according to the preamble of claim 1 are characterized according to the invention in that the sliding block forms the fulcrum of a pendulum frame lying transversely to the slide movement, the sliding block at The current pliers feed can be moved by means of the spindle via the slide which is guided on the device housing to the slide and on which the sliding block is seated by means of a pivot bearing, while the pendulum frame with adjustable sliding block on one end bearing can be made to oscillate from the entire drive by means of a swiveling pivot finger and on the second end bearing holds the carriage forward and backward via a tab.
  • an adjustment of the feed length is made possible during operation from the outside, namely manually or by motor, e.g. B. by means of spindle adjustment of the sliding block.
  • This means that an automatic correction can also be carried out using a measuring system with a microcomputer.
  • a bearing arm on the slide can form the movable clamping jaws of the transport tongs and the bearing arm can be brought into the closed and open position by pistons supported on a rocker, for which purpose a cam disc acting on this rocker on the other controls the pincer opening via this rocker and a bearing rocker on Device housing forms the movable clamping jaws of the holding pliers, one of which seesaw arm can be brought into the closed and open position by pistons supported on a rocker, for which purpose a cam disc acting on this closing rocker controls the opening of the pliers via this rocker.
  • an adjusting shaft driven by the overall drive with a cam disk that can be moved and rotated for the actuation of the transport pliers and a cam disk that is fixed and rotatable for the actuation of the holding pliers also serves as a slide guide with an additional, parallel guide rod, the ones supported on the rocker switches in the respective one Bearing arm or rocker arm-engaging pistons act on the transport or holding jaws for closing and opening with the interposition of pressure springs in order to achieve their transport and holding system regardless of the material thickness.
  • the pliers feed device is driven from the main shaft of the working machine via angular drives with an intermediate telescopic shaft in the machine rhythm for conversion into an intermittent feed movement for strip or wire material 1.
  • a reciprocating transport pliers 2 with the clamping jaws 2a, 2b by means of a bearing arm 3 are Carriage 4 and a stationary holding pliers 5 with the clamping jaws 5a, 5b are provided on the device housing 7 by means of a rocker 6.
  • the reciprocating drive of the carriage 4 with the transport tongs 2 takes place, as can be seen in particular from FIGS.
  • the bearing arm 3 on the carriage 4 forms the movable clamping jaw 2b of the transport rod 2, the bearing arm 3 being able to be brought into the closed and open position by pistons 16 supported on the one side by a closing lip 15, for which purpose one on this rocker 15 on the other hand acting cam 17 takes control.
  • the bearing rocker 6 on the device housing 7 forms the movable clamping jaws 5b of the holding jaws 5, the one rocker arm 6a in turn being able to be brought into the closed and open position by pistons 19 supported on the one side on a rocker switch 18, for which purpose a cam 20 acting on this rocker on the other hand is also used here control takes over.
  • the adjusting shaft 21 is also driven via toothed belts 8a, on which both the displaceable and rotatable cam disk 17 and the fixed and rotatable cam disk 20 are seated.
  • the cam disc 17 is held by a rotating ball wedge 22 so that it can be moved and rotated, so that the slider can be moved, while the cam 20 is held by the wedge 23 so that it cannot be moved.
  • the adjusting shaft 21 with the parallel guide rod 24 also serves to guide the slide.
  • the pistons 16, 19, supported on the rockers 15, 18 and engaging in the respective bearing arm 3 or inner arm 6a are equipped for closing and opening with interposed stop-limited compression springs 25, 26 for the transport or holding jaws 2b, 5b. In this way, regardless of the thickness of the strip or wire material 1 to be advanced in batches, a transport and holding system which is always perfect is achieved, which, as desired, increases with strong material 1 as a result of the compression springs 25, 26 used.
  • the bearing rocker 6 on the second rocker arm 6b is also brought into a superimposable open position for ventilation of the holding pliers 5 by pistons 28 supported on the one hand on a lifting rocker 27, for which purpose a cam disk 29, which also acts on the lifting rocker 27 and also sits on the shaft 21, which Forceps opening serves for ventilation.
  • the release rocker 27 can be turned and adjusted by means of an eccentric bearing 30 via an actuating piston 31, as can be seen in FIG. 7.
  • the piston 28, which is supported on the rocker arm 27 and engages in the second rocker arm 6b, is held by an interposed compression spring 32 with travel limit 33, where the rocker switch 18 is released when the rocker arm 27 is actuated.
  • Intermediate ventilation is only required when working with search pins to align the strip material.
  • the pivoting finger 9 moved by the cam drive 8 for the pendulum frame 10 has resting phases between the alternating pendulum movements, i. H. between the back and forth movements of the slide 4.
  • the cam disks 17, 20 and 29 driven by the toothed belt 8a on the control shaft 21 cause the alternating actuation of the transport and holding forceps 2.5 via the rocker 15, 18 and the switchable Release rocker 27.
  • a safe band clamping is guaranteed by covering the opening and closing movements of the pliers 2,5 in the resting phase.
  • the upper fixed clamping jaws 2a, 5a which act as counter-holding jaws of the transport and holding tongs 2.5, are attached to bridges 34, 35 for the joint ventilation of the tongs 2.5 by means of pneumatically actuated pistons 36, 37, which are each connected via cross members 38, 39 are and can be brought into the starting position via spring guide pins 40 after ventilation.
