Definitions

  • the invention relates to a transfer press with the transfer movement onto the workpieces gripper rails, which can be subdivided into interchangeable gripper rail sections and into presser-side gripper rail sections, with at least on individual, interchangeable gripper rail sections via actuating means in the longitudinal extension of the gripper rails in slidably movable grippers and attached to these.
  • Transfer presses have empty stage areas, in which the workpieces are to be placed without forming.
  • the gripper rails carry grippers which grasp the workpieces in the previous machining stage and convert them into the empty stage area, and grippers which grasp the workpieces in the empty stage region and convert them into the following machining stage.
  • the automation of the gripper change when setting up the transfer press requires the gripper rails carrying the gripper to be moved out.
  • the gripper rails are divided for this. Since the grippers in the empty step areas must also be changed or newly set up, it is advisable to replace them with the extendable gripper rails.
  • JP-A-59 163 037 shows a transfer press according to the preamble of claim 1 with gripper rails which are subdivided into interchangeable and into the gripper rail sections remaining in the transfer press.
  • Means for coupling to one another are introduced in the coupling regions between the gripper rail section.
  • Movable gripper arm holders, each carrying a gripper, are fastened to the exchangeable gripper rail sections in the longitudinal extension of the gripper rails.
  • the gripper arm mounts are attached to slides which can be displaced by means of adjusting means in the longitudinal extension of the gripper rails.
  • the adjusting means are fixed on the interchangeable gripper rail sections. To exchange the gripper rail sections with the grippers and gripper arm holders, these means can be withdrawn onto the interchangeable gripper rail sections.
  • DE-A-33 36 082 shows split gripper rails with grippers that can be raised on the interchangeable gripper rail sections about a horizontal pivot axis that runs transverse to the longitudinal extent of the gripper rails.
  • the construction shown can only be used for short transfer movements and smaller workpieces, since longer gripper arm mounts would collide with the grippers when swiveling out of the empty stage area with the bridge part of the press stand and with the upper part of the tool.
  • the grippers which can be moved in empty-stage areas are pivotally mounted on the slide and the pivot axis runs horizontally and in the direction of the extension of the gripper rails, in that a rotating stall drive, which is operatively connected to the grippers, is fastened, and that the rotary actuators are also mounted the slide and the grippers can be moved out of the empty step area at the same time by means of the adjusting means and can be passed unhindered past the interchangeable gripper rail sections and tool parts.
  • the preferred embodiment according to claim 2 enables force to be applied to the gripper arm holder approximately at the center of gravity of the total mass of the gripper arm holder and grippers.
  • the gripper rail is divided at 3 into an exchangeable gripper rail section 1, which can be pulled out, for example, with a sliding table carrying a tool or a tool set, and into a gripper rail section 2 remaining in the transfer press. This is located in the area of press stands 6.
  • the gripper rail section 1 carries grippers 4 which by means of fasteners 8 fixed, but are interchangeably attached.
  • an actuating means 13 designed as a double-acting pressure cylinder is fastened to the gripper rail section 1, the piston rod 14 of which engages via a fork head 19 and an extension 20 on a slide 18 movable via rail guide means or on a rotary actuator 10 carried by the latter.
  • Bearings 17 are fastened on the carriage 18, in which an axis of rotation 9 of the rotary actuator 10 is mounted.
  • the grippers 5 are fastened to swivel levers 7 by means of fastening means 8 and can be rotated together with the axis of rotation 9 which can be acted upon by the rotary actuator 10.
  • the arrow 15 indicates the interchangeability of the gripper rail section 1.
  • the center line 16 marks the center of the tools. There are usually two gripper rails for moving the workpieces. Double arrow 11 indicates the over-folded position of the grippers 5 when moving out of and into the empty space area between the press stands 6.
  • Query buttons are identified by 12 for monitoring the pivoting position of the grippers 5 and 21 query buttons for the movement of the carriage 18 from the empty stage area or in this.
