Definitions

  • the invention relates to a transfer press with the transfer movement to the workpieces gripper rails, which can be subdivided into interchangeable gripper rail sections and press-side gripper rail sections, with at least on individual, interchangeable gripper rail sections by means of adjusting means in the longitudinal extension of the gripper rails in gripper arm holders which can be moved on gripper arm holders which are movable in empty step areas of the transfer press.
  • 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.
  • DE-PS 32 33 102 shows a transfer press with gripper rails, which are subdivided into interchangeable and remaining in the transfer press gripper rail sections.
  • Means for coupling the gripper rail sections together are introduced into the press-side gripper rail sections.
  • the interchangeable gripper rail sections are in the longitudinal direction of the gripper rail movable gripper arm brackets carrying a gripper. The adjustment of each gripper arm holder into the empty stage of the transfer press and out of the empty stage is dependent on the coupling movement of the gripper rail sections, and the gripper in the empty stage cannot be guided past the first gripper, for example, attached to the extendable gripper rail section.
  • the grippers which can be moved in empty stage areas are pivotally mounted on the gripper arm holders and the pivot axis runs horizontally and in the direction of the extension of the gripper rails, that a rotary actuator which is operatively connected to the grippers is attached to the gripper arms, and that the rotary actuators are mounted with the gripper arm mounts and the grippers can be moved out of the empty space area at the same time by means of the adjusting means.
  • 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 into an interchangeable, e.g. With a sliding table carrying a tool or a tool set, the gripper rail section 1 can be moved out 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 are fastened by means of fastening means 8, but are replaceable.
  • 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.
  • the carriage 18, which is used to hold the gripper arm, can be moved via the separating area 3 by means of the adjusting means 13.
  • 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 points to the Uber-up position of the grippers 5 when moving out of and into the empty space area between the press stands 6. With 12, query buttons are identified for monitoring the pivoting position of the grippers 5 and with 21 query buttons for the movement of the slide 18 from the empty space area or in this.
