Definitions

  • the invention relates to a device for coupling and uncoupling gripper rail sections of a transfer press, with to bridge the joint between the end parts of the gripper rail sections from one gripper rail section into the other gripper rail section movable clamping elements and movable from the clamping elements transversely to their direction of displacement, and with a clamping means for the Movement of the clamping elements in and against the direction of displacement.
  • the gripper-bearing gripper rail sections are set up for the transport of the workpiece to be subsequently manufactured and exchanged with the tool change. These interchangeable gripper rail sections are to be coupled to the press-side gripper rail sections remaining in the transfer press to form a rigid structure. Coupling and uncoupling is automatic. A parting line remains between the gripper rail sections to be coupled together. The components causing the coupling and uncoupling status are located in the press-side gripper rail sections.
  • a generic term-forming device has been described in DE-A-33 00 227.
  • the device comprises hollow profile pieces fastened to the end faces of the mutually facing ends of the gripper rail sections.
  • An expanding mandrel which can be moved axially into the other hollow profile piece is arranged in a hollow profile piece.
  • the expanding mandrel has a spindle which can be rotated from outside the gripper rail section and which is axially adjustable baren interacts.
  • the sleeve carries expanding mandrel members, the distance between which decreases when the sleeve abuts against a spindle-fixed stop.
  • the parting line is closed by pressure pieces and the flow of force runs through the outer wall of each gripper rail part and a rigid clamping element.
  • the parting line is closed before the ends of the gripper rail sections are pressed together.
  • gripper rail sections 1 and 2 are shown, which are in a coupling position.
  • the coupling position is achieved in that the exchangeable gripper rail section 2, which can be moved, for example, with the sliding table of the transfer press, is moved by hydraulic means into a position in alignment with the gripper rail section 1, which remains in the transfer press.
  • the gripper rail section 1 has in its end region a base plate 3 and a housing 4, these means being releasably fastened by means of screws 5.
  • a clamping means 9 is flanged to the base plate 3.
  • the clamping means 9 is supported in a bearing plate 10.
  • the clamping means 9 can be controlled hydraulically, pneumatically or electrically in such a way that a clamping bolt 11 can be adjusted in a displacement direction 26, upper arrow, and in an opposite displacement direction, lower arrow, and in a rotary movement 28.
  • a clamping means 9 is a rotary tensioner and is commercially available.
  • the clamping bolt 11 is provided with a shoulder 13 in the area near the clamping device and with a clamping anchor 12 in the end area remote from the clamping device.
  • the lug 13 can be placed with the interposition of a thrust washer 16 when the clamping bolt 11 is displaced against a slider 14 shown in more detail in FIG. 2.
  • the tension anchor 12 is after advancing in the direction of displacement 26 - upper arrow - a rotation 28 by 90 degrees and a retraction against the direction of displacement 26 - lower arrow - against a ball socket 20 in a screw 8 and one end plate 6 attached to the end portion of the interchangeable gripper rail section 2 housing 7.
  • the position of the tension anchor 12 rotated by 90 ° is identified by 12 '.
  • the housing 7 has an elongated opening 19 in the form of the cross section of the tension anchor 12 for the passage of the tension anchor 12. Stop pieces 18 are screwed into an extension 29 in the end face of the housing 7.
  • a pressure piece 21 can be inserted into the guide grooves 25, which have corresponding counter-forms in the guide areas.
  • the pressure pieces 21 are secured by end plates 17 in the slide 14.
  • the gripping rail sections 1 and 2 are clamped together by rotation, arrow 28, and retraction of the clamping bolt 11 in the direction of displacement 26, lower arrow, with the clamping anchor 12 resting against the ball socket 20, FIG. 3, lower half of the drawing.
  • FIG. 4 shows the opening 19 in the housing 7 for the passage of the tension anchor 12, the tension anchor 12 rotated into the rotational position 12 ′ and the stop pieces 18 in a broken line.
  • These stop pieces 18 are kept smaller in cross section than the cross section of the guide groove 25 in the slider 14, so as to allow the slider 14 to move further after the pressure pieces 21 bear against the stop pieces 18.
