Definitions

  • the invention relates to a press with a workpiece ejecting device and a closing height adjusting device, at least one ejector being present which is guided through the closing height adjusting device and the closing height adjusting device has a support plate and a wedge interacting with it via wedge surfaces, which is vertical is displaceable to the tappet movement direction and which is provided with a cavity for the passage of the ejector, the cavity being elongated for the adjustment of the wedge.
  • Presses include ram-side or table-side pressure adjustment or stroke adjustment devices, which often bring about the press pressure during massive forming or the closing height for the tool via a wedge adjustment device.
  • embossing presses it is necessary to achieve the optimal design of the engraving of the embossed part via the pressure setting device.
  • the embossed part is ejected via an ejector mechanism, which, according to e.g. B. the tool change in its stroke length and in its stroke position on the workpiece to be ejected or the forming tool.
  • Such a device is described in DE-A1-2530400 with a frame which is fixedly arranged on the press table.
  • the frame has a wedge-shaped extension on which a wedge rests with its wedge surface, which can be adjusted on the slope of the extension and with respect to the direction of adjustment when it moves in its longitudinal axis.
  • the movement in the direction of adjustment is transmitted to a cover plate which is guided laterally on the neck of the frame.
  • the wedge is adjusted via a screw drive.
  • An ejector rod is passed through this closing height adjusting device.
  • the wedge is expanded in the lead-through area of the ejector rod for an adjustment movement transverse to the ejector movement by a recess. After each adjustment of the wedge transversely to the direction of ejector movement and fixing the position after z.
  • B. a tool change a readjustment of at least the position of the ejector stroke is required.
  • the cavity in the wedge is expanded to accommodate an intermediate wedge and the intermediate wedge is displaceably guided in this in the ejection movement direction, that the wedge and intermediate wedge have support surfaces for support and sliding guidance on at least one support surface of the closing height adjusting device perpendicular to the tappet movement direction, that the intermediate wedge has at least one wedge surface parallel to the wedge surface on the wedge, and that the ejector rod is designed to be split, the resulting end piece of the ejector rod driven by an ejector drive being slidable on the supporting surface of the intermediate wedge and movingly engaging the intermediate wedge in the ejection movement direction and the resulting end piece of the ejector rod, which interacts with the workpieces to be ejected from the tool, is slidable on the wedge surface of the intermediate wedge and under the action of the wedge surface in the ejection direction of movement is movably supported.
  • a pressure adjustment device or a closing height adjustment device in presses of various applications, e.g. B. as an embossing press, as a deep-drawing press or as a punch press, enables the upper and lower tool parts to be fed to one another independently of the ram movement required for the forming process.
  • the drawing shows a pressure adjustment device placed on the press table, the measures described can also be used with the same effect when the pressure adjustment device is attached to the ram direction as well as for presses with horizontal or deviating ram movement.
  • the pressure adjustment device (Fig. 1 and 3) comprises a frame 2, which is clamped on the indicated press table 1.
  • a support plate 4 designed in the manner of a clamping table for the indicated tool part 6 is movably mounted in the frame frame 2 in vertically extending slide guides 13 in the direction of pressure adjustment or closing height movement 27.
  • a wedge 3 is introduced, which is displaceable in the directions of the double arrow 28 via a spindle drive 9, 11.
  • the wedge 3 slides over its support surface 18 on the support surface 17 of the frame 2, while the relative movement of the wedge surface 14 on the wedge 3 and the wedge surface 16 on the support plate 4 moves the support plate 4 in the directions of the double arrow 27.
  • one or more ejector rods 7, 8 are each movably mounted in and against the ejection movement direction 29.
  • the ejector rod 7, which originally formed a component with the ejector rod 8, is driven in a known manner via an ejector drive for executing the ejector movement in the direction of the arrow 29.
  • the tool-side ejector rod 8 transmits the ejector movement to, for example, a pressure plate in the tool 6.
  • an intermediate wedge 12 which is located in the enlarged cavity 5 of the wedge 3 in and against the ejection movement direction 29 and with this in the arrow direction 28 is displaceable. To adjust the height of the intermediate wedge 12 in the cavity 5, it slides with lateral running surfaces 21 on parallel running surfaces 19 of the wedge 3.
  • the intermediate wedge 12 can be provided with an opening 24 for the passage of the spindle 9, which is threadedly mounted in the wedge 3 at 22.
  • the articulated ejector rod 7 is supported on the support surface 30 of the intermediate wedge 12 via the flat end 32.
  • the tool-side ejector rod 8 is placed against an inclined surface 31 which extends at the same angle as the wedge surface 14 on the wedge 3.
  • the end of the tool-side ejector rod 8 is, for example, spherically shaped in the support surface 33 in order to slide on the wedge surface 31 if the wedge 3 is adjusted.
  • the rod end has a flat edge 26 against twisting when the support surface 33 is chamfered.
  • the ejector rod 8 on the tool side is raised to the same extent as the support plate 4 and vice versa .
  • the support plate 4 slides in the slide guides 13 and the intermediate wedge 12 via the wedge surface 31 on the running surface 33 of the tool-side ejector rod 8.
  • the intermediate wedge 12 can be raised via the articulated ejector rod 7. The lifting movement is thus transferred to the tool-side ejector rod 8.
  • the intermediate wedge 12 which is otherwise positioned with the same reference numbers taken from FIGS. 1 and 3, has a groove 34, which extends on both sides of the longitudinal direction of the intermediate wedge 3, for guiding the tool-side ejector rods 8, in the groove base 35 thereof, in the same way as the wedge surface 31 of FIGS. 1 and 3 runs obliquely, the tool-side ejector rods 8 are slidably supported.
  • Several intermediate wedges 12 can be formed and displaceable in the wedge 3 in the manner described above.
