Definitions

  • the invention relates to a press for deep drawing with a from a ram moving tool part, one in the same direction moving, press-side sheet metal holder and a die Board supporting tool lower part in the the upper part of the tool transforms the blank into a deep-drawn part immersed, the upper and lower parts of the tool against Tools of other contours are interchangeable and that Tool upper part whose contour follows the tool side Interchangeable sheet holder is associated with the press-side sheet metal holder is operatively connected.
  • Deep-drawing presses in the sense of the invention are mechanical and hydraulic, as well as hydro-mechanical acting Presses understood.
  • top part and lower part of the tool the complete shape of the deep-drawn part on, while with hydro-mechanical presses only the upper part of the tool has the contour and the forming force is generated via a hydraulic medium.
  • this connection serves as the lower part of the tool for the hydraulic medium receiving water box and a shape contour Contour plate that determines the lead-in area of the board.
  • the preamble of claim 1 is the object of the invention solved in that the press-side sheet metal holder sheet metal holder segments recessed flush into its face having horizontal along a common axis movable and with their facing each other Sides are adjustable to the contour of the tool, and that the associated tool-side sheet metal holder at least the sheet metal holder segments are exchangeably attached.
  • the sheet metal holder on the tool side which as a closed, rigid frame can be formed and on the contour of the respective upper part of the tool is matched Only function adequately if the forces of the press-side sheet holder come into effect accordingly can.
  • the sheet metal holding forces can be local transmitted where they are needed, namely immediately on the contour of the upper part of the tool or in the infeed area of the sheet in the lower part of the tool.
  • the training according to the invention in particular leaves a relative great variability in an axis perpendicular to the movement axis the plunger.
  • the range of variation is smaller, but also given as in known versions. In any case, for one optimal power flow with a wide range of variations, if the tool-side sheet metal holder is with its back both on the sheet metal holder segments and on the Front of the press-side sheet metal holder outside of the Supported segments.
  • the replaceable ones are Tool upper parts for the transfer of the pressing force equipped with a variety of pressure pins that are constructive elaborate and space-consuming and also difficult to assemble are.
  • the invention remedies that a force-transmitting between the ram and the upper part of the tool Intermediate piece is arranged, which consists of a central, tappet-proof pressure piece and two with the sheet metal holder segments pressure pieces that can be moved in the same direction exists, which can be adjusted to the contour of the upper part of the tool are.
  • Thrust pieces need on the exchangeable upper part of the tool no noteworthy constructive arrangements for the interchangeability can be made and the Push pins and their complex assembly. Let also the pressing forces through the central pressure piece and through on the contour of the interchangeable upper part of the tool adjustable pressure pieces in a favorable way, especially in the near-contour area.
  • the upper part of the tool is on the tappet-proof pressure piece interchangeably attached and supported on the sliding Pressure pieces essentially free of play, so that in central area avoiding an immediate flow of force guided tours is guaranteed.
  • This can still be done be optimized that with a wider range of variations of the tools, the central pressure piece on the ram can be replaced and is adaptable to the tool size, so that the displaceable pressure pieces essentially only for power transmission serve in the area close to the contour.
  • the invention also gives the possibility of the tool upper parts easy to design as a stamp.
  • the deep-drawing press used in the context of the invention has an essentially conventional structure, which is why only those essential for understanding the invention Components are shown, namely the plunger 1 (inner plunger), the sheet metal holder 2 and the press table 3.
  • the ram 1 and the sheet metal holder 2 on the press side is moved in the same direction - down in the drawing.
  • the lower tool part 4 sits Molding surface of the outer surface of the deep-drawn part to be produced equivalent. According to the open position 1 is inserted a plate 6 made of sheet metal, which on the Edge 5 of the lower tool part 4 rests.
  • a tool upper part 7 is assigned to the lower tool part 4, that in the embodiment shown as easier Form stamp is formed, the shaped surface of the inner surface corresponds to the deep-drawn part to be manufactured.
  • the Lower tool part 4 and upper tool part 7 are against Interchangeable tools with a different shape.
  • the tool upper part 7 is also an interchangeable Sheet metal holder 8 - the sheet metal holder on the tool side - assigned, which is adapted to the contour of the tool upper part 7 is and can be designed as a rigid frame.
  • the tool side Sheet metal holder 8 forms with its end face 9 the sheet holding surface.
  • the sheet metal holder 2 on the press side has on its end face 10 opposite guides 11, 12 in the sheet metal holder segments 13, 14 are embedded flush, see above that their facing the tool-side sheet holder 8 Surfaces 15, 16 with the face 10 of the press side Sheet metal holder 2 formed surface form a plane.
  • the sheet metal holder segments 13, 14 are in the guides 11, 12 of the press-side sheet metal holder 2 according to the shown in Figure 3 double arrows and with their facing each other on the contour of the inserted Tool upper part 7 adjustable so that the sheet metal holding force from the press-side plate holder 2 via the plate holder segments 14 without significant force redirection in the tool-side sheet holder 8 and thus on the inlet area the board is transferred.
  • a variable intermediate piece for power transmission arranged that from a central and with the pestle 1 firmly connected pressure piece 17 with a relatively large Power transmission surface and sliding pressure pieces 18, 19, of which only two are shown as examples are.
  • the pressure pieces 18, 19 are together with the sheet metal holder segments 13, 14 displaceable and on the outer contour of the tool upper part 7 adjustable to a cheap Allow power transmission.
  • the tool-side sheet metal holder 8 is dash-dotted in FIG played. It is at least on the sliding Sheet holder segments 13, 14 interchangeably attached and supports itself with its outside the sheet metal holding segments surfaces on the front side 10 of the press side Sheet holder 2 from. If necessary, can still there releasable fastenings may be provided.
  • the tool upper part 21 is a tool-side one Sheet holder 22 assigned to the at least on the sheet holder segments 13, 14 is releasably attached.
  • This frame-like, tool-side sheet holder 22 is supported with its lying outside the sheet metal holder segments 13, 14, back surfaces in turn on the press-side sheet holder 2, as in Fig. 6 on the dash-dotted lines recognizable.
  • the sheet metal holder segments 13, 14 are in front of the Attachment of the sheet metal holder 2 on the tool Contour of the tool upper part 21 set.
  • the matching tool lower part 23 is mounted, on the Edge 24 of the board 25 rests.
  • the central pressure piece 17 are in turn the displaceable Pressure pieces 18, 19 assigned to the compared to Fig.1 shifted inside and adjusted to the contour of tool 2 are. Both the setting of the sheet metal holder segments 13, 14, as well as the displaceable pressure pieces 18, 19 happens before the tool is installed. Together with the sheet metal holder segments 13, 14 are the pressure pieces 18, 19 adjusted to the contour of the tool. Only afterwards the sheet metal holder 22 on the tool side is mounted.
  • the further mode of operation corresponds to that in relation to FIG. 1 to 3 described, so that finally a deep-drawn part 26th other form is obtained.
  • the central pressure piece 17 on the tappet 1 interchangeably attached to it against another central thrust piece with a suitable area ratio replace the upper part of the tool.
  • the. shiftable Pressure pieces can be interchangeable if necessary.
