Definitions

  • the invention relates to an upper tool carrier for a punch or the like. According to the preamble of claim 1.
  • the following explanations apply not only to upper tool carriers of machine tools designed as punching dies, but also, for example, when two or more latching tools are arranged next to one another in the upper tool carrier.
  • the teaching of the invention is therefore not only limited to a punch and punching tools, but can also be applied to all machine tools in which comparable problems occur.
  • the teaching of the invention is explained here and below using the preferred exemplary embodiment of an upper tool carrier for a punch in order to facilitate understanding of the teaching.
  • the ends of the punching tools are provided with hammer-head-like extensions and the receptacle and the closure cap are provided with support flanges corresponding to the hammer-head-like extensions, so that the punching tools cannot slide down out of the tool guides.
  • the closure cap is pivoted on the carrier body or on the receptacle via a pivot axis and by means of a locking device, which is arranged on the opposite transverse side, lockable with the support body.
  • the locking device consists of a locking bolt pivotally articulated on the receptacle in the horizontal plane and a locking receptacle provided on the closure cap, which is open on one side, wherein the locking bolt can be pivoted into the locking receptacle and can be tightened by means of a clamping nut.
  • receiving spaces for the upper ends of the punching tools are provided on the carrier body above the tool guides and below a force transmission surface, and these receiving spaces can be bridged by means of force transmission slides which can be displaced essentially perpendicular to the punching direction.
  • Each punching tool is assigned a lifting lever arranged on the carrier body, one end of which laterally grips the upper end of the associated punching tool from below, so that the upper end of the punching tool can be lifted into the receiving space by means of the lifting lever when the power transmission slide is retracted.
  • pneumatic drives or the like which are not to be explained in detail are provided.
  • the above-described upper tool carrier which forms the starting point for the teaching of the invention, can practically no longer be improved with regard to the quick interchangeability of the punching tools.
  • the half-shell design of the receptacle and closure cap to form the tool guides is problematic in practice. If the locking device is too tight, it may happen that the punching tools are clamped in the tool guides. The upper tool carrier is then inoperable. The result is sometimes damaged punching tools and possibly also damaged other machine parts.
  • a continuous mounting plate is provided for receiving the punching tools, in which the tool guides are located. These are vertical closed in a ring shape to the punching direction and the punching tools are pushed in or pulled out in the direction perpendicular to the mounting plate.
  • the mounting plate is pivotally articulated on the carrier body, the stamping tools are exchanged when the mounting plate is pivoted away from the carrier body. This makes it impossible to jam the punching tools.
  • the carrier body is otherwise stationary and the receiving spaces are integrated in the tool guides by the tool guides being particularly elongated.
  • the upper ends of the punching tools are expanded like a hammer head and rest on helical compression springs, which in turn rest on the support flanges.
  • a power transmission slide is pushed between the drive head and the upper end of the punch, which presses the end of the punch down and thereby compresses the helical compression spring to the block length.
  • the clamping of the end of the punching tool between the power transmission slide and helical compression spring thus achieved during punching is not as exact as a clamping between the power transmission slide and the support flange, so that the punching tolerances are relatively large here.
  • the invention is based on the object of designing and developing the known upper tool carrier for a punch or the like without impairing the punching tolerances such that the guidance of the punching tools is unaffected by the attachment of the closure cap to the carrier body.
  • the tool guides are provided completely and closed in a receiving plate, the receiving plate being completely removable from the carrier body.
  • the punching tools can move into the tool guides practically as quickly in the punching direction or in the direction perpendicular to the mounting plate inserted or pulled out of them, as was previously possible with the insertion or removal from the half-shell receptacles. It is impossible to influence the punching tools in the tool guides because the tool guides are closed in a ring on all sides. The cross section of the tool guides in the plane of the mounting plate cannot be changed by the clamping force of the locking device. It is impossible to clamp the punching tools.
  • FIG. 1 shows, as a special, preferred exemplary embodiment of the invention, a machine tool in the form of a hole punch with only one indicated, C-shaped machine body 1, a lower tool carrier 2 formed or arranged on the machine body 1 with a lower tool 3 and an upper tool carrier 4 arranged or executed on the upper side of the machine body 1 with an upper tool, here a punching tool 5.
  • a drive head 6 for example in the form of a hydraulic cylinder-piston arrangement, is seated, with the aid of which the punch 5 can be lowered to the lower tool 3 during operation.
  • the upper tool carrier 4 shown here is characterized in that at least two, to be precise three punching tools 5 arranged next to one another are provided.
  • each punch 5 consists of a punch 7, a punch holder 8 and a union nut 9 connecting the punch 7 to the punch holder 8.
  • the three punch tools 5 are arranged as close as possible to one another, as shown in FIG.
  • Fig. 1 shows that the upper tool carrier 4 in the embodiment shown here initially has a carrier body 10 and a receptacle. 3 makes it clear that tool guides 12 arranged next to one another and extending in the punching direction are provided for each punch 5. 1, 2 and 3 make further clear in connection with this that the upper tool carrier 4 has a closure cap (11) fastened to the carrier body 10, in particular and in the exemplary embodiment shown here pivotable about a pivot axis 13 on the carrier body 10. 1 and 2 finally show in connection that the upper ends of the punching tools 5 in the tool guides 12, limited in one direction by support flanges 15, are guided in the punching direction, here vertically.
  • the support flanges 15 can be clearly seen in FIG. 3. They serve to prevent the punching tools 5 from falling out of the tool guides 12 downwards.
  • receiving spaces 17 for the upper ends of the punching tools 5 are also provided in the upper tool carrier 4 explained here on the carrier body 10 above the tool guides 12 and below a force transmission surface 16.
  • the receiving spaces 17 can be bridged with the aid of force transmission slides 18 or the like, which can be displaced essentially perpendicular to the punching direction, with the aid of actuators 19 designed here as pneumatic cylinder / piston units.
  • the force transmission surface 16 is arranged on the underside of the drive head 6 . This technique ensures that only the punching tool 5 is actively moved downward during the downward stroke of the force transmission surface 16, the force transmission slide 18 of which bridges the associated receiving space 17, while the other two punching tools 5 can move back into the respectively assigned receiving space 17.
  • FIG. 3 of the drawing is characterized in that the receptacle and the closure cap are integrated in a receptacle plate 14 which can be removed from the carrier body 10, that the tool guides 12 are closed in a ring in the plane perpendicular to the punching direction and that the punching tools 5 can be inserted or withdrawn from the tool guides 12 in the punching direction or in the direction perpendicular to the mounting plate 14 when the mounting plate 14 is removed, in particular pivoted, from the mounting body 10.
  • FIG. 3 further shows that, in adaptation to the previously described lifting lever 20 for lifting the ends of the punching tools 5, the receiving plate 14 on the side facing the carrier body 10 on each tool guide 12 has an engagement channel 21 which opens into the tool guide 12 under the support flange 15 has the lifting lever 20.
  • the lifting levers 20 can thus engage through the engagement channels 21 to below the edge of the punching tool 5, in particular the hammer head-like extension at the upper end. This insertion of the lifting lever 20 takes place when the mounting plate 14 is pivotably articulated when the mounting plate 14 is pivoted toward the carrier body 10.
  • the engagement channels 21 in the mounting plate 14 be on the articulation axis 13 for the pivotable articulation on the carrier body 10 facing sides are expanded from the tool guides 12 to the side facing the carrier body 10. This corresponds to the circular arc-shaped movement of the engagement channels 21 about the articulation axis 13.
  • the lateral minimum distance of the articulation axis 13 from the nearest tool guide 12 ensures that the tool guides 12 can be moved far enough away from the carrier body 10 even in the presence of protruding parts of the upper tool carrier 4 in order to completely clear the insertion path for the punching tools 5.
  • the receiving plate 14 can be locked on the carrier body 10 by means of a locking device 22 arranged on the side opposite the articulation axis 13.
  • a locking device 22 arranged on the side opposite the articulation axis 13.
  • 2 and 4 show clearly in the context that according to the preferred teaching of the invention, a second locking device 23 is provided near the articulation axis 13 and, according to the preferred teaching of the invention, below a part 24 located here and extending to the articulation axis 13 the receiving plate 14 is arranged.
  • the locking device 23, like the locking device 22, can be configured in the manner explained in the introduction, namely consist of a locking bolt 25 articulated on the support body 10 in the horizontal plane and a locking receptacle 26 provided on the mounting plate 14 and preferably open on the transverse side , wherein the locking bolt 25 can be pivoted into the locking receptacle 26 and locked by means of a clamping nut 27 or the like.
  • the clamping nut 27 or the like can be designed as a knee clamping lever, as can be seen particularly clearly in FIG. 4.
  • the arrangement of the second locking device 23 below the part 24 of the mounting plate 14 creates the possibility, after the locking bolt 25 has been pivoted away with the clamping nut 27 to the left in FIG. 2, to also open the mounting plate 14 to the left without colliding with the locking device 23.
