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 clinker 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 mounting plate 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 pivotably articulated on the carrier body or on the receiving plate via a pivot axis and can be locked with the carrier body or the receiving plate by means of a locking device which is arranged on the opposite transverse side.
  • the locking device consists of one on the Take plate in the horizontal plane pivotally hinged bolt and a provided on the closure cap, one-sided open bolt receptacle, wherein the locking bolt can be pivoted into the bolt receptacle and clamped 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 raised into the cavity 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 mounting plate and the closure cap for forming the tool guides is problematic in practice. If the locking device is too tight, it can 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.
  • the invention is based on the object of designing and developing the known upper tool carrier for a punch or the like so that the guidance of the stamping tools is unaffected by the attachment of the closure cap to the carrier body.
  • the upper tool carrier according to the invention in which the above-mentioned object is achieved, is described by the features of the characterizing part of claim 1.
  • the factory is assumed Tool guides each half-shell like part in the cap, to be provided in part in the mounting plate. Rather, according to the invention, the tool guides are provided completely and closed in the mounting plate, the mounting plate now being part of the closure cap and thus being completely removable from the carrier body.
  • the punching tools can be inserted or removed from the tool guides practically as quickly in the punching direction or in the direction perpendicular to the receiving plate as was previously possible with the insertion or removal from the half-shell receptacles .
  • FIG. 1 shows, as a special, preferred exemplary embodiment of the invention, a machine tool in the form of a hole punch with a C-shaped machine body 1, only indicated, a lower tool carrier 2 formed or arranged on the machine body 1 with a lower tool 3 and one on the machine body 1 arranged or executed top tool carrier 4 with an upper tool, here a punching tool 5.
  • a drive head 6, for example in the form of a hydraulic cylinder piston Arrangement sits, with the help 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 here side by side 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 punching tools 5, as shown in FIG. 2, are arranged as close as possible to one another.
  • Fig. 1 shows that the upper tool carrier 5 in the embodiment shown here initially has a carrier body 10 and a receiving plate 11.
  • Fig. 3 makes it clear that in the mounting plate 11 side by side, extending in the punching direction tool guides 12 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 14 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 punch 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 3 shows well. 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 provided 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 that punch 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.
  • closure cap 14 includes the mounting plate 11, that the tool guides 12 are closed in a ring in the plane perpendicular to the punching direction and that the punching tools 5 at Carrier body 10 of removed, in particular pivoted, closure cap 14 can be inserted or withdrawn from tool guides 12 in the punching direction or in the direction perpendicular to receiving plate 11.
  • Fig. 3 further shows that in adaptation to the previously described lifting lever 20 for lifting the ends of the punching tools 5, the closure cap 14 on the side facing the carrier body 10 on each tool guide 12 has an engaging channel 21 for the tool guide 12 opening under the support flange 15 has the lifting lever 20.
  • the lifting levers 20 can 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 with the pivotable articulation of the closure cap 14 by itself when the closure cap 14 is pivoted toward the carrier body 10.
  • the center point in the preferred embodiment shown and shown here the articulation axis 13 for the articulation of the closure cap 14 on the carrier body 10 is arranged laterally at a considerable distance, preferably at a distance of approximately 100 mm to 200 mm, in particular approximately 150 mm, from the nearest edge of the nearest tool guide 12.
  • This laterally cantilever-like construction of the carrier body 10 and the closure cap 14 has the advantage that the upper ends of the punching tools 5 can easily be pulled up out of the tool guides 12 in the mounting plate 11.
  • the lateral minimum distance of the articulation axis 13 from the closest 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 projecting parts of the upper tool carrier 4 in order to completely clear the insertion path for the punching tools 5.
  • the closure cap 14 can be locked on the carrier body 10 by means of a locking device 22, in particular a locking device 22 arranged on the side opposite the articulation axis 13. 2 and 4 clearly show 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 cap 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 carrier body 10 in the horizontal plane and a locking receptacle 26 provided on the locking cap 14, preferably open on one side and 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 closure cap 14 creates the possibility, after pivoting the locking bolt 25 with the clamping nut 27 to the left in FIG. 2, to also pivot the closure cap 14 to the left without colliding with the locking device 23.
