Definitions

  • the invention relates to a lower tool carrier for a punch or the like according to the preamble of claim 1.
  • the known lower tool carrier from which the invention is based (brochure "MUBEA KBLH HYDRAULIC" and DE-OS 34 32 671) has a tool saddle, which is a saddle-like structure from above, which is made in one piece with the machine body of the punch covered with two side cheeks.
  • the base frame can have punch supports projecting upwards, on which a part of the tool saddle projecting like a cantilever is supported vertically. The punching forces that occur are thus diverted into the machine body.
  • the tool saddle can, however, also be designed like a plate, in which case a tool holder with an exchangeable standard tool holder may be provided. It is essential that the tool saddle can be moved relative to the base frame on the saddle surface by means of the adjusting devices, so that it can be set up relative to an upper tool.
  • the adjustment devices for the tool saddle of the known lower tool holder are still too complicated to use. To reset the tool saddle, the holding device must first be released and then two transverse adjustments and two longitudinal adjustments must be released, adjusted and locked again. Finally, the holding device must be locked again.
  • the invention is therefore based on the object of improving or simplifying the known lower tool carrier with regard to the attachment of the tool saddle.
  • the holding device of the lower tool carrier according to the invention no longer has to be released and locked in relation to the base frame for re-setting the tool saddle. Rather, the holding device only serves to hold the tool saddle the saddle surface in the vertical direction and the formation of a guide for the tool saddle on the saddle surface in the plane of the saddle surface. It has been recognized that with this construction of the holding device, the adjusting devices can be locked sufficiently well to achieve a completely satisfactory fixation of the tool saddle on the underframe during operation. However, special configurations of the transverse adjustments and the longitudinal adjustment are expedient, for which purpose reference should be made to claims 2 and 4.
  • the C-shaped machine body 1 with an upper tool 2 attached to it can be clearly seen here.
  • the machine body 1 forms a lower tool carrier 3 in the lower part.
  • game is a punch, namely a hole punch, but the teaching of the invention can be applied to all other types of lower tool carriers 3 for machine tools.
  • the lower tool carrier 3 initially has a base frame 4 with an end face S, long sides and a rear side facing the machine body 1.
  • a tool saddle 6 with a saddle plate 7 is slidably arranged on a saddle surface 5 of the base frame 4.
  • the tool saddle 6, as is known per se, from the saddle plate 7 has a U-shaped downward-facing side flange 8 and, in the exemplary embodiment of a hole punch, an obliquely upward-projecting tool arm supported on supports 9 of the underframe 4 in the vertical direction 10 on.
  • adjustment devices 11, 12 for adjusting the tool saddle 6 relative to the base frame 4 in the plane of the saddle surface 5 and a holding device 13 for holding the tool saddle 6 on the base frame 4 can be seen or indicated, however, cannot be seen in FIG.
  • the saddle plate 7 of the tool saddle 6 has at least one lower flange 14 and the holding device has at least one holding flange 15 which positively encompasses the lower flange 14, the holding flange 15 in the plane of the saddle surface 5 has a precisely determined relative position to the base frame 4 and so the saddle plate 7 or Tool saddle 6 is secured against vertical lifting off the saddle surface 5 on the base frame 4. 2 of the drawing shows these details better than FIG. 1.
  • FIG. 1 and 2 show in the context that in the embodiment shown here the vertical distance of the holding flange 15 of the holding device 13 from the saddle surface 5 of the base frame 4 is exactly predetermined, and is somewhat larger than the thickness of the lower flange 14 of the saddle plate 7 It is thereby achieved that lifting the tool saddle 6 from the saddle surface 5 in the vertical direction is made impossible by the holding flange 15 or the holding flanges 15 of the holding device 13, but that in the plane of the saddle surface 5 the saddle plate 7 with the tool saddle 6 is entirely is movable.
  • the adjustment and locking in the plane of the saddle surface 5 is only a task according to the teaching of the invention of the adjusting devices 11, 12, no longer of the holding device 13. As a result, when the tool saddle 6 is newly set up, there is no need to loosen and re-lock the holding device 13.
  • Fig. 1 now makes further clear that two transverse adjustments 11 are provided on each longitudinal side of the tool saddle 6 and two transverse adjustments 11 are arranged opposite each other near the end face S of the tool saddle 6 and near the rear of the tool saddle 6.
  • the cross-adjustments 11 also have a threaded shaft 16 screwed into a threaded bore in the tool saddle 6, butting against the base frame 4, and a rocker arm 17 is attached to the end of each threaded shaft 16.
  • Tilting tension levers 17 have the advantage over normal hexagon screws that they can be operated quickly without tools.
  • transverse adjustments 11 A quick adjustment is thus ensured for the transverse adjustments 11, namely that only the transverse adjustments 11 or their rocker arm 17 opposite each other in pairs need to be pivoted in the same direction in order to adjust the tool saddle 6 in the transverse direction.
  • the four provided transverse adjustments 11 also allow a slight inclination of the tool saddle 6, so that this saddle quick adjustment is associated with a particularly large number of degrees of freedom.
  • the holding flange 15 and the saddle surface 5 form a sliding seat, on the one hand, with the lower flange 14, in particular with a tolerance of + 0.05 mm.
  • two holding flanges 15 are arranged in the longitudinal direction of the saddle plate 7 and each cover one of two lower flanges 14 arranged on the saddle plate 7. This construction ensures a particularly safe, symmetrical distribution of the forces occurring in the holding device 13.
  • the cover plate 18 is then of course in some way to be connected to the base frame 4, for which purpose it is particularly useful that, as in the 2 to 4 can be clearly seen, the cover plate 18 is connected to the saddle surface 5 by at least one retaining screw 19, preferably two retaining screws 19, and that the head of each retaining screw 19 can be pulled up to the saddle surface 5 to a precisely predetermined distance.
  • the distance to which the head of each retaining screw 19 can be drawn to the saddle surface 5 results from the requirement mentioned in claim 1 that the distance of the retaining flange 15 from the saddle surface 5 is somewhat larger than the thickness of the lower flange 14 of the saddle plate 7, so that in particular the sliding seat mentioned in claim 5 is formed.
  • the spacing of the heads of the retaining screws 19 can be achieved in particular in that a corresponding threaded hole in the base frame 4 has a very specific depth for each retaining screw 19, so that the retaining screw 19 is precisely determined with regard to the screw-in depth. Then the cover plate 18 is arranged, so to speak, "floating" on the saddle surface 5 or the lower flanges 14 of the tool saddle 6.
  • each retaining screw 19 is surrounded by a spacer sleeve 20 in the region of the saddle plate 7 and the length of the spacer sleeve 20 is slightly greater than the thickness of the saddle plate 7 or the lower flanges 14
  • the cover plate 18 does not "float" on the saddle plate 7 or the lower flanges 14, but is firmly clamped to the base frame by means of the retaining screws 19 and the spacer sleeves 20.
  • the retaining screws 19 should be seated in the cover plate 18 in a snug fit, in the preferred embodiment shown here, the retaining screws 19 are designed as Allen screws. In this way, the cover plate 18 has an absolutely fixed and precisely determined relative position with respect to the saddle surface 5.
  • the lower flanges 14 of the tool saddle 6 are not elongated flanges running in the longitudinal direction, but are, as it were, formed in the saddle plate 7 which is designed continuously.
  • the saddle plate 7 has a push-through opening 21 for each stop in order to form the lower flanges 14 screw 19 and that, preferably, the push-through opening 21 is designed as an elongated hole or as a hole of larger diameter.
  • the longitudinal adjustment 12 has a threaded bore 22 arranged in the tool saddle 6 and starting from the end face S and a threaded shaft 23 screwed into the threaded bore 22 and that the threaded shaft 23 has a holding flange 15 at its rear end, in particular with the cover plate 18 , rotatable, but axially firmly coupled.
  • the threaded shaft 23 is designed as a grub screw, in particular as a slotted grub screw. Otherwise, it can be seen that the threaded shaft 23 carries a lock nut 24 or the like on the side facing the rear end. The lock nut 24 serves to lock the longitudinal adjustment 12.
  • Fig. 3 makes it particularly clear that in the embodiment shown here between the tool saddle 6 and the holding flange 15 or the cover plate 18 there is a space accessible from above for actuating the lock nut 24.
  • the coupling devices explained above are particularly designed in the preferred embodiment shown here so that the holding flange 15 or the cover plate 18 has a transverse groove 26 which is open towards the front side S, in particular a T-groove or dovetail groove, and the rear end of the Threaded shaft 23 is provided with a corresponding sliding block 27. It also applies here that a rotary socket pivotable about axis 25 is mounted on the sliding block 27 and that the sliding block or the rotating socket 28 has an upwardly open T-slot 29 and into the T-slot 29 a bearing part 30 attached to the end of the threaded shaft 23 is used.
  • the hammer head-like connection formed by the T-groove 29 and the bearing part 30, of the threaded shaft 23 of the longitudinal adjustment 12 with the cover plate 18 or the holding flange 15 of the holding device 13, as realized in the exemplary embodiment which can be seen particularly clearly in FIG. 4, allows after loosening the retaining screws 19, the cover plate 18 or the holding flange 15 can easily be removed upwards, the bearing part 30 then sliding out of the T-groove 29. All other parts then remain on the tool saddle 6, which can be easily removed from the base frame 4 after loosening the transverse adjustments 11.
