Definitions

  • the invention relates to a closing frame for a machine such as a punching crucible, a flat-bed punch, a printing press, with a frame profile running in a rectangle made of two horizontal and two vertical profiles, with two horizontal cross bars being guided laterally to fix the part to be fixed, in particular the cutting plate (steel cutting) and move up and down.
  • Stamping crucibles are known through which cardboard boxes are stamped and embossed.
  • the cardboard is placed on a swing arm, which presses it against a cutting plate (steel strip).
  • This insert has to be fixed in the middle of the frame using intermediate parts. Inserting these intermediate parts and clamping the insert with locking tools is a considerable workload, especially since the frame has to be removed from the machine. Large-format locking frames are so heavy that they can only be removed from the machine with the help of a crane.
  • the object of the invention is to improve a closing frame of the type mentioned in such a way that the part to be fixed can be quickly and easily attached without having to remove the closing frame from the machine, the outside dimensions of the closing frame remaining so small that it continues to be in the machine can be used without projecting.
  • Such a locking frame can always remain in the machine and is actuated there by hand in such a way that the cross bars are moved up and down by rotating the drive shaft and thus by rotating the two vertical spindles, the part to be fixed always being moved by moving the two cross bars together centered and clamped in the center of the horizontal axis.
  • the part to be fixed only needs to be placed on the lower crossbar and by rotating the drive shaft, in particular via a side crank, the part to be fixed is securely fastened in the center.
  • crank is releasably attached to one end of the drive shaft.
  • the part to be fixed is clamped with precisely metered translation force. There is no need for a lock because the fine threads of the spindles to the threaded holes of the struts act like quadruple screw connections with appropriate self-locking.
  • the safety devices are not impaired by the very flat, space-saving design. Each part to be determined is always automatically centered in the center. Bars and locking tools are completely eliminated. This means that they cannot fall out and cause damage during the punching process.
  • the underside of the upper crossbar is inclined in such a way that the front edge of the underside is lower than the rear edge.
  • the top of the lower crossbar should also be inclined in such a way that the front edge of the top is higher than the rear edge.
  • the upper cross bar has a label in the middle, in particular a vertical notch for center recognition, which corresponds to a label of the part to be determined.
  • the part to be fixed is always automatically clamped in the center of the horizontal axis. This is important because the swing arm has a central axis, at the ends of which the two pull arms pull. Due to the central arrangement of the part to be fixed, work can be carried out over the entire surface, in particular punching. It prevents that only one edge of the tool, especially the Cutting knife will strike.
  • the closing frame 1 has a frame profile which runs in a rectangle and consists of two horizontal bars 2a, 2b and two vertical bars 3a, 3b made of steel bars.
  • a spindle 4a, 4b is mounted vertically and thus parallel, which is as close as possible to the adjacent vertical profile.
  • the spindles 4a, 4b are passed through the upper horizontal profile 2a and protrude above this profile 2a.
  • the upper ends have small bevel gears 5a, 5b, the axes of which are vertical.
  • a further two bevel gears 6a, 6b engage in these bevel gears, which are fastened on a horizontal drive shaft 7 which lies above the profile 2a parallel to the latter and can be driven by a removable hand crank which is plugged onto the shaft 7 at the side of the closing frame.
  • the shaft 7 is rotatably supported in three bearing blocks 9a, 9b, 9c, which are attached to the top of the profile 2a.
  • the diameter of the four bevel gears 5a, 6a, 5b, 6b is not or only slightly larger than the width of the frame profiles 3a, 3b, 2a, 2b, or as the depth of the closing frame.
  • each spindle has a thread that is opposite to the thread of the lower half.
  • each upper half can have a left-hand thread and each lower half can have a right-hand thread.
  • the underside 10b of the crossbar 10 is not horizontal, but rises from the front edge to the rear edge and the top 11b of the crossbar 11 drops towards the rear, so that both crossbars 10, 11 form bevels through which one is placed between the crossbars part to be fixed, in particular a cutting plate (steel cutting) is held securely and pressed backwards against the dressing plate or the anvil plate.
  • a cutting plate steel cutting
  • the underside 10b of the upper crossbar 10 is largely flat at right angles to the vertical surfaces.
  • the front edge of the underside is lower and flees upwards at an acute angle until the flat surface is reached.
  • the lower cross bar is shaped the other way round.
