Definitions

  • the invention relates to a panel saw with an upright frame according to the preamble of claim 1.
  • the object of the present invention is therefore to provide a panel saw in which damage to the support members is reliably avoided in the case of vertical cuts.
  • a first locking element which can be actuated together with the latching device is provided and which, in a locking position, engages in the displacement path of the circular saw perpendicularly to the contact surface.
  • the locking member is further actuated by a switching member arranged on the guide bar together with the latching device, this results in a particularly simple arrangement with convenient operation via a shift lever.
  • This can be moved into a rest position in which the latching device is in the release position and the locking member is in the locking position.
  • the guide bar is locked to the frame via the latching device, while the locking member is in the release position.
  • the circular saw can thus be submerged by hand or by a power drive.
  • the invention can find a particularly advantageous application in panel saws with a pivotable saw blade for executing vertical and horizontal saw cuts.
  • a clamping device is provided, with which the slide can be clamped to the guide beam in order to carry out horizontal saw cuts.
  • This clamping device is also expediently actuated with the switching lever already present, which can be moved from the zero position into a clamping position. In this clamping position, the locking device is in the release position and the locking member is in the locking position.
  • the locking lever according to DE-A-27 13 520, which interacts with the clamping device. This locking lever means that with a horizontal saw cut, immersion is only possible after the clamping device has been actuated.
  • an alternative grate can be operated in a known manner so that the support members are not damaged in horizontal saw cuts.
  • the present invention together with known locking devices, thus offers universal protection against damage to the support members and a substantial relief for the operator.
  • FIG. 1 and 2 show a frame 1 which is slightly inclined against the vertical and on which the horizontal support members 2 of an alternative grate are mounted so as to be vertically displaceable.
  • a guide beam 5 is mounted horizontally. He carries a carriage 6, which can be moved along the guide beam 5 in the height direction.
  • a circular saw 8 is mounted on a guide rod 7, the saw blade 9 of which can be driven by an electric motor 10 via a belt drive 11.
  • a guide tab 12 is connected to the slide 6 and is provided with a guide groove 13.
  • Circular saw 8 is immersed in FIG. 3 Position shown, in which both the guide bar 5 and the carriage 6 can be moved freely. To carry out a vertical saw cut, the circular saw 8 is moved in the direction of the support members 2, which together form a support surface 14 for a plate-shaped workpiece (not shown) (FIG. 4).
  • the circular saw 8 can be immersed either by hand or by means of a power drive.
  • a latching device 16 is arranged on the guide bar 5, which has an upper latching bracket 17 and a lower latching bracket 18. Locking bracket 17 and locking bracket 18 are connected to each other by a locking rod 19.
  • Locking bracket 17 is guided in a bore 20 in the superstructure 21 on guide beams 5 so as to be displaceable in the vertical direction and, in the locking position, engages around locking pins 22 which are fastened in the upper cross member 3,
  • the lower locking bracket 18 cooperates in a similar manner with locking pins 23 which are fastened in the lower cross member 4.
  • Locking rod 19 is mounted in a switching tube 24 which penetrates the carriage 6 and can be rotated relative to the latter by a switching lever 25.
  • a lifting plate 26 arranged at the upper end of the switching tube 24 is provided with inclined tabs 27 which act on a roller 28 of the locking bracket 17.
  • the switching tube 24 has a square cross section and is encompassed by a switching sleeve 29 which is rotatably mounted in the carriage 6.
  • a switching sleeve 29 which is rotatably mounted in the carriage 6.
  • a locking member 31 is furthermore mounted horizontally displaceably against the action of a compression spring 32.
  • a shift finger 33 which is fastened to a tab 34 on the shift sleeve 29, engages in a groove 35 of the locking member 31 in the positions shown in FIGS. 3 and 4.
  • an opening 36 is provided, which in the position of the blocking member 31 shown in FIG. 3 is covered by this inward.
  • a second locking member 37 in the form of a finger plate is connected to the circular saw 8 and enters the opening 36 when the circular saw 8 is immersed.
  • the first locking member 31 prevents the circular saw 8 from moving further in the direction of the support surface 14.
  • the guide bar 5 To make vertical saw cuts, the guide bar 5 must first be moved so that the locking brackets 17 and 18 are aligned with the corresponding locking pins 22 and 23. If the shift lever 25 is now pivoted into the latching position shown in FIG. 4, the shift sleeve 29 takes the shift tube 24 with it and the lifting plate 26 moves the upper latching bracket 17 downward until it engages around the latching pin 22. At the same time locking rod 19 pivots the lower locking bracket 18 also in the locking position.
  • the switching sleeve 29 acts on a clamping device 38 such that the slide 6 is clamped on the guide bar 5 when the switching lever 25 is pivoted into the clamping position shown in broken lines in FIG. 3.
  • the shift finger 33 is lifted out of the groove 35 by the first locking member 31, so locking member 31 thus covers opening 36 toward the inside.
  • the clamping device 38 is only actuated when horizontal saw cuts are to be carried out.
  • the circular saw 8 is pivoted into the position shown in dot-dash lines in FIG. 1, the second locking member 37 being aligned with the guide groove 13 and serving for the precise guidance of this circular saw when the circular saw 8 is immersed.
  • a locking lever 39 must be pivoted in a known manner with the shift lever 25 into the release position shown in broken lines in FIG. 1.
  • the switching sleeve 29 can also serve in a known manner to move the support members 2 out of the path of the saw blade 9 in a horizontal saw cut via a coupling element (not shown).
  • the operator is therefore in a position with a single shift lever 25 to lock the guide bar in the case of vertical saw cuts and to remove the lock for the immersion movement of the circular saw 8 and at. horizontal saw cuts in a further clamping position to clamp the carriage 6 on the guide beam 5 and, if given, lift the support members 2 out of the path of the saw blade 9.
  • This one-hand operation via a single switch lever relieves the operator and allows faster and more convenient handling of the panel saw.
