Definitions

  • the invention relates to a protective hood for a circular saw a housing that covers the saw blade and is open at the bottom.
  • the invention has for its object a protective hood for To provide circular saws in which the to be cut Workpiece is automatically drawn in and without manual intervention Saws is pulled through.
  • this object is achieved in that in the housing a feed device for the sawn Workpiece is attached.
  • This feed device consists of advantageous development of the invention from two to two Sides of the saw blade arranged feed elements, for example driven drive belt.
  • the main advantage is achieved that the Feed device both pulls in and to saw the workpiece also moved forward over the entire cutting process and even after the end of the cutting process on the circular saw table holds so that it cannot fall off. This will Avoid getting your hands in the danger area of the saw blade can reach.
  • the distance of the Feed elements can be set so that not only the width the feed device is adapted to the width of the workpiece, but also the space between the two feed elements can be enlarged, which is then required If the saw blade has to be tilted, it will make oblique cuts perform.
  • the housing is over a joint parallelogram hung on a rigid holder.
  • the table 10 is a conventional circular saw shown, the slot 12 (see FIG. 4) for the Passage of a saw blade 14 has.
  • the feed direction (cf. An arrow in FIG. 4) is behind the saw blade 14 lowerable scoring blade cover 16.
  • a gallows 18 is attached to the side of the table 10, on the latter horizontal cantilever 20 the protective hood 22 according to the invention is hung.
  • This consists of an approximately cuboid, downwardly open housing 24 that over two Joint parallelograms 26 on the cantilever 20 adjustable in height is hung.
  • a driving belt 34 which can be designed as a toothed belt and made of elastic Material exists.
  • the rear axis 30 in the feed direction is via a belt or Chain drive 36 with the motor shaft 38 of a drive motor 40 connected, which is attached to the rear of the housing 24 is.
  • the position of the two rollers 32 one of the two Driving belt 34 is fixed, while the rollers 32 of the second Driving belt 34 'on their axes 28 and 30 adjustable are so that the distance between the two drive belts 34 and 34 ' can be adjusted.
  • connection piece on the top of the housing 24 44 provided to which a suction device for suctioning Chips and dust can be connected.
  • an operating handle 46 attached, via which the housing 24 by hand on the workpiece can be lowered.
  • the protective cover 22 For sawing a workpiece, such as a long board, the protective cover 22 is first lowered, after which the saw blade 14 is turned on. About a not shown The drive motor 40 then becomes an adjustable timer switched on for the two drive belts 34, so that on the workpiece 10 lying in the table automatically into the saw is drawn in and the cut is made. Alternatively it is possible to provide a proximity switch on the housing 24, the only turns on the saw blade 14 when the housing 24 is open rests on the workpiece.
  • Figures 5 and 6 show that by moving the Driving belt 34 'with its two rollers 32 on the respective axes 28, 30 the distance between the two belts can be adjusted so that an inclined saw blade 14 for making diagonal cuts between the drive belts 34 can intervene and thus optimally through the housing 24 is covered.
