Definitions

  • the invention relates to a processing machine, in particular circular saw, such.
  • a processing machine in particular circular saw, such.
  • B. a sliding table saw with a pivotally trained by means of a pivoting machining tool and a protective cover for the machining tool according to the preamble of claim 1.
  • One such machines is from the DE 103 48 587 B3 known.
  • Such processing machines in particular circular saws are known as sliding table saws.
  • Such sliding table saws must for woodworking due to the accident prevention Vorachriften the saw blade, which exits above the workpiece, completely cover against contact.
  • the protective cover is on a frame on the machine body attached.
  • the protective cover is adjustable in height so that it can be adjusted to the respective workpiece height or the height from which the saw blade protrudes from the workpiece.
  • it is customary to use a narrow protective hood in order not to cause unnecessary obstruction in the workpiece guide behind the saw blade, also in connection with the guide rule.
  • most sliding table saws, including machine tools are today designed as swiveling machines, at least in a range of 0 ° to 45 °.
  • a processing device for splitting plate-shaped workpieces having a first support table for the workpieces and on the machine frame linear guide assemblies are provided to move the machining tool on a carriage in the cutting direction.
  • the known processing device has a pressure bar to push the workpiece onto the support surface of the support table.
  • the pressure bar is to be arranged above the cutting line and has a slot on the side facing the saw blade.
  • the slot is only slightly wider than the thickness of the saw blade.
  • Side next to the slot for the slot line bearing surfaces are provided in the pressure bar, which are also necessary to press the workpiece against the machine table. A pivoting movement of the saw blade with attached pressure bar inevitably leads to the collision of the saw blade with one of these bearing surfaces.
  • the object of the invention is achieved by a processing machine, in particular circular saw according to claim 1.
  • a processing machine in particular circular saw according to claim 1.
  • the guard according to the invention is coupled to the pivoting device of the machining tool, so that it generally follows the same angle at each adjustment of this adjustment. This is a constant protection of the exiting saw blade, as prescribed, guaranteed. Damage to the protective cover, as often occurring in the prior art, is completely avoided.
  • advantages are achieved by the inventive solution to the extent that retooling, can also be completely avoided from a narrow to a wider protective hood at a diagonal cut. This will of course make the entire machine more efficient.
  • the solution according to the invention offers the following advantages.
  • a variant with a longitudinally movable arrangement of the saw blade is also possible according to the invention.
  • the solution according to the invention can also be used very well in a variant of a processing machine with a fixed, rotating processing tool (eg a saw blade), in which, for example, the workpiece is moved through the processing machine or by hand.
  • the design of the protective hood according to the invention is adapted in the Weseitlichen to the diameter of the saw blade and at least formed in its width such that a pivoting movement in one direction to a maximum of 45 ° or 46 ° deviating from the vertical in one direction is possible.
  • the holding function as is necessary in the prior art, is also not necessary according to the invention. Due to the fact that the protective hood is coupled to the pivoting device of the machining tool in order to linearize the movement of the machining tool to follow, it is possible that in case of insufficient space in the protective hood, this is moved laterally linear, to then again to provide sufficient space for the saw blade.
  • the protective hood due to the coupling with the pivoting device, follows the movement of the machining tool with a linear movement, at least in one direction.
  • This is preferred, for example, if the guard has a certain width and the guard of the pivoting movement of the tool should not follow permanently.
  • the guard can perform a linear movement perpendicular to the cutting line of the machining tool to position the guard respectively in a left or right of the machining tool or its cutting line.
  • the protective hood is essentially adapted to the diameter of the machining tool.
  • a certain amount of leeway is given, so you do not have to change the guard when changing tools. But it makes sense not to choose the deviation too large in order to provide adequate protection, with little space and in particular for optimum suction.
  • Another aspect of the invention is characterized in that the machining tool with its circle in the pivoted position does not intersect the side wall of the guard at least in one of the end positions.
  • This has already been described above and refers to a solution in which a linear movement of the protective hood follows either in a position to the left of the cutting line of the machining tool or to the right of the cutting line. It is possible that the protective hood for this movement is directly or indirectly connected to the pivoting device of the machining tool.
  • the coupling can also be done so that a linear movement, for example, only takes place when there is a risk that the machining tool with its circle could possibly damage the protective cover. This is always the case when the circle of the machining tool with the side wall and / or rear wall of the guard in collision could.
  • a processing machine is also characterized according to a variant in that a conveying device is provided for the transport of the workpiece and / or the workpiece is manually movable.

It is also advantageous if the guard in the vertical direction or at right angles to a machine table or the support plane for the workpiece is adjustable. Thus, the altitude of the guard of the thickness of the workpiece can be adjusted. This is also a certain adjustability given, for example, when a larger blade is used.
  • the protective hood is U-shaped and has the opening of the U to the machine table or to the support plane. It is also advantageous if the guard is adjustable in a first end position and in a second end position. The end positions are to be understood as each maximum external position with respect to the cutting line seen left or right next to the saw blade in the cutting direction.
  • the guard has such a width that allows a pivoting movement of the machining tool at an angle of ⁇ 45 ° without a linear movement of the guard at least in one direction.
  • the machining tool is pivoted to the right as seen from the vertical, the protective hood can remain in the right-hand end position without causing a collision the side wall of the protective hood comes with the circle of the saw blade. If the saw blade is then pivoted in the other direction - 45 °, a linear movement of the guard is necessary to prevent a collision of the circle of the saw blade with the guard. In the left end position, however, an adjustment from 0 ° to -45 ° without an additional linear movement of the guard is possible.
  • the invention is characterized according to a further variant in that a suction nozzle for connecting a suction device is provided on the protective hood, which is preferably arranged on the closed side of the U or on the side facing away from the machine table.
