Definitions

  • the invention relates to a cutting saw for sawing preferably rectangular cutouts from usually plate materials.
  • cutouts are often required in various areas of woodworking and other trades such as hall construction.
  • Door cut-outs, sink cut-outs, cut-outs for various uses such as screens are some examples of their recurrent need.
  • cutouts are made directly on site by means of dip saws, a type of circular saws.
  • the disadvantage of this type of production is that the size of the cutout must first be torn open on the workpiece. Then, a guide rail is mounted on the workpiece to move the saw along it to achieve a straight cut. For a rectangular cut-out, it is necessary to fasten the guide rail at least four times, whereby the maintenance of the perpendicularity to the previous cut can only be accomplished with difficulty with the new fastening.
  • a milling template which has a windmühlen- wing-like arrangement of the guide rails, whereby a stepless and rapid adjustment is ensured.
  • the router After setting to the desired size of the cutout on the guide rails, the router is guided along the inner edge of the milling template by a copying sleeve arranged concentrically around the milling tool, thus creating the cutout. Mobility and individual size adjustment are in this way the cutting position certainly given, however, the problem remains the relatively large Materialzerspanung Cutting and the rounded corner area of the cut due to the use of milling tools.
  • the duration of a milling process by means of routers is considerably longer than that of a sawing process.
  • the present invention is therefore based on the object to provide a rational way to produce cutouts, are avoided in the disadvantages that occur both as a result and during production, while exploiting the advantages of known manufacturing methods.
  • the cut-out saw then has a saw housing housing a rotating drive unit connected to a gearbox, wherein by means of the gearbox the rotation of the drive unit is translated into a linear motion or oscillating movement of a replaceable saw blade secured to the gearbox by a tensioning device.
  • the type of such saw blade movement is the same as that of commercial jigsaws.
  • the aforesaid sawing housing housing the drive unit with gearbox and attached saw blade is itself pivotable and height-displaceable on a pivoting and lifting device, such that the saw blade, which is not in engagement with the workpiece at the beginning of a sawing operation, faces the workpiece surface pointing teeth from a directed for example parallel to the workpiece surface saw blade movement in a direction perpendicular to the workpiece surface and thereby simultaneously be engaged with this engaged blade movement can be brought.
  • the choice of a certain plunge angle of the saw blade over latching steps has the advantage that an optimum angle is achieved. If this is too large, the saw blade performs a pure impact movement in the direction of the workpiece surface. A penetration of the saw blade is impossible. The workpiece, saw blade and the entire saw are thus damaged. If the angle is too small, a penetration of the workpiece is also not possible. If the workpiece is penetrated by the saw blade, the depth of the penetration can be fixed by a locking device, which is important for different workpiece thicknesses and ensures good utilization of the entire sawtooth area.
  • An additional advantage of the locking steps and the simultaneous possibility of depth adjustment is that the saw blade can be immersed only slightly at a certain angle in the surface of the workpiece, which has a Vorrit- zen the material result, thereby tearing the upper during subsequent sawing Cutting edges of the cut is avoided.
  • Another device on the pivoting and lifting device is found with a limitation for the angle of the saw blade leading edge to the workpiece surface over a predetermined amount. If sharp-edged cut-outs perpendicular to the workpiece surface are to be created in the corner area, said angle must not exceed 90 °.
  • the invention also provides a guide carriage before.
  • This guide carriage is on the one hand on a guide rail, such as a guide rail of the milling template DE 196 40 031 C1, play-free longitudinally displaceable and fixed to this at any position and on the other hand firmly connected to the swivel and lifting device.
  • a guide rail such as a guide rail of the milling template DE 196 40 031 C1
  • the cutting saw for straight cuts in combination with known milling template.
  • an attachment possibility on both sides of the the pivoting and lifting device provided.
  • cut-outs can be created clockwise and counterclockwise.
  • the saw blade of the cutting saw differs from that of a conventional jigsaw.
  • the main body then has about 2-3 times the thickness and a 3-4 times the width of the ordinary jigsaw blades. This serves to prevent bending of the sheet, among others. prevents immersion and better guidance in straight cuts is achieved.
  • Another peculiarity is that the saw blade not only has teeth in the thrust direction when viewed after penetrating the workpiece during the cutting operation, but also in parallel in the opposite direction, i. in the pulling direction. This offers the possibility of the saw, after placing the guide carriage on a guide rail in both directions along this guide rail to a certain point, which is determined on the one hand by the respective transverse guide rails and on the other hand by adjusting screws on the pivoting and lifting device to move.
  • the saw blade is also tapered towards its free end in such a way that when it is immersed in the workpiece, the force that counteracts the movement of the saw blade, as low as possible.
  • the known milling template is set to the desired dimension and fastened to the workpiece.
  • the cutting saw is placed on a guide rail and fixed, then pressed the saw with an engaged angle of saw blade to workpiece surface in the direction of the workpiece until the saw blade engages the workpiece and penetrates it. Then the cutting angle is changed until it reaches about 90 ° to the workpiece surface.
  • the saw can be pushed forwards and pulled back until each of the adjusting screws touches the respective transverse guide rails and limits the saw cut. This is repeated four times for a quadrangular cutout, the result being exact corner and sharp-edged cutouts.
  • the sawing of cutouts with the cutting saw without the aid of guide rails is possible.
  • a lever to be operated located at the bottom of the pan and lifting device, for example, a lever to be operated, extendable anti-slip feet that protrude after actuation of a lever from the bottom of the pan and lift and prevent slipping of the saw on the workpiece.
  • a subsequent movement of the saw to create the cut-out after lifting the anti-slip feet in the original position is possible again.
