Definitions

  • the invention relates to a method for introducing surface channels with an at least approximately rectangular cross section in sheet material made of soft material, in particular mineral fiber insulation mats or sheets made of a styrene polymer, in which a motorized cutting tool with an oscillating cutting knife is used.
  • the invention further relates to a device for introducing surface channels with an at least approximately rectangular cross section in sheet material made of soft material, in particular mineral fiber insulation mats or sheets made of a styrene polymer, with a motor-driven cutting tool, in which a cutting knife about an axis with an angular amplitude in Range between about 0.5 ° and 7 ° and a frequency in the range of about 10,000 to 25,000 min ⁇ 1 is oscillating and the cutting knife has angled sections that are at least partially provided with a cutting edge.
  • the invention relates to a use of the above-mentioned device.
  • a cutting tool of the type already explained is also known, in which an oscillating cutting knife is also used.
  • the cutting knife has a 90 ° bent blade, the two legs of which are each provided with a cutting edge.
  • This known cutting knife is provided for the sole purpose of cutting through elastic adhesive beads on vehicle windows.
  • This special tool is neither intended nor suitable for other areas of application. In particular, this tool is unsuitable for introducing surface channels into soft material plate material because the outer leg of the blade extends parallel to the lower surface of the power tool and the oscillating shaft forms an acute angle with the cutting edges, so that cutting into surfaces of plate material is impossible is.
  • the invention is based on the object of developing a method and a device of the type mentioned at the outset, or of specifying a use with which it is possible to introduce surface channels into plate material made of soft material in a short time and in a simple and reproducible manner.
  • this object is achieved on the one hand in that a U-shaped cutting knife, the cutting edge of which rotates around the sections forming the U, is guided in a straight line through the plate material.
  • this object is achieved in that, in a first step, an L-shaped cutting knife, the cutting edge of which rotates around the sections forming the L, is guided essentially in a straight line through the plate material, and in a second step Cutting knife with a straight section is guided parallel to the guidance of the first step through the plate material such that a continuous strip of plate material can be removed from the plate material.
  • the first and second steps are preferably carried out several times in succession, in parallel and next to one another.
  • the object on which the invention is based is achieved, on the one hand, by the cutting edge rotating over at least three sections which form a U with one another.
  • the object on which the invention is based is achieved in that the cutting edge rotates over at least two sections which form an L with one another.
  • the object on which the invention is based is still achieved by the use of a device of the type mentioned at the outset for introducing surface channels with an at least approximately rectangular cross section in sheet material made of soft material, in particular mineral fiber insulating mats.
  • the U-shaped knife of the one embodiment according to the invention with a total of at least three cutting edges namely causes a complete surface channel to be cut out in a single operation, the cutting line leading from surface to surface.
  • the L-shaped knife of the other embodiment according to the invention with a total of two cutting edges causes two sides of the surface channel to be cut out in a first operation, while the third side is subsequently cut out in a second operation.
  • This has the advantage that surface channels of any width can be produced by performing the two work steps as often as desired next to one another and in parallel.
  • the L-shaped knife is then used to cut out a further strip of material on the underside on one side of the channel which has already been cut out, which strip is cut in the longitudinal direction in a further second operation and can be removed or dropped out.
  • the cut-out material residue can only be removed from the cut channel, but does not need to be separated out, so that in practice no operation is required at all, because the cut-out material migrates out of the cut-out channel by itself or with an inclined work surface falls out.
  • At least one of the sections forming the free ends of the U is followed by a further section which is angled by approximately 90 °.
  • this measure has the advantage that the further section can serve as a support on the surface of the plate material, so that when the surface channel is cut, the knife cannot sink into the plate material in an uncontrolled manner becomes.
  • the angled section is provided at the outer, free end of the section forming the U, extends towards the clamping side and is supported on one of the sections on the clamping side. Since the outer part of the cutting edge is thus additionally supported, the mechanical stability of the cutting edge is considerably improved in this way.
  • the support can be achieved in a simple manner in that the angled section is welded to one of the sections on the clamping side, which can be achieved, for example, by spot welding.
  • the cutting knife comprises a blade holder for inserting an exchangeable blade.
  • This measure has the advantage that with one and the same blade holder, surface channels of different widths, depths or other contours can be cut in close succession, with only minimal changeover times being required.
  • the blade is U-shaped and can be locked with its free ends in slots in the blade holder.
  • a non-angled cutting knife can be inserted into the cutting tool.
  • This measure has the advantage that the strips of material that have already been loosened on one or both sides on the second or third side can be cut out with a straight, non-angled cutting knife.
  • the cutting edge is not straight at its cutting edge, but rather is serrated or wavy.
  • the cutting knife is provided with a smooth cutting edge on one side in a cutting direction and with a serrated or wavy cutting edge on the other side in the opposite cutting direction.
  • This measure has the advantage that one and the same tool can be used for two different materials. If the tool with the clamped cutting knife is to be used in a fibrous material, it only needs to be guided through the material with the smooth cutting edge in one cutting direction, while with another, rather coarse material, the tool in the opposite cutting direction with the serrated or wavy edge is passed through the material.
  • This is a great advantage, particularly when it comes to interior fittings, if, on the one hand, mineral fiber mats and, on the other hand, styrene polymer sheets are used, one after the other, in succession, both of which are known to be used for thermal insulation. The craftsman then does not need to change the cutting knife, but rather can process both materials with an unchanged tool, only the tool having to be guided through the material once in one direction and the other in the other direction.
  • the cutting edge runs in an arc shape, preferably along a convex arc. This measure also has the advantage that a better cut is produced in numerous applications, be it with straight or serrated or wavy cutting edges along the arc shape.
  • This embodiment of the knives also has advantages in terms of cut quality in numerous applications.
  • exemplary embodiments of the invention are preferred in which the axis is perpendicular to a first one Clamping section of the cutting knife adjacent and provided with the cutting edge extends.
  • This known measure has the advantage that the motor-driven cutting tool can be guided with its longitudinal axis perpendicular to the surface of the material, which is ergonomically advantageous in numerous applications and ensures good access to the material.
  • Fig. 1 denotes an electric tool with a housing 11, which is only indicated schematically and broken off.
  • a front drive flange 12 is connected to the housing 11, which preferably contains an electric drive motor, which flange e.g. can contain an angular gear.
  • the drive flange 12 is also provided with a protective bracket 13.
  • An axis 14 extends at right angles to the longitudinal axis of the housing 11 and is at the same time the axis of a drive spindle 15 in the drive flange 12.
  • a double arrow 16 indicates that the drive spindle 15 moves in an oscillating manner, ie rotates back and forth by a small angular amount.

  • a cutting knife 20 is inserted into the drive spindle 15, the further details of which are shown in FIGS. 2 and 3.
  • the cutting knife 20 comprises a first, flat section 21, which is followed by a second, inclined section 22. This is followed by a third, flat section 23, from which a fourth section 24 extends vertically downward.
  • the fourth section 24 merges via a fifth section 25 bent by 180 ° into a sixth section 26 running vertically upwards.

  • FIGS. 4 and 5 show a slightly modified exemplary embodiment of a cutting knife 20a, in which the first to third sections 21a to 23a are combined to form a common inclined section which runs at an angle 35 of, for example, 15 ° with respect to a horizontal plane.
  • the cutting knife 20a also has a U-shaped shape, but does not have a flat section at the left free end of the U in the illustration in FIGS. 4 and 5, as is present in the embodiment of FIGS. 2 and 3 with 27 .

  • the arrangement is preferably such that the vertical sections 61, 63 of the blade 60 are moved slightly towards one another with the fingers of the user, that is to say are pressed together, as indicated by a double arrow 75 in FIG. 6. In this position, the free ends of the vertical sections 61, 63 can be guided past the tongues 51, 53 of the slots 45, 46 until a desired depth of cut T is achieved by inserting said free ends into the slots 45, 46.

  • the mat 80 is provided on a flat surface with an aluminum liner 81, as is usually used as a vapor barrier in such insulation mats becomes.
  • FIG. 7 shows, as an example, the case in which a cutting knife 20 is used, as has already been shown and explained in FIGS. 1 to 3.
  • the cutting knife 20 is connected to the drive spindle 15 of the power tool 10 and the drive is then switched on.
  • the cutting knife 20 then oscillates with the values mentioned at the beginning.
  • the cutting knife 20 can now either be brought laterally to the mat 80 to insert a channel 82 or can be dipped at any location into the surface 84 of the mat 80 in order to cut out a surface channel 82 from the material of the mat 80.
  • the cutting knife 20 is guided so that the third and seventh, each flat section 23 and 27 of the cutting knife 20 is guided along the surface 84 of the mat 80 so that it serves as a vertical stop and an undefined sinking of the cutting knife 20 into the mat 80 is prevented.
  • the oscillating cutting knife 20 is now guided in a straight line along the surface 84, as indicated by an arrow 83 in FIG. 7.
  • straight means that a predetermined course of the channel to be formed is followed, which of course can also be curved at least in places.
  • the term "rectilinear” is therefore only intended to illustrate that the channel 82 to be formed is an elongated structure.
  • 90 denotes another embodiment of a cutting knife.

  • the serrated design of the cutting edge 95 is particularly advantageous for coarsely structured materials, e.g. Styrene polymers as are generally known under the registered trademark "STYROPOR".
  • Such materials consist of material balls with a diameter of 1 or more mm. If such materials are cut with straight or already blunted knives, the material balls are not cut but rather jump out of the material elastically when cutting. This leads to unclean cut edges and contamination in the area around the work place. It has now been found that such materials can advantageously be cut with serrated or corrugated cutting edges, in particular when the distance between the serrations or waves is at least as large as the diameter of the beads.
  • FIG. 9 Another variant of a cutting knife 90 ', as shown in FIG. 9, is finally provided with a straight cutting edge 95b. 9 corresponds completely to the cutting knife 90 of FIG. 8. Accordingly, the side view of FIG. 10 rotated by 90 ° is the same in all cases.
  • FIG. 9 it is also indicated with 95b 'that the cutting knife 90' can be provided with different cutting edges on the right and left side in FIG. 9. While the right side in FIG. 9 is provided with a straight but serrated cutting edge 95b, the left side in FIG. 9 is also provided with a straight but smooth cutting edge 95b '. This is to indicate that the cutting knives, regardless of their other shape in the two possible cutting directions right / left can be provided with different cutting edges 95b and 95b ', so that one and the same cutting knife 90' can be used for cutting two different materials can and only the cutting direction, ie the direction in which the tool is guided must be changed.
  • 96 denotes an axis about which the cutting blades 90 and 90 'execute the oscillating movement.
  • the oscillating drive axis 14 is at an angle of 90 ° to the longitudinal axis of the housing 11. Therefore, if one of the cutting knives 90, 90 'shown in Figs. 8-10 is used with this cutting tool 10, the cutting edges 95 and 95b are aligned with the longitudinal sections 92 and 94 in extension of the longitudinal axis of the cutting tool 10 while they are being cut in the previously described embodiments with the longitudinal axis of the cutting tool 10 included an angle of 90 °.
