Definitions
- the invention relates to a cutting knife for a cutting tool for severing adhesive beads on vehicle window panes, with a fastening part and a cutting part, the fastening part having a first end of a receiving opening for fastening to an oscillation drive for oscillating drive of the cutting knife about an axis perpendicular to the receiving opening and tapering toward a second end, and wherein the cutting member and the fastening member extend at an angle to each other.
- Cutting blades used in conjunction with an oscillation drive to remove window panes from vehicles are known.
- a cutting knife with a U-shaped cross section is known, with a fastening part for fastening to an oscillation drive for oscillating drive of the cutting knife about an axis perpendicular to the fastening opening, and with a crescent-shaped cutting part which is connected to the Fastening part is connected via a central web.
- the cutting knife When the cutting knife is driven by means of the oscillation drive, it is set into rotary oscillations at a high frequency, so that the adhesive bead can be severed with a kind of sensory effect.
- the cutting knife is inserted from the outside through the gap between the window pane and the body flange, the adhesive bead is pierced or the cutting knife is passed through a recess in the adhesive bead and then gradually cut the adhesive bead after switching on the oscillation drive.
- a cutting knife with an L-shaped cross section is known from US Pat. No. 4,199,852.
- this cutting knife is not set in rotary oscillations by a rotary oscillation drive, but in a striking movement by a longitudinal oscillation drive, with which the cutting part protruding at an angle from the fastening part sets into an oscillating movement perpendicular to the latter becomes.
- a guide roller is provided for support against a window pane.
- the invention is therefore based on the object of providing an improved cutting knife for severing adhesive beads on the window panes of vehicles, with which window panes can be separated from outside the vehicle even under spatially unfavorable conditions, with the greatest possible fatigue-free working and high stability of the cutting knife should be and the risk of damage to the window and the vehicle paint is reduced.
- a cutting knife for a cutting tool for cutting adhesive beads on vehicle window panes with a fastening part and a cutting part, the fastening part at a first end having a receiving opening for fastening to an oscillation drive for oscillating driving of the cutting knife by a perpendicular to the receiving opening Has axis and tapers towards a second end, wherein the cutting part is made together with the fastening part from a flat blank and angled from the second end of the fastening part this extends, wherein the cutting part has two side edges which converge at the outer end of the cutting part, and wherein at least one side edge of the cutting part is designed as a cutting edge which is provided with a serrated or sawtooth cut.
- the cutting knife according to the invention enables window panes to be removed from outside a vehicle even under geometrically relatively unfavorable conditions. Because the cutting part is set in rotary oscillations by means of the oscillation drive, with which the cutting part moves back and forth in a direction perpendicular to its cutting edge in the cutting direction, the drive power of the oscillation drive itself is used to cut through the adhesive bead.
- the shaft or sawtooth grinding on the at least one cutting edge improves the penetration of the cutting edge into the adhesive bead and thus achieves a higher cutting performance with less effort. At the same time, the risk of breakage is reduced.
- the second side edge of the cutting part is designed as a straight cutting edge.
- the additional cutting edge on the side of the cutting part opposite the wave or sawtooth cutting edge supports the cutting action during the backward stroke of the cutting part and at the same time enables the cutting part to be moved back against the cutting direction by an already cut adhesive bead, for example in order to take a new approach to the cutting process to enable.
- the cutting part is ground on both sides on both sides, so that a spherical cross section results.
- the fastening part is ground on at least one side edge in the transition region to the cutting part, this preferably taking place on both sides, and hollow fillet-like depressions running out toward the side edges being formed.
- Such a configuration results in a particularly favorable cutting effect, in particular in the transition region between the cutting part and the fastening part, as a result of which the risk of breakage of the cutting knife is significantly reduced and the cutting process can be carried out with less force overall.
- the double-sided grinding of the cutting part in the transition area, with the formation of concave depressions between the cutting part and the just formed remaining part of the fastening part additionally results in improved guidance of the cutting knife during the cutting process.
- both cutting edges of the cutting part converge at the end to form a rounded tip. This facilitates the insertion process into the adhesive bead at the start of the removal process.
- fastening part and the cutting part preferably extend approximately at right angles to one another.
- Figure 1 is a sectional view of a cutting knife according to the invention in use with an oscillation drive.
- FIG. 2 shows a top view of the cutting knife according to FIG. 1;
- Fig. 3 is a side view of the cutting knife of FIG. 2 and
- Fig. 4 is a partial perspective view of the cutting knife seen from the fastening part from the side towards the cutting part. 1 shows a cutting tool according to the invention as a whole with the number 10.
- the cutting tool 10 comprises an oscillation drive 12, the drive shaft 18 of which can be driven to oscillate at a high frequency in the range between approximately 5,000 and 25,000 oscillations per minute with a small pivoting angle in the range between approximately 0.5 ° and 5 °.
- a cutting knife generally designated by the number 30, with a receiving opening (FIG. 2) is positively received on a polygon of the drive shaft 18 and fastened by a nut 20 on a thread of the drive shaft 18.
- the cutting part 34 has a first cutting edge 46, which is provided with a serrated edge, and on the opposite side a second cutting edge 48, which is provided with a straight grinding, both cutting edges 46, 48 at the outer end of the cutting part 34 to a rounded tip 40 converge.
- the cutting tool is used to cut through an adhesive bead 26 of a window pane 24, which is glued to a motor vehicle flange 22 on a motor vehicle.
- This can be a windshield, for example, which is connected to the A-pillar of the body by means of the circumferential adhesive bead 26 or is bonded in a completely sealing manner.
- This adhesive bead 26 generally consists of a special polyurethane, that has the highest possible UV resistance and high mechanical and long-term stability. By gluing the windshield to the A-pillar, the windshield contributes significantly to the stability of the body.
- the adhesive bead consists of such a tough and stable material that its complete severing to remove the windshield, for example after a stone chip damage, is associated with considerable effort, even if the advantageous effect of the oscillation drive 12 is taken into account.
- the cutting knife according to the invention makes it easier to cut through an adhesive bead in that the cutting edge 46 is provided with a serrated edge or with a sawtooth edge.
- the cutting knife 10 is preferably made from a flat blank by punching, which is suitably provided with a bend, so that the L-shaped cross section according to FIG. 3 results.
- the cutting tool 30 consists of a suitable knife steel, which is preferably hardened.
- the fastening part 32 has two side edges 52, 54 which surround the receiving opening 36, which is designed as a polygon, and converge towards the cutting part 34 in an approximately wedge shape.
- the fastening part 32 is in its transition region to the cutting part 34, ie in the region before the bend with which the fastening part 32 merges into the cutting part 34, both in the region of the side edge 52 and in the region of the Side edge 54 ground from both sides, so that both side edges 52, 54 are formed in the transition area to the cutting part 34 as straight cutting.
- hollow-groove-like depressions 42, 44 are formed from the center to both side edges 52, 54.
- the transition region in the region of the bend is provided with cutting edges on both sides, whereby an additional centering is formed by the fillet-like depressions 42, 44 on the inside of the bend, which serves as a guide for cutting through the adhesive bead 26.
- the cutting part 34 itself is preferably ground on both cutting edges 46, 48 from both sides, so that there is a spherical cross section of the cutting part, in addition to the area of a bevel 50 of the cutting part 34 on the inside of the bend, which runs outwards , the serrated edge of the cutting edge 46 is provided.
