Definitions
- the invention relates to a device for sharpening blades on knives, scissors and the like according to the preamble of the main claim.
- Sharpening knives or the like using hard metal has been known for a long time. Instead of hard metal, ceramic material is used, which has a hardness similar to that of hard metal, but is more brittle. Since sintered materials, such as hard metal or ceramic, are very expensive, only relatively small cutting plates made of sintered material are used in sharpening devices that have to be clamped in a holding device. Cutting plates made of sintered materials are manufactured in large quantities as inserts for milling tools, turning tools and the like. The sharpening of cutting edges on cutting devices such as knives, scissors, scythes etc.
- the bevel of the cutting edge is fixed in such knife sharpening devices and cannot be changed.
- a knife sharpener is known (DE G 93 06 427.6) in which a hard metal tool is injection molded onto a plastic handle. A circumferential bead is provided between the carbide tool and the handle, which should reduce the risk of injury.
- a disadvantage of this knife sharpener is that the hard metal tool is permanently connected to the handle. In addition, the geometry of the carbide tool leads to a cramped working posture.
- the device according to the invention for sharpening cutting edges with the characterizing features of the main claim has the advantage over the fact that a series-produced and therefore cheap hard metal l cutting blade is used as a hard metal tool and that this hard metal cutting plate is used in a corresponding tool holder having a handle is exchangeably fastened so that a blunt hard metal cutting plate can be easily replaced and a wide variety of cutting edges can be sharpened with one tool.
- the working posture can be influenced favorably by the choice of the cutting plate.
- the handle is ergonomically designed so that fatigue-free working is possible.
- the longitudinal section through the cutting plate is radially symmetrical (rhombic, rectangular, square, triangular) and the mounting hole is arranged in the center of the cutting plate, so that it can be fastened to the holding device in several positions and thus several cutting edges of the cutting plate can be used one after the other.
- coated (TiN) hard metal cutting inserts are used, so that the service life is increased.
- the device for deburring is used so that burrs can be removed easily and safely.
- An embodiment of the object of the invention is shown in the drawing as a device for sharpening cutting with dismantled hard metal cutting plate and described in more detail below.
- a knife sharpener is shown in an exploded view.
- a tool holder 3 On a handle 1 with a transverse bore 2 a tool holder 3 arranged with a wedge-shaped recess 4, which has a lateral boundary wall.
- a bead 6 is provided between tool holder 3 and handle 1 in order to avoid injuries when the cutting device slips.
- a hard metal insert 7 can be inserted, which has a rhombic longitudinal cross section and a central bore 8, via which this hard metal insert can be screwed to the base of the recess 5 by means of a screw, not shown. Because of the radial symmetry of the cutting plate 7 with respect to the central bore 8, the cutting plate 7 can be mounted in two positions and thus all 4 cutting edges 9 of the same can be used.
- the sharpening of cutting edges takes place in that a cutting edge 9 of a cutting plate 7 fastened in the tool holder 3 is guided over the cutting surface or the longitudinal surface of a cutting device and thereby causes material removal by scraping or cutting.
- the cutting surface connects the two parallel or wedge-shaped longitudinal surfaces. The cutting surface and one of the longitudinal surfaces form the cutting edge of the cutting edge.
