Embodiment Construction
[0012] The single-piece slotting knife structure of the present invention is as figure 1 with figure 2 As shown, the disc-shaped knife is provided with a flat blade 2 on the specific 4 circumference, and the left hair lead 1 and the right hair lead 3 are welded on both sides of the rear end of the flat blade 2, and the left hair lead 1 and the right hair lead 3 are cutting knives. The height of the hair lead 1 and the right hair lead 3 is 1-2 mm higher than the flat edge, the cutting angle b of the left hair lead 1 and the right hair lead 3 is 45°, the elevation angle of the top hair lead edge of the left hair lead 1 and the right hair lead 3 a is 30°, specifically the flat blade 2 on the circumference of 4 is a left and right alternating structure.
[0013] The single-piece grooving knife of the present invention is provided with a hair guide structure, which can make the processing surface smoother for cork material processing, and the cutting is lighter and faster, and th...

The invention discloses a single-piece type slotting tool. Flat blades are arranged on the circumference of a disc-shaped tool body. Left burr guiders and right burr guiders are welded to the two sides of the rear ends of the flat blades. The cutting angle of the left burr guiders and the right burr guiders ranges from 30 degrees to 45 degrees. The elevation angle of top burr guider blades of theleft burr guiders and the right burr guiders is 30 degrees. The flat blades on the circumference of the tool body are of a left-right interaction structure. The burr guider structure is additionally arranged in the single-piece type slotting tool, soft wood materials can be machined, so that machined faces are smoother and cleaner, cutting is quicker, burrs are avoided, and the service life is longer. The cutting angle of 45 degrees is set for the burr guiders, the elevation angle of 30 degrees is obtained through grinding on the tops of the burr guider blades, and the tool is more resistant to impacts and more resistant to abrasion. Through left-right interaction of the flat blades, the cutting effect is better, and the service life of the tool is longer.
Description
technical field [0001] The invention relates to the technical field of cutting tools, in particular to a woodworking slotting knife. Background technique [0002] The woodworking slotting knife is used to make one or more grooves on the wood. The traditional slotting knife slots the wood through the flat edge of the knife, which will cause burrs on the surface and the tool life is short. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the existing slotting knife, the present invention provides a single-piece slotting knife. [0004] The technical scheme adopted by the present invention to achieve the above object is: a single-piece slotting knife, a flat blade is arranged on the specific circumference of the disc-shaped knife, and the left and right hair leads are welded on both sides of the rear end of the flat blade. [0005] The cutting angles of the left and right wool guides are 30°-45°. [0006] The elevation angle of t...
