Problems solved by technology

Split-toothed band saw blades are formed by grinding the teeth to ensure that the width of the tooth tips is consistent with the thickness of the back material, and then bending to the left or right (splitting teeth) to form a regular arrangement. But by mechanical means to the left Or bend to the right, because the material has a certain degree of resilience, it is difficult to ensure the accuracy of the split teeth; and for very high cutting precision and fast cutting, split-toothed band saw blades are difficult to use.

Example Embodiment

[0036] A non-tooth-shaped band saw blade, including consecutively arranged saw teeth, adjacent 4-9 saw teeth as a group, such as Figure 5 As shown, the back corner surface 8 and the side corner surface 9 of each saw tooth form an included angle chamfer 6, and the length of the hypotenuse of the included angle chamfer is sequentially reduced. Each saw tooth 1, 2, 3, 4 has a slot 5, the number of slot 5 gradually increases, the number range is 2-7, and the width and depth of slot 5 gradually decrease. The angle between the side angle surface of the band saw blade and the width direction of the band saw blade (radial side angle γ) is 5-10°, and the angle between the side angle surface and the length direction of the band saw blade (tangential side angle δ) is 5-10° . The angle of the chamfer formed by the back angle surface of the band saw blade and the side angle surface is the same, the range is 45-60°

Abstract

The invention discloses a band saw blade which comprises multiple groups of sawteeth in continuous arrangement. Each group of the sawteeth includes multiple sawteeth, a rear angle face and a side angle face of each sawtooth form an included angle chamfer, and a groove formed along the length direction of the band saw blade is formed in a tooth tip of each sawtooth. Cut-machined surface coarseness is improved, cutting force borne by a toothed material is lowered, saw binding, tooth drawing and blade breaking are avoided, and service life of the band saw blade is prolonged.

Description

technical field [0001] The invention relates to a band saw blade, which belongs to the field of sawing metal knives, in particular to a band saw blade with no teeth. Background technique [0002] At present, there are more toothed band saw blades on the market. Split-toothed band saw blades are formed by grinding the teeth to ensure that the width of the tooth tips is consistent with the thickness of the back material, and then bending to the left or right (splitting teeth) to form a regular arrangement. But by mechanical means to the left Or bend to the right, because the material has a certain degree of resilience, it is difficult to guarantee the accuracy of the teeth; and for very high cutting precision and fast cutting, the split-tooth band saw blade is difficult to use. [0003] At present, the band saw blades are mainly split-toothed band saw blades. The split-toothed bandsaw blades are formed by grinding the teeth to ensure that the width of the tooth tip is consist...
