Band saw blade

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...

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.

[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 consistent with the thickness of the back material, and then bending to the left or right (splitting teeth) to form a Arranged in a certain regularity. However, by bending to the left or right by mechanical means, it is difficult to ensure the accuracy of the tooth division because the material has a certain elasticity. During the cutting process, the roughness of the section cannot be guaranteed. At the same time Also easy to cut diagonally, resulting in wasted material

Furthermore, during the cutting process, due to the uneven cutting force received by each saw tooth, it is easy to cause tooth beating and edge chipping, and at the same time, the phenomenon of sawing and tooth pulling will occur during chip removal.
