Problems solved by technology

[0002] At present, the tooth shape of woodworking hand saw blades, panel saw blades and band saw blades seen in the market has a vertical front and side of the teeth, and the resistance is large when sawing, which not only makes it very laborious to use, but also causes the saw blade to break due to the large resistance In some cases, the service life of the saw blade is shortened. For the above problems, there is still no good solution

Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention will be further described:

[0012] Such as Figure 1 ~ Figure 3 As shown, the wedge-shaped toothed woodworking saw blade includes a saw blade body 1, and saw teeth 2 are continuously arranged on one side edge of the saw blade body 1. The position is staggered forward and backward. front and rear staggered settings, that is, from figure 1 When viewed from the front view, if the inclined surface of the first sawtooth can be seen from the front, the inclined surface of the second sawtooth can be seen from the rear, the third sawtooth is the same as the first sawtooth, and the fourth sawtooth Same for the second sawtooth, and so on.

[0013] The rake angle of the sawtooth 2 is 90°, and the rake angle is the angle between the front side of the sawtooth 2 and the horizontal base surface, that is, figure 1 The angle a shown; the back angle of the sawtooth 2 is 25-30°, and the back angle is the angle bet...

Abstract

The invention discloses a wedge angle tooth-shaped woodworking saw blade and belongs to woodworking tools. The wedge angle tooth-shaped woodworking saw blade comprises a saw blade body, and sawteeth are continuously arranged on the edge of one side of the saw blade body. The wedge angle tooth-shaped woodworking saw blade is characterized in that the sides and the top surfaces of the sawteeth are inclined planes, and the positions of the inclined planes of the adjacent sawteeth are staggered in a front-and-back mode. The front angles of the sawteeth are 90 degrees, the rear angles are 25-30 degrees, the tooth side angles are 25 degrees, and the wedge angles are 45-50 degrees. Cutting resistance is greatly reduced when wood is cut, not only does the saw blade save labor in use, but also the service life of the saw blade is prolonged, and the saw blade can serve as a woodworking hand saw blade, a board saw blade and a belt saw blade and have extremely good popularization application value.

Description

technical field [0001] The invention relates to a woodworking saw blade, in particular to a wedge-shaped toothed woodworking saw blade, which belongs to woodworking tools. Background technique [0002] At present, the tooth shape of woodworking hand saw blades, panel saw blades and band saw blades seen in the market has a vertical front and side of the teeth, and the resistance is large when sawing, which not only makes it very laborious to use, but also causes the saw blade to break due to the large resistance In some cases, the service life of the saw blade is shortened. For the above problems, there is no good solution at present. Contents of the invention [0003] The object of the present invention is to provide a wedge-shaped toothed woodworking saw blade, which greatly reduces cutting resistance when sawing wood. [0004] The technical scheme adopted by the present invention to solve the technical problem is: the wedge-shaped toothed woodworking saw blade includes ...
