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

Angle of wedge profile of tooth woodworking blade

Technical field

The present invention relates to a kind of woodworking blade, specifically a kind of angle of wedge profile of tooth woodworking blade, belongs to wood working tool.

Background technology

At present, the carpenter who is commercially available uses the profile of tooth of hand saw blade, bladed saw bar and bands for band, before its tooth portion and lateral vertical, during sawing, resistance is large, while not only causing using, require great effort very much, also can, because of the large situation that occurs saw blade fracture of resistance, shorten the service life of saw blade, for the problems referred to above, the solution also not had at present.

Summary of the invention

The object of the present invention is to provide a kind of angle of wedge profile of tooth woodworking blade, during this saw blade sawing timber, reduced greatly Cutting Drag.

The present invention solves the technical scheme that its technical problem takes: angle of wedge profile of tooth woodworking blade, comprise saw blade body, one lateral edges continuous arrangement of saw blade body has sawtooth, and side and the end face of described sawtooth are inclined plane, and adjacent sawtooth top incline present position is for being staggered front to back.

The anterior angle of described sawtooth is 90 °, and relief angle is 25~30 °, and flank angle is 25 °, and the angle of wedge is 45~50 °.

Compared with prior art, the present invention has following outstanding beneficial effect: because side and the end face of sawtooth is inclined plane, formed angle of wedge profile of tooth, reduced greatly Cutting Drag while making sawing timber, not only use laborsavingly, and extended service life of saw blade.

Accompanying drawing explanation

Fig. 1 is front view of the present invention;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the top view of Fig. 1.

In figure: 1 saw blade body, 2 sawtooth.

The specific embodiment

Below in conjunction with Figure of description, the invention will be further described:

As shown in FIG. 1 to 3, angle of wedge profile of tooth woodworking blade, comprises saw blade body 1, and a lateral edges continuous arrangement of saw blade body 1 has sawtooth 2, and side and the end face of described sawtooth 2 are inclined plane, and adjacent sawtooth 2 top incline present positions are for being staggered front to back.Be staggered front to back setting, while seeing from Fig. 1 front view, if the inclined plane of first sawtooth can be seen from dead ahead, the inclined plane of second sawtooth can be seen from behind, the 3rd sawtooth is identical with first sawtooth, and the 4th sawtooth is identical with second sawtooth, by that analogy.

The anterior angle of described sawtooth 2 is 90 °, and described anterior angle is the leading flank of sawtooth 2 and the angle between horizontal basal plane, i.e. angle a shown in Fig. 1; The relief angle of sawtooth 2 is 25~30 °, and described relief angle is the extended line of sawtooth 2 top edge and the angle between horizontal datum, i.e. angle b shown in Fig. 1; The flank angle of sawtooth 2 is 25 °, and described flank angle is the angle between sawtooth 2 top surface inclination faces and horizontal basal plane, i.e. angle c shown in Fig. 2; The angle of wedge of sawtooth 2 is 45~50 °, and the described angle of wedge is the angle between laterally inclined of sawtooth 2 and horizontal basal plane, i.e. angle d shown in Fig. 3.

During use, because sawtooth 2 has formed angle of wedge profile of tooth, while making sawing timber, reduce greatly Cutting Drag, not only used laborsavingly, and extended service life of saw blade.The size of tooth depth and tooth pitch, can be according to using object and saw blade feature to determine voluntarily.This profile of tooth can be applied to Woodworking hand saw bar, bladed saw bar and bands for band, and saw blade material also can be selected bimetallic or monometallic.

The above, principles more of the present invention just explain through diagrams, this description is not that in concrete structure and the scope of application described shown in the present invention will being confined to, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the present invention applies for.

Except technical characterictic described in description, all the other technical characterictics are those skilled in the art's known technology.

Claims (2)

1. angle of wedge profile of tooth woodworking blade, comprises saw blade body, and a lateral edges continuous arrangement of saw blade body has sawtooth, it is characterized in that, side and the end face of described sawtooth are inclined plane, and adjacent sawtooth top incline present position is for being staggered front to back.
2. angle of wedge profile of tooth woodworking blade according to claim 1, is characterized in that, the anterior angle of described sawtooth is 90 °, and relief angle is 25~30 °, and flank angle is 25 °, and the angle of wedge is 45~50 °.
