Abstract
The utility model discloses a wood-iron dual-purpose saw blade which comprises a saw blade body, wherein fixed cutter teeth are distributed on the periphery of the saw blade body, the cutter teeth comprise left oblique teeth, right oblique teeth and flat teeth which are distributed in a circulating sequence, and the height of each flat tooth is 0.2mm lower than that of each left oblique tooth and each right oblique tooth. The left and right helical teeth of the wood-iron dual-purpose saw blade not only ensure the wood cutting performance and the wood cutting speed, but also are beneficial to cutting iron metal by combining with the flat teeth, and the height of the flat teeth is 0.2mm lower than that of the left and right helical teeth, so that the anti-collapse performance of the flat teeth can be improved, and the iron cutting performance of the flat teeth is improved.
Description
Technical Field
The utility model relates to the technical field of saw blades, in particular to a saw blade which can be used for cutting wood and ferrous metal simultaneously.
Background
The prior saw blade for cutting ferrous metal has the problems that the cutting teeth of the saw blade are generally half-chamfered teeth, trapezoidal flat teeth or flat teeth, the front angle of the cutting edge of the cutting teeth is generally 0 degree, and the cutting speed is low due to insufficient sharpness when the saw blade is used for cutting wood; the cutter teeth of the wood cutting saw blade are generally left and right inclined teeth, the front angle is 10-20 degrees, and the problems of blade breakage and tooth breakage are easy to occur when iron is cut.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a saw blade which can be used for cutting wood and ferrous metal simultaneously.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a dual-purpose saw bit of wood iron, including the saw bit body, fixed sword tooth, its characterized in that have been laid to the periphery of body: the cutter teeth comprise left oblique teeth, right oblique teeth and flat teeth which are arranged in a circulating sequence, wherein the height of the flat teeth is 0.2mm lower than that of the left oblique teeth and the right oblique teeth.
On the basis, the tooth tips of the left oblique tooth and the right oblique tooth are chamfered, the chamfer angle is 30 degrees, and the bevel angle of the left oblique tooth and the right oblique tooth is 15 degrees.
On the basis, the front angle of the cutting edge of the cutter tooth is 5 degrees.
The utility model has the following beneficial effects: the left and right helical teeth of the wood-iron dual-purpose saw blade not only ensure the wood cutting performance and the wood cutting speed, but also are beneficial to cutting iron metal by combining with the flat teeth, and the height of the flat teeth is 0.2mm lower than that of the left and right helical teeth, so that the anti-collapse performance of the flat teeth can be improved, and the iron cutting performance of the flat teeth is improved.
Drawings
FIG. 1 is a schematic structural view of a wood-iron dual-purpose saw blade according to the present invention;
FIG. 2 is a tooth profile of the teeth of the wood-iron dual-purpose saw blade of the present invention.
Detailed Description
As shown in fig. 1 and 2, the wood-iron dual-purpose saw blade comprises a saw blade body 1, wherein fixed cutter teeth 2 are distributed on the periphery of the body 1. The cutter teeth 2 comprise left oblique teeth 21, right oblique teeth 22 and flat teeth 23 which are arranged in a circulating sequence, wherein the height of the flat teeth 23 is 0.2mm lower than that of the left oblique teeth 21 and the right oblique teeth 22. The left and right helical teeth 21 and 22 not only ensure wood cutting performance and wood cutting speed, but also are beneficial to cutting ferrous metal by combining the flat teeth 23, and the height of the flat teeth 23 is 0.2mm lower than that of the left and right helical teeth, so that the collapse resistance of the helical teeth can be improved, and the iron cutting performance of the helical teeth is improved.
The tooth tops of the left helical tooth 21 and the right helical tooth 22 are chamfered, the chamfer angle is 30 degrees, and the bevel angle of the left helical tooth and the right helical tooth is 15 degrees. Therefore, the sharpness of the cutter teeth can be improved, and the phenomenon that the teeth are too sharp to cause tipping can be avoided.
In order to further improve the iron cutting performance, the front angle 3 of the cutting edge of the cutter tooth 2 is 5 degrees.
Claims (3)
