Abstract
The utility model discloses an anti-nailing type quick-cutting saw blade which comprises a saw blade body, wherein fixed cutter teeth are arranged on the periphery of the saw blade body, each cutter tooth comprises a first left helical tooth, a first right helical tooth, a second left helical tooth, a second right helical tooth and sharp teeth which are arranged in a circulating sequence, and tooth tips of the first left helical tooth, the first right helical tooth, the second left helical tooth and the second right helical tooth are chamfered. The cutter teeth of the nail-resistant quick-cutting saw blade adopt the cutter teeth of various combinations of the first left helical teeth, the first right helical teeth, the second left helical teeth, the second right helical teeth, the sharp teeth and the like, so that the cutting load of single teeth can be reduced, the tooth tips of the first left helical teeth, the first right helical teeth, the second left helical teeth and the second right helical teeth are chamfered, the cutter teeth can be prevented from tipping, the nail-resistant performance of the cutter teeth is improved, the bevel angle of the left helical teeth and the right helical teeth can be increased, the sharpness of the cutter teeth is increased, and the cutting speed of the saw blade is further improved.
Description
Technical Field
The utility model relates to the technical field of saw blades, in particular to a wood quick-cutting saw blade with nail resistance.
Background
The existing anti-nailing circular saw blade is mainly realized by reducing the oblique angles (generally 10 degrees) of left and right oblique teeth with sharpness and then matching with alloy with strong anti-nailing capability, so that the cutting speed is low at the cost of sacrificing the sharpness of the saw blade, and the problem that the service life is too short due to easy tipping of the tooth tips of cutter teeth when continuous nailing or rotating speed is reduced is solved.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a saw blade capable of improving the nailing resistance and the cutting speed.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides an anti nail formula quick-cut saw bit, including the saw bit body, the fixed sword tooth has been laid to the periphery of body, its characterized in that: the cutter teeth comprise first left helical teeth, first right helical teeth, second left helical teeth, second right helical teeth and sharp teeth which are distributed in a circulating sequence, and tooth tip chamfers of the first left helical teeth, the first right helical teeth, the second left helical teeth and the second right helical teeth.
Preferably, the angle of the tooth tip chamfer is 20 °.
Preferably, the angles of the first left helical tooth, the first right helical tooth, the second left helical tooth and the second right helical tooth are 13 degrees, and the angles of the oblique angles of the two sides of the sharp teeth are 20 degrees.
The utility model has the beneficial effects that: the cutter teeth of the nail-resistant quick-cutting saw blade adopt the cutter teeth of various combinations of the first left helical teeth, the first right helical teeth, the second left helical teeth, the second right helical teeth, the sharp teeth and the like, so that the cutting load of single teeth can be reduced, the tooth tips of the first left helical teeth, the first right helical teeth, the second left helical teeth and the second right helical teeth are chamfered, the cutter teeth can be prevented from tipping, the nail-resistant performance of the cutter teeth is improved, the bevel angle of the left helical teeth and the right helical teeth can be increased, the sharpness of the cutter teeth is increased, and the cutting speed of the saw blade is further improved.

FIG. 1 is a schematic view of the structure of the anti-nailing fast-cutting saw blade of the present utility model;
fig. 2 is a tooth profile of the spike resistant quick cutting saw blade tooth of the present utility model.
Detailed Description
As shown in fig. 1 and 2, the nail-resistant quick-cutting saw blade comprises a saw blade body 1, and fixed cutter teeth 2 are distributed on the periphery of the saw blade body 1. In the present utility model, the cutter teeth 2 include a first left helical tooth 21, a first right helical tooth 22, a second left helical tooth 23, a second right helical tooth 24, and a sharp tooth 25, which are circularly arranged in sequence, and the tooth tips of the first left helical tooth 21, the first right helical tooth 22, the second left helical tooth 23, and the second right helical tooth 24 are chamfered.
The cutter teeth of various combinations such as the first left helical tooth 21, the first right helical tooth 22, the second left helical tooth 23, the second right helical tooth 24 and the sharp teeth 25 are adopted, the cutting load of single teeth can be reduced, the tooth tips of the first left helical tooth 21, the first right helical tooth 22, the second left helical tooth 23 and the second right helical tooth 24 are chamfered, the cutter teeth can be prevented from tipping, the nail resistance is improved, the bevel angle of the left helical tooth and the right helical tooth can be increased, the sharpness of the cutter teeth 2 is increased, and the cutting speed of a saw blade is improved.
Specifically, the angle of tooth point chamfer is 20, the angle of first left helical tooth, first right helical tooth, second left helical tooth and second right helical tooth oblique angle is 13, when promoting cutter tooth sharpness, can be far away again avoid the tooth point too sharp and arouse the tipping. The bevel angles at the two sides of the sharp teeth 25 are 20 degrees, and the bevel teeth play a role in digging the bottom and ditching during cutting, so that the cutting load of the front bevel teeth is reduced.
