Description

Tungsten-cobalt alloy saw blade

Technical Field

The utility model relates to a saw bit technical field, in particular to tungsten cobalt alloy saw bit.

Background

The circular saw blade is a cutting tool commonly used, in order to guarantee the intensity of cutting in the actual work, generally adopt high-speed steel to make, and the circular saw tooth generally all cooperates and cuts in the circular cutter dish, and the thickness of circular cutter dish is thinner, and the feed volume of conveniently cutting like this increases. However, in the design and manufacture process of the circular saw teeth, the sizes and the shapes of the sawteeth are the same, although the circular saw teeth have the advantages of simple blade processing and convenient cutting, when some objects with larger diameters or thicknesses are cut, due to the fact that the thickness of the circular cutter head is thin, and the chip grooves between the sawteeth and the sawteeth are small, the phenomena of tooth breakage and tooth clamping can often occur, cutting efficiency is low, and the service life of the sawteeth of the circular saw blade is shortened.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a tungsten cobalt alloy saw bit, the tool bit welding is inseparable, and the sawtooth cutting is smooth in the use, reduces the probability that the saw bit is blockked up.

In order to solve the technical problem, the utility model discloses a technical scheme does:

the utility model provides a wolfram cobalt alloy saw bit, the saw bit includes the saw bit base member, be equipped with the mounting hole on the saw bit base member, be equipped with a plurality of sawtooth on the outer circumference of saw bit base member, it is adjacent saw bit inter-dental space is equipped with the chip removal sawtooth, be equipped with the chip groove between chip removal sawtooth and adjacent sawtooth, be equipped with the tool bit on the sawtooth, the tool bit includes the cutting edge, the chip removal sawtooth includes chip removal sawtooth cutting edge, distance between chip removal sawtooth cutting edge and the saw bit base member center is less than the distance between cutting edge and the saw bit base member center.

Preferably, the tool bit further comprises a cutting edge base body, and the two side surfaces of the cutting edge base body are provided with mounting base bodies.

Preferably, the cutting base body is made of a tungsten-cobalt alloy material.

Preferably, the mounting base is made of common steel.

Preferably, the number of the mounting substrates is two.

Preferably, the distance between the opposite faces of the two mounting bases is equal to the thickness of the saw blade base.

By adopting the technical scheme, the saw blade is provided with the chip removal saw teeth, so that cutting chips are easier to discharge in the cutting operation of the saw blade, the saw blade is not easy to block, and the cutting performance and the service life of the saw blade can be improved due to the arrangement of the cutter head.
