Problems solved by technology

With the continuous improvement of the profile to be cut, the saw blades of the above two tooth shapes are no longer suitable for the current profile cutting. The frequent problems are that the service life of the saw blade is short, and the end surface of the profile to be cut has unevenness and burrs. The operating costs of end users are increasing, and new products are expected to replace them

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 As shown, the multifunctional carbide saw blade used in the door, window and woodworking industries includes a number of arc-shaped teeth 2 arranged in a staggered front and rear on the periphery of the saw blade body 1, and all arc-shaped teeth 2 are of equal height, that is, all arc-shaped teeth 2 The distance from the central hole of the saw blade body 1 to the tip of the arc-shaped tooth is the same.

[0022] The arc-shaped tooth 2 means that all the rake angles of the teeth on the saw blade are arc-shaped. Each arc-shaped tooth 2 is composed of two small arc-shaped teeth staggered forward and backward (not shown in the figure). The included angle between the tangent to the top of the curve 3 on the curved surface of the curved tooth 2 and the line connecting the top to the center of the saw blade is 0°-27°.

[0023] The ...

Abstract

The invention discloses a multifunctional hard alloy saw blade for doors and windows as well as woodworking industry. The multifunctional hard alloy saw blade comprises a plurality of arc-shaped teeth which are located on the peripheral edge of a saw blade body and arranged in a front-back staggered manner, wherein the heights of all the arc-shaped teeth are equal, that is, the distance between a center hole of the saw blade body and a tooth top of each arc-shaped tooth is the same; for the arc-shaped teeth, tooth-shaped front angles of the saw blade are all arc-shaped; each arc-shaped tooth is formed by two small arc-shaped teeth which are arranged in a front-back staggered manner; an included angle between a tangent line at the top end of a curve on the arc-shaped surface of each arc-shaped tooth and a connecting line from the top end to the center of the saw blade is 0-27 degrees. The saw blade can be multifunctional, can be used for cutting aluminum and aluminum alloys and can also be used for cutting woodworking products, the service life of the saw blade can be prolonged, and concave-convex and burr phenomena and other phenomena during cutting can also be eliminated.

Description

technical field [0001] The invention relates to a saw blade, in particular to a multifunctional hard alloy saw blade used in door, window and woodworking industries. Background technique [0002] At present, the cemented carbide saw blades used in the above two industries at home and abroad are mainly divided into saw blades for cutting aluminum and aluminum alloys and saw blades for cutting woodworking products. The specifications and models of the two saw blades are roughly the same. However, the carbide tooth and tooth shape of the saw blade are very different, as far as the tooth shape of the saw blade for cutting aluminum and aluminum alloy is concerned. At present, saw blades at home and abroad are basically the same, that is, high and low teeth, also called "T" flat teeth. In the woodworking industry, the saw blade is composed of left and right teeth and high and low teeth. With the continuous improvement of the profile to be cut, the saw blades of the above two too...
