Embodiment 1

[0020] Example 1: The 54mm wide saw blade is produced by the manufacturing method of the bimetallic saw blade saw tooth, the raw material is a bimetallic composite steel strip whose back is special spring steel and the teeth are high-speed steel, and the width is 54mm; the teeth can be M42 high-speed steel; production process steps for:

[0021] (1) Carry out laser cutting and forming of the saw blade raw material bimetal composite steel strip according to the tooth shape:

[0022] Use a laser cutting machine to cut the tooth shape, and cut the required tooth shape through CNC programming; the laser cutting and shaping of the tooth shape is carried out continuously according to the beat, cutting 5 or more tooth pitches per beat, cutting 5-8 meters per minute, and the tooth tip Form an arc of 0.05mm-0.1mm;

[0023] Laser cutting equipment can choose German Trumpf Trulaser3030 laser cutting machine, or Swiss Bystronic laser cutting machine, or other suitable laser cutting...

Abstract

The invention relates to a making method for cutting sawteeth of a dual metal saw. The making method comprises the following steps of: performing laser cutting or punching or linear cutting forming on a dual metal composite steel band serving as a saw raw material according to the tooth shape; quenching and tempering the cut saw so as to enhance the hardness of a tooth part; grinding and milling a front corner and a rear corner of the thermally processed sawtooth-shaped tooth part so as to form sharp tooth tips; and dividing the teeth. By adopting laser cutting to form the sawtooth, the making method improves the production efficiency, reduces the machining cost and simultaneously solves the problem of overheating of the quenched tooth tips caused by burrs on the tooth tips; furthermore, as the tooth part is separately milled to form the sharp tooth tips, the saw in the use has no run-in period, thereby improving the cutting efficiency of the dual metal saw and prolonging the service lifetime of the dual metal saw.

Description

technical field [0001] The invention relates to a method for manufacturing bimetallic saw blades, in particular to a method for manufacturing sawtooth of bimetallic saw blades. Background technique [0002] Ordinary bimetallic saw blades are manufactured by milling (or grinding), splitting, quenching and tempering heat treatment of bimetallic composite steel strips (see figure 1 ) is manufactured, and the sawtooth forming manufacturing method generally uses multiple saw blade raw materials to overlap together for milling or grinding. [0003] The disadvantages of adopting the above-mentioned sawtooth milling manufacturing process are: the efficiency of milling the tooth profile with large tooth pitch is low and the milling cutter is consumed, the tip of the tooth is not sharp enough, and burrs are easy to form on the tip of the tooth, which will cause the tip of the tooth to overheat during quenching. When using the saw blade, customers must carry out running in. Contents...
