Bionic bimetallic band saw blade

Abstract

A bionic bimetallic band saw blade belongs to the technical field of cutting tools. The bionic bimetallic band saw blade is formed by fixedly connecting sawteeth with a saw blade body. The sawteeth have a geometrical structure characteristic of badger canine teeth, wherein a tooth profile of a single tooth pitch of the tooth part of the saw blade is formed by a front tooth form curve, a back tooth form curve and a tooth bottom arc that are smoothly connected to each other, thereby forming a bionic saw tooth; an arc radius of each tooth bottom arc is 1.51 to 4.67 mm; a tooth graduation quantity is 0.32-0.34 mm; 1 to 9 tooth pitches are present; tooth graduation forms of the sawteeth are left tooth graduation, right tooth graduation, left tooth graduation, right tooth graduation and straight tooth graduation in sequence; tooth depths range from 3.39 to 6.20 mm; a horizontal distance between each tooth crown and the center of each tooth bottom arc is 1.26 to 4.3 mm; the sawteeth are made of M42 high-speed steel; the saw blade body is made of Rm80 steel. The bionic bimetallic band saw blade is characterized in that the front and rear portions of the tooth forms of the sawteeth are of the bionic curve structures such that the sawteeth are sharper with higher cutting efficiency, and the service life of the saw blade is longer.

Description

technical field [0001] The invention belongs to the technical field of cutting tools, and in particular relates to a bionic bimetallic band saw blade. Background technique [0002] Bimetal band saw blade is the most commonly used tool for cutting workpiece materials, mainly used for sawing metal profiles, and is the starting point of metal cutting. With the continuous increase in the variety of sawing materials, higher requirements are also put forward for band saw blades. The band saw blade is composed of saw teeth and saw blade body. The design of the saw teeth is the key to the performance of the bimetallic band saw blade. When bimetallic band saw blades cut metal bars, pipes, and profiles, due to the different diameters, wall thicknesses, and shapes of the materials, the impact on the teeth is relatively large, especially when cutting large-diameter metal bars and thick-walled pipes. The vibration generated when it is combined with the profiled material has a greater i...

AI Technical Summary

Problems solved by technology

When bimetallic band saw blades cut metal bars, pipes, and profiles, due to the different diameters, wall thicknesses, and shapes of the materials, the impact on the teeth is relatively large, especially when cutting large-diameter metal bars and thick-walled pipes. The vibration generated when it is combined with the profiled material has a greater impact on the teeth of the bimetallic band saw blade. Ordinary band saw blades cannot withstand this impact, and the damage to the saw teeth is great, resulting in low cutting speed and cutting efficiency, poor quality, Short service life of the saw blade
