Abstract
The invention discloses a bionic disk saw. The bionic disk saw comprises a disk saw substrate 1 and saw teeth 2 having bionic structures, wherein the saw teeth 2 are fixed on the disk saw substrate 1 by using rivets through saw tooth installing holes 3. The parameters of the saw teeth 2 are selected according to common specifications of a disk saw blade; the ratio of the tooth height H to the width b of the saw blade is 0.6-1.2; the tooth height refers to the vertical distance between a tooth point to a junction of a tooth root and the disk substrate; the tooth width refers to the linear distance of the saw teeth on the circular arc of the disk substrate. The saw teeth have the characteristics that the upper parts of the saw teeth are piercing segments, and account for 0.2-0.3 of a cutting edge curve, and x is greater than 0 and smaller than 0.8 on the curve; a cutting segment accounts for 0.7-0.8 of the cutting edge curve, and x is greater than 0 and smaller than 3 on the curve; the back parts of the saw teeth are sliding segments, and x is greater than 0 and smaller than 5.6 on the curve; in the equations, the unit is mm. The hardness of the saw teeth is treated, so that a hardness gradient is formed on the saw teeth from the cutting edge to the back. Compared with an ordinary hard alloy disk saw, the bionic disk saw has the advantages of high sawing efficiency, low resistance, high shock resistance and low energy consumption.
