Abstract：

In order to study the influences of different tooth profile parameters for saw blade on the saw shear performance of sawtooth, based on the finite element platform ABAQUS, the finite element model of sawtooth in saw shear machine was established. Then, compared with saw shear performances of two different tooth profiles during the saw shear process, the influences of different tooth rake angle, tooth back angle and radius of tooth root fillet on the saw shear performance were studied by the single factor control method, and relevant verification experiment was conducted at the same time. The results show that the simulation and experiment results are in good agreement, and their errors are within a reasonable range to verify the reliability of finite element model. Furthermore, the arc tooth profile is more suitable for the tooth profile of hot saw shear machine. During the saw shear process, with the increasing of tooth rake angle, the sawing force and the shearing force of single tooth gradually decrease, and with the increasing of tooth back angle, the sawing force and the shearing force of single tooth hardly change. In addition, it is concluded that the saw shear performance are better when the tooth rake angle is 0°-2°, the tooth back angle is 8°-12°, and the radius of tooth root fillet is 2.6 mm in the study range.
