Abstract：

In this paper,the deformation principle of blank shearing has been analysed with a new opinion The main factors affecting the sheared section quality of the blank have been pointed out,too The methods for improving the quality are also raised In the end of this paper,we introduced a mechanism that can compensate automatically the volume tolerance of the sheared blank caused by the dimeter tolerance of the hot rolling rod
