The design and research on manufacturing the cutter for steel gratings shearing machine

Cutter is one of the main components of a steel gratings shearing machine.The cutter material,shape,and the heat treatment process are determined on the basis of the force of shear and mechanical calculation.With the application of the transverse shear theory and the sub-shear technology in design,the force of shear is reduced greatly.Through shear test and destructive test,the cutter material and shape are eventually determined,which is the basis of producing a steel gratings shearing machine.
