Aiming at the characteristics of poor section shearing quality, low shearing efficiency and material utilization of traditional bar shearing equipment, the main reasons affecting the shearing section quality of blanks were analyzed. The bar shearing process with radial clamping and highspeed shearing was researched. The bar shearing equipment was designed and its principle, structure and control system were analyzed. The results shows that using the designed shearing equipment, the crosssection tilt, oval and roughness are significantly less than that of traditional bar shearing equipment, higher shearing quality, efficiency and material utilization are gotten.
