Abstract：

The influence of crowned teeth of jaw on gripping force of forging manipulator was analyzed, and the results show that the jaw with crowned teeth is more effective and labor-saving than the flat jaw when the workpiece is clamped. The yield stress of hot workpiece was determined by analyzing the deformation of squeezed hot workpiece. The simplified model of working condition when the workpiece was clamped by jaws was simplified and corresponding force was analyzed，then the calculated method of gripping force of the forging manipulator with crowned teeth was obtained.The forging manipulators with 300，400，800kN were calculated,and the results show that the calculation method is effective.
