Abstract：To reduce the production cost and enhance the production efficiency of the clamping mechanism of the forging manipulator,this paper takes a certain type of forging manipulator as the research object.For its clamping mechanism,the angle is precisely measured based on engineering experience,and a drooping deflection angle model with an angle of 1° is established,and the clamping force model was theoretically derived using graphics.By establishing a full-scale model of the clamping mechanism for the forging manipulator,with the minimum weight of the clamping mechanism's jaws as the optimization objective,a multi-objective optimization algorithm based on the Design Exploration module is adopted to optimize design of the jaw structure by combing the mechanical model under the droop angle state with finite element simulation.By optimizing the upper end thickness,side height,and contact arc radius of the jaws,the goal of reducing jaw weight by 17%to the original model was ultimately achieved.Not only does it reduce processing and manufacturing costs,but also it provides theoretical reference and practical guidance for the optimization design of heavy-duty forging operating machines.
