For the large angle profile frame of a carrier rocket, the stretchwrap bending under the force control mode was simulated and experimented, and the influences of stretchwrap bending force on stress, strain distribution and springback were simulated and analyzed. The simulation results show that the tangential stress difference between outside and inside of profile section decreases, springback and warping decrease with the increase of stretchwrap bending force. However, the deformation, the thinning rate of wall thickness and the variation of crosssectional dimension increase with the increase of stretchwrap bending force. Considering all the above, the appropriate stretchwrap bending force 97.4 kN is selected. And the influences of the stretchwrap bending force, the first corner wrap and the amount of compensation on the accuracy of forming were analyzed by experiment. The results show that the larger the stretchwrap bending force and the amount of compensation are, the smaller the angle, flatness and radian clearance of parts are, and the higher the accuracy of part size is. Thus, the optimized bending process parameters are attained by experiments with the stretchwrap bending force 105 kN, the first corner wrap 65°and the amount of compensation 60 mm. Based on the above parameters, the qualified parts are formed with less quenching deformation, wist phenomenon and springback.
