Abstract: The discrete clamp is used to replace the integral clamp in the traditional stretch forming process, and the stretch forming process of complex curved parts is studied. With the trapezoidal profile part and the double curved top part as the research objects, numerical simulation of the stretch forming process with the integral clamp and the discrete clamp is carried out respectively. The numerical simulation results show that: compared with the integral clamp, it is easier for the trapezoidal profile part to fit the die during stretch forming with the discrete clamp, and the distribution of strain and thickness of the formed part is more uniform; during forming of the double curved top part, with the same forming force, the sheet metal cannot fit the die completely with the integral clamp forming, while it can completely fit the die during stretch forming with the discrete clamp. When the forming force of the integral clamp is increased, the sheet metal still cannot fit the die completely, and the sheet metal is more likely to crack. Stretch forming tests are conducted for the trapezoidal profile part and the double curved top part with the discrete clamp stretch forming device, and good forming effect is realized, which is consistent with the numerical simulation results.
