Abstract: The shape parameter of stainless-steel heat exchanger plate is complex. Considering that the traditional stamping preparation process has a low efficiency, a roll forming process combined with stamping process was put forward. According to the bending theory of the stamping process and cold-bending formation process, mathematical models of rolling parameters about the corrugated structure were established and further optimized. The results show that the corrugated structure of heat exchanger can be formed by single-pass rolling process with a high preparation efficiency. Through the quantitative study of the deformation resilience, the processing accuracy of the physical parameters of the plate is basically satisfied with the technical standard.

Key words: heat exchanger plate, roll forming, stamping process, mathematical models, deformation resilience
