Abstract：

The forming quality of the plate type heat exchanger plate (PTHE) is closely related to the design of forming die and process parameters, and unreasonable die design and process parameters will cause the plate to thin excessively or even crack. In order to improve the forming quality of PTHE, the forming process of a PTHE was simulated by the DYNAFORM, and process parameters of punch including the clearance between punch and die, stamping speed and friction coefficient were selected and designed based on four sets of simulation results. By analyzing the forming limit diagrams and thickness nephograms, the forming results were evaluated by thickness reduction ratio, and the optimal forming effect was obtained. The simulation results show that the best forming result is obtained with stamping speed of 2000 mm·s-1, friction coefficient of 0.125 and clearance between punch and die of 0.87 mm.
