Abstract In order to study the forming method and forming limit of H62 copper spiral corrugated tubes, ABAQUS simulation and experimental research on tube incremental forming are carried out. For the first time, the spiral corrugated bellows are processed by the incremental tube forming method. Through the combination of simulation and test, the process parameters of the incremental forming of the tube are optimized, and the forming precision and forming limit of the H62 copper spiral corrugated tube were improved by theoretical analysis. The test results show that when the single feed of the tool head is 0.50mm, the spindle speed is 10r/min, and the axial feed speed of the tool head is 6.7mm/s, the thread depth limit is increased. When the thread depth is 2.5mm, the forming quality of the bellows is the best, and when the thread depth is more than 6mm, the forming quality is remarkably lowered.
