[0031] Example
[0032] like figure 1 , 2 As shown in the figure, it is an electric-assisted segmental incremental forming device for titanium alloy sheets. In this embodiment, experiments are carried out using the machined die and the corresponding titanium alloy sheets to verify the electric-assisted segmental incremental forming of large and medium-sized titanium alloy sheets in actual production. In the forming process, the forming device includes: upper die base 1, lower die base 2, upper insulating pad 3, lower insulating pad 4, punch 5, concave die 6, titanium alloy sheet 7, sheet positioning pin 8, copper Electrode 9 , large current-carrying wire 10 , high-energy DC pulse power supply 11 , guide sleeve 12 and guide post 13 .
[0033] Among them, the upper die module and the lower die module are connected by the guide post 13, the titanium alloy sheet 7 is formed when the die is closed, and the temperature measuring device measures the temperature of the sheet and the...
