Embodiment Construction
[0028] The production equipment of the thin-walled metal cylinder of the present embodiment includes a vertically placed frame 1, from the upper end to the lower end of the frame 1, a mandrel 2, a spinning part 3 and a punching die 4 are arranged successively, and the spinning The component 3 rotates around the mandrel 2, the spinning part 3 and the punching die 4 can slide up and down along the axis of the mandrel 2, the mandrel 2 is processed with a loop channel 5 extending to the mandrel working end 21, the loop channel 5 Connected with the cooling medium supply device (not shown in the figure), a heating element 6 is arranged in the punching die 4 .
[0029] Such as figure 2 As shown, the die-entry angle α of the punching die 4 is 5 degrees to 9.5 degrees. If the entry angle α is larger than 9.5 degrees, excessive shearing force will be generated on the sheet cylinder and it will be broken. If the mold entry angle α becomes smaller, the extrusion force on the cylinder b...
