The left and right ends of the cylinder locking plate 23 are screwed to the left support plate 21 and the right support plate 22 on the corresponding sides, respectively. The lifting drive cylinder 31 is screwed and fastened to the cylinder locking plate 23.

[0049] Example 7, as Figures 1 to 4 As shown, the difference between this embodiment seven and embodiment one is that: the driving end of the lifting drive cylinder 31 is equipped with a pressure block pad 33, the pressure block pad 33 is arranged horizontally, and the lifting pressure block 32 is screwed and fastened to the lower surface of the pressure block pad 33.

[0050] Example 8 differs from Example 1 in that the pressing surfaces of the long-side shaping push block 51 and the short-side shaping push block 52 are respectively equipped with adhesive strips (not shown in the figure).

[0051] When the long-side shaping pusher 51 and the short-side shaping pusher 52 apply cold pressure to the corresponding long and short sides of the flat metal workpiece 100, the above-mentioned rubber strip structure can effectively prevent the flat metal workpiece 100 from being damaged.
