Sea gull-shaped alloy sheet impressing mechanism

The utility model discloses a sea-gull-shaped alloy sheet impressing mechanism which comprises a machine frame, a first pressing roller, a second pressing roller, a third pressing roller, a fourth pressing roller and a fifth pressing roller are sequentially and rotationally installed on the machine frame from the feeding end to the discharging end, and the first pressing roller, the second pressing roller, the third pressing roller, the fourth pressing roller and the fifth pressing roller are provided with grooves and protrusions which surround in the circumferential direction respectively. Due to the fact that the depths of the grooves in the first compression roller to the fifth compression roller are gradually deepened in an arithmetic progression mode, and the heights of the protrusions on the first compression roller to the fifth compression roller are gradually increased in an arithmetic progression mode, impressing traces on the alloy sheet are gradually deepened in the working process, impressing is s
