The aluminum plate is sucked by the suction cup 51. Then, the output end of the first servo motor 9 drives the threaded rod 10 to rotate, so that the threaded rod 10 drives the moving block 11 and the first fixing plate 12 to move, causing the first fixing plate 12 to drive one end of the aluminum plate to insert between the base 7 and the cutter head 6.

Then the telescopic end of the second electric telescopic rod 39 drives the pressing block 40 to move upward. Then the feeding of the aluminum plate continues and the flanging is carried out. When it is necessary to carry out flanging on the other side, the top plate 18 is moved below the moving-in groove 46. Then the telescopic end of the fourth electric telescopic rod 43 pushes the fifth servo motor 44 and the second rotating block 45 to move downward through the moving-in groove 46 to below the top frame 37, so that the second rotating block 45 contacts the surface of the aluminum plate. Then the output end of the fifth servo motor 44 drives the second rotating block 45 to rotate. At the same time, the output end of the first electric telescopic rod 33 drives the suction seat 34 to rotate, so that the suction seat 34 and the air pump 35 drive the aluminum plate to rotate, adjusting the flanging position of the aluminum plate. Then the telescopic end of the fourth electric telescopic rod 43 drives the fifth servo motor 44 and the second rotating block 45 to move through the moving-in groove 46 to above the top frame 37, and the flanging work of the aluminum plate continues.
