The first step is as follows: as shown in fig. 6, the worker abuts the blank of the coaming 7 against the positioning block 23, then presses the start button 8, the PLC controls the extension of the piston rod of each first cylinder 31, as shown in fig. 3 and 4, the two bearings 36 abut against the two sides of the through hole 37 respectively in the process that the first cylinder 31 pushes the lifting plate 32 to move upwards, and then the inclined kidney-shaped hole 35 pushes the pressing plate 33 to move towards the positioning block 23, so that the coaming blank is pressed on the positioning block 23, and the feeding of the coaming blank is realized.

The second step is that: as shown in fig. 6, the PLC controls the two swing cylinders 22 at the two ends of the bending table 1 to rotate 90 degrees, so as to bend the two ends of the enclosing plate for the first time, and after the bending is completed, the piston rods of the two first cylinders 31 at the two ends of the bending table 1 retract so as to retract the two lifting plates 32 and the pressing plate 33 at the two ends into the through holes 37, so as to prevent the enclosing plate from being bent for the second time and colliding with the pressing plate 33.

The third step: the PLC controls the bending table 1 to bend the two swing cylinders 22 in the middle of the bending table 1 to rotate 90 degrees, the enclosing plates are bent for the second time, after the bending is completed, the swing cylinders 22 and the first cylinders 31 recover to the initial state, and workers perform blanking on the bent enclosing plates.
