[0059] During operation, the cut-to-length steel coil is first unwound by the uncoiler 1 and fed into the leveling and length-measuring feeder 2 for leveling. The sheet metal then enters the combined punching and labeling machine 3 and hydraulic cutter 4, where, according to pre-programmed procedures for different specifications and hole positions, the sheet metal is punched, logo-stamped, and cut. The sheet metal then passes along the front support roller 5 to the coiling machine 6 for double-sided coiling. After coiling, the sheet metal is palletized into stacks by the rear support roller 7 and the truss palletizer 8, according to a specific cycle. The finished seat drum panels are then manually fed into the bending and welding machine 9 for two bends, forming the flat sheet into a closed rectangle. Laser welding then automatically welds the seams. The sheet metal then moves to the stamping and expanding machine 10 and the shutter stamping machine 11 for expanding the upper portion of the seat drum and stamping the shutters. Finally, manual palletizing is performed at the manual stacking station 12, completing the entire process.
