[0003] During the processing of the steel lining, it is necessary to perform flanging on the end of the steel lining. However, the existing flanging operation method is to flanging one end of the steel lining workpiece at a time, adjust the steel lining workpiece after flanging one end, and then perform flanging on the other end again. The flanging operation at both ends is inefficient, and the steel lining workpiece needs to be fixed first, released after flanging, and then fixed again to flip and adjust the steel lining workpiece back and forth, which is inconvenient to operate.
