Inside both ends of the lower die base, a left bending module and a right bending module are respectively arranged. A central positioning block is arranged between the left bending module and the right bending module, and the central positioning block is connected to the lower die base by screws. Below both ends of the upper die base, bending knives are arranged. There are two bending knives, and the bending knives are connected to the upper die base by screws.
