The blade of the paper cutter sometimes deforms, so what causes it?
        It is best to put it in the middle, because the bending machine is the two cylinders acting on the slider at the same time, so that the slider is balanced and pressed down, so that the sheet is bent, and other upper molds do not need to be removed. The deformation of your mold blade may be:
        ① The upper mold has been used for too long, and it has been worn hard;
        ② The gap between the upper and lower molds is too small, the upper and lower molds kill each other, the gap should be slightly larger than the thickness of the bent plate;
        ③ The balance of the two cylinders is slightly worse, which affects the life of the mold;
        ④ The mold is not installed carefully, the method is wrong;

        ⑤ The material of the mold is general. In short, the deformed mold can no longer be used reluctantly, especially for the machine tool. Don't lose it because of the small one.
