What Is Bending and Its Parameters

Bending generally refers to sheet metal or sheet metal. Under the pressure of some machines and equipment such as a bending machine, that is, through the pressure of the upper or lower die, first elastic deformation, then plastic deformation The process of making the sheet material bend into shape is called bending.

During the bending process, the material on the inner side of the bending angle is compressed, and the material on the outer side is stretched. The material that can maintain the original length is distributed in a circular arc, so there is a material mechanics The term sex line generally does not exceed one-half of the thickness of the sheet geometry. The bending coefficient is generally expressed by K, which is a calculation coefficient for the position of the neutral line of the material, and it is also very important.
