Bending (Bending) - metal sheet in the bending machine on the mold or under the pressure of the mold, first after elastic deformation, and then into plastic deformation, in the beginning of the plastic bending stage, the sheet is free to bend - with the upper or lower mold pressure on the sheet, the sheet and the lower mold V groove surface gradually tight, while the radius of curvature and the bending arm of the force is gradually becoming smaller, and continue to press until the end of the trip, so that the upper and lower molds and sheet material at three points of tight contact, at this time, the completion of a V-bending, which is commonly referred to as the bending.

Working principle:

1, forced force principle: steel in the bending process will produce forced force, this force can make the steel shape changes. By adjusting the force on the steel, you can get the desired bending shape.

2, the principle of metal plasticity: steel has certain plastic properties, can be permanent deformation under the action of external forces, without rupture or fracture. In the bending process, the steel will be forced under the action of force, plastic deformation, so as to realize the shape change.

3. Adjustment to different shapes: The shape of steel bending depends on the desired design of the part or component. By analyzing the shape of the part or component, the bending angle and bending radius can be adjusted according to its size, shape and material and other parameters, in order to obtain the desired bending effect.

4, appropriate heating treatment: steel in the more complex bending work, the need for appropriate heating treatment, in order to make it more flexible and easy to bend. By heating the steel, you can make it easier to plastic deformation, and to avoid cracks or deformation in the bending process and other adverse effects.

In summary, steel bending works by utilizing forced forces and the plastic properties of the metal to achieve the desired shape change through proper adjustment and treatment. This process has a wide range of applications in the manufacture of mechanical parts, components, structural materials and so on.
