CNC bending stainless steel pipe bending machine
There are many models of pipe bending machines. Various models of automatic pipe bending machines can bend stainless steel pipes. In addition to stainless steel pipes, it can also bend steel pipes, carbon steel pipes, copper aluminum, profiles, etc. These metal materials also belong to stainless steel pipes, which are difficult to bend because stainless steel pipes are harder and harder to plastic than carbon steel pipes. Therefore, during the bending process, the inner arc of stainless steel pipes is prone to wrinkling. Especially curved thin-walled stainless steel pipes are more severe.
22 * 2 * 0.4 thin-walled stainless steel square tube bends, in which case the bent product cannot be considered qualified. To solve the problem of wrinkling in stainless steel pipe bending machines, CNC pipe bending machines can only add cores inside the pipes. Bending thin-walled stainless steel pipes even requires adding three active joints to prevent excessive deformation during the bending process, making the outer arc of the bend very full. A wrinkling mold needs to be added to solve the problem of wrinkling of the inner arc, as the inner arc of stainless steel pipes is squeezed during the bending process. Therefore, the function of the anti wrinkling mold is to prevent the inner arc from being squeezed and wrinkling inward, but to extend back and smoothly transition.
Therefore, bending stainless steel pipe bending machines require an additional set of wrinkle resistant molds compared to products that bend other materials.
