Golden Dragon's CNC bending arc machine

The working principle of the bending machine The CNC bending machine manufactured by Jinan Jinlong Machinery Co., Ltd. has a powerful pull-bend function, a special technical structure, and has its own independent technology integrated therein. Therefore, the sales volume has been particularly good. Now let's introduce how we work under the following bending machine produced by Jinlong: The essence of the strip shape defect is that the strip has different internal stress in the width direction, making it along the same width as the width Fibers produce a small difference in length between the lengths. In order to obtain plate-shaped flat strips, it is only necessary to apply a stress exceeding the yield limit to the length of the strip, so that the length and the length of the fibers simultaneously produce a certain degree of plastic deformation. After the stress is relaxed, the extended and long fibers remain, so that the strip The length and internal stress of the longitudinal fibers in the material tend to be the same, and the direction is the same, achieving the purpose of leveling. The bending machine is based on the elastoplastic elongation theory of the material to straighten the strip. The basic principle of the numerical control arc bending machine is that the strips to be leveled are alternately arranged one above the other under the tension applied by the tension roller group. A plurality of sets of small-diameter bending rolls, under the combined action of stretching and bending, produce a plastic elongation along the length direction so that the length of each longitudinal fiber of the strip tends to be uniform, and the straightness of the strip is improved.
