Cold-bending production technology integrated with spraying treatment and cold-bending production line integrated with spraying unit

The invention provides an online cold-bending production technology integrated with spraying treatment. Cold-state plates and strips are subjected to forming treatment to form cold-bent components having specified shapes, and spraying treatment is performed before or after forming of the cold-bent components. The invention further provides a continuous cold-bending production line integrated witha spraying unit. The production line comprises a forming unit and the spraying unit; the spraying unit is integrated before or behind the forming unit according to the production procedure. By the aidof the production technology and the production line, feeding and discharging links before spraying treatment are omitted, so that the requirements for hoisting equipment and stockpiling warehouse areas in the production process are reduced, the workloads of inventory keepers and crane operators are also reduced, the manpower and material resource costs are reduced substantially, and the production efficiency and the prod
