| Abstract: |
| The work aims to improve the roll forming quality in order to provide test basis for the industrialization of laser composite textured roll. The roll forming process was simulated by the numerical simulation method to obtain the forming stress-strain and radial thickness of sheet at different friction coefficient combinations and the optimum mold surface texture to provide basis for treatment of roll texture. According to the results of numerical simulation, laser surface texturing was adopted to treat the roller surface, the forming contrast experiment was carried out for laser texturing mold and non-laser texturing mold and the residual stress, strain and edge thinning rate of the forming part were detected and analyzed. From the results of numerical simulation, the edge area of lower roll should be anti-friction area and the edge area of upper roll should be friction-added area. Laser microtexture anti-friction was conducted to the lower roll edge area and laser texturing friction addition was carried out to the upper roll edge area. Through the results of forming test, the test results were basically consistent with the numerical simulation results. Compared to the non-textured mould, the laser surface texturing roll mould could optimize the distribution of molding stress and strain, reduce the thinning rate of the plate thickness by 5.06% and improve the uniformity of the forming part improved by 3.9%. Therefore, the edge area of the forming part was accumulated with residual stress and strain. Compared with the non-textured mould, the laser composite textured roll can obviously improve the edge stability and forming quality of the forming part. |
