The invention discloses a three-dimensional curved surface roll forming method, which belongs to the field of mechanical engineering. The invention aims to solve the problems of low processing precision and work efficiency of the three-dimensional plate in the prior art. The roller body of the first rolling mechanism and the roller body of the second rolling mechanism of the present invention are both hollow cavity structures, and the deformation liquid is injected into the roller body of the first rolling mechanism and the roller body of the second rolling mechanism. ; Use the corresponding curvature calibration ruler to calibrate the radius of curvature of the roller body of the first rolling mechanism and the radius of curvature of the roller body of the second rolling mechanism, until the radius of curvature of the roller body of the first rolling mechanism and the second rolling mechanism The curvature radius of the roller body of the mechanism meets the required requirements respectively; the sheet to be formed is placed in the forming area, and the first rolling mechanism and the second rolling mechanism rotate and roll the sheet to be formed to complete the roll of the sheet to be formed. Press forming. The invention effectively improves the processing precision and work efficiency of the three-dimensional plate.
Description
technical field [0001] The invention relates to the field of mechanical engineering, in particular to a three-dimensional curved surface roll forming method. Background technique [0002] Sheet forming technology is widely used in aerospace, automotive, electronics and other manufacturing fields, and occupies an important position in the manufacturing industry. At present, the plate-like three-dimensional curved surface parts are mainly obtained by pressure forming with molds. For large-sized plate-like three-dimensional curved surface parts, it is difficult to manufacture the molds, and the corresponding pressure forming equipment and auxiliary devices are expensive. In the face of the above situation, most of the large-size plate 3D curved parts mainly rely on manual forming, which not only fails to meet the product requirements of high precision and high forming quality, but also the production efficiency of the workpiece is low, which requires a lot of time and money. H...
