Continuous forming device for metal composite thick plate three-dimensional curved surface

Abstract

The invention provides a continuous forming device for a metal composite thick plate three-dimensional curved surface. The forming problem of the metal composite thick plate three-dimensional curved surface is solved. A plurality of rollers with the heights being adjustable which are arranged in the axial direction are adopted to form roller sets. One upper roller set and two lower roller sets serve as forming tools of a metal composite plate material. Vertically bending deformation of a contact area plate material is obtained through three-point bending of the upper roller set and the lower roller sets, and the heights of the rollers in the roller sets are changed to form a roller set curve outer contour to obtain horizontal bending deformation of the contact area plate material. By means of a pushing mechanism and a pulling mechanism, continuous feeding of the plate material is achieved, and therefore, the double-curvature metal composite thick plate three-dimensional curved surface is continuously formed. The continuous forming device is simple in structure, low in construction cost and good in flexibility. A curved surface is formed through two-way bending, a mould is not needed, and no-mould forming of different shapes of curved parts can be conducted on one piece of equipment. Due to the adoption of the mode of continuous forming, the continuous forming device is applicable to curved surface machining of a large-scale composite plate.
