Aluminum alloy extrusion plate with adjustable external-corner curved surface
The invention discloses an aluminum alloy extrusion plate with an adjustable external-corner curved surface. The aluminum alloy extrusion plate is characterized by comprising a face plate and at least three wing plates, the face plate and the wing plates are strip-shaped plates, the wing plates and the face plate are consistent in longitudinal direction, the width direction of the wing plates is perpendicular to the back face of the face plate, the wing plates are distributed and connected to the back face of the face plate from the edge of one side to the edge of the other side of the back face of the face plate in the width direction in an equally spaced mode, a main elastic plate and an auxiliary elastic plate which are opposite are respectively connected to the edges, away from the face plate, of the two opposite side faces of the adjacent wing plates, the projection edges of the elastic plates and the auxiliary elastic plates of the wing plates in the width direction are overlapped, the edges of the main elastic plates are located on the outer side, the edges of the auxiliary elastic plates are located on the inner side, separation distances are kept between the edges of the main elastic plates and the edges of the auxiliary elastic plates, and at least five steps of arranged clamping grooves are formed in the outer side face, close to the edge, of each main elastic plate. A required extrusion pressure is smaller, and a curved-surface external corner with variable change curvature can be adjusted.
