Aluminum alloy extrusion plate with adjustable external-corner curved surface

Abstract

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.

[0002] China is a big industrial country. With the advancement of science and technology, China's manufacturing industry is booming, the economy is becoming stronger and stronger, and new technologies and materials are constantly emerging. Among them, aluminum alloy, which has excellent mechanical and chemical properties, is widely used in various industries. For example, aluminum profiles are often used in environmental decoration, but they are mainly used for the construction of frame structures. They are light in weight, convenient in connection, and have outstanding texture and decorative effects. There are more applications in this area, and less applications in other areas. If a certain radian surface is required for decoration at some columns or corners, there is no suitable product, and some are only some fixed-sized male corners, which cannot meet more diverse requirements on site; there are also existing aluminum alloys Profiles are mostly produced through the extrusion process. When producing extrusion-molded hollow tubular products, the aluminum alloy billet first enters multiple flow channels to reach the extrusion port, and then merges and merges into one and is extruded from the extrusion port. The aluminum alloy billet enters multiple channels. Separation into multiple channels in the process of a flow channel increases the resistance invisibly, and requires higher extrusion pressure to form. When the multi-channel aluminum alloy billets are combined, they are prone to wrinkles or cracks due to the stability of the process conditions. These still need to be solved technically.
