Aluminum alloy extruded plate with adjustable internal angle of curved surface

Abstract

The invention discloses an aluminum alloy extrusion board with an adjustable hook face internal angle. The aluminum alloy extrusion board is characterized by comprising a face board and wing boards; the number of the wing boards is at least three, the face board and the wing boards are all long-strip-shaped boards, the longitudinal direction of the wing boards is coincident with the longitudinal direction of the face board, the width direction of the wing boards is perpendicular to the back face of the face board, the wing boards are distributed on and connected to the back face of the face board at equal intervals from the edge of one side to the edge of the other side in the width direction of the back face of the face board, symmetrically-distributed reverse teeth are arranged on the two opposite lateral faces, far away from the outer half section of the face board, of the adjacent wing boards, the opposite reverse teeth between the adjacent wing boards get close step by step from outside to inside, and a longitudinal groove is formed in the longitudinal center line portion, between every two adjacent wing boards, of the back face of the face board; and expansion blocks are arranged between the opposite reverse teeth between the adjacent wing boards, buckles capable of being buckled on barbs on the same sides are arranged on the two sides of the expansion blocks respectively, and guiding limiting plates capable of being inserted into the longitudinal grooves are arranged in the middles of the expansion blocks. The required extrusion pressure is small, and the hook face internal angles with different change curvatures can be obtained through adjustment.

[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 properties 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 inner corners, there is no suitable product, and some are only certain fixed-sized inner corners, which cannot meet more diverse requirements on site; there are also existing aluminum alloy profiles Most of them are 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 The separation of the runners into multiple channels invisibly increases the resistance, 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.
