Aluminum Alloy Extrusion Sheet Die with Adjustable Surface Angle

Abstract

The invention discloses an aluminum alloy extrusion plate mold with a curved surface internal corner adjusting function. The aluminum alloy extrusion plate mold is characterized by comprising a panel runner and wing plate runners, at least three wing plate runners are arranged, the cross sections of the wing plate runners are perpendicular to that of the panel runner, and the wing plate runners are distributed at equal intervals from one side edge to the other side edge in the width direction of the panel runner and connected to the panel runner. The two opposite sides of the outer half segments, away from a panel, of the adjacent wing plate runners are provided with symmetrically-distributed reverse-tooth runners. Five or more levels of reverse teeth are arranged on the reverse-tooth runner on each side, the opposite reverse teeth between the adjacent wing plate runners are close to each other level by level from outside to inside, and longitudinal groove runners are connected to the longitudinal center line positions, between the adjacent wing plate runners, of the panel runner; expansion block runners are arranged below the opposite reverse tooth runners between the adjacent wing plate runners, buckle runners are arranged on the two sides of the expansion block runners, and the middle portions of the expansion block runners are connected with guide limiting plate runners; and the required extrusion pressure is small, and curved surface internal corners of different curvatures can be adjusted for extrusion products.

[0002] China is a large 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. Aluminum alloy is one of them. It has excellent mechanical and chemical properties and 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.
