Description

technical field [0001] The invention relates to the technical field of aluminum alloy sheet production, in particular to a forging device for producing aluminum alloy sheets. Background technique [0002] An alloy based on aluminum with a certain amount of other alloying elements added to enhance the corrosion resistance of the alloy sheet and improve surface smoothness and toughness. Among them, in the existing equipment for forging thin aluminum alloy sheets, during the forging process, when the forging template is pressed against the aluminum alloy sheet on the fixed template, the aluminum alloy sheet is mainly subject to longitudinal pressure and transverse tension. As a result, the aluminum alloy sheet surface outside the forging end face is slightly bent with the forging edge surface as the supporting point, causing the aluminum alloy sheet to shrink or extend outward, resulting in deviation of the forging lines or hole positions on the aluminum alloy sheet. After the...

Problems solved by technology

Among them, in the existing equipment for forging thin aluminum alloy sheets, during the forging process, when the forging template is pressed against the aluminum alloy sheet on the fixed template, the aluminum alloy sheet is mainly subject to longitudinal pressure and transverse tension. As a result, the aluminum alloy sheet surface outside the forging end face is slightly bent with the forging edge surface as the supporting point, causing the aluminum alloy sheet to shrink or extend outward, resulting in deviation of the forging lines or hole positions on the aluminum alloy sheet. After the forging template and the fixed template are forged and separated from each other, the surface of the aluminum alloy sheet outside the forging face will be tilted or the curved surface will be tilted, especially the thin aluminum alloy sheet, which is more likely to be deformed after separation. For some thinner aluminum alloy sheets, after the forging is completed, the template or forging template is fixed by adsorption, which makes it inconvenient to take out the aluminum alloy sheet after forging and pressing, which affects the processing efficiency.
