An optimization method for aluminum alloy forging blanks in hot forging state

Abstract

The invention belongs to the field of aluminum alloy forging blanks in hot forging state. A method for optimizing an aluminum alloy forging blank in a hot forging state is provided, including: machining a square head process boss 10 on a head structure 1 of the blank, and the thickness of the head process boss 10 is less than 150 mm; The upper and lower surfaces of the triangular frame portion 2 are machined with a thickness-reducing groove, and the depth of the thickness-reducing groove is controlled within the minimum size of the blank containing the part, and the minimum distance from any point inside the blank to at least one surface of the blank is less than 150mm; The part of the tail part 3 close to the triangular frame part 2 is machined with a thickening groove, the depth of the thickening groove is controlled within the minimum size of the blank containing the part, and the minimum distance from any point inside the blank to at least one surface of the blank is less than 150mm; The part of the tail part 3 of the blank away from the triangular frame part 2 is processed into a square tail process boss 9 , the tail process boss 9 is larger than the head process boss 10 and the thickness is less than 150mm.

Description

technical field [0001] The invention belongs to the field of aluminum alloy forging blanks in a hot forging state. Background technique [0002] For aluminum alloy forging blanks supplied in a hot forging state, the minimum thickness of the original blank is 180mm, which is greater than the maximum heat treatment limit size of 150mm stipulated by the national military standard. Therefore, it is necessary to add rough machining, heat treatment and physical and chemical testing to the machining process. Forgings need to be turned back and forth between workshops during the production process, which increases the production cycle of parts and brings inconvenience to production. Contents of the invention [0003] The object of the present invention is to provide an optimization method for aluminum alloy forging blanks in a hot forging state, so that the blanks can not only meet the machining requirements of parts, but also meet the maximum limit size requirements of heat treat...
