The invention discloses an upsetting method for an aluminum alloy blank with an ultra-limit height-diameter ratio. The upsetting method comprises the steps that a homogenized blank with the ultra-limit height-diameter ratio is selected; heating the blank to a first preset temperature and keeping the temperature for a first preset time; the blank is moved to a flat anvil, the inclination angle between the blank and the flat anvil ranges from 5 degrees to 30 degrees for forging and pressing, the forging and pressing deformation ranges from 10% to 20%, the blank is subjected to forging and pressing in the reverse direction with the same amount after being aligned, two-side forging and pressing are completed, then the blank is rotated by 90 degrees around the axis of the blank, the forging and pressing deformation ranges from 10% to 20%, the blank is subjected to forging and pressing in the reverse direction with the same amount after being aligned, and four-side forging and pressing are completed; the blank subjected to four-side forging and pressing is vertically placed on a flat anvil to be subjected to small-deformation forging and pressing, and the forging and pressing deformation ranges from 5% to 20%; four-side forging and pressing and small-deformation forging and pressing are repeated until the height-diameter ratio of the blank reaches a preset value, then large-deformation forging and pressing are conducted, and the forging and pressing deformation is 50%-70%. Compared with the prior art, the upsetting quality of the aluminum alloy blank with the ultra-limit height-diameter ratio can be guaranteed, and resource waste is avoided.
Description
technical field [0001] The present application relates to the technical field of aluminum alloy forging, and more specifically, relates to an upsetting method for an aluminum alloy billet with an ultra-limit aspect ratio. Background technique [0002] Large aluminum alloy components have been widely used in aerospace, rail transit, civil vehicles, special equipment and other fields. [0003] In recent years, with the continuous development of the forging industry at home and abroad, the aluminum alloy components have a large-scale and integrated design trend. With the continuous exploration of space by humans, the structure of new carrier equipment in various countries in the world is developing towards a large-scale direction. The aluminum alloy components The specification requirements are getting bigger and bigger, and the performance requirements are getting higher and higher. Aluminum alloy components forged with the height-to-diameter ratio (2.5 to 3) of traditional a...
