Abstract

The invention discloses a vertical spraying solid-solution quenching machine train for high-strength aluminium alloy sheets. The vertical spraying solid-solution quenching machine train comprises a charge platform, a discharge platform and a solid-solution heating furnace body, wherein the charge platform and the discharge platform are arranged at the two sides of the solid-solution heating furnace body respectively; an air knife, a spraying quenching device and an air-drying system are sequentially installed between the solid-solution heating furnace body and the discharge platform; the charge platform, the discharge platform, the solid-solution heating furnace body, the spraying quenching device and the air-drying system are provided with a transmission rail platform on the same horizontal plane; special fixtures are movably distributed on the transmission rail platform; and the special fixtures clamp the quenched plate materials by vertical clamping structures. The equipment disclosed by the invention is relatively simple, high in production efficiency, low in production cost, capable of producing the high-strength aluminium alloy sheets and medium plates with thicknesses of less than 12mm with high quality, and applicable to the thickness range from 0.5mm to 12mm, of the plate materials.

Description

technical field [0001] The invention relates to the field of non-ferrous metal processing heat treatment equipment, in particular to a vertical spray solid solution quenching machine train for high-strength aluminum alloy thin plates. Background technique [0002] The three typical high-strength aluminum alloys of 2XXX series, 6XXX series, and 7XXX series are heat-treatable and strengthened aluminum alloys, which must be solution quenched to achieve their due high performance. For their plates, when the thickness of the plate is greater than 4mm, it is defined as a medium-heavy plate, and the medium-heavy plate can usually be solution quenched by two methods of immersion and horizontal roller hearth furnaces. In terms of the mechanical properties, internal stress and shape control of the sheet metal after heat treatment, immersion quenching cannot reach the quality produced by the horizontal roller hearth furnace. Therefore, high-performance plates must be produced by solid...
