Abstract

The invention relates to the technical field of an aluminum alloy workpiece manufacturing and discloses a casting-forging forming process for a deformed aluminum alloy workpiece. The casting-forging forming process for the deformed aluminum alloy workpiece comprises the following steps: a, closing a mold, wherein liquid deformed aluminum alloy is injected into a mold cavity; b, carrying out first-time natural cooling on the deformed aluminum alloy in the mold cavity, wherein first-time extrusion forming is carried out by a press machine, and a rough workpiece blank is formed; c, carrying out second-time natural cooling on the deformed aluminum alloy in the mold cavity, wherein a heating mechanism in a mold carries out heating; d, carrying out third-time natural cooling on the deformed aluminum alloy in the mold cavity, wherein second-time extrusion forming is carried out by the press machine, and the deformed aluminum alloy workpiece is formed; and e, carrying out natural cooling on the deformed aluminum alloy workpiece, wherein an upper mold and a lower mold are separated, and the deformed aluminum alloy workpiece is taken out. According to the casting-forging forming process for the deformed aluminum alloy workpiece, the complete deformed aluminum alloy workpiece meeting the requirement of the mechanical property can be directly manufactured, the link of semi-finished products is omitted, the link of subsequent machining is omitted, the manufacturing efficiency of the product of the deformed aluminum alloy is greatly improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of manufacturing aluminum alloy workpieces, in particular to a casting and forging forming process for deformed aluminum alloy workpieces. Background technique [0002] Aluminum alloys can be divided into cast aluminum alloys and deformed aluminum alloys according to different processing methods. Cast aluminum alloys can be formed by casting. Precision workpieces are generally not molded by casting aluminum alloys, and the silicon content in cast aluminum alloys is higher than that in deformed aluminum alloys. Cast aluminum alloys are brittle, so the strength and recovery of cast aluminum alloys are relatively high. Poor, the advantage of cast aluminum alloy lies in direct casting and low molding cost; the mechanical properties of deformed aluminum alloy are better than cast aluminum alloy, but deformed aluminum alloy needs to be processed by melting, pouring, ingot forming, extrusion, forging, etc. process...
