Abstract

The invention belongs to the technical field of machining and manufacturing, and discloses a manufacturing method for an ultra-long thin-wall aluminum alloy sandwich grid rib double-skin integral tailfin. The manufacturing method includes the steps that a ZL205AA high-strength aluminum alloy is used for pouring and molding the integral tail fin; heat treatment is carried out on the integral tailfin; and numerical control machining is carried out on the integral tail fin after heat treatment. According to the manufacturing method for the ultra-long thin-wall aluminum alloy sandwich grid rib double-skin integral tail fin, the overall quality of precision molding, machining and manufacturing can be improved, and the manufacturing cycle is shortened while the manufacturing cost is lowered.

Description

technical field [0001] The invention relates to the technical field of mechanical processing and manufacturing, in particular to a method for manufacturing an ultra-long thin-walled aluminum alloy sandwich grid rib double-skin integral empennage. Background technique [0002] Sandwich grid rib double-skin integral empennage is an important structural casting. The length specifications of this type of casting are mostly large and super long, and have high requirements for rigidity and processing precision. [0003] In the prior art, the precision casting molding method of the super-long thin-walled aluminum alloy sandwich grid rib double-skin integral empennage is not perfect, and the quality stability of the produced structural casting is poor. Therefore, it is necessary to improve the existing technology and design a precision casting molding method for an ultra-long thin-walled aluminum alloy sandwich grid rib double-skin integral tail that can make the quality and precisi...
