Abstract

The invention discloses a molding tool of an aluminum profile three-dimensional bent beam and a process; and the molding tool is high in automation degree, relieves the working intensity of operators,and improves the product quality and the production efficiency. The molding tool comprises a tool mounting platform, a concave mold fixed on the tool mounting platform, a convex mold movably connected to the tool mounting platform, and two sets of stretching modules symmetrically arranged at the two ends of the tool through a stretching module mounting table; the two sets of stretching modules are respectively fixed at the two ends of workpieces; and the stretching modules apply stretching force and torsion force on the workpieces. The molding tool of the aluminum profile three-dimensional bent beam and the process realize automatic production of asymmetric three-dimensional molding of longer aluminum profiles, greatly relieve the working intensity of finishing and profiling by the operators, and improve the production efficiency and the product quality.

Description

technical field [0001] The invention relates to the technical field of EMU streamlined workpiece processing, in particular to a molding tool and a molding process for a long asymmetrical three-dimensional aluminum profile curved beam at the top of the EMU streamlined head. Background technique [0002] In recent years, with the development of the rail vehicle industry, the requirements for the shape design of passenger cars and the lightweight of the whole vehicle have been continuously improved. Due to the characteristics of light weight and easy forming, aluminum profiles are widely used in the body structure of rail passenger cars such as high-speed EMUs, and the streamlined front of high-speed EMUs also requires the forming and welding of large and long three-dimensional aluminum profiles. Therefore, aluminum profiles The three-dimensional molding process has also become the research direction of this industry. [0003] Among the parts composed of streamlined fronts, th...
