Embodiment Construction

[0013] The present invention will be described in further detail below with reference to the examples. The following examples are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0014] A processing method of lattice truss structure, the method includes the following steps:

[0015] a) Blanking: choose aluminum alloy plate, cut into a certain size according to the requirements, divided into upper panel material, lower panel material, and core material;

[0016] b) Stamping and forming: The cut core material is placed on a punching machine for punching, and processed into a thin plate with diamond-shaped holes, and then the holed thin plate is placed in the punching slot, and the core is formed by punching;

[0017] c) Assembly: Place the upper panel with solder side facing down, and the lower panel with solder side facing up. The upper panel, core body, and lower panel are superimposed from top to bottom to form a latt...

Abstract

The invention discloses a processing method of a lattice truss structure. The method includes the steps: a) performing blanking, to be specific, subjecting aluminum alloy plates to cutting to required sizes to form upper panel material, lower panel material and core material; b) performing punch forming, to be specific, placing the cut core material on a punch press to punch and form a sheet with rhombic holes, and placing the perforated sheet into a stamping channel to obtain a core by punch forming; c) performing assembling, to be specific, with a solder face of the upper panel material facing down, and a solder face of the lower panel material facing up, overlaying sequentially the upper panel, the core and the lower panel to form the lattice truss structure; d) performing welding, to be specific, performing seamless welding of the assembled lattice truss structure to allow the upper panel, the core and the lower panel to be fixedly bound together; and e) performing spraying, to be specific, performing spraying treatment on the surface of the welded lattice truss structure. The truss produced by the processing method has the advantages of being firm and safe, and smooth and attractive in appearance, and having good performances of impact resistance, vibration resistance, heat insulation and sound insulation.

Description

Technical field [0001] The invention relates to the field of architecture, in particular to a processing method of a lattice truss structure. Background technique [0002] Traditional sandwich panels are mostly solid panels and have a large weight. The lattice truss structure is used in aerospace and satellite structures because of its light weight and high strength. The research mainly focuses on the topological characteristics of lattice materials, manufacturing process, elastic mechanical behavior, and multifunctional development of structures. Due to its low density, low price, and good forming performance, aluminum alloy is often used as one of the main materials selected by researchers. Summary of the invention [0003] The invention provides a processing method for a lattice truss structure, which makes the original lightweight lattice structure higher in strength, stronger and safer, smooth and beautiful in appearance, and has good impact resistance, vibration resistance...
