Abstract

The invention relates to a mold-pressing device, in particular to a mold-pressing device for an aluminium alloy grid rod piece and a necking molding method of the device, and belongs to a spatial multi-layer aluminium alloy grid. The device comprises a reference pressing mold, two driven pressing molds and a baffle, wherein a baffle fixing hole is formed in the outer wall of the reference pressing mold; the baffle is positioned to the reference pressing mold by the aid of the baffle fixing hole; circular bodies distributed at an interval are defined by the reference pressing mold and the two driven pressing molds; tube cavities are formed in the circular bodies; and two ends of the baffle are connected with the driven pressing molds respectively in a contact manner. According to the mold-pressing device for the aluminium alloy grid rod piece and the necking molding method of the device, the structure is compact, and the connecting and bearing capacity is improved.

Description

technical field [0001] The invention relates to a molding device, in particular to a molding device of an aluminum alloy network frame bar and a shrinking tube forming method thereof, belonging to a space multilayer aluminum alloy network frame. Background technique [0002] Aluminum alloy material has the characteristics of formability, good machinability, light structure weight, high structural strength (not much different from Q235 carbon steel strength), strong earthquake resistance, etc., and is an excellent building structural material. However, the weldability of aluminum alloy is extremely poor, and it cannot be directly welded to the steel grid rod and the sealing plate. Contents of the invention [0003] The present invention mainly solves the deficiencies in the prior art, and provides an aluminum alloy network frame with a compact structure, which can realize the effective connection between aluminum alloy rods and sealing plate nodes, and the strength of the n...
