Embodiment Construction

[0025] Now in conjunction with the magnesium alloy honeycomb panel production process schematic diagram, the present invention is further specifically described:

[0026] (1) Manufacture of honeycomb core structure 1: The magnesium alloy, such as AZ31B, is rolled into a foil with a thickness of 0.08-0.25mm by cold rolling or hot rolling. After heat treatment and surface treatment, its performance parameters are shown in Table 1. ; Cut the above foil material into foil strips with a width of 6-38mm, such as figure 1 shown;

[0027] Then the above-mentioned foil strips are accurately and non-damagingly bent to form a honeycomb core blank, such as figure 2 As shown, the formed excessive fillet radius is 0.45mm, corresponding to it, the forming strain rate is 0.0015 / s;

[0028] Place the formed honeycomb core blank on the working platform for gluing, positioning, and lamination, and then cure it at a specified temperature of 80-120°C and a specified pressure of 3-10MPa to make ...

Abstract

The invention relates to a magnesium alloy cellular plate and a production process thereof, the magnesium alloy cellular plate is formed by an upper panel, a lower panel, and a cellular core construction which are adhered and connected together, and is characterized in that magnesium alloy sheets are rolled to make the upper panel and the lower panel, the cellular core structure is a regular hexagon cellular-shaped structure which is made of magnesium alloy foil material through the processes of rolling, cutting, plastic bending precision molding, and positioning bonding. The magnesium alloy cellular plate has the advantages of high intensity and ultra-light weight, and can be widely used as the parts such as the wall plate, the floor plate, and the partition, etc. in the transportation equipment such as the spacecraft, the aircraft, the light high-speed train, and the urban rain train, etc., and the obvious weight-loss effect is achieved.

Description

technical field [0001] The invention relates to a honeycomb structure composed of metal, in particular to a magnesium alloy honeycomb plate and a production process thereof. Background technique [0002] Honeycomb panel is a high compressive strength, lightweight mechanical and engineering structure, which is bonded by upper and lower panels and honeycomb core. [0003] There are three commonly used honeycomb panels, including paper honeycomb panels, fiberglass honeycomb panels and aluminum honeycomb panels. The honeycomb core of the paper honeycomb panel is made of paper impregnated with resin and glued with plant fiber foam board. It has low cost, low strength, and is not resistant to moisture. Now it is only used in structures such as light mobile houses; FRP honeycomb panel is a kind of Composite honeycomb panels made of glass fiber and resin have the characteristics of light weight and high strength, but the disadvantages are low impact resistance, easy aging and the u...
