Embodiment Construction

[0016] A production method of an aluminum profile frame for a high-speed rail sound barrier uses aluminum rods as the main material, and undergoes mold design, batching, smelting, extrusion, discharging, artificial aging, powder spraying, and assembly molding. Aluminum profile frame, the frame is surrounded by aluminum alloy frame 3, sawed and cut into 45° angle, A is connected with corner code 6; Yuan ethylene propylene rubber 4; C place outer frame is connected with spring leaf 8, to increase strength.

[0017] The production method of the aluminum alloy frame comprises the following steps:

[0018] 1. Mold design: The mold size is 280*185, such a large size can increase the strength of the mold, and it is not easy to collapse; the design uses 7 diversion holes, 6 bridge positions, and a double hole in the middle, which can serve as an intermediate supply Foot, the foreman is not easy to shift and so on. The depth of the welding chamber is 25, which plays the role of weldi...

Abstract

The invention relates to a production method of an aluminum section frame for a high-speed rail sound barrier. With aluminum bars as a main material, the novel aluminum alloy section frame is produced by the steps of mold designing, burdening, smelting, extruding, discharging, manual aging, powder spraying as well as assembling and forming. According to the invention, the aluminum alloy frame adopts a 45-degree design and is waterproof; and the aluminum alloy frame the surface of which is subjected to electrostatic powder spray treatment has no changes, such as aging, falloff, color fading and the like in terms of hydrochloric acid resistance, corrosion resistance, weather resistance, and the like after being subjected to experiments for 1000h; and the service life of an assembly is ensured.

Description

technical field [0001] The invention relates to the field of aluminum profile manufacture, in particular to a design of a porous mold for high-speed rail sound barrier materials and a production method thereof. Background technique [0002] China has built the world's largest railway transportation network, and the operating mileage of high-speed railways has also jumped to the world's largest this year. In March 2010, China's high-speed railways in operation reached 6,552 operating kilometers. Many high-speed railways have to pass through densely populated areas, which will cause noise interference and have a great impact on people's lives and work. Therefore, some sound insulation barriers should be installed next to the high-speed railways. The commonly used noise barriers are made of steel structures and plastic panels. The structure, the sound insulation effect is not ideal, the service life is short, and the installation is inconvenient. Chinese patent specification C...
