Chinese invention patent (CN107739920A) discloses a light aluminum alloy material suitable for small-sized special-shaped parts and its processing method. Although the aluminum alloy products prepared by powder metallurgy have good wear resistance, the preparation process is complicated and the cycle is relatively short. long, it is difficult to achieve industrial production
Chinese invention patent (CN107739923A) discloses an Al-Mg-Si alloy with good usability, easy coating, and good processability. The alloy raw materials can be fully fused through the stage feeding method in the preparation process, which helps to improve the quality of the alloy. The plasticity and deformability of the material, but the mechanical strength, hardness and density of the obtained alloy are not ideal because the billet is not heat-treated

Abstract

The invention relates to a high-hardness aluminum-made projection lamp support and a processing method thereof and belongs to the technical field of lighting electrical appliance part process. The projection lamp support is prepared by melting the following raw material ingredients in mass percent: 0.02 to 0.08% of manganese powder, 0.2 to 0.8% of silicon powder, 0.025 to 0.08% of titanium powder,0.1 to 0.3% of cobalt powder, 0.05 to 0.20% of beryllium powder, 0.08 to 0.25% of potassium fluoborate and the balance of aluminum powder and unavoidable impurities. In a processing process, alloy liquid is purified by adding a covering agent, and hardness and corrosion resistance of alloy are improved by effective thermal treatment and degreasing electroplating.

Description

technical field [0001] The invention relates to a high-hardness aluminum floodlight bracket and a processing method thereof, belonging to the technical field of processing lighting electrical components. Background technique [0002] Floodlights, also known as spotlights, are lamps that specify that the illuminance on the illuminated surface is higher than that of the surrounding environment. Generally, it can be aimed at any direction and has structures that are not affected by climatic conditions. It is mainly used for large-area worksites, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. [0003] The floodlight bracket is used as the supporting part of the lamp body. The common brackets are short, long, straight, and curved. Different models can be selected according to different requirements. The main consideration of the floodlight bracket is whether the load capacity meets the requirements, and then the installation location. For some sp...
