Problems solved by technology

However, the existing base support plates are often made of metal materials. Although the cast iron support plates have high strength, they are heavy and have poor flexibility. Poor, able to withstand less stress; although the swivel support plate made of aluminum alloy is low in quality and high in flexibility, its strength and toughness are poor, and it is even more difficult to withstand large stress

Abstract

The invention provides a turn seat supporting plate which is made of aluminum alloy. The aluminum alloy comprises the following ingredients in mass percent: 5.0-6.5% of Si, 0.5-0.7% of Mn, 0.17-0.35%of Mg, 1.3-1.5% of Fe, 0.5-0.75% of Ni, 0.3-0.5% of Cu, 0.4-0.5% of nanometer VC, 2.8-7.9% of Ti3N4 and the balance of Al and inescapable impurities. The turn seat supporting plate has the beneficialeffects of good mechanical property, light mass, high flexibility and stable performance.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a swivel support plate and a preparation method thereof. Background technique [0002] In the prior art, the swivel seat of the body is used to fix the body so that it does not shake during use, so as to fix and improve the safety performance of the body. However, in the existing body swivel seat, in order to improve the stability of the swivel seat, the volume of the swivel seat is designed to be relatively large, so that a large space needs to be provided to accommodate the swivel seat, which makes the whole body bulky and inflexible , the installation is also more inconvenient. The swivel support plate bears the weight of the entire body and various stresses generated during body movement and vibration, so it needs to have higher mechanical properties and better load-bearing performance. However, the existing base support plates are often made of metal materials. Although th...
