A 5G antenna fixing base and forming method thereof

Abstract

The invention discloses a forming method of a 5G antenna fixing seat. The forming method comprises the following steps of designing a forming mold; proportioning raw materials, wherein the raw material comprises, in percentage by mass, 0.4%-1.5% of carbon powder, 1%-4% of copper powder, 1%-5% of nickel powder, 0.25%-2% of molybdenum powder, 0.8%-6% of chromium powder, 1%-5% of manganese powder, 2%-6% of carbon fibers and the balance iron powder; uniformly mixing to obtain mixed powder; pressing to obtain a green body; sintering to obtain a sintered part; performing carbonitriding on the sintered part, performing low-temperature tempering and heat preservation after quenching and heat preservation is performed, and performing cooling to obtain the 5G antenna fixing seat. The invention further discloses the 5G antenna fixing seat. According to the 5G antenna fixing seat and the forming method thereof, a traditional powder system is optimized through adding the chromium powder, the manganese powder, the carbon fibers and the like, cooperation of the raw materials with different particle sizes and different proportions is controlled, the binding performance among the raw materials is enhanced so that the raw materials can be evenly distributed, the phenomena of cracking, agglomeration and the like after pressing and sintering are avoided, and therefore the obtained product has goodhardness, density, strength and wear resistance.

Problems solved by technology

[0002] At present, most of the traditional molding process of antenna fixing base adopts the combination of lathe and CNC equipment, and then the surface treatment process of the product. The processing quality is easily affected by operator factors, and the processing contour of the product is limited by the tool, so it is impossible to cut and shape the internal structure of the product with complex structure, the processing efficiency is slow, and the production cost is high

With the development of industrial technology, the current production of antenna holders with complex structures is more inclined to use powder metallurgy processing molding technology, which mainly uses C-Cu-Ni-Mo powder system, this system only uses metal materials, mechanical properties and The coefficient of friction is unstable, which fails to meet the production requirements of high strength, high density and wear resistance, and simple mechanical mixing is not enough to make the metal materials evenly mixed, and it is easy to crack due to uneven distribution of metal materials during the sintering process, etc. Phenomenon, thus affecting the overall performance of the product
