Alloy nut connecting piece low in weight and high in strength and preparation method thereof

Abstract

The invention discloses an alloy nut connecting piece low in weight and high in strength. The alloy steel nut connecting piece is characterized by being prepared from, by weight percent, 0.26%-0.34% of carbon, 0.17%-0.25% of manganese, 0.05%-0.14% of niobium, 2.15%-3.25% of aluminum, 0.03%-0.05% of molybdenum, 2.4%-2.7% of magnesium, 0.073%-0.14% of nickel, 0.032%-0.045% of tungsten, 0.07%-0.08% of tin, 20%-25% of a refining slag regulating agent, a proper amount of nitrogen and the balance Fe and inevitable impurities; and the refining slag regulating agent is prepared from, by weight, 20-45 parts of bauxite, 15-25 parts of marble, 19-44 parts of silica sand, 5-10 parts of barium, 10-11 parts of active lime, 9-10 parts of fluorgypsum, 4-8 parts of silica powder, 6-7 parts of electric smelting magnesium powder, 5-10 parts of albite and 2-5 parts of an aluminum shot. The alloy nut connecting piece is low in weight and high in strength, and dephosphorization is thorough; and a pattern is sprayed to the surface of a nut, and therefore the attractiveness of the nut is improved while rust prevention is achieved.

Description

technical field [0001] The invention relates to the field of mechanical parts processing, in particular to an alloy nut connector with light weight and high strength and a preparation method thereof. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. A component that must be used in all manufacturing machinery is divided into carbon steel, stainless steel, and non-ferrous metals (such as copper) according to different materials. several types. For example: self-locking nuts, anti-loosening nuts, lock nuts, four-claw nuts, nuts, nuts, screw-in nuts, safety nuts, thin rod screw connection nuts, self-locking hexagon cap nuts, nuts for special anchor screws, hexagonal crown nuts Thin nuts, eye nuts. The main operation method of the embedded knurled copper nut is injection molding. After heating, it is embedded into the plastic part or directly molded. If mold injection is used, the melting point of PA / NYLOY / PET i...

Problems solved by technology

The molten steel treated with the refining and slagging agent contains very low sulfur, oxygen and inclusions, but the refining and slagging agent in the document has few types of ingredients, and the preparation method is simple, so it is difficult to achieve the desired effect, and the method is single, and It does not point out the scheme of combining with other processing methods, nor does it point out the complete supporting technical scheme of its subsequent mechanical casting and processing technology. This paper combines the existing technology to give a complete processing technology to improve the overall mechanical properties of nuts.
