Automobile front top lamp support being high in outer-wall hardness and tensile strength, and preparation method of automobile front top lamp support

Abstract

The invention discloses an automobile front top lamp support being high in outer-wall hardness and tensile strength. The automobile front top lamp support is characterized by comprising the following components in parts by weight: 500-550 parts of limonite, 30-40 parts of maghemite I, 400-480 parts of pyrite, 10-20 parts of cinnabar, 8-9 parts of malachite, 10-14 parts of maghemite II, 5-6 parts of sphalerite, 3-4 parts of azurite, 6-7 parts of chalcocite, 2-3 parts of cassiterite, 3-4 parts of tantalite-columbite, 1-2 parts of jamesonite, 2-3 parts of scheelite, 8-9 parts of ilmenite, 3-4 parts of tantalum rutile, 20-30 parts of niccolite and 200-260 parts of a nickel ore biological metallurgy catalyst. According to the automobile front top lamp support disclosed by the invention, the biological metallurgy technology is adopted and the nickel utilization ratio is improved; meanwhile, the mechanical properties of parts are improved by adopting a multi-channel machining process; and the machined automobile front top lamp support is high in outer-wall hardness and the tensile strength.

Description

technical field [0001] The invention relates to the field of mechanical parts processing, in particular to an automobile headlight bracket with high outer wall hardness and good tensile strength and a preparation method thereof. Background technique [0002] Since the emergence of machinery, there have been corresponding mechanical parts. But as a discipline, mechanical parts are separated from mechanical construction and mechanics. With the development of the machinery industry, the emergence of new design theories and methods, new materials, and new processes, mechanical parts have entered a new stage of development. Theories such as finite element method, fracture mechanics, elastohydrodynamic lubrication, optimization design, reliability design, computer-aided design (CAD), solid modeling (Pro, Ug, Solidworks, etc.), system analysis and design methodology have gradually For research and design of mechanical parts. To better realize the synthesis of multiple discipline...

Problems solved by technology

In this paper, aiming at the mineral characteristics of low-grade nickel laterite ore in different layers in a nickel laterite deposit in a mining area in Southeast Asia, a new hydrometallurgical process was chosen to study the theory and technology of comprehensive extraction of valuable metals such as nickel, cobalt, and iron. The clean and efficient treatment of ore provides a reliable basis, but the paper only gives the nickel extraction process, and does not give perfect guidance for the actual mechanical processing application in the later stage
