Embodiment Construction

[0014] The isothermal precision forging process of aluminum alloy materials, according to the material requirements of special-shaped aluminum alloy parts, selects aluminum alloy ingots of different grades, and goes through forging billets, isothermal pre-forging with molds, isothermal precision forging and heat treatment to maintain the material. Sufficient plasticity, using precision forging dies, direct forging and forming, to achieve the purpose of one-time molding of special-shaped parts, and through the rearrangement and refinement of its internal lattice, the density and tensile strength of the internal structure of the part are greatly enhanced, suitable for precision optics High-strength components supporting the device. Its specific method steps are as follows:

[0015] a) Forging billet: according to the design material requirements of the part, select the corresponding brand, specification and material used to make the part to intercept the ingot. After heating at ...

Abstract

The invention relates to a constant temperature fine-forging technique process used for the aluminum alloy parts with different shapes. The invention is mainly characterized in that constant temperature blank forging, die pre-forging, corrode-washing, fine forging of dies, heat treatment and re-corrode washing, etc. processes are adopted under a given temperature to enlarge the internal density of the parts and optimize the fiber direction and distribution of the inner construction of the parts, so as to enhance the strength and improve the appearance quality of the parts. The invention can enhance machining efficiency, reduce machining cost and conserve precious materials. The invention can enhance the compound capability of the materials of parts.

Description

technical field [0001] The invention belongs to the technical field of forging processing, and relates to an isothermal precision forging process for aluminum alloy special-shaped parts. Background technique [0002] In the known technology, aluminum alloy special-shaped parts in precision optical devices not only have certain precision requirements for their complex shapes, but also have particularly strict requirements for the internal structure and strength of their materials. At present, in the processing of these parts, the commonly used process method is: according to the grade requirements of the part material, the bar is used for machining. Due to its complex shape, wire cutting, electric pulse, CNC machine tools, machining centers, Fitters and other processing equipment for processing. The processed parts are rough in appearance, low in strength, and labor-intensive, with many processes, low efficiency and high cost, resulting in a great waste of precious materials...
