Alloy for precision machining jig and preparation method thereof

Abstract

The invention discloses alloy for a precise machining clamp and a preparation method for the alloy. The clamp comprises the following raw materials of, by mass, 1.5%-2.3% of beryllium powder, 1.9%-2.7% of zirconium powder, 5.3%-6.1% of calcium, 3.0%-3.8% of molybdenum powder, 0.8%-1.5% of vanadium powder, 0.3%-0.7% of tin powder, 7.2%-8% of copper powder, and the balance aluminum powder. According to the alloy for the precise machining clamp and the preparation method for the alloy, the alloy obtained after the beryllium powder, zirconium powder, calcium, molybdenum powder, vanadium powder, tin powder, copper powder and aluminum powder are subjected to smelting, rapid hardening, hydrogen decrepitation, cold press molding and segmental calcination under the action of scientific cooperation of the component contents is uniform in structure, has high hardness, high breaking tenacity and corrosion resistance, can be applied to the precise machining clamp, and can further eliminate residual stress of a high-temperature part when being matched with the high-temperature part, and the usage reliability and the size precision of the part are ensured. The alloy for the precise machining clamp and the preparation method for the alloy have the advantages that service life is long, high production efficiency is high, the size precision of the machined part is high, the part product quality and yield are improved, pollution to the environment is avoided, and the alloy and the preparation method are suitable for industrial production.

Description

Technical field

[0001] The invention relates to the technical field of alloy materials, in particular to an alloy for precision machining fixtures and a preparation method thereof. Background technique

[0002] Fixture is a device used to fix the processing object during the mechanical manufacturing process so that it occupies the correct position to accept construction or inspection. Broadly speaking, in any process in the process, a device used to quickly, conveniently and safely install a workpiece can be called a fixture. For example, welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements of the size, geometry, and mutual position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and cla...
