Abstract

The invention relates to a production method of a cylindrical and tubular mechanical part. The production method comprises the steps that reduced iron powder is marked as the raw material A, and a mixture of liquid unsaturated polyester resin and a liquid curing agent is marked as the raw material B; the raw material B is poured into the raw material A, stirring and uniform mixing are performed, then mixing and milling are performed, and an obtained mixture is loaded into a steel capsule with the inner wall and outer wall each coated with a layer of a lubricating agent; the steel capsule is subjected to vacuumizing treatment for 5-30 min under the pressure of minus 0.01-minus 0.015 MPa; then the steel capsule is pushed into a die of a metal extrusion press, isostatic cool pressing is performed, and a tubular or cylindrical blank is obtained; and after the obtained blank is subjected to primary curing, cutting and dividing and deep curing, the mechanical part product is obtained. The mechanical part produced through the production method is low in weight, the density is 1.8-3.5 t/m<3> which is 2-4 times smaller than the density of steel, the strength of the mechanical part is not lower and is higher than those of structural steel, duralumin, fir and the like, and the mechanical part can completely replace part of cast blanks.

Description

technical field [0001] The invention relates to a production method of mechanical parts, in particular to a production method of tubular mechanical parts, belonging to the technical field of mechanical processing. Background technique [0002] The traditional casting methods of mechanical parts all use metal (black or non-ferrous) to melt at a high temperature of 800-1600°C to obtain a melt, and the high-temperature melt is poured, cooled, and finished to produce mechanical parts. High energy consumption, high pollution and other issues. In order to solve the problem of energy conservation and environmental protection, the state has banned small foundries with a scale of less than 10,000 tons; and with the development goal of "Made in my country 2025", my country's equipment manufacturing industry will inevitably develop greatly. By 2049, When the comprehensive strength enters the forefront of the world's manufacturing powers, the demand for mechanical parts will also be gre...
