Volatile stamping cutting oil composite for machining for machining of moderate-thickness aluminum plate and preparation method thereof

Abstract

The invention relates to volatile stamping cutting oil composite for machining of a moderate-thickness aluminum plate and a preparation method thereof. The stamping cutting oil composite comprises the following raw materials in percentage by weight: 90-95 percent of solvent oil, 1-4 percent of antiwear additive, 1-4 percent of oiliness additive, 0.5-2 percent of antirust additive and 0.2-1 percent of antioxidant; the solvent oil has low sulphur content, low aromatic hydrocarbon content, no toxicity and smell and has the kinematic viscosity of 1.5-3.5mm<2>/s at 20 DEG C; the antiwear additive is selected from phosphates; the oiliness additive contains more than one of fatty alcohol and fatty acid methyl ester; the antirust additive is sodium alkylsulfonate; and the antioxidant is an antioxidant BHT (butylated hydroxytoluene). The preparation method of the volatile stamping cutting oil composite for the machining of the moderate-thickness aluminum plate, provided by the invention, is simple and convenient; and the composite provided by the invention does not contain a chlorine extreme pressure agent, is a biological environment-friendly product and has the advantages of excellent extreme pressure lubrication performance and favorable demoulding performance, volatilization completeness, no trace leaving, no clean, extremely low smell, no irritation to skin, time and labor saving and capability of greatly prolonging the service life of a mould.

Description

technical field [0001] The invention relates to a punching and shearing oil composition, in particular to a punching and shearing oil composition that can be used for processing medium-thick aluminum plates and a preparation method thereof, which is suitable for aluminum fins and condensers in the air-conditioning and refrigeration industry, and can be used for punching and shearing Medium-thick aluminum plate with a thickness of 6mm-7.5mm, copper sheet stamping in air-conditioning systems, heating and cooling devices. Background technique [0002] Stamping is also called sheet forming. The so-called sheet forming refers to a forming method that uses sheets, thin-walled tubes, thin profiles, etc. as raw materials for plastic processing. Stamping involves an extremely wide range of fields and penetrates into all aspects of the machinery manufacturing industry. [0003] When stamping metal sheets such as aluminum, copper and other non-ferrous metals, stamping oil / Punching a...

Problems solved by technology

At present, the oil stain on the surface of the product is mainly cleaned by solvent cleaning or metal cleaning agent, but it is not safe to use, and it is easy to cause harm to the health of the operator, and the production efficiency is reduced and the cost of use is high.

[0007] At present, the general stamping oils on the market are only suitable for thin aluminum sheets with relatively small thickness, but they cannot meet the processing needs of medium-thick aluminum sheets with higher requirements for lubricating performance.
