LY-12 hard aluminum pipe drawing lubrication emulsified oil and production method thereof

Abstract

The invention discloses an LY-12 hard aluminum pipe drawing lubrication emulsified oil. The LY-12 hard aluminum pipe drawing lubrication emulsified oil comprises the following raw material components in percentage by weight: 8 to 12 percent of oleic acid, 8 to 12 percent of triethanolamine, 1 to 4 percent of zinc naphthenate, 1 to 6 percent of turkey red oil, 1 to 6 percent of nonionic surfactant, 1 to 8 percent of zinc dialkyl dithiophosphate, 1 to 8 percent of dibutyl phthalate, 0.1 to 0.3 percent of propyl benzene triazole, 0.5 to 0.10 percent of absolute ethyl alcohol, 10 to 35 percent of machine oil, and aviation kerosene in balancing amount. The production method comprises the following steps: dissolving the propyl benzene triazole into the absolute ethyl alcohol for later use; adding the aviation kerosene and the machine oil into a special reaction kettle for oil; starting a stirrer and controlling the rotating speed to be 60 turns / minute; then sequentially adding the calculated and weighed oleic acid, triethanolamine, zinc naphthenate, turkey red oil, nonionic surfactant, zinc dialkyl dithiophosphate, dibutyl phthalate and propyl benzene triazole solution into the reaction kettle, stirring for 15 to 20 minutes after each of the raw material is added, continuing to stir for 2 hours after all the raw materials are added; and reducing the temperature to normal temperature.

Description

technical field [0001] The invention relates to a lubricating emulsified oil for drawing process and its production method, especially a kind of LY-12 duralumin pipe drawing which can prevent local overheating of the drawn metal pipe, oxidative discoloration and ensure the surface smoothness and brightness of the finished product. Lubricating emulsified oil and production method thereof. Background technique [0002] The drawing process is a typical metal processing method. It is a plastic processing process that reduces the cross-sectional area of ​​the metal processing material through the die hole core under the action of drawing to obtain a high-precision, high-gloss wire or pipe. During the drawing process, due to the large amount of metal deformation and the continuous generation of new friction surfaces, lubricating emulsified oil is required to lubricate and cool the metal material and mold. Lubricating emulsified oil plays a vital role in such a huge extrusion and ...

AI Technical Summary

Problems solved by technology

At present, the drawing lubricating emulsified oil of LY-12 duralumin pipe has the problems of poor cleaning performance and poor cooling effect, so that after repeated drawing, a large amount of metal powder adheres to the surface of the drawn pipe and the edge of the hole core. As a result, the friction coefficient between the two increases sharply, which not only reduces the surface finish and brightness of the drawn workpiece sharply, but also aggravates the wear and tear on the mold, affecting the service life of the mold; in addition, the cooling effect is not ideal, often occurs due to LY-12 The quality problem of broken pipe due to local overheating of duralumin pipe or mold

In addition, due to poor cleaning performance, it will have a negative impact on the quality of heat treatment and annealing in the subsequent process of drawing metal pipes
