Description

54) LUBRICATION METHOD

one

The invention relates to the processing of metals by pressure and can be used in the lubrication of a tool or in the workpiece being deformed.

A known method of applying a lubricant involves supplying the solid and liquid phases to the mixing zone, mixing them and feeding the lubricant mixture to the lubricated surface using the dust spray tube l.

However, in the known method, the possibility of obliteration of the inner surface of the walls of the spray tube is not excluded, which leads to more frequent cleaning of its inner walls, and also reduces the solids content in the lubricant mixture, which ultimately reduces the performance and quality of the lubricant.

The purpose of the invention is to improve the performance and quality of the lubricant.

To this end, according to the method of applying a lubricant consisting in feeding the solid and liquid phases into the mixing zone, mixing them and feeding them onto the lubricated surface using a spray tube, mixing the liquid and solid phases of the lubricant mixture is done by

the liquid phase to the solid one; Passing through the spray tube.

The drawing shows a diagram of the method of applying lubricant.

The liquid phase 1 of the lubricant mixture is fed under pressure into the spray pipe 2. The solid phase of the 3-lubricant mixture in the form of a monolithic block is installed at the outlet of the spray pipe. As the liquid flows out of the tube, a jet is formed. Monolithic blocks are brought in to each other so that the melts with the ends of the blocks form a gap, which is always smaller than the diameter of a jet of liquid phase. As the jet passes through the gap, a process of hydroerosion occurs between the liquid and solid phases, and a mixture of two phases is formed. Under the action of a jet of particle

0 solid phase is removed from the gap and sprayed onto the tool and the workpiece 4. After the spraying process is stopped. (end of the lubrication cycle) the monoliths of the solid phase are reduced to a constant gap between their ends.

In order to intensify the hydroerosion process, depending on the properties of the solid phase in the monolith, the monolith is reported with high-frequency oscillations.

Pressed graphite is used as the monolith, and water is used as the liquid phase.

The proposed method of lubrication has high performance and quality lubrication.

Invention Formula

The method of applying a lubricant, consisting in supplying the solid and liquid phases to the mixing zone, mixing them and feeding them to the lubricated surface using a spray tube,

characterized in that, in order to increase the productivity and quality of the lubricant by eliminating the possibility of obliterating the inner surface of the walls of the spray tube with a solid phase, the mixing of the liquid and solid phases of the lubricant mixture is performed by acting on the solid phase when it passes through the spray tube.
