Device for cooling the cutting zone

The utility model relates to devices for processing materials by cutting, and in particular to devices for cooling the cutting zone.

A device for cooling the cutting zone, which contains at least one ionizer having a housing with a nozzle. The nozzle outlet is the ionizer outlet and is directed into the cutting zone. A corona electrode is installed in the ionizer body. A pipeline is installed between the ionizer body and the nozzle, and a pressure regulator of the lubricating-cooling medium is installed in the line in front of the ionizer. (RU patent No. 2125929, in 23Q 11/10, 1995)

The specified device cannot provide increased durability of the cutting tool.

The technical result of the claimed device is to increase the cooling efficiency of the cutting zone and provide increased resistance of the cutting tool.

The specified technical result is achieved by the fact that in the device for cooling the cutting zone containing at least two ionizers, each of which contains a hollow body with a nozzle for supplying a gaseous cutting fluid to the workpiece during metal cutting, according to the utility model, ionizers are installed with the ability to ensure the distance between the axes of symmetry of the gaseous cutting fluid flows on the workpiece that is selected from the ratio:

where: A is the distance between the axes of symmetry of the gaseous cutting fluid flows on the workpiece;

D is the diameter of the output nozzle of the ionizer:

L is the distance from the cut of the ionizer nozzle to the workpiece.

These features are significant and interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result

A D + 0.6 L,

This useful model is illustrated by a concrete example, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving a technical result.

The drawing schematically shows a device for cooling the cutting zone.

When milling, hobbing or drilling, that is, when the cutting zone is significant, it is not enough to have only one ionizer, it is necessary to have several ionizers, as shown in the drawing.

A device for cooling the cutting zone contains three ionizers 1. Each ionizer 1 comprises a hollow body 2 with a nozzle 3 for supplying a gaseous cutting fluid 4 to the workpiece 5 during metal cutting.

Ionizers 1 are installed with the possibility of ensuring the distance between the axes of symmetry of the flows 4 of the gaseous cutting fluid on the workpiece 5, which is selected from the ratio:

where: A is the distance between the axes of symmetry of the gaseous cutting fluid flows on the workpiece;

D is the diameter of the outlet of the ionizer nozzle;

L is the distance from the cut of the ionizer nozzle to the workpiece.

The discount of the device for cooling the cutting zone is as follows: The housing 2 of each ionizer 1 is installed near the processing zone of the part 5 so that the gaseous cutting fluid 4 formed by the nozzle 3 is supplied to the cutting zone and cools the workpiece 5 during the cutting process.

When processing metal by cutting, the workpiece 5 is brought into rotation at a given speed. The cutting tool 6 is brought to its surface, and with their .kontakte and relative relative movement, the workpiece 5 is machined. The cutting speed is set in accordance with the selected technology and changed depending on the workpiece material and the type of cutting tool, the type of equipment used, and so on.

Simultaneously with the processing of the part 5, a gaseous lubricating cooling medium is supplied to the ionizers 1 at a pressure of at least 0.04 atm, which is set using a standard pressure regulator (not shown in the drawing). Processed

 + 0.6L,

In a known manner, a gaseous cutting fluid coming out through nozzles 3 is formed into streams 4 from a gaseous cutting fluid, which also enter the cutting zone. The generated streams 4 from the gaseous lubricant-cooling medium, without interacting with each other, cool the cutting tool 6 and the workpiece material 5. In addition, such flows accelerate the formation of a thin oxide film on the surface of the workpiece material and the cutting tool, which serves as a lubricant and reduces heat generation in the zone cutting.

When using the claimed device, the tool life is almost doubled.
