Description

(54) DEVICE FOR LUBRICATING THE COOLING The invention relates to devices for supplying a cutting fluid (coolant) to the cutting zone and can be used for grinding with an abrasive rotating wheel. A device is known that protects the grinding zone from the effects of air currents created by a rotating circle. In this device, in addition to the main nozzle, through which coolant is supplied to the grinding zone, there is also an additional valve that is located outside the grinding zone in front of the main nozzle in the direction of rotation of the circle. The coolant flowing from this nozzle is directed perpendicularly to the periphery of the circle and forms a hydraulic barrier to the air flow, cutting it off from the surface of the circle. Liquid is supplied to both nozzles with one LlJ pump. A disadvantage of a device with a hydraulic screen is the need to use a high-pressure liquid pump for providing high kinetic energy of the screen strings. This leads to an increase in the additional consumption of coolant, its splashing, and an increase in the amount of drainage of coolant. When using a pneumatic barrier, there is a high flow rate in the box. The purpose of the invention is to reduce the energy consumption needed to create grinding screens during grinding using coolant. This goal is achieved by the fact that a nozzle for creating a barrier is connected by a device inserted in the device B and placed in the same housing with a source of compressed air, said pipes being interconnected by inclinations in the direction of the pipeline for supplying compressed air case. The drawing shows the proposed device, the cut.

Claims (2)

The claims of the stream 2₽ / fed to the grinding wheel well cutting. Compressed air is supplied through the pipeline; When air passes through the inclined openings 7, a vacuum is created, and part of the liquid from pipeline 4 enters pipeline 6, where it mixes with the air flow 5, forming an air-liquid mixture. The high-pressure flow of the air-liquid mixture is supplied to the periphery and the ends of the circle, cutting off the air layers and free particles at a high speed. The proposed device allows to reduce the consumption of compressed air, compared with the air screen with equal screening efficiency by ΙΟΙ 2 times, and πρ compared with the device, A device for supplying a lubricant-coolant ₍ coolant fluid) to a rotating grinding wheel, comprising a coolant nozzle connected by a pipe placed in the housing with a supply source thereof, and a nozzle designed to create a barrier and installed in front of the circle mentioned in the direction of rotation, characterized in that, in order to reduce energy consumption, the nozzle for creating a screen is connected by a pipe inserted into the device and placed in the same housing with a compressed air supply source, the pipes being ineny interconnected via inclined towards the pipeline for supplying compressed air holes formed in the housing. displacement '
