SU152162A1 - Device for cooling and lubricating the cutting zone - Google Patents

Description

Devices for cooling and lubricating the cutting area with sprayed liquids are known, consisting of an emulsion tank, a distributor, a mixer, a piping system, a nozzle tube, and devices for adjusting the compressed air supply.

The described device is characterized in that in it the distributor is equipped with an interchangeable diaphragm, a nozzle and a chamber for the primary mixing of liquid with air and is connected to a mixer installed in maximum proximity to the cutting zone where the mixture obtained in the secondary mixing with air occurs.

Such an embodiment of the device ensures the stability of operation and the constancy of the consumption of the sprayed liquid.

FIG. 1 shows the described device; in fig. 2 - the distributor of this device.

The device works as follows: compressed air from the shop network through the filter / (Fig. 1), reducing valve 2 and solenoid valve 3 enters the distributor 5 installed on the emulsion tank 4, in which the primary mixing of air with liquid and the formation of an air-liquid mixture occurs .

Further, the dry air and the air-liquid mixture formed through separate lines are directed to the mixer 6, which is as close as possible to the cutting zone, where they are mixed again and through the holder 7 and the nozzle 8 are directed to the cutting zone.

In the distributor (FIG. 2), the air, the passage between the distributor nozzle 9 and the interchangeable diaphragm 10, creates a vacuum in the primary nozzle 9 and draws fluid from the tank through the filter And and the tube 12 screwed into the distributor housing 13.

The liquid exiting the distributor nozzle 9 is picked up by compressed air and sprayed. The air-liquid mixture through the holes b enters further into the chamber formed by the housing 13, the glass M, the neck of the tank 15 and the reflector 16.

In this chamber, large droplets beat off along the walls and flow back into the tank, and small droplets of liquid together with air are directed to mixer 6 (Fig. 1), where compressed air flows in a separate slap and where the mixture obtained in the distributor is mixed again.

Subject invention

A device for cooling and lubricating the cutting area with sprayed liquids, consisting of an emulsion tank, a distributor, a mixer, a piping system, nozzle tubes, and compressed-air supply control devices, characterized in that, in order to ensure steady operation and consistency of consumption, the fluid in it, the distributor is equipped with a replaceable diaphragm, a nozzle and a chamber for the primary displacement of the liquid with air and is connected with a mixer for the secondary displacement of the mixture obtained in the distributor set to the maximum No proximity to the cutting area. f J
