Problems solved by technology

Generally, the air flow at the outlet of the straight-through nozzle is not properly configured, so that when the nozzle sprays a large amount of low-temperature cold air, it will generate a lot of noise. This shortcoming limits the low-temperature micro-quantity lubrication technology to a large extent. promotion and use

Abstract

The invention relates to the technical field of near-dry cutting, in particular to a frost prevention nozzle used for low-temperature minimal quantity lubrication cutting. The nozzle comprises a nozzle body and a nozzle sleeve. The nozzle body comprises a fixed part, a rod part and a jetting part in sequence in a communicated mode. The fixed part is provided with a first close nipple. The bottom of the rod part is provided with external threads. The top end of the jetting part is provided with a jetting hole, and a gas divider is arranged in the jetting hole. The nozzle sleeve comprises a sleeve bottom, a sleeve middle and a sleeve diversion cone, wherein the sleeve bottom, the sleeve middle and the sleeve diversion cone are integrally formed. The sleeve bottom is provided with a second close nipple. The nozzle body is in threaded connection with the nozzle sleeve to form the frost prevention nozzle with a double-wall structure. The side wall of the sleeve bottom is provided with a gas hole close nipple. A gap structure is formed between the inner wall of the sleeve division cone and the outer wall of the jetting part. According to the nozzle, the outer surface of the nozzle and the edge of an outlet of the nozzle can be effectively prevented from being frosted, low-temperature cold air and minimal-quantity oil mist can be jetted through the same tube, the energy loss of the low-temperature cold air is small, and noise is low.

Description

technical field [0001] The invention relates to an anti-frost nozzle for low-temperature micro-lubricating cutting, in which a small amount of lubricating oil is mixed in the extremely low cold wind, and sprayed through the nozzle can effectively prevent the phenomenon of frosting and icing at the nozzle, which belongs to the green and high-efficiency quasi- Dry cutting technology field. Background technique [0002] Low-temperature micro-lubrication technology is a new type of quasi-dry cutting technology that mixes low-temperature compressed air with micro-quantity lubricating oil mist, sprays it to the processing area, and cools and lubricates the processing area. On the one hand, the high-pressure and high-speed flow of low-temperature cold air can drive a small amount of lubricating oil to be better sprayed to the processing area, and form a lubricating film on the surface of the processing area, effectively reducing the friction between the tool and the workpiece, the ...
