Near dry cutting liquid supply apparatus

Abstract

The invention relates to a quasi-dry cutting liquid supply device, which comprises a plurality of chamber walls, a chamber, a partition, an adjusting valve, a hybrid chamber, a drain pipe, a liquid guide pipe, an inner pipe, an outer pipe, an inlet for compressed gas, and a nozzle; wherein, the partition divides the chamber into two sub-chambers for respectively holding different lubricants, which enter the pipeline under the action of the compressed gas, and the quantity of the lubricants can be selected by means of the adjusting valve; the inner pipe and the outer pipe form a double-layer tubular structure, and the nozzle also adopts a double-layer structure. The device can be used as a liquid supply device for oil-less lubrication, low temperature cutting, and liquid nitrogen cooling and process, and can regulate the usage quantity of the lubricants in a reasonable manner. The liquid supply device in the invention has the advantages of simple structure, low costs, less resource consumption, and suitability for mass production. Moreover, by using the nuisance and pollution-free green lubricants, the liquid supply device effectively solves the problems in the prior liquid supply systems, such as large usage of cutting liquid, difficulty in controlling, and severe environmental pollutions.

Description

(1) Technical field: [0001] The invention relates to a liquid supply device for quasi-dry cutting, in particular to a liquid supply device for quasi-dry cutting which atomizes a lubricant and sprays it to a cutting area at a relatively high speed to realize lubrication and cooling of the processing area. The utility model relates to a liquid supply device belonging to the field of mechanical processing. (two) background technology: [0002] In the process of mechanical processing, the disadvantages of using a large amount of cutting fluid are becoming more and more obvious: from the perspective of environmental pollution, on the one hand, the waste cutting fluid is an important source of soil and air pollution; From the perspective of use cost, on the one hand, the purchase, storage, and post-processing of cutting fluid are expensive. On the other hand, corrosive cutting fluid will change the color of the workpiece and corrode the gasket; from the perspective of processing q...
