Low-energy-consumption low-temperature composite spray cutting system

Abstract

The invention discloses a low-energy-consumption low-temperature composite spray cutting system and belongs to the technical field of machining and clean production. The low-energy-consumption low-temperature composite spray cutting system mainly comprises a filter pressure reducing valve, a fine oil spray generation device, a low-temperature liquid production device, a low-temperature cold air atomization device, a common conveying pipe and an insulation conveying pipe. The fine oil spray generation device comprises a partition plate, an atomization chamber, a precipitation chamber, a micro oil pump and an oil capacity control valve. The low-temperature liquid production device comprises a liquid storage tank, a semiconductor refrigerating or heating device, a liquid level control valve and an insulation conveying pipe; the low-temperature cold air atomization device comprises a vortex refrigeration device which produces cold air and a nozzle; and the nozzle comprises a fixed sheet, an oil spray thin pipe outlet, a water thin pipe outlet, a mixing cavity and a spray outlet channel. The system forms low-temperature composite oil spray in which a layer of thin oil film is covered on water drops by using purely oily plant oil based cutting oil with good performance, frozen low-temperature purified water and low-temperature cold air, accurately sprays the low-temperature composite oil spray onto a metal cutting area at high speed, and fulfills the aims of effective cooling and lubrication.

Description

technical field [0001] The invention relates to the technical field of machining clean production, in particular to a low-energy-consumption low-temperature composite spray cutting system. Background technique [0002] A large number of metalworking fluids (oily machining fluids and water-soluble machining fluids) are used in machining to achieve the effects of lubrication, cooling and cleaning. With the rapid development of the modern processing industry, the extensive recycling of water-soluble processing fluids (such as emulsions, solubles, and dissolving liquids), as well as the massive discharge of processing waste liquids, have caused serious environmental pollution problems. The processing fluid not only contains extreme pressure additives such as sulfur, phosphorus, chlorine and other elements that are harmful to the human body, but also contains surface active additives. When fine chips are mixed in the processing process, it is difficult to separate the additives i...

Problems solved by technology

Increased tool temperature leads to softening of the cutting edge of the tool, which accelerates tool wear

In the case of continuous cutting, especially the processing of superalloys and titanium alloys that are extremely difficult to machine, because the cutting area will generate a lot of heat, simply using a small amount of vegetable cutting oil will easily lead to high temperature in the cutting area
