The specific meaning of the above terms in the present application can be understood by those skilled in the art according to specific situations.
The multi-wire cutting is a cutting processing method which carries an abrasive material into a processing area of a workpiece to be processed for grinding through high-speed reciprocating motion of a metal wire, and simultaneously cuts a hard and brittle material into hundreds of thin sheets at one time.
During the cutting process, cooling fluid (such as cutting fluid) needs to be sprayed on the cutting piece to play the following roles: 1) Cooling, reducing the temperature of a cutting line (such as a diamond line) and a piece to be cut (such as a sliced material), and improving the durability of the diamond line and the processing quality of the slice; 2) The cutting fluid can penetrate into the clearance to form an adsorption film, so that the friction is reduced under the cutting load, and the lubricating effect is achieved; 3) Cleaning and chip removal, wherein the cutting fluid washes and removes fine chips generated in the cutting process or chips generated in grinding so as to prevent the machined chips from being scratched; 4) And (4) rust prevention.
Therefore, a corresponding fluid path circulation system is required to provide the cutting fluid. The existing liquid path circulating system arrangement mode can provide cooling liquid and recycle the cooling liquid. However, the existing liquid path circulating system cannot meet the requirements of some special application scenarios, for example, after a short-time parking, the flow of the cutting liquid cannot meet the use requirement in time, and the cutting efficiency is seriously affected because the flow needs to be made to meet the use requirement for a certain time.
In order to solve the above problem, the present application provides a liquid path circulation system, which includes a spraying device, a liquid supply device, a first pipeline and a second pipeline. The liquid supply device comprises a circulating inlet and a circulating outlet, and the circulating inlet is used for collecting used spray liquid. The first end of the first pipeline is communicated with the circulating outlet, the second end of the first pipeline is communicated with the spraying device, and the first pipeline is provided with a first control valve. A first end of the second pipeline is communicated with the inlet of the first control valve, and a second end of the second pipeline is communicated with the circulating inlet.

In addition, the liquid supply device can also provide other liquids besides cutting liquid, such as cleaning liquid, cooling oil and the like, and the spraying device can be a spraying device for cleaning equipment or cooling for cooling other parts, such as cooling of driving equipment. For convenience of description, the liquid path circulation system of the present application is described below in conjunction with supplying liquid to the spraying device in the wire cutting machine for spraying the workpiece to be cut.

Of course, it will be understood by those skilled in the art that the heat exchange device may be configured in other forms, such as a tubular heat exchanger or a finned heat exchanger, according to the needs of a specific application scenario. Further, the heat exchanger may not be provided.

During normal operation and short stops, the third line 18 is disconnected by closing the third control valve 181, further avoiding unnecessary circulation. When the equipment is stopped for a long time, the third control valve 181 is opened, so that unnecessary heat exchange and filtration are avoided, and the energy consumption is further saved. Moreover, the outlet of the third control valve 181 is communicated with the second pipeline 17, so that the pipelines can be reasonably arranged and utilized, repeated arrangement is avoided, and cost is saved.
It should be noted that, those skilled in the art may also omit the third pipeline 18 according to the needs of the specific application scenario.
