Description

Technical Field

[0001] The utility model belongs to the technical field of water spraying for wire cutting machine tools, and more specifically, particularly relates to a water spraying device for wire cutting machine tools. Background Art

[0002] The working mechanism of wire cutting machine is to utilize the principle of "discharge machining" to electro-erode the conductive material (spark discharge) to achieve the purpose of cutting. In order to ensure that the electrode wire is not melted by high temperature, the solution adopted in the industry is usually to spray liquid medium on the surface of the electrode wire for cooling.

[0003] When installing the existing water spray device of the wire cutting machine tool, it is not convenient to place the electrode wire in the center of the nozzle of the circular array, and the liquid column sprayed by the nozzle may deviate from the electrode wire, which may cause poor heat dissipation of the electrode wire; at the same time, the existing water spray device usually uses a filter to filter the liquid medium, and the filter may be blocked during use; and the filter may be blocked, resulting in the inability to spray the liquid medium on the surface of the electrode wire for cooling, which reduces the practicality of the water spray device.
