Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Example one

Referring to fig. 1-3, a water plate water nozzle of a wire cutting machine comprises a nozzle 1 and a water inlet pipe 10, wherein the water inlet pipe 10 is fixedly connected to one side of the nozzle 1, the nozzle 1 is provided with a through hole 3, the through hole 3 is used for penetrating a cutting wire 4 for cutting by the wire cutting machine, a spiral water channel 2 is arranged in the side wall of the nozzle 1, and the spiral water channel 2 is communicated with the water inlet pipe 10; a water spray nozzle 12 is arranged on the spiral water channel 2, and one end of the water spray nozzle 12 is communicated with the through hole 3; the water spray ports 12 are reversely arranged on the opposite sides in the spiral pipeline 2; when the cutting wire 4 is used for cutting a plate, cooling liquid enters the spiral water channel 2 through the water inlet pipe 10, water flows in the spiral water channel 2 and is sprayed into the through hole 3 through the water spray nozzle 12, then the water moves along the tangential direction of the diameter of the cutting wire 4, and then under the action of tangential impact force of the water flow, impurities stained on the cutting wire 4 are cleaned, so that the cutting quality of the cutting wire 4 in subsequent cutting is ensured; because the multilayer water jet 12 is arranged in the spiral pipeline 2, and then the water flow is vortex-shaped and flows down in the through hole 3, and then the cutting wire 4 is wrapped in the water flow, and because the water flow rotates to flow down along the outer contour of the cutting wire 4, the further cutting wire 4 is enabled to be evenly stressed, and the radial shaking can not occur along with the water flow.

Furthermore, the through holes 3 are used for penetrating the cutting wires 4, because the water flow increases along with the distance of the passing spiral water channel 2 and the number of the passing water spray nozzles 12 increases, the flow rate of the water flow decreases along with the increase, and further in order to enable the cutting wires 4 to obtain a good water flow wrapping effect, the through holes 3 are arranged to be conical holes, the diameter of the water outlet end of each through hole is smaller than that of the water inlet end, and meanwhile, because the diameter of the through holes 3 through which the water flow passes becomes smaller gradually, the speed of the water flow becomes higher along with the diameter, and further washing and cleaning are carried out on the surfaces of the cutting wires 4.
