A wire guide with drainage structure

Abstract

The invention discloses a wire guide with a water draining structure. The wire guide with the water draining structure comprises a water draining table and a wire guide head, wherein the water draining table is shaped like a circular truncated cone, and the top surface of the water draining table is smaller than the bottom surface; the wire guide head is cylindrical; an inner thread installing hole is formed in the middle of the water draining table; an outer thread matched with the inner thread installing hole is arranged in the middle of the wire guide head; the middle of the wire guide head is screwed and fixed into the inner thread installing hole through engagement of the inner and outer threads; a plurality of water draining grooves are formed in the inclined lateral wall of the water draining table; and an electrode wire guide hole is formed in the middle of the wire guide head. In this way, work liquid sprayed on the surface of an electrode wire can be drained rapidly and prevented from flowing onto the surface of a workpiece and causing water draining ripples on the surface of the workpiece. Meanwhile, the wire guide head can play a role in supporting and limiting the electrode wire, and poor cutting precision caused by shaking of the electrode wire is avoided.

Description

technical field [0001] The invention relates to the field of wire cutting machine accessories, in particular to a wire guide with a drainage structure. Background technique [0002] The principle of the wire cutting machine is to properly tension the electrode wire and reciprocate relative to the workpiece to be cut at a certain speed and pressure. During the wire cutting process, in order to ensure that the cutting process can continue to effectively generate spark discharges Function, as well as timely removal of galvanic corrosion products and heat from the processing area, it is necessary to continuously and sufficiently flush the electrode wire in the cutting processing area with a working fluid (usually water), however, in the existing cutting process, the working fluid It cannot be quickly discharged from the surface of the electrode wire and penetrates into the surface of the workpiece to be cut, causing drainage water marks on the surface of the workpiece. At the sa...
