Description
Technical field
The utility model relates to electrode cooling device, particularly a kind of plasma cutting electrode cooling device.
Background technology
At present, in plasma cutting system, conventional cooling water pipe has fixed and floating type two kinds, fixed water pipe compared with floating water pipe, water pipe and electrode coaxial in slightly poor, inhomogeneous cooling is even.Float water pipe under coolant pressure effect, slide to electrode base from cutting torch, but actual examination finds, size in use due to O type circle is different with the new and old degree of wear, whether water pipe slides in cutting torch and electrode can not be determined, so in use can not determine that water pipe end face and electrode base distance are definite value, cause cooling of electrode situation also uncertain thus.On the other hand, because floating water pipe radially wobbles in electrode body endoporus, the inhomogeneous cooling at electrode body blind end cooling position also can be caused even.
In view of this, need by improving existing cooling of electrode assembly, thus the plasma cutting electrode cooling device of a kind of stable cooling, effect brilliance is provided.
Utility model content
In order to solve the problem, the utility model provides the plasma cutting electrode cooling device of a kind of stable cooling, effect brilliance.
A kind of plasma cutting electrode cooling device in the utility model, comprise electrode body, cooling water pipe, described electrode body hollow elongate, wherein electrode body one end open, the other end is closed and is formed blind end, the arranged outside of described blind end has hafnium part, described hafnium part ionized gas produces plasma, the center of the blind end of described electrode body is provided with cylindrical boss, described cooling water pipe is hollow elongate, one end is coaxially connected with burning torch body, the other end is coaxially connected with electrode body, described electrode body elongated inner surface openend is uniform cylindrical face to another blind end, described cooling water pipe outer surface is provided with the first boss, coordinates with electrode body inner surface radial direction, and described cooling water pipe outer surface is provided with the second boss, axially coordinates, be provided with space between described cooling water pipe and electrode body with electrode body.
In such scheme, described first boss is three-pointed hollow star, and described leg-of-mutton angle is the angle of circular arc.
In such scheme, described second boss is provided with the projection of three circular arcs.
In such scheme, described first boss is quadrilateral shape, and the angle of described quadrangle is the angle of circular arc.
In such scheme, described second boss is provided with the projection of four circular arcs.
Advantage of the present utility model and beneficial effect are: the utility model provides the plasma cutting electrode cooling device of a kind of stable cooling, effect brilliance.When mounted, because electrode body inner surface is uniform cylindrical face, boss one end on cooling water pipe is circular arc, and boss diameter and electrode body inner surface diameter cooperatively interact, therefore electrode body can form radial and axial cooperation with cooling water pipe rapidly, cooling water pipe is coaxial with the central boss of electrode body blind end, both gap uniformity; After installing, cooling fluid is flowed into by water pipe endoporus, the gap between the uniform and stable central boss flowing through cooling water pipe and electrode body blind end, finally flows through electrode body inner surface and water pipe outer surface, completes cool cycles.Due in cooling procedure, cooling fluid uniform and stable by the gap between cooling water pipe and the central boss of electrode body blind end, make the cooling of electrode blind end evenly more stable, significantly increase electrode life.
