Description
Technical field
The present invention relates to CUT, particularly relate to the cooling structure of a kind of CUT.
Background technology
In CUT, the anterior cooling capacity of nozzle is to determine one of main factor in its service life.The at present anterior cooling to nozzle has two kinds of designs: the first design is directly to inject cooling water at nozzle bottom, simultaneously bottom the other end be the outlet cooling down water.In this design, there is a certain distance the front portion of cooling water inlet and nozzle and cools down water can be along the circumferential flow of nozzle, thus major part cooling water is not before having the front portion of flow nozzle, and directly cooling chamber is flowed out in space through circumference.Although this design is relatively simple, but owing to the cooling Power of the front portion to nozzle is more weak, the front portion of nozzle is easily damaged, and service life is relatively low, and job costs are higher.
The second design is by the guiding gutter circumferentially distributed in nozzle bottom processing, and cooling water can import the front portion of nearly nozzle.Owing to adding guiding gutter, the external diameter of nozzle is bigger, and the consumption to material is big, and the processing cost of nozzle is higher simultaneously.Owing to nozzle is that consumable accessory needs often to change, therefore overall work is relatively costly.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is to provide the cooling body of a kind of CUT, can the front portion of sufficiently cool nozzle.
For solving above-mentioned technical problem, the technical scheme is that and be achieved in that: the cooling structure of a kind of CUT, it includes nozzle casing and is placed in the nozzle in this nozzle casing, the cooling chamber of annular it is formed with between this nozzle casing and nozzle, the inwall of described nozzle casing is provided with at least one guiding gutter making cooling water directed flow, and described guiding gutter connects with this cooling chamber.
Preferably, the quantity of described guiding gutter is at least 6.
Preferably, the interval between described guiding gutter and nozzle is less than or equal to 0.5mm.
Preferably, described guiding gutter includes that, into water guiding gutter and water outlet guiding gutter, this water inlet guiding gutter all connects with described cooling chamber with water outlet guiding gutter.
Preferably, described water inlet guiding gutter includes orthogonal water inlet radial passage and water inlet axial passage；Described water inlet radial passage, water inlet axial passage and cooling chamber are sequentially communicated, and at least one described water inlet radial passage is communicated with water inlet.
Preferably, the quantity at least two of the water inlet radial passage connected with described water inlet.
Preferably, described water outlet guiding gutter includes orthogonal water outlet radial passage and water outlet axial passage；Described water outlet radial passage, water outlet axial passage and cooling chamber are sequentially communicated, and at least one described water outlet radial passage is communicated with outlet.
Preferably, the quantity at least two of the water outlet radial passage connected with described outlet.
The technique effect that the present invention reaches is as follows:
1, the cooling structure of CUT of the present invention, can the front portion of sufficiently cool nozzle, reduce the damage to nozzle, the service life of prolonging nozzle.
2, the cooling structure of CUT of the present invention arranges guiding gutter on nozzle casing, simplifies the structure of nozzle, reduces the consumption to material, reduces production cost.

Detailed description of the invention
As shown in Fig. 1 ~ Fig. 3, the cooling structure of CUT of the present invention includes nozzle casing 1 and nozzle 2, and nozzle 2 is fixed on nozzle carrier 3, and is placed in nozzle casing 1, and electrode 8 is placed in interior and with nozzle the front portion 21 of nozzle 2 and keeps a determining deviation.
The inwall of nozzle casing 1 is provided with at least one guiding gutter 4 making cooling water directed flow.As it can be seen, guiding gutter 4 can be cylindrical or part is cylinder, and guiding gutter 4 can be cast or flow forming forms by machining, but be not limited to this.
The cooling chamber 5 of annular it is formed with between nozzle 2 and nozzle casing 1.Cooling chamber 5 connects with guiding gutter 4, and the cooling water in guiding gutter 4 flows in cooling chamber 5, and the front portion 21 of nozzle can be made to be adequately cooled.
Interval between guiding gutter 4 and nozzle 2 is less than or equal to 0.5mm, it is to avoid cooling water is flowing into before cooling chamber 5, and directly the circumferential space through nozzle is flowed out, thus cannot sufficiently cool nozzle, nozzle is caused damage.
The quantity of guiding gutter 4 is arranged on more than 6, and the effect that guide cooling water is directed to cool down in cooling chamber 5 front portion 21 of nozzle is preferable.Actual production can be arranged as required to, be not limited thereto.Guiding gutter 4 includes into water guiding gutter and water outlet guiding gutter, and in the present invention, described water inlet guiding gutter and water outlet guiding gutter are provided with 14 altogether, and are evenly distributed on the most at equal intervals on the inwall of nozzle casing 1.
As shown in Figure 4 and Figure 5, described water inlet guiding gutter includes mutually perpendicular water inlet radial passage 41 and water inlet axial passage 42.Water inlet radial passage 41, water inlet axial passage 42 and cooling chamber 5 are sequentially communicated, and at least one water inlet radial passage 41 connection has water inlet 6.
As shown in Figure 6, the circumferential angle 411 of each water inlet radial passage 41 is β, and the circumferential angle 61 of water inlet 6 is θ, and 1.5 β≤θ≤60 °, to guarantee that at least two water inlet radial passages 41 can be entered to cool down water simultaneously.
Described water outlet guiding gutter includes vertical water outlet radial passage 41 and water outlet axial passage 42.Water outlet radial passage 41, water outlet axial passage 42 and cooling chamber 5 are sequentially communicated, and the connection of at least one water outlet radial passage 41 has outlet 7.As shown in Figure 6, at least two water outlet radial passages 41 connect with outlet 7.
The technique effect that the present invention reaches:
1, in the cooling structure of CUT of the present invention, nozzle design is simple, and scantling design is substantially reduced.
2, in the cooling structure of CUT of the present invention, nozzle casing is machined with guiding gutter, makes cooling water orientation flow in cooling chamber, the front portion of sufficiently cool nozzle, strengthen cooling effect, improve the service life of nozzle.
The above, only presently preferred embodiments of the present invention, it is not intended to limit protection scope of the present invention.
