Abstract
The utility model relates to the technical field of a cutting machine, and discloses a high-temperature resistant nozzle and a plasma cutting machine, wherein the high-temperature resistant nozzle comprises a nozzle body and a nozzle head connected with the nozzle body; and the nozzle head is provided with a nozzle orifice which is internally provided with a ceramic tube. According to the high-temperature resistant nozzle provided by the embodiment of the utility mode, the ceramic tube is arranged in the nozzle orifice of the nozzle head, so that compared with the nozzle made of common metal, the high-temperature resistant nozzle has better temperature resistance (the resisted temperature is improved by about 700DEG C), and is longer in service life and lower in comprehensive use cost.
Description
Technical field
The utility model relates to the cutting machine technical field, particularly relates to a kind of high temperature resistant nozzle and CUT.
Background technology
The incision principle of CUT is that the high speed and high pressure plasma gas is blown out from nozzle; And the high plasma column (can reach 10000 ℃～30000 ℃) of formation temperature between steel plate; Utilize the heat of high-temperature plasma electric arc to make the metal local melting and the evaporation of workpiece incision, and get rid of motlten metal to form a kind of processing method of otch by the isoionic momentum of high speed.
In the prior art, the nozzle of CUT in use because the frequent plasma column of contact high-speed and high-temperature; Easy scaling loss; And more existing nozzles use brass material or tungsten alloy material to process, and get high temperature resistant problem though solved nozzle preferably; Lack or cost an arm and a leg its service life, is unfavorable for that manufacturing enterprise practices thrift cost.
Therefore, how proposing the good and comparatively economic scheme of a kind of high-temperature resistant result to nozzle, is the technical barrier that those skilled in the art need to be resolved hurrily.
The utility model content
The utility model is intended to propose a kind of high temperature resistant nozzle and CUT, to solve existing nozzle heatproof weak effect or the high problem of use cost.
On the one hand, the utility model provides a kind of high temperature resistant nozzle, and this high temperature resistant nozzle comprises mouth body and the nozzle head that links to each other with this mouth body, and said nozzle head is provided with spout, wherein, is provided with earthenware in the said spout.
Further, the inwall interference fit of said earthenware and said spout.
Further, said earthenware is the oxide ceramics pipe.
Further, the joint face of said mouth body and said nozzle head is a taper surface.
On the other hand, the utility model also provides a kind of CUT, and this plasma cutting machine is provided with above-mentioned each described high temperature resistant nozzle.
Further, said CUT is provided with the installing hole that is used to install said high temperature resistant nozzle, is provided with first sealing ring and second sealing ring between the periphery wall of said mouth body and the inwall of said installing hole.
Further, be provided with the 3rd sealing ring between the inwall of the periphery wall of said nozzle head and said installing hole.
Further, said first sealing ring, said second sealing ring and said the 3rd sealing ring are the O RunddichtringO.
A kind of high temperature resistant nozzle that the utility model provides and a kind of CUT that is provided with this high temperature resistant nozzle; In the spout of nozzle head, be provided with earthenware; Make this nozzle have better temperature resistance ability (but the heatproof degree improves about 700 ℃) than the nozzle of common metal material; And longer service life, simultaneously comprehensive use cost is lower.
Description of drawings
A kind of high temperature resistant structure of nozzle sketch map that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the another kind of specific embodiment of high temperature resistant nozzle shown in Figure 1.
The specific embodiment
In order to make those skilled in the art understand the technical scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and specific embodiment.Should be pointed out that description and the description order to concrete structure only is the explanation to specific embodiment in this part, should not be regarded as that the protection domain of the utility model is had any restriction.
Please refer to Fig. 1, a kind of high temperature resistant structure of nozzle sketch map that Fig. 1 provides for the utility model embodiment.
As shown in the figure, this high temperature resistant nozzle mainly comprises mouth body 3, earthenware 6 and nozzle head 7, and wherein, an end of nozzle head 7 links to each other with mouth body 3 through taper surface; Nozzle head 7 is provided with spout 5, in the said spout 5 earthenware 6 is installed, the inwall interference fit of earthenware 6 and shower nozzle 5; Preferably, earthenware 6 is the oxide ceramics pipe.
In use, this high temperature resistant nozzle is arranged on the CUT, and this plasma cutting machine is provided with installing hole (being arranged on usually on the spray handle); Be placed in the installing hole in the high temperature resistant nozzle; The periphery wall of mouth body 3 is provided with two grooves, is used to hold first sealing ring 1 and second sealing ring 2, and the periphery wall of nozzle head 7 is provided with a groove; Be used to hold the 3rd sealing ring 4, above-mentioned three sealing rings are used for playing when high temperature resistant nozzle is installed in this installing hole sealing function.
As shown in Figure 2; The figure shows the another kind of specific embodiment of the foregoing description; The high temperature resistant nozzle of this embodiment has aforesaid mouth body 3, nozzle head 7, spout 5 and earthenware 6; And on the periphery wall of mouth body 3, be provided with the groove that is used to hold first sealing ring 1 and second sealing ring 2, its difference is the position that is provided with of the 3rd sealing ring 4, in this embodiment; The 3rd sealing ring 4 is arranged on the periphery wall of mouth body 3, and the whole periphery wall of nozzle head 7 links to each other with mouth body 3 through taper surface.
Need to prove that in the foregoing description, first sealing ring 1, second sealing ring 2 and the 3rd sealing ring 4 are the O RunddichtringO, can certainly use the sealing ring of other types as required, for example the VL RunddichtringO.
Need to prove that in the foregoing description, the joint face between nozzle head 7 and the mouth body 3 is a taper surface, but in other embodiments, also can as required this joint face be arranged to other shapes, for example stepped.
Need to prove that in the foregoing description, spout 5 is a cylindrical channel, correspondingly, earthenware 6 also is the cylinder passage, but in other embodiments, spout 5 can also be the passage of other shapes, tapered channel for example, and correspondingly, earthenware 6 is the taper earthenware.
The utility model also provides a kind of CUT; This plasma cutting implement has above-mentioned high temperature resistant nozzle; Because above-mentioned high temperature resistant nozzle has above-mentioned technique effect, therefore, the CUT with this heatproof nozzle also should possess the corresponding techniques effect; Its practical implementation process is similar to the above embodiments, does not give unnecessary details now.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
