Abstract
The utility model discloses a plasma airflow compression focus nozzle, including the nozzle body, the inside semi -sealed structure who is equipped with the cavity on the nozzle body, nozzle body head are equipped with the nozzle bore, and nozzle body rear portion is equipped with and is used for the screw thread connected with the plasma burning torch, and nozzle body front end is equipped with the shower nozzle, the middle position of nozzle body head is located to the nozzle bore, the nozzle body is made by tellurium copper or chromium zirconium copper product, the shower nozzle is awl body structure. The shower nozzle for the air current accumulation point of awl body structure and conical body before the nozzle bore between the 2 -15mm. The utility model discloses economic benefits is obvious, and material hardness and intensity are big, resistant scaling loss, and simple structure is compact, job stabilization, the cutting quality improves, and the cooling effect is showing more, and life increases, and electric conductive property and heat conductivility all obviously improve.
Description
Technical field
The utility model relates to a kind of nozzle, is specifically related to a kind of plasma air-flow compression and focuses on nozzle.
Background technology
Plasma cutting is metal local melting and the evaporation that utilizes the heat workpiece incision of high-temperature plasma electric arc, and discharge motlten metal to form a kind of processing method of otch by the isoionic momentum of high speed, plasma cutting coordinates different working gas can cut the metal that various oxygen is difficult to cutting, especially for non-ferrous metal (stainless steel, copper, aluminium etc.) cutting effect better, in the time of the little metal of cutting thickness, plasma cutting speed is fast, especially in the time of cutting normal carbon steel plate, speed can reach 5-6 times of oxygen cutting method, cut surface is bright and clean, thermal deformation is little, and almost there is no a heat affected area, nozzle is one of vitals of CUT, its life-span length directly affects cut quality and production efficiency, but in existing cutter sweep, nozzle life is mostly shorter, nozzle is jet often concentrated not, cutting effect is undesirable, be unfavorable for using, for the problems referred to above, ad hoc meter the utility model is solved.
Utility model content
The purpose of this utility model is to provide a kind of economic benefit obvious, and material hardness and intensity are large, simple and compact for structure, working stability, cut quality improves, and cooling effect is more remarkable, increase service life, and the plasma air-flow compression that electric conductivity and heat conductivility all obviously improve focuses on nozzle.
For achieving the above object, the utility model provides following technical scheme:
A kind of plasma air-flow compression focuses on nozzle, comprise nozzle body, the inner semi-enclosed structure that is provided with cavity on nozzle body, nozzle body head is provided with nozzle bore, nozzle body rear portion is provided with the screw thread for being connected with plasma cutting gun, and nozzle body front end is provided with shower nozzle.
As the further improvement of above-mentioned technology, described nozzle bore is located at the middle position of nozzle body head.
As the further improvement of above-mentioned technology, described nozzle body is made up of tellurium copper or chromium zirconium copper product.
As the further improvement of above-mentioned technology, described shower nozzle is bullet structure.
Described shower nozzle is that the air-flow accumulation point of bullet structure and bullet is before nozzle bore between 2-15mm.
Compared with prior art, the beneficial effects of the utility model are: the tapered body of sprinkler design, in the time of nozzle outer gas stream process bullet nozzle, air-flow compresses, the plasma arc forming from nozzle bore is strengthened compression again and is focused on, the cutting power of plasma arc is increased, reduce the consumption of nozzle, cutting speed and the cut quality of CUT are improved, accelerate the cooling velocity of nozzle, extend service life, because the ability of plasma arc increases, make plasma arc cutting speed accelerate to have strengthened the perpendicularity of plasma arc, increase cutting thickness, economic benefit is obvious, nozzle body selects tellurium copper or chromium zirconium copper product to make, hardness and the intensity of nozzle body are greatly increased, and simple and compact for structure, working stability, conventional spout cutting speed is accelerated relatively, cut quality improves, cooling effect is more remarkable, increase by 30% the service life of nozzle, volume reduces, electric conductivity and heat conductivility all obviously improve, use convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-nozzle body, 2-nozzle bore, 3-screw thread, 4-shower nozzle.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
A kind of plasma air-flow compression focuses on nozzle, comprise nozzle body 1, the inner semi-enclosed structure that is provided with cavity on nozzle body 1, the middle position of nozzle body 1 head is provided with nozzle bore 2, nozzle body 1 rear portion is provided with the screw thread 3 for being connected with plasma cutting gun, nozzle body 1 is made up of tellurium copper or chromium zirconium copper product, hardness and the intensity of nozzle body 1 are increased greatly, nozzle body 1 front end is provided with the shower nozzle 4 of cone body, shower nozzle 4 is designed to bullet, in the time of nozzle outer gas stream process nozzle, air-flow compresses, the plasma arc forming from nozzle bore 2 is strengthened compression again and is focused on, the cutting power of plasma arc is increased, reduce the consumption of nozzle, cutting speed and the cut quality of CUT are improved, accelerate the cooling velocity of nozzle, extend service life, because the ability of plasma arc increases, make plasma arc cutting speed accelerate to have strengthened the perpendicularity of plasma arc, increase cutting thickness, economic benefit is obvious.
When the utility model work, on conventional spout basis, improve nozzle form, adopt the nozzle of bullet structure, make to compress through the air-flow of nozzle, increase the cutting power of cutting machine, nozzle body 1 selects tellurium copper or chromium zirconium copper product to make, hardness and the intensity of nozzle body 1 are greatly increased, and simple and compact for structure, working stability, conventional spout cutting speed is accelerated relatively, cut quality improves, cooling effect is more remarkable, increase by 30% the service life of nozzle, volume reduces, electric conductivity and heat conductivility all obviously improve, use convenient.
The foregoing is only the utility model preferred embodiment; not thereby limit embodiment of the present utility model and protection domain; to those skilled in the art; the scheme that being equal to of should recognizing that all utilization the utility model descriptions and diagramatic content make replaces and apparent variation obtains, all should be included in protection domain of the present utility model.
