Abstract
The invention discloses an acetylene gas spray nozzle with a massive structure, and belongs to the field of cutting tools. The acetylene gas spray nozzle with the massive structure comprises a jacket, a spray nozzle body and a joint, wherein the spray nozzle body and the joint are casted integrally; an oxygen channel is formed in the center of the joint and is in the shape of a cone with a large top and a small bottom; the trumpet-shaped spray nozzle body with a small top and a large bottom is arranged under the oxygen channel; the jacket is in threaded connection with the joint; and an acetylene gas channel is formed in the upper end of the jacket. The acetylene gas spray nozzle with the massive structure is simple in structure and easy to implement; and the efficiency and the quality are improved effectively.
Description
Technical field
The present invention relates to cutting tool field, specifically a kind of overall structure acetylene gas nozzle.
Background technology
In machining, commonly use autogenous cutting and segmentation is implemented, so that following process to steel plate, steel pipe, rod iron, steel profile etc.In the prior art, the general structure of autogenous cutting nozzle is: by upper under comprise successively there is step head, vertical tube part and inverted round stage portion; The head of described cutting torch offers a circle preheat oxygen inlet hole, the combustion gas inlet hole corresponding with described preheat oxygen inlet hole, the below of described preheat oxygen inlet hole and described combustion gas inlet hole is mixing pore, and described preheat oxygen inlet hole and described combustion gas inlet hole are all mixing pore UNICOM with described; The lower end UNICOM fumarole of described mixing pore, described fumarole extends to the lower surface of cutting torch; The central authorities of this cutting torch are provided with oxygen outlet, and the bottom of described oxygen outlet is inlaid with Laval nozzle.During use, preheat oxygen inlet hole passes into preheat oxygen, and combustion gas inlet hole passes into combustion gas, and then both are final after mixing in mixing pore sprays from fumarole.But also there is following problem: cutting torch is connected with nozzle threads, easily pile up impurity in threaded connection place, affect the ejection of preheated oxygen, thus cause the slag of cutting more, do not reach the effect of accurate cutting.
Summary of the invention
The present invention aims to provide a kind of overall structure acetylene gas nozzle, to solve the problem.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of overall structure acetylene gas nozzle, it is characterized in that: comprise overcoat, nozzle, joint, nozzle and joint are that monoblock cast forms; Described joint central authorities are provided with oxygen channel, and oxygen channel is up big and down small coniform; Described oxygen channel is arranged with up-small and down-big horn-like nozzle; Described overcoat is connected with joint screw thread, and outer set upper side has acetylene gas passage.
Further, described acetylene gas passage end is communicated to jet hole.
Further, described acetylene gas passage is four, array centered by oxygen channel.
Beneficial effect of the present invention is:
One, nozzle and joint are that monoblock cast forms, and without being threaded, there is not in air flue the problem that there is impurity absorption, air-flow is more stable.
Two, joint central authorities are provided with oxygen channel, oxygen channel is up big and down small coniform, up big and down small coniform oxygen channel, after oxygen flows through tapered channel, form powerful taper swirling eddy, both can strengthen the concentrated injection of oxygen stream, gas cutting energy is more concentrated, and the slag produced is less.
Three, up-small and down-big horn-like nozzle, horn-like nozzle makes exit static pressure be greater than external atmosphere pressure, and air-flow is expanded diffusion in horn-like nozzle, accelerates further the oxygen stream of ejection.Be conducive to improving cutting speed and precision.
Four, acetylene gas passage is four, array centered by oxygen channel, makes acetylene gas and oxygen mix more abundant, there will not be wild effect during burning.
Accompanying drawing explanation
Fig. 1 is overall structure acetylene gas nozzle arrangements schematic diagram provided by the invention.
Mark in figure: 1 be oxygen channel, 2 be acetylene gas passage, 3 be joint, 4 be overcoat, 5 be nozzle, 6 for air-flow mixing section.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, a kind of overall structure acetylene gas nozzle, is characterized in that: comprise overcoat 4, nozzle 5, joint 3, and nozzle 5 and joint 3 form for monoblock cast; Described joint 3 central authorities are provided with oxygen channel 1, and oxygen channel 1 is up big and down small coniform; Described oxygen channel 1 is arranged with up-small and down-big horn-like nozzle 5; Described overcoat 4 is threaded with joint 3, and overcoat 4 upper end has acetylene gas passage 2.Described acetylene gas passage 2 one end is communicated to 5 mouthfuls, nozzle.Described acetylene gas passage 2 is four, array centered by oxygen channel 1.
In use, oxygen channel 1 is up big and down small coniform, up big and down small coniform oxygen channel, after oxygen flows through tapered channel, form powerful taper swirling eddy, both can strengthen the concentrated injection of oxygen stream, gas cutting energy is more concentrated, and the slag produced is less.Up-small and down-big horn-like nozzle 5, horn-like nozzle 5 makes exit static pressure be greater than external atmosphere pressure, and air-flow is expanded diffusion in horn-like nozzle 5, accelerates further the oxygen stream of ejection.Be conducive to improving cutting speed and precision.Oxygen stream and acetylene air-flow mix ejection at air-flow mixing section 6, and high velocity air can effectively remove the oxide remained on steel part.Adopt structure of the present invention simple, easily realize, effectively raise the efficiency and quality.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (3)
