Abstract
The invention discloses a shielding gas nozzle which comprises a nozzle body, wherein the nozzle body is made of a red copper material, the nozzle body comprises a sprayer, the upper end face of the sprayer is a downward-concave arc-shaped structure with an inclination angle of 60 degrees, a spout is arranged on the sprayer, the cross section of the spout is elliptical, and the caliber of the spout is 11 mm. According to the shielding gas nozzle disclosed in the technical scheme, the structural design that the upper end face of the sprayer is inclined by a certain angle and the structural design of the caliber and the cross-section of the spout can increase the protected region, ensure the gas jet laminar flow stability, allow a shielding gas to be completely injected into a welding seam bevel, solve the problem that a welded piece is oxidized due to umtimely reduction of temperature caused by high-speed welding, and improve the welding quality.
Description
Technical field
The present invention relates to a kind of nozzle, relate in particular to a kind of laser welding protective nozzle that is used for.
Background technology
Laser weld is a kind of novel welded and high efficient method, usually needs to use inert gas to protect, and preventing device oxidation, hydrogenation, and causes metallicity to go wrong.Protect gas jets mostly to adopt the carbon steel seamless steel pipe to process now, its shower nozzle is cylindrical, and the nozzle exit is rounded; This structure, when depth of weld groove weld, columniform nozzle face is wideer than weld groove; Laminar flow is unstable when the gas ejection occurring, and nozzle can't be transported to protection gas in the groove, and groove bottom gas shield is not in place; And, cause producing weld defect because of high-speed welding causes the weldment problem of oxidation of lowering the temperature untimely.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of protection gas jets effective and that the laminar flow of giving vent to anger is stable of protecting.
Technical solution of the present invention is achieved in that a kind of protection gas jets, comprises nozzle body, and said nozzle body adopts the red copper material to process; Said nozzle body comprises shower nozzle; Said shower nozzle upper surface is the recessed arcuate structure of 60 ° of inclinations; Said shower nozzle is provided with spout; Said spout cross section ovalize.
Preferably, said spout bore is 11mm.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Protection gas jets of the present invention; Structural design through shower nozzle upper surface inclination certain angle and to the structural design in spout bore and cross section; Increased the protection zone, guaranteed that gas ejection laminar flow is stable, protection gas can be injected in the weld groove fully; Avoided simultaneously having improved the quality of welding because of high-speed welding cause the lowering the temperature problem of untimely weldment oxidation.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the perspective view of protection gas jets of the present invention;
Accompanying drawing 2 is the front view of protection gas jets of the present invention;
Accompanying drawing 3 is the left view of protection gas jets of the present invention;
Wherein: 1, nozzle body; 2, shower nozzle; 3, spout; 4, shower nozzle upper surface.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1,2,3 is a kind of protection gas jets of the present invention, comprises nozzle body 1, and the fusing point of red copper is high, is difficult for making the nozzle temperature distortion, and nozzle body 1 adopts the red copper material to process; Nozzle body 1 is provided with shower nozzle 2; For making protection gas help forming laminar flow; Holdup time is long in the protection zone; It is 60 ° recessed arcuate structure that shower nozzle upper surface 4 is designed to the angle of inclination, and shower nozzle 2 is provided with the spout 3 that bore is 11mm, the cross section ovalize of spout 3; Both increase the protection zone, helped blowing away the plasma that Yin Gaowen produces again.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
