Abstract
The utility model relates to an outer surface weld joint welding protection device of titanium equipment, including the bottom open -ended cover body, be fixed with on the lateral wall of the cover body and stretch into its inside intake pipe, the inner of intake pipe is sealed, set up a plurality of gas diffluence holes of equipartition on the both sides lateral wall of intake pipe respectively. The utility model discloses it is internal to stretch into the cover with the intake pipe to offer the gas diffluence hole of equipartition on the lateral wall of the both sides of intake pipe, can make protective gas evenly distributed in the cover body, thereby protect the welding seam better, improve the quality of welding seam.
Description
Technical field
The utility model relates to the protecting tool set-up during welding of titanium material, specifically a kind of titanium eguipment outer surface weld seam welding protection device.
Background technology
Titanium material at high temperature has the features such as chemically active and poor thermal conductivity, hot melt quantity are little, and the welding of titanium material is welded with other material exists very big difference.In order to ensure the quality of titanium eguipment weld seam, must carry out reliable argon shield by butt welded seam during welding, postwelding also will be protected the weld seam cooled.
In prior art, postwelding protection adopts protective cover usually.The common structure of protective cover is the cover body of an employing bottom opening, and cover body is communicated with an air inlet pipe.By cover body cover in welded joints, in cover body, pass into the protective gas such as argon gas from air inlet pipe, thus protection weld seam.The shortcoming of this protective cover is the protective gas skewness in cover body, and the protected effect of butt welded seam is undesirable, affects the quality of weld seam.
Utility model content
In view of this, in order to solve the bad problem of existing protective cover protected effect, the titanium eguipment outer surface weld seam welding protection device that the utility model provides a kind of protected effect good.
The technical solution of the utility model is: a kind of titanium eguipment outer surface weld seam welding protection device; comprise the cover body of bottom opening; the sidewall of described cover body is fixed with the air inlet pipe in the portion of inserting into the inner; the inner of described air inlet pipe is closed, and the both sides sidewall of described air inlet pipe offers respectively uniform multiple gas distribution holes.
Further, described cover body is enclosed by top board, shroud upper panel, rear cowl, left plate and right plate and forms, described shroud upper panel, described left plate and described right plate are all perpendicular to described top board, described rear cowl is obliquely installed and angle between described rear cowl and described top board is obtuse angle, described air inlet pipe is arranged on shroud upper panel, and its axis is parallel with described top board, described left plate and described right plate respectively.
Further, the base of described rear cowl has weld seam and introduce breach.
Further, the base of described left plate and described right plate is the arc of identical depression.
The utility model compared with prior art, there is following technique effect: 1, air inlet pipe stretches in cover body by the utility model, and on the both sides sidewall of air inlet pipe, offer uniform gas distribution hole, protective gas can be made to be uniformly distributed in cover body, thus protect weld seam better, improve the quality of weld seam; 2, rear cowl is obliquely installed, and can avoid producing with welding equipment interfering; The base of 3, rear cowl has weld seam and introduce breach, rear cowl and weld seam can be avoided to interfere; 4, the base of left plate and right plate is set to arc, makes the utility model be applicable to the protection of circumferential weld.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
In Fig. 1-Fig. 2, comprise weld seam 10, front protection tracheae 20, welding position 30, cover body 40, rear cowl 41, top board 42, gas distribution hole 43, right plate 44, shroud upper panel 45, air inlet pipe 46, left plate 47, air inlet pipe end plate 48, weld seam introducing breach 49.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
With reference to figure 1, Fig. 2, a kind of titanium eguipment outer surface weld seam welding protection device, comprises the cover body 40 of bottom opening.Cover body 40 is enclosed by top board 42, shroud upper panel 45, rear cowl 41, left plate 47 and right plate 44 and forms, shroud upper panel 45, left plate 47 and right plate 44 are all perpendicular to top board 42, and rear cowl 41 is obliquely installed and angle between rear cowl 41 and top board 42 is obtuse angle.The object that rear cowl 41 is obliquely installed is interfered in order to avoid producing with welding equipment.
The sidewall of cover body 40 is fixed with the air inlet pipe 46 in the portion of inserting into the inner.Air inlet pipe 46 is arranged on shroud upper panel 45, and its axis is parallel with top board 42, left plate 47 and right plate 44 respectively.The inner of air inlet pipe 46 is closed by air inlet pipe end plate 48, the both sides sidewall of air inlet pipe 46 offers respectively uniform multiple gas distribution holes 43.
The base of rear cowl 41 has weld seam and introduce breach 49.The setting that weld seam introduces breach 49 is to avoid weld seam, avoids rear cowl 41 and weld seam to interfere.
When the utility model is used for protection cylindrical shell circular weld, the base of left plate 47 and right plate 44 is set to the arc of identical depression, and the radian of arc matches with the external diameter of cylindrical shell.
As shown in Figure 1, when utilizing the utility model protection weld seam 10, before the front portion of welding position 30 is provided with logical protective gas, protects tracheae 20, the utility model is set at the rear portion of welding position 30.In air inlet pipe 46 of the present utility model, pass into the protective gas such as argon gas, gas flows out from the gas distribution hole 43 of air inlet pipe 46, and is evenly full of cover body 40, thus protects weld seam 10 better.
It should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
