Description
Technical field
The present invention relates to stainless steel laser welded tube inside weld forming field, specific design one stainless steel laser welded tube inside weld gas shield device.
Background technology
Stainless steel laser welded tube has the features such as speed of welding is fast, heat input is little, heat affected area is narrow, welding deformation is little, cold machine-shaping performance is good.Being mainly used in production high-grade car gas extraction system, particularly America and Europe is that auto vendor specifies use laser welding pipe.
Existing inside weld protection device is made up of bracing frame, breather; being characterized in simple in construction, especially at laser spot area trachea often by laser blown or blocking, sealing effectiveness is poor; inside weld degree of oxidation is serious, and have impact on weldquality to a certain extent.It addition, during long tube cuts short tube, due to the existence of coolant, inside weld surface quality is poor, there is slight corrosion phenomena, have impact on weldquality to a certain extent.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, length in service life, a kind of stainless steel laser welded tube inside weld gas shield device that can effectively protect inside weld for the above-mentioned state of the art.
The present invention solves the technical scheme that above-mentioned technical problem used: a kind of stainless steel laser welded tube inside weld gas shield device; including water inlet pipe, return pipe, breather and inside weld gas shield device cavity; it is characterized in that: described inside weld gas shield device cavity is provided with the installing hole of more than at least three for being installed into water pipe, return pipe, breather; the left part of described inside weld gas shield device cavity be provided with one before sealing-plug, the right part of described inside weld gas shield device cavity is provided with rear sealing-plug.
As improvement, described installing hole is provided with three, is followed successively by the first installing hole, the second installing hole and the 3rd installing hole from top to bottom, and described installing hole is a straight line and the sealing-plug surface being evenly distributed in inside weld gas shield device cavity.
As improvement, described front sealing-plug forms the cavity of opposing seal with rear sealing-plug.
As improvement, described water inlet pipe and return pipe run through described cavity through the first installing hole and the 3rd installing hole respectively, and the right side extending to rear sealing-plug forms " U " type pipe.
As improvement, described water inlet pipe is provided with breather with the centre of return pipe, and the right-hand member of breather goes directly in cavity through the second installing hole.
Compared with prior art; it is an advantage of the current invention that: sealing-plug before the left part of described inside weld gas shield device cavity is provided with; the right part of described inside weld gas shield device cavity is provided with rear sealing-plug; front sealing-plug forms the cavity of opposing seal with rear sealing-plug; this structure, to guarantee inside weld good sealing effect in production process, inside weld surface-brightening, basic non-oxidation, improves the weldquality of laser welding pipe；Water inlet pipe is connected in " U " type pipe on the right side of rear sealing-plug with return pipe, and is provided with certain interval between water inlet pipe and return pipe, and this structure avoids the direct projection of laser, it is ensured that the normal service life of this device；And " U " type pipe runs through cavity, under the circulating of cooling water, the heat that inside weld (solder joint) produces constantly is discharged, it is to avoid trachea is blown or clogging, meets quantity-produced needs.
Accompanying drawing explanation
Fig. 1 is the front sectional view of the present invention；
Fig. 2 is the left view of the present invention；
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
nullSuch as Fig. 1、Shown in 2，A kind of stainless steel laser welded tube inside weld gas shield device，Including water inlet pipe 1、Return pipe 2、Breather 3 and inside weld gas shield device cavity 4，Inside weld gas shield device cavity 4 is provided with three installing holes，As shown in Figure 2，Installing hole is a straight line and the front sealing-plug surface being distributed in inside weld gas shield device cavity 4 evenly and at intervals，It is followed successively by the first installing hole 5 from top to bottom、Second installing hole 6 and the 3rd installing hole 7，The left part of inside weld gas shield device cavity 4 is provided with front sealing-plug 8，The right part of inside weld gas shield device cavity 4 is then provided with the rear sealing-plug 9 corresponding with front sealing-plug 8，Front sealing-plug 8 and rear sealing-plug 9 form the cavity 10 of opposing seal，Wherein，Water inlet pipe 1 and return pipe 2 run through cavity 10 through the first installing hole 5 and the 3rd installing hole 7 respectively，And the right side extending to sealing-plug 9 forms " U " type pipe，Certain gap it is provided with between water inlet pipe 1 and return pipe 2，This structure avoids the direct projection of laser，Ensure that the normal service life of this device，The centre of water inlet pipe 1 with return pipe 2 is provided with breather 3，Breather 3 goes directly through the second installing hole 6 inside of cavity 10；Water inlet pipe 1 and return pipe 2 have employed the copper tube of highly heat-conductive material, under the circulating of cooling water, constantly discharged by the heat that inside weld (solder joint) produces, it is to avoid trachea is blown or clogging, meets quantity-produced needs；It is provided with certain interval between water inlet pipe 1 and return pipe 2, avoids the direct projection of laser, it is ensured that the normal service life of this device.
In welding process, starting cooling water pump, cooling water is by water inlet pipe 1 by, after inside weld protection device cavity 4, being flowed to cooling water tank by return pipe 2, and the heat in inside weld gas shield device cavity 4 leads to the circulation of supercooled water and takes it out cavity；Breather 3 passes to argon, makes argon form the sealing cavity of an argon in being passed through the cavity 10 of sealing, it is ensured that weld seam is protected by argon to the cooling procedure of cold conditions from hot, it is to avoid the oxidized phenomenon of inside weld.
Certainly the present embodiment with regard to installing hole be a straight line and evenly and at intervals example be described, installing hole may not be in a straight line, and interval can also uneven setting.
