Abstract
The utility model discloses a kind of servicing unit of aluminum pipe butt welding, comprise lining ring and a stretching block of an open annular, the outer peripheral face of this lining ring coordinates with aluminum pipe inwall, the width of this lining ring is greater than the width of the weld seam of aluminum pipe butt welding, this lining ring is fixed with in two ends of opening part the block extended in lining ring respectively, the inner side free end of two pieces of blocks is drawn close gradually, described stretching block is installed on lining ring described in stretching between described two blocks, and the lateral surface of this stretching block coordinates with the inwall of aluminum pipe.This servicing unit can be installed on aluminum pipe weld bond inwall when butt welding aluminium tube, form weld seam backing plate, servicing unit and aluminum pipe docking location together constitute the welding space of bottom lock, thus the liquid aluminium in welding process molten bath can not flow into aluminum pipe inwall, force shaping, the weld seam of formation without subsiding, the shaping defect such as bad of overlap, root.
Description
Technical field
The utility model relates to a kind of servicing unit, refers to a kind of servicing unit of aluminum pipe butt welding especially.
Background technology
Al and Alalloy has strong oxidability, very easily be combined with oxygen in atmosphere and generate fine and close solid Al2O3, in welding process, aluminum oxide film can hinder intermetallic good combination and easily form slag inclusion, oxide-film also can adsorption moisture, and weld seam can be impelled during welding to generate pore.AC aluminium argon arc welding is the ideal welding method being applicable to the welding of aluminium process pipe.So because aluminum pipe material is special, the mobility of liquid aluminium is large, therefore, when aluminum pipe butt welding, because the flowing of liquid aluminium easily causes the defect such as Welding bead subsidence, overlap.
Utility model content
Technical problem to be solved in the utility model is: the servicing unit providing a kind of aluminum pipe butt welding, this servicing unit can be installed on aluminum pipe weld bond inwall when butt welding aluminium tube, form weld seam backing plate, servicing unit and aluminum pipe docking location together constitute the welding space of bottom lock, thus the liquid aluminium in welding process molten bath can not flow into aluminum pipe inwall, force shaping, the weld seam of formation without subsiding, the shaping defect such as bad of overlap, root.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of servicing unit of aluminum pipe butt welding, comprise lining ring and a stretching block of an open annular, the outer peripheral face of this lining ring coordinates with aluminum pipe inwall, the width of this lining ring is greater than the width of the weld seam of aluminum pipe butt welding, this lining ring is fixed with in two ends of opening part the block extended in lining ring respectively, the inner side free end of two pieces of blocks is drawn close gradually, described stretching block is installed on lining ring described in stretching between described two blocks, and the lateral surface of this stretching block coordinates with the inwall of aluminum pipe.
As the preferred scheme of one, one end of described stretching block is insertion end, the other end is stretching end, this stretching block is increased gradually to stretching end size by insertion end on lining ring width, and the distance of the spacing of one end two link stopper that described block inserts at the stretching block of lining ring width is greater than the spacing of one end two link stopper that stretching block is inserted out.
As the preferred scheme of one, described stretching block lateral surface width is greater than the width of stretching block medial surface.
As the preferred scheme of one, the lateral surface of described stretching block is arc surface, the radius of this arc surface identical with the radius of lining ring and, the outer peripheral face of this arc surface and lining ring forms a face of cylinder jointly.
As the preferred scheme of one, the seamed edge of described stretching block and the equal rounding of wedge angle.
After have employed technique scheme, effect of the present utility model is: the lining ring of this servicing unit puts into aluminum pipe inside, the outer peripheral face of lining ring and aluminum pipe interior contact, when stretching block is inserted from the gap between two blocks of lining ring just by lining ring stretching in aluminum pipe, like this, liquid aluminium during welding in molten bath would not drip, avoid occurring Welding bead subsidence phenomenon, and the inner side free end of two pieces of blocks is drawn close gradually, like this, two blocks will apply outside power to stretching block, thus achieve self-locking, guarantee that the lateral surface of stretching block and aluminum pipe inwall are adjacent to.
Again because one end of described stretching block is insertion end, the other end is stretching end, this stretching block is increased gradually to stretching end size by insertion end on lining ring width, the distance of the spacing of one end two link stopper that described block inserts at the stretching block of lining ring width is greater than the spacing of one end two link stopper that stretching block is inserted out, like this, stretching block is not only subject to the active force of the outside side of block, but also is subject to the clamping force of block, thus makes self-locking effect reach best.
Again because the lateral surface of described stretching block is arc surface, the radius of this arc surface identical with the radius of lining ring and, the outer peripheral face of this arc surface and lining ring forms a face of cylinder jointly.Like this, this outer arc face can coincide with aluminum pipe endoporus radian, thus stretching auxiliaring effect is better.
Again due to seamed edge and the equal rounding of wedge angle of described stretching block, stretching block is avoided to scratch aluminum pipe inwall.

Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail.
As shown in Figure 1, 2, 3, a kind of servicing unit of aluminum pipe butt welding, comprise lining ring 1 and a stretching block 2 of an open annular, the outer peripheral face of this lining ring 1 coordinates with aluminum pipe inwall, the width of this lining ring 1 is greater than the width of the weld seam of aluminum pipe butt welding, this lining ring 1 is fixed with the block 3 extended in lining ring 1 respectively in two ends of opening part, the inner side free end A of two pieces of blocks 3 draws close mutually, described stretching block 2 is installed on lining ring 1 described in stretching between described two blocks 3, and the lateral surface E of this stretching block 2 coordinates with the inwall of aluminum pipe.Above-mentioned lining ring 1, stretching block 2 and block 3 are stainless steel.
One end of described stretching block 2 is insertion end B, the other end is stretching end C, this stretching block 2 is increased gradually to stretching end C size by insertion end B on lining ring 1 width, and the distance of the spacing of one end two link stopper that described block 3 inserts at the stretching block 2 of lining ring 1 width is greater than the spacing of one end two link stopper that stretching block is inserted out.That is block 3 is less than the spacing of the adjacent other end in one end spacing corresponding with another block 3 near one end of insertion end B.
Described stretching block 2 lateral surface E width is greater than the width of stretching block 2 medial surface D, wherein lateral surface E can be plane, can be also arc surface, during for arc surface, the radius of this arc surface identical with the radius of lining ring 1 and, the outer peripheral face of this arc surface and lining ring 1 forms a face of cylinder jointly.The seamed edge of described stretching block 2 and the equal rounding of wedge angle.Can avoid after rounding scratching aluminum pipe inwall, certainly, the stretching block 2 of non-rounding during the stretching block 2 represented in the present embodiment figure, this stretching block 2 also just can solve technical problem of the present utility model.
