Start the electrode for being gradually applied to electrolytic industry, the condenser in power station, the heater of petroleum refining and sea water desalination for mid-term
And the general industries manufacturing field such as environment pollution control device.
Currently, titanium alloy seamless pipe rolling in the market is all single pipe Direct Rolling, this pipe is in a section contracting
When at small tubes, small length of tube can satisfy product requirement, but seamless pipe exigent for size makes, such as both
It needs to produce length long, it is also desirable to which the seamless pipe being relatively large in diameter roll using only one section of pipe being difficult to meet to produce and be wanted
It asks, to influence the production of product, is welded at present using the pipe of two or more, then again to whole after welding
Body pipe is rolled, but due to two sections of pipes welding when it is difficult to ensure that two pipes central coaxial, lead to whole pipe
It deforms, influences subsequent rolling work.
Summary of the invention
In order to solve the above-mentioned technical problem the utility model, provides a kind of connection structure of spliced titanium seamless tubes, can
During carrying out pipe splicing, the centering of two pipes is realized using the positioning spigot of two blank ends, and by pipe
One and the end of pipe two be designed to plug in construction, be conducive to the strength and stability for improving whole pipe after being welded,
Be conducive to subsequent rolling work.
The technical scheme adopted by the utility model is a kind of connection structure of spliced titanium seamless tubes, including pipe one
With pipe two, the end face of pipe one is provided with the boss of a circular ring shape on paracentral position, and the end face of pipe two is in
The toroidal cavity of indent is provided on the position of the heart, boss is equal with the outer diameter of groove, in the boss outer circumference surface of pipe one
On be evenly equipped with multiple projections, the two sides of each projection are equipped with groove, are equipped with equal with projection quantity lack in the end face of pipe two
Mouthful, the size of notch and projection it is equal sized.
The boss radial outer edge of the pipe one is equipped with chamfering, and the groove inner diameter edge of pipe two is equipped with chamfering.
The projection upper end-face edge position of the pipe one is provided with chamfering, and chamfering is arranged in the end edge of pipe two.
When work, first the boss on pipe one is cooperated with the groove on pipe two, after achieving the purpose that centering,
Again by the notch of the projection insertion pipe two on pipe one, relatively rotated with limiting pipe one and pipe two, after the completion of docking,
It is fully welded along three sides of projection, and is fully welded in the end chamfer position of pipe two, after the completion of welding, to weld seam
It polishes, so that smooth welded seam, realizes the connection of pipe one and pipe two.
The end face of the pipe one is provided with the boss of a circular ring shape on paracentral position, and the end face of pipe two is close
The toroidal cavity of indent is provided on the position at center, boss is equal with the outer diameter of groove；The purpose being arranged in this way is: passing through
Boss forms seam allowance with groove and connects, and is conducive to the quick centring of pipe one and pipe two, improves the efficiency of work.
Described that multiple projections are evenly equipped on the boss outer circumference surface of pipe one, the two sides of each projection are equipped with groove,
The end face of pipe two is equipped with the notch equal with projection quantity, and the size of notch and the equal sized of projection are set；It is arranged in this way
Purpose is: the docking of pipe one and pipe two, to prevent during the welding process, pipe are completed by the way that projection to be inserted into notch
One and pipe two relatively rotate, it is area in order to increase welding that groove is arranged on projection position, improves the matter of welding
Amount.
The utility model has the following beneficial effects:
The utility model structure is simple, and design rationally, can utilize two pipe ends during carrying out pipe splicing
The positioning spigot in portion realizes the centering of two pipes, and the end of pipe one and pipe two is designed to plug in construction, favorably
In the strength and stability for improving whole pipe after being welded, be conducive to subsequent rolling work.
