Abstract
The utility model relates to a thin-walled stainless steel pipeline socket argon arc welding connecting structure, comprising a socket. The utility model is characterized in that the end part of the socket is provided with a groove the cross-section of which is rectangular trapezoidal. The utility model absorbs the fusion welding process characteristics of argon gas shielded arc which is formed bya seamed thin-walled stainless steel pipe (the wall thickness is from 0.6mm to 1.5mm) in a roll-welded mode and uses the differences of geometric shapes to increase the strength of heat welding partsand reduce the welding skill requirements. The utility model has the advantages of increasing the thickness of the heat welding parts, enhancing the tensile strength of the heat welding parts and reducing the welding skill requirements.
Description
Technical field
The utility model relates to a kind of thin-walled stainless steel tube socket joint argon arc welding linkage structure, is used for carrying the connection of the thin-walled stainless steel tube of hot and cold water etc., low-pressure fluid, belongs to thin-walled stainless steel tube socket joint argon arc welding linkage structure technical field.
Background technique
Traditional thin-walled stainless steel tube socket joint argon arc welding linkage structure adopts the spigot and socket type argon arc welding to connect between pipe fitting and tubing.As shown in Figure 1, pipe fitting mouth end expansion bellmouth position (abbreviation bellmouth) 1 plays the role of positioning, being manufactured with width A in the end of bellmouth 1 is that 0.5mm～1.5mm, thickness B are the flat shape ring groove 2 of 0.3mm～0.6mm, during welding, directly groove 2 fusings with bellmouth 1 end are welded together with tubing 4 outer walls.Because welding position 3 thickness have only 0.3～0.6mm, so the tensile strength at this position is low, become the weak spot of the withstand voltage and resistance to deformation of pipe-line system; Simultaneously welding is had relatively high expectations, melt trickling easily, further minimizing connects thickness, causes uneven thickness, and also easy through welding tubing causes pipe material inner wall to produce the welding knurl.
The model utility content
The purpose of this utility model provides a kind of tensile strength that strengthens the welding position and reduces thin-walled stainless steel tube socket joint argon arc welding linkage structure to the requirement of welding technical ability.
In order to achieve the above object, the technical solution of the utility model has provided a kind of thin-walled stainless steel tube socket joint argon arc welding linkage structure, comprises bellmouth, it is characterized in that, is provided with at right angles trapezoidal groove of cross section in the end of bellmouth.
Further, the mouth end thickness E of groove is 0.3mm～0.8mm, and the hypotenuse angle [alpha] is 15 °～30 °.
The utility model is drawn the seam thin-wall stainless steel, and (wall thickness is that 0.6mm～1.5mm) volume is welded into the argon arc join by fusion process characteristic of type, utilizes the difference of geometrical shape, realizes strengthening welding position intensity, reduces the requirement of welding technical ability.
The utility model has the advantages that: increase the thickness at welding position, the tensile strength at enhancing welding position and reduction are to the requirement of welding technical ability.

Specify the utility model below in conjunction with embodiment.
Embodiment
Shown in Fig. 2 A and Fig. 2 B, the schematic representation of a kind of thin-walled stainless steel tube socket joint argon arc welding linkage structure that provides for the utility model comprises bellmouth 7, is provided with the groove 5 of cross section at right angles trapezoidal (promptly vertical is trapezoidal) on one side in the end of bellmouth 7.According to pipe fitting 4 wall thickness T is 0.8mm～2.0mm, hold thickness E to be designed to 0.3mm～0.8mm in mouth, the hypotenuse angle [alpha] in cross section is designed to 15 °～30 °, compares with Yuanping City's shape ring groove 2 shapes among Fig. 1, the welding position 6 after argon arc welding connects is thickened and is extended.Pipe fitting bellmouth 7 internal diameters and supporting tubing 4 external diameters are designed to little Spielpassung, can carry out socket joint with tubing 4 and be connected.Pipe fitting be adopt 0.8mm～2.0mm thick seam thin-wall stainless steel pipe manufacturer arranged, the good plasticity of utilizing stainless steel to have adopts the cold extruding technique moulding, the agent structure that makes pipe fitting is an integral body, has reliable withstand voltage properties.During welding, directly with 5 fusings of pipe fitting bellmouth 7 end grooves, be welded together with tubing 4 outer walls, welding position 6 intensity have been strengthened, fusing trickling and the phenomenons such as thin-wall pipes that easy through welding is connected easily reduced the requirement of welding technical ability, the soldering reliability height when having avoided Yuanping City's shape to encircle the groove welding, withstand voltage properties improves, and tensile strength increases.
The utility model is mainly reflected in bellmouth end groove 5 shapes of various angle elbow, tee union as shown in Figure 4 and serial socket joint argon arc welding formula stainless steel pipes such as reducer fitting as shown in Figure 5 as shown in Figure 3.
Concrete production process of the present utility model is as follows:
At first, the raw material Stainless Steel Tube is cut into pipe.Subsequently, cold extrusion shapedly on hydraulic press go out the main pipe body structure.Annealing, enlarging shaping and turning go out each female end groove 5 shape again, carry out surface treatment at last.
