Background technology
In the processing of electric heater product, need many electrothermal tubes to be fixed by flange.The connection processing mode of existing electrothermal tube and flange is: first, electrothermal tube to be placed in the flange hole of flange and to make the outside mouth of pipe of electrothermal tube concordant with the aperture, outside of flange hole, by argon arc welding or Laser Welding, the mouth of pipe of electrothermal tube and flange welding being fixed; Then, brazing solder is penetrated in the gap between flange hole hole wall and electrothermal tube, by soldering, electrothermal tube and flange welding are fixed.The connecting structure of this existing electrothermal tube and flange has the following disadvantages: in the occasion such as turnover, carrying of electric heater product, electrothermal tube and flange are in outside extruding force with under the effect of gravity, should both easily ftracture in Welding position, electrothermal tube electric property is reduced, causes electric heater product in use to produce leaking, risk of leaking electricity.
Utility model content
Technical problem to be solved in the utility model is: the connecting structure providing a kind of electrothermal tube and flange.
Solve the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:
A connecting structure for electrothermal tube and flange, comprises electrothermal tube and flange, it is characterized in that: described connecting structure also comprises metal sleeve, metal sleeve to be sleeved in body outboard end that described electrothermal tube exposes electrode and to be fixed by riveting method, the electrode of described electrothermal tube is made to reach the outer fix of described flange in the flange hole that metal sleeve stretches into described flange, and, the mouth of pipe of described electrothermal tube body outboard end, the mouth of pipe of metal sleeve outboard end is mutually concordant with aperture, the outside three of described flange hole and be welded and fixed by argon arc welding or Laser Welding mode, the outer wall of described electrothermal tube body and the inwall of described metal sleeve are welded and fixed in the mode of soldering by the solder infiltrating this gap between the two, the outer wall of described metal sleeve and the inwall of described flange hole are welded and fixed in the mode of soldering by the solder infiltrating this gap between the two.
For the ease of inwall from the outer wall metal sleeve to electrothermal tube body between gap stretch into solder, as of the present utility model one improve, the medial end of described metal sleeve is provided with breach.
Fix for the ease of the riveted joint between metal sleeve and electrothermal tube body, one as utility model is improved, the medial end of described metal sleeve is provided with the relative described breach in a pair position, and described metal sleeve is fixed by the outboard end of riveting method and described electrothermal tube body on the position of described two breach.
Wherein, described solder is any one in money base soldering paste, copper base soldering paste, Ni-based soldering paste, aluminium base soldering paste, tinbase soldering paste.
Compared with prior art, the utility model has following beneficial effect:
The utility model was by once establishing metal sleeve, effectively can strengthen the bonding strength of electrothermal tube and flange and increase the lifting surface area of electrothermal tube and flange, prevent in turnover carrying, receive external force or from the welding position cracking that the various undesirable elements such as gravity cause, cause the risk of leaking to drop to solder cracking minimum.
