The linkage structure of domestic each bellows is more complicated all, influences the large batch of production of bellows, the especially existing metal bellows that is welded to connect; Domestic title welding type metallic bellows predominant use is that equipment needs vacuum environment or the vibration isolation environment is arranged, also or special air bound leave, also be applied to semiconductor equipment, optical equipment, vacuum precision instrument, gas outlet means, analytical instrument, nuclear energy often and close attached device, accelerator, medical equipment, inspection equipment etc.; The present domestic manufacturing technology of still not having; Generally weld maintenance at home by external inlet hose, but because when welding between bellows and the joint, it is inhomogeneous that it causes welding to dissolve easily; Sealing is poor; Structure is comparatively complicated, and it is high that inconvenience, engineering cost and defect rate are installed, and influences the working life of bellows pulling force contractibility and bellows.
The model utility content
To the deficiency that exists on the existing technology; The utility model purpose provides a kind of welding to dissolve uniformity consistency, connection is stable, quick and easy for installation and maintenance cost is low clamp flange welding type bellows; It is safe and reliable, guarantees bellows pulling force contractibility and improves the quality yield.
To achieve these goals, the utility model is to realize through following technological scheme:
Clamp flange welding type bellows, it comprises bellows, the connecting end at bellows two ends and the clamp flange that is connected with connecting end is set, and it is characterized in that; Said connecting end is a straight tube; End at said straight tube is provided with the welding step, connects described clamp flange on its other end, and the seam crossing of said clamp flange and straight tube is welded as a whole through argon arc welding; Be provided with Ka Tai and the interior circular groove that is used to connect straight tube the other end end in said clamp flange inboard; One end end of said clamp flange is provided with outer annular groove, increases bonding area, makes its welding dissolve uniformity consistency.
Above-mentioned a kind of bellows linkage structure, wherein, the thickness of said bellows is 0.15-0.20mm.
Above-mentioned a kind of bellows linkage structure wherein, also is provided with groove on the surface of said clamp flange, this groove is as the lap joint flange locating point position.
Above-mentioned a kind of bellows linkage structure wherein, also is provided with circular groove on the surface of said welding step.
Above-mentioned a kind of bellows linkage structure wherein, also is provided with outer annular groove on the other end end of said clamp flange.
The utility model passes through the clamp flange is connected, and through the argon arc welding welding, welding dissolves uniformity consistency when welding, increases its bellows pulling force contraction, and yield improves the quality; And have that whole erection is convenient and swift, safe and reliable, maintenance cost is low, connection is firm and the advantage of long service life, and increase the soundness of welding and avoid because of welding causes the suction surface amount of deformation, be fit to produce in batches.
Description of drawings
Specify the utility model below in conjunction with accompanying drawing and embodiment;
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the partial structurtes schematic representation of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, a kind of clamp flange welding type bellows of present embodiment, it comprises bellows 1, the connecting end at bellows 1 two ends and the clamp flange 4 that is connected with connecting end is set, and this 1 thick end of bellows is 0.15-0.20mm, and length is 136mm.The connecting end of present embodiment is a straight tube 3, is provided with welding step 2 at an end of straight tube 3, and this welding step 2 is provided with the port position of straight tube 3; Its thickness is 5mm; On the madial wall of welding step 2, be processed with and be welded to connect Ka Tai, and the outer surface of welding step 2 is processed with small-sized circular groove 21, the slot cross-section semicircular in shape of this circular groove 21 near the position of welding step 2 one ports with straight tube 3; Its radius is 0.5mm; This circular groove 21 is 0.3mm with welding step 2 one ports distance, plays and strengthens welding step 2 intensity, increases the soundness of welding tin bar.
At straight tube 3 the other ends is to connect clamp flange 4 on the outer end, and what this clamp flange 4 adopted is DN160 clamp flange 4, and its length is 15mm; Side is processed with the Ka Tai that is used to connect straight tube 3 the other end ends within it; During welding, straight tube 3 is inserted in the clamp flange 4, and keep out on Ka Tai straight tube 3 the other end ends; Be welded as a whole through argon arc welding at the seam crossing of clamp flange 4, make it safe and reliable with straight tube 3.
