Description

Technical Field

[0001] The invention relates to the technical field of metal hose welding processing, in particular to an automatic ring welding machine for a metal hose. Background Art

[0002] The bellows is a metal hose. Before use, the bellows in the prior art needs to be covered with a metal mesh sleeve on the outer surface, and then the ends of the bellows and the metal mesh sleeve are placed together in a metal head end and fixed. The fixing method is usually welding, and then subsequent use is performed after welding.

[0003] The welding of metal hoses in the prior art usually requires manual work by workers. However, manual welding has large errors and poor welding effects. Therefore, there are currently some automatic ring welding machines to achieve automatic or semi-automatic welding of corrugated pipes and metal head ends.

[0004] A Chinese patent with authorization announcement number CN110449708A discloses an automatic ring welding machine for a metal hose; a Chinese patent with authorization announcement number CN114393355A discloses a metal corrugated hose ring seam welding device, both of which have good effects on the welding of metal hoses. However, the above patents also have common shortcomings: since a clamping device is required to clamp the metal hose, the metal hose needs to be continuously rotated during ring welding to complete the welding process. However, during the welding process, there is a certain possibility that the rotation angles of the metal hose and the metal joint are inconsistent, especially when the rotation angles of the metal hose and the metal joint are inconsistent after some points have been welded, it is easy to cause a large welding error, resulting in poor welding effect.

[0005] Therefore, we propose a metal hose automatic ring welding machine to solve the above problems.
