Abstract
The invention discloses a single-side welding forming welding tool. The single-side welding double-side forming welding tool comprises a guide rail vehicle (2) which can run in a to-be-welded steel tube (1), a material groove (3) is formed in the guide rail vehicle (2), asbestos cloth (5) used for containing a submerged-arc welding agent (4) is arranged in the material groove (3), and a tracheal cushion (6) is arranged between the bottom of the asbestos cloth (5) and the bottom of the material groove (3). After the guide rail vehicle (2) enters the to-be-welded steel tube (1), before welding is prepared to be conducted, the tracheal cushion (6) is inflated, the asbestos cloth (5) used for containing the submerged-arc welding agent (4) is jacked to make the submerged-arc welding agent (4) be attached to a welding seam formed in the upper portion of the to-be-welded steel tube (1), during welding, the submerged-arc welding agent (4) is attached to the welding seam all the time, the submerged-arc welding agent (4) overflows from inside to outside along the welding seam, and therefore double-side welding of the to-be-welded steel tube (1) is completed at the same time. The problem that inside and outside welding of the welding seam is not synchronous is solved, the production efficiency and the welding quality are greatly improved, and the single-side welding forming welding tool is suitable for being popularized.

The object of the invention is for prior art Problems existing, provide a kind of can the single-side welding double-side forming welding tooling of out-seam in synchronous welding.
The object of the invention is to solve by the following technical programs:
A kind of single-side welding double-side forming welding tooling, comprising can at the guide rail car treating to walk in Coiling Welded Pipe, it is characterized in that: described guide rail car is placed with hopper, the asbestos cloth of splendid attire submerged arc welding flux is provided with in hopper, and trachea pad is provided with between the bottom and the bottom land of hopper of asbestos cloth, when guide rail car enter after Coiling Welded Pipe prepare welding before, the asbestos cloth of trachea pad inflation jack-up splendid attire submerged arc welding flux makes submerged arc welding flux press close to weld seam above it, during welding, submerged arc welding flux againsts weld seam all the time and makes submerged arc welding flux overflow from the inside to the outside along weld seam and then complete the two-sided welding treating Coiling Welded Pipe simultaneously.
Described hopper comprises outer hopper and interior hopper, and interior hopper to be placed in outer hopper and to be provided with lower trachea pad between outer hopper and interior hopper, and is provided with trachea pad between the bottom of asbestos cloth and the bottom land of interior hopper.
Described guide rail car comprises places the support platform of hopper, and the channel-section steel below support platform is provided with roller shaft, and the two ends of roller shaft are respectively equipped with roller, and roller can the guide rail below guide rail car run also can treating to run in Coiling Welded Pipe.
Described roller is arranged on roller shaft by bearing.
The present invention has the following advantages compared to existing technology:
The present invention presses close to the weld seam above it by trachea pad support submerged arc welding flux, during welding, submerged arc welding flux againsts weld seam all the time and makes submerged arc welding flux overflow from the inside to the outside along weld seam and then complete the two-sided welding treating Coiling Welded Pipe simultaneously, solve the nonsynchronous problem of external welding in weld seam, greatly improve the uniformity of commissure welding stress; Descend in addition trachea pad and upper trachea pad and outer hopper and interior hopper with the use of, further ensure submerged arc welding flux and fit tightly in commissure, improve welding effect; This welding tooling structure is simple, application is convenient, greatly improves production efficiency and welding quality, is suitable for promoting the use of.
