Description

Technical Field

[0001] The invention relates to the technical field of a UHV iron tower connection flange, and in particular to an automatic splicing device for a cylindrical transmission iron tower flange. Background Art

[0002] Flanges are suitable for connecting pipe fittings. Flanges are also used in the production of large power towers and communication towers. However, due to the huge size of large towers, their pipe diameters are large, and the inner diameter can even reach more than one meter, so the size of the flange is also correspondingly large, and the thickness of the flange is also thicker, generally more than 20mm. This kind of oversized flange cannot be directly processed due to size reasons. Generally, multiple flange unit plates are cut from steel plates of corresponding thickness, and then the flange unit plates are spliced ​​and fixed in sequence before welding. The welding equipment fully welds the welding grooves between adjacent flange unit plates. Since the thickness of the flange unit plates used to splice the flanges is thicker, the depth of the welding grooves is also deeper, and the amount of solder used is also larger, and a large amount of solder is accumulated in the welding grooves. Because the temperature of the solder is relatively high, when a large amount of high-temperature molten solder accumulates in the welding groove for a period of time, deformation will occur between adjacent flange unit plates, and even high-temperature molten solder will escape from the bottom weld; if deformation occurs, the flange plate will need to be reshaped after welding; if solder escapes from the weld, the escaped solder will need to be cut and polished later, and the strength and hardness of this solder are very high, which makes cutting and polishing very troublesome, and the cost of the solder used for welding this flange plate is also relatively expensive, and the escaped solder will also lead to increased production costs and waste.

[0003] Therefore, the applicant urgently needs to provide a device which is not only convenient for the splicing of flange unit plates, but also can prevent the flange from bending during welding after the splicing, and can prevent the solder from escaping from the weld. Summary of the invention
