Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a deformation-preventing and local shaping tool for circular seam welding of a fan-shaped barrel comprises a tool body 1, a platform and a backer structure, wherein the tool body 1 comprises an upper arc plate 2, a lower arc plate 3, a hydraulic ram 4, two connecting rods 5 and handrails 6, the two sides of the upper arc plate 2 and the lower arc plate 3 are fixedly connected, an installation cavity is arranged inside the upper arc plate 2 and the lower arc plate 3, the hydraulic ram 4 is arranged inside the installation cavity, the output end of the hydraulic ram 4 is connected with a jacking block 7, the two connecting rods 5 are arranged, one point of each connecting rod 5 extends into the installation cavity and is fixedly connected, and the other side of each connecting rod 5 is fixedly connected with the corresponding handrail 6;
more specifically, a plurality of fan-shaped barrels are detachably mounted on the outer sides of the upper arc plate 2 and the lower arc plate 3, and gaskets are arranged on the contact surfaces of the upper arc plate 2, the lower arc plate 3 and the fan-shaped barrels;
wherein, the backer structure is fixed platform, and frock body 1 still includes the area of tightening up that is used for tightening up fan-shaped bucket.
The working principle is as follows: when in use, two fan-shaped barrels to be spliced are placed on a platform, then an anti-deformation tool is inserted into the circular seam of the two fan-shaped barrels to be spliced, wherein an upper arc plate 2 and a lower arc plate 3 are respectively arranged at the top side and the bottom side inside the splicing part of the two fan-shaped barrels, then one side of the fan-shaped barrel to be spliced is close to a backer structure to be abutted, the two fan-shaped barrels to be spliced are abutted and tensioned by the backer structure and a tensioning belt, after the two fan-shaped barrels to be spliced which are placed on the platform are placed in a straight line, the hydraulic ram 4 is controlled to work, the hydraulic ram 4 controls the jacking block 7 to eject the position of the welding position to the jacking height which is the anti-deformation height required by welding, then the welding part of the circular seam is welded, and the welding defect and the welding deformation caused by the displacement or deformation of the circular seam are avoided in the welding process, when the circular seams of the two fan-shaped barrels are welded, the welded fan-shaped barrels are placed and cooled, the tool body 1 is forced to be drawn out through the handrail 6 and the connecting rod 5, and then the splicing work of the fan-shaped barrels is completed; the principle is that a fan-shaped barrel tool manufactured by utilizing an internal expansion and contraction structure is utilized;
it should be noted that, when the fan-shaped barrel needs to be spliced for a longer time, the welding is completed in the same way;
the utility model has simple structure, low manufacturing cost and simple operation, and has remarkable effect on circular seam welding and local correction of the sector barrel sheet below 3 mm; the tool greatly improves the circular seam butt welding of the fan-shaped barrel, improves the welding quality and the production efficiency, and reduces welding deformation, welding defects and other problems.
