Product Description
The box column is welded by four steel plates. The manufacturing process is roughly the same as that of welding H-shaped steel. The process is shown in the flow chart.
The box-shaped column is blanked using a CNC flame cutting machine to cut the column plate. The beveling method is carbon arc gouging to cut a K-shaped groove. After the blanking is completed, it is straightened and corrected. In order to ensure that the column body plate is assembled accurately, an assembly tire needs to be prepared. Membrane, the assembly sequence is: first, the upper cover plate is used as the basis, then the assembly line of the diaphragm and side web plates is released, and the U-shaped assembly is carried out. Finally, the lower cover is assembled and welded after the assembly is completed. The main body of the column is welded by submerged arc automatic welding. , the stiffening plate is welded manually with an electric welding machine, and the last partition plate is welded by electroslag pressure welding, and an arc ignition plate is provided for welding. The production and assembly of box columns is the key. The assembly process is as follows:
1. First, the upper cover plate is used as the assembly reference. On the assembly surface, the partition and side web assembly lines are laid out according to the requirements of the construction drawing, and marked with sample punches.
2. First assemble the upper cover and partition, and assemble them on the tire mold. After assembly, welding must be completed before proceeding to the next process.
3. Before assembling the web, the straightness of the web must be checked. During assembly, assemble in one direction. Position the middle stiffening plate first and then the web.
4． The overall assembly of the box structure is carried out after the U-shaped structure is completed. First, correct the edge of the web of the U-shaped structure to make the unevenness <L/1000. Then release the web assembly positioning line on the lower cover plate, flip it over and match the U-shaped structure. The structure is assembled in one direction, and the positioning spot welding adopts symmetrical welding method.
5. The last side of the partition is welded by electroslag pressure welding using special equipment.
