Description
Technical Field
[0001] The utility model belongs to the technical field of welding, and in particular relates to a splash-proof device for a welded pipe fly-cutting trolley. Background Art
[0002] Steel pipes are used for conveying fluids and powdered solids, exchanging heat, and manufacturing mechanical parts and containers. Steel pipes can be divided into two categories based on their production method: seamless steel pipes and seamed steel pipes. Seamed steel pipes are divided into straight seam steel pipes and spiral welded pipes. Spiral welded pipes are made by rolling low-carbon structural steel or low-alloy structural steel strips into a tube blank at a specific spiral angle and then welding the spiral seams. Currently, welded pipe production generally involves batch production on a production line. During production, a fly-cutting trolley is used to cut the pipe to the specified size based on the intended use. During the cutting process, in order to improve the cutting efficiency, a cutting device is provided on the flying cutting trolley. The cutting device often adopts a plasma cutting gun. The plasma cutting gun is used to cut the welded pipe. Plasma cutting penetrates the steel pipe through an instantaneous high-voltage arc. The high temperature generated melts the welded pipe to achieve the cutting of the welded pipe. It has the advantages of fast cutting speed and smooth cutting surface. However, during the cutting process, high-temperature molten iron will fall. The high-temperature molten iron falls on the inner wall of the welded pipe. After cooling, it will adhere to the inner wall of the welded pipe. After the cutting is completed, splashes of solidified molten iron will appear on the inner wall of the welded pipe, seriously affecting the cleanliness and surface quality of the inner wall. The inner wall of the welded pipe needs to be ground to remove the splashes, which leads to an increase in the number of processes, an increase in time consumption, an increase in labor intensity, and a reduction in production efficiency.
