Description

Technical Field

[0001] The utility model relates to the technical field of welded pipe processing, in particular to a welded pipe bending machine which is convenient to move. Background Technique

[0002] Welded steel pipes refer to steel pipes with seams on the surface, which are formed by bending steel strips or steel plates into shapes such as circles and squares and then welding them. The blanks used for welded steel pipes are steel plates or strip steels. Furnace welded pipes can be used as water and gas pipes, etc. Large-diameter straight seam welded pipes are used for high-pressure oil and gas transmission, etc. During the process of processing welded steel pipes, a welded pipe bending machine is needed to perform bending treatment on them.

[0003] However, the existing welded pipe bending machines have the following disadvantages:

[0004] (1) For the existing welded pipe bending machines, the adjustment function is weak. When in use, since the bending angle of the welded pipe needs to be adjusted, the bending angle of the existing bending machine is generally fixed during the use process. When the bending angle needs to be changed, the operator needs to use disassembly tools to disassemble the whole device and then readjust and install it, which is likely to cause the problem of prolonging the bending processing time of the welded pipe.

[0005] (2) For the existing welded pipe bending machines, the moving function is weak. When in use, since the general welded pipe bending machine has a large volume, during the use process, it is necessary to move the processed welded pipe to the processing position. When the number of processed welded pipes is large, it is necessary to hire multiple handling personnel to move the whole device to a suitable position, which is likely to cause the problem of increasing the moving cost of the whole device.
