Description

Technical Field

[0001] The utility model relates to the technical field of welded pipe shaping and straightening, in particular to an adjustable welded pipe shaping and straightening device. Background Art

[0002] Welded pipe is a device used to connect and fix metal pipes, usually made of metal materials. Welded pipes are usually used in industrial and construction fields to connect different pipeline components, such as pipe elbows, pipe flanges, pipe sleeve joints, etc. Welded pipes have the characteristics of high strength, good corrosion resistance and good sealing.

[0003] Welded pipes are widely used in the oil and gas industry, construction and structural engineering, automobile and vehicle manufacturing, machinery manufacturing and equipment manufacturing, marine engineering and shipbuilding, mining and metallurgical industries. Since the shape of welded pipes may become irregular or deformed due to various reasons during the manufacturing and transportation process, a shaping and straightening device is needed to correct the shape of the welded pipe to meet the specified requirements, and also to ensure the correct and firm connection of the welded pipe. For example, the Chinese utility model patent with patent publication number CN218555212U includes a fixed seat and a fixed box, both sides of the fixed seat are slidably connected to a mounting block, the upper surface of the mounting block is connected to a straightening roller assembly, and the straightening roller assembly includes a fixed screw shaft fixedly connected to the upper surface of the mounting block, and the top end of the fixed screw shaft is spirally sleeved with a screw barrel.

[0004] Although this patent can adjust the wheel length of the straightening roller according to the different diameters of the welded pipe through the design of the straightening roller assembly, so that welded pipes of different diameters can contact the wheel surface of the roller without being affected by the roller flange, so as to avoid the roller flange from adversely affecting the straightening and shaping of the welded pipe. However, when adjusting the wheel length of the straightening roller, the staff is required to rotate multiple cross-rotating parts in sequence, which not only makes the adjustment process cumbersome and time-consuming, but also the individual adjustment of each straightening roller makes it difficult to ensure that the wheel length of all rollers is consistent, which may cause the flanges of some rollers to contact the welded pipe, resulting in certain inconveniences in actual use. In view of this, we propose an adjustable welded pipe shaping and straightening device. Utility Model Content

Through the above structure, the spacing between all the upper half wheels and the lower half wheels can still be synchronously adjusted after the displacement block moves, and it is also more convenient to adjust the spacing of the displacement blocks.
