Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a steel pipe fixing and supporting device for steel pipe processing. Background Art

[0002] Steel pipes are used to transport fluids and powdered solids, exchange heat, and manufacture mechanical parts and containers. They are also an economical steel material. Steel pipes have a hollow section and their length is much greater than their diameter or circumference. According to the cross-sectional shape, they are divided into round, square, rectangular and special-shaped steel pipes.

[0003] Through patent search, it was found that a steel pipe fixing support device for steel pipe processing with publication number CN220534035U is designed with a base, a frame, a first clamping ring, a second clamping ring, a first threaded rod, a turntable, a limit hole, a limit rod, a bearing, a connecting plate, a circular cross bar, a groove, a clamping block, a slide groove, a connecting plate, a second threaded rod, a fixed seat, and a swivel, so that the steel pipe can be firmly fixed during the processing process, and the inner wall and the outer wall of the steel pipe can be clamped at the same time, making the fixation more secure. When the steel pipe is processed, there will be no rotation. The above-mentioned comparative document completes the clamping of both sides of the inner wall of the steel pipe through two groups of clamping blocks extended to both sides. The limiting ability of the two-point clamping is weak, and the steel pipe is easy to move. Utility Model Content
