Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing devices, and more specifically, the utility model relates to a clamping and fixing device for steel pipes. Background Technique

[0002] A steel pipe is a steel product with a hollow cross-section, and its length is much greater than the diameter or circumference. Steel pipes are not only used for transporting fluids and powdered solids, exchanging heat energy, manufacturing mechanical parts and containers, but also an economical steel. Using steel pipes to manufacture building structure grids, supports and mechanical brackets can reduce weight, save metal and achieve factory mechanized construction.

[0003] When processing steel pipes, it is necessary to clamp and fix the steel pipes to ensure that the steel pipes do not rotate or move during the processing of the steel pipes, so as to ensure the stable progress of the processing. The existing steel pipe clamping and fixing devices generally use clamps to clamp the steel pipes from the outside of the steel pipes. Although this method can play a basic role in clamping and fixing, because it is clamped from the outside, it is easy to cause scratches, abrasions and even depressions on the outer surface of the steel pipes, seriously affecting the quality of the steel pipes. Therefore, it needs to be improved. Content of the Utility Model
