Description

Technical Field

[0001] This utility model relates to the field of steel pipe production technology, specifically a clamping mechanism for steel pipe production. Background Technology

[0002] Steel pipes are steel materials with hollow cross sections, whose length is much greater than their diameter or circumference. According to the cross-sectional shape, they are divided into round, square, rectangular and irregular steel pipes. In factories, it is often necessary to process round steel pipes of the same batch, such as cutting, drilling and polishing. The steel pipes need to be clamped to prevent them from moving and affecting the processing effect.

[0003] According to Chinese Utility Model Application No. 202321719374.X, a steel pipe end clamping device for CNC machining is proposed. The utility model describes that "this steel pipe end clamping device for CNC machining, in order to better clamp steel pipes of different lengths, is equipped with a moving mechanism. When the handle is rotated, it works with a U-shaped frame and a bidirectional threaded rod to allow two threaded blocks to move in opposite directions, thereby changing the relative distance between the two rectangular blocks. This, in conjunction with the clamping assembly, can clamp the ends of steel pipes of different lengths. While the threaded blocks are moving, the connecting rod causes the sliding sleeve to slide on the outer wall of the sliding column, which makes the movement of the rectangular blocks more stable."

[0004] This CNC machining steel pipe end clamping device involves rotating a handle to move two rectangular blocks relative to each other, clamping the steel pipe. A knob is also turned to move a top rubber block downwards, which, in conjunction with the bottom rubber block, clamps the steel pipe. However, when continuously machining circular steel pipes of the same diameter, the clamping speed is slow, affecting processing efficiency. Therefore, an improvement is needed. This paper proposes a clamping mechanism for steel pipe production to solve the aforementioned problem. Utility Model Content
