Description

Technical Field

[0001] The utility model relates to the technical field of sizing machines, in particular to a double-station steel pipe mechanical sizing machine. Background Art

[0002] The working principle of the mechanical sizing machine is that the motor drives the driving roller to drive the sizing rod forward or backward (the sizing gauge and the sizing rod are connected by threads), so that the sizing gauge passes through the pipe body to achieve the purpose of detecting the straightness and roundness of the steel pipe. Compared with the dynamic sizing machine, the mechanical sizing machine has reliable power, simple structure, and is intuitive and convenient to judge whether the sizing is qualified. However, due to the limited driving speed, the movement speed of the sizing rod is generally less than 2m / s, and the working efficiency is low, which has become one of the bottleneck equipment restricting the entire steel pipe inspection production line.

[0003] The existing double-station mechanical diameter gauge for steel pipes, when in use, fixes the steel pipe in only one direction, which may result in loose fixation and easily lead to loosening of the steel pipe, thus affecting the measurement results.

The utility model has reasonable design, convenient use, high production efficiency, low cost, reliable power, stable operation, high product quality and good application prospects.

[0005] Although the above patent is easy to use, has high production efficiency, low cost, reliable power, stable operation, high product quality and good application prospects; however, the device lacks the function of cleaning the inside of the pipeline. Dirt, accumulation or impurities may adhere to the inside of the pipeline, which will affect the final measurement results and cause measurement errors.
