[0002] With the rapid development of China's steel economy, the market demand for steel pipes is increasing continuously, and the requirements for the precision of steel pipes are also rising. Chamfering the edges of the steel pipe end face is an important process in steel pipe forming. The chamfering machine is the most basic equipment in steel pipe chamfering processing. After being processed by the chamfering machine, the steel pipe has high quality and high added value, which can greatly improve the engineering quality.

[0003] In the traditional processing method, the chamfering processing of steel pipes usually relies on manual operation, which requires a large amount of labor and time, and it is difficult to guarantee the precision and quality. The main purpose of this control system is to improve the precision, efficiency and automation degree of chamfering processing, reduce manual operation and labor costs, and at the same time improve production efficiency and product quality.

[0004] This control system can reduce the impact on the environment. The traditional processing method usually generates a large amount of cutting waste and noise, causing certain pollution and harm to the environment. While this system adopts the control method of PLC and frequency converter, which can reduce the generation of waste and the emission of noise, thus reducing the impact on the environment.

[0005] In summary, this control system can improve the processing precision, efficiency and automation degree, and at the same time can also reduce manual operation and environmental impact.
