AI Technical Summary
When steel pipes need to be bent in applications, a separate process is often required to adjust the bending angle, which cannot quickly adapt to actual needs, resulting in low efficiency and long cycles.
A bending-adjustable steel pipe is designed. By setting connecting holes at both ends of the steel pipe and connecting them with bending connectors, the corrugated pipe and limit spring provide rebound potential energy, thereby achieving flexible angle adjustment and connection.
It enables flexible adjustment and rapid adaptation of the angle of the steel pipe during use. Through the design of the connector, the efficiency and flexibility of steel pipe bending are improved, and the need for on-site processing is reduced.
