AI Technical Summary
In existing technologies, manual coordination is required for loading and unloading during the steel pipe narrowing process, which affects efficiency and poses a danger.
Design a seamless steel pipe necking mechanism, including a feeding unit, a necking unit, a discharging unit and a positioning unit. Utilize a cylinder to drive the positioning plate and baffle to achieve automated positioning, clamping and feeding control of the steel pipe, and combine with a buffer mechanism to achieve fully automatic necking.
The process of narrowing the steel pipe has been fully automated, improving efficiency and safety, ensuring that the steel pipe is placed horizontally and is fixed stably, and avoiding the danger of manual intervention.
