[0002] Finishing mill is a kind of equipment used for metal material processing, mainly used for precision rolling of metal strips or metal tubes to achieve specific size, shape and surface quality requirements. The spring shaft in the finishing mill usually bears the functions of support and transmission. Turning the spring shaft of the finishing mill is a common processing method, which can achieve the dimensional accuracy and surface quality requirements of the spring shaft.

[0003] The spring shaft of the finishing mill can be put into use only after processing is completed. In the document with patent number CN219853534U, a lathe turning protection device is proposed, including a turning body; the side end of the turning body is fixedly connected to a limiting slide rail; a protection door is slidably connected to the limiting slide rail; the side end of the protection door is fixedly connected to a No. 1 handle; the inside of the protection door is fixedly connected to an observation window; the protection door slides toward the direction of the connecting sealing plate, and the sliding of the connecting block will cause the No. 2 elastic block to slide and contact the No. 1 elastic block. The position of the connecting block can be limited in the connecting card frame through the elastic extrusion of the No. 2 elastic block and the No. 1 elastic block, so that the position of the protection door is limited to the connecting sealing plate. After the protection door slides, it cooperates with the turning body to form a sealed space to avoid chips splashing and accidentally injuring workers during processing. At this time, the turning body can be started for processing, so as to avoid chips splashing and injuring people.
