Technical Field

[0001] The utility model relates to the technical field of pre-cutting of bearing steel pipes, in particular to a pre-cutting device for bearing steel pipes. Background Art

[0002] Bearing steel tubes are mainly used to manufacture rolling elements and rings of rolling bearings. During the processing of bearing steel tubes, the bearing steel tubes need to be cut according to a certain width. The cutting accuracy directly affects the quality of subsequent finished products. Steel tube pre-cutting refers to cutting the steel tube into the required length or shape according to specific requirements before further processing or use.

[0003] After searching, the applicant found that a Chinese patent disclosed "a pre-cutting device for bearing steel tubes", and its publication (announcement) number is "CN217020354U". This patent mainly uses a cutting gun to carve cutting lines on the outer wall of the bearing steel tube, replacing the manual method of mechanically carving cutting lines, which reduces the labor intensity of operators to a certain extent. However, it cannot quickly carve cutting lines at any position on the outer wall of the bearing steel tube. For this reason, we propose a pre-cutting device for bearing steel tubes.
