Through the elastic support of the elastic clamping mechanism and the support of the inner core rod, the metal tube can be stably transmitted, and through the further clamping action of the clamping roller and the driving roller on the inner core rod, and through the further clamping action of the clamping hydraulic cylinder and the clamping roller, the cold-rolled metal tube is stably supported, so that the transmission stability is better.

[0004] However, when the existing tube rolling mill produces and processes steel tubes, although multiple steel tubes can be dropped into the conveying rail in sequence by setting an inclined plate, when the steel tubes are pushed in the conveying rail, the correction traction between the steel tubes and the receiving holes at the tube rolling mill is not high. When the steel tubes are pushed in the track, friction and vibration may easily cause the steel tubes to deviate, affecting the conveying accuracy of the steel tubes passing through the receiving holes of the tube rolling mill, affecting the conveying efficiency of the tube rolling mill for the steel tubes, and the stable intermittent feeding of the clip type at the conveying port is not high, which does not meet people's use needs.
