[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-2 As shown, the steel pipe mouth processing device of this embodiment includes a workbench 1, a support frame 2, a hydraulic cylinder 3 and a necking assembly 4. A fixed plate 5 is also installed on the workbench 1, and a motor 6 is installed on the fixed plate 5. Two rotating rollers 7 are rotatably installed between the support frame 2 and the fixed plate 5, and grooves 8 are provided on the outer walls of the two rotating rollers 7 for mutual use. The rotating rollers 7 can clamp and transport the steel pipe in cooperation with the grooves 8. The motor 6 is connected to the rotating rollers 7 in a transmission manner. A through groove 9 is provided on the workbench 1, and the through groove 9 is located between the support frame 2 and the fixed plate 5. A storage groove 10 is provided on one side above the rotating roller 7, and the storage groove 10 is used to store steel pipes adapted to the storage groove 10. The discharge port at the bottom of the storage groove 10 is used in cooperation with the groove 8.

[0021] Furthermore, a rubber pad 11 is provided on the inner wall of the groove 8 to ensure the stability of the steel pipe fixation.

[0022] Further, a guide blanking plate 12 is provided below the through slot 9 to guide the blanking of the steel pipe after processing.

[0023] Furthermore, a buffer pad 13 is provided on the guide blanking plate 12 to reduce the noise generated by the collision between the steel pipe and the guide blanking plate 12 during blanking.

[0024] Working principle: The steel pipes adapted to the storage trough 10 are placed in the storage trough 10, and the steel pipes are evenly arranged in the storage trough 10. During the process of the motor 6 driving the rotating roller 7 to rotate, the groove 8 on the outer wall of the rotating roller 7 can receive the steel pipe at the discharge port of the storage trough 10. During the continuous rotation of the rotating roller 7, the two grooves 8 used in conjunction with each other approach each other to clamp and fix the steel pipe. At this time, the steel pipe is fixed in the processing position of the necking component 4, and the hydraulic cylinder 3 drives the necking component 4 to process the steel pipe. After the processing is completed, the rotating roller 7 continues to rotate. During the rotation, the gap between the two grooves 8 used in conjunction with each other increases, and the steel pipe falls from the through groove 9 to the guide discharge plate 12, and is guided for discharge through the guide discharge plate 12.
