[0022] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0023] The following embodiments may be understood as a part of a local structure or method that is expressed separately in the present invention, or may be understood as a combination of the embodiments to explain the connotation of a larger structure or method of the present invention.

[0024] Example 1

[0025] An automatic rolling plate for a steel pipe threading machine, such as Figure 5 As shown, it includes a first rolling plate 01 for installation on the side of the main head 07 of the threading machine facing the auxiliary head 06, and a second rolling plate 02 for installation on the side of the auxiliary head 06 facing the main head 07. The first rolling plate 01 and the second rolling plate 02 have the same structural dimensions and are arranged opposite to each other. Figure 1 As shown, the first rolling plate 01 and the second rolling plate 02 both include a plate body 1, the top of the plate body 1 is an inclined surface 2, and the inclined surface 2 is provided with a first groove 3 and a second groove 4 from top to bottom, and a first lifting mechanism and a second lifting mechanism are respectively provided on the outer surface of the plate body 1 and at the lower part of the first groove 3 and the lower part of the second groove 4, and a material blocking mechanism is provided on the outer surface of the plate body between the first groove 3 and the second groove 4, and a guide plate 5 is fixedly connected to the outer end of the plate body 1 and between the first groove 3 and the second groove 4.

[0026] Example 2

[0027] like Figure 1 , 5 As shown, the high end of the inclined surface 2 is used to receive the steel pipe 12 transmitted by the threading machine feeding mechanism, and the low end is used to transport the steel pipe 12 to the threading machine unloading bin 05, and the low end of the inclined surface 2 is chamfered to form an inclined increasing section 6. After the steel pipe 12 is processed, it can fall into a specified position in the unloading bin 05 along the inclined increasing section 6.

[0028] like Figure 1 As shown, the inclined surface 2 between the first groove 3 and the second groove 4 constitutes a transition slope for conveying the cut steel pipe. The material blocking mechanism is arranged on the outer surface of the plate body 1 on the side of the transition slope facing the second groove 4 to block the steel pipe. After the steel pipe stops, the blocking is released, and then the steel pipe can enter the second groove at a lower speed to avoid the steel pipe rushing through the second groove too fast or causing uncontrollable displacement due to too high a speed.

[0029] Example 3

[0030] like Figure 1-3 As shown, the first ejection mechanism comprises a first cylinder 7 and a first ejection plate. The first cylinder 7 is arranged longitudinally. The fixed end of the first cylinder 7 is fixedly connected to the plate body 1. The telescopic end extends upward and is fixedly connected to the first ejection plate (not marked in the figure). The first ejection plate is opposite to the first groove 3. Figure 1 , 4 As shown, after the steel pipe 12 enters the first groove 3, the two ends of the steel pipe can be fixed by a clamp (not shown in the figure, a common structure), and the length of the steel pipe can be cut by a cutting device (not shown in the figure, a common structure), such as Figure 4 As described above, after the cutting is completed, the first cylinder 7 is extended, and the cut steel pipe 12 is pushed out of the first groove 3 through the first ejector plate, and then the first cylinder 7 is reset. It should be noted that the clamp and cutting device mentioned in the present invention are technical structures of other parts of the automatic threading machine and are not within the technical scope of the present invention.

[0031] Example 4

[0032] like Figure 1 , 4 As shown, the second ejection mechanism includes a second cylinder 9 and a second ejection plate 10. The second cylinder 9 is arranged longitudinally, the fixed end of the second cylinder 9 is fixedly connected to the plate body 1, and the telescopic end extends upward and is fixedly connected to the second ejection plate 10. The second ejection plate 10 is opposite to the second groove 4. When the steel pipe is located in the two second grooves, the steel pipe is fixed by a clamp, and the two ends of the steel pipe are threaded through the main head and the auxiliary head. The threaded steel pipe is extended by the second cylinder 9 to eject the second groove 4 and slide into the following hopper 05. In this new model, the main head and the auxiliary head mentioned are the common technical structures of the threading machine, and the contents not mentioned are solved by the existing solutions.

[0033] Example 5

[0034] like Figure 1 , 2 As shown, the first ejector plate and the second ejector plate 10 have the same structure, both including an ejector plate body with the same inclination as the inclined surface (such as Figure 1As shown in the figure, not marked), a stopper plate (such as Figure 1 The purpose is to limit the reverse movement of the steel pipe.

[0035] Example 6

[0036] like Figure 1 , 3 As shown, the material blocking mechanism includes a third cylinder 8, the fixed end of the third cylinder 8 is fixedly connected to the outer surface of the plate body 1, and the piston rod extends upward, and the piston rod is used to form a material blocking component for blocking the steel pipe 12 from descending. The inclined surface between the first groove 3 and the second groove 4 constitutes a transition slope. When the steel pipe is cut, it is ejected from the first groove 3 by the first ejection mechanism and slides downward along the transition slope. In order to prevent the steel pipe 12 from moving too fast, the third cylinder 8 is extended in advance, and the steel pipe 12 is blocked by the piston rod, and then the piston rod is retracted to release the steel pipe 12, and the steel pipe 12 can enter the second groove 4 at a controllable speed.

[0037] Example 7

[0038] like Figure 1-3 As shown, the guide plate 5 comprises a connecting rod 51, a vertical section 52, and an inclined section 53. The two ends of the inner surface of the vertical section 52 are fixedly connected to the outer end surface of the plate body 1 through the connecting rod 51, and the top of the vertical section 52 is integrally formed with an inclined section 53 inclined outward. After the steel pipe is guided out of the first groove 3, it enters between the vertical sections of the two guide plates under the guidance of the inclined section for precise guidance, ensuring that the moving trajectory of the steel pipe after cutting is controllable.

[0039] The use principle of this new model:

[0040] like Figure 4 , 5 As shown, the steel pipe transported from the feeding mechanism enters the high end of the inclined surface 2 and slides into the first groove. After entering the first groove, the two ends of the steel pipe are clamped by the clamp, and then the cutting mechanism cuts the steel pipe into a set size, and then the first ejecting mechanism leads the steel pipe out of the first groove, and the steel pipe slides downward in the transition inclined surface, and the third cylinder extends to prevent the steel pipe from sliding down and consumes the potential energy of the steel pipe sliding down. Then, the third cylinder contracts, and the steel pipe enters the second groove at a slower speed. At this time, the second cylinder has been pre-extended to a certain length, and the steel pipe falls on the second ejecting plate. The second cylinder contracts and slowly places the steel pipe on the clamps on the outside of the first rolling plate and the second rolling plate. Then, the two ends of the steel pipe are clamped by the clamp, and the two ends of the steel pipe are threaded through the main head and the auxiliary head. After the threading is completed, the second ejecting mechanism ejects the steel pipe, and the processed steel pipe slides into the lower silo along the inclined surface.

[0041] The above process of the present invention can be completed by controlling the extension and contraction of the first to third cylinders by a control mechanism. The relevant control principle can be: control by a time module, for example, starting the first cylinder, the second cylinder, or the third cylinder within a set time, or control by a sensor-assisted control mechanism, for example, a visual sensor detects the position of the steel pipe and the cutting or threading state, and then starts the first cylinder, the second cylinder, or the third cylinder. Since the relevant content is not within the technical scope of the present invention, it will not be repeated here.
