[0002] The metal pipe continuous casting liquid replenishment enhanced flow guide system is an advanced continuous casting technology. It improves the liquid replenishment effect of metal pipes in the continuous casting process through a specially designed liquid replenishment structure. This system usually includes a melting mechanism, a heat preservation mechanism, a support mechanism and a continuous casting liquid replenishment forming mechanism. The melting mechanism is responsible for melting the molten metal and conveying it to the heat preservation mechanism. The heat preservation mechanism keeps the molten metal warm and conveys it to the continuous casting liquid replenishment forming mechanism. The continuous casting liquid replenishment forming mechanism performs enhanced liquid replenishment operation on the pipe during the continuous casting process of the pipe to obtain high-quality continuous casting and formed pipes. Liquid replenishment during continuous casting of metal pipes refers to the operation of replenishing liquid metal to the pipes during the continuous casting process of metal pipes to ensure that the pipes can obtain uniform metal replenishment during the solidification process and prevent the pipes from breaking or cracking due to insufficient liquid metal. When replenishing liquid to the metal tube during the drawing process, if a traditional fixed guide system is used, some challenges will be faced. Since the metal tube needs to rotate continuously during the drawing process to maintain the consistency of its shape and structure, the fixed replenishment system is difficult to adapt to the replenishment needs of the rotating tube, which will make it impossible to accurately control the replenishment position and affect the uniformity and accuracy of the replenishment effect.

[0013] Method for using the metal pipe continuous casting liquid replenishment enhanced flow guide system, S1: When the metal tube is replenished with liquid during the drawing process, the metal tube is inside the first rotation limit assembly and the second rotation limit assembly, and the gear drives the inner empty turntable to rotate through the meshing rack, and the inner empty turntable is connected to the inner side of the arc limit groove opened in the chassis through the limit ring, and drives the liquid storage assembly and the liquid replenishment assembly to rotate as a whole when the inner empty turntable rotates. When the liquid storage assembly rotates at the lower end, there is a certain distance between it and the chassis, and when the liquid storage assembly rotates at the upper end, it is inside the upper machine. By controlling the speed of the gear main shaft, the rotation speed of the liquid storage assembly driven by the inner empty turntable is controlled, and the first servo motor, the electric telescopic rod and the hydraulic rod are controlled to keep the rotation speed of the liquid storage assembly consistent with that of the metal tube, and the solid shell plate drives the liquid storage cylinder shell to move, and the liquid storage cylinder shell belt The internal device is driven to move as a whole, and the liquid storage cylinder shell slides on the inner side of the outer fixed plate. When the syringe is inside the notch of the metal tube, the hydraulic rod contracts multiple times to control the extension length of the electric telescopic rod, so that the syringe remains inside the notch of the metal tube. When the hydraulic rod contracts, the inner groove connecting piece is driven to move toward the inside of the liquid storage cylinder shell. The movement of the inner groove connecting piece drives the limited telescopic rod fixed on one side to contract. The movement of the inner groove connecting piece drives the syringe fixed on the inner side to move. The syringe slides inside the liquid storage column groove opened in the solid shell plate. The outer side of the third flexible graphite ring fits with the inner side of the liquid storage column groove opened in the liquid storage cylinder shell. After being squeezed by the syringe, the liquid inside the liquid storage column groove enters the liquid flow guide groove, enters the outer diffuse hole from the liquid flow guide groove, and then flows into the inside of the metal tube notch. S2: When the liquid is filled into the liquid storage cylinder shell, the rotation of the inner empty turntable is controlled by the first servo motor.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the first rotation limit assembly, the liquid storage assembly and the liquid replenishing assembly are provided to realize the precise control of the liquid replenishing process of the metal tube, ensure that the liquid replenishing process is carried out synchronously with the drawing speed of the metal tube, reduce manual intervention, and ensure production safety. Specifically, the structural design that the inner empty turntable drives the liquid storage assembly to rotate as a whole, and the hydraulic rod contracts to drive the inner groove connecting piece to move inside the liquid storage cylinder shell, realizes the operation of precise liquid replenishing of the metal tube, and at the same time, ensures the uniformity and accuracy of the liquid replenishing, and improves the quality of the continuous casting pipe; 2. In the present invention, by providing the feeding assembly, the cone plug and the second spring, the device facilitates the filling of the liquid storage assembly with the supplementary liquid, so that the supplementary liquid can move with the liquid storage assembly, avoiding the traditional fixed guide system. At the same time, when the liquid storage assembly is filled with the supplementary liquid, the sealing performance can be ensured to prevent the supplementary liquid from overflowing and causing harm to the staff; 3. In the present invention, by setting a position adjustment component, a first rotation limit component and a second rotation limit component, the fixed diversion system is set up with a main standby to prevent the device from shutting down after the replenishing liquid inside the liquid storage component is used up, which neither affects the filling of the replenishing liquid nor affects the work of continuously replenishing the metal tube.

[0021] Working process: when replenishing the metal tube during the drawing process, during the drawing process, the metal tube is inside the first rotation limit assembly 5 and the second rotation limit assembly 6, the first servo motor 22 is started to drive the gear 23 to rotate, the gear 23 drives the inner empty turntable 51 to rotate through the meshing rack 53, the inner empty turntable 51 is connected to the inner side of the arc limit groove 24 opened in the chassis 21 through the limit ring 52, which plays a role in limiting the rotation direction of the inner empty turntable 51, and when the inner empty turntable 51 rotates, the liquid storage assembly 7 and the liquid replenishment assembly 8 are driven to rotate as a whole, when the liquid storage assembly 7 rotates the lower end, there is a certain distance between it and the chassis 21, and when the liquid storage assembly 7 rotates the upper end, it is inside the upper machine table 32, which can be To avoid collision between the liquid storage component 7 and the chassis 21 and the upper machine table 32, the rotation speed of the inner idle turntable 51 to drive the liquid storage component 7 is controlled by controlling the rotation speed of the main shaft of the gear 23, and the gap of the metal tube is detected by the existing gap laser detection device. The first servo motor 22, the electric telescopic rod 72 and the hydraulic rod 85 are controlled by the integrated controller 1 to keep the rotation speed of the liquid storage component 7 consistent with that of the metal tube. The electric telescopic rod 72 is started to drive the solid shell plate 71 to move, and the solid shell plate 71 drives the liquid storage cylinder shell 74 to move. The liquid storage cylinder shell 74 drives the internal device to move as a whole. The liquid storage cylinder shell 74 slides on the inner side of the outer fixed plate 73. When the syringe 81 is inside the gap of the metal tube, the hydraulic rod is started. The rod 85 contracts, and the hydraulic rod 85 contracts a lot to control how long the electric telescopic rod 72 extends, so that the syringe 81 remains inside the gap of the metal tube. When the hydraulic rod 85 contracts, it drives the inner groove connecting piece 87 to move toward the inside of the liquid storage cylinder shell 74. The movement of the inner groove connecting piece 87 drives the limited telescopic rod 86 fixed on one side to contract. The limited telescopic rod 86 can improve the stability of the inner groove connecting piece 87 when it moves. The movement of the inner groove connecting piece 87 drives the syringe 81 fixed on the inside to move.

When the inner empty turntable 51 drives the liquid storage component 7 to rotate as a whole, the liquid in the liquid storage column groove 75 is concentrated in the inner part close to the cone plug 78 under the action of centrifugal force. A layer of flexible graphite is arranged on the outer side of the cone plug 78, so as to achieve accurate liquid replenishment of the metal tube and facilitate the control of the uniformity of liquid replenishment. When the liquid storage cylinder shell 74 is filled with liquid, the rotation of the inner empty turntable 51 is controlled by the first servo motor 22. When the liquid storage assembly 7 is at the uppermost end of the inner empty turntable 51, the electric telescopic rod 72 is started to extend. The electric telescopic rod 72 drives the liquid storage cylinder shell 74 to move upward through the solid shell plate 71. When the second flexible graphite ring 76 contacts the first flexible graphite ring 43, the top end of the cone plug 78 contacts the bottom end of the solid cone block 48. Under the push of the cone plug 78, the cone plug 78 moves downward, and the cone plug 78 squeezes the second spring 79. The second spring 79 plays a role in resetting the cone plug 78. At the same time, the solid cone block 48 moves upward, the solid cone block 48 presses the first spring 47, and the first spring 47 plays a role in resetting the solid cone block 48. The solid cone block 48 is slidably connected to the inner side of the square slide 44 opened in the inner hollow shell 41, and plays a role in limiting the moving direction of the solid cone block 48. At this time, there is a gap between the solid cone block 48 and the guide groove 42 opened in the inner hollow shell 41, and there is a gap between the cone plug 78 and the liquid storage column groove 75 opened in the liquid storage cylinder shell 74. The liquid inside the melting box 37 enters the inside of the liquid storage cylinder shell 74 from the guide groove 42, completing the filling of the supplementary liquid, and at the same time ensuring that the supplementary liquid will not overflow; When the replenishing liquid passes through the liquid storage component 7 without delaying the device from replenishing the liquid to the metal tube, during the process of filling the replenishing liquid inside the liquid storage component 7, the second servo motor 33 is started to drive the threaded rotating rod 34 to rotate, and the threaded rotating rod 34 drives the internal threaded plate 36 spirally connected on the outside to move, and the internal threaded plate 36 moves through the melting box 37 to drive the internal straight hole plate 38 to move, and the inner side of the internal straight hole plate 38 is slidably connected to the outer side of the limiting sliding column 35, which plays a role in limiting the moving direction of the melting box 37. When the blanking component 4 fixed at the bottom end of the melting box 37 moves to the liquid storage component 7 installed on one side of the first rotation limiting component 5 or the liquid storage component 7 installed on one side of the second rotation limiting component 6, the liquid can be replenished to the other liquid storage component 7, and the metal tube is continuously replenished with liquid through the first rotation limiting component 5 or the second rotation limiting component 6 corresponding to the liquid storage component 7 filled with liquid, thereby not affecting the filling of the replenishing liquid, and not affecting the work of continuously replenishing the liquid to the metal tube.
