Description

[Technical field]

[0001] The invention relates to the field of pipe processing equipment, in particular to a pipe feeding mechanism and a high-speed rolling mill. [Background technology]

[0002] When the pipe is rolled, the mill head usually processes and drags the pipe at the same time. The processing speed of the pipe is low. If the mill head exerts a large traction force on the pipe, the quality of the pipe will be affected during the rolling process. In the general processing process, the pipe will be conveyed along the core rod, which guides the conveying of the pipe. To increase the conveying speed of the pipe, it is necessary to avoid contact with the core rod. [Summary of the invention]

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and propose a pipe feeding mechanism to increase the feeding speed of the pipe.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The pipe feeding mechanism includes a frame and slide rails arranged on both sides of the frame. The frame is provided with a top feeding trolley slidably mounted on the slide rails. A core rod for guiding the transmission of the pipe is provided on the frame between the two slide rails. The core rod is located below the top feeding trolley. When the pipe is transmitted on the frame, it is sleeved on the outer periphery of the core rod. A pushing piece is provided at the bottom of the top feeding trolley. The pushing piece is abutted against the end of the pipe to push the pipe to be transmitted along the core rod on the frame.

[0006] Furthermore, the pushing member is provided with a through hole with a diameter larger than that of the core rod, and when the pushing member pushes the tube to move, the through hole is coaxial with the core rod.

[0007] Furthermore, the pushing piece is rotatably mounted on the bottom of the top-feeding trolley, and the pushing piece can be flipped up and down relative to the top-feeding trolley.

[0008] Furthermore, a stopper is provided on the fixing member, and the stopper stops the pushing member from flipping when the pushing member pushes the pipe to move.

[0009] Furthermore, the stopper abuts against the upper end of the pushing member on the side away from the moving direction of the pipe, so that the pushing member remains horizontal when pushing the pipe to move.

[0010] Furthermore, an elastic member for providing elastic restoring force to the pushing member is provided at the bottom of the top feeding trolley.

[0011] Furthermore, the elastic member is a torsion spring arranged at the rotation connection between the pushing member and the top feeding trolley.

[0012] Furthermore, the lower end of the pusher away from the moving direction of the pipe is a rounded structure.

[0013] A high-speed rolling mill comprises the above-mentioned pipe feeding mechanism.

[0014] Beneficial effects of the present invention:

[0015] The present invention proposes a pipe feeding mechanism, which is used to push the pipe to move on the frame and improve the feeding speed. The top feeding trolley pushes the pipe to move by abutting against the end of the pipe through a pushing piece, rather than by clamping the pipe, which can reduce damage to the pipe. In addition, a core rod is also provided on the frame, and the pipe is sleeved on the outside of the core rod during the movement. If the pipe is moved by clamping the pipe, the inner wall of the pipe will contact the core rod to hinder the movement of the pipe and cause wear to the core rod. In the prior art, the transmission of the pipe along the core rod is generally realized by the pipe processing equipment at the front of the frame, and the pipe is pulled to move while being processed. Compared with the prior art, the pipe is pushed to move by the top feeding trolley, which can increase the speed of pipe transmission and improve production efficiency.

[0016] The present invention also provides a high-speed rolling mill, which adopts the above-mentioned pipe feeding mechanism to realize rapid processing of pipes.

[0017] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0030] Reference Figures 1 to 5 The embodiment of the present invention proposes a pipe feeding mechanism, including a frame 100, and slide rails 110 arranged on both sides of the frame 100. The frame 100 is provided with a top feeding trolley 200 slidably installed on the slide rails 110. A core rod 120 for guiding the transmission of the pipe is provided between the two slide rails 110 on the frame 100. The core rod 120 is located below the top feeding trolley 200. When the pipe is transmitted on the frame 100, it is sleeved on the outer periphery of the core rod 120. A pushing piece 210 is provided at the bottom of the top feeding trolley 200. The pushing piece 210 is abutted against the end of the pipe to push the pipe to be transmitted along the core rod 120 on the frame 100.

[0031] The pipe feeding mechanism is used to push the pipe to move on the frame 100 and increase the feeding speed. The top delivery trolley 200 pushes the pipe to move by abutting against the end of the pipe through the pushing piece 210, rather than by clamping the pipe, which can reduce damage to the pipe. In addition, a core rod 120 is also provided on the frame 100. The pipe is sleeved on the outside of the core rod 120 during the movement. If the pipe is moved by clamping the pipe, the inner wall of the pipe will contact the core rod 120 to hinder the movement of the pipe and cause wear on the core rod 120. In the prior art, the transmission of the pipe along the core rod 120 is generally achieved by the pipe processing equipment at the front of the frame 100, and the pipe is pulled to move while being processed. Compared with the prior art, the pipe is pushed to move by the top delivery trolley 200, which can increase the speed of pipe transmission and improve production efficiency.

[0032] In order to increase the contact area between the pusher 210 and the pipe so that the movement of the pipe can proceed stably, a through hole 211 is provided on the pusher 210, and its actual shape is a sleeve. When the pipe is pushed to move, the through hole 211 is coaxial with the core rod 120, and the diameter of the through hole 211 is larger than the diameter of the core rod 120. In this way, when the top delivery trolley 200 pushes the pipe to move, the pusher 210 can be offset against the circumference of the end of the pipe, and the core rod 120 passes through the through hole 211 of the sleeve, thereby not affecting the movement of the pusher 210.

[0033] During the process of processing the pipe, the pipe needs to be moved to the periphery of the core rod 120 first, and the pusher 210 will block the pipe from moving toward the core rod 120. For this purpose, the pusher 210 has the function of being able to flip up and down relative to the top delivery trolley 200. The pusher 210 is arranged at the bottom of the top delivery trolley 200 and rotates with the top delivery trolley 200. When the pipe moves toward the core rod 120, the pipe can contact the pusher 210 to push the pusher 210 to flip upward, and the pusher 210 will not block the pipe.

[0034] As the pipe moves onto the core rod 120, when the push piece 210 lacks the support of the pipe below, it flips downward and resets. At this time, the top delivery trolley 200 starts to move. The through hole 211 inside the push piece 210 is coaxial with the core rod 120. Therefore, as the top delivery trolley 200 moves, the core rod 120 can be inserted into the through hole 211. As the top delivery trolley 200 continues to move, the push piece 210 can push the pipe to move. During the movement, the reaction force of the pipe on the push piece 210 will make the push piece 210 tend to flip upward. The core rod 120 will block the push piece 210, but the edge of the through hole 211 in the push piece 210 will scratch the core rod 120, and the contact area between the push piece 210 and the pipe is small, which is not conducive to the top feeding of the pipe. Moreover, if the core rod 120 has not yet emerged from the end of the pipe after the power that pushes the pipe to the core rod 120 is used, when the push piece 210 contacts the pipe, the push piece 210 may not be able to push the pipe to move and may even flip in the opposite direction. For this reason, a stopper 220 that can stop the push piece 210 from flipping is provided on the fixing part.

[0035] The stopper 220 will not block the pusher 210 from flipping upward when the tube moves toward the core rod 120, but will block the tube from flipping in the direction opposite to the moving direction of the top feed trolley 200 when the pusher 210 contacts the tube, so as to keep the pusher 210 in full contact with the end of the tube without touching the core rod 120.

[0036] Figures 3 to 5 middle, Figure 3 , the pipe has passed through or has not passed through the pushing member 210; Figure 4 , the pipe is passing through the pushing member 210; Figure 5 In the embodiment, the pipe has passed through the pushing member 210 .

[0037] Reference Figures 2 to 5 Based on the above embodiment, in another embodiment of the present invention, the structure and setting position of the stopper are specifically described:

[0038] Specifically, the stopper 220 is a block-shaped piece protruding from the pushing piece 210. When the pushing piece 210 flips downward to be coaxial with the core rod 120, it contacts the stopper 220, preventing the pushing piece 210 from continuing to flip, so as to stop the pushing piece 210 when pushing the pipe to move. The stopper 220 abuts against the upper end of the pushing piece 210 on the side away from the moving direction of the pipe. If it abuts against the side of the pushing piece 210, it will prevent the pushing piece 210 from flipping to a position coaxial with the core rod 120 during the flipping process of the pushing piece 210. Therefore, it is more appropriate for the stopper 220 to limit the position by abutting against the upper end of the pushing piece 210.

[0039] The tube pushes the push piece to flip upward during the process of moving toward the core rod. When the tube moves out from under the push piece, if the push piece is not flipped downward in time, it may cause the push piece to fail to contact the tube when the top feeding trolley moves. For this reason, in another embodiment of the present invention, an elastic member is provided at the bottom of the top feeding trolley to provide elastic restoring force for the push piece. The elastic member is a torsion spring (not shown in the figure) arranged at the rotating connection between the push piece and the top feeding trolley. The setting of the torsion spring will not take up much space and can quickly restore the position of the push piece.

[0040] Reference Figures 2 to 5 In order to reduce wear, in another embodiment of the present invention, the lower end of the pusher 210 away from the moving direction of the tube is a rounded structure 212. When the tube moves onto the core rod 120, it will push the pusher 210 to flip upward. At this time, the tube will contact the pusher 210 during the continuous movement. The part where the tube contacts the pusher 210 is the lower end of the pusher 210 away from the moving direction of the tube. The rounded structure 212 here can reduce the wear on the surface of the tube.

[0041] The present invention also provides a high-speed rolling mill, comprising the above-mentioned pipe feeding mechanism, which can enable the pipe to move quickly on the high-speed rolling mill, thereby realizing rapid processing of the pipe.

Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
