[0002] In modern high-speed continuous rolling production, the use of loopers, especially cutting loopers, is an indispensable part of the automatic speed control system of the rolling mill. In order to ensure the accuracy of product size, several loopers are usually set in the finishing mill to store a certain amount of loopers under micro-tension in the rolled pieces between adjacent frames, which serves as a buffer when the speeds between frames are not coordinated, thereby eliminating the fluctuation of the dimensional accuracy of the rolled pieces caused by the dynamic speed changes between the frames during the rolling process, and finally achieving micro-tension rolling.

[0003] In the prior art, for example, publication number CN208628127U discloses a multi-wire looper for slitting rolling, including a looper body, the looper body including a body base, a first pressing roller is provided above the rolling track at the inlet of the rolled piece, a movable stand with a second pressing roller and a lifting roller installed is provided on the body base at the outlet of the rolled piece, the rear parts of the two movable base side plates of the movable stand are fixed to the two third bearing seats on the body base through a rotating shaft, a connecting rod is fixed on one side of the movable base, and the other end of the connecting rod is hinged to the end of the piston rod of a cylinder.

[0004] However, in the prior art, when the multi-wire looper is being raised, the overall shape of the device changes, which causes the stress state of the workpiece to change. These changes will have different degrees of impact on the workpiece. When there is a large change in force or the overall stress is uneven, the workpiece will deviate from its normal position, which will directly affect the normal processing of the workpiece. Summary of the invention

[0005] The utility model aims to solve the problem in the prior art that the rolled piece is easy to deviate from the normal position when the multi-wire looper is released, and proposes a deviation-correcting multi-wire looper for high-speed slitting and rolling.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-line looper for correcting high-speed slitting and rolling, comprising a base, one end of the top of the base is fixedly installed with a first pressure roller, the other end of the top of the base is rotatably connected with a bearing platform, and the top of the bearing platform is fixedly installed with a second pressure roller;

[0007] A positioning rod is fixedly installed at the edge of the upper surface of the carrying platform, a rotating rod is rotatably connected to the outer wall of the positioning rod, a transmission rod is fixedly installed on one side of the rotating rod, a calibration plate is slidably connected to the upper surface of the carrying platform, a connecting frame is fixedly installed on one side of the calibration plate, the transmission rod is slidably connected to the inside of the connecting frame, and the calibration plate is located on both sides of the carrying platform.

[0008] Preferably, a guide rod is fixedly mounted on the upper surface of the carrying platform, and the guide rod is slidably connected to the calibration plate.

[0009] Preferably, an inverted triangular piece is fixedly mounted on the lower surface of the bearing platform, and a limiting rod is fixedly connected between the two inverted triangular pieces.

[0010] Preferably, a support seat is fixedly mounted on the upper surface of the base, and the support seat is rotatably connected to the limiting rod.

[0011] Preferably, a limit block is fixedly installed on the upper surface of the base, and one side of the limit block is rotatably connected to a top supporting cylinder.

[0012] Preferably, one end of the carrying platform is rotatably connected to a sleeve-lifting roller.

[0013] Preferably, a docking rod is fixedly mounted on the bottom of the bearing platform, and the end of the piston rod of the supporting cylinder is hinged to the docking rod.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, a calibration plate is arranged on the upper surface of the bearing platform, and the position of the calibration plate is controlled by a rotating rod. When the sleeve is lifted, the calibration plate can be pushed to rotate with the positioning rod as the center. The calibration plate can push the rolled piece that has deviated from the normal position back to the normal position, thereby achieving the purpose of deviation correction. Even if the rolled piece is in a state of uneven force, normal processing can be guaranteed.

[0016] 2. In the utility model, the bearing platform is pushed by the supporting cylinder. When the sleeve is lifted, the bearing platform will rotate with the limiting rod as the center. During the rotation of the bearing platform around the limiting rod, the position of the lifting roller will change, thereby realizing rapid lifting. The calibration plates are located on both sides of the bearing platform and will not affect the normal lifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a multi-line deviation correction looper for high-speed slitting and rolling, including a base 1, a first pressure roller 2 is fixedly installed on one end of the top of the base 1, a carrying platform 3 is rotatably connected to the other end of the top of the base 1, a second pressure roller 4 is fixedly installed on the top of the carrying platform 3, a positioning rod 8 is fixedly installed at the edge of the upper surface of the carrying platform 3, a rotating rod 9 is rotatably connected to the outer wall of the positioning rod 8, a transmission rod 13 is fixedly installed on one side of the rotating rod 9, a calibration plate 10 is slidably connected to the upper surface of the carrying platform 3, a connecting frame 12 is fixedly installed on one side of the calibration plate 10, the transmission rod 13 is slidably connected to the inside of the connecting frame 12, the calibration plate 10 is located on both sides of the carrying platform 3, a guide rod 11 is fixedly installed on the upper surface of the carrying platform 3, the guide rod 11 is slidably connected to the calibration plate 10, and a lifting roller 5 is rotatably connected to one end of the carrying platform 3.

[0025] The specific configuration and function of this embodiment are described in detail below. The base 1 supports the main structure of the entire device. The first pressing roller 2 is located at the inlet of the base 1, and the second pressing roller 4 is located at the outlet of the base 1. When the rolled piece passes through the looper, it first passes under the first pressing roller 2, then passes over the looping roller 5, and then moves to the bearing platform 3, and finally moves out from under the second pressing roller 4 to enter the next process.

[0026] In this process, the carrying platform 3 rotates to use the lifting roller 5 to lift the roll. During the lifting process, if the rolled piece is offset due to uneven force, the rotating rod 9 can be manually pushed to rotate. The rotating rod 9 will rotate with the positioning rod 8 as the center of the circle. During the rotation of the rotating rod 9, the transmission rod 13 will push the calibration plate 10 to move toward the center of the carrying platform 3.

[0027] The transmission rod 13 pushes the calibration plate 10 to push the rolled piece that has deviated from the normal position back to the normal position, thereby achieving the purpose of correction. The existence of the connecting frame 12 provides sufficient space for the transmission rod 13 to ensure that the rotation of the rotating rod 9 can push the calibration plate 10. The guide rod 11 will determine the moving route of the calibration plate 10 to prevent the calibration plate 10 from tilting.

[0028] Embodiment 2: Figure 2 , Figure 3 and Figure 4 As shown, an inverted triangular piece 14 is fixedly installed on the lower surface of the bearing platform 3, and a limiting rod 16 is fixedly connected between the two inverted triangular pieces 14; a supporting seat 15 is fixedly installed on the upper surface of the base 1, and the supporting seat 15 is rotatably connected to the limiting rod 16; a limiting block 6 is fixedly installed on the upper surface of the base 1, and a top supporting cylinder 7 is rotatably connected to one side of the limiting block 6; a docking rod 17 is fixedly installed on the bottom of the bearing platform 3, and the end of the piston rod of the top supporting cylinder 7 is hinged to the docking rod 17.

[0029] The effect achieved by the entire embodiment is that the bearing platform 3 is rotatably installed on the support seat 15 through the limit rod 16. When the sleeve is lifted, the top cylinder 7 pushes the docking rod 17. The electric control switch of the top cylinder 7 is set on the side of the base 1. Since one end of the top cylinder 7 is rotatably connected to the limit block 6, the piston rod is rotatably connected to the docking rod 17. Therefore, when the piston rod in the top cylinder 7 is extended, it will push the bearing platform 3 to rotate around the limit rod 16, thereby completing the sleeve lifting. The limit rod 16 is installed on the inverted triangle piece 14 and has good structural strength.

[0030] The use method and working principle of the device: When the rolled piece passes through the looper, it first passes under the first pressure roller 2, then passes over the lifting roller 5, and then moves to the bearing platform 3, and finally moves out from under the second pressure roller 4 to enter the next process. In this process, the top cylinder 7 pushes the docking rod 17, driving the bearing platform 3 to rotate around the limit rod 16, and the lifting roller 5 is used to complete the lifting;

[0031] If the rolled piece is offset due to uneven force, the rotating rod 9 can be manually pushed to rotate with the positioning rod 8 as the center. The transmission rod 13 located on the side of the rotating rod 9 will push the calibration plate 10 to move toward the center of the supporting platform 3 through the connecting frame 12. The existence of the connecting frame 12 provides sufficient space for the transmission rod 13 to ensure that the rotation of the rotating rod 9 can push the calibration plate 10. After the deviation correction is completed, the calibration plate 10 can be brought back to the initial position by turning back the rotating rod 9.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
