Description

Technical Field

[0001] The present application relates to the technical field of metallurgical equipment, and in particular to a high-tension coiler with a centering function. Background Art

[0002] In conventional rolling mill operations, the gearbox of the coiler must remain fixed to ensure stable tension of the strip during rolling, prevent deviation and distortion, and thus maintain the material thickness tolerance and plate shape stability for easy control. However, if there is a serious deviation in the alignment of the incoming coil edge, the coiler will not be able to correct such problems, which may lead to rolling difficulties, edge cracks, strip breakage, etc., thereby reducing the yield rate, increasing production costs, and possibly damaging the equipment. Usually, in order to solve this problem, it is necessary to add a decoiler or rewinding line in front of the coiler, but this will lead to a significant increase in equipment investment costs.

[0024] The following is a further detailed description of this application in combination with the attached Figures 1-5 drawings.

[0025] The embodiments of this application disclose a large-tension coiler with a centering function.

[0026] Referring to Figures 1-3 , a large-tension coiler with a centering function includes a coiler body 1, a fixed base 2, and a slide plate 3. The slide plate 3 is slidably mounted on the fixed base 2. Specifically, the slide plate 3 is a copper slide plate, and the coiler body 1 is fixedly mounted on the slide plate 3 by bolts to realize the sliding operation of the coiler body 1 on the fixed base 2.

[0027] Furthermore, the coiler body 1 includes a coiler pressure roller, a coiler push plate, a coiler reel support, a coiler input shaft coupling, and a coiler core shaft. In this embodiment, the installation of each component of the coiler body 1 is prior art and will not be elaborated here. The coiler core shaft is used for expansion and contraction operations on the rotary oil cylinder to ensure that necessary large tension is provided during the rolling process to tightly wind the strip being rolled onto the core shaft.

[0028] Referring to Figures 1-5, in a further embodiment, a large-tension coiler with a centering function further includes a coiler gearbox 5, a vertical locking device 6, and a lateral locking device 7. The coiler gearbox 5 is installed on the sliding plate 3 and is power-connected to the coiler body 1, and is used to drive the coiling function and speed adjustment of the coiler, which is prior art and will not be elaborated too much. The vertical locking device 6 and the lateral locking device 7 are installed on the fixed base 2 to limit the sliding of the coiler gearbox 5 and the sliding plate 3 when no centering operation is required, so as to ensure the fixation of the coiler gearbox 5 under high tension. This measure ensures the stability, rigidity, and strength of the coiling device during large-tension rolling operations.

[0029] Further, the vertical locking device 6 includes a mounting plate 61, a first hydraulic cylinder 62, and a first locking seat 63. The mounting plate 61 is fixedly installed on the fixed base 2 by bolts. The first hydraulic cylinder 62 is arranged vertically on the mounting plate 61. The locking seat is sleeved and fixed on the piston rod of the first hydraulic cylinder 62 to slide in the direction of approaching or departing from the coiler gearbox 5, so as to realize the tight limiting of the coiler gearbox 5 in the vertical direction; the lateral locking device 7 includes a second hydraulic cylinder 71 and a pressing block 72. The second hydraulic cylinder 71 is fixedly installed on the fixed base 2 by bolts and the piston rod is arranged towards the side wall of the coiler gearbox 5. The pressing block 72 is fixedly sleeved on the piston rod of the second hydraulic cylinder 71 to slide in the direction of approaching or departing from the coiler gearbox 5, so as to realize the tight limiting of the coiler gearbox 5 in the horizontal direction.

[0030] Referring to Figure 1 and Figure 3 , a large-tension coiler with a centering function further includes a centering moving hydraulic cylinder 8 and a centering hydraulic cylinder moving locking device 9. The centering moving hydraulic cylinder 8 is installed on one side of the fixed base 2 at the tail of the coiler body 1 through a support 10, and the piston rod of the centering moving hydraulic cylinder 8 is fixed to the coiler body 1 to push the coiler body 1 and the sliding plate 3 to slide on the fixed base 2. The centering hydraulic cylinder moving locking device 9 is installed on the support 10 to limit the sliding of the piston rod of the centering moving hydraulic cylinder 8, further ensuring the fixation of the coiler body 1 when no centering operation is required and ensuring the stable operation of the whole coiler.

[0031] Further, a displacement sensor (not shown in the figure) is installed on the fixed base 2 to detect the offset of the edge of the coil. The displacement sensor is signal-connected to the vertical locking device 6, the lateral locking device 7, the centering moving hydraulic cylinder 8, and the centering hydraulic cylinder moving locking device 9, and then controls the centering operation of the coiler body 1 through the detected data.

[0032] Referring to Figure 1In a further embodiment, a plurality of base pressing plates 11 are fixedly installed on the fixed base 2 by bolts, and the plurality of base pressing plates 11 are arranged on both sides of the sliding direction of the sliding plate 3 to limit the sliding of the sliding base.

[0033] The working principle of the utility model of a high tension winder with centering function is as follows:

[0034] When the coiler body 1 is operating normally but not performing the centering function, the servo valve of the centering hydraulic cylinder 8 stops working, and the centering hydraulic cylinder locking device 9 also stops supplying hydraulic oil, causing the centering hydraulic cylinder 8 to be locked in the front-to-back direction and unable to move. At this time, the hydraulic cylinder 1 62 of the vertical locking device 6 and the hydraulic cylinder 2 71 of the lateral locking device 7 on the base will receive hydraulic oil and operate, thereby locking the coiler gearbox 5 in the vertical and tension directions, ensuring the stability of the coiler under high tension.

[0035] When the centering function needs to be performed, the centering hydraulic cylinder moving locking device 9 of the centering moving hydraulic cylinder 8 will be supplied with hydraulic oil to unlock it, and at the same time, hydraulic cylinder 1 62 and hydraulic cylinder 2 71 supply hydraulic oil in reverse to release the lock of the gear box. The servo valve of the centering moving hydraulic cylinder 8 starts to work, so that the coiler body 1 can slide back and forth along the base under the push of the centering moving hydraulic cylinder 8. The displacement sensor device provides feedback closed-loop measurement to correct the offset of the edge of the material roll. The utility model combines mechanical structure and hydraulic technology to achieve fast and convenient operation, while maintaining the simple structure of the equipment and low investment cost, and significantly reduces equipment failures caused by raw material problems, improves the yield rate, and reduces production costs.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
