Description

Technical Field

[0001] The invention relates to the technical field of steel rolling processing, and in particular to a finishing roller uniform wear regulating device. Background Art

[0002] Cold rolled steel strip is made of hot rolled coils and rolled at room temperature below the recrystallization temperature. It includes steel plates and steel coils. The steel plates delivered in sheets are called steel plates, also called box plates or flat plates; the steel strips delivered in long lengths and in coils are called steel coils, also called coils.

[0003] The steel strip rolled in the cold rolling mill has different widths depending on the product and raw material specifications, but the steel strips of different widths on the cold rolling mill generally enter and are fully rolled from the center of the roller, which inevitably leads to uneven wear in the middle and on both sides of the roller. This uneven wear of the roller, when severe, will form a concave step surface in the middle of the roller. This phenomenon is generally not taken seriously during rough rolling or rolling of some products with low precision requirements, but it has a particularly prominent impact on the product during the finishing rolling of ultra-thin (less than 0.3mm) steel strips (called ultra-thin precision steel strips in the industry). Summary of the invention

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a finishing roller uniform wear control device, which can effectively prevent uneven wear of the roller, thereby improving the finishing quality of ultra-thin steel strips.

The push rod can be slidably inserted in the through hole, and one end of the push rod is fixedly connected to the guide plate, one end of the connecting rod is hinged to the eccentric shaft, and the other end is hinged to the push rod. When the rotating power source drives the rotating disk to rotate, the guide block can be pushed to slide along the first sliding groove through the connecting rod and the push rod.

[0013] Furthermore, the eccentric shaft is movably connected to the rotating disk, and the eccentric shaft can be fixed in the radial direction of the rotating disk.

[0014] Furthermore, a T-shaped third slide groove with a larger bottom and a smaller top is opened along the radial direction of the rotating disk. The eccentric shaft includes a rod body, a pressure plate and a locking nut. The bottom end of the rod body can be slidably inserted in the third slide groove. The pressure plate is arranged at the bottom end of the rod body and is located in the large end of the third slide groove. The locking nut is sleeved on the rod body and threadedly connected with the rod body. By rotating the locking nut, the locking nut can be pressed tightly on the surface of the rotating disk and drive the pressure plate to be pressed tightly on the interface between the large end and the small section of the third slide groove.

[0015] Furthermore, it also includes a lifting structure, which is connected to the frame of the cold rolling equipment on which the rolling roller is installed and to both ends of the rotating shaft of the rolling roller.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the invention is not limited by the specific implementation disclosed below.

[0033] See also Figures 1 to 7 The present invention provides a finishing roller uniform wear regulating device, including a fixing structure 100, a guide structure 200 and a transverse linear motion driving member 300.

[0034] Specifically, the fixed structure 100 is disposed between the roller 2 and the unwinding roller 3 and is located on the conveying line of the steel strip. The guide structure 200 is disposed on the fixed structure 100 and can move in the axial direction parallel to the roller 2, and the steel strip can slide through the guide structure 200. The transverse linear motion driving member 300 is connected to the guide structure 200 and is used to drive the guide structure 200 to move in the axial direction parallel to the roller 2 on the fixed structure 100.

[0035] When in use, the material is first discharged through the discharge roller 3 to make the steel strip between the discharge roller 3 and the rolling roller 2 in a relaxed state, and then the rolling roller 2 and the transverse linear motion drive member 300 are started. During the process of the rolling roller 2 pressing multiple steel strips, the transverse linear motion drive member 300 drives the guide structure 200 to move in the axial direction parallel to the rolling roller 2.

[0036] By adopting the above-mentioned finishing roller uniform wear regulating device, when the steel strip is finish-rolled, since the steel strip moves in the axial direction of the roller 2, it can be avoided that the steel strip is fixed in the center position of the roller 2, thereby avoiding the occurrence of uneven wear of the middle part of the roller 2 relative to the two sides, thereby ensuring the finishing effect of the ultra-thin steel strip.

[0037] Specifically, the guide structure 200 includes a guide plate 210 and a stopper 220. The fixed structure 100 is provided with a first slide groove parallel to the axial direction of the roller, and the transverse linear motion driving member 300 is connected to the guide plate 210. The bottom end of the guide plate 210 can be slidably clamped in the first slide groove. There are two stoppers 220, which are arranged on the guide plate 210 at intervals in the axial direction of the roller 2, and the steel strip can slide through between the two stoppers 220.

[0038] In a specific implementation, balls may be provided on the surface of the guide plate 210 and the inner side surface of the limiting member 220 to facilitate the sliding of the steel belt.

[0039] As a preferred embodiment, the distance between the two limiting members 220 is adjustable to accommodate steel strips of different widths.

[0040] Specifically, the limiting member 220 includes a limiting plate 221. A second slide groove is provided on the guide plate 210, and the bottom ends of the two limiting plates 221 can be slidably engaged in the second slide groove. A double-headed screw 222 is provided between the two limiting plates 221. The threads at both ends of the double-headed screw 222 are rotated in opposite directions. The two limiting plates 221 are respectively threadedly connected to the two ends of the double-headed screw 222. When in use, the two limiting plates 221 can be driven to move closer to each other or away from each other by rotating the double-headed screw 222.

[0041] In this embodiment, the transverse linear motion driving member 300 includes a rotary power source 310, a rotating disk 320, an eccentric shaft 330, a connecting rod 340, a guide block 350 and a push rod 360. The rotary power source 310 is used to drive the rotating disk 320 to rotate. The eccentric shaft 330 is arranged on the rotating disk 320 and is eccentrically arranged relative to the central axis of the rotating disk 320. The guide block 350 is fixedly arranged. A through hole parallel to the roller 2 is opened on the guide block 350, and the push rod 360 can be slidably inserted in the through hole, and one end of the push rod 360 is fixedly connected to the guide plate 210. One end of the connecting rod 340 is hinged to the eccentric shaft 330, and the other end is hinged to the push rod 360. When the rotary power source 310 drives the rotating disk 320 to rotate, the guide block 350 can be pushed to slide along the first slide groove through the connecting rod 340 and the push rod 360.

[0042] When the rotary power source 310 is started, the rotary disk 320 is driven to rotate, and the guide plate 210 can be pushed in the axial direction parallel to the roller 2 through the eccentric shaft 330 , the connecting rod 340 , the guide block 350 and the push rod 360 .

[0043] In this way, in specific implementation, the frequency of the reciprocating motion of the guide plate 210 can be controlled by simply controlling the speed of the rotation power source 310. In addition, the rotation power source 310 can preferably rotate intermittently, such as pausing once every 90° rotation.

[0044] As a more preferred embodiment, in specific implementation, the eccentric shaft 330 can be movably connected to the rotating disk 320, and the eccentric shaft 330 can be fixed in the radial direction of the rotating disk 320. In this way, the span of the left and right reciprocating motion of the guide plate 210 can be controlled according to the width of different steel belts. When the steel belt is wider, the left and right reciprocating span should be small; on the contrary, when the steel belt is narrower, the left and right reciprocating span can be large.

[0045] Specifically, a third T-shaped chute with a larger bottom and a smaller top is provided on the surface of the rotating disk 320 along its radial direction. The eccentric shaft 330 includes a rod body 331, a pressure plate 332 and a locking nut 333. The bottom end of the rod body 331 can be slidably inserted into the third chute. The pressure plate 332 is arranged at the bottom end of the rod body 331 and is located in the large end of the third chute. The locking nut 333 is sleeved on the rod body 331 and is threadedly connected to the rod body 331. By rotating the locking nut 333, the locking nut 333 can be pressed against the surface of the rotating disk 320, and drive the pressure plate 332 to be pressed against the interface between the large end and the small section of the third chute.

[0046] When in use, it is necessary to loosen the locking nut 333 and push the rod body 331 to slide along the third slide. When the target position is reached, the locking nut 333 is used to lock it.

[0047] As a more preferred embodiment, the device further includes a lifting structure 400. The lifting structure 400 is mounted on the frame 1 of the cold rolling equipment where the roller 2 is installed, and is connected to both ends of the rotating shaft of the roller 2, and can lift the roller 2 when the lateral linear motion driving member 300 drives the guide structure 200 to move, and can drive the roller 2 to reset when the guide structure 200 is stationary. In this way, it is possible to avoid lateral pulling of the steel strip due to the compression and limiting of the roller 2 when the guide structure 200 drives the steel strip to move.

[0048] Specifically, the lifting structure 400 includes a mounting block 410, an elastic tensioning member 420 and an electromagnet 430. There are two mounting blocks 410, and a fourth slide groove perpendicular to the bottom surface is set on the left and right sides of the frame 1. The two mounting blocks 410 can be installed in the fourth slide groove so as to slide up and down. The two ends of the roller 2 are rotatably connected to the mounting block 410. The mounting block 410 is a magnetic metal block, and the elastic tensioning member 420 is connected to each mounting block 410, and presses the mounting block 410 vertically downward on the bottom surface of the fourth slide groove. The electromagnet 430 is set below the mounting block 410. When the electromagnet 430 is energized, the electromagnet 430 generates an upward magnetic thrust on the mounting block 410 that is greater than the pressure of the elastic tensioning member 420.

[0049] When there is no need to lift, under the action of the elastic tensioning member 420, the roller 2 is pressed against the steel strip for compression. When it is necessary to lift, the electromagnet 430 is energized, and the electromagnet 430 lifts the mounting block 410 through the magnetic thrust between it and the mounting block 410, thereby separating the roller 2 from the steel strip.

[0050] In this embodiment, the lifting structure 400 further includes a power control member 440. The power control member 440 includes a pressure rod 441. There are four pressure rods 441, and the rotary power source 310 is a rotary motor. The four pressure rods 441 are evenly spaced in the circumferential direction and arranged on the rotating shaft of the rotary motor. When the rotary power source 310 rotates, the four pressure rods 441 can sequentially press on the switch 442 of the electromagnet 430 to put the electromagnet 430 in a power-on state.

[0051] In this way, it can be ensured that the frequency of pushing the guide plate 210 is synchronized with the lifting frequency of the roller 2.

[0052] The usage of the above-mentioned uniform wear control device for the finishing roller 2 is as follows:

[0053] When in use, the material is first discharged through the discharge roller 3 to make the steel strip between the discharge roller 3 and the rolling roller 2 in a relaxed state, and then the rolling roller 2 and the rotating power source 310 are started. While the rolling roller 2 is pressing the steel strip, the guide plate 210 moves back and forth horizontally to avoid feeding the steel strip in the center of the rolling roller 2 where the steel strip is fixed, thereby avoiding the occurrence of uneven wear of the middle part of the rolling roller 2 relative to the two sides, thereby achieving the finishing effect of the ultra-thin steel strip.

[0054] In addition, by lifting the structure 400, the rollers 2 are lifted up in the gap during the rolling process, which can reduce the shear force on the steel strip during the lateral movement, thereby avoiding damage to the steel strip.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
