Description

Technical Field

[0001] The utility model relates to a looper, in particular to a looper applied to a bar and wire continuous rolling production line, belonging to the technical field of steel rolling production equipment. Background Art

[0002] Steel rolling is the process of changing the shape of ingots and billets between rotating rollers. The purpose of steel rolling is the same as other pressure processing. On the one hand, it is to obtain the required shape. Loopers are often required during steel rolling in steel mills. In the production process of high-speed wire and bar, since the operation of each frame is not exactly the same, such a speed difference will cause the bars between the two frames to be stretched or relaxed, thereby generating tension. This will affect the physical properties and other factors of the wire or bar during processing, resulting in a decrease in product processing quality. In addition, the continuous rolling production lines on the market mainly have single-line, two-cut, three-cut and four-cut production processes. When using different production processes to produce rolled pieces, the corresponding looper needs to be replaced.

[0003] The existing patent discloses a looper device that is convenient for steel rolling operation (publication number: CN214133335U), which discloses a looper device that is convenient for steel rolling operation and relates to the field of steel rolling technology. The application includes a first transmission device, a second transmission device, a connecting device and a control device, and the first transmission device and the second transmission device are both arranged on the top of the connecting device, and the first transmission device and the second transmission device are both fixedly connected to the connecting device. Although the application can make the steel rolling run more smoothly in the looper by setting the connecting device and the control device, so that the looper height remains unchanged at the set value and the speed flow balance between the frames is achieved, the looper of the application is fixedly connected to the sleeve roller, resulting in that the looper cannot be replaced according to different production processes. At the same time, in the application Figure 2 It can be seen that the contact area between the looper and the roller is small, which can easily lead to unstable fixation during use.
