Description

Technical Field

[0001] The utility model relates to the technical field of wire rod rolling mill guides, in particular to a rolling outlet guide for a wire rod rolling mill. Background Art

[0002] In bar and wire rod production lines, especially in roughing and intermediate rolling mills, the distances between rolling mills are long. This causes the head and tail of the rolled piece to rub against the exit guides during movement, resulting in surface scratches. These scratches not only affect the quality of the finished product but can also reduce the yield rate. Surface quality is particularly important when producing high-demand steel grades such as large-scale cold-headed steel and spring steel. Once scratches occur, not only can they cause financial losses, but they can also disrupt production rhythms and reduce efficiency due to downtime required to address the scratches.

[0003] Currently, traditional exit guides rely primarily on sliding friction. While this approach is simple, it can lead to increased wear between the workpiece and the guide in high-speed, heavy-load production environments, further increasing the risk of scratches. Therefore, effectively reducing scratches during the rolling process and improving product surface quality and production efficiency have become urgent technical challenges. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a rolling exit guide for a wire rod rolling mill. By installing rollers on the exit guide, rolling friction is used instead of sliding friction, which significantly reduces the friction between the rolled piece and the guide, thereby effectively solving the above-mentioned problems and improving product quality and production efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides a rolling exit guide for a wire rod rolling mill, comprising:

[0006] A guide body, wherein the guide body is provided with a guide groove for guiding the rolling piece to pass through;

[0007] An outlet rolling assembly, installed at the outlet end of the guide groove, for reducing friction between the rolled piece and the guide groove;

[0008] The outlet rolling assembly includes:

[0009] A roller frame having an L-shaped cross section, one end of which is detachably connected to the outlet end of the guide groove, and the other end of which is located below the rolled piece and protrudes from the guide body to form the L-shape;

[0010] A roller member, the roller member is mounted on the roller frame, and the roller member includes a roller;

[0011] The roller is rotatably connected to the roller frame, the top of the roller is higher than the outlet end of the guide groove, and the roller contacts the workpiece to prevent the workpiece from directly contacting the guide body. Rolling friction replaces sliding friction, reducing scratches on the workpiece during rolling.

[0012] Furthermore, the roller member further includes:

[0013] A shaft body is mounted on the lower end of the roller frame, and the roller is rotatably mounted on the shaft body.

[0014] Furthermore, the roller member further includes:

[0015] At least two bearings are respectively provided at both ends of the shaft body and are used for rotatably connecting the shaft body and the roller.

[0016] Furthermore, screw holes are provided on the left and right sides of the roller frame for installing adjustment screws to adjust the height of the roller frame relative to the roller frame.

[0017] Furthermore, it also includes:

[0018] A cooling water pipe is connected to the roller member to cool the roller.

[0019] Furthermore, it also includes:

[0020] A hanging ring is arranged above the guide body.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) By installing rollers on the exit guide, rolling friction replaces sliding friction, significantly reducing the friction between the workpiece and the guide. This effectively reduces scratches on the workpiece during rolling and improves the surface quality of the workpiece. At the same time, it reduces downtime caused by scratch treatment, thereby improving the continuous operation capacity and production efficiency of the production line.

[0023] (2) The rollers provided in the present invention also reduce the direct contact between the guide body and the rolled piece, thereby reducing the wear of the guide body, extending the service life of the equipment, and reducing maintenance costs.

[0024] (3) The roller frame of the utility model is provided with screw holes for installing adjustment screws. The height of the roller frame can be flexibly adjusted according to actual production conditions to ensure the optimal contact between the roller and the rolled product. It is particularly suitable for the production of large-scale cold heading steel, spring steel and other high-demand steel varieties, effectively ensuring the surface quality of these steels and meeting the needs of different customers. It improves the adaptability of the guide and the convenience of adjustment.

[0025] (4) The utility model can cool the roller through the cooling water pipe, effectively control the roller temperature, prevent the roller from being damaged due to overheating, and further improve the service life and working efficiency of the roller.

[0026] (5) The lifting ring installed above the guide body facilitates the handling and maintenance of the guide, improving the safety and efficiency of on-site operations. By reducing scratches on rolled pieces and material waste, it reduces material waste caused by surface quality problems, improves material utilization, reduces production costs, and improves economic benefits, which has important economic value to the enterprise.
