[0001] This utility model relates to the field of steel processing technology, and specifically provides a steel conveying device. Background Technology
[0002] In the steel production process, grooving roller conveyors are installed between rolling mills according to the rolling process requirements. In existing technology, the steel and the grooving rollers are in sliding contact, which easily scratches the steel surface. After the next rolling pass, this results in steel burrs, making it difficult for quality inspectors to detect internal defects with the naked eye. This negatively impacts product quality and, in severe cases, leads to product scrap.
[0003] Accordingly, there is a need in the field for a new steel conveying device to solve the above-mentioned technical problems. Utility Model Content
[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that existing rolling mills easily scratch steel during the conveying of steel.
[0005] This utility model provides a steel conveying device for conveying steel between rolling mills, the conveying device comprising:
[0006] A workbench, the top surface of which forms a support surface for supporting steel materials during transport;
[0007] Two rows of roller shaft assemblies are provided on the support surface, and each roller shaft assembly in each row is arranged along a first direction; each roller shaft assembly includes a positioning shaft, a conveying roller, a bearing assembly, and a fixing assembly. The conveying roller is sleeved on the outside of the positioning shaft through the bearing, and the fixing assembly is used to position the bearing assembly and the positioning shaft; the centerline of the positioning shaft is perpendicular to the support surface; the roller surface of the conveying roller in the two rows of roller shaft assemblies cooperates with the support surface to form a steel conveying groove for defining the steel conveying direction, and the circumferential surface of each conveying roller is used for rolling friction cooperation with the side of the conveyed steel.
[0008] Based on the above configuration, this steel anti-scratch device significantly reduces surface scratches on steel during transportation by implementing rolling friction instead of sliding friction.

[0014] Based on the above configuration, the fixing assembly includes a washer and a retaining ring. The washer is located between the retaining ring and the second bearing, effectively protecting the second bearing and preventing it from being damaged by direct force. The retaining ring is positioned on the upper side of the first bearing, limiting the top of the first bearing and preventing bearing displacement, thus improving the reliability and durability of the entire device.
[0015] In the preferred technical solution of the above-mentioned steel conveying device, both the first bearing and the second bearing are 6208 deep groove ball bearings.
[0016] Based on the above configuration, the high-quality 6208 bearings used in the device possess excellent rolling performance, reducing friction, lowering energy consumption, and improving equipment operating efficiency. This characteristic enables the device to remain stable during long-term operation, extending its service life and reducing maintenance frequency.
[0017] In the preferred embodiment of the above-mentioned steel conveying device, the bottom of the positioning shaft passes through the worktable and is fixedly installed by a nut, and the bottom of the positioning shaft has a threaded structure that mates with the nut.

[0019] In the preferred embodiment of the above-mentioned steel conveying device, a top cover is installed on the top of the conveying roller to enclose the internal structure of the conveying roller.
[0020] Based on the above design, the pressure cap not only prevents dust but also prevents the intrusion of external impurities, reducing damage to the internal structure and thus enhancing the equipment's durability. A clean operating environment helps improve production efficiency and ensure product quality.
[0021] In the preferred embodiment of the above-mentioned steel conveying device, the retaining ring is a ∮40 retaining ring.
[0022] Based on the above settings, a ∮40 retaining ring is adopted. Its size is reasonable and its installation is convenient. Through precise limiting, it further improves the stability of the bearing and related components, reduces the risk of vibration and loosening, and ensures the continuity and efficiency of the conveying device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] First refer to Figure 1 ,like Figure 1 As shown, this utility model provides a steel conveying device for conveying steel between rolling mills. The conveying device includes a worktable 6, the top surface of which forms a support surface for supporting the steel being conveyed. It should be noted that this utility model does not impose any restrictions on the specific structure of the worktable 6. Those skilled in the art can set it according to their needs. For example, the worktable 6 can be a square worktable 6, or for example, the worktable 6 can be a circular worktable 6, as long as the worktable 6 is large enough to accommodate the working equipment.
[0031] Two rows of roller shaft assemblies are provided on the support surface, with each roller shaft assembly arranged along a first direction. Each roller shaft assembly includes a positioning shaft 3, a conveying roller 4, a bearing assembly, and a fixing assembly. The conveying roller 4 is sleeved on the outside of the positioning shaft 3 via the bearing, and the fixing assembly is used to position the bearing assembly and the positioning shaft 3. The centerline of the positioning shaft 3 is perpendicular to the support surface. The roller surface of the conveying roller 4 in the two rows of roller shaft assemblies cooperates with the support surface to form a steel conveying groove for defining the steel conveying direction. The circumferential surface of each conveying roller 4 is used for rolling friction cooperation with the side of the conveyed steel. Of course, it should be noted that this utility model does not impose any restrictions on the specific structure of the conveying roller 4. Those skilled in the art can set it according to their needs. For example, the conveying roller 4 can be a roller body with an anti-collision structure, or it can be a roller body made of rubber material, as long as it is ensured that the contact between the roller body and the steel will not damage the steel.
[0032] The steel anti-scratch device in this application significantly reduces surface scratches on steel during transportation by replacing sliding friction with rolling friction. This design effectively reduces damage to steel caused by friction during the rolling process, improves the surface quality of the final product, and reduces the scrap rate due to surface defects.

For example, the first bearing 2 and the second bearing 8 can be ball bearings, or they can be roller bearings, as long as the first bearing 2 and the second bearing 8 can enable the conveying roller 4 to rotate around the positioning shaft 3. In this preferred embodiment, in the preferred technical solution of the above-mentioned steel conveying device, both the first bearing 2 and the second bearing 8 are 6208 deep groove ball bearings. The high-quality 6208 bearings used in the device have good rolling performance, reducing friction, lowering energy consumption, and improving the operating efficiency of the equipment. This characteristic allows the device to remain stable during long-term operation, extending its service life and reducing maintenance frequency. The inner side of the conveyor roller 4 has a first groove and a second groove, which facilitates the installation and positioning of the bearings. The engagement of the first bearing 2 with the first groove and the second bearing 8 with the second groove makes the bearings more stable during conveying, preventing a decrease in conveying accuracy due to shaking.

Or, the convex ring 10 can be tightened and fixed to the positioning shaft 3 by threads, as long as the convex ring 10 can form a limiting effect on the positioning shaft 3. The formation of the convex ring 10 on the positioning shaft 3, and the limiting support of the positioning shaft 3 by the contact between the bottom of the convex ring 10 and the worktable 6, while the convex ring 10 being located below the second bearing 8 to provide additional support for the bottom of the second bearing 8, further improves the stability and load-bearing capacity of the conveying device, and avoids bearing damage or displacement due to excessive load.
[0035] Furthermore, the fixing component includes a washer and a retaining ring 9. The washer is installed between the retaining ring and the second bearing 8 to protect the second bearing 8.

[0036] Furthermore, it should be noted that this utility model does not impose any restrictions on the specific installation structure of the retaining ring 9. Those skilled in the art can set it according to their needs.
