Description

Technical Field

[0001] The utility model relates to the technical field of blooming mill components, and specifically relates to a novel conveying roller table. Background Art

[0002] When large-sized steel materials are rolled by a blooming mill, affected by rolling, the cross-section of the billet is large. When rolled by the blooming mill, the billet is rolled back and forth, and the phenomenon of both ends bending (the stock head generally bends downward) often occurs. Therefore, the impact on the front and rear conveying roller tables of the blooming mill is relatively large, resulting in deformation of the roller table, frequent welding detachment of the support roller barrel shaft end covers, and only the temporary welding method can be used to extend the service life. The main reason is that end covers and short shafts are welded at both ends of the roller barrel of the original roller table structure, and the middle is just the roller barrel. After the roller table is deformed under the impact of the middle billet elbow, the transmission shaft is not on the center line of the roller table, and the roller table fails frequently and needs to be replaced often. In the case of a relatively fast production rhythm, it affects production. Due to the large number of on-line roller tables, the operation risk of workers is high and the labor intensity is large.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0029] Please refer to Figures 1-7 , the present utility model provides a technical solution: as Figure 7 shown, a new type of conveying roller path includes: a roller 1 and end covers 5 provided at both ends of the roller 1; a long shaft 3, which is provided in a through groove opened in the roller 1, and the length of the long shaft 3 is greater than that of the roller 1, so that both ends of the long shaft 3 extend beyond the through groove to form end shafts, and the long shaft 3 and its end shafts are coaxial with the roller 1. The surface of the end cover 5 is provided with a first inner hole 10 for the end shaft to extend out, so as to fixedly connect the long shaft 3 and the roller 1 through the two end covers 5; one end of the end shaft of the long shaft 3 is connected to one end of a coupling, and the other end of the coupling is connected to the output end of a speed reducer;

[0030] Adopting the above technical solution can improve the strength of the conveying roller path. By opening a through groove inside the roller 1, it is beneficial to insert the long shaft 3 into the through groove and fix it with the roller 1, and then by welding the end covers 5 at both ends of the through groove and welding and fixing the end covers 5 with the long shaft 3, a high-strength conveying roller path is formed. The original short shaft fixed by the end covers 5 on both sides is changed to the long shaft 3 passing through the roller 1, increasing the impact resistance of the roller path, and overcoming the frequent problems of the roller path caused by the easy de-welding of the original roller path shaft and the deformation of the roller.

[0031] As Figure 1 and Figure 5As shown, in this embodiment, the end cap 5 is provided with welding grooves at its first inner hole 10 and outer edge, and the welding grooves are used for full welding connection with the long shaft 3 and the roller 1 respectively;

[0032] Adopting the above technical solution can conveniently fix the end cap 5 at the through groove of the roller 1, and at the same time fix the end cap 5 to the long shaft 3, so that the long shaft 3 can drive the end cap 5 to rotate, and then drive the roller 1 to rotate through the end cap 5.

[0033] As Figure 5 shown, in this embodiment, the surface of the end cap 5 is provided with first exhaust holes 7 for exhausting gas during welding; a triangular rib plate is additionally provided on the outer side of the end cap 5 for reinforcement;

[0034] Adopting the above technical solution can help exhaust the fumes during welding of the end cap 5 from the first exhaust holes 7.

[0035] As Figure 1 、 Figure 2 and Figure 4 shown, in this embodiment, the new conveying roller path further includes a strengthening structure, which is arranged between the through groove of the roller 1 and the long shaft 3 to improve the impact resistance of the long shaft 3 and the roller 1 in the radial direction; specifically, the strengthening structure includes: three rib plates 2 arranged at intervals along the length direction of the long shaft 3, the rib plates 2 are in conformity with the shape of the through groove of the roller 1, the rib plates 2 are of circular plate structure, the rib plates 2 are provided with second inner holes 9 for the long shaft 3 to pass through, and the rib plates 2 are respectively connected to the inner wall of the through groove of the roller 1 and the long shaft 3; the rib plates 2 are provided with welding grooves at their second inner holes 9, the welding grooves are used for full welding connection with the long shaft 3, the surfaces of the rib plates 2 are provided with second exhaust holes 8 for exhausting gas during welding, and the roller 1 is provided with long holes 6 corresponding to the rib plates 2 in its circumferential direction. During welding, the rib plates 2 and the roller 1 are connected together by surfacing welding in the long holes 6;

[0036] Adopting the above technical solution can help further improve the impact resistance of the conveying roller path. The design of the hollow interior of the roller 1 not only helps reduce the weight of the conveying roller path and save materials, but also can fill the gap between the through groove of the roller 1 and the long shaft 3 by setting the rib plates 2, taking into account the stiffness of the roller 1 and making its impact resistance better.

[0038] Adopting the above technical solution can further improve the impact resistance of the conveying roller path. The long strip-shaped connecting plate 4 can extend throughout the through groove of the roller 1. The connecting plate 4 cooperates with the rib plate 2 to fill the gap between the through groove of the roller 1 and the long shaft 3, improving the stiffness of the roller 1. The settings of the first notch 11, the second notch 12, and the third notch 13 are conducive to clamping and connecting the connecting plate 4 with the end cover 5 and the rib plate 2, facilitating positioning during welding.

[0039] Working principle: During use, first measure the dimensions, and weld the rib plates 2 and the two end covers 5 on the long shaft 3; snap the third notch 13 of the connecting plate 4 into the second notch 12 of the rib plate 2 and the first notch 11 of the end cover 5 respectively for welding, so that the connecting plate 4 connects all the rib plates 2 and the end covers 5; weld the connecting plate 4 and the long shaft 3 to form a long shaft assembly, and insert the long shaft assembly into the through groove of the roller 1 to assemble into a roller path; connect the rib plate 2 and the roller 1 together by surfacing welding in the long strip hole 6, and then grind the weld seam higher than the roller surface flat; perform full welding connection between the welding groove on the end cover 5 and the roller 1, and add triangular rib plates on the outside of the end cover 5 for reinforcement; after all the assembly and welding are completed, then machine the two end shafts of the long shaft 3 with the surface of the roller 1 as the reference, so that the coaxiality of the roller path meets the use requirements.

[0040] Thus, a series of work is completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
