Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air-cooled lines in high-speed wire rod factories, and in particular relates to a novel air-cooled closely spaced transmission roller device. Background Art
[0002] For high-speed wire rod mills that produce high-quality air-cooled steel grades, the uneven cooling of wire rods on the air-cooling line has always been a problem that needs to be solved urgently. In particular, the temperature difference between the overlap point and the non-overlap point of the wire rod is large, which leads to an increase in the strength difference of the wire rod in the same circle and an increase in the fluctuation of the microstructure and performance. The main reasons are: (1) The gap between the dense rollers of the air-cooling line is too narrow, resulting in uneven air volume distribution of the fan; (2) The cooling rate at the overlap point is lower than that at the non-overlap point of the wire rod.
[0003] The utility model designs a novel air-cooled close-packed transmission roller device based on actual on-site conditions, which can solve the problem that the air volume of air-cooled steel wire rods is small at the dense roller table and cannot be fully cooled. Utility Model Content
[0004] The utility model provides a novel air-cooled closely spaced transmission roller device. By installing the novel air-cooled closely spaced transmission roller, the problem of uneven cooling of air-cooled steel wire rods can be solved, thereby obtaining better organizational performance.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel air-cooled close-packed transmission roller device, comprising close-packed transmission rollers and a heat dissipation device, wherein the close-packed transmission rollers comprise a roller body and a roller shaft, wherein both ends of the roller body are connected to the roller shaft, wherein the heat dissipation device is arranged on the roller shaft, and grooves are provided on both sides of the roller body in a symmetrical distribution, wherein the heat dissipation device is composed of a plurality of slotted heat sinks.
[0006] Preferably, the depth of the groove is no more than 15 mm.
[0007] Preferably, the edges of the groove are rounded, and the chamfer angle is 10°-15°.
[0008] Preferably, the end of the roller shaft is connected to a sprocket.
[0009] Preferably, a bearing seat is connected between the sprocket of the roller shaft and the heat dissipation device, and the bearing seat and the sprocket are connected via a spacer sleeve.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] By designing the grooves on the roller body, symmetrical circular grooves are set up so that the overlap points of the wire rods are suspended on both sides of the roller body of the close-packed drive rollers, and more air volume can be allocated for cooling. The arrangement method can be based on the different types of steel produced on site and the process requirements. All close-packed drive rollers with grooves or close-packed drive rollers with and without grooves are arranged alternately. This helps to accelerate cooling and reduce the frequency of steel head piercing and equipment failure. By designing a sprocket at the end of the roller shaft, multiple close-packed drive rollers on a roller table are driven by a reduction motor. The transmission speed of the close-packed rollers can be adjusted in real time, reducing the cooling speed difference of the wire rod at various locations, ensuring the stability of the produced wire rod structure performance; the bottom and upper edges of the circular grooves on both sides are chamfered, and are regularly polished to keep them smooth to avoid scratches caused by the front end of the wire rod during the falling process; the close-packed drive rollers are designed with heat sinks on both sides, which can effectively alleviate the heat dissipation of the close-packed drive rollers after contact with the wire rods and extend their service life.

The close-packed transmission roller 1 includes a roller body 11 and a roller shaft 12. The two ends of the roller body 11 are connected to the roller shaft 12. The heat sink 1 is arranged on the roller shaft 12. Grooves 13 are opened on both sides of the roller body 11 and are symmetrically distributed. The heat sink 4 is composed of a plurality of slotted heat sinks. Figure 2In the figure, A represents the overlap point of the wire rod, and B represents the non-overlap point of the wire rod. In this embodiment, grooves 13 are designed at the positions where the two ends of the roller body 11 of the closely spaced drive roller 1 contact the overlap point of the wire rod, so that the overlap point is in a suspended state, and the gap between the two closely spaced drive rollers 1 is increased. When the fan is started, the cooling air is blown in from bottom to top along the wind duct at an angle of 45°. At this time, the angle of the fan is adjusted so that more air volume can be distributed at the overlap points on both sides of the roller, thereby accelerating the cooling speed of the wire rod at the overlap point. The roller body 11, roller shaft 12, and heat dissipation device 2 of this embodiment are all solid cylindrical structures, and the roller body 11 and the roller shaft 12 are made of the same material, both of which are ductile iron.

[0019] As a preferred implementation of this embodiment, the edges of the groove 13 are rounded to 10°-15°, and an arc transition is adopted to prevent the front end of the wire rod from being scratched during the falling process.
[0020] As a preferred implementation of this embodiment, the end of the roller shaft 12 is connected to the sprocket 3, and the sprockets 3 are connected between adjacent closely spaced driving rollers 1 via chains. The multiple closely spaced driving rollers 1 can be driven by a reduction motor.
[0021] As a preferred implementation of this embodiment, a bearing seat 4 is connected between the sprocket 3 of the roller shaft 12 and the heat sink 2, and the bearing seat 4 and the sprocket 3 are connected via a spacer 5. The spacer 5 can prevent the bearing seat 4 and the sprocket 3 from relative displacement.
