Description

Technical Field

[0001] This application relates to the technical field of wire production, and particularly relates to a roller table device. Background Art

[0002] During the wire production process, after the rolled billet is discharged from the wire laying head, it is evenly scattered on the roller table. Since the temperature of the wire is too high at this time (750 - 1150 °C), in order to obtain suitable crystals, it is necessary to forcibly cool the wire on the roller table.

[0003] As the roller table that directly bears the wire, the surface of the roller shaft is in direct contact with the hot wire. Considering the cooling requirement of the wire and the protection of the roller shaft, the concept of a cooling type roller table is proposed. Currently, most of the cooling type roller tables are water-cooled roller tables. The water-cooled roller table is provided with a roller cavity inside the roller shaft, a water channel is arranged in the roller cavity, and a rotary joint is used to separate the inlet water and the return water. Since the water-cooled roller table is filled with water inside, it has a large weight, which will increase the operating energy consumption of the roller table. Moreover, it is also necessary to perform inlet and return water treatment, which leads to a complex structure and process flow. In addition, there are also problems of liquid leakage and corrosion, which will shorten the service life of the roller shaft. There is also a small part of the cooling type roller tables that are air-cooled roller tables. The air-cooled roller table is provided with an air-cooling module below the roller shaft, and the air-cooling module blows air to the roller table and the wire on the roller table to cool the roller table and the wire on the roller table by air cooling. The cooling efficiency of this air-cooled roller table is relatively low and cannot meet the requirements of fast-paced production.

[0004] It can be seen that the existing cooling type roller tables each have their own drawbacks. Therefore, how to improve them is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] In an implementation manner of the roller table device, a plurality of the exhaust hole groups are arranged on the peripheral wall of the roller shaft, and the exhaust hole groups are sequentially arranged at intervals in the axial direction of the roller shaft. A plurality of the through holes are arranged on the peripheral wall of the first pipe section, and the through holes are sequentially arranged at intervals in the axial direction of the first pipe section.

[0007] An embodiment of the roller path device, each of the exhaust hole groups includes a plurality of exhaust holes, and the exhaust holes of the same exhaust hole group are sequentially arranged at intervals in the circumferential direction of the roller shaft. The exhaust holes are long strip-shaped holes extending in the circumferential direction of the roller shaft.

[0009] An embodiment of the roller path device, the air duct is sequentially provided with a third pipe section, a second pipe section and the first pipe section along the air inlet direction. The inner diameter of the second pipe section is smaller than the inner diameter of the third pipe section and also smaller than the inner diameter of the first pipe section. The two ends of the inner circumferential surface of the second pipe section are provided with inclined surfaces to smoothly transition with the inner circumferential surface of the first pipe section and the inner circumferential surface of the third pipe section through the inclined surfaces.

[0010] An embodiment of the roller path device, the first air cooling module includes heat dissipation fins, and the heat dissipation fins are arranged on the outer periphery of the pipe section of the air duct located outside the roller cavity.

[0011] An embodiment of the roller path device, the roller shaft includes a roller body and a first shaft head and a second shaft head respectively assembled at both ends of the roller body. An installation channel is provided inside the first shaft head. The roller path further includes a fixing sleeve and a bearing. The fixing sleeve is located inside the roller cavity and is assembled with the second shaft head. The bearing is installed in the fixing sleeve.

[0026] To enable those skilled in the art of the present technology to better understand the technical solution of this application, the following further detailed description of this application will be given in conjunction with the accompanying drawings and specific embodiments.

[0027] This application provides a roller table device.

[0028] As Figure 1 shown, the roller table device provided by this application at least includes a roller table 10 and a first air cooling module 20.

[0029] Among them, the roller table 10 plays a role in carrying. The components carried on the roller table 10 can be wire rods. Of course, it is not limited to wire rods. The roller table 10 includes roller shafts 101. Usually, multiple roller shafts 101 are arranged in parallel. The roller shafts 101 can rotate. At least one exhaust hole group is provided on the peripheral wall of the roller shaft 101, and each exhaust hole group includes at least one exhaust hole A.

[0030] Among them, the first air cooling module 20 at least includes an air duct 201. The air duct 201 is used to conduct cooling gas. The cooling gas can be low-temperature compressed air or low-temperature waste gas generated during the production process. Of course, it is not limited to this.

[0031] As Figure 2 shown, the air duct 201 includes a first pipe section 2011. At least one through hole B is provided on the upper side of the peripheral wall of the first pipe section 2011 (i.e., the side facing the components carried by the roller shaft 101).

[0032] As Figure 3 shown, a roller cavity is provided inside the roller shaft 101. The first pipe section 2011 of the air duct 201 is located inside the roller cavity and does not rotate with the roller shaft. Each through hole B and each exhaust hole group are arranged in one-to-one correspondence, and the corresponding through hole B and exhaust hole group are located on the same radial section of the roller shaft 101.

[0033] When the components carried on the roller table 10 have a cooling requirement, cooling gas is introduced into the air duct 201. The cooling gas flows into the first pipe section 2011 of the air duct 201 and then discharges from the through holes B on the peripheral wall of the first pipe section 2011. Since each through hole B on the peripheral wall of the first pipe section 2011 and each exhaust hole group on the peripheral wall of the roller shaft 101 are arranged in one-to-one correspondence, and the corresponding through hole B and exhaust hole group are located on the same radial section of the roller shaft 101, when the roller shaft 101 rotates to a certain angle, the corresponding through hole B and exhaust hole group can be directly opposite. At this time, the cooling gas discharged from the through hole B can directly blow to the components carried on the roller table 10 through the exhaust hole group. Since the direct blowing distance is short, it has a high cooling efficiency and can quickly cool the components carried on the roller table 10 to the target temperature.

[0034] The roller device provided by the present application has a higher cooling efficiency than the air-cooled roller described in the background art, and can meet the needs of fast-paced production. Moreover, compared with the water-cooled roller, the introduction of cooling gas will not increase the roller load, thereby not increasing the operating energy consumption of the roller, and no water inlet and return treatment is required, so the structure and process flow are simple, and there is no leakage and corrosion problem, so the service life of the roller will not be shortened.

[0035] In a specific embodiment, Figure 1 As shown, the roller device further includes a driving module 30. The driving module 30 is used to drive the roller shaft 101 to rotate. The driving module 30 includes a power element 301, and the power element 301 can be an electric motor.

[0036] In a specific embodiment, Figure 1 As shown, each roller shaft 101 is connected to a power element 301 via a coupling, and one power element 301 drives one roller shaft 101 individually.

[0037] In a specific embodiment, Figure 5 As shown, multiple rollers 101 form a group, and one group shares one power element 301, which can reduce the number of power elements 301 and reduce equipment costs. Specifically, one roller 101 in a group is connected to the power element 301 through a coupling and serves as the power roller 101, and the other rollers 101 are connected to the power roller 101 through a transmission structure 302. The transmission structure 302 can be a chain transmission structure or a belt transmission structure. Figure 5 The middle part is a chain transmission structure.

[0038] In a specific embodiment, Figure 3 As shown, the first air cooling module 20 further includes a heat sink 202, which is arranged on the outer periphery of the pipe section of the air channel 201 located outside the roller cavity. When the cooling gas flows in the pipe section of the air channel 201 located outside the roller cavity, the cooling gas can be dissipated to the surrounding environment through the heat sink 202, so that the temperature of the cooling gas is lower when entering the roller cavity, thereby improving the cooling effect.

[0039] In a specific embodiment, Figure 2 or Figure 3As shown, the air duct 201 further includes a third pipe section 2013 and a second pipe section 2012. The third pipe section 2013, the second pipe section 2012, and the above-mentioned first pipe section 2011 are arranged in sequence along the intake direction. That is to say, after the cooling gas enters from the intake port of the air duct 201, it first flows through the third pipe section 2013, then through the second pipe section 2012, and then through the first pipe section 2011. Among them, the inner diameter of the second pipe section 2012 is smaller than that of the third pipe section 2013 and also smaller than that of the first pipe section 2011. With such a design, the internal pressure inside the third pipe section 2013 can be higher than the internal pressure inside the second pipe section 2012, so that more cooling gas can flow from the third pipe section 2013 to the second pipe section 2012. At the same time, the cooling gas can also be ejected from the first pipe section 2011 at a faster speed. Therefore, the cooling effect can be improved.

[0040] In a specific embodiment, as Figure 2 shown, inclined surfaces are provided at both ends of the inner peripheral surface of the second pipe section 2012 to smoothly transition with the inner peripheral surface of the first pipe section 2011 and the inner peripheral surface of the third pipe section 2013 through the inclined surfaces. In this way, the flow resistance of the cooling gas can be reduced.

[0041] In a specific embodiment, as Figure 3 shown, the first air cooling module 20 includes a cooling nozzle 203. The cooling nozzle 203 is assembled in the through hole B, and the assembly method is not limited. For example, it can be assembled by welding, interference fit, or screw assembly, etc. The diameter of the spray hole of the cooling nozzle 203 is smaller than the diameter of the through hole B, and the outlet of the cooling nozzle 203 is closer to the peripheral wall of the roller shaft 101 than the through hole B. With such a design, the range of the cooling gas is farther, and the upper part of the component carried on the roller path 10 can also be sprayed by the cooling gas, so it is more conducive to improving the cooling uniformity and cooling effect.

[0042] In a specific embodiment, the cooling nozzle 203 adopts a fan-shaped nozzle, and the width of the exhaust hole A along the axial direction of the roller shaft 101 is greater than the maximum spray surface width of the fan-shaped nozzle. With such a design, the spraying range of the cooling gas is wider, and both sides of the component carried on the roller path 10 can also be sprayed by the cooling gas, so it is more conducive to improving the cooling uniformity and cooling effect.

[0043] In a specific embodiment, a plurality of exhaust hole groups are provided on the peripheral wall of the roller shaft 101. In the figure, there are five exhaust hole groups provided on the peripheral wall of the roller shaft 101. Of course, it is not limited to five. Each exhaust hole group is arranged at intervals in the axial direction of the roller shaft 101. It can be arranged at equal intervals or at unequal intervals. A plurality of through holes B are provided on the peripheral wall of the first pipe section 2011. In the figure, there are five through holes B provided on the peripheral wall of the first pipe section 2011. Of course, it is not limited to five. Each through hole B is arranged at intervals in the axial direction of the first pipe section 2011. It can be arranged at equal intervals or at unequal intervals. With such a design, it is more conducive to improving the cooling efficiency.

[0044] In a specific embodiment, each exhaust hole group includes a plurality of exhaust holes A. In the figure, each exhaust hole group includes two exhaust holes A. Of course, it is not limited to two. The exhaust holes A in the same exhaust hole group are sequentially arranged at intervals in the circumferential direction of the roller shaft 101. The exhaust hole A is a long strip hole extending in the circumferential direction of the roller shaft 101, and the length of the exhaust hole A is less than half of the circumference of the roller shaft 101. With such a design, during the process of the roller shaft 101 rotating one week, the time when the exhaust hole A is aligned with the through hole B is longer, so it is more conducive to improving the cooling efficiency.

[0045] In a specific embodiment, as Figure 3 shown, the roller path 10 includes a first bearing sleeve group 102 and a second bearing sleeve group 103. The roller shaft 101 includes a roller body 1011 and a first shaft head 1012 and a second shaft head 1013 respectively assembled at both ends of the roller body 1011. The first bearing sleeve group 102 is sleeved on the outer periphery of the first shaft head 1012. The second bearing sleeve group 103 is sleeved on the outer periphery of the second shaft head 1013. The second shaft head 1013 is in transmission connection with the power element 301 or the transmission structure 302.

[0046] In a specific embodiment, limiting steps are provided at both ends of the roller body 1011 to limit the installation depth of the first shaft head 1012 and the second shaft head 1013 in the roller body 1011.

[0047] In a specific embodiment, as Figure 3 and Figure 4 shown, the roller path 10 includes a fixed sleeve 104 and a bearing 105. The fixed sleeve 104 is located inside the roller cavity and is assembled with the second shaft head 1013. The assembly method is not limited. For example, it can be welded assembly or threaded assembly, etc. The bearing 105 is assembled in the fixed sleeve 104. An installation channel is provided inside the first shaft head 1012, and the air duct 201 is inserted into the installation channel and the inner hole of the bearing 105. With such a design, the reliable installation of the air duct 201 is realized and the air duct 201 can be made not to rotate with the roller shaft 101.

[0048] In a specific embodiment, as Figure 4 shown, the roller path 10 includes a bearing limit plate 106. The bearing limit plate 106 is connected to one end of the fixed sleeve 104 away from the second shaft head 1013 through a threaded fastener 107, and can limit the axial position of the bearing 105 to ensure the reliable operation of the bearing 105.

[0049] In a specific embodiment, the roller table device includes a purging module. The purging module is located on the side of the roller table 10. During operation, the purging module blows air onto the components carried on the roller table 10, so as to purge the water vapor, some foreign objects, dust, etc. on the surfaces of the components carried on the roller table 10, thereby improving the cooling efficiency. The purging module includes a purging pipeline and a purging nozzle connected to the outlet of the purging pipeline. The center elevation of the purging module is preferably 50 mm above the roller table 10. The blowing direction of the purging nozzle is opposite to the traveling direction of the roller table 10 and forms an angle of 10° - 20° with the center line ( Figure 1 marked as L in it) extending along the arrangement direction of the roller shafts 101 of the roller table 10, so that the purging effect is good.

[0050] In a specific embodiment, the roller table device includes a second air-cooling module. The second air-cooling module is located below the roller table 10. During operation, the second air-cooling module blows air onto the roller table 10 and the components carried on the roller table 10. The second air-cooling module includes a fan. The second air-cooling module and the first air-cooling module 20 work together to further improve the cooling efficiency. In addition, since the first air-cooling module 20 blows cold air straight upward for a short distance, the probability that the sundries on the roller table 10 fall and damage the fan blades of the fan of the second air-cooling module can be reduced, thereby improving the service life of the fan of the second air-cooling module.

[0051] In a specific embodiment, the roller table device includes a receiving frame. The receiving frame is located below the roller table 10 and above the second air-cooling module. The receiving frame can further reduce the probability that the sundries on the roller table 10 fall and damage the fan blades of the fan of the second air-cooling module, thereby further improving the service life of the fan of the second air-cooling module.

[0052] The above specific embodiments can be combined with each other without conflict.

[0053] The above uses specific examples to elaborate on the principles and implementation manners of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
