Description

Technical Field

[0001] This utility model belongs to the field of steel rolling production and processing technology, and specifically relates to a cooling device for a high-speed wire rod finishing mill. Background Technology

[0002] The high-speed wire rod finishing mill is a key piece of equipment in a high-speed wire rod production line. It is an instrument used in the field of power and electrical engineering. Among them, the guide device is an indispensable and important component of the finishing mill equipment. It is generally installed on the mill stand, located before and after the roll pass. In the wire rod manufacturing process, the guide device is mainly used to guide and support the rolled workpiece to enter and exit the roll pass accurately and stably in a predetermined direction and state, reduce rolling failures, and ensure the safety of personnel and equipment. As one of the key pieces of equipment in wire rod rolling, the rationality of the structural design and installation of the guide device directly affects the quality of the rolled product and the production capacity of the mill. Currently, in the process of guiding high-temperature wire rod, due to the high temperature of the wire rod, the high temperature causes the guide block of the guide device to deform severely. On the one hand, the severely deformed guide block will affect the production guidance of the wire rod; on the other hand, the guide block is easily damaged due to the high temperature environment and needs to be replaced frequently. Replacement will affect the wire rod production line and seriously affect the production efficiency. Therefore, it is an objective need to develop a cooling device for high-speed wire rod finishing mills that has a reasonable structure, good cooling effect, and is easy to install and disassemble. Summary of the Invention

[0003] The purpose of this utility model is to provide a cooling device for a high-speed wire rod finishing mill that has a reasonable structure, good cooling effect, and is easy to install and disassemble.

[0004] The purpose of this utility model is achieved as follows: it includes a guide seat, a guide wheel assembly, and a guide block assembly. The guide block assembly includes a guide housing and a transition cover installed at the end of the guide housing. The outer dimensions of the transition cover gradually decrease from the cover opening end to the guide housing end. Cooling housings are installed at intervals on the outer sides of the guide housing and the transition cover. The cooling housing is connected and fixed to the guide housing by a first sealing assembly, and the cooling housing is connected and fixed to the transition cover by a second sealing assembly. Circulating water cooling pipes are arranged around the outer walls of the guide housing and the transition cover located inside the cooling housing. A water inlet pipe and an air outlet pipe are respectively provided at the top of the cooling housing, and a water outlet pipe and an air inlet pipe are respectively provided at the bottom of the cooling housing. The inlet of the circulating water cooling pipe is connected to the water inlet pipe, and the outlet of the circulating water cooling pipe is connected to the water outlet pipe. One end of the cooling housing is inserted into the guide seat and then connected and fixed by multiple sets of limiting assemblies.

[0005] The advantages of this device are as follows: Firstly, a cooling shell is installed on the outside of the guide shell and transition cover. Both ends of the cooling shell are sealed with sealing components, preventing cold air leakage. Cold air is then supplied to the cooling shell through the inlet pipe, cooling the outer walls of the guide shell and transition cover to prevent deformation due to excessive temperature, ensuring normal wire conduction. The cooled air, having absorbed heat, is discharged through the outlet pipe. Secondly, a circulating water cooling pipe is installed on the outside of the guide shell and transition cover. Cooling water is supplied to the circulating water cooling pipe through the inlet pipe, allowing the cooling water to further... The cooling system absorbs heat from the guide shell and transition cover, further cooling them to prevent deformation and damage caused by high temperatures. This reduces the frequency of replacement and effectively improves the production efficiency of the finishing mill. The cooled water, after absorbing heat, is discharged through the outlet pipe. Secondly, the limiting components allow for quick disassembly and installation of the cooling shell, making replacement convenient and fast. This device combines water cooling and air cooling, significantly improving the cooling effect of the guide shell and transition cover, increasing production efficiency, and facilitating easy and quick replacement of the cooling shell, making it easy to promote and use.

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings, but this description is not intended to limit the present invention in any way. Any changes or improvements made based on the teachings of the present invention shall fall within the protection scope of the present invention.

[0011] like Figures 1-3 As shown, this utility model includes a guide seat 1, a guide wheel assembly 2, and a guide block assembly 3. The guide block assembly 3 includes a guide housing 31 and a transition cover 32 installed at the end of the guide housing 31. The outer dimensions of the transition cover 32 gradually decrease from the cover opening end to the guide housing 31 end. Cooling housings 4 are installed at intervals on the outer sides of the guide housing 31 and the transition cover 32. The cooling housings 4 are connected and fixed to the guide housing 31 by a first sealing assembly, and the cooling housings 4 are connected and fixed to the transition cover 32 by a second sealing assembly. The first and second sealing assemblies are... To seal both ends of the cooling housing 4, a circulating water cooling pipe 5 is arranged around the outer wall of the guide housing 31 and the transition cover 32 located inside the cooling housing 4. The top of the cooling housing 4 is provided with a water inlet pipe 6 and an air outlet pipe 14, and the bottom of the cooling housing 4 is provided with a water outlet pipe 7 and an air inlet pipe 13. The inlet of the circulating water cooling pipe 5 is connected to the water inlet pipe 6, and the outlet of the circulating water cooling pipe 5 is connected to the water outlet pipe 7. One end of the cooling housing 4 is inserted into the guide seat 1 and then connected and fixed by multiple sets of limiting components 8. The limiting components make it easier and faster to disassemble or replace the cooling housing 4.

[0012] During the use of this device, the cooling housing 4, along with the guide housing 31 and the transition cover 32, is inserted into the guide seat 1. The limiting component 8 then secures the cooling housing 4 to the guide seat 1. The wire to be precision rolled is then guided into the guide housing 31 through the transition cover 32. Cold air is then supplied to the cooling housing 4 through the air inlet pipe 13. The first and second sealing components seal the cooling housing 4, preventing leakage of cold air. Once inside the cooling housing 4, the cold air cools the outer walls of the guide housing 31 and the transition cover 32, preventing deformation due to excessive temperature and ensuring normal wire transport. The cooled air, having absorbed heat, is discharged through the air outlet pipe 14. During the cooling process, cooling water is supplied to the circulating water cooling pipe 5 through the water inlet pipe 6. The cooling water flowing in the circulating water cooling pipe 5 further absorbs heat from the guide housing 31. The heat from the guide shell 31 and transition cover 32 is used to further cool the guide shell 31 and transition cover 32, which can prevent the guide shell 31 and transition cover 32 from deforming and being damaged due to the high temperature environment. This can reduce the frequency of replacement of the guide shell 31 and transition cover 32 and effectively improve the production efficiency of the finishing mill. The cooling water after absorbing heat is discharged from the outlet pipe 7. This device adopts a combination of water cooling and air cooling, which can significantly improve the cooling effect of the guide shell and transition cover and improve production efficiency.

[0013] Furthermore, to improve the cooling effect of the guide shell and the transition cover, an upper baffle 9 is installed inside the cooling shell 4 above the guide shell 31. Multiple upper heat dissipation fins 10 are evenly spaced on the top of the guide shell 31 and the transition cover 32, extending above the upper baffle 9. A lower baffle 11 is installed inside the cooling shell 4 below the guide shell 31. Multiple lower heat dissipation fins 12 are evenly spaced on the bottom of the guide shell 31 and the transition cover 32, extending below the lower baffle 11. Multiple connecting holes are provided on the upper baffle 9 and the lower baffle 11. The air outlet pipe 14 is located above the upper baffle 9, and the air inlet pipe 13 is located below the lower baffle 11. Cold air enters from the bottom of the cooling shell 4, passes through the lower baffle 11, and then flows upward through the connecting holes to the guide shell 31 and the transition cover. The air 32 comes into contact with the guide shell 31 and the transition cover 2, absorbing heat during the contact process. The cooled air, after absorbing heat, continues to flow upward and enters the space above the upper partition 9 through the connecting holes of the upper partition 9. Finally, it is discharged through the exhaust pipe 14. During this process, the upper heat dissipation fins 10 can transfer the heat of the guide shell 31 and the transition cover 32 upward, and the lower heat dissipation fins 12 can transfer the heat of the guide shell 31 and the transition cover 32 downward, allowing them to fully contact the cooled air and achieve a better cooling effect. Preferably, a stirrer 15 is installed in the cooling shell 4 below the lower partition 11. The stirrer 15 can disperse the cooled air entering the cooling shell 4, allowing it to be evenly distributed around the guide shell 31 and the transition cover 32 through the connecting holes on the lower partition 11, further improving the cooling effect.

[0014] To improve the sealing performance at both ends of the cooling housing 4, the structure of the first sealing assembly is the same as that of the second sealing assembly. The first sealing assembly includes an end cap 16, a dynamic sealing ring 17, and a sealing gasket 18. A baffle 19 matching the guide housing 31 is fixedly installed on the inner wall of the cooling housing 4. The dynamic sealing ring 17 is installed on the guide housing 31 outside the baffle 19, and a sealing groove is machined on the dynamic sealing ring 17. The sealing gasket 18 is installed on the outside of the dynamic sealing ring, and a first sealing lip and a second sealing lip are provided on the sealing gasket 18. The first sealing lip is installed in the sealing groove, and the second sealing lip is installed between the dynamic sealing ring 17 and the cooling housing 4. The end cap 16 is installed on the guide housing 31 outside the sealing gasket 18. The end cap 16, the sealing gasket 18, and the cooling housing 4 are connected. The cooling housing 4 is connected and fixed by multiple fastening screws 20. During installation, the cooling housing 4 is installed on the outside of the guide housing 31 and the transition cover 32, so that the baffle 19 on the inside of the cooling housing 4 contacts the outer wall of the guide housing 31 and the transition cover 32. Then, the dynamic sealing ring 17 is installed on the outside of the guide housing 31 and the transition cover 32 and contacts the corresponding baffle 19. Then, the sealing gasket 18 and the end cap 16 are installed in sequence on the outside of the dynamic sealing ring 17. Finally, the end cap 16, the sealing gasket 18 and the cooling housing 4 are connected and fixed by fastening screws 20. The first sealing component and the second sealing component used in this device are interlocked between the dynamic sealing ring 17 and the sealing gasket 18. The sealing lip provided on the sealing gasket 18 is in close contact with the dynamic sealing ring 17 to achieve a good sealing effect and is relatively easy to disassemble and replace.

[0015] Furthermore, the limiting component 8 includes a pull block 81 and a pull rod 82. A limiting cavity 83, which is smaller at both ends and larger in the middle, is machined through the guide seat 1. A limiting groove matching the limiting cavity 83 is machined on the side wall of the guide housing 31. A limiting plate 84 is installed in the limiting cavity 83 near the limiting groove. A limiting post 85 is installed on the limiting plate 84 near the limiting groove. The end of the limiting post 85 is inserted into the limiting groove. The pull rod 82 is installed away from the limiting groove. On one side of the limiting plate 84, a movable plate 87 is slidably mounted on the pull rod 82 located within the limiting cavity 83. A telescopic spring 88 is installed on the outside of the pull rod 82 between the limiting plate 84 and the movable plate 87. The end of the pull rod 82 extends to the outside of the guide seat 1. A pull block 81 is installed on the end of the pull rod 82 outside the guide seat 1. When it is necessary to replace the guide housing 31 and the transition cover 32, the pull block 81 is pulled, which moves the pull rod 82. When the telescopic spring 88 is compressed, the movable plate 87 and the limiting plate 84 move with the pull rod 81, thereby causing the limiting post 85 connected to the limiting plate 84 to disengage from the limiting groove. This allows the cooling housing 4 to be easily removed from the guide seat 1. Then, the first sealing assembly and the second sealing assembly are disassembled, the guide housing 31 and the transition cover 32 are removed, and new guide housing 31 and the transition cover 32 are installed. The first sealing assembly and the second sealing assembly are then installed, and the pull block 81 is pulled back. Returning to the limiting cavity 83, the cooling housing 4 is inserted into the guide seat 1. The pull block 81 is released, the telescopic spring 88 extends, and the limiting post 82 abuts against the limiting groove again, thus realizing the installation of the cooling housing 4. Preferably, a rubber ring 86 is fixedly connected to the outer side of the limiting plate 84. The outer side of the rubber ring 86 is movably connected to the inner wall of the limiting cavity 83. The rubber ring 86 can reduce the friction between the limiting plate 84 and the inner wall of the limiting cavity 83, and extend the service life of the limiting cavity 83.
