Description

Technical Field

[0001] This invention relates to the field of composite wire thermal straightening machines, and more specifically, to a method for cooling the bearings of a composite wire thermal straightening machine. Background Technology

[0002] Currently, when composite hot wire undergoes hot rolling and then hot straightening, the bearings inside the straightening machine are particularly prone to damage. This is mainly due to the rolling process during hot straightening, where the temperature of the produced wire is generally between 300-500 degrees Celsius, typically around 500 degrees Celsius. At this point, the heat from 500 degrees Celsius radiates onto the body of the straightening machine. A typical hot straightening machine is designed with frames on both sides and rollers in the middle, using an upper and lower roller configuration. There are five-roll or seven-roll hot straightening machines. The problem with this design is that the rollers are relatively short, and the internal space is small. When wire passes through, the limited space and the wire's temperature (typically above 500 degrees Celsius) cause a significant amount of heat to be conducted to the frames on both sides. These frames then transfer this heat to the bearings, causing the lubricating oil inside to melt and evaporate quickly. This results in dry friction in the bearings. Furthermore, most bearings cannot withstand such high temperatures (300-500 degrees Celsius), making them particularly prone to damage. Summary of the Invention

[0003] 1. Technical problems to be solved

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a method for cooling the bearings of a composite wire thermal straightening machine. This method can absorb and dissipate heat from the machine frame by creating a cavity inside the frame and using water cooling or air cooling. It can also reduce the heat impact from thermal radiation. When the heat on the frame is too high, an emergency cooling and early warning effect can be achieved through an emergency panel.

[0005] 2. Technical Solution

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A method for cooling the bearings of a composite wire thermal straightening machine includes the following steps:

[0008] S1. Install multiple upper bearing housings and bearing sleeves simultaneously between two frames;

[0009] S2. Pass the linear workpiece between the upper bearing housing and the bearing cylinder, and connect it to the external traction equipment;

[0010] S3. Install multiple emergency panels on the outside of the two racks respectively, and connect them to the cavities inside the racks;

[0011] S4. Water cooling is adopted. First, connect the inlet pipe to the inlet and the outlet pipe to the outlet. Then, the water circulation is formed by connecting an external water pump and the external water pump is started.

[0012] Furthermore, the emergency tray includes a storage block, and a storage hopper is formed inside the storage block. The storage hopper is filled with potassium nitrate powder. A threaded pipe is connected to the top of the storage hopper, and a connecting block is screwed onto the outer surface of the threaded pipe. Multiple sets of through holes are formed on the arc-shaped contour of the storage block, and an insulating membrane is fitted onto the arc-shaped contour of the storage block. Due to the material properties of the insulating membrane, when the cooling water absorbs heat and the water temperature rises to a certain temperature, the insulating membrane will melt. At this time, after the insulating membrane melts, the cooling water in the cavity will enter the storage hopper through the through holes and mix with the potassium nitrate powder filled inside. When the potassium nitrate powder comes into contact with the water, an endothermic reaction will occur, thereby reducing the temperature of the water body, enhancing the cooling effect of water cooling, and avoiding damage to the bearings caused by continuous high temperature.

[0013] Furthermore, a sealing ring is provided between the storage block and the connecting block. The sealing ring is fitted onto the threaded pipe. By setting the sealing ring, the sealing effect at the connection block and the threaded pipe can be improved, reducing the risk of water leakage.

[0014] Furthermore, a fixing cover is fixedly connected to the upper surface of the connecting block, and a threaded ring is connected through the outer side of the frame. The fixing cover and the threaded ring are screwed together. By setting the fixing cover and the threaded ring together, the installation and disassembly of the emergency tray can be facilitated, and the replenishment of potassium nitrate powder in the storage bin can be facilitated. It also further improves the sealing effect at the connection block and the threaded pipe, and reduces the risk of water leakage.

[0015] Furthermore, a water-absorbing ring adapted to the fixed cover is fixedly connected to the lower surface of the fixed cover. The water-absorbing ring is made of highly absorbent resin. The water-absorbing ring is made of highly absorbent resin and is fixedly connected to the lower surface of the fixed cover. This allows the fixed cover to absorb water and expand when accidental water leakage occurs at the water-absorbing ring, thereby enhancing the sealing effect at the water-absorbing ring.

[0016] Furthermore, the material used for the storage block, threaded pipe, connecting block, and fixing cover is copper. Copper has excellent thermal conductivity, which greatly improves the heat dissipation of the frame when used as the material for the storage block, threaded pipe, connecting block, and fixing cover.

[0017] Furthermore, multiple heat dissipation protrusions are provided on the outer walls of the two racks, and the multiple heat dissipation protrusions are all made of copper. Multiple grooves are formed on the multiple heat dissipation protrusions, and the grooves are hemispherical in shape. By setting multiple copper heat dissipation protrusions on the outer walls of the racks, the heat dissipation area of ​​the racks can be increased, and the heat dissipation rate of the racks can be enhanced. By forming multiple grooves on the multiple heat dissipation protrusions, the surface area of ​​the outer walls of the heat dissipation protrusions can be increased, thereby increasing the heat dissipation area of ​​the heat dissipation protrusions and enhancing the cooling effect.

[0018] Furthermore, a transparent block is continuously connected to the upper surface of the connecting block, and the top of the transparent block is continuously connected to the fixed cover. A moisture test strip is adhered to one side of the transparent block inside the connecting block. The transparent block is continuously connected to both the connecting block and the transparent block, and is made of transparent material. When the barrier membrane melts at high temperature, and water enters the storage block and the connecting block through the through holes, the moisture test strip inside changes color upon contact with water, immediately changing from red to fluorescent. This allows inspectors to promptly detect excessively high temperatures on the frame and take preventative measures.

[0019] Furthermore, the outer walls of the upper bearing housing, bearing cylinder, and frame are all coated with heat-resistant radiation-resistant paint. By applying heat-resistant radiation-resistant paint to the outer walls of the upper bearing housing, bearing cylinder, and frame, the effect of blocking heat radiation can be achieved, reducing the evaporation of lubricating oil inside the bearing due to heat, and avoiding dry friction problems in the bearing.

[0020] Furthermore, in S4, the water cooling is replaced with air cooling, the external water pump is replaced with a blower, the water inlet pipe is connected to the air outlet of the blower, and the end of the water outlet pipe away from the frame is set upward. With the above settings, the blower can blow cooling air into the cavity from the water inlet and water inlet pipe, and blow it out from the water outlet and water outlet pipe, accelerating the heat in the frame to be discharged outward, thereby achieving a rapid cooling effect.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the advantages of this invention are:

[0023] (1) This solution can quickly and continuously dissipate heat from (1) by opening a cavity in the frame and using water cooling and air cooling, which greatly enhances the heat dissipation effect of (1). At the same time, by applying heat radiation protection coating to the upper bearing seat, bearing cylinder and outer wall of the frame, the heat radiation can be blocked, reducing the evaporation of lubricating oil in the bearing and avoiding dry friction of the bearing.

[0024] (2) This solution utilizes the material properties of the insulating membrane to achieve the effect that when the cooling water absorbs heat and the water temperature rises to a certain temperature, the insulating membrane will melt. At this time, after the insulating membrane melts, the cooling water in the cavity will enter the storage bin through the through hole and mix with the potassium nitrate powder filled inside. After the potassium nitrate powder comes into contact with the water, an endothermic reaction will occur, thereby reducing the temperature of the water body, enhancing the cooling effect of water cooling, and avoiding continuous high temperature damage to the bearing.

[0025] (3) This solution can facilitate the installation and disassembly of the emergency tray by setting the fixed cover and the threaded ring, and at the same time facilitate the replenishment of potassium nitrate powder in the storage bin. It also further improves the sealing effect of the connecting block and the threaded pipe, and reduces the risk of water leakage.

[0026] (4) This solution uses transparent blocks to connect the connecting block and the transparent block respectively. Since the transparent block is made of transparent material, when the isolation membrane melts at high temperature, water enters the storage block and the connecting block through the through hole. When the water comes into contact with water, the moisture test paper inside changes color from red to fluorescent. This makes it easy for inspectors to detect that the temperature on the frame is too high in time and to take preventive measures.

[0027] (5) This solution can improve the sealing effect between the connecting block and the threaded pipe by setting a sealing ring, and reduce the risk of water leakage. The water-absorbing ring is made of highly absorbent resin and is fixedly connected to the lower surface of the fixed cover. When water leakage occurs at the water-absorbing ring, the fixed cover can absorb the water and expand, thereby enhancing the sealing effect at the water-absorbing ring.

[0028] (6) This solution utilizes the excellent thermal conductivity of copper as the material for the storage block, threaded pipe, connecting block and fixing cover, which can greatly improve the heat dissipation effect of the frame. By setting multiple copper heat dissipation protrusions on the outer wall of the frame, the heat dissipation area of ​​the frame can be increased and the heat dissipation rate of the frame can be enhanced. By opening multiple grooves on multiple heat dissipation protrusions, the surface area of ​​the outer wall of the heat dissipation protrusions can be increased, thereby increasing the heat dissipation area of ​​the heat dissipation protrusions and enhancing the cooling effect.

[0040] Example 1:

[0041] Please see Figure 1-6 A method for cooling the bearings of a composite wire thermal straightening machine includes the following steps:

[0042] S1. Simultaneously install multiple upper bearing seats 2 and bearing cylinders 3 between two frames 1;

[0043] S2. Pass the linear workpiece 4 between the upper bearing seat 2 and the bearing cylinder 3, and connect it to the external traction device;

[0044] S3. Install multiple emergency panels 8 on the outside of the two racks 1 respectively, and connect them to the cavity 5 inside the rack 1.

[0045] S4. Water cooling is adopted. First, the water inlet pipe 9 is connected to the water inlet 6 and the water outlet pipe 10 is connected to the water outlet 7. Then, the water circulation is formed by the external water pump and the external water pump is started.

[0046] The emergency control panel 8 includes a storage block 11, and a storage hopper is opened inside the storage block 11. The storage hopper is filled with potassium nitrate powder. A threaded pipe 12 is connected through the top of the storage hopper. A connecting block 13 is screwed onto the outer surface of the threaded pipe 12. Multiple sets of through holes 14 are opened on the arc-shaped contour of the storage block 11. An insulating membrane 15 is fitted on the arc-shaped contour of the storage block 11. Due to the material properties of the insulating membrane 15, when the cooling water absorbs heat and the water temperature rises to a certain temperature, the insulating membrane 15 will melt. At this time, after the insulating membrane 15 melts, the cooling water in the cavity 5 will enter the storage hopper through the through holes 14 and mix with the potassium nitrate powder filled inside. When the potassium nitrate powder comes into contact with the water, an endothermic reaction will occur, thereby reducing the temperature of the water body, enhancing the cooling effect of water cooling, and avoiding damage to the bearing caused by continuous high temperature.

[0047] A sealing ring 16 is provided between the storage block 11 and the connecting block 13. The sealing ring 16 is fitted onto the threaded pipe 12. By setting the sealing ring 16, the sealing effect at the connection block 13 and the threaded pipe 12 can be improved, and the risk of water leakage can be reduced.

[0048] A fixing cover 17 is fixedly connected to the upper surface of the connecting block 13, and a threaded ring 19 is connected through the outer side of the frame 1. The fixing cover 17 and the threaded ring 19 are screwed together. The screw connection between the fixing cover 17 and the threaded ring 19 facilitates the installation and disassembly of the emergency tray 8, and also facilitates the replenishment of potassium nitrate powder in the storage bin. It also further improves the sealing effect between the connecting block 13 and the threaded pipe 12, reducing the risk of water leakage.

[0049] A water-absorbing ring 18 is fixedly connected to the lower surface of the fixed cover 17. The water-absorbing ring 18 is made of highly absorbent resin. The water-absorbing ring 18 is fixedly connected to the lower surface of the fixed cover 17 so that when water accidentally leaks at the water-absorbing ring 18, the fixed cover 17 can absorb the water and expand, thereby enhancing the sealing effect at the water-absorbing ring 18.

[0050] The material used for the storage block 11, threaded pipe 12, connecting block 13 and fixing cover 17 is copper. Copper has good thermal conductivity, so using it as the material for the storage block 11, threaded pipe 12, connecting block 13 and fixing cover 17 can greatly improve the heat dissipation effect of the outlet 7.

[0051] Multiple heat dissipation protrusions 20 are provided on the outer walls of the two racks 1. All heat dissipation protrusions 20 are made of copper. Multiple grooves are formed on each heat dissipation protrusion 20. The shape of the grooves is hemispherical. By setting multiple copper heat dissipation protrusions 20 on the outer walls of the racks 1, the heat dissipation area of ​​the racks 1 can be increased, and the heat dissipation rate of the racks 1 can be enhanced. By forming multiple grooves on the heat dissipation protrusions 20, the surface area of ​​the outer walls of the heat dissipation protrusions 20 can be increased, thereby increasing the heat dissipation area of ​​the heat dissipation protrusions 20 and enhancing the cooling effect.

[0052] A transparent block 21 is connected through the upper surface of the connecting block 13, and the top of the transparent block 21 is connected through the fixed cover 17. A moisture test paper is attached to one side of the transparent block 21 inside the connecting block 13. The transparent block 21 is connected through the connecting block 13 and the transparent block 21 respectively. Since it is made of transparent material, when the isolation membrane 15 melts at high temperature, and water enters the storage block 11 and the connecting block 13 through the through hole 14, the moisture test paper inside changes color when it comes into contact with water, changing from red to fluorescent immediately. This allows inspectors to promptly detect that the temperature on the frame 1 is too high and take preventive measures.

[0053] The outer walls of the upper bearing housing 2, bearing cylinder 3, and frame 1 are all coated with heat-resistant radiation coating. By applying heat-resistant radiation coating to the outer walls of the upper bearing housing 2, bearing cylinder 3, and frame 1, the effect of blocking heat radiation can be achieved, reducing the evaporation of lubricating oil inside the bearing due to heat, and avoiding dry friction problems in the bearing.

[0054] The water cooling system used in S4 is replaced with air cooling, the external water pump is replaced with a blower, the water inlet pipe 9 is connected to the air outlet of the blower, and the end of the water outlet pipe 10 away from the frame 1 is set upward. With the above settings, the blower can blow cooling air from the water inlet 6 and the water inlet pipe 9 into the cavity 5 and blow it out from the water outlet 7 and the water outlet pipe 10, thereby accelerating the dissipation of heat from the frame 1 to the outside and achieving a rapid cooling effect.

[0055] The moisture test strip model is ADS15SFJC.

[0056] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
