Description
Technical Field
[0001] The utility model relates to the technical field of roll forming, in particular to a distortion correction seat group used for roll forming of automobile seat slide rails. Background Art
[0002] Taking into account the actual working conditions of automobile seats, at least the stiffness requirements of the automobile slide rail connection must be met so that in the event of emergency braking or an accident, the slide rail and the slide rail seat will not be deformed or separated due to the up and down forces, avoiding the driver (or passenger) from being thrown out together with the seat. Steel plates with thickness, strength and stiffness that meet the requirements must be used for processing.
[0003] In the existing technology, the forming of automobile seat slides is all done by traditional large punching machines, which can meet the needs of forming thicker plates. This forming process is complicated, slow, noisy, and has low output. It requires manual feeding. Low output requires more people to be involved in production, with high production costs, and a lot of stamping waste and a high number of defective stamping products, which also have a certain impact on the physical and mental health of the operators who work in this area for a long time. With the development of science and technology, seat slides are gradually rolled. During the rolling process, the force and friction exerted by the rolling block on the sheet will cause the rolling block to be subjected to reaction force and friction, thereby causing the surface temperature of the rolling block to increase. Under the influence of the physical properties of thermal expansion and contraction, the surface of the rolling block may be hot and cold, resulting in local deformation or damage, thereby affecting the rolling accuracy. Therefore, it is necessary to improve its cooling structure. To this end, the inventor proposes a distortion correction seat group for rolling forming of automobile seat slides to solve the above-mentioned technical problem of reducing the physical influence of thermal expansion and contraction on the rolling block during the rolling process by adding a cooling structure. Utility Model Content
[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution to the above-mentioned problems.
[0005] A twist correction seat assembly for roll-forming a slide rail of an automobile seat, comprising a frame, a support frame and a connecting frame, wherein two ends of the connecting frame are respectively in contact with the surface of the support frame, the support frame is installed at the middle of the frame, a correction component is connected to the surface of the connecting frame, the correction component comprises a rotating shaft and a correction pressure block, the rotating shaft is symmetrically installed on the surface of the connecting frame, the correction pressure block is located on the surface of the rotating shaft, and is coaxially arranged with the rotating shaft, and a gap is provided between two adjacent correction pressure blocks;
[0006] The rotating shaft drives the correction block to rotate through the supporting roller, the surface of the rotating shaft is provided with a connection groove for assisting the positioning of the correction block, the middle of the correction block is provided with a matching hole for matching with the connection groove, the middle of the rotating shaft is provided with a flow channel opening, the inner surface of the flow channel opening is provided with a branch flow channel, the surface of the rotating shaft is provided with a connection hole for matching with the branch flow channel, the branch flow channel and the connection hole are connected, and a cooling structure is provided inside the correction block;
[0007] The cooling structure includes a cooling channel and a connecting block for matching with the connecting hole. An air inlet groove is provided in the middle of the connecting block. The air inlet groove and the connecting block are coaxially arranged. The connecting hole and the connecting block are coaxially arranged.
[0008] Several support blocks for increasing the supporting force are installed inside the cooling channel. The support blocks are distributed in a ring inside the cooling channel, and both ends are respectively abutted against the inner surface of the cooling channel. An exhaust hole is opened in the middle of the support block, and the exhaust hole runs through the surface of both ends of the support block.
[0009] Furthermore, the curvature of the support block is consistent with the curvature of the cooling channel, the distance between two adjacent support blocks is equidistantly arranged, and the exhaust hole and the support block are coaxially arranged; since the curvature of the support block is consistent with the curvature of the cooling channel, when the cooling medium (such as liquid or gas) flows in the channel, it can be smoother, reducing flow resistance and energy loss, thereby more effectively taking away heat and improving cooling efficiency. The use of equidistantly arranged support blocks can ensure that uniform support force is provided on the entire structure. This uniform distribution can prevent local excessive force or stress concentration, and enhance the stability and durability of the overall structure;
[0010] The coaxial arrangement of the exhaust hole and the support block allows the gas to be discharged or circulated more directly and efficiently, reducing the heat generated by the friction of the correction block during the rolling process during the processing, thereby avoiding the physical effects of thermal expansion and contraction, which may affect the accuracy and size of the rolled product. When the heat generated by the friction between the correction block and the material cannot be discharged in time, it may cause the correction block to anneal and cause changes in hardness, or cause other adverse effects. The coaxial exhaust hole can ensure that the cooling medium (such as liquid or gas) flows smoothly in the cooling channel, and the cooling medium inside the cooling channel reduces the physical effects of thermal expansion and contraction of the correction block, maintaining the smoothness and high efficiency of the cooling channel. Components with consistent curvature and size can reduce manufacturing errors, improve production efficiency, and reduce production costs.
[0011] Furthermore, one end of the rotating shaft is a socket for connecting to an external liquid nitrogen storage tank, the socket passes through the surface of the connecting frame, and the inside of the socket is in the shape of an internal thread;
[0012] First, the socket is designed to penetrate the surface of the connecting frame. This structure allows the liquid nitrogen storage tank to be easily connected to the rotating shaft. This connection method is both stable and easy to operate, ensuring the stability and reliability of the liquid nitrogen supply. Secondly, the inside of the socket adopts an internal thread shape, which can be tightly matched with the corresponding external thread of the external liquid nitrogen storage tank to form a well-sealed connection to prevent liquid nitrogen from leaking during transmission, ensuring the effective use of liquid nitrogen and the safety of the working environment. At the same time, installation and disassembly become simple and quick, and the staff can easily tighten or loosen the connection, improving work efficiency.
[0013] In addition, the design of the internal thread can adapt to liquid nitrogen storage tanks of different specifications and models, making the equipment more universal and flexible. Since the socket and the rotating shaft are coaxially arranged, when the rotating shaft and the correction block rotate during the rolling process, the pipeline of the liquid nitrogen storage tank can rotate together with the socket and the rotating shaft, thereby avoiding the force generated by the rotation from separating the socket from the pipeline of the liquid nitrogen storage tank and causing liquid nitrogen gas leakage.
[0014] Furthermore, a plurality of reinforcing ribs for increasing the supporting force are installed inside the air inlet groove, and an air outlet groove is opened in the middle of the reinforcing rib, which is respectively connected with the inside of the air inlet groove and the cooling channel. In the specific scenario of the air inlet groove, the reinforcing rib significantly reduces the probability of deformation of the connecting block by providing additional support, which is crucial for maintaining the shape and size of the air inlet groove, ensuring that the airflow can pass smoothly and stably;
[0015] Secondly, the air outlet groove opened in the middle of the reinforcing rib not only realizes the internal connection with the air inlet groove and the cooling channel, but also optimizes the air flow path. This design enables the cooling air flow to pass through the air inlet groove and the air outlet groove more efficiently, and then flow into the cooling channel to achieve a more effective cooling effect. At the same time, the interior of the cooling channel is supported and reinforced by the support block to avoid the reaction force of the correction block during the rolling process due to the cooling channel opened inside the correction block, thereby causing the probability of local deformation or damage to the correction block. Through the mutual cooperation of the above-mentioned structures, the probability of overall deformation can be effectively reduced, and at the same time, the air flow path and cooling efficiency are optimized, thereby improving the stability and performance of the entire structure.
[0016] Furthermore, an adjustment device is installed on the surface of the frame, and the adjustment device includes an adjustment toothed disc, an adjustment rod and a push rod. The adjustment toothed disc is installed in the middle of the frame, and one end of the adjustment toothed disc abuts against the surface of the support frame. The support frame and the connecting frame are both located on the surface of the adjustment toothed disc;
[0017] This layout enhances the stability and robustness of the overall structure. Since the support frame and the connecting frame are in direct contact with the adjusting toothed disc, the connection between them is tighter, reducing the risk of structural damage caused by looseness or vibration. At the same time, the adjusting toothed disc, as a central component, can evenly distribute the load from the support frame and the connecting frame, thereby improving the load-bearing capacity of the overall structure.
[0018] Secondly, this design makes the adjustment process more convenient and accurate. The adjusting toothed disc can be rotated or moved by the adjusting rod. By applying pressure at one end of the push rod, the adjusting toothed disc is locked, which plays the role of locking the adjusting toothed disc, thereby achieving precise angle adjustment of the support frame and the connecting frame. Since the support frame and the connecting frame are both located on the surface of the adjusting toothed disc, their position changes can be directly observed during the adjustment process, making the adjustment more intuitive and accurate. In addition, sufficient space is reserved in the middle of the adjusting toothed disc to facilitate the passage of materials between two adjacent correction blocks, so that the correction blocks can roll the materials into shape.
[0019] In addition, this layout also helps to improve space utilization. Since the adjusting gear plate is located in the middle of the frame, the distribution of the support frame and the connecting frame is more reasonable, avoiding space waste due to improper structural layout.
[0020] Furthermore, one end of the adjusting rod and the pushing rod are respectively provided with a fine-tuning knob and a fixed knob, and the surface of the adjusting rod is provided with a fine-tuning thread used in pair with the adjusting toothed disc, and the adjusting toothed disc and the fine-tuning thread are in meshing motion; the meshing design can achieve high-precision adjustment, and since the fine-tuning thread and the adjusting toothed disc are in meshing motion, the contact area between them is large and the friction is strong, so it can be ensured that subtle and precise movement is achieved during the adjustment process. Secondly, the design of the meshing motion makes the adjustment process smoother and more reliable. During the adjustment process, the adjusting rod is pushed by the fine-tuning knob, and the rotation of the adjusting rod will drive the fine-tuning thread to mesh with the adjusting toothed disc, thereby achieving precise angle adjustment of the target component by the adjusting toothed disc. Since the meshing motion is stable and continuous, it can ensure the smooth progress of the adjustment process, avoiding equipment failure or precision reduction caused by improper adjustment.
[0021] In addition, the meshing movement between the fine-tuning thread and the adjusting gear disc is a mechanical transmission method. Compared with other transmission methods, such as friction transmission or hydraulic transmission, it has better wear resistance and stability, which can ensure that the equipment can maintain high adjustment accuracy and stability during long-term use. The fine-tuning knob and the fixed knob are respectively installed at one end of the adjusting rod and the push rod, making the operation more convenient and quick, and easy to maintain and replace parts, which can significantly improve the efficiency of the easy assembly of the equipment.
[0022] Furthermore, a limit knob for limiting the position of the fine-tuning thread is installed on the top of the frame; the limit knob can be turned or locked by a nut to fix the position of the fine-tuning thread, thereby ensuring that the fine-tuning thread will not accidentally move or loosen during use, thereby improving the stability of the entire structure; in addition, through precise adjustment of the fine-tuning thread and the fixing effect of the limit knob, precise control of the position or angle of the adjusting toothed disc can be achieved to meet the needs of high-precision work; the presence of the limit knob can prevent the structural angle of the adjusting toothed disc from changing due to misoperation or external interference, thereby improving safety of use and improving the angle accuracy of roll forming.
[0023] Furthermore, the bottom of the frame is a base plate, and the frame and the base plate are L-shaped; the L-shaped design forms a stable support structure between the frame and the base plate, which can effectively disperse and bear the weight or external force from the upper part of the frame, ensuring the stability and safety of the entire structure, and can provide reliable support whether in a static state or under dynamic load. In addition, the L-shaped design makes it easier to position and align the frame and the base plate during installation. The design also provides more fixing points for installation, making it convenient to use bolts, welding or other connection methods to firmly fix the frame to the base plate, ensuring the stability of the structure.
[0024] Compared with the prior art, the beneficial effects of the utility model are:
[0025] 1. A cooling structure is provided inside the correction block, so that the cooling medium (such as liquid or gas) can flow smoothly in the cooling structure. The cooling medium inside the cooling structure reduces the heat generated by the friction of the correction block during the rolling process during the processing, thereby avoiding the physical effects caused by thermal expansion and contraction, which may affect the accuracy and size of the rolled product, or cause changes in hardness due to annealing of the correction block, or other adverse effects;
[0026] 2. Support blocks are used to support and reinforce the inside of the cooling channel to avoid the reaction force of the correction block during the rolling process due to the cooling channel inside the correction block, which may cause local deformation or damage to the correction block. The mutual cooperation of the support blocks can effectively reduce the probability of overall deformation, optimize the airflow path and cooling efficiency, and thus improve the stability and performance of the entire structure.

DETAILED DESCRIPTION
[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0038] For this example, please refer to Figure 1-Figure 9 , a distortion correction seat group for roll-forming of automobile seat slide rails is specifically implemented, comprising a frame 1, a support frame 2 and a connecting frame 3, the two ends of the connecting frame 3 are respectively in contact with the surface of the support frame 2, the support frame 2 is installed in the middle of the frame 1, and the surface of the connecting frame 3 is connected with a correction component, the correction component comprises a rotating shaft 4 and a correction pressure block 5, the rotating shaft 4 is symmetrically installed on the surface of the connecting frame 3, the correction pressure block 5 is located on the surface of the rotating shaft 4, and is coaxially arranged with the rotating shaft 4, and there is a gap between two adjacent correction pressure blocks 5;
[0039] The rotating shaft 4 drives the correction pressure block 5 to rotate through the supporting roller 6. The surface of the rotating shaft 4 is provided with a connecting groove 7 for assisting the positioning of the correction pressure block 5. The middle of the correction pressure block 5 is provided with a matching hole 8 for matching with the connecting groove 7. The middle of the rotating shaft 4 is provided with a flow channel opening 9. The inner surface of the flow channel opening 9 is provided with a branch flow channel 10. The surface of the rotating shaft 4 is provided with a connecting hole 11 for matching with the branch flow channel 10. The branch flow channel 10 is connected with the connecting hole 11. The inside of the correction pressure block 5 is provided with a cooling structure.
[0040] The cooling structure includes a cooling channel 12 and a connecting block 13 for matching with the connecting hole 11. An air inlet groove 14 is provided in the middle of the connecting block 13. The air inlet groove 14 and the connecting block 13 are coaxially arranged. The connecting hole 11 and the connecting block 13 are coaxially arranged.
[0041] A plurality of support blocks 15 for increasing the supporting force are installed inside the cooling channel 12. The support blocks 15 are distributed in an annular manner inside the cooling channel 12, and both ends are respectively abutted against the inner surface of the cooling channel 12. An exhaust hole 16 is opened in the middle of the support block 15, and the exhaust hole 16 runs through the surface of both ends of the support block 15.
[0042] The curvature of the support block 15 is consistent with that of the cooling channel 12, the distance between two adjacent support blocks 15 is equidistantly arranged, and the exhaust hole 16 is coaxially arranged with the support block 15; since the curvature of the support block 15 is consistent with that of the cooling channel 12, when the cooling medium (such as liquid or gas) flows in the channel more smoothly, the flow resistance and energy loss are reduced, thereby more effectively taking away heat and improving the cooling efficiency. The use of equidistantly arranged support blocks 15 can ensure that uniform support force is provided on the entire structure. This uniform distribution can prevent local excessive force or stress concentration, and enhance the stability and durability of the overall structure;
[0043] The coaxial arrangement of the exhaust hole 16 and the support block 15 allows the gas to be discharged or circulated more directly and efficiently, reducing the heat generated by the friction of the correcting block 5 during the rolling process during the processing, thereby avoiding the physical effects of thermal expansion and contraction, which may affect the accuracy and size of the rolled product. When the heat generated by the friction between the correcting block 5 and the material cannot be discharged in time, it may cause the correcting block 5 to anneal and cause a change in hardness, or cause other adverse effects. The coaxially arranged exhaust hole 16 can ensure that the cooling medium (such as liquid or gas) flows smoothly in the cooling channel 12, and the cooling medium inside the cooling channel 12 reduces the physical effects of the thermal expansion and contraction of the correcting block 5, maintains the smoothness and high efficiency of the cooling channel 12, and the components and dimensions with consistent curvature can reduce manufacturing errors, improve production efficiency, and reduce production costs.
[0044] One end of the rotating shaft 4 is a socket 17 for connecting to an external liquid nitrogen storage tank. The socket 17 passes through the surface of the connecting frame 3. The inside of the socket 17 is in the shape of an internal thread. The flow channel 9 is connected to the socket 17. The liquid nitrogen enters the inside of the flow channel 9 through the socket 17.
[0045] First, the socket 17 is designed to penetrate the surface of the connecting frame 3. This structure enables the liquid nitrogen storage tank to be easily connected to the rotating shaft. This connection method is both stable and easy to operate, ensuring the stability and reliability of the liquid nitrogen supply; secondly, the inside of the socket 17 adopts an internal thread shape, and the internal thread can be tightly matched with the corresponding external thread of the external liquid nitrogen storage tank to form a well-sealed connection to prevent liquid nitrogen from leaking during the transmission process, ensuring the effective use of liquid nitrogen and the safety of the working environment. At the same time, installation and disassembly become simple and quick, and the staff can easily tighten or loosen the connection, thereby improving work efficiency;
[0046] In addition, the design of the internal thread can adapt to liquid nitrogen storage tanks of different specifications and models, making the equipment more universal and flexible. Since the socket 17 is coaxially arranged with the rotating shaft 4, when the rotating shaft 4 and the correction pressure block 5 rotate during the rolling process, the pipeline of the liquid nitrogen storage tank can rotate together with the socket 17 and the rotating shaft 4, thereby avoiding the force generated by the rotation from separating the socket 17 from the pipeline of the liquid nitrogen storage tank, causing liquid nitrogen gas leakage.
[0047] The air inlet groove 14 is provided with a plurality of reinforcing ribs 18 for increasing the supporting force. An air outlet groove 19 is provided in the middle of the reinforcing rib 18. The air outlet groove 19 is respectively connected with the air inlet groove 14 and the interior of the cooling channel 12. In the specific scenario of the air inlet groove 14, the reinforcing rib 18 significantly reduces the probability of deformation of the connecting block 13 by providing additional support, which is essential for maintaining the shape and size of the air inlet groove 14 and ensuring that the airflow can pass smoothly and stably.
[0048] Secondly, the air outlet groove 19 opened in the middle of the reinforcing rib 18 not only realizes the internal penetration with the air inlet groove 14 and the cooling channel 12, but also optimizes the air flow path. The adoption of this design enables the cooling air flow to pass through the air inlet groove 14 and the air outlet groove 19 more efficiently, and then flow into the cooling channel 12, thereby achieving a more effective cooling effect. At the same time, the interior of the cooling channel 12 is supported and reinforced by the support block 15 to avoid the reaction force of the correction block 5 during the rolling process caused by the cooling channel 12 opened inside the correction block 5, thereby causing the probability of local deformation or damage of the correction block 5. Through the mutual cooperation of the above-mentioned structures, the probability of overall deformation can be effectively reduced, and at the same time, the air flow path and cooling efficiency are optimized, thereby improving the stability and performance of the entire structure.
[0049] An adjusting device is installed on the surface of the frame 1, and the adjusting device includes an adjusting toothed disc 20, an adjusting rod 21 and a pushing rod 22. The adjusting toothed disc 20 is installed in the middle of the frame 1, and one end of the adjusting toothed disc 20 abuts against the surface of the supporting frame 2. The supporting frame 2 and the connecting frame 3 are both located on the surface of the adjusting toothed disc 20.
[0050] This layout enhances the stability and robustness of the overall structure. Since the support frame 2 and the connecting frame 3 are in direct contact with the adjusting toothed disc 20, the connection between them is tighter, reducing the risk of structural damage due to looseness or vibration. At the same time, the adjusting toothed disc 20, as a central component, can evenly distribute the load from the support frame 2 and the connecting frame 3, thereby improving the load-bearing capacity of the overall structure.
[0051] Secondly, the design makes the adjustment process more convenient and accurate. The adjustment toothed disc 20 can be rotated or moved by the adjustment rod 21. The adjustment toothed disc 20 is stuck by applying pressure at one end of the push rod 22, which plays a role in locking the adjustment toothed disc 20, thereby achieving precise angle adjustment of the support frame 2 and the connecting frame 3. Since the support frame 2 and the connecting frame 3 are both located on the surface of the adjustment toothed disc 20, their position changes can be directly observed during the adjustment process, making the adjustment more intuitive and accurate. In addition, sufficient space is reserved in the middle of the adjustment toothed disc 20 to facilitate the passage of materials between two adjacent correction pressing blocks 5, so that the correction pressing blocks 5 can roll-form the materials.
[0052] In addition, this layout also helps to improve the utilization of space. Since the adjusting gear plate 20 is located in the middle of the frame 1, the distribution of the support frame 2 and the connecting frame 3 is more reasonable, avoiding space waste due to improper structural layout.
[0053] The adjusting rod 21 and the pushing rod 22 are respectively provided with a fine-tuning knob 23 and a fixed knob 24 at one end. The surface of the adjusting rod 21 is provided with a fine-tuning thread 25 used in pair with the adjusting toothed disc 20. The adjusting toothed disc 20 and the fine-tuning thread 25 are in meshing motion. The meshing design can achieve high-precision adjustment. Since the fine-tuning thread 25 and the adjusting toothed disc 20 are in meshing motion, the contact area between them is large and the friction is strong, so it can be ensured that subtle and precise movement is achieved during the adjustment process. Secondly, the meshing motion design makes the adjustment process smoother and more reliable. During the adjustment process, the adjusting rod 21 is pushed by the fine-tuning knob 23. The rotation of the adjusting rod 21 will drive the fine-tuning thread 25 to mesh with the adjusting toothed disc 20, thereby achieving precise angle adjustment of the target component by the adjusting toothed disc 20. Since the meshing motion is stable and continuous, it can ensure the smooth progress of the adjustment process, avoiding equipment failure or precision reduction caused by improper adjustment.
[0054] In addition, the meshing movement between the fine-tuning thread 25 and the adjusting toothed disc 20 is a mechanical transmission method, which has better wear resistance and stability than other transmission methods, such as friction transmission or hydraulic transmission, and can ensure that the equipment can maintain high adjustment accuracy and stability during long-term use. The fine-tuning knob 23 and the fixed knob 24 are respectively installed at one end of the adjusting rod 21 and the pushing rod 22, making the operation more convenient and quick, and facilitating maintenance and replacement of parts, which can significantly improve the efficiency of easy assembly of the equipment.
[0055] A limit knob 26 for limiting the position of the fine-tuning thread 25 is installed on the top of the frame 1; the limit knob 26 can be turned or locked by a nut to fix the position of the fine-tuning thread 25, ensuring that the fine-tuning thread 25 will not accidentally move or loosen during use, thereby improving the stability of the entire structure. In addition, through the precise adjustment of the fine-tuning thread 25 and the fixing effect of the limit knob 26, precise control of the position or angle of the adjusting toothed disc 20 can be achieved to meet the needs of high-precision work. The presence of the limit knob 26 can prevent the structural angle of the adjusting toothed disc 20 from changing due to misoperation or external interference, thereby improving the safety of use and improving the angle accuracy of the rolling forming.
[0056] The bottom of the frame 1 is a base plate 27, and the frame 1 and the base plate 27 are L-shaped. The L-shaped design forms a stable support structure between the frame 1 and the base plate 27, which can effectively disperse and bear the weight or external force from the upper part of the frame 1, ensuring the stability and safety of the entire structure, and can provide reliable support whether in a static state or under dynamic load. In addition, the L-shaped design makes it easier to position and align the frame 1 and the base plate 27 during installation. The design also provides more fixing points for installation, making it convenient to use bolts, welding or other connection methods to firmly fix the frame to the base plate, ensuring the stability of the structure.
[0057] The key points of the design of the present invention are as follows: by providing a cooling structure inside the correction block 5, a cooling medium (such as liquid or gas) can be smoothly circulated in the cooling structure, and the cooling medium inside the cooling structure can reduce the heat generated by the friction of the correction block 5 during the rolling process during the processing, thereby avoiding the physical influence of thermal expansion and contraction, which may affect the accuracy and size of the rolled product, or cause the correction block 5 to anneal and cause a change in hardness, or cause other adverse effects.
[0058] The action process of the utility model is as follows: the correction pressure block 5 is installed on the surface of the rotating shaft 4, and the correction pressure block 5 is supported by the support roller 6 to reduce the force on the rotating shaft 4. When the correction pressure block 5 is connected to the rotating shaft 4, the connecting hole 11 is aligned with the connecting block 13, so that the connecting block 13 extends into the connecting hole 11 and the inside of the branch channel 10. When the socket 17 is connected to the pipeline of the liquid nitrogen storage tank, the cooling medium (such as liquid or gas) enters the inside of the cooling channel 12 through the channel opening 9, the branch channel 10, the connecting hole 11, the air inlet groove 14 and the air outlet groove 19. This design enables the cooling airflow to flow into the cooling channel 12 more efficiently, thereby achieving a more effective cooling effect.
[0059] When the cooling medium (such as liquid or gas) enters the cooling channel 12, the cooling medium gradually fills the interior of the cooling channel 12 through the support block 15 and the exhaust hole 16, so that the cooling effect is diffused or transferred from the inside to the outside of the correction block 5, thereby reducing the heat generated by the friction of the correction block 5 during the rolling process, thereby avoiding the physical effects of thermal expansion and contraction on the correction block 5, and reducing the effects of hardness changes of the correction block 5 caused by thermal annealing, further increasing the cooling efficiency while increasing the sustainability of the rolling process. When the process is completed or the specified time interval is reached, the liquid nitrogen storage tank pipeline connected to the surface of the socket 17 can be removed to allow the accumulated or residual gas to be discharged from the outside of the correction block 5 through the same path, thereby completing the cooling and rolling process.

[0061] The rotating shaft 4 drives the correction pressure block 5 to rotate through the supporting roller 6.
