Description

Technical Field

[0001] The invention relates to the technical field of metal plate rolling, and in particular to a metal plate rolling device for an electric cabinet and a rolling method thereof. Background Art

[0002] In the prior art, there are many problems that need to be solved in the field of electric cabinet metal plate rolling. Most traditional electric cabinet metal plate rolling devices rely on complex electronic control systems to adjust the roller speed to adapt to different rolling pressures. However, electronic control systems are not only expensive, but also easily affected by factors such as electromagnetic interference and temperature changes in actual operation, resulting in greatly reduced accuracy and response speed of speed regulation. During the rolling process, once the rolling pressure changes, the electronic control system may not be able to adjust the roller speed in a timely and accurate manner, resulting in a mismatch between the rolling speed and the pressure. This will not only reduce the rolling efficiency, but may also cause problems such as uneven thickness and poor surface quality of the metal plate, seriously affecting product quality. At the same time, long-term mismatched operation will also cause excessive wear on the equipment and shorten the service life of the equipment.

[0003] When rolling cabinet metal plates of different materials and thicknesses, it is impossible to quickly and accurately adjust the rolling parameters according to the specific rolling conditions. Moreover, the connection positions of key components such as the dowel rod and the piston rod are fixed, making it difficult to flexibly adjust according to actual conditions, making the equipment unable to cope with diverse production needs. The equipment is less sensitive to changes in rolling pressure and cannot respond to pressure changes in a timely manner and make corresponding adjustments, affecting the stability of the rolling process and the consistency of product quality.

[0014] A method for rolling a metal plate of an electric cabinet is also provided, comprising the following steps: S1: Preparation work, carefully check the connection of each component of the rolling device to ensure that all connections are firm and there is no sign of looseness or damage; at the same time, check the lubrication of each moving part, add lubricant, check the tension and wear of the transmission belt, and adjust the transmission position of the dowel rod according to the material and thickness parameters of the metal plate of the electric cabinet to be rolled; S2: Start the hydraulic cylinder to drive the roll frame to slide vertically in the vertical adjustment slot of the frame, so as to adjust the distance between the upper and lower rolls. Refer to the thickness of the metal plate to be rolled, combine empirical data or pre-set parameters, and adjust the roll spacing to a suitable value. During the adjustment process, the pressure detection sensor monitors the pressure change in real time to ensure accurate adjustment of the roll spacing; S3: Place the metal plate of the electric cabinet to be rolled between the upper and lower rollers, start the drive motor, and the drive motor drives the conical speed regulating wheel to rotate through the transmission belt, thereby driving the rollers to roll the metal plate.

[0015] The force transmission rod on the transmission plate transmits the pressure to the hydraulic damping cylinder, and transmits the force to the adjusting slider through the mechanical connecting rod. The adjusting slider slides on the first mounting frame through the first inclined slide groove, driving the adjusting transmission frame to move. The movement of the adjusting transmission frame changes the position of the transmission belt on the conical speed regulating wheel, thereby changing the effective diameter of the conical speed regulating wheel to achieve the adjustment of the roller speed.

[0016] S4: If more precise speed regulation is required, the speed fine-tuning component can be used to accurately change the position of the transmission belt on the conical speed regulating wheel to achieve fine-tuning of the roller speed. The tension maintaining component ensures that there is always appropriate friction between the belt and the conical speed regulating wheel to achieve stable transmission. The roller speed is continuously adjusted through the above-mentioned adaptive speed regulation mechanism to keep the rolling pressure within the predetermined appropriate range.

[0017] S5: After rolling is completed, close the hydraulic cylinder, reset the equipment, clean the rolling device, remove residual metal debris and oil stains, and maintain the equipment, such as re-lubricating moving parts, checking the connection of each component, and preparing for the next rolling.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses an adaptive speed regulating mechanism composed of a hydraulic damping cylinder, a mechanical connecting rod, an adjusting slider and a conical speed regulating wheel to automatically, quickly and accurately adjust the roller speed according to the change of rolling pressure. During the rolling process, the pressure change is converted into a speed regulating action through a series of mechanical linkages, without the need for a complex electronic control system. This not only greatly improves the rolling efficiency, but also avoids damage to the equipment caused by the mismatch between rolling speed and pressure, effectively prolongs the service life of the equipment, ensures the rolling quality of the metal plate of the electric cabinet, and reduces product defects caused by improper pressure.

[0019] 2. Multiple components work together to ensure the stability of the transmission. The tension holding component can automatically adjust the tension of the transmission belt in real time, so that the belt always fits tightly with the speed regulating wheel when the diameter of the conical speed regulating wheel changes, preventing the belt from slipping and ensuring the stable transmission of power. Adjusting the first clamping plate and the second clamping plate on the transmission frame can prevent the transmission belt from shifting and shaking during the speed regulation process, ensuring that the belt moves stably on the conical speed regulating wheel, further improving the stability of power transmission and the reliability of the operation of the entire rolling device.

[0020] 3. The present invention has flexible and precise adjustment functions. Through the speed fine-tuning assembly, the operator can finely adjust the roller speed by turning the screw column, meeting the strict requirements of different rolling processes on speed accuracy, and is particularly suitable for metal plate rolling with high requirements on dimensional accuracy and surface quality. At the same time, the adjustable locking assembly can easily adjust the connection position of the force transmission rod and the first piston rod, and reliably lock it, adapting to different rolling processes and working conditions, and enhancing the adaptability of the equipment to diversified production.

[0021] 4. The unique structural design of the hydraulic damping cylinder, which consists of the first hydraulic cylinder body and the second hydraulic cylinder body, realizes the amplification of the transmission distance. Even if the displacement change of the force transmission rod is small, it can be converted into a larger displacement of the fourth piston rod, so that the adjustment slider can more obviously change the transmission position diameter of the conical speed regulating wheel, and realize the precise adjustment of the roller speed. This not only improves the speed regulation accuracy, but also enhances the system's sensitivity to rolling pressure changes, so that the equipment can respond to pressure changes in time and adjust the roller speed, ensuring the stability and reliability of the rolling process, and helping to produce electric cabinet metal plate products that better meet quality requirements.

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1-10 The metal plate rolling device of the electric cabinet shown in the figure comprises a frame 1, wherein two upper and lower rollers 2 are arranged in the frame 1, the rollers 2 are mounted on the frame 1 through a bearing seat 3, a rolling shaft frame 4 is slidably arranged on the frame 1, the bearing seat 3 is mounted on the rolling shaft frame 4, a pressure sensor is fixedly mounted on the rolling shaft frame 4, a transmission plate 5 is slidably arranged on the rolling shaft frame 4, and a connecting spring 6 (such as Figure 6As shown in the figure, the four ends of the transmission plate 5 are connected by hydraulic transmission cylinders 38 installed on the bearing seat 3. The four groups of hydraulic transmission cylinders 38 are connected to each other by oil circuits and a first throttle valve 39 is provided at the connection point. A force transmission rod 7 is fixedly installed on the transmission plate 5. A transmission adjustment mechanism and an adaptive speed regulation mechanism are installed on the frame 1. The adaptive speed regulation mechanism includes a driving motor 8 and a speed regulation device. The transmission adjustment mechanism includes a hydraulic damping cylinder 9, a mechanical connecting rod 10 and an adjusting slider 11. The speed regulation device includes a first mounting frame 12, a conical speed regulation wheel 13 and The transmission belt 14, the hydraulic damping cylinder 9 and the first mounting frame 12 are all fixedly mounted on the frame 1, one end of the force transmission rod 7 is connected to the transmission plate 5, and the other end of the force transmission rod 7 is transmission-connected to the hydraulic damping cylinder 9, and the output end of the hydraulic damping cylinder 9 is transmission-matched with the adjusting slider 11 through the mechanical connecting rod 10, and two conical speed regulating wheels 13 are provided in opposite directions and are transmission-connected with the output end of the driving motor 8 and the shaft end of the roller 2 respectively, and the two conical speed regulating wheels 13 are driven by the transmission belt 14, and the adjusting slider 11 is transmission-matched with the transmission belt 14.

[0026] During the rolling process of the metal plate of the electric cabinet, the upper and lower rollers 2 apply rolling force to the metal plate. The pressure detection sensor installed on the rolling shaft frame 4 monitors the pressure condition in real time. As the use time increases, the rolling pressure of the roller 2 may change, which will cause the pressure on the hydraulic transmission cylinder 38 set on the bearing seat 3 to change accordingly. Thanks to the coordinated cooperation of the four groups of hydraulic transmission cylinders 38 and the first throttle valve 39, the transmission plate 5 elastically connected to the bearing seat 3 through the connecting spring 6 can be stably displaced under the drive of the hydraulic transmission cylinder 38, and the displacement amplitude of the transmission plate 5 is related to the change in the rolling pressure of the roller 2. At the same time, the force transmission rod 7 on the transmission plate 5 transmits the pressure to the hydraulic damping cylinder 9 on the frame 1. The hydraulic damping cylinder 9 changes the internal oil pressure according to the incoming pressure, and its output end accurately drives the adjustment slider 11 to move through the mechanical connecting rod 10. The adjusting slider 11 then drives the speed regulating device to work. When the adjusting slider 11 moves driven by the mechanical connecting rod 10, the position of the transmission belt 14 on the conical speed regulating wheel 13 will be changed, thereby changing the effective diameter of the conical speed regulating wheel 13. When the transmission belt 14 adjusts its position, the positions of both ends on the two conical speed regulating wheels 13 will be adjusted at the same time. For example, when the adjusting slider 11 makes the transmission belt 14 close to the end with a larger diameter of one of the conical speed regulating wheels 13, its effective diameter increases. At the same time, the effective diameter of the transmission position of the transmission belt 14 and the other conical speed regulating wheel 13 decreases. Since the driving motor 8 and the roller 2 form a transmission system through the conical speed regulating wheel 13 and the transmission belt 14, the change in the effective diameter of the conical speed regulating wheel 13 will cause the linear speed of the transmission belt 14 to change, thereby adjusting the rotation speed of the roller 2.

[0027] During the entire rolling process, the pressure applied by the roller 2 to the metal plate is transmitted to the hydraulic transmission cylinder 38 through the bearing seat 3, and then transmitted to the transmission plate 5 by the hydraulic transmission cylinder 38. The transmission plate 5 drives the transmission adjustment mechanism, which in turn enables the adaptive speed regulation mechanism to work. The adaptive speed regulation mechanism adjusts the speed of the roller 2 and readjusts the rolling pressure of the roller 2 on the metal plate (according to the rolling principle, the rolling pressure on the metal plate increases with an increase in the speed; the rolling pressure decreases with a decrease in the speed), thereby realizing the automatic adjustment function. This ensures that when producing the same type of electric cabinet metal plate, the equipment can automatically adjust the speed of the roller 2 according to the changes in the rolling pressure, and the rolling pressure is always controlled within the predetermined range by speed regulation, thereby improving product quality.

[0028] The pressure detection sensor continuously detects the pressure on the transmission plate 5 in real time, providing a detection standard for subsequent adjustment operations to ensure that the pressure during the rolling process is within an appropriate range. The force transmission rod 7 transmits the pressure to the hydraulic damping cylinder 9, causing the oil pressure in the cylinder to change. The oil pressure drives the mechanical connecting rod 10 to drive the adjusting slider 11. The adjusting slider 11 acts on the transmission belt 14 to change its position on the conical speed regulating wheel 13, thereby adjusting the effective diameter of the conical speed regulating wheel 13 and finally changing the speed of the roller 2. For example, when the rolling pressure increases, the hydraulic damping cylinder 9 pushes the mechanical connecting rod 10 to move the adjusting slider 11, changing the position of the transmission belt 14 on the conical speed regulating wheel 13, reducing the effective diameter of the conical speed regulating wheel 13 connected to the drive motor 8, and increasing the effective diameter of the conical speed regulating wheel 13 connected to the roller 2, and reducing the speed of the roller 2; conversely, when the rolling pressure decreases, the speed of the roller 2 increases.

[0029] This adaptive speed regulating mechanism composed of hydraulic damping cylinder 9, mechanical connecting rod 10, adjusting slide block 11 and conical speed regulating wheel 13 can automatically, quickly and accurately adjust the speed of roller 2 according to the rolling pressure change by relying on mechanical linkage only, without complex electronic control system. This method not only improves the rolling efficiency, but also avoids the damage to the equipment caused by the mismatch between rolling speed and pressure, prolongs the service life of the equipment, ensures the rolling quality of the metal plate of the electric cabinet, and reduces the product defects caused by improper pressure.

[0030] One end of one of the conical speed regulating wheels 13 is fixedly connected to the output end of the driving motor 8, and the other end is axially connected to the first mounting frame 12. One end of the other conical speed regulating wheel 13 is axially connected to the first mounting frame 12, and the other end passes through the first mounting frame 12 and is transmission-connected to the end of the roller 2. The outer side walls of the two conical speed regulating wheels 13 have the same inclination angle and are arranged in opposite directions. The transmission belt 14 is sleeved on the outer surface of the two conical speed regulating wheels 13. The speed regulating device also includes an adjusting transmission frame 15. The first mounting frame 12 is provided with a belt 15 which is the same as the outer side of the conical speed regulating wheel 13. The adjusting slider 11 is slidably arranged on the first mounting frame 12 through the first inclined slot 16, the adjusting transmission frame 15 is slidably arranged on the adjusting slider 11, the adjusting transmission frame 15 is transmission-connected to the transmission belt 14, a speed fine-tuning component is provided on the adjusting slider 11, the speed fine-tuning component is transmission-connected to the adjusting transmission frame 15, the sliding direction of the adjusting transmission frame 15 is consistent with the inclination direction of the first inclined slot 16, a tension maintaining component is also provided in the first mounting frame 12, and the tension maintaining component is transmission-connected to the transmission belt 14.

[0031] The speed fine-tuning assembly provided on the adjusting slide block 11 is in transmission connection with the adjusting transmission frame 15. When it is necessary to make a finer adjustment to the speed of the roller 2, the speed fine-tuning assembly can drive the adjusting transmission frame 15 to slide slightly on the adjusting slide block 11, further accurately change the position of the transmission belt 14 on the conical speed regulating wheel 13, and realize the fine adjustment of the speed of the roller 2. Regardless of how the diameter of the conical speed regulating wheel 13 changes, the tension holding assembly always applies appropriate tension to the transmission belt 14 to ensure effective transmission between the transmission belt 14 and the conical speed regulating wheel 13, and prevent problems such as belt slippage.

[0032] The hydraulic damping cylinder 9 is composed of a first hydraulic cylinder body 17 and a second hydraulic cylinder body 18 both mounted on the frame 1. The first hydraulic cylinder body 17 is provided with a first piston rod 19 and a second piston rod 20 (such as Figure 7 As shown), a third piston rod 21 and a fourth piston rod 22 are provided in the second hydraulic cylinder body 18, the first piston rod 19 is transmission connected to the force transmission rod 7, the second piston rod 20 is fixedly connected to the third piston rod 21 by a fixed connecting rod, and the fourth piston rod 22 is transmission connected to the mechanical connecting rod 10.

[0033] The first hydraulic cylinder body 17 is a first thin cylinder body, and the inner diameter of the first hydraulic cylinder body 17 in contact with the second piston rod 20 is smaller than the inner diameter of the first hydraulic cylinder body 17 in contact with the first piston rod 19. The second hydraulic cylinder body 18 is composed of a thick cylinder body and a second thin cylinder body. The third piston rod 21 is slidably arranged in the thick cylinder body, and the fourth piston rod 22 is slidably arranged in the second thin cylinder body.

[0034] The hydraulic damping cylinder 9 is designed to consist of a first hydraulic cylinder body 17 and a second hydraulic cylinder body 18. This design can achieve the amplification of the transmission distance, thereby ensuring that a small distance change of the force transmission rod 7 can also accurately adjust the position of the transmission belt 14, thereby realizing the speed adjustment function.

[0035] During the rolling process, when the pressure of the roller 2 changes, the force transmission rod 7 transmits the pressure to the first piston rod 19 in the first hydraulic cylinder body 17. After the first piston rod 19 is subjected to force, it is displaced in the first hydraulic cylinder body 17. Since the second piston rod 20 and the third piston rod 21 are fixedly connected by a fixed connecting rod, the displacement of the first piston rod 19 will drive the second piston rod 20 to move, and then the third piston rod 21 will be displaced in the second hydraulic cylinder body 18 through the fixed connecting rod. The displacement of the third piston rod 21 will cause the fourth piston rod 22 to move. The fourth piston rod 22 transmits force to the adjustment slider 11 through the mechanical connecting rod 10, thereby changing the transmission position of the transmission belt 14 on the two conical speed regulating wheels 13 in the speed regulating device, realizing the adjustment of the speed of the roller 2 to adapt to the change of rolling pressure, which is helpful to produce electric cabinet metal plate products that meet quality requirements.

[0036] When the force transmission rod 7 is subjected to pressure from the transmission plate 5, it transmits the pressure to the first piston rod 19 in the first fine cylinder body, thereby driving the second piston rod 20 to slide, and the sliding distance of the second piston rod 20 is greater than the transmission distance of the first piston rod 19. The second piston rod 20 drives the third piston rod 21 to move in the rough cylinder body through the fixed connecting rod, and the running displacement of the third piston rod 21 is consistent with the running displacement of the second piston rod 20. Due to the large cross-sectional area of ​​the rough cylinder body, the displacement of the third piston rod 21 in the rough cylinder body will drive the fourth piston rod 22 to slide in the second fine cylinder body, and the displacement of the fourth piston rod 22 is further amplified, realizing the amplification function of the transmission distance. The fourth piston rod 22 is then connected to the adjustment slider 11 through the mechanical connecting rod 10, and the force is transmitted to the adjustment slider 11, thereby adjusting the speed regulating device. The fourth piston rod 22 is connected to the adjustment slider 11 through the mechanical connecting rod 10, and the amplified displacement is converted into the movement of the adjustment slider 11, thereby realizing the adjustment of the speed regulating device, forming a complete mechanical transmission chain of pressure-displacement-speed regulation. Even if the displacement of the force transmission rod 7 changes slightly, the structural design of the hydraulic damping cylinder 9 can achieve a larger transmission distance amplification, making the entire speed control system more sensitive to changes in rolling pressure. It can respond to pressure changes in time and adjust the speed of the roller 2 to ensure the stability and reliability of the rolling process.

[0037] An adjustable locking assembly is provided at the connection between the force transmission rod 7 and the top of the first piston rod 19, and the adjustable locking assembly includes a locking nut 23, a locking sleeve 24 and a limit ring. The bottom of the force transmission rod 7 is hollow, and the top of the first piston rod 19 is slidably set in the hollow at the bottom of the force transmission rod 7. The locking nut 23 is rotatably installed on the outer wall of the bottom end of the force transmission rod 7, and the locking sleeve 24 is sleeved on the outer wall of the first piston rod 19. An external thread is provided on the outside of the first piston rod 19, and the first piston rod 19 is threadedly matched with the locking sleeve 24. The locking nut 23 is threadedly matched with the locking sleeve 24, and the limit ring is fixedly installed on the top of the first piston rod 19.

[0038] When the relative position of the force transmission rod 7 and the first piston rod 19 needs to be adjusted, the locking nut 23 is rotated, and the locking sleeve 24 is unlocked from the locking nut 23. At this time, the force transmission rod 7 can be relatively displaced with the first piston rod 19. When the position of the force transmission rod 7 and the first piston rod 19 needs to be locked, the locking sleeve 24 is rotated. Due to the threaded cooperation between the locking sleeve 24 and the first piston rod 19, the locking sleeve 24 can be driven to vertically displace on the first piston rod 19 when the locking sleeve 24 is rotated, and the locking sleeve 24 is displaced to the position to be locked. At this time, the locking nut 23 is threadedly connected with the locking sleeve 24. The tightening direction of the locking nut 23 is opposite to that of the locking sleeve 24. The outer side of the locking sleeve 24 is provided with an external thread threadedly connected with the locking nut 23. At this time, the locking nut 23, the locking sleeve 24, the first piston rod 19 and the force transmission rod 7 are connected and locked into one body, thereby realizing the overall locking function. Prevent the first piston rod 19 from coming out of the hollow at the bottom of the force transmission rod 7, and ensure the stability of pressure transmission.

[0039] The adjustable connection mode can adapt to the requirements for the connection position of the force transmission rod 7 and the first piston rod 19 under different rolling processes and working conditions, thereby enhancing the adaptability of the equipment to diversified production needs.

[0040] A second throttle valve 25 (such as Figure 3 as shown).

[0041] The second throttle valve 25 controls the flow of oil, so that the oil pressure in the hydraulic damping cylinder 9 changes more smoothly. The smooth oil pressure change is transmitted to the adjustment slider 11 through the mechanical connecting rod 10, and the adjustment slider 11 stably drives the speed regulating device to work, changes the position of the transmission belt 14 on the conical speed regulating wheel 13, and then stably adjusts the speed of the roller 2.

[0042] The speed fine-tuning assembly includes a fine-tuning screw 26, a screw column 27, a fine-tuning seat 28 and a locking bolt. The fine-tuning screw 26 is rotatably installed on the adjusting slider 11. The length direction of the fine-tuning screw 26 is consistent with the length direction of the first inclined slide groove 16. The end of the fine-tuning screw 26 is fixedly connected to the screw column 27. The fine-tuning seat 28 is slidably set on the adjusting slider 11. The fine-tuning seat 28 is threadedly matched with the fine-tuning screw 26. The locking bolt is installed at the end of the fine-tuning screw 26 away from the screw column 27.

[0043] Initial state: When the electric cabinet metal plate rolling device works normally, the adjusting slide block 11 slides on the first mounting frame 12 through the first inclined slide slot 16, driving the adjusting transmission frame 15 to change the position of the transmission belt 14 on the conical speed regulating wheel 13, thereby realizing the preliminary adjustment of the speed of the roller 2. At this time, the speed fine-tuning component is in a standby state.

[0044] Fine-tuning operation: When it is necessary to make a finer adjustment to the speed of the roller 2, the operator rotates the screw column 27. Since the fine-tuning screw 26 is fixedly connected to the screw column 27, the rotation of the screw column 27 drives the fine-tuning screw 26 to rotate on the adjustment slider 11. Since the fine-tuning seat 28 is threadedly matched with the fine-tuning screw 26 and is slidably arranged on the adjustment slider 11, the rotation of the fine-tuning screw 26 causes the fine-tuning seat 28 to move linearly along the length direction of the fine-tuning screw 26 (i.e., the length direction of the first inclined slide 16). The movement of the fine-tuning seat 28 drives the adjustment transmission frame 15 connected thereto to slide slightly on the adjustment slider 11. The adjustment transmission frame 15 is connected to the transmission belt 14 in transmission, and its slight sliding will further accurately change the position of the transmission belt 14 on the conical speed regulating wheel 13, thereby realizing the fine-tuning of the speed of the roller 2. After adjusting to a suitable rotation speed, the operator uses a locking bolt to fix the fine-tuning screw 26 to prevent the fine-tuning screw 26 from rotating due to factors such as vibration during the rolling process, thereby ensuring the stability of the position after fine-tuning and maintaining the accuracy of the rotation speed of the roller 2.

[0045] The speed fine-tuning assembly can finely adjust the speed of the roller 2 to meet the strict requirements of the speed accuracy of the metal plate rolling process of different cabinets. When rolling some metal plates with high dimensional accuracy and surface quality requirements, accurate speed adjustment helps to improve product quality. The speed can be fine-tuned by turning the screw column 27, which is simple and convenient to operate. Moreover, it can be adjusted at any time according to the actual rolling situation, which has strong flexibility.

[0046] The tension maintaining assembly includes a second mounting frame 29, a tension roller 30, a tension spring 31, an adjusting bolt 32 and a second guide column 33. The second mounting frame 29 is installed in the first mounting frame 12, the tension roller 30 is rotatably installed on the second mounting frame 29, the length direction of the tension roller 30 is consistent with the direction of the first inclined slide groove 16, one end of the tension spring 31 is fixedly connected to the first mounting frame 12, the other end of the tension spring 31 is fixedly connected to the second mounting frame 29, the adjusting bolt 32 is rotatably installed on the second mounting frame 29, the adjusting bolt 32 is threadedly connected to the first mounting frame 12, the second guide column 33 is fixedly installed on the first mounting frame 12, and the adjusting bolt 32 is slidably set in the second guide column 33.

[0047] Before the electric cabinet metal plate rolling device starts working, the operator can adjust the preload force of the tension spring 31 by turning the adjusting bolt 32. Since the adjusting bolt 32 is threadedly connected to the first mounting frame 12, when the adjusting bolt 32 is turned, it will slide in the second guide column 33, driving the second mounting frame 29 to move relative to the first mounting frame 12, thereby stretching or compressing the tension spring 31 and setting the initial tension of the transmission belt 14.

[0048] Tension adjustment during rolling: During the rolling process, as the diameter of the conical speed regulating wheel 13 changes, the tension of the transmission belt 14 will change. When the tension of the transmission belt 14 increases, the pressure of the belt on the tension roller 30 increases, which will cause the second mounting frame 29 to move in the direction of compressing the tension spring 31. The tension spring 31 will produce a reverse elastic force to resist this movement, thereby stabilizing the belt tension. Conversely, when the tension of the transmission belt 14 decreases, the elastic force of the tension spring 31 will push the second mounting frame 29, so that the tension roller 30 applies greater pressure to the belt, increasing the belt tension, ensuring that there is always appropriate friction between the belt and the conical speed regulating wheel 13, and achieving stable transmission. During the entire rolling process, the tension holding assembly is constantly dynamically adjusted according to the change of the belt tension. The tension spring 31 automatically adjusts the pressure of the tension roller 30 on the transmission belt 14 through expansion and contraction deformation, so that the belt tension is always maintained within an appropriate range, ensuring the stable operation of the device.

[0049] The tension maintaining component can automatically adjust the tension of the transmission belt 14 in real time, so that the belt always fits tightly with the conical speed regulating wheel 13 when the diameter of the conical speed regulating wheel 13 changes, avoiding the occurrence of belt slippage, ensuring the stable transmission of power, and improving the stability and reliability of the rolling process.

[0050] A first clamping plate 34 and a second clamping plate 35 are installed on the adjusting transmission frame 15. The first clamping plate 34 is fixedly installed at the center of the adjusting transmission frame 15. The second clamping plate 35 is provided with two groups and is fixedly installed at both ends of the adjusting transmission frame 15 respectively. The first clamping plate 34 is provided with a limiting sliding groove 36 for limiting the transmission belt 14, and the second clamping plate 35 is provided with a clamping wheel 37 that fits with the transmission belt 14.

[0051] When the adjusting slider 11 slides in the first inclined slide groove 16 and drives the adjusting transmission frame 15 to move, the first clamping plate 34 and the second clamping plate 35 on the adjusting transmission frame 15 move accordingly. The limiting sliding groove 36 at the center of the first clamping plate 34 limits the transmission belt 14 to ensure that the transmission belt 14 does not deviate from the normal transmission path during the movement. At the same time, the clamping wheel 37 on the second clamping plate 35 fits tightly with the transmission belt 14. As the adjusting transmission frame 15 moves, the clamping wheel 37 can assist the transmission belt 14 to move smoothly on the conical speed regulating wheel 13, and further prevent the belt from shaking or deviating. During the entire rolling process, as the speed of the roller 2 is adjusted, the position of the transmission belt 14 on the conical speed regulating wheel 13 changes continuously. The first clamping plate 34 and the second clamping plate 35 continue to play a role, the limiting sliding groove 36 always limits the belt, and the clamping wheel 37 always fits with the belt, ensuring the stability of the transmission belt 14 during the speed regulation process, so that the belt can accurately transmit the power of the driving motor 8 to the roller 2, realizing a stable rolling process.

[0052] Improve transmission stability: The setting of the first clamping plate 34 and the second clamping plate 35 effectively prevents the transmission belt 14 from deflecting and shaking during the speed regulation process, so that the belt can move stably on the conical speed regulating wheel 13, ensuring the stability of power transmission between the drive motor 8 and the roller 2, thereby improving the operating stability and reliability of the entire rolling device.

[0053] A method for rolling a metal plate of an electric cabinet comprises the following steps: S1: Preparation work, carefully check the connection of each component of the rolling device to ensure that all connections are firm and there is no sign of looseness or damage; at the same time, check the lubrication of each moving part, add lubricant, check the tension and wear of the transmission belt 14, and adjust the transmission position of the force transmission rod 7 according to the material and thickness parameters of the metal plate of the electric cabinet to be rolled; S2: Start the hydraulic cylinder to drive the roll frame 4 to slide vertically in the vertical adjustment slot of the frame 1, so as to adjust the distance between the upper and lower rolls 2. Refer to the thickness of the metal plate to be rolled, combine empirical data or pre-set parameters, and adjust the distance between the rolls 2 to a suitable value. During the adjustment process, the pressure change is monitored in real time through the pressure detection sensor to ensure that the distance between the rolls 2 is adjusted accurately; S3: placing the electric cabinet metal plate to be rolled between the upper and lower rollers 2, starting the drive motor 8, and driving the conical speed regulating wheel 13 to rotate through the transmission belt 14, thereby driving the rollers 2 to roll the metal plate.

[0054] The force transmission rod 7 on the transmission plate 5 transmits the pressure to the hydraulic damping cylinder 9, and transmits the force to the adjusting slider 11 through the mechanical connecting rod 10. The adjusting slider 11 slides on the first mounting frame 12 through the first inclined slide groove 16, driving the adjusting transmission frame 15 to move. The movement of the adjusting transmission frame 15 changes the position of the transmission belt 14 on the conical speed regulating wheel 13, thereby changing the effective diameter of the conical speed regulating wheel 13, thereby realizing the adjustment of the rotation speed of the roller 2.

[0055] S4: If more precise speed regulation is required, the speed fine-tuning component can be used to accurately change the position of the transmission belt 14 on the conical speed regulating wheel 13 to achieve fine-tuning of the speed of the roller 2. The tension maintaining component ensures that there is always appropriate friction between the belt and the conical speed regulating wheel 13 to achieve stable transmission. The speed of the roller 2 is continuously adjusted through the above-mentioned adaptive speed regulation mechanism to keep the rolling pressure within the predetermined appropriate range.

[0056] S5: After rolling is completed, close the hydraulic cylinder, reset the equipment, clean the rolling device, remove residual metal debris and oil stains, and maintain the equipment, such as re-lubricating moving parts, checking the connection of each component, and preparing for the next rolling.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
