Description

Technical Field

[0001] This invention relates to the field of rolling machine technology, and more specifically, to an automatic rolling machine for water tower production. Background Technology

[0002] Water towers, as water storage containers, are typically made of rolled and welded metal sheets such as stainless steel, and their bodies are relatively long and have a large diameter. To improve the structural strength of the tank body and prevent radial deformation or collapse after being filled with water, several circumferential reinforcing ribs are usually rolled and processed on the surface of the tank body.

[0003] Currently, in the field of metal drum and can processing, existing automatic ribbing machines typically include a frame, a movable platform, and upper and lower ribbing rollers mounted on the frame. Their working principle involves using the upper and lower ribbing rollers to press against the drum wall in opposite directions, and relying on the friction between the drum and the rollers to drive the drum to rotate, thereby forming a circumferential concave rib on the outer wall of the drum.

[0004] However, existing rolling machines generally adopt a single-stage forming design, meaning that each time the machine is started, only one reinforcing rib can be rolled and processed on the barrel body. For long barrel products such as water towers that require multiple reinforcing ribs, this single-stage forming method has the following inherent drawbacks: The process is cumbersome and the production efficiency is low: after the operator completes the processing of one rib, he / she needs to stop the machine and manually adjust the axial position of the tank body on the equipment, and then start again to roll the next rib. This process is repeated many times, which means that processing a water tower tank body requires multiple clamping and positioning. The process is lengthy and seriously restricts the output efficiency of the production line.

[0005] High labor intensity and high labor costs: Frequent manual intervention and workpiece handling and adjustment increase the workload of operators and require a high level of skill from them, which is not conducive to enterprises reducing production costs and achieving automation upgrades.

[0006] Processing accuracy is difficult to guarantee: Multiple clamping and manual positioning can easily lead to cumulative errors, resulting in uneven spacing between adjacent reinforcing ribs, and even misalignment or uneven depth of rib patterns, which directly affects the structural strength consistency and appearance quality of water tower products.

[0007] Therefore, how to overcome the shortcomings of existing rolling machines that cannot complete the processing of multiple reinforcing ribs in water towers in one go, and develop a device that can continuously complete the rolling forming of multiple ribs, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0008] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automatic rolling machine for water tower production, so as to solve the defects existing in the above-mentioned background technology.

[0009] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automatic rolling machine for water tower production, comprising: frame; The processing platform is set on the frame for placing the barrels; The rib rolling assembly, mounted on the frame, is used to perform rib rolling on the barrel body on the processing platform. An adjustment component, mounted on the frame, is used to adjust the position of the rib rolling assembly to process barrels of different specifications; Clamping components are mounted on the processing platform to fix the barrel body; The compensation component, mounted on the frame, is used to detect whether the barrel is clamped during the rolling process and to compensate for the barrel to clamp it if it is not clamped. Drive components are used to move the barrel along the processing platform; The control system is used to operate the above components and has an operation panel mounted on the rack. The ribbing assembly includes a motor mounted on a frame, a first ribbing wheel set, a second ribbing wheel set, and a main ribbing wheel set disposed on the frame. The output end of the motor is fixedly connected to a drive shaft arranged along the length of the processing platform. The first ribbing wheel set includes first ribbing wheels rotatably connected to the upper and lower sides of the frame. The second ribbing wheel set includes second ribbing wheels rotatably connected to the upper and lower sides of the frame. The main ribbing wheel set includes a main ribbing wheel rotatably connected to the upper and lower sides of the frame and located between the first and second ribbing wheels. Several mounting seats are installed on the processing platform for the drive shaft to rotate. The first ribbing wheel, second ribbing wheel, and main ribbing wheel set located below... The rib roller and the main rib roller are fixedly connected to the drive shaft. The adjustment assembly includes several sets of motors and several adjustment rods. The output end of the motor is fixedly connected to a drive gear. The adjustment rod is rotatably connected to the frame and a driven gear is fixedly connected to its side wall. The drive gear and the driven gear are connected by a transmission chain. A threaded rod is threaded to the top of the adjustment rod. A drive plate is fixedly connected to the side wall of the threaded rod. Two connecting rods that penetrate the frame to the top of the processing platform are fixedly connected to the drive plate. The end of the connecting rod away from the drive plate is fixedly connected to a mounting platform for the rotation of the first rib roller, the second rib roller, and the main rib roller.

[0010] By adopting the above technical solution, the barrel to be processed is placed on the processing platform. Then, the clamping assembly is fixed to the barrel using the control system via the operation panel. Next, motor one is started using the operation panel, causing the drive shaft fixed at its output end to rotate. This, in turn, drives the first, second, and main rolling wheels on the drive shaft to rotate. Then, the output end of motor two is driven to rotate via the operation panel. Simultaneously, the drive gear rotates along with it, and through the transmission chain, it drives the driven gear to rotate, thereby driving the adjusting rod to rotate. Because the threaded rod is threadedly connected to the adjusting rod, and the drive plate and connecting rod restrict the rotation of the threaded rod, the threaded rod will move along the axial direction of the adjusting rod when it rotates. Since the drive plate is fixedly connected to the threaded rod, and the connecting rod is fixedly connected to the drive plate, the drive plate and connecting rod will move together when the threaded rod moves. After the connecting rod moves, the connected... The mounting table moves along with the main roller, which in turn moves the first roller, the second roller, and the main roller, changing their positions to match the roller assembly's dimensions with the barrel's specifications. Once the first roller, the second roller, and the main roller on the mounting table are aligned with the first roller, the second roller, and the main roller on the drive shaft, the roller forming process begins. During this process, the compensation component detects whether the barrel is clamped and compensates to clamp it if not, ensuring subsequent processing proceeds normally. After the reinforcing ribs at a certain point on the barrel are processed, the mounting table is moved away from the barrel using the control panel. Then, the drive assembly is used to adjust the barrel's position to move it to the next processing position, and the above process is repeated. The entire processing can be completed using a preset control system and the control panel, reducing labor costs and improving overall processing efficiency.

[0011] The present invention is further configured such that: the clamping assembly includes a mounting frame mounted on a processing platform, a mounting rod rotatably connected to the mounting frame, a guide rail fixedly connected to the mounting frame, and a motor connected to a control system; a movable plate is slidably connected between the mounting rod and the guide rail; two clamping plates are fixedly connected to the mounting rod, one side of which is fixed to the movable plate; and the movable plate is threadedly connected to the output shaft of the motor.

[0012] By adopting the above technical solution, after the barrel is placed on the processing platform, one side of the barrel is abutted against the side of the clamping plate away from the motor three. Then, the control system drives the output shaft of the motor three to rotate, which drives the moving plate connected to it to move, and then drives the clamping plate to move, so that the clamping plate abuts against the other side of the barrel, thereby achieving the effect of clamping the barrel. After the barrel is processed, the motor three is driven to reverse, and the barrel can then be removed.

[0013] The present invention is further configured such that: the compensation component includes a detection component and an execution component; when the detection component detects that the barrel is not clamped during processing, it triggers the execution component to run a signal to clamp the barrel.

[0014] By adopting the above technical solution, during the barrel processing, the side wall of the barrel will undergo plastic deformation, resulting in a shortening of the axial dimension of the barrel, which in turn causes the barrel to not be clamped. After the detection component detects this state, it will transmit the running signal to the execution component. After the execution component is triggered, it will clamp the barrel to avoid affecting subsequent processing.

[0015] The invention is further configured such that: the detection component includes a clamping block installed on the clamping plate facing the barrel, the clamping block has a positioning groove for the barrel to be inserted, and a pressure sensor connected to the control system is provided on the inner wall of the positioning groove. When the barrel is inserted into the positioning groove and abuts against the bottom of the positioning groove, the barrel abuts against the pressure sensor. When the barrel is separated from the pressure sensor, the pressure sensor transmits an action signal to the execution component through the control system.

[0016] By adopting the above technical solution, after the barrel is inserted into the positioning groove, the barrel will come into contact with the pressure sensor. At this time, the actuator does not receive an action signal and does not work. However, after the axial dimension of the barrel is shortened during the processing, the barrel will separate from the pressure sensor. When it separates, the pressure sensor will transmit the action signal to the actuator through the control system. After the actuator is triggered, it will clamp the barrel to avoid affecting subsequent processing.

[0017] The present invention is further configured such that: the execution component includes a plurality of electric telescopic rods mounted on the clamping block and connected to the control system; the output end of the electric telescopic rod is fixedly connected to a clamping plate; a groove is provided on the inner wall of the clamping block; the clamping plate is located in the groove; when the signal detected by the pressure sensor is less than the preset pressure value in the control system, the control system drives the output end of the electric telescopic rod to extend and drive the clamping plate to clamp the barrel.

[0018] By adopting the above technical solution, the pressure value when the barrel body comes into contact with the pressure sensor is set to a preset pressure value. During the processing, when the axial dimension of the barrel body shortens, the barrel body will gradually separate from the pressure sensor. At this time, the signal detected by the pressure sensor is less than the preset pressure value in the control system. The control system drives the output end of the electric telescopic rod to extend, driving the clamping plate to move towards one side of the barrel body until the clamping plate comes into contact with the barrel body, thereby clamping and fixing the barrel body in the positioning groove.

[0019] The present invention is further configured such that: the drive assembly includes a motor four mounted on the bottom of the processing platform and controlled by the control system, and a screw fixedly connected to the output end of the motor four; a plurality of connecting plates are fixedly connected on the mounting bracket, and at least one of the connecting plates is fixedly connected to a connecting seat; the screw is threadedly connected to the connecting seat.

[0020] By adopting the above technical solution, after the control system drives the fourth motor to work, the output end of the fourth motor will drive the screw to rotate, thereby driving the connecting seat that is threaded to it to move along the screw axis. Since the connecting seat and the connecting plate are fixed to each other, and the connecting plate and the mounting bracket are fixed to each other, the mounting bracket will also move accordingly.

[0021] The present invention is further configured such that: a plurality of tracks are fixedly connected to the bottom of the processing platform, and guide blocks matching the tracks are fixedly connected to the connecting plate.

[0022] By adopting the above technical solution, the position of the mounting frame is prevented from shifting during the movement along the processing platform. At the same time, the smoothness of the mounting frame sliding can be improved by the cooperation of the guide block and the track.

[0023] The present invention is further configured such that: the control system is equipped with an automatic cyclic processing mode. In the automatic cyclic processing mode, the control system controls the drive component to move the barrel to multiple preset processing positions in sequence, and controls the rolling component to complete the rolling forming of a reinforcing rib at each processing position until all reinforcing ribs on the barrel are processed.

[0024] By adopting the above technical solution, the control system enables the barrel to continuously roll-form multiple reinforcing ribs after one clamping by preset processing position and automatic cycle control, without the need for manual adjustment of the barrel position multiple times, effectively shortening the processing cycle, while ensuring the consistency of the spacing between adjacent reinforcing ribs.

[0025] The present invention is further configured such that: the control system includes a comparison module, which is used to compare the real-time pressure value detected by the pressure sensor with a preset pressure threshold. When the real-time pressure value is lower than the preset pressure threshold, the control system sends a start signal to the electric telescopic rod to extend the clamping plate to re-clamp the barrel. When the pressure value detected by the pressure sensor recovers to above the preset pressure threshold, the control system controls the electric telescopic rod to maintain the current clamping state.

[0026] By adopting the above technical solution, the comparison module realizes real-time monitoring and closed-loop control of the barrel clamping status. When the barrel axially shortens due to the rolling process, clamping compensation is automatically triggered, avoiding the problem of the rolling quality being affected by the loosening of the barrel, and further improving the stability of the processing process and the finished product qualification rate.

[0027] In summary, the present invention has the following beneficial effects: 1. By setting up a control system that is electrically connected to motor 1, motor 2, motor 3, motor 4, electric telescopic rod and pressure sensor respectively, the entire process from barrel clamping, rolling wheel height adjustment, rolling processing to barrel displacement and clamping compensation is fully automated, reducing manual intervention and significantly improving processing efficiency and control accuracy. Second, by configuring an automatic cycle processing mode, the barrel can continuously complete the processing of multiple reinforcing ribs after one clamping, without the need for manual adjustment of the barrel position multiple times, effectively shortening the processing cycle, while ensuring the consistency of the spacing between adjacent reinforcing ribs.

It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] Automatic rolling machines for water tower production, such as Figures 1-6 As shown, the device includes a frame 1, a processing platform 2 mounted on the frame 1 for placing the barrel, a rib rolling assembly for rib rolling, an adjustment assembly for adjusting the position of the rib rolling assembly, a clamping assembly for fixing the barrel, a compensation assembly for detecting and compensating for the clamping state of the barrel, a drive assembly for driving the barrel to move along the processing platform 2, and a control system for operating the above components. The control system has an operation panel 3 mounted on the frame 1, which facilitates manual setting of parameters and starting and stopping of the equipment.

[0034] like Figures 1-3 As shown, the rib rolling assembly includes a motor 4 mounted on the frame 1, a first rib rolling wheel group, a second rib rolling wheel group, and a main rib rolling wheel group mounted on the frame 1. The output end of the motor 4 is fixedly connected to a drive shaft 5 arranged along the length of the processing platform 2. Several mounting seats 9 are mounted on the processing platform 2 for the drive shaft 5 to rotate. The first rib rolling wheel group includes a first rib rolling wheel 6 rotatably connected to the upper and lower sides of the frame 1. The second rib rolling wheel group includes a second rib rolling wheel 7 rotatably connected to the upper and lower sides of the frame 1. The main rib rolling wheel group includes a main rib rolling wheel 8 rotatably connected to the upper and lower sides of the frame 1 and located between the first rib rolling wheel 6 and the second rib rolling wheel 7. The lower first rib rolling wheel 6, the second rib rolling wheel 7, and the main rib rolling wheel 8 are fixedly connected to the drive shaft 5 and are driven to rotate synchronously by the motor 4. The upper first rib rolling wheel 6, the second rib rolling wheel 7, and the main rib rolling wheel 8 are mounted on the mounting table 18 and can be raised and lowered with the mounting table 18.

[0035] like Figures 1-4As shown, the adjustment assembly includes several sets of motors 10 and several adjustment rods 11. The output end of the motors 10 is fixedly connected to a drive gear 12. The adjustment rods 11 are rotatably connected to the frame 1 and a driven gear 13 is fixedly connected to the side wall. The drive gear 12 and the driven gear 13 are connected by a transmission chain 14. The top of the adjustment rod 11 is threadedly connected to a threaded rod 15. A drive plate 16 is fixedly connected to the side wall of the threaded rod 15. Two connecting rods 17 that pass through the frame 1 to the processing platform 2 are fixedly connected to the drive plate 16. The end of the connecting rod 17 away from the drive plate 16 is fixedly connected to a mounting platform 18 for the first rolling wheel 6, the second rolling wheel 7, and the main rolling wheel 8 to rotate.

[0036] During actual adjustment, motor 10 drives driven gear 13 and adjusting rod 11 to rotate through drive gear 12 and transmission chain 14. Threaded rod 15 moves up and down along adjusting rod 11 under the circumferential limiting action of drive plate 16 and connecting rod 17, thereby driving the mounting platform 18 and the first rolling wheel 6, second rolling wheel 7 and main rolling wheel 8 above it to move up and down as a whole to adapt to barrels of different diameters.

[0037] like Figures 1-6 As shown, the clamping assembly includes a mounting frame 19 mounted on the processing platform 2, a mounting rod 20 rotatably connected to the mounting frame 19, a guide rail 21 fixedly connected to the mounting frame 19, and a motor 22 connected to the control system. A movable plate 23 is slidably connected between the mounting rod 20 and the guide rail 21. Two clamping plates 24 are fixedly connected to the mounting rod 20. One side of one clamping plate 24 is fixed to the movable plate 23. The movable plate 23 is threadedly connected to the output shaft of the motor 22. After the barrel is placed on the processing platform 2, one side of it abuts against the clamping plate 24 away from the motor 22. The control system controls the output end of the motor 22 to extend, pushing the other clamping plate 24 and the movable plate 23 to slide along the guide rail 21, thereby clamping the barrel.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the compensation component includes a detection component and an execution component, which are used to automatically compensate for clamping when the barrel body is shortened axially due to plastic deformation during the rolling process. The detection component includes a clamping block 25 installed on the clamping plate 24 facing the barrel body. The clamping block 25 has a positioning groove 26 for the barrel body to be inserted. A pressure sensor 27 connected to the control system is provided on the inner wall of the positioning groove 26. When the barrel body is inserted into the positioning groove 26 and abuts against the bottom of the groove, the barrel body abuts against the pressure sensor 27. At this time, the pressure value detected by the pressure sensor 27 is a preset pressure threshold.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the actuating components include several electrically operated telescopic rods 28 mounted on the clamping block 25 and connected to the control system. The output ends of the electrically operated telescopic rods 28 are fixedly connected to clamping plates 29. A groove 30 is formed on the inner wall of the clamping block 25, and the clamping plates 29 are located within the groove 30. The control system has a built-in comparison module used to compare the real-time pressure value detected by the pressure sensor 27 with a preset pressure threshold. When the real-time pressure value is lower than the preset pressure threshold, the control system sends a start signal to the electrically operated telescopic rods 28, causing the clamping plates 29 to extend and re-clamp the barrel. When the pressure value detected by the pressure sensor 27 recovers to above the preset pressure threshold, the control system maintains the current clamping state of the electrically operated telescopic rods 28 to avoid over-clamping. This comparison module can be implemented by comparison instructions in a programmable logic controller (PLC), an analog quantity comparison program in a microcontroller, or an independent voltage comparator circuit. The specific control logic is as follows: (a) Setting the preset pressure threshold During the initial clamping stage of the barrel, when the clamping assembly pushes both ends of the barrel into the positioning grooves 26 of the clamping blocks 25 on both sides and abuts against the bottom of the grooves, the side wall of the barrel applies pressure to the pressure sensor 27 installed on the inner wall of the positioning groove 26. At this time, the control system reads the initial pressure value of the pressure sensor 27, multiplies this value by a set reliability coefficient (usually 0.8 to 0.9), and determines it as the preset pressure threshold, which is stored in the internal memory of the control system. For continuous processing of barrels of the same specification, the operator can choose to use the previously set threshold or manually input the threshold value through the operation panel 3. In addition, the control system also allows setting the pressure threshold corresponding to each reinforcing rib in the debugging mode to adapt to the clamping requirements of different processing stages.

[0040] (ii) Continuous monitoring of real-time pressure values During the rolling process, the control system continuously reads the real-time pressure value fed back by the pressure sensor 27 using a high-frequency sampling method with a sampling period of no more than 100 milliseconds. The pressure sensor 27 adopts a thin-film or strain gauge structure and is installed in the middle of the inner wall of the positioning groove 26 to ensure that it can sensitively reflect the change in contact pressure between the barrel and the pressure sensor 27 when the barrel is axially shortened. The sampled real-time pressure value is converted into a digital signal by the analog input module and then sent to the comparison module for comparison with the preset pressure threshold.

[0041] (III) Comparison Logic and Triggering Mechanism The comparison module employs hysteresis comparison logic to avoid frequent start-stop of the electric telescopic rod 28 due to minor fluctuations in the pressure signal. Specifically, when the comparison module detects that the real-time pressure value is lower than the preset pressure threshold and the duration exceeds the set delay time, such as 0.3 seconds, it determines that the barrel has axially shortened and loosened, and then outputs an "insufficient pressure" signal to the control system. Upon receiving this signal, the control system immediately sends a start signal to the electric telescopic rod 28, controlling the output end of the electric telescopic rod 28 to extend and push the clamping plate 29 out of the groove 30 of the clamping block 25 toward the side wall of the barrel, applying supplementary clamping force to the barrel.

[0042] (iv) Maintaining the clamping state after pressure recovery As the clamping plate 29 extends, the barrel is re-pressurized, and the real-time pressure value detected by the pressure sensor 27 rises accordingly. When the comparison module detects that the real-time pressure value has recovered to above the preset pressure threshold and has remained stable for more than the set confirmation time (e.g., 0.5 seconds), it determines that the barrel has returned to a reliable clamping state. At this time, the control system sends a stop signal to the electric telescopic rod 28, keeping the output end of the electric telescopic rod 28 in its current position, and the clamping plate 29 maintains its current extension amount without further pressing. This "holding" state is achieved by controlling the bidirectional self-locking valve in the air circuit of the electric telescopic rod 28 or by maintaining the piston position after the control solenoid valve is de-energized, thus avoiding excessive deformation of the barrel or damage to the pressure sensor 27 due to continuous pressurization.

[0043] (v) Mechanism for handling abnormal situations During the extension compensation process of clamping plate 29, if the output end of electric telescopic rod 28 reaches its maximum stroke but the real-time pressure value still does not recover to above the preset pressure threshold, the control system determines that the barrel may have abnormal misalignment or the clamping block 25 may have failed to position. It immediately stops the rolling process, issues an audible and visual alarm, and displays the message "Clamping compensation failed" on the operation panel 3, waiting for manual inspection and intervention. In addition, if the comparison module detects that the real-time pressure value is higher than the upper limit of the preset pressure threshold for a long time, such as 1.2 times the initial value, the control system will also issue an alarm to prevent the barrel from being crushed or the equipment from being overloaded due to excessive clamping force.

[0044] (vi) Synergy with automated cyclic processing mode In the automatic cycle processing mode, the clamping compensation mechanism of the comparison module is always active. During the roll forming process of each reinforcing rib, the control system continuously performs pressure comparison and compensation control in the background without interrupting the automatic cycle. When a reinforcing rib is processed and the barrel is moved to the next position, the comparison module continues to monitor to ensure that the barrel is always in a stable clamping state throughout the entire multi-rib processing cycle, avoiding the impact of multiple shifts on the accuracy of subsequent processing.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, the drive assembly includes a motor 31 mounted on the bottom of the processing platform 2 and controlled by the control system, and a screw 32 fixedly connected to the output end of the motor 31. Several connecting plates are fixedly connected to the mounting frame 19, and at least one connecting plate is fixedly connected to a connecting seat 33. The screw 32 is threadedly connected to the connecting seat 33. Several tracks 34 are fixedly connected to the bottom of the processing platform 2, and guide blocks 35 matching the tracks 34 are fixedly connected to the connecting plates to ensure the straightness and stability of the mounting frame 19 during movement. When the motor 31 drives the screw 32 to rotate, the connecting seat 33 drives the mounting frame 19 and the clamping assembly to move along the length of the processing platform 2, thereby sequentially sending the barrel to each preset processing position.

[0046] The control system is equipped with an automatic cyclic processing mode. In this mode, the control system controls the drive assembly to move the barrel sequentially to multiple preset processing positions, and at each position, controls the rolling assembly to roll-form one reinforcing rib until all reinforcing ribs on the barrel are processed. Throughout the process, the lifting and lowering of the first rolling wheel 6 / second rolling wheel 7 / main rolling wheel 8, the displacement of the barrel, clamping, and compensation are all automatically executed by the control system according to a preset program, eliminating the need for manual repeated clamping and positioning. This mode is executed by a programmable logic controller or industrial control computer built into the control system. The operator activates it via the mode selection button on the operation panel 3. In the automatic cyclic processing mode, the control system automatically completes the continuous rolling forming of multiple reinforcing ribs on the barrel according to the preset processing parameters and process flow. The specific implementation method is as follows: (a) Setting the preset processing position Before processing a water tower tank of a certain specification for the first time, the operator inputs the number of reinforcing ribs to be processed and the axial position coordinates of each rib relative to the end face of the tank through the operation panel 3. The control system converts these position coordinates into the movement distance parameters of the drive components and stores them in the internal memory in the form of a table, forming a preset processing position sequence. For subsequent processing of tanks of the same specification, the operator can directly call the stored processing formula without repeating the settings.

[0047] (ii) Barrel displacement and positioning control After one reinforcing rib is rolled, the control system sends a shift command to the drive assembly. Specifically, the control system controls motor 31 to run in a preset direction and rotation amount. Motor 31 drives screw 32 to rotate, and drives mounting bracket 19 to move along the length of processing platform 2 through connecting seat 33 and connecting plate. The moving distance of mounting bracket 19 is controlled by the control system through closed-loop control via pulse counting or encoder feedback to ensure that the barrel is accurately moved to the preset processing position of the next rib. During the shifting process, the control system controls the adjustment assembly to make the mounting table 18 drive the first rib rolling wheel 6, the second rib rolling wheel 7, and the main rib rolling wheel 8 above to rise, so that the first rib rolling wheel 6, the second rib rolling wheel 7, and the main rib rolling wheel 8 are out of contact with the surface of the barrel, avoiding scratches or misprocessing during the shifting process.

[0048] (III) Roll forming control of each reinforcing rib After the barrel is moved to the current preset processing position, the control system first controls the adjustment component to lower the mounting platform 18, so that the first rolling wheel 6, the second rolling wheel 7, and the main rolling wheel 8 above contact the surface of the barrel and reach the set rolling pressure. Then, the control system starts the motor 4, and the drive shaft 5 drives the first rolling wheel 6, the second rolling wheel 7, and the main rolling wheel 8 below to rotate, thereby squeezing and rubbing the barrel wall, so that the barrel rotates around its own axis under the limit of the clamping component, completing the rolling forming of a circumferential reinforcing rib. During the rolling process, the control system monitors the clamping status of the barrel in real time through the pressure sensor 27 and maintains the clamping force stable according to the aforementioned compensation logic.

[0049] (iv) Judgment of multi-rib loop and processing completion After completing the rolling of one reinforcing rib, the control system automatically determines whether the current number of processed ribs is equal to the preset number of ribs. If the preset number of ribs is not reached, the process of "lifting the first rolling wheel 6 / second rolling wheel 7 / main rolling wheel 8 - shifting the barrel - lowering the first rolling wheel 6 / second rolling wheel 7 / main rolling wheel 8 - forming the ribs" is repeated until all reinforcing ribs are processed. When the last reinforcing rib is rolled, the control system automatically resets the first rolling wheel 6 / second rolling wheel 7 / main rolling wheel 8 to the initial height and moves the drive assembly to the initial position. At the same time, an audio-visual prompt is issued through the operation panel 3 to notify the operator that the processing is complete.

[0050] (v) Safety interlocks and abnormal handling In automatic cycle processing mode, the control system continuously monitors the operating status of each actuator. If motor overload, abnormal signal of pressure sensor 27, or timeout of electric telescopic rod 28 occurs, the control system immediately interrupts automatic cycle, stops all moving parts, and displays fault information on the operation panel 3. Operation can only be resumed after the fault is manually rectified. In addition, the operation panel 3 is equipped with an emergency stop button and a mode switching switch, so that the operator can interrupt automatic cycle at any time and switch to manual mode for debugging or troubleshooting.

[0051] The overall workflow of this invention is as follows: After placing the barrel on the processing platform 2, the equipment is started via the operation panel 3. The control system first controls the clamping assembly to clamp the barrel and insert both ends of the barrel into the positioning slots 26 of the clamping block 25. The pressure sensor 27 detects the preset pressure value. Subsequently, the adjustment assembly automatically adjusts the height of the mounting platform 18 according to the diameter of the barrel to align the rib rolling assembly. The drive assembly moves the barrel to the processing position of the first reinforcing rib. The motor 4 starts, and the drive shaft 5 drives the lower first rib rolling wheel 6, second rib rolling wheel 7, and main rib rolling wheel 8 to rotate, cooperating with the upper first rib rolling wheel 6, second rib rolling wheel 7, and main rib rolling wheel 8 to complete the rolling of one reinforcing rib. During the processing, if the axial shortening of the barrel causes the pressure sensor 27 to detect a value lower than the preset threshold, the control system immediately triggers the electric telescopic rod 28 to drive the clamping plate 29 to compensate and clamp. After the processing of one rib is completed, the drive assembly moves the barrel to the next processing position. The above process is repeated until all reinforcing ribs are processed. After processing is completed, the clamping assembly and the compensation assembly are reset, and the operator removes the barrel.
