In order to adapt to the production of cabinet panels of different sizes (such as width, depth, and edge folding), flexible roll forming technology has become the key to improving production capacity.

[0003] Patent CN117381384A discloses a quick-change device for a straightening roller system, including an upper frame assembly, a lower base assembly, and a frame. The lower base assembly is mounted on the frame, and the upper frame assembly is mounted on the upper part of the lower base assembly. Three sets of rails are installed on the upper frame assembly, and a wheel is movably connected to each set of rails.

[0016] Step 1: System initialization and status self-check; After the integrated electrical control center is started, it reads the absolute coordinates of each servo axis and the sensor group scans the status of the hydraulic, pneumatic and lubrication systems to confirm that the system meets the roll change trigger conditions;

[0017] Step 2: Production task analysis and roll change instruction issuance; Input the production specification code through the human-machine interface, the integrated electrical control center calls the roll mold configuration scheme from the database, calculates the difference between the online roll mold group and the target roll mold group, and sends the scheduling instruction to the automatic roll change shuttle mechanism.

The roll gap can be automatically adjusted within a certain range by the electrical control system, enabling the same set of rollers to be compatible with different sheet materials of a certain thickness without replacing any parts.

The drive motor is equipped with an electromagnetic brake mechanism, which can immediately lock the position in the event of a power outage or other emergency to prevent slippage. The alignment robot 505 adopts a dual redundancy design of hydraulic clamping and pin positioning. After the positioning pin at the end of the alignment robot 505 is inserted into the positioning hole on the upright, a micro-tensioning mechanism inside the pin shaft is driven by a hydraulic cylinder to achieve a gapless rigid connection between the alignment robot 505 and the square platform 4032. This design effectively counteracts dynamic vibrations during movement and ensures the spatial posture stability of the heavy-duty upright during high-speed transport.

[0044] In this embodiment: Automatic rapid roll changing method: Step 1: System initialization and status self-check; After the integrated electrical control center 101 is started, it reads the absolute coordinates of each servo axis and the sensor group scans the status of the hydraulic, air pressure and lubrication system to confirm that the system meets the roll changing trigger conditions;

[0045] Step 2: Production task analysis and roll change instruction issuance; Input the production specification code through the human-machine interface, the integrated electrical control center 101 calls the roll mold configuration scheme from the database, calculates the difference between the online roll mold group and the target roll mold group, and sends a scheduling instruction to the automatic roll change shuttle mechanism 5. The online roll mold group includes: multi-level distribution transmission box 409, fitting assembly 412, electromagnetic upper limit platform 4031 and electromagnetic lower limit platform 4041, second rectangular frame 403 and square platform 4032. The target roll mold group includes the external multi-station storage rack to retrieve the new forming stand module.

[0046] Step 3: Automatic separation of the online roller module; the multi-stage distribution transmission box 409 stops power output, starts the fitting assembly 412 to release pressure, causing the internal expansion fitting assembly to unfold and disconnect the power connection; at the same time, the electromagnetic upper limit platform 4031 and the electromagnetic lower limit platform 4041 separate and release each other, releasing the rigid constraint between the second rectangular frame 403 and the square platform 4032.

[0047] Step 4: Extraction and transfer of the roller module; The automatic roller changing shuttle mechanism 5 moves to the target station, the alignment component locks and grabs the rectangular groove under the square platform 4032, and transfers the stand to the empty compartment of the external multi-station storage rack set on one side of the multi-specification metal cabinet panel flexible roll forming machine.

[0048] Step 5: Retrieval and positioning of the target roller module; The automatic roller changing shuttle mechanism 5 retrieves the new forming stand module from the external multi-station storage rack and places it on the second rectangular frame 403;

[0049] Step 6: Precision coupling and rigid locking; Align the flexible rolling mechanism 4 with the horizontal and vertical positions of the alignment components, and simultaneously open the electromagnetic upper limit stage 4031 and the electromagnetic lower limit stage 4041 to lock the flexible rolling mechanism 4.

[0050] Step 7: Automatic machine adjustment and size calibration; The absolute value servo motor drives the third lead screw assembly 405 to adjust the distance between the left and right second uprights 406, and the vertical adjustment first power motor 407 drives the fourth lead screw 4061 to rotate and move the forming roller shaft 413. The laser range sensor 410 completes the forming roller gap calibration. The active end of the forming roller shaft 413 is placed in the fitting assembly 412 to make the expansion fitting assembly mesh. The driven end positioning spline 416 completes the power coupling.

[0051] Step 8: Trial Operation; The system conducts a low-speed linkage test, and the operating parameters are monitored in real time through the sensor group. After confirming that there are no errors, it enters the production waiting state.

[0052] It also includes an adaptive adjustment process for strip thickness fluctuations: when the metal panel passes through the guide plate 301, the strip thickness data is collected in real time by the collector and transmitted to the integrated electrical control center 101. The integrated electrical control center 101 finely adjusts the set value of the roll gap for each pass in real time according to the material thickness tolerance. At the same time, during the operation of step eight, the integrated electrical control center 101 monitors the reverse load through the stress sensor installed inside the flexible roll forming machine for multi-specification metal cabinet panels.

[0053] Working Principle: During operation, the integrated electrical control center 101, initial pressure roller mechanism 2, guiding mechanism 3, flexible rolling mechanism 4, and automatic roller changing shuttle mechanism 5 are centrally located to roll-form the metal cabinet panel. After forming, the forming rollers can be flexibly changed according to the width of the metal cabinet panel. After the integrated electrical control center 101 is started, it reads the absolute coordinates of each servo axis and the sensor group scans the status of the hydraulic, pneumatic, and lubrication systems to confirm that the system meets the roller changing trigger conditions. The production specification code is then input through the human-machine interface. The integrated electrical control center 101 retrieves the roller mold configuration scheme from the database, calculates the difference between the online roller mold group and the target roller mold group, and sends a scheduling command to the automatic roller changing shuttle mechanism 5. The multi-level distribution transmission box 409 stops power output, and the locking assembly 412 is activated to release pressure, causing the internal expansion locking assembly to unfold and disconnect the power connection. At the same time, the electromagnetic upper limit platform 4031 and the electromagnetic lower limit platform 4041 separate and release from each other, releasing the rigid constraint between the second rectangular frame 403 and the square platform 4032. The automatic roller changing shuttle mechanism 5 moves to the target station and aligns. The component locks and grasps the rectangular groove below the square platform 4032, transferring the upright to an empty slot in the external multi-station storage rack located on one side of the multi-specification metal cabinet panel flexible roll forming machine. The automatic roll changing shuttle mechanism 5 retrieves a new forming upright module from the external multi-station storage rack and places it on the second rectangular frame 403, precisely coupling and rigidly locking it. The alignment component adjusts the horizontal and vertical positions of the flexible roll forming mechanism 4 to align, and simultaneously activates the electromagnetic upper limit platform 4031 and electromagnetic lower limit platform 4041 to lock the flexible roll forming mechanism 4, ensuring... The servo motor drives the third lead screw assembly 405 to adjust the distance between the left and right second uprights 406. The vertical adjustment first power motor 407 drives the fourth lead screw 4061 to rotate, which in turn moves the forming roller shaft 413. The laser range sensor 410 completes the calibration of the forming roller gap. The active end of the forming roller shaft 413 is placed in the fitting assembly 412 to make the expansion fitting assembly mesh. The driven end is positioned by the spline 416 to complete the power coupling. The system performs a low-speed linkage test and monitors the operating parameters in real time through the sensor group. After confirming that there are no errors, it enters the material waiting production state.
