[0030] The working principle and usage process of the present utility model: When this device is actually used:

[0031] When the device is working, the material moving structure 8 of the device sucks the material firmly through the vacuum adsorption end at the bottom, and with the assistance of the rolling of multiple balls on the top of the material auxiliary moving platform 5, moves the material to the material clamping position of the device. At this time, the servo motor 14 can be controlled to work through the control panel 6, driving the screw rod lifting structure, so that the material limiting clamp 10 presses down, fixing the side of the material to be processed on the fixed seat 12 of the device. At this time, according to the pre-entered processing information, the control panel 6 will control the driving motor 18 to work, providing power for the operation of the bending structure, so that the bending main knife 19 performs sheet metal bending operation on the side of the material;

[0032] When the processing requirement of the material requires separate bending of a specific position on a specific side, at this time, the second electric slider 21 on the bending main knife 19 can be controlled through the control panel 6. After receiving the control information, the servo drive motor in the second electric slider 21 will work, converting the rotation of the motor into the linear sliding of the second electric slider 21 on the second electric slide rail 22 through the screw drive structure in the second electric slider 21, so that the second electric slider 21 drives the bending sub-knife 24 to move and adjust to the processing position under the electric control. At this time, the control panel 6 controls the hydraulic cylinder 18 to work, enabling the bending structure to work. At this time, the protruding distance of the bending sub-knife 24 covers the protruding distance of the bending main knife 19. At this time, the bending sub-knife 24 that has been moved and adjusted to the processing position participates in the bending action, enabling the bending sub-knife 24 to perform separate sheet metal bending on the specific segmented edge position of the edge segmented metal sheet;

[0033] The overall design enables the device to not only meet the conditions of normal sheet metal bending but also perform separate sheet metal processing on the specific segmented positions of specific edge segmented plates, effectively improving the processing range of the device.
