A motor 502 is fixedly installed on one of the baffles 501. The output shaft of the motor 502 is axially fixedly connected to the bidirectional lead screw 503, which can adjust the distance between the mounting base 52 and the vertical plate 53. At the same time, it can adjust the distance between the mounting base 52 and the vertical plate 53 and the operating table 2, so as to facilitate the use of the bending die 54 or the cutting blade 521 to process the sheet metal. Two fixing blocks are fixedly installed on one side of the vertical plate 53. The same adjusting screw 531, which is threadedly connected to the lifting seat 541, is rotatably installed on the two fixing blocks. A motor 532 is fixedly installed on one of the fixing blocks. The output shaft of the motor 532 is axially fixedly connected to the adjusting screw 531. The initial distance between the bending die 54 and the operating table 2 can be adjusted according to the size of the sheet metal to be processed. This can reduce the extension length of the electric cylinder 51 during bending operations, thereby improving the working efficiency of bending operations to a certain extent. The control panel 6 is located on one side of the housing 1 and above the rectangular opening. In order to provide effective support for the control panel 6 and to facilitate the operator to adjust the orientation and tilt angle according to actual needs, a hinge seat 61 is hinged to the control panel 6 via a damping hinge. A damping shaft is fixedly installed on the bottom side of the hinge seat 61. A support plate 62 is fixedly installed on one side of the housing 1. The support plate 62 is located above the rectangular opening and is connected to the damping shaft for damping rotation.

[0027] In this embodiment, two arc-shaped support blocks 401 are fixedly installed on the L-shaped plate 4 based on the rotating pin as the center. Both support blocks 401 are in sliding contact with the side wall of the box 1, which can ensure that the L-shaped plate 4 maintains stable rotation based on the support pin 41 as the center, and at the same time ensure the working stability of the L-shaped plate 4 during the operation of the device.

[0028] To improve the accuracy of the adjustment and ensure the stability after the adjustment is completed, servo motors are used for motors 1, 2, 3 and 4.

[0029] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0030] Working principle: When in use, first turn on the power, place the sheet metal to be processed on the operating table 2, start the electric cylinder 23, the electric cylinder 23 drives the slide 22 to move laterally within the rectangular opening to achieve precise feeding. Then, start the electric cylinder 3, the electric cylinder 3 pushes the mounting plate 31 to move along the guide rod 303, so that the positioning seat 33 descends to contact the sheet metal, which can clamp and position the sheet metal. At the same time, the pressure sensor 34 monitors the clamping force of the positioning seat 33 on the sheet metal in real time. The slider 341 slides in the slide groove. The position of the pressure sensor 34 is adaptively adjusted by the spring 342 to ensure that the clamping force is stable and does not affect the clamping operation. At the same time, it can monitor the clamping force in real time to avoid over-clamping or insufficient clamping force.

[0031] Then, the bidirectional lead screw 503 is rotated by motor 3 502, thereby adjusting the bending die 54 on the vertical plate 53 to the position corresponding to the plate on the operating table 2. Then, the lifting plate 5 is moved by electric cylinder 3 51 to perform the bending operation. When the plate thickness is small, the position of the lifting seat 541 can be adjusted by motor 4 532 to adjust the lead screw 531 so that its initial position is close to the plate on the operating table 2. Then, the lifting plate 5 is moved by electric cylinder 3 51 to control the bending die 54 to perform the bending operation. This can effectively reduce the extension stroke of electric cylinder 3 51 during the bending operation, thereby improving the bending efficiency to a certain extent.

[0032] When it is necessary to call the bending die 54 or the cutting cutter 521, start the motor 3 502. The motor 3 502 drives the bidirectional lead screw 503 to rotate in the opposite direction, adjusting the distance between the mounting base 52 and the vertical plate 53, as well as the distance between them and the operating table 2. This allows the cutting cutter 521 to be adjusted to a suitable position for cutting. Then, the electric cylinder 3 51 controls the lifting plate 5 to move closer to the operating table 2 and cooperates with the operating table 2 and the positioning seat 33 to perform the cutting operation.

[0033] When bending operations are required on the front and rear sides of the sheet metal, the mounting plate 31 is first moved upward by the electric cylinder 3. Then, the support column 32 is driven to rotate by the motor 311 in conjunction with the gear 312 and the gear 313. At the same time, the motor 43 drives the drive gear 44 to rotate. The drive gear 44 meshes with the transmission gear 42, causing the L-shaped plate 4 to rotate around the support pin 41, thereby adjusting the orientation of the bending die 54. This allows the positioning seat 33 to be adjusted to the position corresponding to the bending die 54. Then, the bending die 54 is controlled to perform the bending operation. Because the orientation of the positioning seat 33 and the bending die 54 can be flexibly adjusted, it can well adapt to bending requirements in different directions.

[0034] After the bending process is completed, the electric cylinder 23 is restarted to control the horizontal movement of the operating table 2 to realize the material discharge operation. The operator can flexibly adjust the orientation and tilt angle of the control panel 6 through the damping hinge and damping shaft according to the actual operating scenario, so as to operate and monitor the entire processing process more conveniently. During the operation of the entire device, the support block 401 on the L-shaped plate 4 slides in contact with the side wall of the box 1 to ensure the stability of the rotation and operation of the L-shaped plate 4. All components work together to efficiently and accurately complete the bending and forming processing tasks of complex-shaped sheet metal.

[0035] The foregoing has provided a detailed description of a bending and forming apparatus suitable for complex-shaped sheet metal. Specific embodiments have been used to illustrate the principles and implementation methods of the invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concepts of the invention. It should be noted that those skilled in the art can make various improvements and modifications to the invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
