When it is necessary to process the plate, the second slider 43 moves along the second slide rail 42, so that the plate conveying mechanism 4 is located outside the bracket 11, so that it is convenient to process the plate.

[0049] At the same time, in order to prevent the lower connecting plate 44 from moving arbitrarily and to ensure that the lower connecting plate 44 can be stably located in a required position, a first limiting groove 412 is provided in the middle position of the second supporting plate 41, and the first limiting groove 412 is provided between the two second slide rails 42, and the first limiting groove 412 is arranged parallel to the second slide rail 42, and a first connecting column 413 of the first locking handle 411 is slidably connected in the first limiting groove 412, and one end of the first connecting column 413 of the first locking handle 411 passes through the lower connecting plate 44, so that the handle end of the first locking handle 411 is located in the lower connecting plate On the top surface of the plate 44, the first connecting column 413 of the first locking handle 411 passes through one end of the first limiting groove 412 and is fixedly connected to the first limiting block 414.

When the first limiting block 414 is separated from the bottom surface of the second support plate 41, the second slider 43 can move along the second slide rail 42; when the first limiting block 414 is tightly abutted against the bottom surface of the second support plate 41, the second slider 43 cannot move along the second slide rail 42.

The third slider 54 moves along the third slide rail 53, so that the fourth support plate 55 can move along the third slide rail 53.

[0052] At the same time, in order to prevent the fourth support plate 55 from moving arbitrarily and to ensure that the fourth support plate 55 can be stably located in the required position, a third limiting groove 513 is provided on the top surface of the third support plate 52, and a second connecting column of the second locking handle 511 is slidably connected in the third limiting groove 513, and the third limiting groove 513 is provided between the two third slide rails 53, and the third limiting groove 513 is arranged parallel to the third slide rail 53, and a sixth limiting groove 516 is provided on the bottom surface of the third support plate 52, and the third limiting groove 513 is connected to the sixth limiting groove 516, and the width of the sixth limiting groove 516 is greater than the width of the third limiting groove 513, that is, the third limiting groove 5 The width of 13 is adapted to the second connecting column of the second locking handle 511, and the width of the sixth limiting groove 516 is adapted to the second limiting block of the second locking handle 511. By rotating or moving the handle of the second locking handle 511 up and down, the second limiting block of the second locking handle 511 is separated from or tightly abutted against the third limiting groove 513. When the second limiting block of the second locking handle 511 is separated from the third limiting groove 513, the third slider 54 can move along the third slide rail 53; when the second limiting block of the second locking handle 511 is tightly abutted against the third limiting groove 513, the third slider 54 cannot move along the third slide rail 53.

[0053] The structure of the second locking handle 511 is the same as that of the first locking handle 411 .

After the pipe passes through the hollow tube 62, the electric clamp 61 clamps the pipe, so that the electric clamp 61 can drive the pipe to move along the electric guide rail 51.

[0057] In order to facilitate the rotation of the pipe, an electric turntable is fixedly connected to the end of the cylinder away from the electric clamp 61, and the end of the electric turntable away from the cylinder is fixedly connected to the support plate. The electric turntable is driven by a stepper motor so that the electric turntable can rotate at different angles as needed.

[0058] Working process:

[0059] When it is necessary to bend the pipe, first control the cutting mechanism 3 and the plate conveying mechanism 4 to retract so that the cutting mechanism 3 and the plate conveying mechanism 4 are not on the pipe conveying route; then, according to the specifications of the pipe, the matching active roller 23 and the driven roller 24 are installed on the bending machine 22, and then one end of the pipe is passed through the pipe conveying mechanism 5, and the pipe is extended between the active roller 23 and the driven roller 24, and then, the pipe is clamped by the clamping assembly 6 of the pipe conveying mechanism 5. By setting the parameters, the pipe conveying mechanism 5 pushes the pipe along the electric guide rail 51, or angles the pipe as required. The rotation of the bending mechanism 2 and the pipe conveying mechanism 5 enables the bending mechanism 2 and the pipe conveying mechanism 5 to work according to the parameters. After the pipe is bent, it is cut by the cutting mechanism 3 to complete the bending of the pipe. When the distance between the pipe conveying mechanism 5 and the bending mechanism 2 reaches a predetermined distance, the clamping assembly 6 releases the pipe, and the pipe conveying mechanism 5 retreats along the electric guide rail 51. Since the pipe is between the active roller 23 and the driven roller 24, the pipe will not move with the pipe conveying mechanism 5. After the pipe conveying mechanism 5 retreats to the starting position, the clamping assembly 6 clamps the pipe again to continue bending the pipe.

[0060] When it is necessary to bend the plate, first control the cutting mechanism 3 and the pipe conveying mechanism 5 to retract so that the cutting mechanism 3 and the pipe conveying mechanism 5 are not on the plate conveying route; then the plate conveying mechanism 4 extends from the bracket 11, and the plate conveying mechanism 4 is aligned with the bending mechanism 2, and then the plate is placed on the plate conveying mechanism 4. The plate conveying mechanism 4 can be adjusted according to the thickness of the plate, so that the plate conveying mechanism 4 can clamp and convey the plate. Through the setting of parameters, the plate conveying mechanism 4 pushes the plate as required, so that the bending mechanism 2 can bend the plate according to the parameters. After the plate is bent, it is cut by the cutting mechanism 3, and the bending of the plate is completed.
