[0032] Furthermore, the first clamping mechanism 2 includes a first fixed plate 21 fixedly installed on the machine base 4 perpendicular to the length direction of the machine base 4. The first fixed plate 21 has a movable pushable first top plate 23 on one end located inside the machine base 4, and a first clamping cylinder 22 is provided at the other end of the first fixed plate 21. The output end of the first clamping cylinder 22 is driven and connected to the first top plate 23.

[0033] Furthermore, the first limiting mechanism 3 includes a first support plate 32 fixedly installed on the machine base 4. The first support plate 32 is disposed opposite to the first top plate 23, and the end face of the first support plate 32 is parallel to the end face of the first top plate 23.

[0034] A bending plate 31 is connected to one end of the first support plate 32 relative to the bending mechanism 1. The bending plate 31 can rotate freely around the connection end between the first support plate 32 and the bending plate 31.

[0035] Furthermore, the bending plate 31 can rotate freely around the first support plate 32 and the connecting end of the bending plate 31 by an angle of 0°-180°.

[0036] Furthermore, the feeding mechanism 6 includes a base plate 63 that is slidably connected to the machine base 4. A drive motor 61 is provided on the base plate 63. The drive motor 61 passes through the base plate 63 and is connected to a drive gear 62. The machine base 4 is provided with a long rack 5 along its length that meshes with the drive gear 62 for transmission.

[0037] Furthermore, the second clamping mechanism 8 includes a second fixed plate 81 fixedly installed on the base plate 63. The second fixed plate 81 has a second top plate 83 that can be moved and pushed on one end of the second fixed plate 81 located inside the machine base 4. The rear end of the second fixed plate 81 is provided with a second clamping cylinder 82. The output end of the second clamping cylinder 82 is driven and connected to the second top plate 83.

[0038] Furthermore, the second limiting mechanism 9 includes a second support plate 91 disposed relative to the second top plate 83, with one bottom end of the second support plate 91 fixedly connected to the bottom plate 63.

[0039] Furthermore, a drag chain 7 is connected between the machine base 4 and the feeding mechanism 6, and the drag chain 7 is equipped with a control line for connecting the drive motor 61 and the machine base 4.

[0040] The working principle of the automatic bending machine based on Embodiment 1 is as follows: First, the workpiece to be bent is placed on the machine base 4. The first end of the workpiece is placed between the first clamping mechanism 2 and the first limiting mechanism 3. The second end of the workpiece is clamped by the second clamping mechanism 8 and the second limiting mechanism 9. The second clamping mechanism 8 drives the second top plate 83 to move through the second clamping cylinder 82, so that the second top plate 83 cooperates with the second support plate 91 to fix the end of the workpiece. At this time, the feeding mechanism 6 is in the initial position away from the bending mechanism 1, and the drive motor 61 is started. The drive gear 62 meshes with the long rack 5 on the machine base 4, driving the base plate 63 to move the second clamping mechanism 8, the second limiting mechanism 9, and the fixed workpiece along the length of the machine base 4 toward the bending mechanism 1, pushing the workpiece toward the bending mechanism 1. After the workpiece is pushed into place, the front end of the workpiece extends outward through the bending mechanism 1. The bending cylinder 11 is activated, driving the push plate 12 to move. The push plate 12 pushes the side wall of the workpiece along one side of the bending plate 31, causing the bending plate 31 to rotate under force. After rotating to its limit position, the 31 stops rotating, providing support. The push plate 12 continues to push the workpiece, causing the pushed end of the workpiece to form an angle with the end fixed to the first clamping mechanism 2 and the first limiting mechanism 3, thus completing the bending operation. The first clamping mechanism 2 drives the first top plate 23 to move through the first clamping cylinder 22, causing the first top plate 23 to move towards the first support plate 32 of the first limiting mechanism 3. It cooperates with the first support plate 32 to clamp the end of the workpiece adjacent to the bending end, preventing the non-bent end of the workpiece from undergoing unnecessary deformation due to bending stress. After bending is completed, the first clamping mechanism 2 and the second clamping mechanism 8 are released, the bent workpiece is taken out, and the drive motor 61 is driven in reverse to return the feed mechanism 6 to its initial position for the next round of bending operation. Since the machine base 4 and the feed mechanism 6 are connected by a drag chain 7, the control line in the drag chain 7 is used to connect the drive motor 61 and the machine base 4, so that the drive motor 61 can still receive and control signals normally during the movement, thereby accurately controlling the feed amount of the workpiece.

[0041] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
