After the workpiece is placed in the limit clamping ring 261, the limit handle 262 is released. The limit handle 262 is reset under the action of the potential energy of the spring 263, so that the two ends of the limit handle 262 are respectively located in the limit clamping plates 26 on both sides of the limit clamping ring 261, thereby limiting the workpiece in the limit clamping ring 261.

[0035] Preferably, in this embodiment, four limiting clamps 261 are provided, and the four limiting clamps 261 are distributed in groups of two up and down on the limiting clamping plate 26, and a workpiece is placed in each clamp. When each workpiece reaches the bending size, a rectangular fixing ring can be inserted into the workpiece and welded to each workpiece to fix the position of each workpiece to form an integrated structure between multiple workpieces, thereby reducing the matching and fixing during welding between workpieces, simplifying the operation process, and improving processing efficiency.

[0036] In this embodiment, a positioning plate 34 is provided at one end of the positioning slot 33, and the positioning plate 34 is fixedly connected to the processing platform 1.

[0038] In another embodiment, a limiting arc groove 321 is provided on the positioning fixture 32, and the limiting arc groove 321 runs through the positioning fixture 32. In this embodiment, when the workpiece is not limited and fixed, there is a possibility of middle slippage. By providing the limiting arc groove 321 on the positioning block 31, the limiting arc groove 321 improves the limiting stability of the workpiece.

[0039] In this embodiment, the transmission device 4 includes a drive motor 42 and a transmission rod 41. The transmission rod 41 is located between the processing platform 1 and the track beam 11, and its two ends are rotatably connected to the vertical plate 12 through a mounting seat. The fixed end of the drive motor 42 is fixedly connected to the track beam 11, and its output end is transmission-connected to the transmission rod 41. The drive motor 42 drives the two hydraulic cylinder telescopic devices 2 to slide on the track beam 11, so that the positions of the two hydraulic cylinder telescopic devices 2 change with each other to adapt to the different lengths of the processed workpieces.

[0040] Advantageously, the transmission rod 41 is provided with a first thread 411 and a second thread 412, and the first thread 411 and the second thread 412 are respectively located at the two ends of the transmission rod 41 and have opposite spiral directions. The first thread 411 and the second thread 412 are respectively threadedly engaged with one of the threaded holes 221, and the first thread 411 and the second thread 412 have the same pitch and opposite spiral directions. When the motor drives the transmission rod 41 to rotate, the positions of the two hydraulic cylinder telescopic devices 2 are brought closer to or away from each other, thereby realizing the adjustment of the position of the hydraulic cylinder telescopic device 2 and realizing the support and limit fixation of the two ends of workpieces of different lengths.

[0041] Working principle of the present invention:

[0042] The positions of the two hydraulic cylinder telescopic devices 2 on the processing platform 1 are adjusted according to the actual length of the workpiece. At the same time, in order to meet the adjustment requirements of the hydraulic cylinder telescopic devices 2, the positioning T-rod 35 in the positioning device 3 can be disassembled to achieve sliding adjustment of the hydraulic cylinder telescopic devices 2 along the length direction of the processing platform 1 to meet the support and limit requirements at both ends of the workpiece;

[0043] The driving motor 42 is started to drive the transmission rod 41 to rotate between the two vertical plates 12. The first thread 411 and the second thread 412 at both ends of the transmission rod 41 correspond to a hydraulic cylinder telescopic device 2 respectively, wherein the spiral directions of the first thread 411 and the second thread 412 are opposite. A threaded hole 221 is provided on the cylinder platform 22, and the threads are respectively threadedly connected with the threads provided on the transmission rod 41. The cylinder platform 22 is fixedly connected to the slider 21, and the slider 21 slides on the track beam 11. The driving motor 42 drives the transmission rod 41 to rotate to realize the two hydraulic cylinder telescopic devices 2 to move closer to or away from each other, thereby realizing the support and limitation of the hydraulic cylinder telescopic device 2 on workpieces of different lengths;

[0044] After adjusting the position of each positioning device 3 in the corresponding positioning slot 33 and adjusting the relative positions of the hydraulic cylinder telescopic device 2 and the positioning device 3, the workpiece is placed on the hydraulic cylinder telescopic device 2 and the positioning device 3 respectively, wherein the two ends of the workpiece are respectively placed in the limit clamping ring 261 so that the two ends of the workpiece are limitedly installed in the limit clamping ring 261. When the two ends of the workpiece are placed, the limit handle 262 is pulled to release the limit handle 262 from the open mouth of the limit clamping ring 261. After the workpiece is placed, the limit handle 262 is released so that the workpiece is always limited in the limit clamping ring 261.

[0045] In the positioning device 3, according to the actual bending size, each positioning block 31 is adjusted in turn in the corresponding positioning slot 33, and the workpiece is located between the vertical angle formed by the positioning fixture 32 and the upper end surface of the positioning block 31, and the positioning T rod 35 in each positioning device 3 is rotated in turn, and the positioning T rod 35 is threadedly matched with the corresponding positioning plate 34 to realize the sliding of the positioning block 31 in the corresponding positioning slot 33. By changing the relative position of each positioning device 3, the curvature of the workpiece is changed, and the limiting and fixing of the workpiece are realized at the same time. Among them, there are four limiting snap rings 261 in the hydraulic cylinder telescopic device 2, and the four positioning fixtures 32 in the positioning device 3 correspond to a limiting snap ring 261 respectively, so that the four workpieces are limited to the hydraulic cylinder telescopic device 2 and the positioning device 3;

[0046] When the hydraulic cylinder telescopic device 2 limits the workpiece, by starting the hydraulic cylinder 23, the output end of the hydraulic cylinder 23 drives the fixed clamp 24 to slide in the clamp slide 251 formed in the telescopic plate 25, so that the hydraulic cylinder 23 drives the limit clamp 26 to change its position, so that one end of the workpiece placed in the limit clamp ring 261 changes. Through the coordination between the hydraulic cylinder telescopic device 2 and the positioning device 3, different height differences are formed between each adjacent hydraulic cylinder telescopic device 2 and the positioning device 3 in the width direction of the processing platform 1, so as to realize the bending and support limitation of the workpiece and the fixation of the workpiece. After the workpiece is bent and fixed, the multiple workpieces are welded by using rectangular rings to realize welding between the workpieces, which simplifies the need to fix and weld the workpiece after bending the workpiece in the prior art. The equipment realizes the bending of the workpiece and the welding after bending through the coordination between the hydraulic cylinder telescopic device 2 and the positioning device 3. The adjustable position of the hydraulic cylinder telescopic device 2 and the positioning device 3 on the processing platform 1 can be adapted to the sizes of different workpieces and the requirements of different arch processing sizes.

[0047] In another embodiment, in order to improve the stability of the positioning fixture 32 in limiting the workpiece, a limiting arc groove 321 is opened on it so that the workpiece is limited in the limiting arc groove 321. The limiting stability of the workpiece in this embodiment is better than that in the previous embodiment.
