[0040] Working principle of the present invention:

[0041] 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-bar 35 in the positioning device 3 can be disassembled to achieve the sliding adjustment of the hydraulic cylinder telescopic devices 2 along the length direction of the processing platform 1 to meet the support limit requirements at both ends of the workpiece;

[0042] 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.

[0043] 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 limiting clamp ring 261, so that the two ends of the workpiece are limitedly installed in the limiting clamp ring 261. When the two ends of the workpiece are placed, the limiting handle 262 is pulled to release the limiting handle 262 from limiting the open mouth of the limiting clamp ring 261. After the workpiece is placed, the limiting handle 262 is released so that the workpiece is always limited in the limiting clamp ring 261.

[0044] 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 one limiting snap ring 261 respectively, so that the four workpieces are limited on the hydraulic cylinder telescopic device 2 and the positioning device 3;

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, a plurality of workpieces are welded by using a rectangular ring to realize the 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 applied to the sizes of different workpieces and the sizes of different arch frame processing.

[0046] 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 thereon 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.
