The steps are clear and the bending effect is accurate and reliable.

[0091] The working principle of this embodiment is as follows: the staff only needs to put the PVC pipe into the storage structure 3, and the PVC pipe enters the groove between the fixed tooth plates 58 through the feed port 56.

The connecting column 32 stops when it reaches the limit sleeve at one end, and the threaded rod 33 moves and drives the double-headed toothed tube 47 to mesh with the other first toothed tube 43. The third bevel gear 45 structure drives the threaded rod 33 to rotate in the opposite direction. In this way, large-scale bending operations can be carried out in a cycle, which greatly improves production efficiency. After the bending is completed, the slide plate 19 cooperates with the inclined groove 20 and the L-shaped groove 17 to make the center column 10 move along the L-shaped groove 17, and in this process, the center column 10 pushes the PVC pipe to fall off the first spring 15, and slides out through the discharge slide 66, and the operation is completed. This design greatly improves the automation level and production efficiency of the PVC pipe bending operation.
