[0002] PVC is a material mainly composed of polyvinyl chloride, with other components added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back coating adhesive; PVC pipes are rigid polyvinyl chloride pipes, which are extruded by hot pressing after being compounded with polyvinyl chloride resin, stabilizers, lubricants, etc. They are the earliest plastic pipes to be developed and applied. PVC pipes are divided into PVC-U pipes, PVC-M pipes and PVC-O pipes.
[0003] However, when the existing pipe bending device for PVC pipes is in use, the PVC pipes are usually bent by a bending device. However, the bending device is fixed to the operating table by bolts. When bending the PVC pipes, the staff needs to manually adjust the position of the PVC pipes many times. The operation steps are cumbersome and the workload is large. At the same time, when the PVC pipes are bent, the PVC pipes will shift under the influence of external forces, which will affect the bending efficiency of the PVC pipes to a certain extent. Therefore, a pipe bending device for PVC pipes is provided. Summary of the Utility Model
