When the material passes through the expansion mold (9) and the arc-shaped limit mold (10), the material can be limited and formed, and an integrated curved pipe can be quickly generated. Compared with the traditional spliced ​​curved pipe, it is more practical and firm, thereby improving the working efficiency of the forming device; S3. When the conveying screw (16) is used for a long time or the device needs to be regularly maintained, the conveying screw (16) can be quickly disassembled and replaced or maintained by disassembling the maintenance component (6), and the heating conveying pipe (7) can also be flushed, thereby improving the practicality of the device.
