Description

Technical Field

[0001] The utility model relates to the technical field of pipeline expanding equipment, in particular to a plastic pipe expanding equipment with a clamping and positioning mechanism. Background Art

[0002] Plastic pipe expansion equipment is a mechanical device used to increase the diameter of the plastic pipe head, that is, to expand the plastic pipe to meet different connection requirements. Generally, the expansion mold is heated at high temperature to soften the plastic pipe head, and then the mold is used to apply pressure to the pipe to gradually expand it into the required specifications and shape.

[0003] For example, the application has a publication number of CN219789267U, in which a displacement adjustment mechanism of a clamping device is provided, which can facilitate clamping and fixing of plastic pipes of different lengths, and can also perform expansion work on plastic pipes of different lengths, so as to improve the practicability of the device, and clamp and fix one end of the plastic pipe by a clamping plate, and then insert the conical column at the other end into the interior of the plastic pipe, so as to expand the pipe mouth of the plastic pipe. However, when expanding the pipe, this application cannot achieve continuous automatic expansion and cannot improve the expansion efficiency of the pipe. At the same time, the center points of pipes of different diameters are at different positions. Therefore, when expanding pipes of different diameters, the center point of the conical column and the center point of the pipe cannot be in the same axial position, and thus can only expand pipes of a single diameter, making the entire device less applicable.
