The plastic pipeline inner layer enters the tractor after being extruded by the extruder, then enters the winding machine after being drawn by the tractor to be wound and coated with the reinforcing belt, a certain extrusion force can be generated on the plastic pipeline inner layer by the reinforcing layer in the winding process, the temperature of the plastic pipeline inner layer extruded by the extruder is higher at the moment, the plastic pipeline inner layer can deform by the extrusion force of the reinforcing layer, in order to prevent the phenomenon, a core rod is usually arranged in the tractor, enters the plastic pipeline inner layer and enters the winding machine along with the plastic pipeline inner layer, and the plastic pipeline inner layer can be prevented from deforming when the reinforcing belt is wound under the supporting action of the core rod.
However, the existing core rod is a solid metal rod, which has high strength and can well support the inner layer of the plastic pipeline, and meanwhile, the technical problems that 1, the solid metal rod has poor heat dissipation effect, so that the inner layer of the plastic pipeline cannot be rapidly cooled, and when the solid metal rod enters a winding machine, the inner layer of the plastic pipeline with too high temperature causes the reinforcing belt to deform, so that the reinforcing belt cannot be completely coated on the surface of the inner layer of the plastic pipeline, and the winding effect of the reinforcing belt is poor; 2. because the core rod can not fast dispel the heat to the plastic conduit inlayer, in the traction process, the plastic conduit inlayer can glue on the core rod, leads to the core rod to separate with the plastic conduit inlayer more difficultly, produces great influence to whole production technology.
In summary, in order to solve the technical problems of the mandrel, a mandrel structure for plastic pipe forming needs to be designed, which has a simple structure, a good heat dissipation effect and is easy to separate.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem that prior art exists, provide a simple structure, radiating effect good and easy separation be used for fashioned plug structure of plastic conduit.
The purpose of the utility model can be realized by the following technical proposal: a mandrel structure for forming plastic pipes comprises
