Abstract:
1. A system for manufacturing integrated sockets in biaxially oriented plastic pipes, the system comprising: a support body configured to couple the pipe to a mould, a slide block coaxial with and axially slidable in said support body, a slide rod configured to push against the direction of extrusion of a blank or the plastic pipe and further configured to slide axially within the slide block, wherein said slide rod includes an axial central orifice configured to permit the intake and outlet of fluids and also includes a fastener configured to immobile the blank or the plastic pipe during an orientation or expansion process of the blank or the plastic pipe, wherein said slide block includes an inner end with an outer conical configuration, a heater configured to heat the slide block, and small orifices extending axially in the slide block for a lubricating fluid; and actuators configured to axially displace the slide block and slide rod, and to control relative speed between the slide block and the slide rod to obtain desired thicknesses of the socket formed during the expansion and distribution of the material of the blank or the plastic pipe.
