Flaring device for thermoplastic plastic composite pipe

Abstract

The invention relates to the related technical field of pipe processing, and discloses a flaring device for a thermoplastic plastic composite pipe, which comprises a transmission screw rod, the side wall of the transmission screw rod is in threaded connection with a positioning seat, the top end of the transmission screw rod is movably provided with an adjusting arm, and one end of the transmission screw rod is fixedly provided with a fixed disc; a scraper used for cutting the interior of the pipe fitting is movably installed at the bottom end of the fixing disc, and the positioning base is a cylinder with the side wall being provided with an inclined face. By arranging the positioning seat, the transmission lead screw and the scraper, when a plastic pipe fitting is subjected to reaming, the scraper stretches into the pipe fitting, reaming from inside to outside of the pipe fitting is achieved through rotation of the transmission lead screw, and meanwhile, the positioning seat can be subjected to tension generated when the scraper conducts reaming outwards, so that the pipe fitting is subjected to reaming, and the reaming efficiency is improved. Therefore, the side wall of the positioning seat is inserted into the inner wall of one end of the pipe fitting, the inclined part of the side wall of the positioning seat is inserted into one end of the pipe fitting to form accurate positioning, and finally the purposes of reaming from inside to outside and stable positioning are achieved.

Description

technical field [0001] The invention relates to the related technical field of pipe material processing, in particular to a flaring device for a thermoplastic composite pipe. Background technique [0002] Plastic pipes are generally made of synthetic resin as raw materials, adding stabilizers, lubricants and plasticizers, and extruding them in a pipe-making machine by a "plastic" method. Drainage, exhaust, sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, etc. [0003] In the process of using plastic pipes, the phenomenon of inconsistent wall thickness of plastic pipe fittings will occur, so there is a problem of different sizes of inner diameters. As a result, after the pipe fittings are squeezed and installed, the installation part is placed in the position where the pipe diameter changes, so that the connection port is easy to be connected. The phenomenon of rupture caused by the impact of the medium, although the inner wall of the pipe is cut of...
