Abstract

The invention discloses a portable small-caliber steel plastic complex pipe expanding machine, relating to the field of pipe expanding technology. The portable small-caliber steel plastic complex pipe expanding machine mainly comprises a manual hydraulic mechanism and a clamping device, wherein a steel plastic complex pipe is fastened by the clamping device, a pressure head is driven by utilizing the manual hydraulic mechanism, by utilizing the characteristics that the steel plastic complex pipe is good in ductility and capable of being profiled and stamped, hydraulic power pushes the profiled expanded pressure head, so that the end opening of the steel plastic complex pipe is expanded according to the appearance of the profiled pressure head. The invention relates to a device which is used for expanding the end opening of the steel plastic complex pipe, is simple in structure and consists of the hydraulic mechanism and the profiled pressure head, thus well meeting the applications of an expanding pipe fitting for the small-caliber steel complex plastic pipe in the connection of the steel plastic complex pipes; consumable accessories are not adopted for the device, so that the continuous operation capability of the device can be enhanced, and the installation and construction efficiency of the steel plastic complex pipe can be improved.

Description

technical field [0001] The invention relates to the technical field of pipe flaring, in particular to a device for flaring the port of a steel-plastic composite pipe by using a manual hydraulic mechanism and a profiling indenter. Background technique [0002] The steel-plastic composite pipe industry is an emerging industry that has just developed in recent years. It is favored by many manufacturers and users because of its high pressure bearing capacity, low price, good corrosion resistance, and small linear expansion coefficient. Flared pipe fittings for steel-plastic composite pipes have the characteristics of high reliability and high pressure bearing capacity among the various types of pipe fittings used in steel-plastic composite pipes, and are widely used in the connection of steel-plastic composite pipes. [0003] In the prior art, the flaring of the port of the metal pipe fitting usually adopts a thermal expansion method, which requires a heating device, and has the...
