A high-performance thermoplastic pipe flaring device and method

Abstract

The invention discloses a high-performance thermoplastic pipe flaring device, which includes a base, a feeding mechanism, a flaring die and several pipe clamps for clamping high-performance thermoplastic pipes, the flaring die is arranged on the base, and the flaring die A heating rod is arranged on the top of the pipe clamp, and a horizontal connecting rod is fixed on the outer wall of the pipe clamp. The end of the connecting rod far away from the pipe clamp is provided with a first connecting hole. The feeding mechanism includes a crank handle and several vertically arranged fixed rods , the fixed rod is provided with a second connecting hole corresponding to the first connecting hole, and the rocker is connected to each fixed rod through a gear transmission mechanism. Turning the rocker can drive the fixed rod to rise and fall vertically, and the connecting rod and the fixed rod are fixedly connected by bolts. Bolts pass through the second connection hole and the first connection hole. The high-performance thermoplastic pipe flaring device and method of the present invention improve the quality of pipe flaring, and effectively avoid defects such as deviation of diameter, cracks, scratches, etc. at the flaring position of the pipe.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a high-performance thermoplastic pipe flaring device and method. Background technique [0002] High-performance thermoplastic pipes such as polyether ether ketone (PEEK), polyether ketone ketone (PEKK), polyarylether ketone (PAEK), polyphenylene sulfone (PPSU), polyetherimide (PEI), polyphenylene Sulfide (PPS), polyphenylene oxide (PPO), etc. are widely used in the fields of aviation, aerospace and nuclear industries due to their high temperature resistance, chemical solvent resistance, low temperature resistance, radiation resistance, aging resistance, and high mechanical properties. Replacing aluminum alloy pipes to achieve structural weight reduction. Flare connection is the main connection method of pipeline system in aviation, spaceflight and nuclear industry. In order to ensure the safety and airtightness of pipelines in high-pressure systems such as hydraulic pre...

AI Technical Summary

Problems solved by technology

However, in actual production, after the pipe is flared, affected by the flaring process parameters or the material of the pipe itself, defects such as deviation, cracks or scratches are prone to occur on the surface of the flared end, which seriously reduces the quality of the pipe flare. The stability and the qualified rate of flaring even affect the safety of the material during use
