AI Technical Summary

Technical Problem

When the polyethylene pipe is directly connected, it is difficult to grind out the flat pipe port manually. When it is necessary to grind out the interface of the inclined port, the process is cumbersome and the grinding efficiency is low.

Method used

An ultra-high molecular weight polyethylene pipe connection repair device is designed, including a base, a tool, a motor and a grinding disc. The polyethylene pipe is fixed by rotating the first threaded rod, and the grinding disc is driven by the motor to rotate the grinding disc, and cut and grind the oblique port through the rotating block and the tool.

Benefits of technology

It realizes rapid fixation of polyethylene pipes, and can effectively grind out flat pipe ports and oblique ports, improving grinding efficiency.
