AI Technical Summary

Technical Problem

After hot-melt welding, the flange on the inner wall of plastic pipes will reduce the water flow diameter and become a blockage point, especially for sewage pipes, which are prone to accumulating garbage.

Method used

A cutting device for pipe manufacturing and processing is provided, including a fixed base, an end face cutting component, a molten pool cutting component, and a rotating component. Through rotation and extension movements, it cuts the molten pool and end face of the inner surface of the pipe, ensuring that the end face is perpendicular to the central axis and removing the oxide layer.

Benefits of technology

Thoroughly remove the molten pool on the inner surface of the pipe to avoid internal blockage, improve water flow, and ensure smooth and clean pipe connections.

Abstract

The utility model relates to a cutting device for pipe production and processing, which comprises a fixed seat, an end face cutting component, a molten pool cutting assembly, a telescopic component and a rotating component, the end face cutting component and the molten pool cutting assembly are arranged on the upper end face of the fixed seat, and the telescopic component is arranged on the lower end face of the fixed seat; the rotating part is arranged at the other end, away from the fixing base, of the telescopic part, the telescopic part penetrates through the fixing base to be connected with the molten pool cutting assembly, the rotating part drives the end face cutting part to rotate, and the end face cutting part cuts the end face of the open end of the pipe so that the end face of the open end of the pipe can be perpendicular to the central axis of the pipe. The rotating component drives the molten pool cutting assembly to rotate, the molten pool cutting assembly conducts circumferential cutting on a molten pool on the inner surface of the pipe, the telescopic component drives the molten pool cutting assembly to move along the central axis of the pipe, and the molten pool cutting assembly conducts longitudinal cutting on the molten pool on the inner surface of the pipe. And the blockage problem caused by flanging of the inner surface of the pipe is avoided.
