AI Technical Summary

Technical Problem

Existing pipe bending systems are prone to producing defective products when processing asymmetrical metal pipes, especially those caused by incorrect installation or supply direction of flared nuts.

Method used

A pipe bending processing system was designed, comprising a bending machine, a pipe feeder, and an inspection mechanism. The system detects the installation direction and supply direction of the flared nut through end-connection operations, and uses a camera unit and image processing technology to detect abnormalities, ensuring that the flared nut and the annular protrusion are correctly aligned and preventing the production of defective products.

Benefits of technology

Detecting and eliminating abnormalities before bending processes prevents the generation of defective products, improves processing efficiency and product quality, and reduces the number of defective products.

Abstract

Disclosed is a pipe bending system that bends a pipe to be processed into a prescribed shape, the pipe to be processed including a metal pipe and two horn nuts. The pipe bending system includes a bending machine and a pipe supply machine. The pipe supply machine includes a termination mechanism that performs a termination operation of moving the two horn nuts to the end portion side of the pipe to be processed for the pipe to be processed, so as to bring one of the two horn nuts into abutment with one of the two annular protrusions and bring the other of the two horn nuts into abutment with the other of the two annular protrusions, and an inspection mechanism that detects an abnormality of the pipe to be processed that should be bent by the bending machine using the termination operation.
