AI Technical Summary

Technical Problem

It is difficult for existing welding equipment to effectively locate and weld bended metal pipe fittings, especially when the diameters of the two ends of the pipe fittings are different, resulting in low welding efficiency.

Method used

A pipe bending welding equipment including a rotating mechanism, a pushing mechanism, a positioning mechanism and a detection mechanism is designed. Through the airbag limit, the coordination of the push plate and the turntable, adaptive alignment of the bent pipe and the straight pipe is achieved, and efficient welding is achieved through the combination of electric welding torch and rollers.

Benefits of technology

It improves the efficiency and adaptability of bent pipe welding, can automatically complete the alignment of bent pipe and straight pipe, and ensures the welding quality through the inspection mechanism.

Abstract

The invention belongs to the technical field of welding, and particularly relates to bent pipe welding equipment for metal pipe fittings, which comprises two workbenches, the top of the right workbench is connected with a placing frame with a triangular groove, the placing frame is rotatably connected with two rows of lower rollers at the triangular groove, and the top of the right workbench is connected with a vertical rod. A lifting plate driven by an electric push rod is slidably connected to the vertical rod, a pair of upper rollers is rotatably connected to the lifting plate, and a sliding rod sliding up and down is arranged on the front portion of the lifting plate. The bent pipe on the supporting disc is limited through the expanded air bag, a straight pipe is placed on the two rows of lower rollers, after the straight pipe is aligned with a pipe opening of the bent pipe, the upper rollers, the electric welding gun and the rolling wheels descend, the rolling wheels and the upper rollers make contact with the surface of the straight pipe, the relative positions of the rolling wheels and the upper rollers can adapt to the pipe diameter of the straight pipe under the action of the compression springs, adaptability is high, and welding efficiency is high. The rotating shaft, the supporting disc, the air bag, the bent pipe and the straight pipe integrally rotate, meanwhile, the electric welding gun conducts welding work, and the welding efficiency is high.
