AI Technical Summary

Technical Problem

Existing welding deburring equipment suffers from easily damaged cutting tools that are difficult to adapt to steel pipes of different diameters, resulting in high production costs and complex management.

Method used

Design a welding scab removal mechanism that employs a main cutter post and a secondary cutter post working in tandem. The main cutter post is responsible for overall planing, while the secondary cutter post is responsible for fine-tuning. The mechanism combines an arc-shaped blade with the outer wall of the steel pipe and improves adaptability and efficiency through angle adjustment and an automatic material collection device.

Benefits of technology

Extend tool life, reduce production costs, improve welding quality and efficiency, adapt to steel pipes of different diameters, realize automated wire collection, reduce process transfer, and ensure the flatness of steel pipe surface.

Abstract

The utility model provides a kind of welding scarfs mechanism to solve the problem that tool is easily damaged. Scarfs mechanism includes rack, and the side of rack is equipped with feeding device, and rack is equipped with support piece, and rack includes lifting frame, and the bottom of lifting frame is fixed with main tool rest, and the side of main tool rest away from feeding device is equipped with multiple vice tool rest, and vice tool rest is located at the both sides of steel pipe respectively, and main tool rest or vice tool rest includes fixed plate, and inner slide has handle, and the side wall of fixed plate is equipped with limit plate, and the bolt is screwed on limit plate, and bolt is abutted with handle, and the bottom of handle is equipped with blade, and blade includes main blade and vice blade, and the cutting edge of main blade is perpendicular to the axis of the pipe to be polished, and the cutting edge of vice blade is obliquely arranged to welding line, and the end of vice blade cutting edge close to welding line is towards feeding device. The utility model can simultaneously plane multiple parts of steel pipe weld by the synergistic effect of main tool rest and vice tool rest, and reduce the resistance received by single tool in the process of planing.
