AI Technical Summary

Technical Problem

When the existing flame cutting device cuts rusty pipe fittings, rusty substances interfere with the cutting flame, causing blurred and residual cuts, affecting subsequent processing and use, and is prone to splashing and contamination during cutting.

Method used

The rust removal mechanism and an isolation mechanism are adopted to drive the rotating shaft to drive the auxiliary roller and the polishing belt to rotate through the brake stepper motor to automatically polish and remove rust. The surface of the pipe fitting is heated by conducting conductively to isolate the splash and dust during cutting with an annular airbag.

Benefits of technology

It realizes comprehensive automatic grinding and rust removal of pipe fitting surfaces, improves cutting quality and efficiency, prevents splashing and dust pollution, and extends the service life of the equipment.

Abstract

The invention relates to the technical field of flame cutting machine tools, in particular to an anti-splashing automatic flame cutting device which comprises a cutting table, and a pipe conveying assembly and a pipe output assembly are symmetrically installed at the top end of the cutting table. According to the anti-splashing automatic flame cutting device, a band-type brake stepping motor drives a rotating shaft to rotate, so that a plurality of auxiliary rollers and driving rollers which are arranged in a cavity ring in a surrounding mode at equal angles synchronously rotate, a polishing abrasive belt is driven to synchronously rotate, and therefore the to-be-cut face of a pipe fitting can be comprehensively wrapped and effectively and automatically polished and derusted; the whole cutting quality is guaranteed, subsequent machining and using are prevented from being affected, meanwhile, a limiting gear ring can drive a plurality of abutting blocks on the side edge to rotate synchronously when rotating, and therefore the roller rods are abutted against and make reciprocating motion, and the cutting efficiency is improved. And meanwhile, when the roller rod reciprocates, a certain amount of rust remover in the liquid storage tank can be intermittently sprayed out of the spray head to be sprayed on the surface of the running polishing abrasive belt, the polishing and rust removing effect is improved, and efficiency is improved.
