AI Technical Summary

Technical Problem

The existing dust removal systems of laser tube cutting machines cannot effectively remove the smoke, debris, and residue generated during the tube cutting process, resulting in environmental pollution and a decline in equipment performance.

Method used

A dust removal system combining a fixed dust hood, positive pressure blowing, and negative pressure collection was designed. The fixed dust hood adsorbs suspended dust, the positive pressure blowing unit removes high-temperature molten slag, and the negative pressure collection unit collects molten slag and debris in the pipe, achieving efficient cleaning throughout the entire process.

Benefits of technology

It achieves simultaneous and efficient removal of smoke, slag, and debris, reducing the impact on subsequent processing and improving the cleanliness and efficiency of the equipment.

Abstract

A dust removal system for a laser pipe cutting machine comprises a dust remover, a slag removal mechanism and a fixed dust hood, the fixed dust hood is arranged on the periphery of a laser cutting head, the bottom side of the fixed dust hood is connected to the dust remover, a front chuck and a rear chuck and used for clamping a pipe to be cut, and an air blowing opening is additionally formed in the tail end of the rear chuck. And one part of the deslagging mechanism can stretch into the pipe to be cut. According to the utility model, the fixed dust hood, positive pressure blowing negative pressure collection and pipe inner wall slag removal are combined, the fixed dust hood adsorbs suspended smoke dust, the positive pressure blowing unit peels off high-temperature slag, and the negative pressure collection unit collects slag and chippings in the pipe, so that efficient cleaning in the whole process of smoke dust-slag-chippings is realized.
