A sheet metal laser cutting machine with a pressure transmission nozzle

Abstract

The invention discloses a sheet metal laser cutting machine with a pressure transmission type nozzle, which belongs to the field of transmission. A sheet metal laser cutting machine with a pressure transmission type nozzle includes a laser tube installed on the laser cutting machine body, a laser tube There is a laser nozzle in the inner sliding connection, which can sense the flow and pressure of the air flow and pressure ejected from the laser nozzle through the flexible pressure sensing flap, so that the pressure fine-tuning collar can complete the transmission action, control the distance of the laser nozzle to produce fine-tuning, and increase the pressure of the fine-tuning collar and laser nozzle. The synchronicity of the internal airflow changes, thereby effectively improving the applicability of the laser nozzle. During the cutting process of the laser cutting machine body, it is suitable for the change of its parameters and shapes, and the precise distance of the laser nozzle improves the cutting accuracy of the laser cutting machine body. The processing accuracy of sheet metal parts is improved, and the spatter generated by cutting can effectively avoid the pollution of other accessories.

Description

technical field [0001] The invention relates to the transmission field, and more specifically relates to a sheet metal laser cutting machine with a pressure transmission type nozzle. Background technique [0002] Sheet metal parts are products processed by sheet metal technology. We cannot live without sheet metal parts everywhere. Sheet metal parts are made through filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision Welding, roll forming, metal sheet bending forming, die forging, water jet cutting, among which some sheet metal parts that are not suitable for punching are mostly processed by laser cutting. [0003] Laser cutting is the use of a focused high-power-density laser beam to irradiate the workpiece, so that the irradiated material is rapidly melted, vaporized, ablated or reached the ignition point, and at the same time the molten material is blown away by the high-speed airflow coaxial with the beam, so a...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many factors that affect the accuracy of laser cutting. The most common one is the nozzle distance during laser cutting. During the laser cutting process, its parameters and shapes have certain variability, which makes the flow and pressure inside the nozzle change, but the nozzle after the set distance cannot be fine-tuned, which directly affects the sheet metal parts. The cutting quality is high, and it is easy to cause pollution to other accessories
