Problems solved by technology

The high temperature during the cutting process will also cause thermal deformation of the sheet metal, which is not suitable for precision processing
Except in the field of cutting and welding, there is currently no application of laser technology in the field of plastic forming of sheet metal, especially the incremental forming process.

Abstract

The invention relates to an ultrahigh pressure water jetting sheet material progressive processing spray nozzle based on laser auxiliary heating and application thereof. The spray nozzle comprises a lower sleeve, a jet nozzle, an intermediate sleeve, a laser output device and an upper sleeve. The lower sleeve, the jet nozzle, the intermediate sleeve are successively connected with the upper sleeve that is in a double-layer structure. The laser output device is fixed on the upper sleeve and an output optical axis is right opposite to the jet nozzle. According to the invention, progressive forming or cutting can be carried out on materials like titanium alloy, wherein the materials are difficult to be formed.

Description

technical field [0001] The invention relates to a device in the technical field of sheet metal forming and its application, in particular to an ultra-high pressure water jet sheet progressive processing nozzle based on laser-assisted heating and its application. Background technique [0002] Metal sheets are widely used in aviation, aerospace, automobile, shipbuilding and other manufacturing industries. The traditional sheet metal stamping forming method is suitable for mass production and processing, but for small batches, multi-variety and sample trial production processing, a new technology has emerged in recent years. A method for incremental forming of sheet metal. This method does not need to make a special stamping die for the product, has the characteristics of flexible processing methods, high forming limit, and low processing cost, and is especially suitable for the processing and production of small batches of metal plates. [0003] The current incremental formin...
