Abstract

The present invention discloses a laser compounding and forming method for bending, which includes steps below: 1) Simulating processing is carried out to billets through a computer platform and partial area hard to be formed is prejudged; 2) Laser processing parameters are obtained according to step 1); 3) Lasers are controlled to realize composite processing through a computer control system according to parameters in step 2) during mechanical processing; 4) Synchronous with the processing in step 3), a sensor for billet state measuring feeds stress, strain and other real-time monitoring data back the control system; 5) As for a fine adjustment scheme, a fine adjustment scheme is firstly confirmed according to step 1), 2), 3) and 4) and then the scheme is controlled by a computer to complete processing. The present invention applies lasers to achieve laser compounding and forming for bending during large-sized piece forming of traditional machinery, well processes parts hard to be reshaped during mechanical forming, thus eliminating possible formed piece flaw and even damages due to mechanical forming.

Description

technical field

[0001] The invention relates to a bending forming method of sheet metal structural parts, especially difficult-to-form sheet metal structural parts with large size and complex structure shape. Background technique

[0002] There are such types of sheet metal parts in engineering, such as aircraft skin and overall (integrated skin and support ribs) panel parts, rocket integral fuel tank parts, ship side and deck parts, and car coverings, etc. , It needs to be formed by bending or rolling (another form of bending, the formed part can be rotated with the support roll while being bent).

[0003] Press bending or roll bending is the main method of forming wall panels at present. The method uses a three-point bending method to form the wall plate, the wall plate is supported by two supporting points, and the loading device controls the pressure head to load on the predetermined position on the wall plate. The siding deforms plastically under the load to achieve t...
