Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with specific embodiments.
[0025] figure 1 It is a schematic diagram of the structure of the variable-wall-thickness sheet metal parts processing device based on 3D printing and incremental forming technology. The variable-wall-thickness sheet metal parts processing device based on 3D printing and incremental forming technology includes incremental forming chuck 1 and incremental forming tool head 2 , a laser beam 3 and a powder spray head 4 . The powder nozzle 4 sprays powder on the sheet where the wall thickness needs to be increased or where it is easy to become thinner during the forming process. The laser beam 3 is used to clad the powder on the surface of the sheet to increase the thickness of the material. For other parts, there is almost no thinning or no In the area where the wall thickness needs to be increased, the powder feeding operation is not performed; at the same time, the laser ...
