[0002] The metal laser direct deposition synchronous forging device is an advanced manufacturing technology that combines additive manufacturing and forging processes. It significantly improves the density, strength and fatigue resistance of metal parts by simultaneously realizing the deposition forming and mechanical property optimization of metal materials. Among them, laser direct deposition (DED) technology uses high-energy laser as a heat source to melt metal powder or wire, and accumulates layer by layer to form metal parts. Compared with traditional casting, its heat input is more concentrated and the cooling speed is faster, but it is easy to produce defects such as pores and cracks due to rapid solidification. The synchronous forging process is to apply a force field to the molten pool or solidified layer through mechanical forging or laser shock wave during or after the deposition process to achieve grain refinement, defect repair and residual stress control.

[0003] The existing metal laser direct deposition synchronous forging device is prone to excessive up and down movement stroke or horizontal left and right shaking during the forging process, affecting the forging accuracy and forging quality. Therefore, a metal laser direct deposition synchronous forging device is needed, which is conducive to adjusting the forging movement stroke in the vertical direction, eliminating the shaking in the horizontal direction, and maintaining the stability of forging.
