  • Publication number: 20190283184
    Abstract: The present invention discloses a laser shock forging and laser cutting composite additive manufacturing device and method. The device forms two different light guide systems by splitting an output laser beam of a laser device into two laser beams through a beam splitter system. The first light guide system splits a laser beam into a third laser beam and a fourth laser beam which are respectively applied to laser 3D (3-Dimensional) printing and laser cutting. The second laser beam is applied to laser shock forging. A three dimensional model is built according to individual design requirements of a part. Layer-by-layer slicing treatment is performed to acquire slice contour information, so as to determine a layered contour and internal complex structures such as a cavity, a pipeline and a cold pipe of the part through laser cutting. The third laser beam forms an Nth layer of slice through 3D printing, and the second laser beam performs synchronous laser shock forging in an optimal temperature region.

  • Publication number: 20190047050
    Abstract: A method for composite additive manufacturing with dual-laser beams for laser melting and laser shock, includes the following steps: 1) performing cladding on metal powder through a first continuous laser beam by thermal effect, and performing synchronous shock forging on material in a cladding region through a second short-pulse laser beam by shock wave mechanical effect, so as to perform the composite additive manufacturing; and 2) stacking the material in the cladding region layer by layer to form a workpiece. The method has the characteristics that the two laser beams make full use of the thermal effect and the shock wave mechanical effect, and synchronously work in a coupled manner, so that defects such as pores, incomplete fusion and shrinkage in a cladding layer are eliminated, and the performance of the workpiece is obviously improved. The method is high in manufacturing efficiency.

  • Publication number: 20190039184
    Abstract: A strengthening laser device of the present disclosure may freely move on both sides of a workpiece, so that a correcting laser device and the strengthening laser device are distributed on the same side or both sides of the workpiece. The correcting laser device performs a correcting procedure, and the strengthening laser device performs a strengthening procedure. An online monitoring system monitors the surface performance, a shape and a size of the workpiece. A real-time tracking feedback system feeds back the data monitored by the online monitoring system to a correcting laser device power adjustment apparatus and a strengthening laser device power adjustment apparatus for automatic compensation, so that a synergetic influence caused by synchronous correcting and strengthening for the workpiece is eliminated. The surface accuracy of the workpiece is improved, and the machining efficiency is increased to a large extent at the same time.
