Description

technical field [0001] The invention relates to a three-dimensional synchronous loading device for ultrasonic-assisted laser melting deposition forming of large-volume parts. Background technique [0002] With the development of metal additive forming technology and forming equipment, parts manufactured by additive forming technology have been widely used in aerospace, automotive parts, medical equipment and other fields. Laser melting deposition technology is a high-tech metal additive Material forming technology has also been greatly developed. Laser melting deposition technology is a rapid solidification technology. A large number of oriented crystal structures will be formed in the parts formed by laser melting deposition technology. This phenomenon is particularly prominent when forming large-volume parts. Due to the large volume of the formed parts, the internal temperature distribution of the parts is not uniform during the forming process, and there is a great tempe...
