Abstract

An ultrasonic in-situ loading device for laser melting deposition shaping, relating to an ultrasonic in-situ loading device for laser melting deposition shaping. The purpose is to solve the problem that the directional solidification structure is easily produced in the forming process of the existing laser melting deposition equipment. The device is composed of a base plate, a temperature control board, an air-cooled chamber, a water-cooled chamber, a fixed base and an ultrasonic vibrator. The device of the invention generates a high-frequency ultrasonic field during the laser melting deposition forming process, realizes the homogenization of the structure of the shaped product and the refinement of the crystal grains, and improves the strength of the laser melting deposition product. At the same time, the present invention realizes the adjustable temperature of the substrate by providing a temperature-adjustable temperature control plate under the substrate. The invention is suitable for laser melting deposition shaping.

Description

technical field [0001] The invention relates to the technical field of metal laser melting deposition forming equipment, in particular to an ultrasonic in-situ loading device for laser melting deposition forming. Background technique [0002] With the continuous deepening of the concept of green sustainable development, 3D printing technology has greatly reduced the waste of raw materials with its unique additive forming method, and has become an advanced manufacturing technology with great development prospects. As an important development direction of 3D printing technology in the metal field, laser melting deposition technology adopts the working method of coaxial laser powder feeding, and realizes the forming of metal products channel by channel and layer by layer under computer control. During the working process of the laser melting deposition equipment, the metal powder and the protective gas are ejected from the nozzle of the laser melting deposition equipment synchr...
