Abstract

The invention relates to an ultrasonic in-situ loading device for laser melting deposition forming, in particular to the ultrasonic in-situ loading device for laser melting deposition forming. The invention aims to solve the problem that directional solidification structures can be easily generated in the forming process of existing laser melting deposition equipment. The device is composed of a base plate, a temperature control plate, an air cooling bin, a water cooling bin, a fixed base and an ultrasonic vibrator. According to the device, a high-frequency ultrasonic field can be generated in the laser melting deposition forming process, homogenization and grain refinement of the structure of a formed product are achieved, and the strength of the laser melting deposition product is improved. Meanwhile, the temperature control plate capable of adjusting the temperature is arranged below the base plate so that the temperature of the base plate can be adjusted. The device is suitable for laser melting deposition forming.

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...
