Compound ultrasonic fusion deposition additive-manufacturing device and compound ultrasonic fusion deposition additive-manufacturing method

Abstract

The invention relates to a compound ultrasonic fusion deposition additive-manufacturing device and a compound ultrasonic fusion deposition additive-manufacturing method, and belongs to the technical field of additive manufacturing. An ultrasonic enhancement device is fixed to a guide rod I and a guide rod II of an ultrasonic support platform; a moving base plate is installed on a guide rail I and a guide rail II of an X-directional guide connection system, and fixed to a synchronous belt simultaneously; the moving base plate is driven to move through an X-directional motor; and a fusion deposition additive-manufacturing system and the ultrasonic support platform are connected through a connection rod I and a connection rod II in the X-directional guide connection system. Parts with poor adhesion among fusion deposition wire materials and between the deposition wire materials and a deposition layer can be re-melted by virtue of ultrasonic vibration, and the deposition wire materials in formed parts are compounded into one piece, so that the comprehensive mechanical property of fusion deposition additive-manufactured parts, and in particular, the mechanical strength in the vertical direction of a forming axis, is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and specifically relates to an ultrasonic fusion deposition additive manufacturing device and method, which can significantly enhance the comprehensive mechanical properties of the fusion deposition additive manufacturing parts by ultrasonically strengthening the fusion deposition additive manufacturing parts, especially along the forming process. Intensity in the direction perpendicular to the axis. Background technique [0002] Additive manufacturing technology is changing our production and lifestyle. Many developed and developing countries attach great importance to and actively promote this technology. Fused deposition manufacturing (FDM) is a relatively mature additive manufacturing technology. Scott Crump proposed the idea of ​​fused deposition manufacturing in 1988, and developed the first commercial model 3DModeler in 1992. Fused deposition manufacturing is a fast additiv...

Problems solved by technology

[0003] The invention provides a device and method for ultrasonic fusion composite deposition additive manufacturing to solve the problem that the mechanical properties of parts formed by the existing fusion deposition additive manufacturing technology are anisotropic, the mechanical strength along the vertical direction of the forming axis is relatively weak, and the resistance of the formed parts is relatively weak. The shear performance is poor, and the temperature of the forming chamber is required to be high during the forming process.
