Metal molten drop deposition method implemented by using nonmetal sheets with trapezoidal grooves

Abstract

The invention discloses a metal molten drop deposition method implemented by using nonmetal sheets with trapezoidal grooves. The metal molten drop deposition method comprises the following steps: firstly, arranging nonmetal sheets with trapezoidal grooves on the four side faces of a baseplate, and preheating the baseplate on which the nonmetal sheets with trapezoidal grooves are arranged; then, heating a metal material until the metal material is in a molten state, enabling the molten-state metal material to pass through a nozzle so as to form uniform metal molten drops; and in an argon gas environment, dropwise adding the metal molten drops on the surface of the baseplate on which the nonmetal sheets with trapezoidal grooves are arranged, and moving the baseplate on which the nonmetal sheets with trapezoidal grooves are arranged according to the shape of the surface of the baseplate, so that the metal molten drops are deposited layer by layer and point and point, and meanwhile, blocking the edge of each layer of metal molten drops through the nonmetal sheets with trapezoidal grooves until the metal molten drops are deposited completely, and after the obtained product is subjected to curing shrinkage, completing the metal molten drop deposition of the surface of the baseplate. According to the metal molten drop deposition method disclosed by the invention, the precision of metal molten drop deposition on the surface of the baseplate can be realized.

Description

technical field [0001] The invention relates to a metal droplet deposition method, in particular to a metal droplet deposition method using a non-metal sheet with trapezoidal grooves. Background technique [0002] At present, many scientific research institutes at home and abroad, such as the MicroFab commercial company in the United States, the University of Toronto in Canada, Northwestern Polytechnical University in China, and Huazhong University of Science and Technology, etc., mainly focus on the droplet deposition mechanism, driving mode selection and Thermal state analysis of metal droplet dripping process and other aspects. However, there are few studies on how to ensure the precision of droplet deposition and forming. [0003] The accuracy of parts, the performance of raw materials and processing efficiency are three important factors restricting the droplet forming process and its application. In the process of fused deposition, because complex three-dimensional p...

Problems solved by technology

However, the processing of such small thin-walled parts is more difficult in the traditional processing technology, because the wall is thin, the rigidity is poor, the strength is low, and the deformation is large, it is difficult to guarantee the processing quality in the processing operation, and the surface accuracy is difficult. master

For large-scale production, we can use the processing characteristics of CNC lathes, such as high machining accuracy and high production efficiency, but in terms of workpiece clamping, processing tools, and programming, etc., due to the different structural shapes of parts. Encountered difficulties, could not find a way to effectively overcome the influence of part deformation, and could not guarantee the accuracy requirements of the processed parts
