Method for rapid prototyping by taking wire as raw material and rapid forming machine

Abstract

The invention discloses a method for rapid prototyping by taking a wire as a raw material and a rapid forming machine. The method includes that firstly, the wire is pulled on a forming board to form a linear or curved flat trajectory shape to be combined on the forming board and kept in the corresponding shape; secondly, the wire is taken as a benchmark to perform rapid prototyping layering to have the wire stacked up and increased, two situations are included in that 1), other wires are tightly stacked up on the wire to form a space shaped needed by components, the wires are metallurgically combined therein, and the components required in shape can be finally obtained; 2), the other wires and the wire are adhered side by side to form a panel structure, metallurgical combination among the wires is achieved, the wires on the panel structure are stacked up in layer according to required trajectory shape and length to form the space shape required by the components, metallurgical combination among the wires is achieved, and the components required in shape are finally obtained. The method is convenient to operate, stable and reliable and low in production cost.

Description

technical field [0001] The invention relates to the technical field of rapid prototype manufacturing, in particular to a method for rapidly manufacturing a prototype using silk as a raw material and a rapid prototyping machine thereof. Background technique [0002] Rapid prototyping, also known as rapid prototyping, takes wire as the feed material. Metal welding wire three-dimensional welding cladding rapid prototyping technology is a kind of rapid parts manufacturing technology. It is a manufacturing method of layer-by-layer welding accumulation growth forming, which can be directly manufactured High-melting-point metal prototypes, while other rapid prototyping methods using wire as raw materials can only manufacture plastics, polymer materials, and low-melting point metal prototypes (see "Rapid Prototyping Technology", Wang Yungan, Huazhong University of Science and Technology Press, 1999 September 1st edition, pp. 81-83); while metal powder 3D printing is very slow and in...

[0002] Rapid prototyping, also known as rapid prototyping, takes wire as the feed material. Metal welding wire three-dimensional welding cladding rapid prototyping technology is a kind of rapid parts manufacturing technology. It is a manufacturing method of layer-by-layer welding accumulation growth forming, which can be directly manufactured High-melting-point metal prototypes, while other rapid prototyping methods using wire as raw materials can only manufacture plastics, polymer materials, and low-melting point metal prototypes (see "Rapid Prototyping Technology", Wang Yungan, Huazhong University of Science and Technology Press, 1999 1st edition, September, pages 81-83); while metal powder 3D printing is very slow and inefficient, and the parts have the characteristics of powder metallurgy parts, the mechanical properties of the material are low, and the impact resistance is not strong
