Problems solved by technology

The disadvantage is that strong X-ray radiation will be generated during work, which is harmful to the human body and requires a very thick radiation shielding layer
The advantage of the plasma melting system is that the system is simple and harmless to the human body, the temperature is high, and the disadvantage is that the manufacturing accuracy is low

Embodiment Construction

[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0030] see figure 1 —2 The manufacturing and forming system of resistive double-melting laminated three-dimensional metal components consists of four parts: material release system, melting and forming system, cooling and anti-oxidant delivery system, and high-power power supply. The material release system includes a fuse reel 9 and a fuse reel motor 8. When the forming head 2 is moved to a designated position, the fuse reel motor 8 starts to release the fuse 7 from the fuse reel 9. The cooling and anti-oxidation system consists of an anti-oxidation protection tube 6, an air pump 10, and a liquid inert gas storage evaporation tank 11. After the fuse is released, it enters the anti-oxidation protection tube 6 through the rubber sealing port 14, ...

Abstract

The invention relates to a resistance type double-melting stacking three-dimensional metal member manufacturing forming system and discloses a metal part fast three-dimensional forming system. A resistor is utilized to heat materials, and a secondary re-melting method is adopted to quickly manufacture metal parts. The system is composed of a melting forming system, a material release system, a cooling and antioxidant conveying system and a high-power power supply. The system solves the problem that the existing three-dimensional part manufacturing system is high in cost, low in manufactured part density and poor in quality.

Description

technical field [0001] The invention relates to the field of processing and manufacturing, in particular to a system for rapid three-dimensional forming of metal parts. Background technique [0002] With the advancement of science, "3D manufacturing technology" has developed rapidly and vigorously. The current technology can directly manufacture metal parts, but the produced parts cannot be compared with the same parts produced by traditional cutting due to the low density and voids or debris in the structure. The reason is that the raw materials used in the manufacture of parts are in the form of powder. Taking (SLM) technology as an example, if the metal powder cannot be spread uniformly with the previous layer after laser melting but forms a large number of metal balls, the powder spreading roller will In the process of powder spreading, a large friction force will not only damage the quality of the part, but also hinder the movement of the powder spreading roller in ser...
