The shape and property integrated metal component additive manufacturing system comprises an object carrying platform, a multi-electric arc collaborative operation module, an electric arc camera shooting detection unit, a forming size three-dimensional measurement unit, a depositing forming digital monitoring module and the like, and uniform control is executed through a negative feedback monitoring module. The multi-electric arc collaborative operation module is equipped with a plurality of mutually independent electric arc guns, and relative positions and operating postures of the electric arc guns freely change. Through the shape and property integrated metal component additive manufacturing system, electric arc additive manufacturing overall processes of various large metal components can be executed based on a compact structure, convenience in control, high automaticity and high manufacturing accuracy, and the requirements of shape and property integrated collaborative additive manufacturing are met better.

Description

technical field [0001] The invention belongs to the technical field related to additive manufacturing, and more particularly relates to a form-property integrated metal component additive manufacturing system. Background technique [0002] Arc melting metal wire additive manufacturing technology is a rapid additive manufacturing method that uses an arc as a heat source to melt metal wire, and makes the melted wire continuously pile up and form according to the set forming path. Because the arc melting metal wire additive manufacturing technology has the characteristics of low cost, high efficiency, and arbitrary curved surface forming in space, it has been widely used in the manufacturing and forming of various large and complex metal components. [0003] However, further studies have shown that the arc melting metal wire additive manufacturing equipment in the prior art still has the following defects or deficiencies: First, most of the current equipment uses the structure ...

Problems solved by technology

[0003] However, further studies have shown that the arc melting metal wire additive manufacturing equipment in the prior art still has the following defects or deficiencies: First, most of the current equipment uses the structure of an arc welding power source plus a robot, and its components are complex. Difficult to control; secondly, manual programming or offline programming is often used in the additive manufacturing process. The size and quality of the stacked formed components are generally detected after the forming is completed, using some subsequent testing equipment and methods to detect the formed size and performance, which cannot be realized. Metal components, especially large and complex metal components, are shaped and functionally integrated with collaborative additive manufacturing; finally, in the conventional arc fuse accumulation process, not only is the arc unstable, but the heat accumulation often makes the accumulated formed metal components crystallize. Coarse particles cause performance deterioration and cannot meet the high performance requirements of large metal components
