摘要电弧增材制造技术正在成为研究的热点，如何提高增材制造熔敷的效率和质量成为研究的难点之一。本文在传统等离子弧单填丝的基础上，尝试开发机器人双填丝等离子弧自动增材制造方法和装置，实现同种材料的高效堆敷和异种材料复合制造的目的。本课题首先设计了机器人双填丝等离子弧自动增材制造系统方案，选择了合适的送丝机，并设计制作了双填丝的三维调节送丝机构，将其与机器人，焊接电源、等离子焊枪等设备进行组装调试，形成了双填丝机器人PAW电弧自动增材制造系统。然后采用H08Mn2Si和H00Cr21Ni10丝材，分别进行了等离子电弧H08Mn2Si单填丝和双填丝对比试验、H00Cr21Ni10单填丝和双填丝对比试验、H08Mn2Si和H00Cr21Ni10丝材同步堆敷试验研究，分析了成型尺寸特征和成型效率。最后进行了二种丝材的交替堆敷试验，堆敷了单层交替堆敷样件和多层“井”字试验件。87879

Title    The twin-wire feeding robot PAW arc automatic gain  material  gain material Manufacturing system     

Abstract The wire-arc additive manufacturing process is becoming a research hotspot,and how to improve the efficiency and quality of it is one of the difficulties。Based on the traditional  plasma arc on the single wire filling,this paper try to develop the twin-wire feeding PAW arc automatic gain material manufacturing system methods and means to achieve the purpose of efficient welding of the same materials and composite manufacturing of different materials。First,we designed the solutions of the twin-wire feeding robot PAW arc automatic gain material manufacturing system,and select the appropriate wire feeder。Then, we designed a three-dimensional adjustment which can deliver two wire simultaneously。Last ,the wire feeder,the robot,the welding power source and the plasma torch were assembled and debugged,and they form the twin-wire feeding robot PAW arc automatic gain material manufacturing system。In order to verify the feasibility of the system,we chose  H08Mn2Si wire and H00Cr21Ni10 wire to conducted the comparative test of the differences between single filler and double filler wire,and also test the composite manufacturing of different materials。Then,we analyzed the forming characteristic size and forming efficiency。Last,two kinds of wire alternately surfacing test was conducted to obtain alternately single composting sample and composting sample of multilayer "well"。
