Arc fuse additive manufacturing method for a disc-shaped support

Abstract

The invention relates to a wire arc additive manufacturing method for a disc-shaped supporting component. The wire arc additive manufacturing method comprises the steps of forming an internal circular ring of the disc-shaped supporting component; forming connecting ribs of the disc-shaped supporting component; forming an external circular ring of the disc-shaped supporting component; and making the internal circular ring, the connecting ribs and the external circular ring of the disc-shaped supporting component reach the required height. According to the wire arc additive manufacturing method for the disc-shaped supporting component, reference coordinate points of the internal circular ring, the external circular ring and the reinforcing ribs in the forming process are obtained through selection of datum points and coordinate transformation; the number of times of searching for demonstration points is greatly reduced; demonstration workload of operators is reduced; product manufacturing efficiency is improved; transportability of a robot program is enhanced; rapid formation of the disc-shaped supporting component manufactured through wire arc additives is achieved; and meanwhile, the wire arc additive manufacturing method with demonstration point searching replaced with coordinate transformation is adopted, disc-shaped supporting components which are different in size and provided with different connecting ribs can be formed, and higher universality is achieved.

Description

technical field [0001] The invention relates to an arc fuse additive manufacturing method for a disc-shaped support member, which belongs to the technical field of additive manufacturing, and is especially suitable for the arc fuse additive manufacturing technical field of a TIG (Tungsten Inert Gas) power supply. Background technique [0002] Wire Arc Additive Manufacture (WAAM) is a method of using the principle of layer-by-layer cladding, using the arc as the heat source, adding wire, and under the control of the program, according to the three-dimensional digital model. -The body is gradually formed into advanced digital manufacturing technology of metal parts. The hardware of the arc fuse additive manufacturing system platform is generally composed of main equipment such as robots, positioners, welding machines, and wire feeders. The control of the main input and output devices by the robot program is realized through the connection of the communication interface. At pr...

Problems solved by technology

At present, the intelligence of arc fuse additive manufacturing technology is low, and it is not enough to realize the direct conversion from 3D digital model to robot control language. It is necessary to manually analyze the characteristics of the 3D model, and then formulate the forming strategy and plan the forming path. Finally realize the preparation of the robot program

[0003] At present, in robot programming, the teaching method is generally used to determine the position of the teaching point. The teaching point is basically determined by the naked eye, and it is difficult to repeat positioning and alignment. The more complex the workpiece, the more the number of teaching points will greatly increase the workload. , resulting in low programming efficiency and accuracy

In the arc fuse additive manufacturing process, when the program is interrupted and restarted, it is generally necessary to modify the teaching point of the program, so that the position accuracy of the teaching point is not high, the programming workload is large, and the portability is not high
