Embodiment Construction

[0030] The present invention will be further described below in conjunction with specific embodiments.

[0031] This embodiment provides an arc additive manufacturing process based on offline programming. The robot uses the Yaskawa MA1440 six-axis arc welding robot, which is matched with the Yaskawa DX200 control cabinet. Its six axes and six degrees of freedom can achieve more complex processing trajectories. ; The load weight of 6 kg can carry various servo welding guns and mounts, which are suitable for various arc welding equipment; the speed of the main shaft has increased by 80° / S, that is, from 2070° / S to 2150° / S; through high-speed action , Reduce the beat, realize the high-speed production operation, in the occasions where the robot needs to reciprocate multiple times or need to move long distances for welding, it can significantly increase productivity; the maximum horizontal extension distance of 1440 mm can support larger-size parts ; Repeated positioning accuracy can...

Abstract

The invention discloses an electric arc additional material manufacture technology based on off-line programming. The material of the additional material is aluminum alloy. The manufacture technologycomprises the following steps that: carrying out off-line programming on a robot program, and adopting an alternating current cold metal transition welding method to manufacture the additional material, wherein the alternating current cold metal transition welding method is a welding method which combines alternating current MIG (Melt Inert-Gas) / MAG (Metal Active Gas Arc) welding with cold metal transition welding, and the alternating current MIG welding is characterized in that a welding wire is taken as a molten electrode, inert gas or inert gas which adds a small quantity of active gas is used as protection gas. The cold metal transition welding comprises the following steps that: carrying out electric arc ignition; forward feeding the welding wire; when a molten drop enters a molten pool, extinguishing the electric arc, and reducing current; drawing the welding wire back to enable the molten drop to fall, and keeping short circuit current at a small value; and enabling the weldingwire to return back to a feeding state, carrying out molten drop transition, and circulating on the basis of the process. By use of the manufacture technology, the additional material manufacture of complex part blanks can be realized only through a robot and a welding machine, and other external equipment and hardware does not need to be used.

Description

Technical field [0001] The invention relates to the technical field of 3D printing, in particular to an arc additive manufacturing process based on offline programming. Background technique [0002] 3D printing technology is a kind of rapid prototyping technology, it is a kind of technology based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. [0003] In industrial manufacturing, some parts with a large number of curved surfaces and complex structures often need to waste a lot of raw materials and use expensive processing centers to complete the processing in traditional processing methods; such processing methods often require a lot of time and energy. Greatly increase the cost of parts processing. Summary of the invention [0004] In order to overcome the shortcomings of the prior art, the present invention provides an arc additive manufacturing process based on offline programming, which only ...
