Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with specific embodiments.

[0035] Such as figure 1 As shown, the present invention can be used in the arc additive method of large-scale parts manufacturing, and a rotating table is arranged under the welding head of the welding robot, and the rotating shaft of the rotating table is parallel to the central axis of the robot base;

[0036] Such as figure 2 As shown, the above-mentioned arc additive manufacturing method specifically includes the following steps:

[0037] Step 1. Analyze the digital model of the part in the slicing software of arc additive, and use the offset algorithm or parallel line scanning algorithm to generate the additive path;

[0038] Step 2, judging whether the first point in the additive path is within the reachable area of ​​the robot;

[0039] The specific judgment method is:

[0040] Set the reachable area radius of welding torch robot to 1000~1200mm;

[00...

Abstract

The invention discloses an electric arc additive manufacturing method capable of being used for large-size parts manufacturing. According to the method, the additive manufacturing of parts is carriedout on a rotatable rotating table, the mode that the rotatable rotating table is combined with a slicing program is realized, so that the large-size parts are firstly sliced and analyzed, whether therunning track of the program is located in the working area of the robot body or not is judged, the running track is matched with the rotating table to rotate in the program running process, the working area of the welding robot is expanded, so that the original unreachable region of the robot can be changed into a reachable region so as to achieve the purpose of manufacturing large-size parts; the method can be used for forming and manufacturing the large-size aviation structural parts.

Description

technical field [0001] The invention relates to a metal arc additive manufacturing method, in particular to an arc additive manufacturing method using a rotatable external shaft combined with a slicing program. The method can manufacture large-sized parts and belongs to the technical field of metal welding processing. Background technique [0002] Arc additive manufacturing is a manufacturing method that melts and accumulates metal layer by layer to achieve the shape of the workpiece. The traditional arc additive process usually uses slicing software to slice and plan the digital model of the parts, and then output the program to the welding robot for additive operations. Due to the limited working area of ​​the welding robot body, the traditional arc additive method cannot manufacture large-scale parts. Therefore, it is necessary to develop an arc additive method that can be used in the manufacture of large-scale parts. Contents of the invention [0003] Purpose of the ...
