Abstract

The invention discloses a friction stir welding additive manufacturing device and method capable of continuously feeding rods. Comprising a welding mechanism, a first feeding mechanism, a second feeding mechanism and a feeding mechanism, wherein the welding mechanism is used for stirring and rubbing an additive position and guiding a bar to axially move towards the additive position; the first feeding mechanism is used for driving the bar to axially move towards the additive position; the second feeding mechanism is used for driving the bar to axially move towards the additive position; the second feeding mechanism is arranged between the welding mechanism and the first feeding mechanism and located on the side of a bar moving in the axial direction, and the feeding mechanism is arranged between the first feeding mechanism and the second feeding mechanism and located on the side of the bar moving in the axial direction. The first feeding mechanism and the second feeding mechanism alternately drive the multiple bars to continuously move towards the material adding position. Automatic continuous feeding of the bars is achieved, and the device does not need to be stopped in the material adding process.

Description

technical field

[0001] The invention belongs to the field of welding technology, and in particular relates to a friction stir welding additive manufacturing device and method capable of continuously feeding rods. Background technique

[0002] The information disclosed in this background section is only intended to enhance the understanding of the general background of the present invention, and should not be considered as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art.

[0003] At present, metal additive manufacturing (3D printing) mostly adopts fusion welding method, that is, laser, arc, electron beam, etc. are used as heat sources. The working temperature is higher than the melting point of the material, and the base material is melted. Performance of 3D printed parts. Friction stir welding is a technology that utilizes the frictional heat generation and stirring action between t...
