Abstract

The invention relates to the technical field of friction stir welding, in particular to a multi-material friction stir additive device. The multi-material friction stir additive device has an additive channel and a guide cavity arranged coaxially with the additive channel, the guide cavity is arranged above the additive channel, and at least two guides are movably arranged therein, The guides are arranged around the axis of the guide cavity; each of the guides is adapted to guide different additive materials to move toward the additive channel, so as to extend the additive material into the additive channel , The supply of different additive materials is realized through different guides for additive printing with alternate changes of multiple materials, which can quickly realize alternate additive manufacturing of multiple materials, avoiding the problem of low efficiency of additive manufacturing by replacing bars multiple times. , thereby simplifying the additive manufacturing process and improving efficiency.

Description

technical field [0001] The invention relates to the technical field of friction stir welding, in particular to a multi-material friction stir additive device. Background technique [0002] As an emerging technology, additive manufacturing can quickly realize the manufacture of complex parts, which has great engineering significance. Traditional laser additive manufacturing needs to melt and resolidify materials, which greatly reduces material properties. The newly developed friction stir additive manufacturing technology realizes solid-phase material addition, and fundamentally avoids various defects caused by melting of materials. However, in the case of friction stir additive manufacturing, it is difficult to apply the working conditions that require multiple materials to be used together, and the bars need to be replaced many times for additive manufacturing, and its work efficiency is low. SUMMARY OF THE INVENTION [0003] Therefore, the technical problem to be solved...
