The present invention relates to a device in the technical field of material
processing, in particular to a peener which carries out the
surface deformation strengthening process on
magnesium alloy samples. The present invention comprises a main
peening system, an upper
whirlwind separation system, a dedusting
system, an
air compression system and an electric system, wherein, the upper
whirlwind separation system is positioned on the upper end of the main
peening system, the lower part of the upper
whirlwind separation system is communicated with the main
peening system, the upper part is connected with the dedusting system, which is positioned outside the main peening system, the air inlets of both the dedusting system and the main peening system are connected with the
air compression system, and the electric system is connected with the main peening system, the upper whirlwind separation system, the dedusting system and the
air compression system. The present invention can conveniently assemble and disassemble the samples of the shaft class, the range of the generated peening strenghth is wide, the effect and uniformity of peening is good, and moreover,
pollution can be prevented.
