一种材料表面电火花喷丸强化装置

本实用新型涉及材料加工技术领域，公开了一种材料表面电火花喷丸强化装置，包括工作槽、电源、遮蔽部及工具电极，工作槽内设有工作液，电源的两极分别与待加工工件、工具电极电连接，遮蔽部位于工具电极与待加工工件之间，且遮蔽部覆盖于待加工工件的待加工区域，工具电极与遮蔽部之间形成工作空间，工作空间淹没于工作液中，工作空间内能够产生电火花放电。通过该装置对材料表面处理后能够达到类似常规喷丸的效果，可以提高材料表面硬度、耐磨性及疲劳强度，增加其使用寿命，且该装置的成本较低、操作便捷，喷丸效果较均匀。

The utility model relates to the technical field of material processing. The utility model discloses a material surface electric spark shot peening strengthening device. The device comprises a workinggroove, a power supply, shielding parts and tool electrodes, a working solution is arranged in the working tank; wherein two poles of the power supply are electrically connected with the to-be-machined workpiece and the tool electrode respectively, the shielding part is located between the tool electrode and the to-be-machined workpiece and covers a to-be-machined area of the to-be-machined workpiece, a working space is formed between the tool electrode and the shielding part, the working space is submerged in the working liquid, and electric spark discharge can be generated in the working space.
