Description

Automatic metal wire straightening and feeding mechanism for electric arc spraying Technical Field The application relates to the technical field of electric arc spraying, in particular to an automatic wire straightening and feeding mechanism for metal wires for electric arc spraying. Background Arc spraying is a thermal spraying process in which an arc is generated between two energized metal electrodes (usually wire or rod-like), the electrode material is melted by the high temperature of the arc, and the molten metal is atomized into fine particles by means of a high-velocity compressed air stream (e.g., compressed air) and sprayed onto the surface of a workpiece to form a coating, and a wire is used in the arc spraying. In the arc spraying process, the flatness of the consumable electrode of the wire directly affects the wire feeding stability and the spraying quality. The current industry is generally faced with the problem that the traditional process relies on manual straightening of metal wires, and has the remarkable defects that the manual straightening efficiency is low, potential safety hazards exist in manual operation, operators are easily scratched by sharp edges of the wires, and occupational fatigue risks are increased due to long-time repeated labor.
