Abstract

The invention discloses an electric arc spray nozzle. The electric arc spray nozzle comprises a support, an air cap, a nozzle cap, a front cover plate, an air nozzle, nozzle bases, nozzle tips and feeding mechanisms, wherein the air nozzle is fixed to the front end of the support, the nozzle bases are fixed to the support, and are arranged on the two sides of the air nozzle respectively, the nozzle tips are arranged at the front ends of the nozzle bases, the feeding mechanisms are connected with the rear ends of the nozzle bases, the front cover plate is arranged at the front end of the support, the nozzle cap is arranged at the front end of the front cover plate, and the air cap is connected with the front portion of the nozzle cap in a sleeved mode. According to the mode, the electric arc spray nozzle has the advantages of being high in reliability and good in electrical conductivity, having the clean surface, being low in requirement for the diameter tolerance of materials and capable of achieving two times of atomization and automatic cleaning of metal wires, and having wide market prospect in the surface spraying market.

Description

technical field [0001] The invention relates to the field of surface spraying, in particular to an arc spraying head. Background technique [0002] Arc spraying is a technology that uses an electric arc that burns between two continuously fed metal wires to melt metal, atomizes the molten metal with high-speed airflow, and accelerates the atomized metal particles so that they are sprayed to the workpiece to form a coating. . Arc spraying is the most commonly used thermal spraying method in practical application projects such as steel structure corrosion protection, wear resistance and mechanical parts maintenance. A general arc nozzle consists of a bracket, a shield, an air cap, a nozzle cap, a front cover, an air nozzle, a nozzle seat, a nozzle tip, and a feeding mechanism. This structure has problems such as easy blockage of the nozzle, low conductivity, easy breaking of the electric arc, and unsatisfactory spraying effect. Contents of the invention [0003] The techn...
