Abstract
The invention discloses a plasma arc cutting mechanism. A plasma gas cavity is formed in a plasma arc generator. An electrode is installed in the middle of the plasma gas cavity. The bottom of the plasma gas cavity shrinks inwards to form a conical nozzle. The small end of the conical nozzle is downward and serves as a plasma arc output end of the plasma arc generator. An annular cooling water groove is formed in the portion, on the outer ring of the conical nozzle, of the plasma arc generator. A water inflow end and a water outflow end are symmetrically arranged on the portion, on the outer wall of the plasma arc generator, of the annular cooling water groove. The water inflow end is connected with a pool through a circulating water pump. The pool is further communicated with the water outflow end. A workbench for containing a to-be-cut workpiece is arranged under the conical nozzle. A rectangular groove for containing waste residues is formed in the middle of the workbench. The rectangular groove for containing the waste residues is formed in the workbench and can be regularly cleaned, the nozzle is subjected to cooling by cooling water, the service life is prolonged, and good application prospects are achieved.
