Integrally Formed Fan Guard

Abstract

Disclosed are an integrally formed fan guard and its manufacturing method. The fan guard includes a top side and a circumferential side around the outer periphery of the top side, and the top and circumferential sides are formed by a metal plate by a single or multiple stamping and extrusion method. An air hole is formed by stamping at the top side or both of the top and circumferential sides for flowing air, and a central through hole is formed at the center position of the top side. In the manufacturing method, the fan guard is formed by stamping or extruding a steel plate directly by stamping and extrusion equipments. The invention does not require a high welding skill, and the fan guard so manufactured has the advantages of high efficiency, consistency, and pass rate, and thus reducing the production cost significantly.
