NON-POWERED SPRAY APPARATUS FOR SIMULTANEOUSLY SPRAYING CUTTING OIL AND COLD AIR

摘要

The present invention relates to a non-powered spray apparatus. The non-powered spray apparatus reduces work time and extends the service life of a tool during a cutting process, which is a generic term for drilling, milling, cutting, tapping, etc., by simultaneously injecting cutting oil and cold air for cooling the surface of a material to be processed and protecting a tip, and does not require an additional power source as the spray of the cutting oil and cold air is performed by a free-fall. The non-powered spray apparatus comprises: a cutting oil storage container; a venturi-type cold air supply unit which has an injection port, a cold and hot air separating room connected to the injection port, and a cold air supply room connected to the bottom of the cold and hot air separating room; a moving pipe which is connected to the cutting oil storage container and the bottom of the cold air supply room; and a spray nozzle which is connected to the bottom of the moving pipe.;COPYRIGHT KIPO 2016
