The air type blasting machine null which has the control mechanism of shot blasting material projection

摘要

PURPOSE: To provide an air-type blasting device, which can control the projection distribution of the polishing material easily and quickly without changing a nozzle and moving a nozzle position. ;CONSTITUTION: In an air-type blasting device for injecting the polishing material 5 from a nozzle to a work to be processed through a supply pipe with the compressed air, the nozzle is formed into the double structure, which consists of an outer pipe nozzle 1 and an inner pipe nozzle 2 arranged inside of the nozzle, and the polishing material 5, which is carried by the compressed air through a supply pipe 3 for the outer pipe nozzle 1, is injected from the outer pipe nozzle 1, and the compressed air is injected from the inner pipe nozzle 2 through a supply pipe 4 for the inner pipe nozzle 2. The inner pipe nozzle 2 is formed freely to be controlled so that the tip thereof is displaced by a driving mechanism part 8 in response to the tip of the outer pipe nozzle 1.;COPYRIGHT: (C)1993,JPO&Japio
