Description
Изобретение относитс к области абра аивной обработки деталей. Известно пескоструйное устройство, содержащее воздушное сопло, уЬтановпен- кое в корпусе с образованием камеры разрежени , вставку и канал дл прохождени сжатого воздуха 1 « Недостатком известного устройства вл етс низка износостойкости вставки больша трудоемкость изготовлени пористого материа ш вставки, а также необ ходимос-гъ дополнительного использовани сжатого воздуха дл его подачи в : поры вставки. Целью изобретени вл етс повышени износостойкости вставки путем создани защитного абразивного сло . Цель достигаетс тетл, что вставка выполнена в виде металлической сетки, а канал дл прохождени сжатого воздуха сообщаетс с камерой разр жени . На чертеже показано устройство, общий вид. В корпусе 1 закреплены воздушное сопло 2, сообщенное с источником сжатого воздуха и вставка 3. Вставка 3 закреплена посредством втулки 4 и геЛк . 5, Камера разрежени 6 в корпусе 1 сообщаетс с трубопроводом 7 подачи абразивного песка, В KOJVпусе имеетс канал 8 и смесительна камера 9, Вставка 3 выпопвева вз метелпичес- кой сетки с размером чейки, равшьал размеру частицы абразивного песка. Наружна поверхность встагкн соединена с камерой разрежени 6 посредством кавапа Q. ГГёскоструйное устройство работает следующим образом, В сопло 2 подаетс сжатый воэлух. Под действием вьюоконапорной струи, выход5Щ1ей из сопла 2, в камере разрежени 6 создаетс разрежение. Из-за создавшегос разре}« ни в смесительную камеру 9 через трубопроводThe invention relates to the field of abrasive machining of parts. A sandblasting device is known which contains an air nozzle inserted in the housing to form a vacuum chamber, an insert and a passage for the passage of compressed air. 1 "The disadvantage of the known device is the low wear resistance of the insert, the greater laboriousness of manufacturing the porous material insert, and also using compressed air to supply it to: the pores of the insert. The aim of the invention is to improve the wear resistance of the insert by creating a protective abrasive layer. The goal is to reach the tetra, that the insert is made in the form of a metal grid, and the channel for the passage of compressed air communicates with the discharge chamber. The drawing shows the device, a general view. An air nozzle 2 connected to a source of compressed air and an insert 3 are fixed in the housing 1. The insert 3 is fixed by means of the sleeve 4 and geLx. 5, The vacuum chamber 6 in the housing 1 is connected to the pipeline 7 for supplying abrasive sand. In the KOJV bus there is a channel 8 and a mixing chamber 9, Insert 3 ejecting a mesh with a cell size equal to the size of the particle of abrasive sand. The outer surface of the vastaccano is connected to the rarefaction chamber 6 by means of a cavapa Q. The gyro jet device operates as follows. A compressed bucket is fed to the nozzle 2. Under the action of the side-jet jet, coming out of the nozzle 2, a vacuum is created in the vacuum chamber 6. Because of the permit that has been created} “not to the mixing chamber 9 through the pipeline
